How much does ChatGPT Business cost in the UK?

Direct answer

UK ChatGPT Business Standard seats cost £15 per user per month on annual billing, or £18 per user per month on monthly billing, exclusive of VAT, with a two-seat minimum. That is OpenAI’s UK chatgpt.com checkout on 18 September 2026, not a converted blog estimate. Enter a UK VAT number at checkout to keep VAT off the invoice; otherwise 20% VAT is added. OpenAI Help still publishes the international list as $20 / $25 USD.

  • UK annual: £15 / user / month excl. VAT (chatgpt.com, 18 Sep 2026)
  • UK monthly: £18 / user / month excl. VAT
  • Premium UK: £75 annual / £90 monthly excl. VAT
  • Billing: monthly or annual; annual is the cheaper checkout rate
  • Minimum: 2 paid seats (workspaces 2–200)
  • VAT: exclusive on OpenAI’s UK UI; 20% added without a VAT number
  • International list (OpenAI Help): $25 monthly / $20 annual USD
  • Plus vs Business: Plus is personal; Business is the team workspace
  • Business vs Enterprise: Enterprise is quote-only
  • Direct vs partner: same OpenAI product; partner can add discount code, setup, and GBP invoice

On OpenAI’s UK ChatGPT Business checkout, Standard seats are £15 per user per month billed annually, or £18 per user per month billed monthly, exclusive of VAT, with a two-seat minimum. VAT is added unless you enter a valid UK VAT number at checkout. OpenAI Help still lists the international rate as $20 annual / $25 monthly USD. UK checkout checked 18 September 2026 — confirm the live chatgpt.com figure before you budget.

Summary

UK checkout is in pounds, exclusive of VAT. Annual Standard seats were £15 per user per month on 18 September 2026; monthly was shown as £18. Premium seats were £75 annual / £90 monthly. Workspaces are 2–200 employees. ChatGPT Plus is a personal plan; Enterprise is quote-only. Buying through AI Build Group, a UK OpenAI SMB Channel Partner, does not change OpenAI’s product — it can add a genuine partner discount code, two hours of setup on qualifying UK and Ireland orders, and a GBP invoice.

“The seat price is never what breaks a ChatGPT Business budget. It's the credits nobody scoped, the Codex seat someone assumed was still included, and the two months of governance time nobody put in the business case. Price the rollout, not just the licence, and the ROI conversation with finance gets a lot easier.”

Evidence and sources

UK payable rates were taken from OpenAI’s chatgpt.com Business checkout on 18 September 2026: Standard £15 per user per month billed annually or £18 billed monthly, exclusive of VAT, for workspaces of 2–200 employees. Premium was shown at £75 annual / £90 monthly. OpenAI Help still publishes the international list as $20 annual / $25 monthly USD. Confirm the live chatgpt.com figure before you budget. AI Build implementation fees are separate from the OpenAI subscription.

Who delivers this

AI Build Group Ltd is a UK OpenAI SMB Channel Partner for ChatGPT Business. Partner purchase can add an eligibility-checked discount code, two hours of complimentary setup on qualifying UK and Ireland orders, and a GBP invoice; OpenAI’s product and checkout rates stay the same.

How much does ChatGPT Business cost in the UK?

ChatGPT Business is priced per seat by OpenAI. The live amount, billing term and any UK VAT should be confirmed at the point of purchase or partner quote because prices and tax treatment can change.

Can AI Build get us a ChatGPT Business discount?

AI Build checks whether your organisation can be registered or attributed through the relevant OpenAI partner route. If the current route supports a partner discount for your organisation, we explain the saving and buying steps before you commit.

Is there a minimum number of ChatGPT Business seats?

ChatGPT Business is a team workspace sold by seat. Minimum seat or user requirements can depend on the current OpenAI route and billing path, so AI Build confirms the requirement during the discount check.

Does the partner discount change VAT?

No. A partner discount can reduce the commercial price where available, but VAT is handled separately according to the billing route, tax status and applicable UK rules.

What happens after we check our discount?

AI Build confirms eligibility, explains the buying route, helps you plan seats and supports setup areas such as workspace ownership, admin controls, acceptable-use rules and adoption priorities.

How much is ChatGPT Business in the UK?

OpenAI’s UK ChatGPT Business checkout showed Standard seats at £15 per user per month on annual billing, or £18 per user per month on monthly billing, exclusive of VAT, on 18 September 2026. Every workspace needs at least two paid seats (2–200 employees). Enter a UK VAT number at checkout if the purchase should be VAT-exempt; otherwise VAT is added. OpenAI Help still lists the international rate as $20 annual / $25 monthly USD — use chatgpt.com for the UK payable figure, then get-offer for partner terms.

  • UK annual: £15 per user per month excl. VAT (chatgpt.com, 18 September 2026)
  • UK monthly: £18 per user per month excl. VAT

  • VAT: exclusive on the OpenAI UK UI; 20% added without a VAT number
  • International list: $25 monthly / $20 annual USD (OpenAI Help)

How much is ChatGPT in the UK?

On OpenAI’s UK checkout, ChatGPT Business Standard seats are £18 per user per month billed monthly, or £15 per user per month billed annually, exclusive of VAT, with a two-seat minimum. That figure was on chatgpt.com on 18 September 2026. ChatGPT Plus is a separate personal plan and is not this team price. Confirm the live chatgpt.com amount before you budget.

  • UK monthly: £18 per Standard seat excl. VAT
  • UK annual: £15 per Standard seat per month excl. VAT
  • Minimum: 2 paid seats
  • Plus: personal plan — not the Business checkout price

How much is ChatGPT per month in the UK?

The UK monthly price for a ChatGPT Business Standard seat is £18 per user, exclusive of VAT. Annual billing is £15 per user per month, paid up front for the year, and is the cheaper checkout rate. Both need at least two seats. Premium seats were £90 monthly or £75 annual, exclusive of VAT, and are not the standard monthly figure. Checked 18 September 2026 on chatgpt.com.

  • Standard monthly: £18 per user excl. VAT
  • Standard annual: £15 per user per month excl. VAT
  • Premium monthly: £90 per user excl. VAT (higher tier)

Does ChatGPT charge VAT in the UK?

Yes, unless you enter a valid UK VAT number at checkout. OpenAI’s UK ChatGPT Business prices are exclusive of VAT. Without a VAT number, 20% VAT is added. With a valid UK VAT or Tax ID, OpenAI treats the purchase as VAT-exempt.

  • Prices shown: exclusive of VAT
  • No VAT number: 20% VAT added
  • Valid UK VAT number: VAT kept off the invoice

Is there VAT on a ChatGPT subscription in the UK?

There is VAT on a UK ChatGPT Business subscription when checkout has no valid UK VAT number. The £18 monthly and £15 annual Standard rates are exclusive of VAT, so 20% is added in that case. Enter a valid UK VAT number and OpenAI keeps VAT off the invoice. The international OpenAI Help list in US dollars is a different figure from this UK checkout.

  • UK Standard rates are excl. VAT
  • 20% VAT without a UK VAT number
  • VAT-exempt checkout when a valid UK VAT number is entered

Is ChatGPT Business billed monthly or annually, and what is the minimum seats rule?

On OpenAI’s UK checkout you can pay monthly at £18 per Standard seat or commit annually at £15 per Standard seat per month, exclusive of VAT. The annual plan is the cheaper checkout rate; the monthly plan is the one to use while a pilot is still proving itself. The 2-seat minimum applies to every ChatGPT Business workspace — a one-person Plus subscription cannot be “upgraded” into Business without a second seat. Usage-based Codex-only seats are a different product and are not available to new Business workspaces after 24 June 2026.

  • Monthly billing: £18 per Standard seat per month excl. VAT, no annual lock-in
  • Annual billing: £15 per Standard seat per month excl. VAT, billed up front for the year
  • 2-seat minimum on every Business workspace (2–200 employees)
  • New workspaces cannot add a first Codex-only seat after 24 June 2026

How does ChatGPT Business pricing compare with Plus, Pro and Enterprise?

ChatGPT Plus is a personal subscription with consumer terms and no organisation admin. ChatGPT Business is the team plan: central billing, admin controls, and business data protections. UK Standard seats were £18 monthly / £15 annual excl. VAT on 18 September 2026, with a 2-seat minimum. ChatGPT Enterprise has no public list price — it is quote-only — and is the route when you need SCIM, exportable audit logs, custom retention or a formal SLA. OpenAI has also announced Premium Business seats (higher published UK rates of £90 monthly / £75 annual excl. VAT, currently waitlist) for heavier usage inside the same workspace; those are not the standard UK “ChatGPT Business cost” figure. See the plan comparison table above and the full Business vs Enterprise decision page for SSO, SCIM and procurement.

  • Plus: personal plan, no admin, consumer data terms
  • Business: UK £18 monthly / £15 annual excl. VAT, 2-seat minimum, SAML SSO, central billing
  • Enterprise: quote only — SCIM, audit export, custom retention, SLA
  • Premium Business seats: UK £90 monthly / £75 annual excl. VAT, waitlist — not the standard list price

Enterprise options

What is included in a ChatGPT Business seat, and what does AI Build add?

A standard ChatGPT Business seat includes ChatGPT and Codex access, GPTs, Projects, Apps, Company Knowledge, and baseline Agent, Deep Research and voice/image usage, with optional workspace credits if you exceed per-seat limits. The product is the same whether you buy direct from OpenAI or through AI Build Group. The partner route adds eligibility for a genuine OpenAI SMB Channel Partner discount code, two hours of complimentary remote setup on qualifying UK and Ireland purchases, and optional governance or adoption consulting. That is not a generic internet coupon: codes are issued after an eligibility check. Current partner-offer availability is confirmed on the ChatGPT Business partner discount code page, not guessed from promo-code round-ups.

  • Included: ChatGPT + Codex in one workspace, admin, central billing, business data protections
  • Optional: pooled workspace credits beyond per-seat feature limits
  • AI Build partner: discount code where eligible, two hours of setup, rollout support
  • Not included: a public “ChatGPT promo code” scraped from coupon sites

Is partner pricing or an AI Build offer available?

OpenAI’s published UK list price does not change when you buy through AI Build Group. What can change is the commercial wrap: a genuine OpenAI SMB Channel Partner discount code after eligibility review, two hours of complimentary remote setup on qualifying UK and Ireland orders, and optional governance or adoption consulting. Request that offer on the ChatGPT Business partner discount code page. Seat prices, VAT and the team-size cost ladder stay on this pricing page.

  • List price: OpenAI’s UK chatgpt.com checkout — not set by AI Build
  • Partner offer: eligibility-checked discount code, not a public coupon
  • Qualifying UK/Ireland orders: two hours of complimentary remote setup
  • Conversion owner: /chatgpt-business/get-offer — this page owns cost

Are there additional implementation or support costs?

Yes, if you want licences to stick. The OpenAI seat line is only the subscription. Most UK SME rollouts also budget onboarding, an AI use policy, starter workflows, and optional workspace credits if advanced features exceed per-seat limits. AI Build’s partner offer can include two hours of complimentary remote setup on qualifying purchases; extra governance, training or assistant work is scoped separately. Use the TCO and hidden-cost sections below before you finalise a business case.

  • Always: per-seat subscription plus VAT treatment at checkout
  • Usually: policy, onboarding and pilot-training time in weeks two to six
  • Optional: workspace credits beyond per-seat feature limits
  • Partner setup hours: complimentary on qualifying UK and Ireland orders; extra consulting is separate

Is ChatGPT Business suitable for UK SMEs?

Yes, when two or more people already use ChatGPT at work and you want central billing, admin controls and business data protections without Enterprise extras such as SCIM, exportable audit logs or a formal SLA. The UK checkout has a two-seat minimum. AI Build Group, a UK OpenAI SMB Channel Partner, helps SMEs move from personal accounts to a governed workspace. You still buy OpenAI’s product; the partner layer is eligibility, setup and optional consulting.

  • Fit: teams of 2–200 that need a governed workspace, not a personal Plus login
  • Not a fit: one-person use (Plus) or named Enterprise controls (SCIM, audit export, SLA)
  • UK checkout: pounds, exclusive of VAT, two-seat minimum
  • Partner help: discount code, setup and rollout — not a different OpenAI product

Do UK buyers pay in GBP, and is VAT added?

Yes — OpenAI’s UK ChatGPT Business checkout is already in pounds and labelled exclusive of VAT. That is the UK payable rate, not a converted USD blog figure. If you enter a valid UK VAT/Tax ID at checkout, OpenAI treats the purchase as VAT-exempt. Without a VAT number, 20% VAT is added. A UK OpenAI SMB Channel Partner may still quote or invoice in GBP after eligibility review; that is the partner commercial layer, not a different OpenAI product.

  • UK checkout: £18 monthly / £15 annual per Standard seat, exclusive of VAT
  • VAT: off the invoice with a valid UK VAT number; otherwise 20%
  • Partner quotes: may be issued in GBP after eligibility review
  • Always check the amount shown on chatgpt.com or the partner proposal

What does ChatGPT Business total cost of ownership include?

The subscription line is only part of the real cost. A credible TCO figure adds onboarding effort, an AI use policy, workflow design for pilot use cases, optional workspace credits if usage exceeds per-seat limits on advanced features, and time spent training pilot users — most of which lands in weeks two to six of rollout, not on the invoice itself. See the hidden costs section below before you finalise a business case.

  • Per-seat subscription cost
  • Onboarding and workspace configuration
  • Governance and AI use policy work
  • Workflow design and pilot training time
  • Optional workspace credits for usage beyond per-seat feature limits

What does ChatGPT Business cost for a 5, 10, 25, or 50-seat team?

Team-size cost scales linearly with seats, since ChatGPT Business list pricing has no volume discount tier below Enterprise — five seats costs five times the per-seat rate, fifty seats costs fifty times. The ladder below uses OpenAI’s UK checkout of £18 monthly / £15 annual per Standard seat, exclusive of VAT (18 September 2026), so you can sanity-check any partner quote against the live UK figure.

How does ChatGPT Business partner free-seat pricing work?

Partner free-seat pilots reduce your effective per-seat cost during the first commitment period rather than changing OpenAI's published list price. If a qualifying UK or Ireland order includes complimentary pilot seats alongside paid seats, divide the total contract cost by the full seat count — paid plus free — to get the blended rate finance should see. A 10-seat order with two complimentary pilot seats, for example, blends the paid-seat cost across all 10 users instead of the 8 seats actually invoiced, which is the number that belongs in the business case rather than the sticker price of the paid seats alone.

How does ChatGPT Business pricing compare to Microsoft 365 Copilot's true cost?

Microsoft 365 Copilot's headline add-on price is not the number that lands on your budget. Copilot's business-tier add-on (for organisations under roughly 300 seats) commonly lists at around $21 per user per month on an annual commitment, while Copilot's enterprise-tier add-on lists at $30 per user per month — but both require an eligible Microsoft 365 base licence underneath, typically Business Standard, Business Premium, E3, or E5. Once you stack the required base plan on top of the add-on, the realistic all-in cost commonly lands between roughly $34 and $90 per user per month depending on your existing Microsoft 365 tier — verify current Microsoft pricing before comparing, since these figures move and vary by region. ChatGPT Business, by contrast, is a standalone UK checkout of £18 monthly / £15 annual per Standard seat excl. VAT, with no required Microsoft base licence, which usually favours ChatGPT Business on a true-cost basis for teams that do not already need the underlying Microsoft 365 upgrade for other reasons. See our full plan comparison for the wider Enterprise decision.

  • ChatGPT Business: UK £18 monthly / £15 annual per seat excl. VAT, no base licence required
  • Copilot business-tier add-on: roughly $21 per seat per month plus a required M365 Business Standard/Premium base licence
  • Copilot enterprise-tier add-on: $30 per seat per month plus a required M365 E3/E5 base licence
  • All-in Copilot cost typically lands around $34–90 per seat per month once the base licence is included

What ROI formula justifies ChatGPT Business pricing to finance?

A defensible ROI formula is: (hours saved per seat per week × hourly cost × seat count × 52) minus (annual licence cost plus rollout cost) equals net annual value. The hours-saved figure is the part most business cases get wrong by guessing — use a conservative, function-specific benchmark instead of a blanket productivity claim. McKinsey's research on generative AI's economic potential documented a controlled study of 5,000 customer service agents in which generative AI assistance increased issue resolution by 14 percent per agent-hour and cut average handling time by 9 percent — a specific, sourced figure finance can interrogate, unlike a generic 'saves everyone an hour a day' assumption. Run the same formula against your own pilot data once you have two to four weeks of usage, and replace the McKinsey benchmark with your measured number as soon as you have one.

  • Hours saved per seat per week × hourly cost × seats × 52 = gross annual value
  • Gross annual value minus annual licence and rollout cost = net annual value
  • Cited benchmark: 14% faster issue resolution, 9% shorter handling time (McKinsey generative AI productivity research)
  • Replace the benchmark with your own pilot data once you have real usage to measure

What hidden costs sit behind ChatGPT Business pricing?

The per-seat subscription line is the smallest part of most ChatGPT Business budgets once three items are properly scoped. First, workspace credits: standard seats include per-seat limits on advanced features such as Deep Research, Agent, Voice, and image generation, and a workspace owner can optionally purchase pooled credit packs to unblock users who exceed those limits — budget for this if your pilot workflows lean on advanced tools. Second, Codex: standard seats include baseline ChatGPT and Codex access, but usage-based Codex seats with their own credit requirements are no longer available to new Business workspaces, or to workspaces that never added one before 24 June 2026 — if a proposal still assumes standalone Codex seat economics, confirm that against current OpenAI Help articles before it goes into a budget. Third, governance time: policy work, review gates, and pilot training rarely appear on an invoice but reliably consume real hours in weeks two to six of rollout.

  • Workspace credits — optional, pooled, for usage beyond per-seat feature limits
  • Codex seat changes — usage-based Codex seats closed to new workspaces from 24 June 2026
  • Governance and policy time — rarely invoiced, always real
  • Pilot training hours — the cost most business cases forget to scope

Per-seat pricing is only one line on the invoice

Finance sees ChatGPT Plus on expense claims while IT has no workspace to govern. Business pricing plus partner codes often beats unmanaged individual spend — but the real number includes onboarding, policy work, and adoption support if you want licences to stick.

When partner pricing makes sense

  • Three or more people already use personal AI accounts for work
  • Leadership wants central billing and usage visibility
  • You need discount codes and complimentary setup on qualifying purchases
  • You want rollout support from the same UK partner team

Stop invisible AI spend on personal cards

Move to central billing with partner pricing so finance sees one governed workspace at a known per-seat rate — not dozens of untracked Plus reimbursements at unpredictable renewal dates.

Direct answers

Quick answers

How much is ChatGPT Business in the UK?
On OpenAI’s UK chatgpt.com checkout, ChatGPT Business Standard seats are £15 per user per month billed annually, or £18 per user per month billed monthly, exclusive of VAT, with a two-seat minimum. Without a valid UK VAT number, 20% VAT is added. OpenAI Help still lists the international rate as $20 annual / $25 monthly USD. Checked 18 September 2026 — confirm the live chatgpt.com figure before you budget. A partner discount code can change the quote; it does not replace OpenAI’s published UK price.
Is ChatGPT Business cheaper than everyone buying Plus individually?
For teams, Business often costs less per person than unmanaged Plus subscriptions once central billing, admin controls, and partner pricing are included. The bigger saving is avoiding shadow AI incidents and duplicate personal spend that finance cannot see or govern.
What does partner pricing include?
Eligible UK workspaces can receive discount codes, two hours of complimentary remote setup on qualifying purchases, and optional governance or adoption consulting from the same partner team — not just a licence transaction from OpenAI directly.

Is ChatGPT Business priced in GBP or USD, and do I pay VAT?

UK organisations see OpenAI’s ChatGPT Business checkout in pounds, labelled exclusive of VAT. Enter a valid UK VAT/Tax ID at checkout to treat the purchase as VAT-exempt; otherwise 20% VAT is added. OpenAI Help still publishes the international list in USD ($25 monthly / $20 annual). A UK partner quote may also be issued in GBP after eligibility review.

Is there a real ChatGPT Business promo code or discount?

Yes — but only as a genuine OpenAI SMB Channel Partner offer after an eligibility check, not as a public coupon scraped from voucher sites. Request a code on the ChatGPT Business get-offer page. AI Build Group emails eligible UK and Ireland codes, usually within one business day.

How much does ChatGPT Business cost per user?

On OpenAI’s UK checkout, Standard seats are £18 per user per month billed monthly, or £15 per user per month billed annually, exclusive of VAT, with a 2-seat minimum — checked 18 September 2026. OpenAI Help lists $25 / $20 USD internationally. UK partner discount codes and free-seat pilots can change the partner quote — request a code on the get-offer page.

Is ChatGPT Business cheaper annually?

Yes on OpenAI’s UK checkout. Annual billing was £15 per Standard seat per month versus £18 monthly, exclusive of VAT, on 18 September 2026. The 2-seat minimum still applies. Confirm the live chatgpt.com rate before you commit.

Is ChatGPT Business suitable for UK SMEs?

Yes, when two or more people already use ChatGPT at work and you want central billing, admin controls and business data protections without Enterprise extras such as SCIM, exportable audit logs or a formal SLA. The UK checkout has a two-seat minimum. AI Build Group, a UK OpenAI SMB Channel Partner, helps SMEs move from personal accounts to a governed workspace without changing OpenAI’s product.

Are there additional implementation or support costs?

Yes if you want licences to stick. Budget onboarding, an AI use policy, starter workflows, and optional workspace credits beyond per-seat limits. Two hours of complimentary remote setup can be included on qualifying UK and Ireland partner purchases; extra governance or training is scoped separately. Request those extras on the ChatGPT Business partner discount code page.

What is the difference between ChatGPT Plus and Business?

ChatGPT Plus is a personal subscription with consumer terms and no organisation admin. ChatGPT Business is the team plan: central billing, admin controls, SAML SSO, and business data protections. UK Standard seats were £18 monthly / £15 annual excl. VAT on 18 September 2026, with a two-seat minimum. Plus cannot be upgraded into a one-seat Business workspace.

How does buying ChatGPT Business through an OpenAI SMB Channel Partner work?

The product remains OpenAI’s ChatGPT Business. A UK OpenAI SMB Channel Partner such as AI Build Group can run an eligibility check, issue a genuine partner discount code, provision the workspace, and — on qualifying UK and Ireland purchases — include two hours of complimentary remote setup. Some partners can invoice in GBP. Current offer terms are confirmed on the get-offer page, not guessed from coupon sites.

What does AI Build provide alongside the ChatGPT Business licence?

AI Build Group does not replace OpenAI as the product vendor. Alongside the licence it can add a partner discount code where eligible, two hours of complimentary remote setup on qualifying purchases, and optional governance, training, or adoption consulting from the same UK team. Request those extras on the get-offer page.

Is Business cheaper than ChatGPT Plus for teams?

For teams, Business often costs less per person than everyone buying Plus individually once central billing and admin controls are included — plus you eliminate unmanaged shadow AI risk.

Does ChatGPT Business pricing change with team size?

The per-seat rate stays consistent; total spend scales linearly with the number of seats you provision — five seats costs five times the per-seat rate, fifty seats costs fifty times, with no volume discount tier below Enterprise. Most UK SME rollouts start with a small pilot cohort and expand seats once adoption metrics justify it, rather than licensing the whole organisation on day one.

What counts toward ChatGPT Business total cost of ownership?

Per-seat subscription cost, onboarding and workspace configuration, governance and AI use policy work, optional workspace credits, and workflow design or pilot training time. The subscription line is usually the smallest of these once you account for a proper rollout.

Should we budget for implementation?

Yes. Licence cost alone does not cover policy templates, pilot users, training, or measurement. Most UK SME rollouts include modest onboarding effort in weeks two to six.

Where do I get a ChatGPT Business partner discount code?

Request one from the ChatGPT Business partner offer page. AI Build Group emails eligible UK and Ireland codes after a quick eligibility check, usually within one business day.

What does ChatGPT Business pricing look like for a 25-seat team?

At OpenAI’s UK checkout on 18 September 2026, 25 Standard seats run £450 per month billed monthly, or £375 per month (~£4,500 per year) billed annually, exclusive of VAT — before any partner discount code or free-seat pilot. See the cost ladder above for 5, 10, and 50-seat figures, and verify the live chatgpt.com rate before finalising a budget.

Is Microsoft 365 Copilot cheaper than ChatGPT Business?

Not usually, once you count the required Microsoft 365 base licence. Copilot's add-on price is roughly $21–30 per seat per month, but it needs an eligible M365 base plan underneath, pushing the realistic all-in cost to somewhere around $34–90 per seat per month. ChatGPT Business is a standalone UK checkout of £18 monthly / £15 annual per Standard seat excl. VAT, with no base licence required — verify current Microsoft pricing before you compare, since figures vary by tier and region.

What ROI formula should we use to justify ChatGPT Business pricing?

(Hours saved per seat per week × hourly cost × seat count × 52) minus (annual licence cost plus rollout cost) equals net annual value. Use a conservative, function-specific benchmark for the hours-saved figure — McKinsey's research on generative AI documented a 14% gain in per-hour issue resolution and a 9% cut in handling time for one customer-service function — then replace that benchmark with your own pilot data once you have real usage.

Are workspace credits and Codex included in ChatGPT Business pricing?

Standard seats include baseline ChatGPT and Codex access within the per-seat limits, but usage beyond those limits requires optional, pooled workspace credits that a workspace owner purchases separately. Usage-based Codex seats with their own credit requirements are no longer available to new Business workspaces, or to workspaces that never added one before 24 June 2026 — confirm current terms on OpenAI Help before budgeting for standalone Codex seat usage.
