During a ChatGPT Business trial, test five real jobs with redacted data, time the correction of each output, check admin and sharing controls, and work out the paid seats needed afterwards. Keep paying only if the reviewed work justifies the checkout total. OpenAI publishes no standard Business trial, so read your own offer and renewal terms first.
A generic prompt such as “write a nice email” can make almost any assistant look good. A useful evaluation has source material, a known answer or approval rule, a named staff reviewer and a time limit. If no free Business offer appears at checkout, the same plan can be run during a deliberately limited monthly paid evaluation. Do not label a Plus promotional trial as a Business team trial.
Capture the offer before the clock starts
OpenAI's current Business signup guide describes choosing paid Standard or Premium seats and monthly or annual billing at checkout. The same guide says a new workspace must start with at least two paid seats, although OpenAI's single-seat page says some new workspaces are offered one. Its separate promotional-trial guidance says offers vary by account, plan, eligibility, duration, payment requirement and renewal behaviour. It does not establish a standard free Business trial. Before confirming anything, record the exact plan, start and end dates, number and type of seats, payment method, date of first charge, cancellation route and whether ending early cuts off access. Save the offer screen and confirmation email.
Put a decision meeting on the calendar before any renewal or conversion date. OpenAI's promotion guidance says some offers become paid subscriptions and advises cancellation at least 24 hours before renewal where applicable; the specific offer controls. If the workspace is paid monthly from day one, calculate that first month as an evaluation cost. Use the official USD Business list rates as a benchmark: two Standard seats are $50 on monthly billing, before local variation and tax. Do not commit annually merely because its monthly-equivalent rate is lower until the trial has answered the task questions.
An illustrative tutoring centre sees a promotional banner, but the details say it applies to an individual Plus account. Its owner wants two tutors to share a managed workspace. That promotion is not a test of Business membership or admin settings. The corrected plan is to inspect Business checkout, choose the smallest suitable monthly purchase if no Business offer is available, and keep the evaluation deadline in the centre's calendar. The one-person seat comparison helps if only the owner will test.

Buy nowPrepare a five-job test pack from existing work
Choose five tasks the team already performs often enough to matter. Each pack should contain a redacted input, the current method, a standard for an acceptable output and the reviewer. Prepare the packs before using ChatGPT so the evaluation is not biased by choosing only tasks that gave pleasing answers. Record total human time, including preparation, correction and approval. A fast first draft is not a saving if the reviewer must rebuild it from scratch.
| Job | Input | Pass condition | Reviewer |
|---|---|---|---|
| Enquiry reply | Redacted incoming email and approved service terms | Correct next step, no invented promise | Customer lead |
| Meeting action list | Short notes with owners and dates | Every action traced to the notes | Meeting chair |
| Spreadsheet exceptions | Sample orders with one known discrepancy | Finds discrepancy and shows calculation | Operations owner |
| Policy comparison | Two versioned internal documents | Names changed clauses accurately | Document owner |
| Short public copy | Approved facts and style constraints | No invented claims or missing detail | Publishing owner |
These five jobs test distinct behaviour: following rules, extracting actions, handling numbers, comparing documents and writing to a brief. A bookshop could use a supplier enquiry, event-planning notes, a stock discrepancy sheet, two delivery policies and an approved event listing. A removals firm would use a quote enquiry, dispatch notes, mileage anomalies, terms versions and a service-page paragraph. The business type changes, but each test still needs a known answer and a person able to judge it.
Job one: a reply that may not invent a promise
Give the assistant an illustrative customer message: “Can you collect the bookcase this Friday, and will it cost the same as the estimate?” Provide a redacted availability note saying Friday is unconfirmed and a policy saying the estimate changes only after a revised item list is accepted. Ask for a reply under 120 words, using “[first name]” and making no booking or price promise. The expected result asks for the missing item details and says the team will confirm availability and price. It does not state that Friday is booked.
A realistic model output may sound polished but say, “We can collect on Friday at the quoted price.” Mark that as a fail even if the tone is good. Correct it to: “We can check Friday availability once we have the revised item list. We will then confirm whether the estimate changes before you decide.” Time both drafting and correction. If the assistant repeatedly invents availability despite a clear source note, the job may need a stronger prompt or should stay with a person. The operations task tutorial gives more low-risk candidates.
Job two: actions from a messy meeting note
Use an illustrative 200-word note with decisions, open questions and at least one ambiguous owner. For a landscaping company: “Replace the damaged mower belt; supplier can deliver next week. [first name] to call the client about access. The rainy-day schedule may need moving. Confirm fuel receipts before payroll.” Ask for three columns: action, named owner or “unassigned”, and due date only if stated. The known answer is that the belt order and client call are actions, while the rainy-day schedule is unresolved and must not gain a fabricated date.
Inspect whether the assistant treats an idea as a decision or invents a person. An illustrative output might assign the schedule change to the operations manager and say “by Thursday”, neither of which appears in the note. The correction is to mark both as “owner to confirm”. Log the minutes saved only after the chair checks the list. If the job passes, save the approved action list in the team's usual task system; do not expect colleagues to search an individual's private chat later.
Job three: a numerical exception with a visible calculation
Prepare a small, synthetic spreadsheet. An independent bookshop might have three purchase orders: 12 copies at $8, 10 at $9 and 5 at $12. Supplier invoice quantities are 12, 11 and 5. The expected discrepancy is one extra $9 copy, assuming the unit rates are unchanged. Ask the assistant to compare quantity and extended line amount, show the row of the difference and say what a human must check before disputing the invoice. The reviewer should be able to reproduce the arithmetic without trusting the model.
If the output says there is a $9 overcharge but does not show that 11 minus 10 equals one unit on the second line, score it as incomplete. If it flags the first line because it mistakes a stock code for quantity, fail it. The reviewer should check whether a substitute title or approved short shipment explains the number. This test is about finding and explaining a discrepancy, not issuing a supplier claim automatically. For more on spreadsheet tasks, the ChatGPT spreadsheet guide provides background.
Job four: a changed policy clause, with citations
Give the assistant two short, versioned policy extracts with one true change and one unchanged clause. For an illustrative tutoring centre, version A says cancellations need 24 hours' notice; version B says 48 hours. Both versions keep the same lesson rescheduling limit. Ask the assistant to list only changed clauses, quote no more than needed, identify the version and flag ambiguous wording. The reviewer checks the exact source sentence. An answer that invents a changed rescheduling limit fails even if it spots the notice change.
Also test the data handling rule. If the source policy contains pupil names, replace them with placeholders before upload. A successful result can be used to draft an internal change note, but a manager must approve the policy interpretation before staff use it. The test output should never silently become the live customer terms. Record whether the assistant could cite the right passage and how long the manager took to verify it; a missing citation may make a plausible summary too expensive to trust.
Job five: public copy from approved facts
Provide a seven-line fact sheet for a bookshop event: date, time, accessibility note, ticket rule, host role, book title and approved booking link. Ask for a 90-word listing and a 30-word reminder, with no invented speaker biography or discount. Compare the two outputs with the fact sheet. This test reveals whether the assistant can produce useful public copy from a bounded source without smuggling in unsupported claims. It also tests whether the team can reuse a prompt without needing a specialist writer each time.
An illustrative first output may call the event “free” when the fact sheet merely says “booking required”. The fix is to remove any price claim and ask the owner to supply the actual ticket rule. Record that as one factual error, not a stylistic preference. If three people review the same copy and each find a different unsupported claim, the supposed speed gain is doubtful. If it passes, publish through the normal approval process and record the final link outside ChatGPT.
Test the Business controls as well as its answers
Invite only the staff needed for the evaluation, with their own accounts. Check roles, seat types, workspace discovery, connected apps, sharing, memory and credit settings before real work; OpenAI's admin guide says apps are enabled by default in Business, so switch off any the test does not need. Business members can invite others where paid capacity exists, so tell testers not to expand the group informally. OpenAI says Business shared links are restricted to authenticated workspace members, yet Business cannot disable all shared links workspace-wide. Rehearse sharing a synthetic conversation and deleting its link. The owner admin checklist provides a fuller pre-invite sequence.
Use a non-sensitive permission test. Give one member a synthetic purchase-order file that another member should not see as a private chat. Check whether it remains private until intentionally shared, then share a separate project and observe what the invited person can see. Ask testers to switch between personal and Business workspaces and identify which one they are using. A fine output produced in the wrong workspace is a failed trial of team practice. Record any app authorisation requested and reject unexpected write or send permissions.
OpenAI says Business data is excluded from model training by default, but that is not a reason to upload every customer record during a short evaluation. Use redacted or invented material until the owner has approved the data classes and relevant contractual terms. Check where the final version of each output will live. Business member chat history is private by default, so a workflow that depends on a colleague opening the originator's chat later has a handover problem even if the first answer is good.
Score the trial with time and error costs
For each job, record baseline minutes, AI preparation minutes, generation minutes, correction minutes and final approval minutes. Add them rather than counting only generation. Also log factual errors, unsupported claims, missing source references and permission surprises. Use a simple pass rule: the output must meet the task's mandatory accuracy and data conditions; only then compare time. An error in a customer promise can outweigh several minutes saved elsewhere.
An illustrative six-person removals firm tests five jobs once each. Its baseline minutes are 20, 15, 25, 30 and 18, totalling 108. AI-assisted totals, including review, are 13, 12, 27, 20 and 11, totalling 83. The net observed difference is 25 minutes across those five samples. That is a small pilot result for this invented firm, not a forecast. The spreadsheet job got slower by two minutes and should not be counted as a win. Repeat the passing jobs on different source material before using a monthly saving estimate.
The firm should also classify the value. If the five jobs are performed weekly, the pilot difference might suggest 100 minutes in a four-week month, but only if future tasks resemble the tested ones and the reviewers keep the same standard. Do not multiply a single best-case output by every employee and call it an ROI. If the subscription requires three Standard seats at a $75 monthly USD list benchmark, the owner can ask whether those 100 reviewed minutes and any quality benefit justify that cost. The answer depends on the firm's actual labour cost and work volume, which the firm should supply.
Make the keep, narrow or cancel call
Keep the Business workspace if at least a few recurring jobs pass the accuracy and data gates, staff can operate the admin rules, and the actual next-cycle seat bill is justified. Narrow the deployment if only one department or one owner gets value; reduce paid capacity where the workspace allows it, or compare an individual plan if collaboration is unnecessary. Cancel if outputs are too costly to verify, sensitive data cannot be handled under the required terms, or no staff member owns the process after the test.
Illustrative decision record: “Enquiry replies: pass after one prompt change. Meeting actions: pass. Invoice exception: fail, human check faster. Policy comparison: conditional, citations must improve. Event copy: pass. Admin access: pass after disabling an app. Paid seats next cycle: two Standard, $50 USD monthly list before local variation and tax. Decision: one more month, with three approved jobs and a review date.” That is stronger than “the team liked it”, because another manager can reproduce the decision.
Before cancellation or seat reduction, move approved work into the firm's normal records. OpenAI says a deactivated workspace stops member access, even though deactivation itself does not automatically delete the data. Removing a member frees their seat for reassignment but does not reduce the paid count. An owner must check the billing screen and schedule a reduction for the next cycle. The renewal procedure covers that handover and invoice check. Whatever the choice, preserve the test pack and scores so the next tool is judged against the same work.
Repeat the hardest passing task before committing
A single sample can pass by luck. Take the hardest job that met the first gate and test it on two more redacted cases with different wording. For the bookshop's enquiry replies, one case could ask for an unavailable title, another for a delayed special order. The approved policy may allow an estimated update date for the first and require supplier confirmation for the second. Ask a reviewer who did not write the prompt to check both. If that person cannot understand why the draft made its claims, the process is not ready for handover.
Record prompt version as well as output. An illustrative log might say: “Version 1 invented Friday collection; version 2 added an explicit rule to ask for confirmation; two follow-up cases passed; final reviewer took four and five minutes.” The improvement is evidence about this narrow task, not proof that every future customer message will pass. Put a stopping rule in the handover: if the source note lacks a confirmed date or price, the assistant may draft a request for clarification but must not offer a commitment. That rule gives staff a practical way to handle unfamiliar cases after the evaluation ends.
