Review recurring costs connected to an AI writing workflow by inventorying every seat, subscription, usage charge, retrieval service, storage account, integration, monitoring tool, and human-review hour, then connecting each cost to accepted outputs. Count failed drafts, rework, source research, and approval time as well as generation. Do not cancel a shared service until its data, owners, dependencies, and retention duties are known.
Build the cost map
Record provider, plan, account owner, renewal date, billing unit, current quantity, commitment, data location, and the workflow step supported. Separate fixed seats from variable usage and shared services. Allocate shared costs with a documented method such as active users, accepted documents, or measured requests.
Include reviewer and editor time, training, policy maintenance, incident handling, source subscriptions, exports, and manual fallback. NIST's AI RMF Core says expected benefits and costs, including non-monetary costs from errors or system behavior, should be examined and documented against organizational risk tolerance (NIST AI RMF Core).
Measure use and accepted output
Choose a representative period and count active users, runs, accepted documents, rejected drafts, corrections, sourced claims, and published or delivered outputs. Calculate cost per accepted output, not cost per generation. Add the time spent finding evidence and correcting unsupported statements.
When a writing tool is bundled into a broader suite, use available administrator usage reports rather than assuming every assigned seat is active. Microsoft says its Microsoft 365 usage reports can show who uses a service heavily or barely uses it and might not need a license (Microsoft 365 usage reports). Use the equivalent report for the actual service and respect its reporting delay.
Review alternatives and risk
Mark duplicate subscriptions, unused seats, premium features without a supported need, personal accounts funding team work, and integrations with no owner. Compare resizing, consolidating, replacing, or returning a narrow task to a manual process. Include export limits, retraining, lost source access, privacy changes, and the cost of revalidating the workflow.
Do not optimize by removing human review from consequential content or by sending private data to a cheaper service. A lower invoice can create higher rework, legal, security, or reputational cost.
Record and verify decisions
For each line item, record keep, resize, consolidate, replace, or investigate; the evidence; expected saving; one-time change cost; owner; approver; and next review. Verify any saving on the next invoice and confirm accepted-output quality after the change.
The review is complete when every recurring cost has an owner and workflow link, usage covers a representative period, human effort and rework are counted, and realized savings are distinguished from estimates. Otherwise label the result preliminary.
