Costing an AI project – the items people usually miss
When budgeting for AI, many businesses only count the tool subscription. In reality there are at least five cost groups.
| Cost group | What's included | Often overlooked |
|---|---|---|
| Tool | Per-user subscription fees, usage-based fees (API) | Fees that grow as usage grows |
| Data preparation | Collecting, cleaning and rewriting documents | Time from staff who know the business |
| Implementation | Building workflows, connecting software, testing | Time to test with real situations |
| Training | User onboarding and documentation | Retraining when new people join |
| Operations | Monitoring, fixing errors, updating documents | Someone responsible after handover |
How to estimate the benefit
Take the hours a task consumes each month, multiply by the hourly staff cost, then estimate the share AI could cut. Be cautious: assume a low reduction the first time, measure reality after the pilot, then adjust.
How to keep costs under control
- Start with one task and one small team.
- Set a monthly spending cap for usage-based tools.
- Review the list of accounts every quarter and cancel plans nobody uses.
- Only scale up when the numbers show it works.
