Where AI actually helps
AI takes the most time out of the close on high-volume, pattern-based work: coding transactions, matching them in reconciliations, and drafting first-pass variance commentary. Teams using it well report taking days, not hours, off the calendar - because the machine handles the repetitive 80% and people spend their time on the 20% that needs judgment.
| Close task | What AI does well | What still needs you |
|---|---|---|
| Transaction coding | Suggest categories from history | Approve the edge cases |
| Reconciliations | Match the routine items | Investigate the breaks |
| Flux commentary | Draft the first explanation | Add the business context |
| Accruals and judgment | Flag what looks unusual | Decide the treatment |
Where it does not (yet)
AI is fast at the work that follows rules. The close still lives or dies on the judgment calls - accruals, unusual transactions, and whether the numbers actually make sense.
Accrual decisions, one-off transactions, revenue cut-off, and anything touching estimates still need a person who understands the business. So do controls: a close that no human reviews is a control gap, not an efficiency win. The goal is augmentation - AI drafts and matches, a controller reviews and signs off.
A realistic close timeline
Used well, AI compresses the front half of the close - the data wrangling - so review starts sooner:
- Days 1-2: AI codes transactions and runs first-pass reconciliations; the team clears exceptions.
- Days 2-3: AI drafts flux commentary; the controller adds context and reviews accruals.
- Day 3-4: sign-off and reporting - earlier than a manual close that often runs 5-7 days.
How to adopt it safely
- Start with one task - usually transaction coding - and measure the time saved before expanding.
- Keep a human in the loop on every output; AI drafts, a person approves.
- Document the workflow in your close calendar so the process is repeatable and auditable.
- Preserve the audit trail - record what AI suggested, who reviewed it, and what changed.
