AI Month-End Close
and Reconciliation

Reconciliation, subledger tie-out, accruals, and intercompany netting run through the month. When the period ends, the close is already substantially done. Day 4, not day 15.

Key takeaways
  • The close is slow because it starts late. Almost every step waits for the period to end before anyone touches it.
  • Six steps carry most of the volume: bank reconciliation, subledger tie-out, accruals, intercompany, variance commentary, and board pack assembly.
  • Running those continuously turns the close into a review of exceptions rather than a rebuild from zero.
  • No ERP migration. ChatFin runs above NetSuite, SAP, JD Edwards, Dynamics 365, Acumatica, and Sage Intacct, and writes back as standard transactions.

Ask a controller why the close takes twelve days and the answer is rarely a single bottleneck. It is that nothing starts until day one. Bank statements get pulled, subledgers get tied out one account type at a time, accruals get calculated from a spreadsheet model, and intercompany waits on emails to entities in other time zones.

None of that work needs to wait for the period to end. Most of it could have been running all month, which is the whole idea behind a continuous close.

What runs before the period ends

Six close steps that do not need to wait. Each follows the same shape: the agent does the volume and drafts the result, a named person reviews the exceptions and approves.

01

Bank reconciliation, nightly rather than at period end

Pulling statements and matching a month of activity in the first days of the new period is the single largest block of manual work in most close calendars, and the least interesting.

How it runs

Bank feeds are matched to ledger entries every night across accounts and entities. By the time the period ends, almost the whole month is already reconciled and only the last days remain. Exceptions route to the accountant who owns the account, with the candidate matches and the reason attached.

Period end arrives with most of the month already matched, not with a queue to work through.
02

Subledger tie-out that catches breaks the day they happen

Payables, receivables, fixed assets, and inventory are reconciled to their control accounts once a month, which means a posting error can sit undiscovered for three weeks before anyone looks.

How it runs

Each subledger is tied to its control account daily. Differences surface within a day of the posting that caused them, while the person who made the entry still remembers the context. The month end tie-out becomes a confirmation rather than an investigation.

Found early, fixed cheaply. A break caught the next morning takes minutes. The same break found on day six takes hours.
All four ledgers at once. Payables, receivables, fixed assets, and inventory run in parallel rather than sequentially by owner.
03

Accruals staged before the period closes

Accrual models live in spreadsheets, open purchase orders get pulled by hand, and the reversal for next period is created from memory. It works, and it consumes days.

How it runs

Open purchase orders and recurring vendor commitments are monitored through the period. Accrual entries are drafted with the supporting detail attached and the reversal created alongside them, ready for controller review in the last week rather than the first week of the next month.

The controller reviews accruals instead of building them, with the PO behind each one.

Intercompany netted without the confirmation emails

Multi-entity groups spend days on confirmation emails and waiting for replies, and the group number stalls behind whichever entity answers last.

How it runs

Intercompany pairs are matched continuously across entities. Out of balance pairs are flagged with both legs and the difference, eliminating entries are drafted for review, and translation is applied at your rates. A three day sprint for a group of entities becomes an overnight run.

Variance commentary drafted from the actual drivers

The narrative is written last, under the most time pressure, which is why it so often repeats the prior month with new figures.

How it runs

Budget against actual is pulled from the ledger through the period and the material movements are decomposed by driver. The commentary is drafted in your house language with the supporting figures linked. The controller edits and approves rather than starting on a blank page on day three.

The narrative arrives as a draft with its numbers attached, ready to edit.

06

The board pack assembled as the close completes

Statements, commentary, KPIs, and supporting schedules get pulled together by hand at the end, which is why the pack lands a week after the numbers were final.

How it runs

The pack is assembled from live ledger data as each component is approved, so it is substantially complete by the time the last entry is signed. Every figure keeps its link back to the entries underneath, which is what makes a board question answerable in the meeting.

The pack is a byproduct of the close, not a separate week of work after it.

Your close does not need to be faster. It needs to start earlier.

The same close, a different shape

Nothing is skipped. The work simply stops being stacked into the ten days after the period ends.

From ERP connection to a running close

Four to six weeks, with the first cycle running in parallel to your existing process so nothing is at risk.

1

Map your close process

We audit your ERP, close calendar, and reconciliation inventory, and identify which steps are automatable and in what order.

2

Connect and configure the agents

ERP and bank connections are established through supported interfaces. Matching rules, accrual logic, and approval thresholds are set with your controller.

3

Run one cycle in parallel

The first automated reconciliation runs alongside your existing process so you can compare output against what your team produced before anything writes back.

4

Go live, then add entities

Agents take the volume, exception rates improve as the policy tightens, and new accounts and entities are added once the first close is trusted.

How ChatFin puts this into practice

Six close steps, one layer, on the ERP you already run.

ChatFin runs as the AI layer above your finance stack. Bank reconciliation, subledger tie-out, accruals, intercompany netting, variance commentary, and board pack assembly run through the period on NetSuite, SAP, JD Edwards, Dynamics 365, Acumatica, or Sage Intacct, with no migration required.

Results are written back as standard ERP transactions with the trail intact, so the ledger stays the system of record and the evidence is ready to pull rather than reconstructed at year end. See the full integration coverage if you want to check your stack first.

The teams closing on day four are not working harder. They are running the same work through the month instead of after it.
