Quick Answer
The third quarter close should leave banks, CFDI, accounts receivable, inventory, assets, payroll, and taxes reconciled or with a plan. Do it before September 30 to correct differences and project cash flow and ISR in time, not during the annual close.
Use the third quarter close to reconcile banks, CFDI, accounts receivable, inventory, payroll, taxes, and annual projection.
Don’t Mask the Close
An unresolved difference must remain open with an explanation; do not hide it with a global adjustment.
Ten Days Before Close
- Banks and payment gateways reconciled.
- CFDI issued, received, and canceled.
- Accounts receivable, suppliers, and taxes.
- Inventory, assets, and payroll.
- Losses, provisional payments, and annual projection.

Q3 Pre-Close Plan
- Freeze scope and materiality.
- Reconcile critical sources.
- Investigate open items.
- Project tax and cash flow.
- Present decisions and follow-up.
September close starts before the 30th
By mid-September, finance identifies old accounts receivable, inventory without count, and assets without custody. Assign responsible parties and deadlines before the cutoff. At quarter-end, only update final movements and document approved adjustments.
A preventive close turns the last month into confirmation, not a search for nine months’ worth of documents.

Why September is a Control Point
The third quarter allows correcting differences before the annual close. The review should combine operations, accounting, and tax: banks, CFDI, accounts receivable, inventory, payroll, taxes, and files.
It’s not about submitting an early annual close, but identifying items that still have time to be resolved and estimating cash and tax with better data.
What Makes a Pre-Close Useless
- Waiting for the annual close.
- Adjusting without evidence.
- Ignoring repeated small items.
- Not assigning responsible parties and deadlines for findings.
