Closing the month in AP means making sure every bill for the month is entered, approved and coded and the payables balance ties out.

What to watch in Sage X3
- Start in Financials > Invoices > Purchase invoices. You need function and site rights for the screen.
- Run Invoice validation for all saved and checked purchase invoices before anything else.
- A posted invoice can no longer be modified. Use a reclass journal entry for a coding fix.
- Invoice validation is described in the vendor help for version 12. Confirm the period close steps with your partner before you rely on them.
- Close the accounting period only after the AP control account is reconciled.
The Pulsify way
- Clear the Pulsify queue: approve, reject or archive each bill waiting.
- Forward missing bills from suppliers to your Pulsify address.
- Reconcile key supplier statements in Pulsify.
- Then run reports and lock the period in Sage X3.

Example in Sage X3
Example Pty Ltd closes September in Sage X3. Some purchase invoices were saved and checked in the last week but never validated.
| Line | Amount | Tagged to |
|---|---|---|
| Saved and checked purchase invoices, not validated | $18,400.00 | Run Invoice validation |
| Payments posted in the month | $52,000.00 | Post payments |
| AP control account, difference after validation | $0.00 | Reconcile before you close the period |
After Invoice validation the AP control account agrees. The period is closed. A posted invoice can no longer be modified, so a late coding fix goes through a reclass journal entry.
Common mistakes
- Closing the period with saved invoices not yet validated.
- Not reconciling the AP control account before close.
