Closing the month in AP means making sure every bill for the month is entered, approved and coded and the payables balance ties out.
Before you start
- Posting period authorisation
The SAP B1 way
Where to find it: Administration > System Initialization > Posting Periods
- Clear open items.
- Reconcile A/P to the G/L.
- Set the posting period status. Use the status that still lets people post late A/P invoices until you are done, then Period Closing, then Locked.
Limits in SAP B1
- One status stops sales documents but allows other documents and A/P invoices.
- Locked means nothing can be posted.
- Archived periods are set by the archive wizard.
Words SAP B1 uses
- Posting period. A date range that can be opened or closed for posting.
The Pulsify way
- Clear the Pulsify queue: approve, reject or archive each bill waiting.

Common questions
Which posting period status keeps A/P open for late invoices?
SAP has a status that stops sales documents but still allows other documents and A/P invoices. Use it while late supplier invoices come in.
What does Locked do?
Nothing can be posted. Use it only after A/P is reconciled to the G/L and the late invoices are in.
Where do I set the status?
Administration > System Initialization > Posting Periods. You need posting period authorisation to change it.
Does Pulsify lock periods?
No. Lock the period in your accounting system.
