Bulk changing account codes means moving many bills or lines from one account to another in one go, usually after finding a coding mistake.
Before you start
- Sage 300 Accounts Payable
- A/P security authorisation for the screen
The Sage 300 way
Where to find it: Accounts Payable > A/P Transactions
- Edit an unposted invoice batch in A/P Invoice Entry and change the G/L account on the detail lines before you post.
- To correct a posted invoice, enter an adjustment in A/P Adjustment Entry. Adjustment batches hold corrections to posted transactions.
- To change many vendor records at once, export the vendor records to a spreadsheet, edit them and import them back (the guide gives the example of changing the tax group).
Limits in Sage 300
- No screen was found that changes the account code on many posted bills in one go.
- Posted invoices are corrected with adjustment entries, one document at a time.
Words Sage 300 uses
- Batch. A group of invoices entered together and then posted together.
The Pulsify way
- Fix the account in Pulsify before approval. Pulsify learns from corrections, so later bills for that vendor follow the new account.
- For bills already in Sage 300, make the change in Sage 300.

What Pulsify does not do here
- Pulsify does not recode bills that are already in Sage 300.
- Pulsify cannot edit locked periods. Use a journal in Sage 300.
Common mistakes
- Treating a vendor export and import as a way to fix posted invoices. It changes vendor records, not posted documents.
- Editing unposted lines in Invoice Entry when the batch has already been posted.

Common questions
Can I change the account on a posted Sage 300 invoice?
Not in place. Posted invoices are corrected with an entry in A/P Adjustment Entry, one document at a time. An unposted batch can be edited in A/P Invoice Entry before you post.
Is there a bulk recode screen?
No screen was found that changes the account code on many posted invoices in one go. For vendor records you can export to a spreadsheet, edit and import back, as the guide does for the tax group.
What is an adjustment batch?
Adjustment batches hold corrections to posted transactions. You enter them in A/P Adjustment Entry.
Does Pulsify recode old bills?
No. Pulsify codes bills before they reach your accounting system. Past bills are changed in your accounting system.
