How do I set the GL Posting Date for invoices synced to Sage Intacct?
Control which accounting period your AP bills land in by setting a custom GL posting date on the invoice form.
The GL Posting Date field lets you control the accounting period an invoice posts into when it syncs to Sage Intacct. This is useful when you need to key in an invoice in one month but have it post to a different period — for example, entering a September invoice that should appear in August's books.
Where to find it
The GL Posting Date field appears on the invoice form (New Invoice, Edit Invoice, and the OCR Review Document screen) for companies connected to Sage Intacct.
To set a GL posting date:
-
Open an invoice or create a new one
-
Look for the GL Posting Date field in the dates section, below Issue Date and Due Date
-
Click to select the date you want the bill to post on
-
Save the invoice
Note: If you leave the field blank, ProcurementExpress will automatically use the invoice's approval date (or the issue date if never approved) as the GL posting date — this is the same behaviour as before this feature was added.
Viewing the GL posting date
Once set, the GL Posting Date displays on the invoice detail page alongside the other dates (Issue Date, Due Date).
If no date was explicitly set, the page shows the date the bill will post on in muted text: "Not set — will post on 02/09/2026".
Adding GL Posting Date to the invoice listing
The GL Posting Date is available as an optional column on the invoice listing. It's hidden by default.
To add the column:
-
Go to your Invoice Listing page
-
Click the column picker (gear icon)

-
Tick GL Posting Date
-
Save your preferences
The column will show the posting date, or the derived date in muted text when no explicit date was set.
Exporting GL Posting Date
When you export your invoice listing, the GL Posting Date column will be included if you've selected it. The export shows the effective posting date — either the date you set or the derived date (approval date / issue date fallback).
Important notes
- Sage Intacct setting required: Your Sage Intacct account must have Enable override of GL posting date during entry turned on in Configure Accounts Payable → Screen settings. Without this, Sage may ignore the date you send.
- Backdating is allowed: Unlike other date fields, the GL Posting Date intentionally accepts dates before the issue date — backdating into an earlier period is the entire point of this field.
- Locked after payment: Once Sage Intacct marks the bill as Paid or Partially Paid, the GL Posting Date becomes read-only. You'll see an explanatory tooltip if you try to edit it.
- Closed period errors: If you pick a date in a closed accounting period, Sage will reject the bill. The error message will tell you which date was rejected so you can pick one in an open period.
