What you're seeing
You're trying to make a change but the system won't let you, even though the invoice hasn't been exported. This can show up as any of these:
You can't edit an invoice — for example, adding materials or changing business units.
You can't edit job details such as the job date.
You can't complete a job.
You can't unapply a payment on an invoice.
Why this happens
Reason 1
The job or invoice date falls within a closed accounting period.
All of these point to the same cause: the job or invoice date falls within an accounting period that has been closed. ServiceTitan locks transactions in a closed period to protect your books, so edits stay blocked until the period is reopened.
How to fix it
1Reopen the accounting period
Use this to reopen the period that the job or invoice date falls in.
Before you start: You need the Open Period permission to reopen a closed accounting period. If you don't have it, contact your admin.
Note: Reopening a period does not reopen any transaction that was already exported to your accounting software. An exported transaction stays locked (the period shows as Partially Closed). If you change a record that has already been exported, make the same change in your accounting software too so your books stay in sync.
Go to the navigation bar and click Accounting.
In the side menu, click Accounting Periods.
On the Accounting Periods screen, find the period you need and click Actions > Open Period.
Confirm the period's status updates to Open.
✓ Done · The period is open, and you can now edit the invoice or job, complete the job, or unapply the payment.
Caution: When you're finished, close the period again to keep your books protected. Closing a period requires the Close Period permission, so this may be handled by your admin or accounting lead.
Still not working?
If the action is still blocked after reopening the period, contact ServiceTitan Technical Support at go.servicetitan.com/ask with:
The job or invoice number and its date
The accounting period you reopened and its current status
The specific action you're trying to take (edit invoice, edit job, complete job, or unapply payment)
Whether the invoice has been exported to your accounting software
