FBR STGO 01 of 2026: Invoice Amendment, Cancellation & the 72-Hour Rule
FBR's Sales Tax General Order (STGO) No. 01 of 2026 clarifies how the mandatory e-invoicing regime works in practice — how long you have to correct an e-invoice, when the Commissioner's approval is needed, and that a business may engage more than one licensed integrator. Here is what it means for your invoicing.
What STGO 01 of 2026 is
A Sales Tax General Order (STGO) is an operational clarification FBR issues to explain how an existing rule should be applied. STGO No. 01 of 2026 does not create a new obligation to integrate — that obligation already exists under SRO 1413(I)/2025, SRO 709(I)/2025 and the revised schedule in SRO 1852(I)/2025 — but it settles practical questions about how registered persons issue, correct and manage their electronic sales tax invoices.
The two clarifications that matter most for day-to-day billing are the time window for amending or cancelling an e-invoice, and confirmation that a business is free to work with more than one licensed integrator.
The 72-hour amendment and cancellation window
Under the order, an electronic sales tax invoice can be amended, cancelled or deleted through the FBR system within 72 hours of its issuance without any prior approval. This gives businesses a short, self-service window to fix genuine mistakes — a wrong quantity, an incorrect buyer, a mis-selected sale type — before the invoice is locked in.
After 72 hours the invoice is treated as final: any change then requires approval from the Commissioner Inland Revenue, and FBR has separately tightened the surrounding controls (for example limiting how many times an item may be edited and moving finalised invoices into the sales tax return). The practical takeaway is to review and correct invoices quickly, ideally the same day they are posted.
You can engage more than one licensed integrator
STGO 01 of 2026 expressly allows a registered person to engage multiple licensed integrators at the same time, while reporting stays centralised with FBR. That means you are not locked into a single vendor: different outlets, business lines or systems can each connect through the integrator that suits them, and you can add or switch integrators without losing your FBR integration.
For most small and mid-size businesses one PRAL-certified integration is enough, but the flexibility is useful for groups running different POS or ERP systems across locations.
What this means if you use Digi Invoice
Digi Invoice posts each sales tax invoice to the FBR DI API v1.12 and stores it in a built-in ledger, so the invoices you can correct in the 72-hour window are exactly the ones already recorded against your FBR profile. Keeping billing in one place makes it easy to spot and fix an error before the window closes.
Full self-service edit and cancel inside the app, mirroring the IRIS cancellation screen, is a compliance feature FBR provides natively on iris.fbr.gov.pk today; if you need to cancel a posted invoice right now, do it there. Always confirm the current amendment rules on the official FBR portal, because operational orders like this can be updated.
