FBR software must work on sandbox before you trust live
Digital invoicing fails when teams only see a PDF. A free 1-month AsanInvoice trial walks GST/SST create → payload preview → FBR sandbox submit → Invoice ID status so finance verifies the API path before production.
AsanInvoice is multi-company SaaS with roles, branded PDFs and SMTP — built for Pakistani tax-registered businesses.
What finance should verify in 30 days
Company isolation, invoice prefixes, NTN/STRN on PDFs, sandbox vs live environment switching, and whether submitted invoices lock correctly. Bring NTN/STRN and monthly invoice volume to the trial kickoff.
Pair the trial with our FBR digital invoicing guide so your checklist matches what GSC buyers search for.
