How Validation Works

Two simple steps to validate your invoices.

Paste your invoice data

Copy your invoice JSON from Xero, QuickBooks, or any accounting system and paste it into the sandbox above.

See real-time validation results

TaxConnect checks your invoice against the FBR schema and PRAL sandbox, returning detailed validation results instantly.

Why Validate First

Avoid common pitfalls with pre-submission validation.

Catch Errors Early

Validate your invoice JSON against the FBR schema before submission. No more rejected invoices or compliance notices.

No Risk

Test in a sandbox environment that mirrors the real PRAL system. Your data never touches the production FBR infrastructure.

Build Confidence
