What is TaxBridge?
TaxBridge is a unified API platform that lets software integrate with Pakistan tax authorities (PRA, FBR, KPRA, SRB) through one canonical invoice API and one developer experience.
What is a tax API?
A tax API lets your software submit invoices electronically to a tax authority and receive a verifiable fiscal invoice number and QR value in response, instead of manual filing.
What is PRA API integration?
Connecting your software to the Punjab Revenue Authority so services invoices in Punjab are filed electronically. With TaxBridge you integrate once and TaxBridge handles PRA’s format and credentials.
What is FBR API integration?
Connecting your software to the Federal Board of Revenue for sales tax on goods, so each invoice is filed and returns an FBR invoice number and QR. TaxBridge normalizes FBR’s success rules for you.
Can I integrate my existing POS?
Yes. TaxBridge is an API layer you call from your existing POS at the moment a sale is finalised — no rip-and-replace.
Can I integrate my ERP?
Yes. Your ERP calls one canonical invoice API when it posts a sales document, and TaxBridge files it with the right authority.
Does TaxBridge support PRA, FBR, KPRA and SRB?
Yes — all four, behind the same endpoint, with more authorities addable without a client code change.
Is sandbox testing available?
Yes. Sandbox and a built-in simulator are included on every plan so you can build before you hold real credentials.
Is production available?
Yes. After approval you activate production, store real credentials and issue live keys. Sandbox and production stay fully separate.
Do I need to integrate each authority separately?
No. You integrate once against the canonical invoice shape; TaxBridge routes to the correct authority.
How long does integration take?
A prepared team can reach a working sandbox integration in about two hours. Real go-live depends on your architecture, invoice workflow, credentials and tax-authority requirements.
Can I test before purchasing?
Yes. Build and test in the sandbox with the simulator before choosing a plan.
Can I manage multiple companies and branches?
Yes. Manage many companies and branches under one account, each with isolated credentials and quota.
How do API credentials work?
Authority credentials are stored encrypted and never returned. API keys are scoped to an environment and shown once, then stored as a hash.
How are errors handled?
Errors are normalized into one vocabulary across all authorities, with a readable message and, for validation, the exact fields at fault.
Can I see API logs?
Yes. Full request/response logs and usage analytics are in the dashboard.
How can I monitor API usage?
Usage dashboards show consumption against quota, and every API response includes a quota object; alerts warn you before the cap.
Can SaaS, restaurant, retail and accounting software use TaxBridge?
Yes — any software that produces a sales invoice can integrate: SaaS platforms, restaurant and retail POS, accounting and ERP systems, and e-commerce.
Do I need to change my existing POS?
No. You add one API call at the point of sale; the rest of your POS is unchanged.
How do I move from sandbox to production?
Complete company/branch configuration and production credentials, get approved, then generate a live key and switch your endpoint.
What happens if a tax authority API changes?
TaxBridge absorbs authority-side changes in its integration layer, so your canonical payload and response envelope stay stable.
Who provides technical support?
