ERP integration
Connect SAP to FBR without a multi-year custom build
For finance and IT teams running SAP who need digital invoicing. Keep SAP as the source of truth — add a dedicated submission layer for FBR.
Architecture choice
Custom SAP FBR module vs ready API layer
ABAP-heavy FBR builds feel controlled until the next technical specification change.
Custom Z-module / direct gateway
- Scarce SAP developers tied up on FBR schema work
- Every FBR update becomes a transport and regression cycle
- Retries, bulk, and idempotency often under-designed
- Harder to reuse the same path for non-SAP channels later
SAP → eInvoicePro → FBR
- SAP keeps commercial truth; API handles FBR-specific validation
- One place to update when FBR technical specs change
- Status polling and proof storage outside core ERP customizing
- Finance and IT can work in parallel with product demos and developer docs
Project ownership
Who does what
Align these roles before interface development starts.
Finance / controlling
Invoice types, tax codes, buyer validation rules, and sign-off on sandbox cases that mirror real revenue.
SAP / IT team
Interface from SAP to eInvoicePro, environment management, monitoring, and error handling.
Tax advisor
Compliance scope, gateway path, and penalty exposure — not replaced by software vendors.
FAQ
Frequently Asked Questions
Can SAP send invoices directly to FBR?
SAP can be configured to send invoice data to middleware like eInvoicePro, which handles FBR validation, submission, and responses through your approved FBR path. Most teams avoid rebuilding every FBR rule entirely inside SAP customizations.
Who owns the SAP integration project?
Finance owns tax treatment and invoice correctness. IT owns SAP configuration, interfaces, and environments. Your tax advisor covers compliance scope. eInvoicePro helps with the product and API layer — not tax advice.
Do we need to replace SAP?
No. The goal is to keep SAP as your system of record and add a reliable FBR submission path alongside it.
What interface patterns work?
Common patterns include API calls from middleware, scheduled extracts, or message-based interfaces after billing. Exact design depends on your SAP landscape (ECC vs S/4), invoice volume, and whether you need near real-time or batched submission.
