ERP GST Integration

Generic integration pattern for any ERP — Oracle EBS, NetSuite, Odoo, Microsoft Dynamics, or a custom in-house system. Uses the same OAuth 2.0 + REST + JSON surface as our SAP and Tally connectors, just without the pre-packaged add-on.

Data mapping cheat sheet

WhiteBooks field	ERP source (typical)
`SellerDtls.Gstin`	Company master record GSTIN
`BuyerDtls.Gstin`	Customer master GSTIN
`DocDtls.No`	Invoice number (must be unique within FY)
`DocDtls.Dt`	Invoice posting date (DD/MM/YYYY)
`ItemList`	Invoice line items (qty, unit price, HSN, GST rates)
`ValDtls`	Computed totals (assessable, tax, grand total)

Reference implementations

We have customers running this pattern on: Oracle EBS, Oracle Fusion Cloud, NetSuite, Microsoft Dynamics 365 Business Central, Odoo, Sage, Zoho Books, custom Spring Boot ERPs, custom Django ERPs. The integration ships in 2–4 sprints for a typical mid-market ERP.

FAQs

Who uses WhiteBooks for Enterprise / ERP workflows?

Custom or boutique ERPs need GST + e-Invoice integration without a vendor-specific connector. WhiteBooks handles this via OAuth 2.0 REST APIs, first-party SDKs in Java / Node / Python, and pre-built connectors for SAP / Oracle / Dynamics / Tally.

How long does integration take?

Typical timelines: 1–2 sprints for SaaS / fintech integrations on the raw REST API; 3–5 weeks for Tally-connector deployments; 4–8 weeks for SAP / Oracle full integrations.

Sandbox?

Yes — apisandbox.whitebooks.in/{product} mirrors the production schema with a sample GSTIN. Free.

Does it support KSA ZATCA?

Yes — WhiteBooks ships a dedicated KSA e-Invoice API for businesses with Saudi Arabia operations. See /api/ksa-e-invoice-api-for-developers.

Pricing?

Annual plans from Custom pricing (Starter, 1,000 IRN/month) → Custom enterprise pricing/year (Enterprise, unlimited). Free sandbox. See /about/pricing.
