SAP B1 ↔ Avalara AvaTax — US Sales Tax + VAT Automation
The SAP Business One ↔ Avalara AvaTax connector by ERPPlugs calls Avalara for real-time tax determination on every B1 Sales Order + AR Invoice + Credit Memo — US sales tax, EU + UK VAT, Canadian GST/HST, and Marketplace Facilitator scenarios. Nexus data flows from Avalara; compliance filings run through Avalara Returns.
Real-time Avalara AvaTax on every SAP B1 Sales Order + Invoice + Credit Memo — US sales tax, VAT, GST, MPF handled centrally.
What this connector does
Avalara AvaTax is the standard tax-determination platform for US SMB + mid-market — real-time rate calculation for US sales tax + EU/UK VAT + Canadian GST/HST + 200+ other jurisdictions. Managing tax tables inside SAP B1 doesn't scale past 3-4 nexus states; Avalara maintains rates centrally so B1 never touches tax-table maintenance. The ERPPlugs SAP B1 ↔ Avalara connector uses AvaTax REST + SAP B1 Service Layer to call AvaTax on every SO/Invoice/Credit Memo, apply the returned tax, and feed committed transactions to Avalara Returns for compliance filing.

Frequently Asked Questions
B1 native tax tables need per-jurisdiction maintenance and don't scale past 3-4 states. Avalara maintains rates for 12,000+ US jurisdictions centrally with monthly updates. For any US SMB with nexus in 5+ states, Avalara pays for itself in tax-table maintenance time alone.
For states + jurisdictions where marketplaces (Amazon, eBay, Walmart) collect tax as MPF, Avalara applies MPF logic on marketplace-sourced revenue so your own returns reflect only own-collected tax.
Avalara CertCapture manages exemption certificates centrally. When an exempt customer's BP is used on an SO, the connector applies the exemption automatically (no tax charged) and preserves the certificate reference for audit.
Avalara normalises ship-to addresses before rate determination so per-zip-code + per-local-jurisdiction tax is correct. Malformed addresses flag for correction before the SO commits.
Yes — EU + UK + Canadian VAT/GST all through the same Avalara call. VAT MOSS for digital services, reverse-charge for B2B EU, and Canadian GST/HST/PST all handled per jurisdiction.
