VATCalc Calculator vs Zamp

VATCalc Calculator determines VAT and GST for domestic and cross-border transactions, either as transactions occur or in batches. It can connect to shopping carts, ERPs, ecommerce platforms, invoicing systems, and other applications through web access and an API. Calculations draw on codified national tax laws, including the EU VAT Directive, and can include legal references and suggested adjustments. Users can map goods and services themselves, use pre-mapped HS, TARIC, and CPA codes, or apply coding assumptions with VATScript. Customer-selected exchange-rate data can be incorporated.

The product supports REST API feeds, HTTP, FTP, and other exchange formats. Listed integrations include SAP S/4HANA and ECC, SAP Public Cloud, Oracle NetSuite, Oracle JD Edwards, Odoo, and Chargebee. Transactions can flow into VAT returns through the shared VAT Filer platform, and the calculator can also be incorporated into VATCalc’s e-invoicing service. VATCalc describes the service as built on Amazon Web Services to handle transaction volumes and daily peaks without latency planning. It states that it is ISO 27001 certified. Pricing is on request, and a free trial is available.
