Custom or Client ERP Integrations & Connectors
Connect any custom, homegrown, or unsupported ERP with 40+ business tools via REST APIs, CSV/Sheets sync, or middleware bridges (Zapier, n8n, Make).
About Custom or Client ERP
Not every Indian business runs on TallyPrime, Zoho, SAP, or Odoo. Family businesses often run homegrown ERPs built in FoxPro, MS Access, or custom .NET stacks. Mid-market manufacturers frequently rely on vertical-specific systems from Oracle, Microsoft Dynamics, IFS, or in-house teams. ERPPlugs's Custom ERP integration is designed for these cases — a flexible bridge that connects any ERP to WhatsApp, payment gateways, marketplaces, shipping partners, and analytics tools without requiring your ERP vendor to build or approve anything. Three integration modes cover the full spectrum: a REST API + webhook bridge for ERPs with programmable interfaces, a scheduled CSV or Google Sheets sync for legacy systems with export-only capability, and a middleware bridge through Zapier, n8n, or Make for any ERP that already speaks to one of those platforms. Perimattic's solutions team handles the initial mapping and validates that data flows accurately in both directions before the connector goes live.
