ERP integration is one of those tasks that sounds simple but quickly gets complex. Between mapping fields, handling errors, and keeping data in sync, it's easy to lose hours every week. Here are five practical tricks we've learned from building hundreds of integrations.
1. Use Webhooks, Not Polling
Polling your ERP every 5 minutes for updates is wasteful. Most modern ERPs — including ERPNext — support webhooks that push changes to your system in real time. This cuts latency from minutes to seconds and reduces API load by 90%.
2. Batch Your Updates
Instead of updating one record at a time, batch them. Send 100 inventory updates in a single API call instead of 100 separate calls. This alone can reduce sync time by 60-70%.
3. Cache Read-Heavy Data
Product catalogs, customer lists, and price tables don't change every second. Cache them locally and refresh periodically. This eliminates redundant API calls and makes your system feel instant.
4. Use Field Mapping Templates
Don't re-map fields for every integration. Create reusable mapping templates for common ERP entities — customers, products, orders, invoices. OnWebApp's integration module includes pre-built templates for ERPNext, SAP, and Oracle.
5. Monitor and Alert
Set up alerts for failed syncs, slow responses, and data mismatches. OnWebApp's monitoring dashboard tracks every API call and notifies you before small issues become big problems.
Implementing these five strategies typically cuts ERP integration time from weeks to days. Need help? Our integration architects offer a free 30-minute consultation to map your data landscape.
