Zapier and your ERP: fast automations, sensible limits
Zapier connects thousands of apps without code. For low-volume tasks — a web form creating a lead, a new customer posting to Slack, a signed contract updating a record — it is the fastest route to automation.
Overview
What this integration is for
It is not the right tool for high-volume order sync or anything where a missed or duplicated record costs money. We help you use Zapier where it fits and build proper integrations where it does not.
01Data
What data syncs, and in which direction
| Entity | Direction | Notes |
|---|---|---|
| Leads & contacts | App → ERP | Form tools, ad platforms and calendars creating leads or contacts. |
| Notifications | ERP → App | New orders, overdue invoices or tickets posted to chat or email tools. |
| Simple records | ⇄ Both | Low-volume updates such as tasks, notes or status changes. |
02Use cases
Common use cases
01
Lead capture
Forms and ad leads straight into ERP CRM.
02
Team alerts
Important ERP events posted to Slack or Teams.
03
Prototyping
Prove an automation before investing in a custom integration.
03 — Architecture
API architecture
Zaps call the ERP through its API or a webhook endpoint. For anything business-critical we add a small receiving endpoint in the ERP that validates input and logs every call, instead of writing directly to records.
04Reliability
Authentication, errors and retries
01
Authentication
A dedicated ERP API user with minimal rights, so a misconfigured Zap cannot change data it should not touch.
02
Error handling
Zapier task history shows failures; critical Zaps also notify a channel on error. ERP-side logs record every request.
03
Retry strategy
Zapier's built-in replay for failed tasks, used together with idempotent ERP endpoints.
05 — Data mapping
Field mapping essentials
| Zapier | ERP |
|---|---|
| Form fields | Lead fields |
| Event type | Notification channel |
06 — Automation
Automation opportunities
- Website or ad leads created in CRM with source tracking
- Won deals posted to a sales channel
- Overdue invoice reminders to account managers
07 — Security
Security considerations
Least-privilege API credentials, no sensitive data passed through Zaps unnecessarily, and a list of who owns each Zap.

FAQ
Frequently asked questions
Can Zapier sync our web shop orders?
For a handful of orders a day it can, but missed or duplicated orders are costly. A proper integration with retries and reconciliation is safer at volume.
Does Zapier work with Odoo and ERPNext?
Yes, through their APIs or webhooks, and through available Zapier apps where they exist.
