Why ERP integrations are their own category
ERPs are the system of record for money and inventory, which raises the stakes. A bad sync here doesn't just annoy a salesperson — it ships the wrong stock or misstates the books. These integrations demand careful mapping and airtight error handling.
- Orders flowing from your storefront or app into the ERP
- Inventory and stock levels syncing back out to your sales channels
- Customers, vendors, and items kept consistent across systems
- Invoices, payments, and fulfillment status moving between finance and ops
- Nightly batch or near-real-time sync depending on the process
Working with real ERP APIs
ERP APIs range from modern REST to older SOAP and proprietary interfaces. NetSuite has SuiteTalk and REST; SAP and Dynamics have their own layers; some older on-prem ERPs offer only file exports or a database connection. We work with what your system actually exposes.
- NetSuite via SuiteTalk / REST and saved searches
- SAP, Microsoft Dynamics, Sage, Acumatica, and similar platforms
- Older ERPs with SOAP, flat-file (CSV/EDI), or direct DB access
- Respecting record locking, concurrency, and API governance limits
- Field and unit-of-measure mapping so quantities and codes line up
Protecting the system of record
Because the ERP holds financial and inventory truth, we build defensively: validate before writing, make operations idempotent so a retry can't double-post, and log every transaction so you can audit what synced and when.
- Validation and dry-run checks before writing to the ERP
- Idempotent writes so retries never duplicate an order or invoice
- Full transaction logging for audit and troubleshooting
- Staged rollout — read and report first, then writes, then two-way
- Alerting when a record fails to sync so nothing silently goes missing

Frequently asked questions
We're on NetSuite — can you connect it to our custom app?
Yes. NetSuite exposes SuiteTalk and a REST API plus saved searches, which we use to move orders, items, customers, and invoices between it and your app. We map your app's data model to NetSuite's records during discovery so the sync matches how your business actually works.
Our ERP is old and doesn't have a modern API — is it hopeless?
No. Plenty of older ERPs integrate through file exchange (CSV/EDI), a database connection, or a middleware layer we put in front. It's more work than a clean REST API, but it's a well-trodden path. We'll assess what your system exposes on a call.
How do we avoid breaking our accounting?
We start read-only, validate everything before any write, make writes idempotent, and log every transaction. Where possible we test against a sandbox ERP account first so nothing hits your live books until you've seen it work.
