ERP and eCommerce integration that keeps stock, orders, and pricing honest.
If your team re-keys orders, exports CSVs, or fixes stock counts by hand, the fix is an integration — built with idempotent writes, retries, and monitoring so it doesn't become the next thing you babysit. Reed Dynamic builds that middleware from Ann Arbor, Michigan.
ERP eCommerce integration connects your online store (Magento 2, Shopify, WooCommerce, BigCommerce) to your ERP or WMS (NetSuite, Acumatica, Epicor Prophet 21, SAP Business One, Dynamics) so products, inventory, pricing, orders, invoices, and customers stay in sync automatically. Reed Dynamic builds these integrations for $5,000–$75,000 with monitoring included; one recent WMS integration cut fulfillment errors 85%.

How we build integrations that don't break
Map every system and field
Including the spreadsheets nobody admits are load-bearing.
Decide the source of truth per field
Price lives in the ERP; web copy lives in the store; stock lives in the WMS. Ambiguity here is why integrations fail.
Design sync cadence per entity
Webhooks for orders and stock; batches for catalog.
Build idempotent, retried, queued
Every write is safe to repeat; failures land in a dead-letter queue with context.
Instrument and document
Dashboard, alerts, runbook. The next engineer isn't guessing.

★★★★★
“This case was so complex that we didn’t know if the integration was even possible. They found a way to make it work. They have a craving for knowledge which was a real asset for us.”

Build vs. iPaaS connector
| iPaaS connector (Celigo, Boomi, etc.) | Custom middleware (Reed Dynamic) | |
|---|---|---|
| Upfront cost | Low | $5k–$75k |
| Recurring cost | Per-connection / per-transaction fees forever | Hosting + optional support retainer |
| Custom pricing, bundles, multi-warehouse | Often limited or extra | Built to your model |
| Legacy / undocumented systems | Usually unsupported | Reverse-engineered as needed |
| Ownership | Vendor-hosted | Your code, your accounts |
| Best for | Standard mappings between mainstream systems | Anything with business logic or a legacy system |
ERP & integration FAQs
How much does an ERP to eCommerce integration cost?
Point-to-point integrations start around $5,000. Full middleware syncing products, inventory, pricing, orders, invoices, and customers between an ERP and a storefront typically runs $20,000–$75,000 depending on entities, volume, and how well-documented the ERP's API is. See pricing.
Which ERPs do you integrate?
NetSuite, Acumatica, SAP Business One, Epicor Prophet 21, Microsoft Dynamics 365 / Business Central, QuickBooks Enterprise, and custom or legacy ERPs via database, flat-file, or EDI. On the storefront side: Magento 2, Shopify, WooCommerce, BigCommerce, and custom carts. Read about our Epicor Prophet 21 work.
Should we use an iPaaS like Celigo or build custom middleware?
An iPaaS connector is fine when both systems are mainstream and your mapping is standard. Custom middleware wins when you have customer-specific pricing, complex product structures, multiple warehouses, legacy systems without connectors, or when the per-transaction iPaaS fees exceed the build cost within a couple of years. We'll recommend either honestly.
How do you keep integrations from silently failing?
Idempotent writes, retries with backoff, a dead-letter queue for records that can't sync, and a monitoring dashboard with alerting — so the ops team sees a failure within minutes, not when a customer calls. This is how a recent WMS integration cut fulfillment errors by 85%.
Real-time or batch sync?
Inventory and order status usually need near-real-time (webhooks or short polling). Product and pricing updates are often fine in batches. We design per entity, based on how stale each field is allowed to be.
Do you integrate CRMs like Salesforce and HubSpot?
Yes. Our verified Clutch review is for a HubSpot + Salesforce + CloudCraze commerce integration — a project the client didn't know was possible until we shipped it. Read it on the Work page.
