Selling an item you don't have, or re-typing every order into the ERP, costs money and customers. Integration fixes both.
Codersarts ERP and inventory integration connects your store to the systems that run your operations, with monitoring so problems surface before customers notice.
What Is Ecommerce ERP Integration?
Ecommerce ERP integration connects an online store with enterprise resource planning (ERP), inventory, warehouse (WMS) and shipping systems. It syncs products, stock levels and prices from the ERP to the store, sends orders and customers from the store to the ERP, and returns fulfillment, tracking and invoice data, often across several sales channels.
Who This Is For
Brands selling on several channels
Retailers with physical and online stock
Distributors with B2B and B2C stores
Stores using 3PL warehouses
Teams re-keying orders by hand
What We Integrate
Products and prices
Catalog and price lists from the ERP.
Stock levels
Near real-time stock across warehouses and channels.
Orders
Orders, customers and payments into the ERP.
Fulfillment and tracking
Shipping status and tracking back to customers.
Invoices and returns
Invoices, credit notes and returns.
Marketplaces
Amazon, Flipkart and other channels from one stock pool.
Reliability
Queues, retries and alerts. See message queues.
Integration Approaches
Approach | Best for | Trade-offs |
|---|---|---|
Ready-made connector | Common ERP and platform pairs | Limited custom logic |
Integration platform (iPaaS) | Several systems and channels | Monthly cost |
Custom integration | Unique rules or older ERPs | Built and maintained by you |
Common Integration Problems We Fix
Problem | Usual cause | Fix |
|---|---|---|
Overselling | Slow or failed stock sync | |
Orders missing in ERP | No retries or alerts | |
Duplicate orders | No idempotency | |
Wrong prices online | Manual price updates |
How Much Does ERP Integration Cost?
Cost depends on the ERP, data flows, channels and custom business rules.
Scope | Typical timeline | Typical cost |
|---|---|---|
Connector setup and configuration | 2 to 4 weeks | $3,000 to $12,000 |
Custom store to ERP integration | 6 to 12 weeks | $15,000 to $50,000 |
Multi-channel, multi-warehouse integration | 3 to 6 months | $50,000 to $150,000 |
What changes the cost: ERP and its API, data flows, channels, warehouses, business rules and monitoring needs.
Ranges are typical for a global team. Your price is fixed after scoping, before any work starts.
Ways to Start Small
Starting point | Best for | From |
|---|---|---|
Fixing an unreliable sync | $29 | |
A ranked bug list for an existing platform | $199 | |
Ongoing fixes with a fixed budget | $290 for 10 hours |

Example Engagement: Stopping Overselling
An illustrative example based on the pattern we see most often. Client details are kept confidential.
The situation: A brand selling on its own store and two marketplaces oversold during sales because stock updated only twice a day.
What we did:
Connected store, marketplaces and ERP to one stock pool
Synced stock changes within minutes
Added alerts for failed syncs
The result: Overselling stopped, and orders reached the ERP automatically.
Mistakes to Avoid
Two systems both editing prices
Daily batch syncs for fast-moving stock
No alerts for failed syncs
Ignoring returns and cancellations
