The verdict in three sentences
An ERP to e-commerce integration costs between USD 16,000 and USD 55,000 in 2026, depending on the number of flows and the level of real-time sync. The concrete gain: order errors -30 to -60 percent and the end of double data entry between ERP and site. The trade-off: does a market-native connector suffice, or do your rules require a custom connector?
The flows to sync and their cost
A serious integration covers at minimum stock, prices and orders. Here is the Toronto 2026 breakdown per flow.
| Flow | 2026 range (USD) | Target frequency |
|---|---|---|
| Stock (ERP -> store) | 3,300 - 10,000 | Real-time / 15 min |
| Prices + per-customer pricing | 4,400 - 13,000 | Real-time |
| Orders (store -> ERP) | 4,400 - 13,000 | Real-time |
| Product data / PIM | 3,300 - 11,000 | Daily |
| Customers + credit limits | 2,700 - 8,800 | Real-time |
| Monitoring + error recovery | 2,200 - 6,600 | Continuous |
A targeted integration (stock + orders) starts at USD 16,000. A full real-time sync (per-customer pricing, credit limits, PIM) reaches USD 50,000 to 55,000.
Native connector or custom build?
The choice depends on your ERP and the granularity of your rules. Here is the 2026 trade-off.
| Criterion | Native connector | Custom connector |
|---|---|---|
| Upfront cost | 3,300 - 16,000 USD | 16,000 - 55,000 USD |
| Monthly subscription | 110 - 550 USD | Hosting 55 - 220 USD |
| Per-customer pricing | Often limited | Unlimited |
| Real-time | Variable | Guaranteed |
| Niche ERPs | Rare | Supported |
| Connector maintenance | Partly included | 330 - 1,000 USD/month |
If your ERP is common (NetSuite, Sage, Odoo) and your rules standard, a native connector suffices. Once per-customer pricing or a niche ERP is involved, custom becomes necessary.

Mini case study
Thomas, operations director of a technical-parts distributor in Toronto, handles 140 orders/day re-keyed manually from the store into the ERP. A 4.5 percent error rate generates credit notes and returns estimated at USD 41,000/year. A real-time integration at USD 37,000, maintenance USD 650/month, cuts the error rate to 1.2 percent: estimated saving of USD 30,000/year, plus 2 h/day of entry removed. Estimated payback in about 15 months, maintenance included.
FAQ
How much is an ERP to B2B store integration? Between USD 16,000 and USD 55,000 depending on the number of flows and required real-time sync. Per-customer pricing and orders are the most complex flows.
How much do order errors drop? A well-designed sync cuts errors by 30 to 60 percent by removing double entry between ERP and store.
What is the integration timeline? Between 6 and 14 weeks depending on the ERP, the existence of an API and the number of flows. An ERP without its own API stretches the timeline.
What is the connector maintenance cost? Plan for maintenance of USD 330 to 1,000/month for monitoring, error recovery and format evolutions.
Do we need real-time everywhere? No: stock and orders benefit from real-time, but product data can sync once a day, which reduces cost.
