The verdict in three sentences
Connecting your B2B store to the ERP for real-time stock, pricing and orders costs between 18,000 and 55,000 CAD in Toronto in 2026, depending on available APIs and the number of flows. The immediate gain is the end of falsely displayed stockouts and 15 to 25 hours per week of manual syncing. Success rests on three things: caching strategy, discrepancy handling and reliable order webhooks.
What the integration covers and its cost
Integration is not a simple connector: it is a synchronization contract between two systems that do not speak the same language.
| Flow | 2026 range (CAD) | Typical frequency |
|---|---|---|
| Real-time stock | 5,500 - 15,000 | real time / 1-5 min |
| Pricing and per-customer grids | 4,500 - 13,000 | hourly / on demand |
| Product data (PIM) | 3,500 - 11,000 | daily |
| Orders to ERP (webhooks) | 4,500 - 12,000 | real time |
| Statuses and deliveries | 3,500 - 9,000 | real time |
| Reconciliation / discrepancy handling | 3,500 - 10,000 | continuous |
A standard project sits around 26,000 to 40,000 CAD; with several warehouses and complex pricing, it reaches 55,000 CAD.
The hidden cost of manual syncing
Without integration, someone exports, corrects and re-imports files. It is slow, expensive and a source of commercial errors.
| Metric | Manual sync | Integrated ERP |
|---|---|---|
| Weekly sync time | 15 - 25 h | < 1 h |
| Falsely displayed stockouts | frequent | near zero |
| Stock update delay | 12 - 48 h | 1 - 5 min |
| Customer price errors | 2 - 5 % | < 0.3 % |
| Orders re-keyed into ERP | 100 % | 0 % |
| Monthly cost (partial FTE) | 3,000 - 5,000 CAD | marginal |
Over a year, removing 20 hrs/week of syncing means over 1,000 hours handed back to teams, roughly 35,000 to 55,000 CAD of avoided cost.
Mini case study
David, e-commerce lead of an electrical-equipment distributor in Toronto (12,000 SKUs, 2 warehouses), integrates his B2B store with the ERP for 35,000 CAD. Before, an employee spent 22 hrs/week syncing stock and prices, and falsely displayed stockouts cost about 3 % of revenue in lost orders. Integration cuts syncing below 1 hr/week and divides phantom stockouts by 10. On 2M CAD/year revenue, recovering 2 points of lost orders means 40,000 CAD/year: project pays back in under a year.

FAQ
Why is real-time stock so important in B2B?
A professional buyer who orders a product shown available but out of stock loses trust and goes to a competitor. Real time (1-5 min update) makes every order reliable and cuts disputes.
How do you manage load on the ERP?
With a caching strategy: stock is cached on the store side and refreshed via webhooks or short polling, without querying the ERP on every page. This shields the ERP from traffic spikes.
What happens on a stock discrepancy?
A reconciliation rule decides: the ERP is authoritative, the store aligns, and discrepancies are logged for audit. In-flight orders are secured by a stock reservation.
Webhooks or polling?
Ideally webhooks (the ERP pushes changes), with fallback polling if the ERP does not expose them. Most modern ERPs support at least one of the two.
How long to integrate?
Allow 6 to 12 weeks depending on the ERP's APIs. The critical point is documentation quality and the stability of pricing flows.
