The verdict in three sentences
Connecting your ERP to your website eliminates the double entry between back office and online store, a source of stock and price errors. In 2026, a connector costs USD 10,000 to 30,000 depending on the number of flows and the mode (real-time or batch), with maintenance of USD 170 to 550/month. Setup takes 4 to 8 weeks.
Cost by flow type
| Synced flow | Direction | Complexity | 2026 cost (USD) |
|---|---|---|---|
| Product catalog | ERP → site | Medium | 3,500 – 7,000 |
| Stock levels | ERP → site | Low | 2,400 – 4,800 |
| Prices and customer tariffs | ERP → site | Medium | 3,000 – 6,000 |
| Orders | site → ERP | High | 4,800 – 9,500 |
| Customer records / accounts | bidirectional | High | 3,500 – 7,000 |
| Invoices / credit notes | ERP → site | Medium | 3,000 – 6,000 |
Few projects sync every flow: most start with catalog + stock + orders, the trio that removes the most errors.
Real-time or batch, and by scenario
| Scenario | Mode | 2026 budget (USD) | Maintenance |
|---|---|---|---|
| Simple catalog showcase | Daily batch | 10,000 – 14,000 | 170 – 290 /mo |
| Active B2C e-commerce | Real-time stock | 14,000 – 21,000 | 290 – 450 /mo |
| B2B e-commerce (customer tariffs) | Real-time + pricing | 21,000 – 30,000 | 400 – 550 /mo |
| Multi-warehouse / multi-site | Advanced real-time | 30,000 + | 550 + /mo |
Real-time stock is essential as soon as you sell fast-moving products: it prevents selling out-of-stock items and issuing refunds.
Mini case study
Karim, IT director of a 60-person B2B distributor, manages 4,200 SKUs in Sage. Without a connector, his team re-keys stock and orders: about 90 hours/month at a loaded cost of USD 24/hour, i.e. USD 2,160/month. On top of that, error costs (out-of-stock sales, credit notes) are estimated at USD 1,300/month. A real-time catalog + stock + orders connector quoted at USD 17,000, plus USD 380/month maintenance, removes most of these costs. Payback lands around 8 to 10 months, with a site finally reliable on availability.

Standard or custom connector?
If your ERP and CMS have a reliable off-the-shelf connector, use it. As soon as your customer tariffs, discount rules, or multi-warehouse logic go beyond standard, custom avoids costly workarounds.
Real-time or batch: how to decide?
A daily batch is enough for a stable catalog. Real-time is a must for fast-moving stock and personalized B2B pricing, where an error costs money immediately.
What if the ERP is unavailable?
A good connector uses a queue and replays syncs after an incident, with no lost orders. This recovery mechanism is one of the points to validate in the spec.
How much is maintenance?
Expect USD 170 to 550/month depending on criticality and number of flows. It covers monitoring, ERP-side API changes, and adding new fields.
How long to go live?
Between 4 and 8 weeks for common scenarios. Multi-warehouse or complex customer-tariff cases can reach 10 to 12 weeks.
