The verdict in three sentences
An API connector between Sage and your website costs between EUR 6,000 and 18,000 excl. VAT in 2026, depending on how many data flows are synchronised. For an SMB re-keying 40 orders a day, it removes 2 hours of daily data entry and most item code or pricing errors. Plan 6 to 10 weeks of project time and EUR 150 to 400 per month in maintenance, with payback often under 12 months.
Which flows to sync between Sage and the website
Manual re-keying is the classic symptom of an e-commerce site or B2B portal disconnected from the ERP. Every web order is typed again into Sage, online stock levels are a day old and invoices are emailed by hand. A serious integration handles four main flows, each with its own direction and frequency.
| Flow | Direction | Recommended frequency | Indicative 2026 cost (EUR excl. VAT) |
|---|---|---|---|
| Customers and B2B accounts | Site to Sage, then Sage to site | Real time or every 15 min | 1,500 to 3,500 |
| Items and prices | Sage to site | Hourly | 1,500 to 4,000 |
| Stock per warehouse | Sage to site | Every 5 to 15 min | 1,000 to 3,000 |
| Orders | Site to Sage | Real time | 1,500 to 4,000 |
| Invoices and credit notes PDF | Sage to customer area | Daily | 800 to 2,000 |
| Delivery statuses | Sage or carrier to site | Hourly | 700 to 1,500 |
| Error log and alerts | Internal | Continuous | Included or 500 to 1,000 |
A connector limited to orders and stock starts around EUR 6,000. The full integration, with negotiated customer pricing, invoice area and alerts, reaches EUR 15,000 to 18,000.
Off-the-shelf connector or custom build
Several ready-made connectors exist for Sage and common CMS platforms. They fit if your rules are standard. As soon as you have discounts per product family, multiple warehouses or payment terms per customer, a custom build through the Sage API or an intermediate database becomes more reliable.
| Criterion | Standard connector | Custom integration |
|---|---|---|
| Initial cost | EUR 1,500 to 5,000 | EUR 6,000 to 18,000 |
| Subscription or maintenance | EUR 50 to 200 per month | EUR 150 to 400 per month |
| Customer-specific pricing | Partial | Complete |
| Multi-warehouse | Often paid extra | Included |
| Error handling | Basic | Log, retry, email alert |
| Timeline | 2 to 4 weeks | 6 to 10 weeks |
| Vendor lock-in | High | Code and documentation delivered |
What makes a budget drift
Three issues explain most overruns. Data quality first: duplicate item codes or incomplete customer records need 1 to 3 days of cleaning before any sync. Sage version next: an old unsupported version may require an upgrade, to be budgeted with your reseller. Hosting last: Sage installed on a local server needs secure access (VPN or agent) to talk to a cloud-hosted site. A 2 to 3 day scoping phase, billed EUR 1,200 to 2,000, locks these points before the final quote.
Mini case study
Aoife, CFO of an industrial supplies SMB in Dublin, sees her assistant re-key 40 web orders a day into Sage at 3 minutes per order, 2 hours daily. Over 220 working days, that is 440 hours a year, around EUR 13,200 at a loaded EUR 30 per hour. Add about ten pricing errors a month, each costing 30 minutes to fix. The custom connector is quoted at EUR 11,500, plus EUR 250 monthly maintenance, EUR 14,500 in year one. The direct gain of EUR 13,200 a year, plus avoided errors, gives a payback of about 11 months, and the assistant now focuses on customer collections.
