The verdict in three sentences
A custom integration connector between your CRM and ERP costs EUR 10,000 to 28,000 net for 4 to 8 weeks, versus a licensed iPaaS at EUR 500 to 1,500/month that bills forever. It removes an average of 12 hours of re-keying per week and makes your data reliable (one source of truth per flow). For a Dubai IT lead with stable volumes and specific business rules, custom beats iPaaS within 18 to 30 months.
Custom or iPaaS: the real trade-off
iPaaS platforms (advanced Zapier, Make, or enterprise tools) deploy fast but cost every month and cap out on complex business rules. A custom connector demands a higher upfront investment but becomes your asset.
| Criterion | Custom connector | Licensed iPaaS |
|---|---|---|
| Upfront cost | EUR 10,000 – 28,000 net | EUR 0 – 3,000 (setup) |
| Recurring cost | Maintenance EUR 350 – 800/mo | EUR 500 – 1,500/mo |
| Complex business rules | Unlimited | Often limited |
| Flow volume | No per-operation surcharge | Often volume-billed |
| Code ownership | Yours | Vendor lock-in |
| Deployment time | 4 to 8 weeks | 1 to 3 weeks |
Simple rule: above ~EUR 800/month of iPaaS, or with strong business rules, custom wins over 3 years.
Budget and line items 2026
Vendor day rate of EUR 480 to 680 net in the Dubai region. Scope depends mostly on the number of flows (contacts, quotes, orders, invoices, stock) and sync direction (one-way or two-way).
| Line item | 2026 range (EUR net) | Note |
|---|---|---|
| Flow audit + mapping | 2,000 – 4,000 | Fields, rules, duplicates |
| Connector development | 6,000 – 18,000 | API / webhooks, queues |
| Error handling + replay | 1,500 – 4,000 | Robustness, alerting |
| Testing + cutover | 1,000 – 3,000 | Tests on real data |
| Monthly maintenance | 350 – 800 / month | API monitoring, changes |
Budget EUR 10,000 net for 2 to 3 one-way flows, EUR 20,000 to 28,000 net for a rich two-way sync with fine-grained error handling.

Mini case study
Sarah is the IT lead of a 40-person trading SME in Dubai. Three sales-admin staff re-key orders from HubSpot into Sage: ~12 hours/week combined at a loaded cost of EUR 32/h, i.e. EUR 384/week or ~EUR 18,400/year, plus credit notes from entry errors (estimated EUR 6,000/year). A two-way connector at EUR 22,000 net plus EUR 600/month maintenance removes the re-keying and 80 % of errors, i.e. ~EUR 23,200 saved in year one. Against an iPaaS at EUR 1,200/month (EUR 14,400/year), custom becomes cheaper from month 20 while staying your property.
FAQ
Does a connector break at every API update? Not if well designed: call versioning, automated tests and alerting. Maintenance (EUR 350 to 800/month) covers exactly the adaptations to HubSpot, Sage or Odoo changes.
Real-time or batch sync? Both are possible. Real-time (webhooks) suits quotes and orders; nightly batches often suffice for stock or accounting and cost less to run.
What happens on a data conflict? We define a source of truth per field and priority rules. Conflicts are logged and replayable, never silently overwritten.
Can we start small? Yes. We often begin with the most painful flow (orders or invoices), measure the gain, then extend. That spreads the budget and secures the ROI.
How long to production? 4 to 8 weeks depending on the number of flows and rule complexity. A gradual, flow-by-flow cutover limits risk.
