The verdict in three sentences
In 2026, an iPaaS ERP-CRM integration in Berlin costs 6,000 to 25,000 EUR setup plus 50 to 500 EUR/month subscription, while a custom connector runs 15,000 to 50,000 EUR. In 2 to 6 weeks you remove double entry and gain 30 to 60% reliability on your customer and order data. The right question is not price: it is the synchronisation volume and the expected lifespan of the connection.
iPaaS integration costs in 2026
An integration is paid at setup then by subscription, indexed to operation volume. Here are 2026 orders of magnitude.
| Item | 2026 range (EUR) | Time |
|---|---|---|
| Scoping + field mapping | 1,000 - 3,000 | 3-5 days |
| Integration of 1-2 systems (iPaaS) | 6,000 - 12,000 | 2-3 weeks |
| Integration of 3-4 systems | 12,000 - 25,000 | 4-6 weeks |
| iPaaS subscription | 50 - 500 /month | ongoing |
| Monitoring + changes | 150 - 600 /month | ongoing |
Price rises with the number of synced objects (customers, products, orders, stock) and frequency (real time vs hourly).
iPaaS vs custom connector
iPaaS pools API maintenance; custom removes the subscription but concentrates cost and risk on you.
| Criterion | iPaaS | Custom connector |
|---|---|---|
| Setup | 6,000 - 25,000 EUR | 15,000 - 50,000 EUR |
| Monthly cost | 50 - 500 EUR | 0 - 200 EUR (infra) |
| Time to deliver | 2-6 weeks | 6-12 weeks |
| API maintenance | by the vendor | your responsibility |
| High volume (>200k ops/month) | costly | economical |
| Best for | standard connections | heavy business logic |
Below 100,000 operations/month, iPaaS almost always wins. Above that, or if the subscription exceeds 400 EUR/month, a custom connector pays back in 18-24 months.

Mini case study
Thomas, IT lead of a 70-staff services SME in Berlin, suffers double entry between his CRM and ERP: 2 sales reps spend 6 hours/week each re-keying orders, with 4% errors. Cost: 12 h x 45 weeks x 35 EUR = 18,900 EUR/year, before disputes. An iPaaS integration at 11,000 EUR + 180 EUR/month removes re-keying and errors. Return on investment in 9 months, then ~16,700 EUR/year saved net of subscription.
FAQ
How long to connect ERP and CRM? A first reliable sync is operational in 2 to 4 weeks for two standard systems. Complex cases (multi-warehouse stock) take up to 6 weeks.
Which iPaaS for an SME? Make and n8n offer the best cost/flexibility; Workato or Boomi target high volumes from several hundred euros/month. The choice depends on available connectors.
What do we gain concretely? End of double entry, 30 to 60% more data reliability, and shorter order-processing times. Sales reps refocus on selling.
iPaaS or custom long term? iPaaS is cheaper up to ~100,000 operations/month; beyond that, custom amortises its upfront cost in 18-24 months thanks to no subscription.
What if an API changes? With iPaaS, the vendor maintains the connector; with custom, a monitoring contract (150-600 EUR/month) covers adaptations.
