The verdict in three sentences
The right choice is not ideological; it depends on operation volume, transformation complexity and your security requirements. In 2026 an iPaaS costs from EUR 20/month (Zapier SMB) to EUR 12,000-40,000/year (Workato/Boomi enterprise), while a custom connector means EUR 8,000-25,000 one-off plus maintenance. The winning answer is often hybrid: iPaaS for the periphery, custom API for the critical core.
The cost of both approaches
iPaaS bills per task or per operation volume: an occasional flow costs almost nothing, but a high-volume flow can explode. Custom has a higher upfront cost but no per-operation bill.
| Solution | Entry cost | Cost at scale | Model |
|---|---|---|---|
| Zapier / Make (SMB) | 20 - 100 EUR/mo | 300 - 800 EUR/mo | Per task |
| Workato / Boomi (enterprise) | 12,000 EUR/yr | 40,000 EUR/yr+ | Per connector + volume |
| Custom connector | 8,000 - 25,000 EUR | Maint. 150-500 EUR/mo | One-off + maintenance |
| Hybrid model | 5,000 - 15,000 EUR | iPaaS + maint. | Mixed |
Break-even by volume
The tipping point is calculated on monthly operation volume. Below a few thousand operations, iPaaS wins; beyond that, per-task cost makes custom more profitable over 3 years.
| Monthly volume | iPaaS (cost/yr) | Custom (amortized cost/yr) | Recommendation |
|---|---|---|---|
| < 2,000 ops | 600 - 1,500 EUR | 6,000 - 9,000 EUR | iPaaS |
| 2,000 - 20,000 ops | 3,000 - 8,000 EUR | 7,000 - 11,000 EUR | iPaaS or hybrid |
| 20,000 - 100,000 ops | 12,000 - 30,000 EUR | 9,000 - 14,000 EUR | Custom |
| > 100,000 ops | 40,000 EUR+ | 12,000 - 20,000 EUR | Custom |
Beyond price, four criteria decide: latency, governance, lock-in and internal skills.
| Criterion | iPaaS | Custom |
|---|---|---|
| Time to deploy | Days | Weeks |
| Complex transformations | Limited | Unlimited |
| Security / on-premise | Variable | Full control |
| Vendor lock-in | High | Low |
| Skills required | Low | Backend dev |

Mini case study
Karim, IT architect at a 60-person logistics scale-up in Dubai, runs 12 integrations. Eight are light flows (notifications, contact sync) and four are critical (real-time parcel tracking, 80,000 operations/month). He keeps the eight light ones on Make (EUR 280/month, i.e. EUR 3,360/year) and has the four critical ones custom-built (EUR 19,000 + EUR 400/month maintenance). In pure enterprise iPaaS the critical flows would have cost over EUR 30,000/year. The hybrid saves him roughly EUR 11,000 per year from year one.
FAQ
At what volume does iPaaS get too expensive? Generally beyond 20,000 to 50,000 operations per month per flow, per-task cost exceeds the 3-year amortization of a custom connector.
Is iPaaS lock-in a real risk? Yes: your flows are described in a proprietary tool. Migrating 20 Zapier scenarios to Workato or to custom can cost EUR 5,000-15,000 of re-development.
Can I start on iPaaS then move to custom? Yes, it is even common. You prototype fast on iPaaS to validate the need, then internalize as custom the flows that become critical or costly.
Which iPaaS for an SMB? Zapier or Make for simple needs (EUR 20-400/month); Workato or Boomi for governance and high volumes (EUR 12,000-40,000/year). The choice depends on volume and security requirements.
Does the hybrid model complicate maintenance? A little, but it optimizes budget: you pay iPaaS only for low-volume periphery and control the critical core in-house. It is the best cost/control ratio for most scale-ups.
