The verdict in three sentences
A multi-tool sync project (central hub + connectors) costs 10,000 to 25,000 EUR in 2026, over 6 to 12 weeks. The core trade-off is iPaaS (Make, n8n, 20-200 EUR/month) versus custom development. The payoff: a single source of truth and -70% data-entry errors.
The scattered-data problem
An SME accumulates tools: CRM for leads, billing for sales, e-commerce for orders, spreadsheets for the rest. Without sync, the same information is entered 3 or 4 times, each copy drifting further apart. The hidden cost: decisions made on wrong numbers.
| Symptom | Cause | Hidden cost |
|---|---|---|
| Diverging customer records | Multiple entry | Missed follow-ups, duplicates |
| Contradictory revenue figures | Multiple sources | Wrong decisions |
| Wrong e-commerce stock | No sync | Stockouts, overselling |
| Time lost on export/import | Manual process | 5-15 h/week |
iPaaS or custom development?
iPaaS (Make, n8n, Zapier) connects standard tools fast via visual scenarios. Custom development builds a bespoke hub, more robust on high volumes and complex logic.
| Criterion | iPaaS (Make, n8n) | Custom development |
|---|---|---|
| Upfront cost | 2,000 - 8,000 EUR | 10,000 - 25,000 EUR |
| Recurring cost | 20 - 200 EUR/mo | 200 - 500 EUR/mo |
| Timeline | 2-5 weeks | 6-12 weeks |
| Volume supported | Medium (operation quotas) | High |
| Complex business logic | Limited | Unlimited |
| Platform lock-in | Strong | Low |
| Best for | Standard flows, SMEs | High volumes, fine rules |
Good reflex: start on iPaaS to validate the flows, then move to a dedicated hub if volumes or rules exceed the platform's limits.

Élodie, COO of a distribution SME in Toulouse (40 staff), syncs CRM, billing, e-commerce shop and a stock spreadsheet. Custom quote: central hub 9,000 EUR, 4 connectors 12,000 EUR, migration 3,000 EUR, i.e. 24,000 EUR over 10 weeks. Recurring: 350 EUR/month.
Previously, 2 people spent ~10 h/week reconciling files, with a high error rate. After: -70% errors and 8 h/week recovered × 46 weeks × 33 EUR = 12,144 EUR/year, plus reliable decisions. Payback in ~24 months, before qualitative gains.
FAQ
What budget to sync 4 tools? Budget 10,000 to 25,000 EUR in custom development (hub + connectors + migration), or 2,000 to 8,000 EUR in iPaaS with a 20-200 EUR/month subscription. The choice depends on volume and complexity.
What is a single source of truth? It's the tool designated as reference for each data type: CRM for customers, billing for revenue, etc. The hub propagates that reference everywhere, eliminating contradictory versions.
iPaaS or custom for an SME? For standard flows and moderate volumes, iPaaS is enough and starts in 2-5 weeks. Beyond a few thousand operations/day or with fine business rules, the dedicated hub becomes cheaper.
How many errors can we avoid? On average -70% data-entry errors once double entry is removed. For an SME, that means fewer customer duplicates, reliable stock and consistent numbers.
What's the implementation timeline? From 2-5 weeks on iPaaS to 6-12 weeks in custom development, data migration included. A one-week scoping phase avoids costly back-and-forth.
