iPaaS for SMEs: Connect Your Tools and Automate Your Workflows
Your company uses 10 to 50 different tools. Without integration, your teams spend hours copying and pasting data between systems. An iPaaS solves this problem by connecting all your tools automatically.

What is an iPaaS? (Simple Explanation)
An iPaaS (Integration Platform as a Service) is a cloud platform that connects your applications together. In practice, it's the tool that makes your CRM 'talk' to your invoicing, your website to your ERP, or your email inbox to your project management tool.
Without an iPaaS, your tools work in silos: your sales reps enter the same information in HubSpot AND Pennylane, your accountant re-types invoices received by email, and your manager spends 2 hours a week consolidating data from 5 different tools.
With an iPaaS, these data transfers are automatic. A new client in the CRM? The record is instantly created in accounting, the project is created in your management tool, and a welcome email is sent. Zero human intervention, zero errors.
How does an iPaaS work?
1. Trigger
An event occurs in a tool (new contact, new order, email received...)
2. Processing
The iPaaS retrieves the data, transforms it if needed (format, calculations, AI enrichment)
3. Action
The data is automatically sent to one or more destination tools

Frequently Asked Questions About iPaaS for SMEs
An iPaaS is a platform that connects your tools together automatically. Instead of copying and pasting data between your CRM and your accounting software, the iPaaS does it for you in real time. It's like a universal translator between all your applications.
The tool itself costs between 0 EUR (self-hosted n8n) and 50-200 EUR/month (Make, Zapier) depending on your volume. Implementation by our team costs between 3 and 15 days depending on complexity. ROI is typically achieved in 2-3 months thanks to the hours saved.
No. Modern iPaaS tools (Make, Zapier) are designed to be used without technical skills. n8n is slightly more technical but offers more power. In all cases, we train your teams to be autonomous on day-to-day workflows.
It depends on the tool chosen. Self-hosted n8n keeps your data on your own servers in France -- ideal for sensitive data. Make hosts in the EU. Zapier hosts in the USA. We recommend self-hosted n8n for SMEs with regulated data (healthcare, finance, HR).
A simple flow (CRM -> invoicing) deploys in 1-2 days. A complete project (5-10 integrations) takes 2-4 weeks. We always start with quick wins to prove value quickly.
An API is the 'power outlet' of a tool -- it enables connection. The iPaaS is the 'smart extension cord' that uses APIs to create automated flows between multiple tools, without you having to write code. The iPaaS also handles errors, logs and monitoring.
