The verdict in three sentences
In 2026, a custom API integration between your ERP and a web application costs between 25,000 and 90,000 MAD per connector, i.e. 200,000 to 600,000 MAD for a full multi-system project. Price depends on the target system (a Sage connector is pricier than a well-documented HubSpot one), the exchange mode (REST, webhooks or iPaaS) and data volume. Always budget API maintenance of 1,500 to 5,000 MAD/month: vendor APIs evolve and break unmaintained integrations.
REST vs webhooks vs iPaaS
Three approaches, three cost and reliability profiles. The choice happens during scoping based on your real-time needs and volume.
| Approach | Upfront cost (MAD) | Recurring cost | Good for |
|---|---|---|---|
| REST API (polling) | 25,000 - 60,000 | 1,500 - 3,000/mo | Periodic syncs |
| Webhooks (real time) | 35,000 - 80,000 | 2,000 - 4,000/mo | Instant events |
| iPaaS (Make/Zapier pro) | 15,000 - 40,000 | 3,000 - 12,000/mo | Prototype, low volume |
| Custom middleware | 60,000 - 150,000 | 3,000 - 5,000/mo | High volume, critical |
iPaaS is fast and cheap to start, but its subscription rises quickly with volume. For a critical, high-volume integration, custom middleware is cheaper over 2-3 years.
Cost per target system
Not all integrations are equal: the quality of the vendor's API swings the price up to threefold.
| System | API complexity | Connector cost (MAD) | Timeline |
|---|---|---|---|
| HubSpot (CRM) | Low, well documented | 25,000 - 45,000 | 4-6 weeks |
| Odoo (ERP) | Medium | 35,000 - 70,000 | 5-8 weeks |
| Sage (accounting) | High, legacy | 50,000 - 90,000 | 6-10 weeks |
| Salesforce | Medium, rich | 40,000 - 80,000 | 5-9 weeks |
| In-house / legacy tool | Very high | 60,000 - 120,000 | 8-12 weeks |
A typical project (CRM + ERP + accounting) combines 3 connectors and thus sits around 200,000 to 400,000 MAD, plus maintenance.
Mini case study
Karim, IT director of a distribution company in Dublin operating in Rabat (85 staff), managed invoicing in a recent web app but manually re-keyed every invoice into Sage and every client into HubSpot. That tied up 1.5 FTE at about 9,000 MAD/month each, i.e. 13,500 MAD/month of re-keying, with a non-trivial error rate.
He invested 165,000 MAD in two connectors (web app to Sage via webhooks, web app to HubSpot via REST) plus 3,500 MAD/month of maintenance. Result at 5 months: re-keying nearly eliminated, ~1.2 FTE freed (10,800 MAD/month recovered), invoicing errors sharply down. Estimated payback around 17-19 months, one of the fastest returns in the project portfolio.

FAQ
How long for an API integration?
Expect 4 to 10 weeks per integration in 2026, depending on target API complexity and volume. A well-documented HubSpot connector takes 4-6 weeks; a legacy Sage connector can reach 10 weeks.
iPaaS or custom development?
iPaaS (Make, Zapier) is ideal for prototyping or low volumes (3,000 to 12,000 MAD/month). Once volume grows or the integration becomes critical, custom becomes cheaper and more robust over 2-3 years.
Why monthly API maintenance?
Vendors (Sage, HubSpot, Odoo) evolve their APIs: new versions, deprecations, auth changes. Maintenance of 1,500 to 5,000 MAD/month ensures your integrations don't break silently.
What happens if the API goes down?
A well-designed integration includes queues, automatic retries and alerts. It's a point to require in the specification, especially for invoicing and payment flows.
Can we integrate an in-house tool with no API?
Yes, but it's costlier (60,000 to 120,000 MAD): you may need to go through the database, file exports/imports or build an API layer. Evaluate this before any commitment.
