The verdict in three sentences
Connecting Odoo to an e-commerce site and HubSpot costs between 5,000 and 16,000 EUR excluding VAT for a wholesale SME in Berlin in 2026, with a 4 to 8 week timeline. The integration removes double entry and saves around 20 hours a month, while eliminating stock and invoicing errors. An iPaaS such as Make, at 30 to 300 EUR a month, is enough for simple low-volume flows, but becomes fragile beyond a few thousand operations or once business rules get complex.
What to sync, and in which direction
The work starts with a flow map. Each piece of data needs a single master system, otherwise syncs overwrite each other. In a wholesale SME, Odoo masters stock, prices and invoices, HubSpot masters contacts and deals, the website masters carts and online orders.
| Flow | Master system | Direction | Frequency | Complexity |
|---|---|---|---|---|
| Available stock | Odoo | Odoo to website | every 5 min | medium |
| Prices and customer discounts | Odoo | Odoo to website | hourly | high |
| Online orders | website | website to Odoo | real time | medium |
| Contacts and companies | HubSpot | two-way | real time | high (duplicates) |
| Quotes and deals | HubSpot | HubSpot to Odoo | on signature | medium |
| Invoices and payment status | Odoo | Odoo to HubSpot and website | daily | low |
| Shipment tracking | carrier | to Odoo then customer | real time | low |
Custom or iPaaS: 2026 comparison
| Criterion | Custom connector | Make or Zapier | Off-the-shelf Odoo module |
|---|---|---|---|
| Setup | 5,000 to 16,000 EUR excl. VAT | 1,000 to 4,000 EUR of configuration | 300 to 1,500 EUR licence + 1,000 to 3,000 EUR of adaptation |
| Monthly cost | 80 to 200 EUR hosting and monitoring | 30 to 300 EUR by operations | 0 to 50 EUR |
| Comfortable volume | unlimited | up to 10,000 to 50,000 operations a month | varies |
| Business rules (discounts, B2B pricing) | all | limited, heavy scenarios | those built into the module |
| Error handling and retries | queue, alerts, replay | basic | varies |
| Odoo version upgrades | handled by the provider | often no impact | depends on module vendor |
| 3-year cost | 7,900 to 23,200 EUR | 2,100 to 14,800 EUR | 1,300 to 6,300 EUR |
Indicative 2026 ranges. An off-the-shelf module is the cheapest route when it covers 90 % of the need; custom is justified for negotiated B2B pricing, catalogues above 5,000 SKUs or multiple warehouses.
Classic pitfalls
Duplicate contacts often make up 10 to 20 % of a CRM; merge them before the first sync. Odoo version upgrades (one major release a year) break poorly built connectors: require automated tests and a staging environment. Finally, log every exchange so you can find out in minutes why an order did not arrive. Under GDPR, the sync must also respect consent fields between HubSpot and Odoo.
Mini case study
Lukas, manager of an industrial supplies wholesaler in Berlin (18 staff, 2,500 SKUs), has 150 web orders a week re-keyed into Odoo and then HubSpot. An assistant spends 20 hours a month on it, 700 EUR of loaded cost, and stock errors cause about 6 cancellations a month at 120 EUR of lost margin each. He picks a custom connector at 9,500 EUR excluding VAT and 120 EUR a month. Monthly saving: 700 + 720 = 1,420 EUR, minus 120 EUR, so 1,300 EUR net. The project pays back in just over 7 months, and customer discounts finally display correctly on the site.

FAQ
How much does an Odoo integration with a website and CRM cost in Berlin in 2026?
Budget 5,000 to 16,000 EUR excluding VAT depending on the number of flows, pricing rules and SKU volume. Recurring hosting and monitoring sit between 80 and 200 EUR a month.
Is Make enough to connect Odoo and HubSpot?
Yes for a few simple flows under 10,000 operations a month, for 30 to 100 EUR monthly. Beyond that, or with per-customer B2B pricing, scenarios become hard to maintain.
Do we need Odoo Enterprise or Community?
Both expose an external API, but Enterprise includes more modules and vendor support, around 25 to 40 EUR per user per month in 2026. The connector works with either.
What timeline should we plan?
From 4 weeks for 3 simple flows to 8 weeks for full sync with B2B pricing and multiple warehouses. Add 1 week of data cleaning if the CRM holds many duplicates.
What happens when Odoo is upgraded?
A well-built connector goes through staging and automated tests before each upgrade. Budget 1,000 to 2,500 EUR of adaptation per major version.
