Custom CRM, ERP and tools

Your SaaS subscriptions go up every year and your team works around the tool instead of with it. We build the CRM, ERP or internal tool that follows your processes instead. You own it: no per-user licence, your data stays yours.

What we often replaceExcel sheetsHubSpotSalesforcePipedriveSellsyAirtableNotionOnline ERPs

  • 01No per-user licenceYou pay for the build, then a fixed maintenance fee. Hiring no longer pushes the bill up.
  • 02You own the code and the dataSource code handed over, hosted in Europe or on your servers. No forced price rise at renewal.
  • 03Shaped around your processesYour steps, your rules, your roles. No useless fields, no spreadsheet on the side to fill the gaps.
  • 04AI agents built inReading emails and PDFs, follow-ups, meeting notes: repetitive tasks go to agents, people still decide.

Your SaaS against custom, over 5 years

Your SaaSCustomConnected business CRM or ERP · €25,000
Setup€3,000€25,000
Every year€16,200€5,550
Total over 5 years€84,000€52,750

The custom tool pays for itself after 25 months.

Indicative estimate: typical price of the chosen offer, maintenance at 15% a year, SaaS with €3,000 of setup, before price rises and paid add-ons. Under five users with a standard process, an off-the-shelf tool is often enough: we’ll tell you so. We redo the maths with your own numbers during the assessment.

Common questions

Do I really own the code?

Yes. The source code, documentation and access are handed over. You can keep improving it with us or with another team.

Can we move our data without losing anything?

Yes. We export the old tool (HubSpot, Salesforce, Pipedrive, Sellsy, Excel…), clean it up, then your team checks everything on a test environment before the switch.

Can all our software be connected?

Yes, all of it. Some tools are easier than others depending on what the vendor opens up (APIs, exports, email), but every one can be linked. The assessment tells you how, and what it costs.

What recurring costs should we expect?

Maintenance (15% of the price per year), hosting if we run it (from €150 excl. VAT a month), AI model usage by volume and any third-party services (e-signature, SMS). No per-user licence.
