Crux Digits builds the software a standard package leaves out: the link between your ERP and your CRM, the portal your customers use, the step Peppol did not remove. Fixed prices, delivered from the Utrecht region, and you own every line of code.
Last updated: 17 September 2026
Custom software pays when the process is what sets you apart and no package fits it without workarounds. For most Flemish organisations the value is in connecting what already runs, such as Odoo, Teamleader, Exact Online, WinBooks or Octopus, and in automating what Peppol did not: since 1 January 2026 Belgian B2B invoices arrive as structured data, but matching, exceptions and approval are still manual in most companies. Crux Digits works in three fixed steps: an audit at €2,500, a Production-ready MVP at €20,000 and production from €50,000, excl. VAT, with all source code handed over.
From workaround to software
Five steps from the manual workaround to software you own.
Data typed from one system into another, every day, by someone whose time is worth more.
Odoo, Teamleader, Exact Online or WinBooks connected through their APIs.
Structured Peppol invoices matched to orders and receipts; only exceptions reach a person.
Orders, status and documents in a web portal with the right roles and an audit trail.
Production handed over with documentation, access and all source code. No licence fee.
| What runs today | What custom software adds | What you measure |
|---|---|---|
| Odoo or Exact Online as ERP | Order intake from email and PDF, stock and pricing rules the standard modules do not cover | Minutes per order, order errors |
| Teamleader or another CRM | Quotes from standard components, follow-up and project handover to planning | Quote turnaround, quote-to-order rate |
| WinBooks, Octopus or Exact for accounting | Peppol invoices matched to orders and receipts, exceptions routed for approval | Share of invoices booked without touching |
| CODA bank statements | Payments reconciled against open items, differences flagged | Hours of reconciliation per month |
| Spreadsheets and email | A web application with the right roles, audit trail and AI where it saves real time | Time per task, errors, handovers |
If a package does 90% of the job and the rest is a habit rather than a competitive edge, buy the package and change the habit. Custom software is right when the workaround costs more each year than the build, when the process is how you win work, or when the data has to stay under your control. The audit answers that question on your own figures, and it is allowed to conclude that you should not build.
Audit, €2,500: the process mapped, systems and data checked, a scope with a fixed price. Production-ready MVP, €20,000: the core working in your systems, tested with your team. Production, from €50,000: integrated, secured, monitored and handed over with documentation and all source code. Prices excl. VAT; for Belgian businesses the VAT is normally reverse-charged. Discovery and go-live on site in Flanders, the build remotely. Where AI is part of the software, the EU AI Act risk checker shows the duties that come with it.
