Custom business software: goodbye spreadsheets and manual steps
We build business software around your processes: inventory, orders, customers, staff, checks, reports. One system you can use from the office, phone and tablet, instead of shared spreadsheets, paper and phone calls.
When you need custom business software
- Data is scattered across spreadsheets, emails and notebooks
- The same data is copied by hand into several programs
- The software you use today doesn't do what you need
- Field staff still work on paper
- You need reports and checks that take hours today
What it can do
Roles and permissions
Everyone sees and edits only what they should, with a history of changes.
Reports and PDFs
Automatic reports, exports and documents ready to send.
Web and apps
An office dashboard and an app for people on the move, on the same data.
Integrations
Connections to ERPs like Odoo, accounting, e-commerce, existing databases and payments.
An example: Simple HACCP
For food service we built Simple HACCP: temperatures, expiry dates, allergens, checklists and inspection reports moved from paper to phones, with automatic reminders and reports ready in seconds.

How much does custom business software cost?
It depends on the number of features, users, integrations and platforms. After analysing your processes you get a detailed written quote.
Can we start from the data we have in spreadsheets?
Yes. Migrating existing data is part of the release: we import spreadsheets, databases and archives.
Does it work on phones?
Yes, it runs in the browser on computers, tablets and phones, and when needed we add a dedicated app.
Can it connect to the software we already use?
Yes, we integrate ERPs like Odoo, accounting software, e-commerce and existing databases, including older ones.
