Run every project, every hour, every euro — from one app.
MIBI is the mobile-first software that builders, project managers and admins actually use. Track time and expenses on site, manage planning and invoicing in the office, and speak to your team in their own language.
The old way is broken
Hours lost to paper time sheets
Crews fill in tickets that get lost, smudged, or arrive a week late — by which point nobody remembers what they did.
Expenses without receipts
Petrol, materials, parking — all paid for with personal cards, all forgotten by month end.
WhatsApp chaos
Twelve project chats, no search, no history when somebody leaves the team.
A workforce that speaks five languages
Polish, Romanian, Hungarian, Dutch, English — your software speaks one. Mistakes follow.
Built by an active construction company
Meestersinbouw, a 20+ year Dutch contractor working across residential, commercial and industrial projects, built MIBI to replace their patchwork of paper sheets, WhatsApp groups and spreadsheets. Today they run every project on it — and so can you.
— Meestersinbouw, Limburg, NL
Meestersinbouw runs every project on MIBI. Today, you can too.
One app. Built for site, run from the office.
Time tracking that takes 10 seconds
Workers tap project, tap hours, tap save. Locked dates and approval rules stop the chaos before it starts.
Expenses with photo receipts
Snap the receipt at the petrol pump. Categorise. Done. Admins approve and forward to your accountant.
Project chats that survive the year
WhatsApp-style group conversations per project, with full history, search, and a private channel for the client.
Five languages out of the box
English, Dutch, Polish, Romanian and Hungarian — every screen, every notification, every translated message.
Planning the whole crew can see
Drag-and-drop calendar with recurring events, public holidays per country, and a single view of who is where.
Invoices and quotes from the same data
Turn approved hours and expenses into draft invoices in one click. Send PDF quotations with module-level line items.
