WHERE YOU START

It starts with a quote. It ends with money in your account.

Build a quote in minutes, send it over WhatsApp, then turn it into an invoice the moment it's accepted. Progress bills (interim certificates), deposits, retention and escalating reminders — each one approved by you — are all built in: the whole of construction billing, without a spreadsheet.

Every day on site

What actually happens on site

Every everyday action — checking out a tool, receiving a delivery, paying an expense, clocking in — records itself. You do the work; the app remembers everything.

Tools & equipment

Scan the QR code on the way out and back. No more tools that vanish until the job is over.

Materials

Photograph and sign off a delivery while the driver waits. Every price you pay is captured.

Petty cash

Fuel, advances, small purchases: snap the receipt, pick a category, enter the amount. The cash envelope becomes a real ledger.

Labour

Clocking in in the morning starts the day. The day's pay is calculated automatically, and every Mobile Money payment is logged with its reference for each worker.

01

One action, one record

Pick up the tool, sign off the delivery, spend, clock in: the action itself creates the record. Nothing to re-enter at night.

02

It works without a signal

Everything is saved to the phone instantly, then synced as soon as the connection returns. Poor coverage never stops the work.

03

Your data works for you

Client reports, delay evidence, supplier prices, accounting exports: all generated from what you've already done.

Frequently asked questions

Does SangoChantier work without a signal?

Yes. Every action (tool check-out, materials receipt, cash expense, clock-in) is saved to the phone immediately, then synced automatically as soon as the connection returns. Poor coverage never stops the work on site.

How do I pay workers and keep a record of it?

After clock-in, SangoChantier calculates each worker's pay for the day. You pay the way you already do — Mobile Money (M-Pesa, MTN MoMo, Wave, Orange Money…), bank transfer or cash — and the app logs every payment with its reference: a reliable record for you and for the worker.

Does it handle progress bills (interim certificates) and retention?

Yes. You create a quote, send it over WhatsApp, then turn it into an invoice. Progress bills, deposits, retention and escalating reminders — each approved by you — are built in: the whole of construction billing, without a spreadsheet.
