From zero to selling

Four steps. One running shop.

1

Apply

Two minutes: your shop name, your TIN, your phone. No card needed.

2

We set you up

Within a day your shop is live, books seeded, tax set up to match RRA.

3

Start selling

Connect a printer, scan a barcode, tap MoMo. A short walk-through and you're off.

4

Close the day

The end-of-day report runs itself. Profit and loss the moment you lock the door.

At the counter

A sale takes one tap.

Search or scan, pick the customer, tap how they paid. DUKA writes the invoice, posts the books, drops the stock, and adds the tax, all before the receipt finishes printing.

  • Cash, MoMo, Airtel, or on credit
  • Receipt to print or send on WhatsApp
  • Works on a phone, tablet, or counter screen

Books that keep themselves.

  • Who owes you and who you owe, always current
  • VAT worked out and ready for RRA
  • Your accountant sees it from their own screen

The position

It runs your shop.

“Live books used to be a fancy feature for big companies. They should be normal for every shop in Kigali.”

Questions

The things you'd ask.

Yes. The Free plan covers selling, invoicing, purchases, and RRA EBM receipts, with no cap on items or customers. No card to sign up. You only pay when you want the next layer, like inventory or full books.

Never. Every plan keeps unlimited items, customers, and suppliers. Higher plans unlock new abilities like inventory, bookkeeping, and financial statements, not bigger numbers.

Yes, from the Free plan. Every sale can produce a EBM receipt with your TIN and the QR slot, and VAT is worked out for you at 18%. Direct certification is rolling out shop by shop.

Yes. Your accountant gets their own login and can see your books, along with all their other DUKA clients, from one dashboard. Cheaper and faster than a monthly bookkeeper.

The counter keeps selling offline and syncs the moment you're back online. Your data is backed up daily and hosted under local data-protection rules.

Under a day. You apply in two minutes, we provision your shop, seed the books, and set tax to match RRA. Then a short walk-through and your first sale.

Open your shop in two minutes.

Free to start. Tax-legal from the first sale. No card, no contract.
