Know what you sold, who has paid, who still owes you, and where your money is going — all in one simple place.
Why OpenBooks
Four ideas. One simple system. Scroll slowly — the cards are designed to stay with you before the next one takes its place.
Sales, customers, invoices, payments and expenses without turning your business into an accounting class.
Bank transfer, cash, POS or online payment with Paystack. Your business decides what appears on every invoice.
OpenBooks keeps outstanding balances beside the customer and invoice that created them, so you stop guessing.
The core is open source, built around ordinary Nigerian business workflows and designed to stay useful on a phone.

Step 1 of 4
For the barber closing the shop, the freelancer sending one last invoice, the tailor waiting on a transfer, the phone repairer trying to remember who still owes them. OpenBooks is built around those moments.
OpenBooks NG
Start with one customer, one sale and one invoice. That's enough to see what OpenBooks is about.
