For Nigerian shop owners & attendants

Replace the notebook. Run your shop from your phone.

Kobook tracks your inventory, sales, credit, and profit — fully offline, so you never need a data bundle just to get through the day. Simple enough for the boy at the counter, clear enough for the owner.

Coming soon to Google Play — in active development.

Works 100% offline

Log sales, adjust stock, record credit — all with zero data bundle. The shop never waits for a network.

Your data stays yours

Records live on your own phone. Backups go to your own Google Drive — we never hold a copy of your sales.

See your real profit

Not guesses. Gross and net profit, expenses, and losses — in ₦, in one report you can actually trust.

The paper notebook is costing you more than you think

Tracking stock and sales on paper leads to stockouts, undetected theft and shrinkage, and no real view of profit. Kobook gives you the same speed and simplicity your staff already know — with none of the blind spots.

Everything the shop needs, nothing it doesn't

Inventory & stock

Track products, categories, and stock levels in real time, with a full movement history behind every change.

Sales & credit

Log cash and credit sales at the counter, and keep a running ledger of exactly who owes what — and who gave it out.

Staff accounts

Give each staff their own PIN login, with owner-only controls kept separate. No shared passwords, no guesswork.

Profit & loss reports

Gross and net profit, expense breakdown, and damage loss — a clear picture of how the shop is really doing.

Expenses & cash count

Record daily expenses and reconcile the cash drawer — expected vs. actual — so shortfalls never hide.

Multiple shops, one account

Run more than one shop from a single account and switch between them in seconds, each with its own data.

Your shop's data belongs to you

Your products, sales, and every customer's credit balance stay on your device. If you turn on backup, a copy goes to your own Google Drive — under your Google account, controlled by you. We can't read it, and we never sell your data.
