Point of sale · Inventory · Built for Ghana

The till that never stops selling. Even when the network does.

Opti Shop runs your counter, your stock and your customer credit across every branch. Every sale is saved on the device first, so light-off, data-off and bad-signal days never cost you a customer.

Selling, stock, purchasing, credit, cash-up and reports in one install for each client. Owners see every branch. Cashiers see only their till.

POS

A counter built for queues

Barcode scan, search or category tiles. Hold and resume carts, weighed items, line and sale discounts, and big touch targets for tablets.

Inventory

Stock as a ledger

Every sale, delivery and adjustment is an append-only movement. Stock counts show variances before anything posts.

Cash, MoMo, card, split

Manual mobile money that works offline, or a payment link with a QR that confirms itself through Paystack.

02 / Offline-first

Cut the internet. Watch nothing break.

Each till keeps its own copy of products, prices and staff. Sales queue on the device with their own IDs and post to the server once the line comes back, with no duplicates and nothing lost. Try it below.

Network online Africa/Accra · —

Drag to rotate

3D preview needs WebGL. Every sale still queues on the device and syncs when the line returns.

Client UUIDs

Sales, payments and stock moves get their IDs on the device, so two offline tills never clash.

Snapshots

Each sale line keeps its name, price, cost and tax as they were. Later edits never rewrite history.

Negative stock

A sale that already happened is never blocked. It is flagged for review after the sync.

Two clocks

Device time and server time are both stored in UTC and shown in Africa/Accra.

03 / Try the till

Ring up a sale. Right here.

Tap products to build a cart, then pay with cash, a mobile money link or a balance. The maths uses whole pesewas, never floats, the same way the real till does.

04 / Mobile money, done properly

The browser never gets to say "paid".

A payment link is confirmed only by a verified gateway callback or a server-side check. Callbacks are stored first and processed once. A late payment on an expired link is still recorded and flagged for the manager.

01 · Till

Link for the exact amount

The sale waits for payment. No stock is posted yet, and the link expires in 15 minutes.

02 · Customer

Scans the QR and pays

The customer pays on their own phone. The amount is locked to the link.

03 · Gateway

Calls your server

The signature is checked, then a verify request goes to Paystack.

04 · Server

Confirms once

The callback is idempotent, so a repeated call never creates a second payment.

05 · Till

Sale completes itself

Stock posts, the receipt prints and the cashier moves to the next customer.

CashOffline

Change in one tap

Cash received, change due, and the amount feeds the shift's expected cash.

MoMo manualOffline

Reference entry

Taken offline as pending. A manager later confirms it against the statement.

MoMo linkOnline

QR + WhatsApp share

Your own Paystack keys, so the money goes straight to your account.

BalanceOffline

Part pay, rest owed

Checked against the credit limit. Going over the limit needs a manager's PIN.

05 / Inventory

Stock you can audit, line by line.

Movements are never edited or deleted. A mistake is corrected with a new movement, and the stock level updates in the same database transaction.

08 / Questions

Asked at every counter.

01Does it really work with no internet?

Yes. Once a till has opened online one time, it keeps products, prices and staff on the device. Sales, cash, manual mobile money and balance sales all work offline, and they sync automatically when the connection returns. Only payment links need the internet.

02What devices do I need?

Any tablet or laptop with a modern browser. Opti Shop installs as an app from the browser (a PWA). Receipt printers and barcode scanners plug straight in.

03Where is my data kept?

Every client gets their own install and their own database. Nobody else's shop shares it. Scheduled backups go to cloud storage, and we test a restore with you before you go live. We follow Ghana's Data Protection Act and collect only the customer data you need.

04How are VAT, NHIL and GETFund handled?

Tax rates are settings, not code. Prices can include or exclude tax, and each product carries its rate. The tax report splits out each levy for filing.

05Can a cashier steal with discounts or voids?

Discounts have limits for each role. Voids, refunds, large discounts and price overrides ask for a manager PIN. Every sensitive action goes to the audit log, and the fraud watch report highlights patterns.

06Do I pay monthly or yearly?

Only for support and maintenance, and only if you want it. The licence itself is a single payment with no renewal. Support covers updates, fixes, backup checks and help, billed monthly or yearly. If you stop, nothing breaks: the system keeps working, you just stop getting updates and help until you restart.
