fast cashiering
A till that keeps up with your busiest hour.
Long queues cost sales. LinearPOS is built around the fewest possible taps, so a cashier can serve one customer and be ready for the next without touching the mouse.
- One screen, one flow. Items, totals, customer and payment all sit on a single checkout screen.
- Keyboard-friendly. Scan, set a quantity, tab to payment and finish the sale from the keyboard.
- Hold and recall. Park a sale when a customer runs back for one more item, serve the next person, then bring the first bill straight back.
- Discounts at the till. Apply promotions and line or bill discounts in a tap, with approval rules for the ones that need a manager.
- Instant receipts. Print on a thermal printer, or send by email or SMS, the moment payment clears.
Barcode & Item Search
Scan it, or just start typing.
Barcodes make the queue fly, but not every item has one. LinearPOS gives your cashiers both routes, and both land on the same bill.
- Works with any barcode scanner. Scan and the item is added and priced without a single keystroke.
- Search as you type. Find items by name, brand, code or SKU, and see price and stock before you add them.
- Sizes, colours and variants. Pick the right 350ml or the right shirt size from one search, without hunting through lists.
- Live stock at the till. Cashiers see what is on the shelf, and every sale updates inventory automatically.
Multiple paymodes
Customers pay their way. You see one clean total.
Accept every payment method your shoppers use, on the same bill, and let LinearPOS keep each one separate for reconciliation at the end of the shift.
Cash
Enter the amount tendered and the change due appears instantly. Cash is tracked per cashier shift.
On Account
Sell on credit to approved customers and track what each one owes, with limits you control.
M-Pesa
Send a payment prompt to the customer's phone, or match a payment to their till. Confirmed payments close the sale.
Credit & Debit Cards
Record card payments against the sale with a reference, so card totals match your settlement reports.
Multiple paymodes
Mobile money, connected to the bill.
No more reading out transaction codes or scrolling through SMS messages. Payments made through M-Pesa and Kopo Kopo come straight into LinearPOS.

It comes straight into LinearPOS, with no manual entry.
3
Sale is matched
Recorded against the bill and included in your shift and sales reports.
KRA eTIMS integration
Compliance that happens at the till, not after closing.
Under eTIMS, tax invoices have to be validated with KRA, and the customer's receipt has to carry the proof. LinearPOS does it for every sale, in the background, so your cashiers never have to think about it.
1
Cashier completes the sale
Items, tax codes, buyer PIN (when the customer gives one) and paymodes are all captured in the normal flow. No extra buttons.
2
Invoice is transmitted to KRA
LinearPOS formats the invoice to KRA's eTIMS specification and submits it in real time.
3
KRA validates and responds
KRA returns the QR code and invoice number (CUIN) that make the invoice verifiable.
4
Receipt prints with proof
Your PIN, the total, the QR code and the invoice number print on the receipt. The customer can scan to verify it.
Receipt prints with proof
Your PIN, the total, the QR code and the invoice number print on the receipt. The customer can scan to verify it.
Works when the internet drops
Keep selling through an outage. Invoices are queued and can be submitted once you are back online.
Credit notes and returns
Refunds and corrections are issued as proper credit notes linked to the original invoice.
Item and tax classification
Product codes and tax rates are set once on the item, then applied correctly on every invoice.
Know what a valid receipt looks like
KRA says a valid eTIMS receipt shows the supplier PIN, a QR code and the total amount. An M-Pesa SMS proves payment, but it does not replace the tax invoice, so every sale still needs one.
Setup and training includes connecting your business to eTIMS, so your first sale is already compliant.
Everything around the sale
More than a till. A complete sales and billing desk.
Retail is not only walk-in sales. LinearPOS also covers the quotes, invoices, returns and controls that keep a growing business in order.
Professional invoicing
Issue itemised invoices with your logo and business details in a few taps, for walk-in and business customers alike.
Hold and recall sales
Park any bill and bring it back later, from any till, without losing a line item.
Cashier shifts
Open and close shifts with float and cash-up, and see a clear report for each cashier.
Discounts and promotions
Line or bill discounts, offers and price lists applied at the till, with manager approval where you want it.
Returns & Credit Notes
Take items back, refund by the right paymode and issue a credit note that stays linked to the original sale.
Receipts your way
Thermal receipts or A4 invoices, all carrying your branding.
Users, Roles & Approvals
Give each person the access they need. Voids, refunds and price overrides can require a manager.
Live Sales Report
See sales by cashier, item, paymode and day as charts and tables, updated as you sell.
Tax handled for you
VAT is calculated on every line and kept in your records, ready for returns and your accountant.
Cashier shifts
Close every shift with the numbers matching.
Each cashier opens a shift with a float and closes it with a count. LinearPOS shows what the till should hold, per paymode, so differences are caught the same day and traced to the shift that caused them.
- Opening float, cash in and cash out recorded against the shift
- Expected versus counted totals for cash, M-Pesa and cards
- Printable shift and end-of-day reports for the manager
- Role-based access, so only managers can void, refund or override prices
