Counter POS
One screen: search products, cart, customer, cash or bank payment. Amount fills from the total; credit sale is a single switch when they pay later.
Shop billing app — GST at the counter
GST billing for shops, sweet shops, and busy counters
Counter POS for rush hours — tap, pay, print. Full tax invoice when you need every line.
Whether you run a sweet shop, kirana, hardware counter, or wholesale desk, your team needs speed — tap products, take cash or UPI, print, next customer. Simple Bills is easy billing software on one screen: billing, payment, stock, and GST. Sell by weight? Decimal qty (kg/g) is built in. When you need detail, the full invoice screen is still there.
The daily headache we fix
Invoices in one notebook, UPI screenshots in WhatsApp, credit customers in your head — then month-end panic about who still owes money.
GST invoices in minutes
Create bills with products, discounts, and tax. Print or share — same data flows to your books.
Proforma invoices
Send a formal quote with PI numbering and a customer PDF. Stock and ledger stay untouched until you convert to a tax invoice.
Record payments when money lands
Partial or full payment against invoices — including when the customer deducts TDS. Customer ledger updates with no duplicate entry.
Sales returns without mess
Credit notes restore stock and adjust what the customer owes. Returns stay linked to the original sale.
Warranty replacement
Credit note plus replacement invoice at original rates — no cash refund; stock and balance stay correct.
Customer master & ledger
One place for contact details and running balance. Answer "kitna baaki hai?" in seconds.
Retail EMI loans
Sell on instalments against pending invoices — schedule, collect EMIs, and keep the customer ledger accurate.

Fastest single-screen POS for retail shops
Retail rush hours need one screen — not five tabs between billing, payment, stock, and GST. Counter POS keeps search, cart, customer, payment, and print on a single page so the next customer is not waiting.
- One screen, one flow — add items, take cash or UPI, save invoice and stock together
- Payment on by default — amount auto-fills from the total; flip to credit only when they pay later
- No separate POS app — same GST invoice, customer ledger, and month-end reports as your full billing
- Keyboard shortcut — Alt+Shift+B opens POS from anywhere in the app
- Retail-ready — decimal qty for kg/g, product grid for fast taps, last bill number for dispatch counters
Distributors invoicing linked buyers? See Connected Billing with connected ledger.
Counter POS — built for the busy counter
Most counter sales are paid on the spot. The POS screen keeps taps and typing to a minimum.
- Product search or tap-to-add grid — large catalogs stay fast
- Decimal quantity — sell 200 g when price is per kg; unit comes from the product
- Inline customer — pick existing or add name on the spot
- Payment on by default — amount auto-fills; switch to credit only when needed
- Cash or bank with UTR — first bank account selected for you
- Review once — then save invoice, stock, and payment together
- Last bill number on screen — billing counter and dispatch counter stay in sync
- Keyboard shortcut Alt+Shift+B from anywhere in the app
Proforma invoices — quote first, tax bill when they confirm
Need a formal estimate before the sale is final? Proforma invoices look like a real bill to the customer — without moving stock or posting to the books until you convert.
- Auto PI numbering — e.g. PI/25-26/000001, separate from tax invoice series
- Same products, GST lines, bank details, and amount payable on the PDF
- No stock reduction, customer balance, or payment entry on the proforma itself
- Excluded from GST filing totals until converted to a tax invoice
- One-click convert — prefills the sale invoice; stock and ledger update on confirm
- List, view, edit, print, and delete while still open (not yet converted)
