Why retail & POS businesses choose Fast Billing Software

The billing headaches every
shop and store owner knows

The counter is slow when it matters most

At the busy hour, keying every item and price by hand holds up the queue. Customers wait, mistakes creep in, and a plain cash memo has no GST on it anyway.

Two systems for counter sales and corporate buyers

The quick POS bill lives in one tool and the GST tax invoice for a company buyer in another. Totals never tie out, and the same item is priced two different ways.

Day-end tally never matches the drawer

Counting cash, card and UPI by hand at close of day is guesswork. Nobody knows the real sales total, the GST collected, or which items actually moved.

Returns and accounts are a re-keying job

A customer returns an item and nobody adjusts the bill. At month-end every sale is typed again into the accounts, so GST filing is a scramble and figures don't reconcile.

How Fast Billing Software fixes each one
Scan, price and bill in secondsA barcode scan pulls the item, its price, HSN and GST rate straight in; take the payment and the thermal receipt prints — built for a busy counter, no manual typing.
One system for POS and B2BThe same counter prints a quick B2C receipt or a full GST tax invoice with the buyer's GSTIN, HSN lines and CGST/SGST/IGST — same item, same price, one place.
A day-end total that balancesClose of day shows sales total, GST collected, a cash/card/UPI payment-mode summary and item-wise sales, so the drawer and the books agree.
Returns handled, accounts postedA return raises a credit note that reverses the sale, and confirmed bills post to your accounts as sales vouchers with GST — works with Tally and other tools, nothing re-keyed.
Counter-to-books lifecycle

From a scan at the counter to posted books —
one bill carries the whole flow

Fast Billing runs the quick counter sale and the full tax invoice on the same engine — so scan, GST, receipt, payment, returns and your accounts are one connected flow, not five spreadsheets.

01 — Quick counter (POS) billing

Scan, bill and take payment at the counter

A busy retail counter needs speed. Scan a barcode and the item drops in with its price, HSN and GST rate; add a few more, take cash, card or UPI, and print the thermal receipt — the whole B2C sale in seconds. Barcode scanners, thermal (TSC) printers and POS hardware connect directly. See barcode & POS hardware.

02 — GST on every bill

The right GST on every sale, counter or corporate

Every bill carries GST — no separate cash memo that skips it. The system splits CGST and SGST for a local sale or applies IGST for an inter-state one, using the HSN code and rate mapped to each item. Freight or packing charges attach where needed, the total rounds and prints as amount in words, and your GSTR data reconciles at month-end. See GST tax invoicing.

03 — B2B tax invoices, same system

Full GST tax invoices for corporate buyers, no second tool

Some customers are companies buying on credit and they need a proper tax invoice — the same counter handles it. Capture the buyer's GSTIN, bill-to and ship-to, HSN item lines, CGST/SGST/IGST, other charges and amount in words, and print a full A4 invoice. Where goods are sent, a delivery challan or packing slip goes with them. See GST tax invoicing and delivery challans.

04 — Payments, returns & credit notes

Returns are reversed cleanly, dues followed up

A customer brings an item back and the sale is corrected — a credit note reverses the value and keeps the balance right, never a scribble in a notebook. Counter sales settle on the spot; credit customers get their receipts recorded against the bill, with advances adjusted and outstanding followed up. See credit & debit notes and payments & follow-up.

Close the day, then let it post to your books

At close of day you get the sales total, GST collected, a cash/card/UPI payment-mode summary and item-wise sales — and the invoice register by date and party. Confirmed bills post to your accounts as sales vouchers with GST, so nothing is re-keyed; it works with Tally and other tools. Dhruv AI adds plain-English sales trends and day-end insight summaries.

FAQ

Retail & POS billing software —
what shop owners ask us

Can I bill quickly at the counter with a barcode scanner?

Yes. Scan an item's barcode and the line is added with its price, HSN and GST rate from the item master, so a full B2C bill takes seconds. Scanners and POS hardware connect directly.

Does it print on a thermal (TSC) receipt printer?

Yes — the counter bill prints on a small thermal / TSC receipt printer, and the same system prints a full A4 GST tax invoice when a corporate or credit customer needs one.

Is GST charged on every bill?

Every bill carries GST. It splits CGST and SGST for a local sale or applies IGST for inter-state, using the HSN code and rate on each item, so your GSTR data reconciles.

Can I see day-end totals and a sales summary?

Yes — day-end sales total, GST collected, a cash/card/UPI payment-mode summary and item-wise sales, plus the invoice register. Dhruv AI adds plain-English sales trends.

Can I raise B2B tax invoices from the same system?

Yes. The same counter that prints a quick receipt also raises a full GST tax invoice with the buyer's GSTIN, HSN lines, CGST/SGST/IGST and a delivery challan where goods move.

Does it post to my accounts or Tally, and handle returns?

Confirmed bills post to your accounts as sales vouchers with GST — it works with Tally and other tools. On a return it raises a credit note that reverses the sale.
