Which job comes first?
| If your day is mostly | You need | Examples of what to test |
|---|---|---|
| Sending GST invoices to businesses | An invoicing app | E-way bills, party balances, a CA login |
| A queue at the counter | A counter (POS) | Scan speed, loose goods by weight, one-tap payment, offline billing |
| Medicines | A counter with batches | Expiry refused at the sale, search by salt, strips and loose tablets |
| Books, returns and audit | Accounting software | Double-entry, filing, your accountant’s comfort |
Many shops use two: a counter for the day and accounting software with the accountant at month end.
The checklist
- Speed: scan 20 items in a row. Does it keep up?
- Loose goods: sell 750 g from a sack, or “₹50 worth”. Does stock follow?
- MRP: does it stop a line going above the printed price?
- Khata: who owes what, since when, and how do you remind them?
- Batches and expiry: does it sell the oldest first, and refuse what has expired?
- Purchases: a delivery raises stock and what you owe the supplier in one step.
- The drawer: does closing the day compare what should be there with what you count?
- No internet: does the counter keep billing, with real bill numbers?
- Staff: their own logins, and limits on discounts.
- Your data: can you take it away as a file?
The test: an hour at your own counter
- Load your own 50 fastest-selling items.
- Bill a real customer’s basket, with barcodes and something loose.
- Put a bill on khata, then take part of it back.
- Return one item from a paid bill.
- Record a delivery from your supplier, on credit.
- Print on your own printer.
- Cut the internet and bill for ten minutes.
- Close the day.
What it really costs
| Cost | What to ask |
|---|---|
| The plan | Per year, or one-time with a yearly charge? Is it per user? |
| Extra users | What does a second counter or login cost? |
| What the low price leaves out | Stock, reports, removing a watermark, support |
| The second year | What is the renewal, in writing? |
| Tax | Is GST on top? |
Published prices are side by side on the billing software comparison.
Red flags
- “Free download, full version” from a site that is not the maker’s: ask who supports it and where your data goes.
- No way to get your data out.
- A price with no period and no written renewal.
- A demo that never uses your own goods.
Setting it up, and the first month
- Load items from a spreadsheet, and start with what sells most.
- Count the shelf once.
- Enter what customers already owe you.
- Run it beside your current way for a few days.
- Count again after a week: the gap tells you where stock goes.
