How to start computer billing in your shop in one day
A practical checklist for moving a small shop from a notebook or calculator to computer billing.
1. Decide what goes on the bill
Write down your shop name, address, phone and, if you are GST-registered, your GSTIN. Pick a short invoice prefix (for example your shop’s initials) so bill numbers are easy to read.
2. List your top products first
You don’t need every item on day one. Start with the 50–100 items you sell most, with selling prices. Loose items need a unit (kg, g, l). Add the rest as they come to the counter.
3. Count opening stock
Enter today’s quantity for each product. It doesn’t have to be perfect — later corrections are recorded as adjustments, so you can always see what changed and why.
4. Give staff their own logins
Invite each cashier with their own account. Cashiers can bill but can’t see costs or profits, and every bill shows who made it.
5. Close the day
At closing time, count the cash drawer and record it. The difference between expected and counted cash tells you early if something is wrong.
