How to use Bill Minutz

Written the way you would ask about it: what to do first, where each thing lives, and what to do when something does not look right. If your answer is not here, write to us and a person will reply.

Covers the software as it works today, 27 October 2026

1. Start here

Five things, and you can bill. Most shops are done in under twenty minutes.

  1. Create your account. You will be sent a code by SMS to confirm your mobile number. That number, or your email, is how you sign in afterwards.
  2. Fill in the business profile. Admin → Settings: your name as it should print, GSTIN, address, state, bank and UPI details, logo and signature. The state matters — it decides whether a bill charges CGST and SGST or IGST.
  3. Add what you sell. Masters → Products & Services. Give each one its HSN or SAC code and its GST rate once, and every bill after that is correct by itself.
  4. Add your customers and suppliers. Masters → Customers and Suppliers — or just type a new name while you are making the bill and it will be saved for next time.
  5. Raise your first invoice. Sales → Sales Invoices. Pick the customer, add the items, and print, download or send it on WhatsApp.
Your free trial is the whole product, not a cut-down version. The one limit is the AI bill scanner, which reads 5 supplier bills during the trial; typing bills in by hand is unlimited.

The menu follows the order a business actually works in, not alphabetical order. Click a heading and it folds open. A section you have no use for stays shut, and anything your plan does not include is not shown at all.

Everything else

On a phone the menu is behind the button at the top left, and the pages are built to be used one-handed.

3. Invoices and documents

Each kind of document has its own running number and its own print layout, and one can be carried into the next so nothing is typed twice.

DocumentWhat it is for
QuotationA price you are offering. No effect on stock or books.
EstimateA working figure for a job before it is confirmed.
Proforma invoiceA bill-shaped document sent to get an advance or an approval. Not a tax invoice.
Sales invoiceThe tax invoice. This is what charges GST, moves stock and enters your books.
Delivery challanGoods going out without a bill yet. Turn it into an invoice when you bill it.
Credit noteA return or a reduction against an invoice you already raised, with the GST reversed.

4. GST

GST is worked out for you from three things: your state, your customer, and the rate on the item. You do not calculate anything by hand.

Which tax goes on the bill

Input credit on what you buy

Record the supplier's GSTIN, or the GST is not credit. On a purchase or an expense, GST counts as input credit only when the supplier's GSTIN is on the record. Without it, the law treats that GST as part of the cost, and so do we — it will show in your costs instead of reducing your GST bill. This is the single most common reason a GST figure is not what an owner expected.

Returns and filing

Why a figure may look odd

We can tell you what the software does. For the rules themselves — registration limits, due dates, what is exempt — the authorities are gst.gov.in and cbic.gov.in, and for anything unusual, your own CA knows your case.

5. Products and stock

6. Purchases and suppliers

7. Money in and money out

8. Service jobs and AMC

These two appear for a business that does work, not only one that sells goods.

9. Staff logins

10. Reports and books

Nothing to post. The Day Book, Ledger and Cash & Bank Book are built from your own bills, receipts and payments every time you open them. There are no journal entries to pass, and the books cannot fall behind the documents — they are the same numbers, shown differently.

11. Your account, plan and data

12. When something goes wrong

I forgot my password

On the sign-in screen choose "Forgot password". A link is emailed to the address on the account and it works for 30 minutes. Opening it signs out every other session, which is deliberate: if someone else knew the password, they are now out.

A staff password is not reset by email — the owner sets a new one from Team → Staff & Technicians.

The SMS code has not arrived

Check the ten digits you typed, then wait for the timer to finish before asking again — asking repeatedly does not make it faster. A code is only needed when you create the account, not every time you sign in.

If it still does not come, write to us with the number and we will confirm the account by hand.

It says my plan has ended

Renew in Admin → Subscription. Your data is untouched and nothing has been deleted — the screens unlock the moment the payment goes through.

A page or menu item is missing

Two possible reasons. If you are the owner, that feature is not in your plan — Admin → Subscription shows what each plan includes, and some features can be added on their own. If you are staff, the owner has not given you that page; ask them to tick it in Team → Staff & Technicians.

I was signed out suddenly

A session lasts a week. It also ends early, on purpose, if the password was changed, the login was switched off, or the owner removed it. Sign in again; nothing is lost.

A report shows a number I do not agree with

The books are built from your documents, so the figure is always traceable. Open the report, follow the line back to the bill or receipt behind it, and the cause is usually one of these:

  • A purchase or expense with no supplier GSTIN, so its GST is in cost instead of credit (see GST).
  • An estimate or a proforma mistaken for an invoice — neither one enters the books.
  • A date in the wrong month, which moves the entry to another period.
  • A credit note not yet raised for a return.

If it still looks wrong, send us the bill number and what you expected. A wrong figure is a bug we want to know about.

A bill will not send on WhatsApp or email

Check the channel in Settings: messaging can be off, can go through the Bill Minutz account, or can go from your own WhatsApp Business account or your own mailbox. If you use your own, the credentials there must still be valid.

Also check the customer's number or email on the customer record — a missing country code or a typo is the usual cause.

The bill scanner says I have used my scans

The free trial includes five scans, because each one costs us an AI reading. Choose a plan, or add Bill Scan on its own, in Admin → Subscription. Entering bills by hand is never limited.

A bill the scanner could not read does not use up a scan.

I deleted something by mistake

Admin → Recycle Bin. Deleted records wait there for 60 days and can be restored. Admin → Edit History shows changes rather than deletions — who edited which document, and when.

13. Ask us

If the answer is not here, ask. We would rather answer the same question twenty times than have you guess at your own books.

Support, inside the appAdmin → Support

The best route once you are signed in: we can see which business and which bill you mean, so there is nothing to explain twice.
