Lab billing
Billing that holds up at the counter and at month-end.
Phone-first lookup, sequential bill numbers, rupee-perfect totals, and every discount or refund carrying a staff member's name. Nothing to reconstruct later.
Key takeaways
- Phone number first. A returning patient is found and re-used, not registered again under a slightly different spelling.
- Every discount and refund carries a name. Both are audit-logged with the staff member who gave them, at the moment it happened.
- Bills are gapless and rupee-perfect. One sequential number per financial year, every amount stored as integer paise.
- Taxable bills carry a GST-compliant invoice. Your lab’s own GSTIN, the relevant HSN/SAC codes and a full CGST/SGST/IGST breakup, printed right on the bill.
- Partial payment doesn't stall a bill. What's paid today is recorded, and the rest moves into aging receivables.
- The bill still closes without a report. A films-only close is money-neutral and reversible until the report is finalized, and it fires no WhatsApp message.
What is lab billing software?
Lab billing software is the system a diagnostic lab uses to register a patient, bill them for tests, and issue a GST-compliant invoice, in place of a cash register and a paper ledger. HealthFlow's version runs the counter end to end: pull up a patient by phone number before a duplicate gets created, bill in seconds, and every discount or refund is audit-logged with the staff member's name who gave it. Bills are numbered in a single sequence for the financial year, every amount is stored as whole paise, and a bill doesn't have to be paid in full or matched to a finished report to close: partial payments move the balance into receivables, and a test the patient declines a report for can be closed films-only, money-neutral. For the supplies on a bill that are taxable, the same bill carries a GST-compliant tax invoice: the lab’s GSTIN, HSN/SAC codes and a CGST/SGST/IGST breakup. Every bill can also go out on WhatsApp, tracked to delivered and read.
Start from the phone number
One lookup finds the patient. Every rupee off the bill has a name on it.
A phone number is the fastest, most reliable way to find a returning patient, so that's where billing starts. And because discounts and refunds are where trust quietly erodes at a busy counter, neither one happens without a record of who gave it.
- Phone-first lookup: a returning patient is found and re-used, not registered a second time under a slightly different spelling
- Every discount and refund audit-logged with the staff member's name, at the moment it's given
- Every rupee stored as integer paise, split across cash and online without drifting over a busy day
Money that doesn't go quiet
Bills in strict order. Dues that never disappear.
Bill numbers run in a single sequence through the financial year, so nothing gets renumbered by hand later. And a bill isn't all-or-nothing: if a patient pays part of it now, the rest becomes a tracked due, not a gap in the register.
- Sequential, fiscal-year bill numbering: one running series, no gaps, no duplicates
- Partial bills: record what's paid today, and the balance moves straight into receivables
- Receivables aging on the outstanding balance, so a due doesn't quietly go stale
The bill still closes, even without a report
Share the bill on WhatsApp. Close it films-only when there's no report.
A bill reaches the patient's phone the same way the report does. And when a patient only wants their films, not a printed report, that test closes on the bill as films-only: money-neutral, and reversible right up until the report would have been finalized.
- WhatsApp bill sharing from the lab's own number, tracked sent → delivered → read
- A test can be closed films-only when the patient declines the report; the bill's amount doesn't change
- Films-only closes are reversible until the report is finalized, and fire no WhatsApp message
Your bill is ₹1,050, paid in full. X-Ray Chest handed over as films only, per your request; amount unchanged. Thank you for visiting Lotus Path Labs.
A compliant invoice, not extra software
A GST-compliant tax invoice, right on the bill.
Much routine diagnostic testing is commonly treated as exempt (confirm the treatment for your billing structure with your accountant). For the supplies on a bill that are taxable, HealthFlow prints your lab’s own GSTIN, the relevant HSN/SAC codes and a full CGST/SGST/IGST breakup right on the bill itself.
- Your lab’s own GSTIN and the relevant HSN/SAC codes printed on every taxable invoice
- A full CGST/SGST/IGST breakup, calculated and shown line by line
- HealthFlow issues the compliant invoice; it does not file your GST returns
Questions
Does the bill start from a phone number, and does that stop duplicate patient records?
Yes. Billing starts with a phone-number lookup, so a returning patient is found and re-used instead of registered again under a slightly different spelling. Everything the lab already knows about them, history and dues included, comes up before a single test is added to the bill.
Are discounts and refunds tracked, and can I see who approved one?
Every discount and refund is audit-logged with the staff member's name at the moment it's given, not reconstructed later from memory. Amounts are stored as integer paise throughout, so a busy day of split cash-and-online payments never drifts by a rupee.
What happens to the bill if a patient only wants films, not a report, or can't pay the full amount today?
Both are handled without breaking the bill. A test can be closed as films-only when the patient declines the report; it's money-neutral and reversible until the report is finalized, and no WhatsApp message fires for it. And a bill doesn't need to be paid in full to close: record what's paid now, and the balance moves straight into receivables, aging until it's cleared.
Does HealthFlow generate GST-compliant tax invoices, and does it also file my GST returns?
It generates the invoice, not the return. For the supplies on a bill that are taxable, HealthFlow prints your lab’s own GSTIN, the relevant HSN/SAC codes and a full CGST/SGST/IGST breakup right on the bill itself. Much routine diagnostic testing is commonly treated as exempt; whether that applies to your billing structure is a question for your accountant, not the software. HealthFlow does not file GST returns on your behalf, it issues the compliant invoice.
Lab billing software ka price kya hai, aur kya GST invoice banta hai?
HealthFlow lab billing starts at Rs 399 per month and produces GST-compliant tax invoices with your lab own GSTIN, HSN/SAC codes and a full CGST/SGST/IGST breakup, with sequential fiscal-year bill numbers.
