Counter and B2B
Bills, collections and B2B
Walk-in payment, hospital credit, GST bill. No doctor commission.
Walk-in GST documents are Starter. B2B ledger, credit block, franchisee settlement, and payers are Clinic.


Three lab modes
Not registered: a plain invoice, no tax column. Registered and mostly exempt: bill of supply. Registered and taxable: tax invoice with every Rule 46 field.
- CGST+SGST or IGST from place of supply
- Series unique per financial year, reset 1 April
- Issued bills are never edited — void same day, else a credit note
- GSTR-1 shape and Tally export
B2B without doctor cuts
Hospitals, clinics, lab-to-lab, and franchisee collection centres keep a running ledger. Establishment-to-establishment settlement is allowed. A payout field for a referring doctor is not a feature and will not become one.
- Credit limit and block
- Monthly statements and receipts
- Franchisee keeps its cash, settles the transfer price
- Payers and scheme rate lists on Clinic
