Credit

Sell on Baki without losing track

A credit sale posts to the customer ledger immediately. Take partial payments later against one or many invoices, see who is overdue, and send a statement as a reminder.

Barcode scanning

Scan the pack, and the bill is done

PharmaOS works with the barcode scanner you already have. Here is what happens from the scanner to the invoice.

  1. A barcode scanner reads a medicine pack and the item appears on the bill

    Scan at the counter

    Plug in any USB or Bluetooth barcode scanner; it types into the POS like a keyboard. The code is looked up instantly and the line lands on the bill with the earliest-expiring batch. No match? The same box searches by name, salt or brand.

  2. A medicine pack showing its barcode, batch number and expiry date, matched to a product in the catalogueBatch MLC2405Exp 08/20278 901234 567890

    One product, several barcodes

    A product can hold more than one barcode, each tied to a unit, so the strip and the box of the same medicine scan as 10 tablets or 1 box. Batch number, expiry and MRP come from the pack when you enter the purchase, not from the barcode.

  3. Barcode labels printed from the product page and stuck on loose itemsPH-000412PH-000413

    Print labels for the rest

    Loose items, repacks and products without a manufacturer code get a label printed from the product page, so everything on the shelf scans the same way.

Common questions

Can I scan medicine barcodes?

Yes. The point of sale searches by barcode, product name, generic name or brand. Any USB or Bluetooth barcode scanner that types into a field works; there is nothing extra to install.

Can I sell loose tablets?

Yes. Each product defines its units and conversion (for example 1 strip = 10 tablets) and stock is kept in the smallest unit. You can bill 3 tablets from a strip and the stock stays exact. Loose sale can be switched off per product.

Does the system support GST?

Yes. GST is built in for India: CGST/SGST or IGST is decided by place of supply, HSN codes and GSTIN print on invoices, and there are GST summary reports for filing. The tax engine is modular so other regimes can be added.

Can I manage customer Baki (credit)?

Yes. Known customers can buy on credit within a limit you set. Every credit sale, partial payment and adjustment goes into the customer ledger, so outstanding, overdue amounts and statements are always reconciled. Reminders can be emailed with the statement attached.

Can I generate PDF invoices?

Every sale, return, purchase, GRN, payment receipt and customer statement can be printed or downloaded as a PDF, emailed to the customer, or shared as a WhatsApp-ready link.

What happens if the internet drops at the counter?

The bill being typed is kept on the device and restored after a refresh or reconnection. Completing a sale needs a connection, and every submission carries an idempotency key so a retry never creates a duplicate invoice or deducts stock twice.
