## GST

- **Tax invoices.** Every completed sale gets a GST tax invoice from its business’s own series, numbered without gaps per financial year (for example INV/26-27/00042). A B2B invoice carries the customer’s name, GSTIN and state.
- **Place of supply.** POSCountr compares the business’s registered state with the customer’s state — taken from their GSTIN where given — and applies CGST + SGST or IGST accordingly. Amounts use exact decimal arithmetic with invoice-level rounding.
- **HSN & SAC.** Each product and membership plan can carry an HSN or SAC code; it is saved onto the invoice line when the invoice is issued, so later product edits never alter an issued invoice.
- **Section 9(5).** For restaurant services sold through Swiggy or Zomato, the platform is liable for GST under Section 9(5): those lines carry no GST for you, packaged goods stay taxable, and the sale is recorded in a separate CH series. The GST report shows these figures for GSTR-3B.
- **GST reports.** Totals by rate, an HSN summary in GSTR-1 layout, B2B/B2C split and 9(5) figures for any date range, per business.
- **Accounts.** TallyPrime export and a statements workbook; a books lock freezes a filed period.

## Data and legal

- **Digital Personal Data Protection Act, 2023.** For owner and staff accounts, Aarvin Ventures is the Data Fiduciary. For customer details that a business records on its bills, the business is the Data Fiduciary and Aarvin Ventures processes them on its behalf, as set out in our Data Processing Terms.
- **Information Technology Act, 2000 and IT Rules, 2021.** We publish a Grievance Officer with contact details, acknowledge grievances within 48 hours and resolve them within the time the Rules allow.
- **Record keeping.** Invoices and the records behind them are kept for as long as GST law requires a business to keep them, even if an account is closed — and remain exportable by the business.
- **App store requirements.** Our apps publish a privacy policy, list every permission they use (camera for barcodes, Bluetooth for printers), and offer in-app account deactivation with a web page to request deletion.

## Questions

### Is POSCountr a substitute for my CA?

No. POSCountr produces correct invoices and the figures and files your accountant needs. You remain responsible for your product rates, codes and filings.

### Does POSCountr issue e-invoices (IRN) or e-way bills?

Not yet. E-invoicing is on our roadmap. Purchases can carry the supplier’s way bill as an attachment.

### Can I issue credit notes?

Not yet. A wrong bill can be cancelled and re-issued with “Cancel bill & copy” until the 10th of the following month; after that a credit note is needed and must be raised outside POSCountr for now.
