GST compliance is mandatory as per Section 149 of the GST Act, 2017. Union Government is legally authorised to evaluate and rate every taxpayer (chemist and pharma companies) based on their performance in complying with mandatory GST rules and regulations. The new updates and tax rates announced in GST 2.0 (September 2025) also comes under this.
If you run a pharmacy business, GST compliance is mandatory. From correct tax calculation to timely return filing, even a small error can lead to penalties, notices, or blocked input tax credit. With thousands of daily transactions, manual GST handling is no longer practical for chemists.

What is Pharmacy Billing Software?
Pharmacy billing software is a specialised digital solution designed to manage billing, inventory, accounting, and taxation for chemist shops. Unlike generic billing tools, it is built to handle medicine-specific requirements such as batch numbers, expiry dates, drug schedules, and GST compliance.
Modern pharmacy shop software integrates GST rules directly into the billing process, ensuring every transaction follows the latest tax norms.
How Pharmacy Billing Software Ensures GST Compliance.
Accurate GST Calculation on Every Bill
Pharmacy retail billing software automatically applies the correct GST rate based on the product category. Whether it is branded medicines, generic drugs, surgical items, or FMCG products, the software calculates GST accurately at the time of billing.
This eliminates manual calculation errors and ensures customers receive GST-compliant invoices.
GST-Compliance Invoice Generation
A GST-compliant invoice must include mandatory details such as;
- GSTIN of seller and buyer (if applicable)
- Invoice number and date
- HSN code
- Taxable value, CGST, SGST, or IGST
- Total tax amount
Pharmacy billing software generates invoices in the exact format prescribed by GST authorities, reducing the risk of audit issues.
Automatic HSN Code Management
Correct HSN codes are essential for GST reporting. Pharmacy shop software like Marg ERP maps medicines and products with the appropriate HSN codes, ensuring accurate classification and reporting in GST returns. This is particularly useful for pharmacies dealing with thousands of SKUs.
Real-Time GST Reports and Returns
One of the biggest advantages of pharmacy billing software is real-time GST reporting. It automatically prepares:
- GSTR-1 (outward supplies)
- GSTR-3B (summary return)
- Purchase and sales registers
- Tax liability reports
This makes return filing faster, smoother, and less dependent on manual data compilation.
Input Tax Credit (ITC) Tracking
Pharmacy billing software records purchase GST details accurately and helps track eligible input tax credit. It also assists in matching purchase data with supplier invoices, reducing ITC mismatches. This ensures pharmacies claim the right credit and avoid unnecessary tax loss.
Error Reduction and Audit Readiness
Since all data is stored digitally and updated in real time, pharmacies remain audit-ready at all times. Reports can be generated instantly for internal checks or GST department audits. This level of accuracy and transparency is difficult to achieve with manual systems.
