Use Case: Cleaning Up GST Billing Across a Mixed B2B and B2C Counter
See how a pharmacy uses RxPlix to eliminate GST billing errors across mixed B2B and B2C sales, with clean credit notes and payment tracking.
The Problem: Two Kinds of Customers, One Error-Prone Billing Process
A busy retail pharmacy serves two very different kinds of buyers over the course of a day — individual walk-in customers paying MRP, and a handful of B2B accounts (a nearby nursing home, a small clinic buying in bulk) that require GST calculated forward from the base price rather than back-calculated from MRP. For months, the same billing counter handled both types of sales using one generic invoice format, with staff manually adjusting GST treatment based on memory of which customer was which.
The result: recurring GST mismatches, a nursing home account disputing an invoice over incorrect tax treatment, and a pharmacist spending hours each month trying to reconcile which bills were calculated correctly.
The Scenario: A Pharmacy Serving Retail and Institutional Customers
The pharmacy processes roughly 150 retail transactions a day, alongside 3–4 larger B2B orders per week from institutional buyers. Each transaction type needs fundamentally different GST handling, but the billing process treated them identically — leaving GST accuracy entirely dependent on whichever staff member was at the counter remembering the right approach.
How RxPlix's Sales & Purchase Management Solves This
Configure Transaction Types Correctly
The pharmacy sets up its institutional accounts as B2B customers inside RxPlix, while retail walk-ins default to standard B2C billing — so the GST calculation method is determined automatically by the transaction type, not by staff judgment.
Bill Retail Sales with Back-Calculated GST
For everyday retail sales, RxPlix automatically calculates GST backward from the MRP, ensuring the price displayed and charged to walk-in customers matches exactly what they expect to pay.
Bill B2B Sales with Forward-Calculated GST
For the nursing home and clinic accounts, RxPlix applies forward-calculated GST from the base price — generating invoices that are correctly structured for the buyer's own input tax credit purposes.
Handle a Return with a Proper Credit Note
When the nursing home returns a partial order due to an overstock issue, the pharmacy issues a structured credit note directly against the original invoice — automatically correcting both the GST record and the inventory count, with no manual adjustment required.
Track Payment Settlement
Because the institutional account pays on a 15-day cycle rather than at time of sale, RxPlix tracks the invoice as pending until settlement, with a payment voucher generated once payment is received — giving the pharmacy clear, real-time visibility into what's actually outstanding.
The Outcome
GST disputes with institutional buyers stop entirely
because every B2B invoice is now correctly structured by default.
The pharmacist reclaims hours each month
previously spent manually reconciling GST treatment across transaction types.
Outstanding B2B payments are visible in real time
rather than tracked in a separate notebook that was easy to lose track of.
Why This Matters for Any Pharmacy Serving Mixed Customer Types
Any pharmacy selling to both individual customers and institutional buyers faces this exact risk — and the fix isn't more staff training, it's removing the decision from manual judgment entirely.
