Sri Lanka B2C E-Invoicing and POS Readiness: Retailer Checklist

B2C e-invoicing changes the POS from a till that prints a receipt into the front door of the retailer's tax and finance system. A store can have a modern-looking checkout and still be unprepared if product tax codes, invoice serials, returns, and stock movements do not agree.

The five readiness checks

1. Every SKU has a controlled tax category and unit of measure.
2. Invoice numbering is centralised, sequential, and protected from duplicate offline devices.
3. Returns and credit notes reverse the original sale instead of creating unexplained adjustments.
4. POS sales post to inventory and finance without nightly spreadsheet re-entry.
5. The business can reproduce the source transaction and its edits for an audit or reconciliation.

Where retailers usually fail

The common failure is not the printer or payment terminal. It is inconsistent master data: the same item has different names, tax treatment, or units in the POS, inventory file, and accounting package. Fix the item and customer master first, then test sale, refund, discount, exchange, and day-end settlement scenarios.

Use this checklist alongside the Sri Lanka VAT e-invoicing ERP guide and the POS and inventory integration guide. For a readiness review, contact Capricon.
