How to Make an Invoice for Online Sellers
What a practical invoice should include, how GST changes the layout, and how to keep records easier to audit.
Introduction
Invoice issues create confusion in settlements, returns and bookkeeping. Clean invoice habits reduce friction later with accountants, marketplaces and support teams.
What to check first
- Confirm invoice numbering, GST details and business identity fields.
- Match line items, tax values and totals against the actual order or shipment.
- Keep one repeatable layout for B2C and another if your workflow needs business invoices.
Step-by-step approach
- Set the invoice number format and tax fields before you create volume records.
- Review inclusive or exclusive GST logic before sending a customer copy.
- Store a PDF version and a sheet-based summary so future audits are easier.
Practical example
Use it in a real workflow
Start with GST Calculator when you want a faster working draft, then review the result against your actual workflow or marketplace requirement before publishing or printing anything important.
Common mistakes
- Sending invoices with correct totals but incomplete seller identity details.
- Mixing shipping, discounts and taxable value in a way that is hard to audit later.
- Saving only one copy in a chat thread instead of a structured record location.
