Charging Incorrect GST Rate

Different metal drilling machines may have different GST rates. Always check the correct rate before billing.

Not Mentioning Complete Product Details

Bills must include full product specifications, like type, model, and features. Vague descriptions can cause confusion or disputes.

Missing Serial Numbers or Machine IDs

For high-value machines, not mentioning serial numbers may affect warranty and tracking.

Ignoring the SAC Code in Case of Services

If installation or servicing is included, make sure to use the right SAC code for services in the same invoice (if applicable).

Not Updating the GSTIN of the Buyer

Skipping Delivery and Transport Details

Not adding transport mode, delivery address, or e-way bill info can delay logistics or violate compliance rules.

Wrong Tax Split (CGST/SGST vs IGST)

Not identifying whether the sale is intra-state or inter-state can lead to the wrong tax application (IGST vs CGST+SGST).

Not Including Warranty or AMC Info

If a warranty or AMC is offered, it should be clearly mentioned in the bill to avoid future conflicts.

Forgetting to Sign or Stamp the Invoice

Unsigned or unstamped invoices are considered incomplete, especially for B2B transactions.
