I appreciate that the Invoice Maker works offline and stores data on the device instead of uploading it online. The UPI QR, bank details, payment mode and paid or unpaid tracking make the invoice more complete.
The saved customer and product suggestions make repeat billing faster. I also liked the GST-inclusive rate option because the tool separates taxable value and tax from an inclusive selling price.
The invoice designs and Original, Duplicate and Triplicate copy options are useful for different business requirements. GSTIN validation and automatic state selection also help avoid basic entry mistakes.
Invoice history can be searched by customer or invoice number and filtered by payment status. The CSV export and backup-and-restore options are useful for keeping a separate record of the billing data.
The tool makes it easy to prepare both GST Tax Invoices and Bills of Supply. Item totals, discounts and the CGST, SGST or IGST split are calculated automatically, which reduces routine billing work.
