A GST invoice generator that starts from your paperwork
Most online bill makers give you an empty form. Populate.ai reads the document you already have — a supplier bill, a receipt, a handwritten pad page — and turns it into an invoice you can issue, print on A4, or send as a PDF with a UPI QR code attached.
The empty-form problem
Free invoice generators are plentiful and mostly identical: a blank template, a logo slot, a tax dropdown and a download button. They solve the last ten percent of the job. The other ninety percent is the typing — copying line items off a supplier bill, re-keying rates from a quotation, matching a payment received against three open invoices.
Populate.ai starts one step earlier. Extraction and issuance live in the same product, so the table the AI pulled out of a photographed bill becomes the line items of your invoice without a round trip through Excel. Cells the model was unsure about are flagged before the document is issued, not after a client queries it.
What you get
Invoices, bills and receipts in one place
Three document types that know about each other. A receipt records what settled which invoice; a bill records what you owe a supplier. Every issued document is versioned rather than overwritten.
UPI QR code on the invoice
For INR invoices, drop a UPI QR straight onto the document. The client scans, pays, and you mark it paid — no bank-detail typos in the middle of a payment.
GSTIN, HSN and custom tax lines
Capture your GSTIN and the client's, add HSN or SAC per line, and define your own tax fields for anything the standard slabs do not cover.
Recurring invoices and reminders
Retainer clients get their next draft generated on schedule. Overdue invoices get polite, logged reminder emails so you are not the one chasing.
One-click paid → receipt
Marking an invoice paid produces the matching receipt automatically and links the two, so your statement of account reconciles without manual matching.
A4 print preview and PDF email
A true A4 preview with no stray blank pages, plus send-as-PDF straight from the document. Statements export to CSV and XLSX.
What belongs on a GST invoice
Keep this checklist next to you the first few times. Populate.ai has a field for each of these; the responsibility for the values is yours.
- Supplier name, address and GSTIN
- A sequential invoice number and the date of issue
- Recipient name, address and GSTIN where registered
- HSN code for goods or SAC code for services, per line
- Description, quantity, unit, rate and taxable value per line
- Tax rate and tax amount, split as your supply requires
- Place of supply, and whether tax is payable on reverse charge
- Total in figures, and a signature or digital signature
Populate.ai formats and prints the document. It does not file returns, validate a GSTIN against the GST portal, or give tax advice — review each document before you issue it, and check anything unusual with your accountant.
Frequently asked questions
Is the invoice generator free?
Yes, you can create invoices on the free tier with monthly quotas on invoices, bills and receipts. Paid plans raise those quotas and unlock A4 print preview, part payments and read-only accountant access.
Does it produce a GST-compliant invoice?
You can capture your GSTIN, the client's GSTIN, HSN or SAC codes, place of supply and any tax lines you define — including custom tax fields for cess or state-specific levies. Populate.ai lays out and prints the document; it does not file returns or validate a GSTIN against the GST portal, so review the document before issuing it.
Can customers pay from the invoice?
For invoices raised in INR, Populate.ai can render a UPI QR code on the document so a client can scan and pay from any UPI app. You can also share a public pay link instead of attaching a PDF.
Can I invoice the same client every month automatically?
Yes. Recurring invoices generate the next draft on a schedule, and automated payment reminders chase unpaid invoices for you with a logged audit trail of every reminder sent.
What happens when the client pays?
Mark the invoice paid and Populate.ai generates the matching receipt and links it back to the invoice it settles. Part payments can be allocated across multiple open invoices on paid plans.
Can I generate an invoice from a bill I received?
Yes — that is the point of the product. Upload a supplier bill or a receipt, let the extraction pipeline read the line items, then convert the extracted table into an invoice instead of retyping it.
