"Before KeeSpark, our sales reps generated estimates in Word, accounts created proformas, and billing typed sales invoices into Tally. It was a disaster of manual mistakes. With KeeSpark, the Proforma ➔ UPI Payment ➔ GST Sales Invoice flow happens in 1 click. We recover payments in 12 days instead of 45 days."

Frequently Asked Questions About KeeSpark Invoice
Everything you need to know about GST compliance, proforma workflows, UPI payments, and modular expansion.
A Proforma Invoice is a preliminary pre-sales quote or estimate. It allows the buyer to review pricing, payment terms, and HSN codes prior to delivery without triggering statutory GST output tax liabilities for your business. Once the customer pays or confirms, KeeSpark allows you to convert the proforma into an official GST Sales (Tax) Invoice in 1 click, generating the required IRN e-invoice QR code and updating accounting ledgers.
