Billing & Invoicing Applications
GST-compliant billing and invoicing applications that generate accurate invoices, e-invoices and payment links quickly, then track what is owed so cash comes in on time.
Overview
Why it matters
for your business.
Invoices typed in Excel lead to wrong tax rates, missing HSN codes and duplicate numbers, and chasing payments becomes a full-time job. For businesses above the e-invoicing threshold, manual processes also mean extra effort uploading to the IRP. We build billing and invoicing applications that produce correct, branded invoices in seconds and follow them through to collection.
We configure tax rules, numbering series and templates for each of your GSTINs, then connect to the e-invoice and e-way bill systems through a GST Suvidha Provider or direct APIs. Invoices can carry UPI QR codes and payment links, and receipts reconcile automatically. Recurring billing, credit notes and customer statements are included, with exports for your accountant or a sync to Tally or Zoho Books.

FAQ
Common
questions.
Something else on your mind? Ask us directly.
Is the application suitable if we are not yet required to issue e-invoices?
Yes. The system produces standard GST invoices today, and e-invoicing can be switched on when your turnover crosses the applicable threshold. Because data is already structured correctly, enabling IRN generation later is a configuration step rather than a rebuild.
Can customers pay directly from the invoice?
Yes. Each invoice can include a UPI QR code and a payment link through a gateway such as Razorpay or Cashfree. When a payment succeeds, it is recorded against the invoice automatically, and the customer receives a receipt, reducing manual matching of bank entries.
