Three Engines Behind Effortless Invoicing
Every invoice created in OneFinOps is compliant, branded, and traceable from send to payment.
Smart Invoice Templates
Create reusable templates for your most common services. Customer profiles store GSTIN, billing address, payment terms, and preferred currency. One click populates the entire invoice, you just review and send.
- Customer master with GSTIN and credit terms
- Service/product catalogue with HSN/SAC codes
- Recurring invoice scheduler (weekly, monthly, quarterly)
- Multi-currency support with INR conversion
GST Calculation & E-Invoice IRN
OneFinOps automatically applies the right GST rate based on HSN/SAC code and customer state. CGST+SGST for intra-state, IGST for inter-state. For businesses above the e-invoicing threshold, IRN and QR codes are generated inline via NIC API.
- Auto CGST/SGST/IGST split based on supply type
- TDS deduction at source for eligible transactions
- IRN generation via NIC e-invoice API
- QR code embedded in PDF per GST mandate

From Creation to Collection in Five Steps
Every invoice follows a clear, traceable path, no more chasing status updates
Draft
Select a customer from your master list. OneFinOps auto-fills GSTIN, billing address, payment terms, and credit limit. Add line items from your service catalogue. HSN/SAC codes are pre-mapped. Taxes calculate instantly as you type.
Validate
Before saving, OneFinOps validates the customer GSTIN against the GST portal, confirms HSN/SAC codes, and checks whether e-invoicing is required based on your annual turnover. Errors are flagged inline before any PDF is generated.
Generate IRN
For eligible businesses, OneFinOps submits invoice data to the NIC e-invoice portal via API and retrieves the IRN and QR code in seconds. The signed QR is embedded in the PDF automatically, no manual portal login required.
Send
The finalized invoice is sent as a branded PDF via email, WhatsApp, or a secure shareable link. Each delivery includes a Pay Now button that supports UPI, NEFT/RTGS, and cards. Bulk send up to 100 invoices at once for month-end billing runs.
Track & Collect
Monitor invoice status in real time, sent, opened, partially paid, or overdue. Overdue invoices automatically enter your collections sequence. When payment arrives, it's auto-matched and the invoice is closed with a full audit trail.
