What determines the quotation?
For e-invoice billing software, the quote should follow actual scope—not a generic per-page or per-screen rate. The starting problem is often that invoice details need extra checking before IRN workflows. Complexity increases when the solution must coordinate more people, controls or integrations.
Core work to estimate
- Invoice capture
- Gstin and hsn validation
- Irn submission integration planning
- Qr and status capture
- Reconciliation
Optional work that changes budget
Migration of old records, external integrations, advanced permissions, multiple entities, multilingual content, specialized reports, video revisions or custom deployment processes should be listed separately if relevant.
Deliverables to include in a proposal
- Irn status
- Error log
- Invoice history
- Tax review
Questions to put to a vendor
Costly problems to avoid
- Current gst applicability
- Credential security
- Provider integration
How to compare proposals fairly
Ask at least two vendors to price the same scope, examples and support period. Avoid assuming that a very long feature list offers value. Define whether success will be assessed by rejected invoice count or by another measurable outcome.
A written project brief and a demonstration are more useful than claims such as 'best' or guaranteed results.
