PVC billing for Indian Railway contractors

Price variation bills that survive audit.

TenderAudit turns your agreements, running bills and published RBI/JPC indices into deterministic, audit-ready PVC claims under GCC Clause 46A — replacing the fragile Excel workbooks your billing depends on today.

Verified to the paisa against real submitted PVC workbooks.

per PVC bill, from transcription and averaging to export

Zero silent defaults

runs block on missing eligibility decisions instead of guessing

Clause 46A native

GCC price variation rules encoded, not re-derived per engineer

Built for the way Railway billing actually works

Not a generic invoicing tool — a vertical billing OS for the PVC chain: agreement, schedules, MB, running bills, recoveries, indices.

Deterministic PVC engine

Component-wise Clause 46A calculation with fixed rounding rules. The same inputs always produce the same paisa — verified against real submitted workbooks.

Explicit W derivation

Cement, steel buckets, technical withheld and extra-item exclusions are named, confirmed steps. A run blocks on a missing decision — it never assumes.

Rolling quarters, done right

Quarters anchor to the contract's base month, not the calendar. Index averages use the correct three-month window for every bill's measurement date.

Immutable approved runs

An approved run is frozen with its inputs snapshotted. Corrections create a superseding run — the audit trail never rewrites itself.

Excel-parity export

The export matches the submission format Railway field accounts already expect — native numeric cells, live totals, familiar column order.

Seeded index master

RBI and JPC index history since 2022 is pre-loaded. Add each new month once and every affected contract picks it up.

From contract file to submission pack

01

Set up the contract

Agreement, LOA, base month, schedules, component weights and the applicable GCC clause — captured once, validated up front.

02

Enter bills and recoveries

Running bills, recovery sheets and monthly indices go in as structured data with carry-forward handled automatically.

03

Run, approve, export

The engine computes the claim, a reviewer approves it, and you export the submission pack — every number traceable to its source.

Stop rebuilding the same workbook every quarter.

Set up a contract once and every PVC bill after that is computed, reviewed and exported from the same auditable source of truth.
