RA Billing Built on Certified Quantities, Not Guesswork

Running Account bills pulled from actual certified BOQ progress, with retention posted as a real ledger entry — so outstanding amounts and retention receivable are always visible, not reconstructed at collection time.

Key Takeaways

  • RA bills generate from certified quantities against BOQ line items — not a manually re-compiled summary disconnected from what was actually measured and approved.
  • Retention is posted to its own ledger account (Retention Receivable) at the point of billing, not just stored as a percentage on the bill header — so outstanding retention is always visible as a real number, not something reconstructed later.
  • GST-compliant invoicing and e-way bill generation are part of the same billing flow, connected to the same underlying data.
  • This module is core and mature — connected directly to the BOQ and Measurement Book, not a standalone invoicing tool disconnected from project progress.

A common gap in construction billing: retention gets subtracted as a percentage line on the invoice, but is never tracked afterward as an actual receivable — so nobody has a clean running total of how much retention is currently locked up across all active projects until someone manually compiles it. Rebota's RA billing posts retention to its own ledger account at the point of billing, so that number is always current.

Billing from certified quantities

RA bills pull from the same Measurement Book data that BOQ and site execution feed — certified quantities against BOQ line items, not a manually assembled bill that has to be cross-checked against site records separately. GST-compliant invoicing and e-way bill generation happen in the same flow.

Which One Should You Actually Use

Who Should Use Rebota

Contractors currently billing from manually compiled spreadsheets, with retention tracked only as a percentage note rather than a real receivable balance.

Who Should NOT Use Rebota (Yet)

A business with no RA-billing structure (single lump-sum contracts, no progress billing) has less need for this specific workflow.

When the Other Option Is Genuinely Better

Dedicated invoicing-only platforms with deeper multi-currency or international billing support may suit businesses whose billing needs extend well beyond Indian RA-billing/retention conventions.

When You Don't Need Software At All

A single small project with one or two bills total can reasonably stay on a spreadsheet.

The Short Version

For contractors doing genuine progress billing with retention, this closes the gap between "what was certified" and "what shows up as a trackable receivable" — a gap most spreadsheet-based billing leaves open.

Professional Practices

Review outstanding retention receivable as a real, standing balance — not a percentage buried in old invoices — so a negotiation for early release or a bank-guarantee substitution is based on an accurate current number.

Common Mistakes

Patterns we see repeatedly across Indian construction sites — worth checking against your own process.
1
Tracking retention only as a bill-header percentage rather than a ledger receivable
Total retention locked up across active projects is invisible until someone manually reconstructs it from old invoices — usually only when cash flow pressure forces the question.
2
Billing from a manually re-assembled summary instead of certified Measurement Book quantities
Discrepancies between what was billed and what was actually measured surface as client disputes later, when they are harder and slower to resolve.

Frequently Asked Questions

How is retention tracked once a bill is raised?
Retention is posted to its own ledger account (Retention Receivable) at the point of billing, so it shows up as a real, trackable balance rather than just a percentage note on the invoice.
Does RA billing require the BOQ module?
Yes — RA bills pull certified quantities from BOQ line items and the Measurement Book, so the two modules work together rather than as separate systems.
