Running Account billing is the financial heartbeat of construction — and the place errors cost the most. BuildX automates measurement-based RA bills with retention, recovery and statutory deductions, for both client and subcontractor billing.

RA billing is where construction money actually moves — and where mistakes are most expensive. A wrong measurement, a missed retention, an unrecovered advance or a deduction applied incorrectly, repeated across cycles and contractors, quietly drains margin and creates disputes that sour client and contractor relationships.
Running Account billing should be precise, fast and consistent — yet it is often done in spreadsheets, where measurements, retention, recovery and deductions are easy to get wrong. BuildX automates the entire RA cycle: bill against measured quantities, apply retention and advance recovery, handle statutory deductions, and reconcile each bill against the contract — for both client billing and subcontractor bills. Every cycle is correct, certified and fully traceable.
BuildX is built and supported by a certified Frappe partner with a large in-house team — so this is solved with a real platform, not a spreadsheet or a workaround.
Bill against measured quantities of executed work, certified and traceable to the contract BOQ or schedule of rates.
Apply retention each cycle and release it against milestones automatically — no missed or mis-timed retention.
Recover mobilisation and material advances against running bills on schedule, so advances do not become bad debt.
Apply TDS, GST and other statutory deductions correctly and consistently on every bill.
Run both incoming client RA bills and outgoing subcontractor RA bills through the same controlled, reconciled flow.
A complete RA-bill register per contract, reconciled against contract value, retention held and amounts certified.
BuildX RA billing is configured by a team that knows construction billing practice — measurement, retention, recovery and deductions handled the way contracts actually require. As a certified Frappe partner with a large in-house team, Quantbit brings experience across platform development, implementation and end-to-end solutions for many industries — so your project benefits from proven architecture and patterns from day one.
BuildX bills against measured quantities of executed work, certified and traceable to the contract BOQ or schedule of rates — so every RA bill reflects exactly what was done, with no over- or under-billing.
Retention is held each cycle and released against milestones, and mobilisation and material advances are recovered on schedule — automatically, so the errors that drain margin in manual billing simply do not happen.
Incoming client RA bills and outgoing subcontractor RA bills run through the same controlled, reconciled flow with a complete bill register per contract — giving full visibility of what is billed, held and certified on both sides.
Concise, factual answers — written to be accurate and easy to reference, whether you are reading or researching through an AI assistant.
