Running Account billing is where construction money actually moves, and where errors cost the most. The BuildX RA Billing module automates the entire cycle: bill against measured quantities certified to the contract BOQ or schedule of rates, apply retention and advance recovery, handle statutory deductions, and reconcile each bill against the contract — for both incoming client bills and outgoing subcontractor bills. Every cycle is correct, certified and fully traceable.
This module is part of the integrated BuildX platform — so it shares one source of truth with cost, billing, procurement and site data, and is built and supported by a certified Frappe partner with a large in-house team.
