Learn how tracking construction project cost and project cash flow helps catch overspending before it happens.

Construction is an industry where every small thing costs. Taking care of Subcontractor RA Bills is an important yet complex and time-consuming process. Taking time to handle BOQs, tracking of progress, verifying transactions or claims, and making timely payments- it is a whole lot of process, and it is necessary to avoid overspending. When subcontractor RA bills are not tracked within the wider construction project work, costs can escalate unexpectedly and compromise the entire project cash flow. It can be chaotic with your same old boring ways but with Onsite you can bring speed and accuracy to the process. Let’s get to know how.
Why Subcontractor RA Bills Often Go Out of Control?
The main problem is that things aren’t always the same. Site teams measure work based on what really happens on the ground. Subcontractors write up bills using their own notes. The last piece of information that comes to the accounts teams is what they work with. Everyone is working with incomplete knowledge since there is no single point of reference.
As more adjustments come in, approvals start to slow down. Bills are still pending because it’s hard to check older versions. When it comes time to pay, small discrepancies in amounts or rates can turn into fights. When there are a lot of subcontractors on a big project, this misunderstanding quickly messes up cash flow projections.
If there isn’t a systematic approach, RA billing becomes reactive instead of planned.
Understanding RA Bills in Construction Projects

Why Manual RA Bill Processes Break Down?
Construction work is full of surprises every day and you need to be ready all the time. Many changes can take place in a construction project like revision in drawing, evolution of scope, and execution plans. Manual RA bill processes struggle to keep pace with these changes. Manual spreadsheets don’t give you insight into project cost estimation, causing teams to react late when overspending shows up in RA bills.
This leads to many problems like multiple bill versions, incomplete site verification, missing supporting documents, and unclear approval status. There is no documented record for things and there are no updates of changes when things are done manually. The absence of traceable records makes it hard to explain billing decisions, especially when projects close. Without a system that respects project stages, teams often discover overspend only after cash flow is tight.
How a Structured RA Bill Process Should Function
The charging procedure for a reliable RA starts on site, not at the accounts desk. Before a bill is sent out, the work that has been done is measured where it took place and compared to the BOQ items. These checked amounts are what everyone uses as a starting point.
The subcontractor then makes the RA bill utilizing those numbers that have been checked. Project teams check it against the agreed-upon pricing and scope, and any adjustments are clearly stated instead of being handled informally. After the bill is approved, it goes to the accounts department to be paid. There is a record of every version and approval for future reference.
This billing procedure cuts down on disputes and speeds up payment cycles because everyone is working with the same information.
