RA Bill Format for Construction: Running Account Bill Explained

RA bills often cause disputes because site work, measurements and billing records do not match. The contractor may claim one quantity, while the client or consultant certifies another. Previous bill quantities may be copied wrongly. Deductions may appear without explanation. A clear RA bill format reduces these problems and gives every party the same calculation trail.

RA means Running Account. The bill records the value of work completed up to a particular date. It also separates work already billed from work claimed in the current period. The format must remain linked to the approved BOQ, measurement book and previous certified bill.

What is an RA bill?

An RA bill is a periodic claim for payment during a construction project. A contractor may submit it monthly, at a milestone, or after completing an agreed quantity of work. The billing cycle depends on the contract.

The RA bill normally starts with the approved BOQ. For each BOQ item, it shows the total quantity completed up to the bill date. It then deducts the quantity or amount included in earlier bills. The balance becomes the claim for the present bill.

An RA bill is not the final bill. A running bill is provisional and covers work completed during the project. Measurements can be checked, corrected or certified according to the contract. The final bill is prepared after completion and includes the final quantities, approved variations, recoveries, pending deductions and settlement of the account.

The bill should clearly mention the project name, contractor name, client name, agreement or work order number, RA bill number, bill period and submission date. Keep a consistent numbering system such as RA-01, RA-02 and RA-03. Do not restart the sequence when a site engineer or billing person changes.

The RA bill format, column by column

The main RA bill statement should follow the BOQ item order. Avoid changing descriptions or units only to make the bill shorter. The following structure works for many building and interior contracts.

Add separate references for measurement book pages, drawings or variation approvals where useful. If an item exceeds the BOQ quantity, do not hide the excess inside another item. Show it clearly and attach the required approval. A practical BOQ Excel guide can help when the project is still managed through spreadsheets.

How to calculate the amount payable

The basic calculation is simple. First calculate the cumulative quantity. Multiply it by the approved rate. Then subtract the amount included in previous bills.

Example only: Assume the bill contains the following three items. These figures are for explanation and are not standard rates.

The cumulative work value is Rs 222,000. The previous amount is Rs 145,000. Therefore, the gross value of work in this RA bill is Rs 77,000.

Suppose the example bill then shows retention of Rs 3,850, advance recovery of Rs 5,000, material recovery of Rs 2,000 and TDS of Rs 770. Total deductions are Rs 11,620. The example net payable is Rs 65,380, before considering any other applicable tax or contractual adjustment.

Keep the gross work value, taxes, deductions and net payable on separate lines. Do not mix GST with retention or recovery. GST and TDS treatment can depend on the contract, invoice and applicable law. Confirm the calculation with your CA or tax adviser.

Deductions to show in an RA bill

Every deduction should have a clear name, basis and cumulative record. A single line called “other deduction” invites questions and delays.

• TDS: Show the taxable base, applicable treatment and deducted amount. The correct rate and base depend on the law and transaction. Check with your CA.
• Retention: Show current retention and total retention held to date. The percentage, limit and release terms must follow the contract.
• Advance recovery: If mobilisation or another advance was paid, show the opening advance, current recovery and balance.
• Material issued by the client: Record cement, steel or other material issued for recovery. Attach the issue challan and agreed valuation basis.

Other possible adjustments include water or electricity recovery, plant hire, approved debit notes and statutory deductions. Include them only when supported by the contract or a documented approval. Rates depend on the contract and the law, so ask your CA and review the signed work order.

Mistakes that delay payment

• Using item descriptions that do not match the approved BOQ.
• Changing the unit between the BOQ, measurement book and RA bill.
• Claiming quantities without measurement sheets or site approval.
• Using the submitted amount from the last bill instead of the certified amount.
• Repeating a previous quantity because the last RA bill was not locked.
• Including extra work without a variation order or written approval.
• Showing lump-sum deductions without a calculation or supporting challan.
• Forgetting signatures, bill dates, work order references or measurement book page numbers.
• Sending multiple Excel versions with unclear file names.

A useful check is to compare four records before submission: the BOQ, measurement book, previous certified RA bill and current bill. The billing engineer should also confirm quantities with the site engineer or mistri responsible for the work. Mark disputed quantities separately instead of delaying the complete bill.

Keeping RA bills linked to the BOQ and measurement book in an app

Excel does the calculation well when the format is controlled and one person maintains the file. It is familiar, flexible and easy to share. It becomes harder when several sites send different sheets, previous versions remain in WhatsApp groups, or measurement changes are not carried into the bill.

A BOQ software can keep BOQ items, rates and quantities in a structured record. The main benefit is traceability. A billing engineer can compare the approved quantity, measured quantity, previous quantity and current claim without rebuilding the history each month.

Trackovo includes a measurement book along with material, labour, expense, task and daily progress records. It can help a team keep site measurements and project records in one app on Android, iPhone and web. The team also helps import data from Excel and exports your data on request.

This does not remove the need for measurement approval or contract checks. The client, consultant and contractor still need to agree on quantities, rates and deductions. If your present Excel system is disciplined and the project is small, it may be enough. For several projects or several billing users, a structured system can reduce version confusion.

Common questions

What is the full form of RA bill?

RA bill means Running Account bill. It is a periodic claim for the value of work completed up to a stated date, less the value already included in previous bills.

Can I prepare an RA bill in Excel?

Yes. Excel is suitable for many contractors when the BOQ, formulas and previous certified quantities are controlled. Protect formula cells, use clear version names and keep the signed or certified bill separately from working files.

Is an RA bill the same as a final bill?

No. An RA bill is raised during the project and carries cumulative quantities forward. The final bill closes the account after final measurements, variations, recoveries, retention treatment and other contract adjustments are settled.

Which quantity should be carried into the next RA bill?

Carry forward the quantity certified in the previous bill, not merely the quantity that the contractor submitted. If part of a claim was rejected or kept pending, show that difference clearly and claim it again only with the required measurement or approval.
