Final bill checklist: 15 things to close before you sign

The final bill is the last chance to be paid for the work. Once you sign it, and in many contracts sign a declaration that you have no further claims, reopening anything is slow and uncertain. Yet final bills are often prepared in a hurry, months after the last RA bill, by someone who did not work on the site.

This checklist is the set of items we would close before signing. It assumes an item-rate contract billed through running account bills, the common case for CPWD, state PWD, municipal and developer work. Your contract's own conditions come first wherever they differ.

Quantities and items

• 1. Every measurement is recorded and accepted. Items measured jointly at completion, such as final levels, external works and making good, are in the measurement record and signed off by the engineer.
• 2. Cumulative quantities reconcile with the last certified RA bill. The previous column of the final bill equals the up-to-date certified quantity of the last RA bill, item by item. Any held quantity is either claimed with evidence or written off by decision.
• 3. The deviation statement is complete. Every item executed above BOQ quantity has an approval reference. Savings are listed too, because the engineer will look for them.
• 4. Extra and substituted items have approved rates. Any item paid on account at a provisional rate is settled at its approved rate, and the difference appears on the final bill, whether it is in your favour or not.
• 5. Part-rate balances are released. Every item paid at a part rate is either moved to full rate or carries an agreed reduced rate for work accepted as is.

Advances and material

• 6. Mobilisation advance is fully recovered, with interest. Recompute the interest for the whole period, using the contract's method, and compare with what was recovered bill by bill.
• 7. Secured advance is fully adjusted. Every secured advance taken on material brought to site is adjusted against the work in which the material was used. None should remain on the final bill.
• 8. Client-issued material is reconciled. For cement, steel or any other material the client issued, compare quantity issued with theoretical consumption for the work done. Recovery for excess consumption or unreturned material should be computed by you first, at the rate the contract sets.

A worked check on the material reconciliation: if 1,840 bags of cement were issued and the theoretical consumption of the work done is 1,812 bags, the difference is 28 bags. Within the contract's permitted variation it may need no recovery at all; beyond it, recovery applies at the contract's rate. Either way, show the computation yourself and leave nothing for the client's accounts team to work out.

Price, time and penalties

• 9. Price variation is worked out to the end. If the contract has a price variation clause (in CPWD contracts it is commonly known as clause 10CC), compute it for every quarter up to the period the contract allows, with the indices in force for each.
• 10. Extension of time is decided, and any compensation is settled. Make sure every extension of time application has a written decision. Liquidated damages, if any, are an amount decided by the competent authority under the contract: enter what was decided, and keep the order on file.

Retention and taxes

• 11. Retention and security deposit are totalled, with release dates. Add up every amount withheld across all bills. Note the defect liability period end date and the date you can apply for release. Retention is easy to forget once the site is closed; our post on retention money covers tracking it.
• 12. Income-tax TDS matches Form 26AS and AIS. Every amount deducted on every bill should appear in your annual tax statement. Missing credits are easier to chase while the client's accounts team still remembers the work.
• 13. GST TDS credits are accepted on the GST portal. For government clients, check that each bill's GST TDS appears on the portal and has been accepted into your cash ledger.
• 14. The GST invoice for the final bill is right. If the final bill reduces anything already invoiced, issue the credit note the law requires, and keep invoice values matching certified values.

Papers and signature

• 15. Handover papers are complete, and so is the signature step. Completion certificate, as-built drawings, test reports, warranties and guarantees are handed over with an acknowledgement. Then read the final bill and any no-claim declaration line by line before signing. If you are reserving a claim, put it in writing in the way your contract permits, and take legal advice on any amount in dispute.

Why the order matters

The list runs from quantities to money to papers for a reason. Recoveries depend on quantities: the cement reconciliation needs the final quantities of concrete, plaster and masonry. Price variation depends on the value of work done in each quarter. Retention depends on the final gross value. Close the quantities first and the rest follows from them.

A note on time

Final bills slip because each of these items needs a person who knows the history. The billing engineer has moved to a new site; the site engineer has left; the Excel workbook has five versions. The best preparation for a final bill is a clean record kept through the RA bills: a part-rate register, a held-quantity list, an advance recovery schedule and a material reconciliation that is updated every month, not reconstructed at the end.

How Tatha Vastu helps at final bill time

Final bill mode in the RA bill generator closes cumulative quantities, lists open part-rate balances and held quantities, and reconciles advances and issued materials. The recoveries engine shows each advance recovered to date against its schedule, and the retention release schedule is tied to the defect liability end date of each work order.
