The bid contract work was accepted, invoices were issued, but the money has sat with the project owner for a full year. At this point the problem is no longer relationships or verbal reminders: every passing month costs the contractor interest on withheld funds and moves it closer to limitation deadlines that can extinguish the claim. This article systematises how to collect a bid-contract payment debt one year overdue — computing the right amount, following the right sequence, and protecting limitation.
Compute the claim correctly: principal, penalty and interest are three separate heads
Head one is principal: the value of accepted work unpaid under the acceptance minutes and payment periods in the contract. This is a pure payment debt; the file’s strength turns on whether acceptance minutes are fully signed and whether the owner has confirmed the debt reconciliation. Head two is the late-payment penalty, which exists only if the contract contains a penalty clause: the rate follows the parties’ agreement under Article 418 of the 2015 Civil Code, and for commercial contracts Article 301 of the 2005 Commercial Law caps the penalty at 8% of the value of the breached obligation — here, the timely-payment obligation for each period. Head three is interest on the overdue sum: Article 357 of the 2015 Civil Code requires a party late in paying money to pay interest on the overdue amount for the overdue period; where the contract sets no rate, a commercial relationship can use Article 306 of the 2005 Commercial Law — the average market overdue-debt rate at the time of payment. Penalty and interest can be claimed together where the contract agrees a penalty, because they differ in nature: the penalty sanctions breach, the interest prices the use of money.
One frequently under-computed detail: interest and penalty run per payment period, not on the total debt from a single common date. A March acceptance overdue from April has a longer overdue period than a September one; a professional collection schedule always separates each period with its own due date under the contract’s payment clause. After a year, the gap between lump-sum and per-period computation can be large enough to change the owner’s negotiating posture.
Collection sequence: reconcile the debt first, sue second
Step one is a written debt reconciliation: a schedule of each acceptance period, amounts paid, amounts outstanding, and penalty and interest computed to the schedule date, sent to the owner for signed confirmation. An owner-signed reconciliation is an admission of debt with special evidentiary value in court and can, in many cases, restart limitation under the Civil Code rules on acknowledgment of obligations. Step two is a formal demand letter with a final payment deadline, stating that suit will follow claiming all penalty and interest to the actual payment date plus legal costs as prescribed. Step three, for state-funded packages, is the bidding petition and situation-handling channel in Article 131 of Decree 24/2024/ND-CP for payment arrears arising during package performance, with parallel letters to the competent person and the capital-management authority where the owner is a budget-using unit — administrative pressure is surprisingly effective on long payment arrears, because late payment to contractors is itself criticised conduct in public-investment management. Step four is suit in the competent court or arbitration under the contract’s dispute clause, with interim measures if the owner shows signs of dissipating assets.
Limitation: the most dangerous deadline after one year of delay
For commercial disputes, Article 319 of the 2005 Commercial Law sets a 02-year limitation from the date lawful rights and interests were infringed — that is, from each payment period’s due date left unpaid, computed period by period. A debt one year overdue means half the limitation of the oldest period has already run. Two protective acts must happen now: complete a signed debt reconciliation (acknowledgment can restart limitation under the Civil Code), and, if negotiation drags without result, file suit before the oldest period touches the 02-year mark instead of waiting for a global settlement. Note that courts apply limitation only on a party’s request before first-instance judgment, so expiry is not automatic — but no contractor should bet its receivable on the other side forgetting to raise limitation.
Leverage outside court — and what not to do
Beyond litigation, the contractor holds three lawful levers: suspending unperformed work under the contract clause where the contract permits it for late payment (following the notice procedure exactly); retaining documents the contract allows to be retained until payment (only within the contract’s scope, avoiding as-built records that are unconditional handover obligations); and recording the late payment in capability files where the owner enters other relationships — within the limits of truthful information. Prohibited moves include: self-help set-off against the owner’s assets on site, publishing untrue accusations, and above all abandoning ongoing work in a state dangerous to the project. The end goal is collecting money, and every lever must serve that goal rather than converting the creditor into the newest breaching party.
Frequently Asked Questions
What can be claimed on a bid contract unpaid for a year?
Three separate heads: principal — accepted but unpaid value; a late-payment penalty if the contract has a penalty clause, under Article 418 of the 2015 Civil Code with the 8% cap in Article 301 of the 2005 Commercial Law for commercial contracts; and interest on the overdue sum under Article 357 of the Civil Code, or the average market overdue rate under Article 306 of the Commercial Law where no rate was agreed.
How is late-payment interest on a bid contract computed?
Per payment period, from each period’s due date to the actual payment date. The rate follows the contract first; absent agreement, a commercial relationship uses Article 306 of the 2005 Commercial Law — the average market overdue-debt rate at the time of payment. Computing on the total debt from one common date is an error that costs the contractor money.
Can a one-year-overdue contract payment still be sued on, and what is the limitation?
Yes, but act now. Commercial-dispute limitation is 02 years under Article 319 of the 2005 Commercial Law, running from each payment period’s unpaid due date. After one year of delay the oldest period has burned half its limitation; complete a signed debt reconciliation as an admission of debt and file before the oldest period reaches 02 years if negotiation fails.
Where do you press a state owner that pays late?
Start with reconciliation and a formal demand letter as usual. For state-funded packages, add a petition and situation-handling request under Article 131 of Decree 24/2024/ND-CP to the competent person and the capital-management authority; administrative pressure often works on prolonged budget arrears. Failing that, sue in court or arbitration under the contract clause.
