Municipal Vendor & Contractor Payment Disputes - Denver

In Denver, Colorado, contractors and vendors who have a payment dispute with the City and County of Denver should follow the city's procurement and contract claims process administered by Procurement Services^[1]. This guide explains typical scenarios, immediate actions, required documents, administrative steps, and appeal routes to pursue a payment claim against municipal contracts.

Scope & When to Use This Process

This process covers disputes where a vendor or contractor asserts unpaid invoices, disputed change orders, or contract payment withholding by the City and County of Denver under municipal procurement or contract terms. Use this process when the payment arises from a city contract, purchase order, or awarded solicitation and when informal resolution with the project manager fails.

• Invoices unpaid after the city’s stated payment terms.
• Disputed change orders or claims for extra work.
• Withholding or set-off of payments due to alleged noncompliance or defects.
• Administrative denials that cannot be resolved with the contracting officer.

Penalties & Enforcement

Denver’s procurement practice focuses on contract remedies and administrative actions rather than preset statutory fines for vendor payment disputes. Specific fine amounts and per-day penalties are not specified on the cited page.^[1]

• Fine amounts: not specified on the cited page.
• Escalation (first/repeat/continuing offences): not specified on the cited page.
• Non-monetary sanctions: common municipal remedies include withholding payments, contract suspension or termination, administrative debarment or suspension from future awards, and referral to the City Attorney for collection or set-off.
• Enforcer: Procurement Services administers contract disputes and remedies; the Office of the City Attorney may handle litigation or collection if referred.
• Inspection and complaint pathways: start with the contracting officer and Procurement Services; unresolved claims may be escalated administratively or to the City Attorney.
• Appeal and review routes: the cited Procurement Services page references protest and claims processes but does not state specific time limits; parties should file written protests or claims promptly with Procurement Services and follow published instructions.^[1]
• Defences and discretion: common defences include lack of contractual entitlement, defective work, or failure to comply with notice or billing procedures; the city may exercise discretion via waivers, change orders, or negotiated settlements.

Applications & Forms

The Procurement Services site is the primary starting point for forms and instructions for protests or contract claims; a specific universal "vendor protest form" or standardized claim form is not specified on the cited page, so parties must follow the procedures and submission contacts listed by Procurement Services.^[1]

Practical Action Steps

• Gather all contract documents, purchase orders, change orders, approved submittals, pay applications, lien waivers, and correspondence.
• Submit a written claim or protest to the contracting officer and Procurement Services promptly, following any contact instructions on Procurement Services resources.
• Track deadlines in the contract for notice of claims and preserve proof of service for any notices delivered.
• If administrative steps fail, request review or appeal as permitted in the contract; consider referral to the City Attorney for collection or pursuing an action in court where municipal immunity does not bar the claim.

FAQ
