Payment Terms and Collection Practices

Unpaid invoices represent one of the most common causes of contractor insolvency in the U.S. Virgin Islands. Whether the work involves federal facilities at St. Croix, USVI government infrastructure projects, or private commercial builds, the structure of payment terms determines how quickly a contractor gets paid — and what legal tools are available when payment fails. Understanding both the federal prompt payment framework and local USVI trade statutes is not optional; it is a core business competency.

Federal Prompt Payment Requirements

On federal contracts, the Prompt Payment Act, 31 U.S.C. §§ 3901–3907, sets the baseline. Federal agencies must pay a proper invoice within 30 days of receipt, or within 30 days of acceptance of the work — whichever is later. If payment is not issued within that window, the contractor is entitled to automatic interest without submitting a separate claim.

The interest rate is set by the U.S. Department of the Treasury and adjusted semi-annually. Under FAR Subpart 32.9, the penalty interest begins accruing on day 31. No demand letter is required to trigger the interest obligation — the right is statutory. FAR 32.906 also establishes that if an agency fails to pay within 75 days after receiving a proper invoice, the contractor may request a remedy from the contracting officer.

For construction contracts with a designated payment office, FAR 32.903 identifies specific contract types where different due-date calculations apply, including contracts with progress payment clauses. Contractors working on USVI federal infrastructure — such as Department of Defense or GSA-managed facilities — operate under these exact rules.

Invoice Requirements: What Makes a "Proper Invoice"

A contractor's clock does not start until a proper invoice is received by the designated billing office. Under FAR 32.905, a proper invoice must include at minimum:

• Contractor name and address
• Invoice date and invoice number
• Contract number or other authorization
• Description of goods or services, quantity, and unit price
• Name and address of the designated billing office (if different from the payment office)
• Taxpayer Identification Number (TIN)

A missing TIN or absent contract number is sufficient grounds for a federal agency to return the invoice as defective without triggering the 30-day clock. USVI contractors frequently encounter this defect on first submissions.

USVI Local Payment Obligations

At the territorial level, USVI Title 27 (Trade and Commerce) governs commercial payment obligations between private parties. USVI contract law recognizes the enforceability of net-30, net-45, and retainage provisions. Retainage — typically 10% withheld until substantial completion — is standard on public works in the territory.

Contractors should confirm whether the USVI Department of Public Works or other contracting agencies follow internal prompt payment policies consistent with federal standards. On hybrid federal-territorial projects (such as FEMA-funded disaster recovery work), both frameworks may apply simultaneously, which creates a compliance layer that requires careful invoice segregation by funding source.

Collection Practices When Payment Is Delayed

When payment is overdue, contractors have a defined escalation path. Under 31 CFR Part 901, the federal standards for collection of claims include specific rules on written demand letters, the timeline for administrative resolution, and the debtor's right to dispute. Although 31 CFR Part 901 primarily governs agencies collecting from debtors, it also informs the standard of conduct contractors can expect in federal payment disputes.

A structured collection approach typically follows this sequence:

1. Written demand letter — Sent to the contracting officer and designated billing office citing the specific invoice number, contract number, date, and amount owed. Include a citation to 31 U.S.C. § 3902 for interest accrual.
2. Contracting officer's representative escalation — If no response within 7 business days, escalate in writing to the Contracting Officer (CO) with a formal record of the initial demand.
3. Claim submission under Contract Disputes Act — For federal contracts, a certified claim must be submitted for amounts exceeding $100,000. Claims under $100,000 do not require certification but must be submitted in writing.
4. Interest documentation — Maintain a running calculation of accrued interest under the applicable Treasury rate. This record supports any subsequent dispute resolution or Board of Contract Appeals filing.

On private USVI projects, mechanics lien rights provide the parallel enforcement tool. USVI lien statutes require timely filing tied to the last date of material or labor supply, and the filing deadline must be tracked from project closeout — not invoice date.

Small Business Considerations

The SBA Contracting Guide identifies prompt payment protections as a priority concern for small business contractors, particularly those operating as subcontractors. Under the FAR flow-down requirements, prime contractors receiving federal funds must pay subcontractors within 7 days of receiving payment from the government for work those subcontractors performed. This 7-day rule is a regulatory obligation, not a contractual courtesy.

USVI small contractors functioning as subs on federal projects should include this 7-day flow-down requirement explicitly in their subcontract agreements and reference FAR 52.232-27 as the operative clause.

Recordkeeping as a Collection Foundation

No collection effort succeeds without documentation. Every invoice should be transmitted with a delivery confirmation — email with read receipt, certified mail, or contractor portal acknowledgment. The date of receipt by the billing office is the start of the payment clock. A contractor who cannot prove receipt date cannot accurately calculate interest or meet the threshold for a certified claim.

Maintaining a payment log by contract, including invoice date, receipt confirmation, due date, and amount, converts payment tracking from an informal practice into an auditable business record.
