Who uses invoice factoring in Wyoming?

Wyoming receivables come mostly from energy and minerals. Coal mines in the Powder River Basin around Gillette, oil and gas operators, and trona (soda ash) mines in Sweetwater County near Green River buy trucking, equipment, repair, fabrication and oilfield services. Uranium and bentonite add smaller supply chains. In Cheyenne, F.E. Warren Air Force Base, home of the 90th Missile Wing and its Minuteman III fields, contracts for construction and support work. Tourism around Yellowstone, Grand Teton and Jackson supports hotels, food suppliers and contractors, and cattle ranching drives agricultural receivables.

Energy work is cyclical: drilling and mine activity rise and fall with commodity prices, and service companies can see customers stretch payment in a downturn. Oil and gas contractors have a separate lien under Wyo. Stat. §29-3-101 et seq. that can attach to wells, mines and pipelines. Public payers must pay within 45 days or owe 1.5% a month, and tourism businesses that sell to hotels and parks run on a short summer season.

Industries that factor most: Coal mining, Oil and natural gas production and oilfield services, Trona and soda ash mining, Tourism and hospitality, Cattle ranching and agriculture.
Metro areas: Cheyenne, Casper, Gillette, Laramie, Rock Springs.
Federal installations that buy from local firms: F.E. Warren Air Force Base (Cheyenne).

Does Wyoming regulate invoice factoring?

Wyoming has no commercial financing disclosure law, so a factor is not required by state law to give you a standardized cost disclosure. There is no federal one for business financing either. That puts the burden on you to get every fee in writing.

Factoring is generally structured as a purchase of your invoices rather than a loan, which is why consumer lending rules and usury caps generally do not apply to it. The protections that do apply come from your contract and from the Uniform Commercial Code, which governs the sale of accounts in every state.

Ask any provider for the total dollar cost on a sample invoice, the advance rate, every fee, the term and the exit terms. Our proposal checklist lists what a good proposal shows, and the disclosure law tracker shows which states require it.

How do UCC filings work in Wyoming?

Where UCC-1s are filed in Wyoming: Wyoming Secretary of State, Business Division (UCC and EFS filings). The online UCC E-System requires a registered account with prepaid fees; the same office also runs the central filing system (EFS) for farm product liens.

A factor will search that index on your exact legal name before it funds, and will file its own UCC-1 on your accounts receivable at closing. Anyone already claiming your receivables, such as a bank, an SBA lender or a merchant cash advance provider, must release, subordinate or sign an intercreditor agreement first. Search your own name first at the official Wyoming UCC search; old filings from paid-off lenders are common and can take a week or more to terminate. More in UCC liens and intercreditor agreements.

How fast do government payers in Wyoming pay?

Wyoming state agency deadline (Wyo. Stat. §16-6-601 and §16-6-602): 45 days after receipt of a correct notice of the amount due, unless the contract says otherwise. Late interest: 1.5% a month on the unpaid balance from the 45th day until paid, unless there is a good-faith dispute. Applies to any state agency or political subdivision buying goods or services, including construction services, from a nongovernmental entity. There is no statutory deadline for a prime contractor to pay its subs on public jobs.

Federal agencies follow the Prompt Payment Act: generally 30 days after a proper invoice, with interest at the Treasury rate (4.75% for July 1, 2026 to December 31, 2026) when they pay late. To factor federal invoices, the funder usually needs an assignment of claims acknowledged by the contracting officer, which adds a week or two to setup. See factoring for government contractors and the prompt payment interest calculator.

What do Wyoming lien and prompt pay rules mean for construction factoring?

Funders that factor construction receivables check lien and bond rights before they advance on a pay application, because those rights are what get an unpaid sub paid. Described generally:

Mechanics lien deadline (private work, Wyo. Stat. §29-1-201 et seq. and §29-2-101 et seq.): Subcontractors and suppliers generally have 120 days (prime contractors 150 days) after the earlier of last furnishing or substantial completion (§29-2-106); a notice of intent must go to the record owner at least 20 days before filing (§29-2-107). To enforce: Suit within 180 days after the lien statement is filed (§29-2-109).
Preliminary notice: Required. Subcontractors and suppliers must send notice to the record owner within 30 days after first furnishing, with a copy to the contractor they work for; prime contractors must send it before receiving any payment. Missing it bars the lien (§29-2-112).
Private prompt pay: we could not verify a general private construction prompt payment law in Wyoming; your subcontract's pay terms control.
Public projects (Wyo. Stat. §16-6-112 to §16-6-121): you cannot lien public property, so payment bonds take its place. Bond required: Public works contracts over $150,000 require a bond of at least 100% of the contract price; at $150,000 or less the public entity may accept another approved guarantee. Claim notice: Subcontractors and suppliers must notify the general contractor of their right to bond protection within 60 days after first furnishing (§16-6-121); suit within 1 year after final completion of the public work (§16-6-115).
Read every lien waiver before you sign it, and ask counsel how a waiver signed before payment affects your rights. More in factoring for construction subcontractors.

What else should a Wyoming business know?

Wyoming's 1.5% a month interest on late public payments (§16-6-602) covers goods and services generally, not just construction.
Oil, gas, mine and pipeline work has its own lien under §29-3-101 et seq., filed with the county clerk generally within 180 days after last furnishing, for amounts over $750.
Wyoming's 30-day preliminary notice for construction liens is short, and missing it bars the lien, which matters to a factor buying a subcontractor's invoices.

Questions people ask

Is invoice factoring legal in Wyoming?

Yes. Factoring is a sale of accounts receivable, and Wyoming handles it under its version of UCC Article 9. The factor usually files a UCC-1 with the Secretary of State to perfect its interest. Wyoming has no state license or registration specific to commercial factoring, so the contract terms (recourse, reserve and fees) carry most of the weight.

Does Wyoming require a disclosure for factoring deals?

No. As of November 2026, Wyoming has not passed a commercial financing disclosure law, so a factor does not have to give you a state form showing an APR or total cost. Ask for every fee in writing and compare offers on the effective cost per month, including minimums and termination fees.

Where do I search for UCC liens in Wyoming?

The Wyoming Secretary of State keeps UCC records in its online UCC E-System at ucc.wyo.gov. Searching online requires a registered account with prepaid fees, and written search requests can also be sent to the office. Search your own business before you factor, since a lender's existing lien on receivables can block a new factor.

Do Wyoming government agencies pay interest on late invoices?

Yes. Under Wyo. Stat. §16-6-602, a state agency or local government that buys goods or services must pay within 45 days of a correct invoice, unless the contract says otherwise. After that it owes 1.5% a month on the unpaid balance, unless the amount is in good-faith dispute. That rule makes Wyoming public receivables dependable collateral for factoring.

How fast can a Wyoming business get funded by factoring?

With a clean file (current AR aging, invoices, a clear UCC search and creditworthy customers), first funding commonly takes about one to three weeks, and later invoices usually fund within a day or two of verification. Federal receivables take longer because of the assignment of claims.
