Who uses invoice factoring in Wisconsin?

Wisconsin is a manufacturing state, and most factored invoices come from suppliers to large industrial buyers. Defense is a major payer base: Oshkosh Corporation builds military trucks in Oshkosh, and Fincantieri Marinette Marine builds Navy ships in Marinette, each with a long chain of machine shops, fabricators and logistics firms waiting on payment. Paper, food processing and dairy plants buy packaging, trucking and maintenance on account. Milwaukee has heavy equipment and machinery makers, and hospital systems across the state buy staffing and services. Fort McCoy, the only Army installation in Wisconsin, contracts for construction and support work.

Public payers are governed by strict rules. State agencies (Wis. Stat. §16.528) and local governments (§66.0135) must pay within 30 days of a proper invoice, and a prime contractor paid by a public body must pay its subcontractors within 7 days. Private construction has no prompt pay statute, but money an owner pays a prime or sub is held in trust for unpaid subs and suppliers. That trust rule is worth knowing if you factor a contractor's invoices.

Industries that factor most: Industrial machinery and equipment manufacturing, Defense vehicles and shipbuilding, Food processing and dairy, Paper and packaging, Healthcare services.
Metro areas: Milwaukee, Madison, Green Bay, Appleton, Oshkosh.
Federal installations that buy from local firms: Fort McCoy.

Does Wisconsin regulate invoice factoring?

Wisconsin 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 Wisconsin?

Where UCC-1s are filed in Wisconsin: Wisconsin Department of Financial Institutions (DFI), Division of Corporate and Consumer Services, UCC section. Filing is with DFI, not the Secretary of State; a free search by debtor name or file number is available, and paid UCC-11 searches return certified listings and copies.

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 Wisconsin 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 Wisconsin pay?

Wisconsin state agency deadline (Wis. Stat. §16.528 (state agencies); Wis. Stat. §66.0135 (local governments)): 30 days after receipt of a properly completed invoice, or after receipt and acceptance of the goods or services, whichever is later. Late interest: Interest from the 31st day at the rate in Wis. Stat. §71.82(1)(a), which is 12% a year, compounded monthly. A prime contractor must pay subcontractors within 7 days after it is paid by the agency, or owe interest at the same rate from the 8th day (§16.528(2m)). Exceptions include federally funded payments, good-faith disputes noticed in time, and contracts that set their own late-payment terms. A court awards reasonable attorney fees to the prevailing party in an action for interest.

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 Wisconsin 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, Wis. Stat. §779.01 et seq.): Within 6 months after the claimant last furnished labor or materials, and at least 30 days after serving a notice of intent to file a lien claim on the owner (§779.06). To enforce: Suit within 2 years after the lien claim is filed (§779.06(1)).
Preliminary notice: Subcontractors and suppliers must serve written notice on the owner within 60 days after first furnishing labor or materials (§779.02(2)(b)); prime contractors put the notice in the owner contract or serve it within 10 days of first furnishing.
Private prompt pay: we could not verify a general private construction prompt payment law in Wisconsin; your subcontract's pay terms control.
Public projects (Wis. Stat. §779.14): you cannot lien public property, so payment bonds take its place. Bond required: State contracts over $369,000 require a payment and performance bond ($148,000 to $369,000 unless a substitute assurance is allowed); local government contracts over $148,000 require one ($74,000 to $148,000 unless a substitute is allowed); figures as shown in the current statute. Claim notice: Written notice to the prime contractor within 60 days after first furnishing labor or materials, unless the claimant is listed in the required subcontractor list or the contract is $5,000 or less; suit within 1 year after work under the contract is completed.
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 Wisconsin business know?

UCC records sit with the Department of Financial Institutions, so a lien search on a Wisconsin business starts at DFI, not the Secretary of State.
Construction money paid to a prime or sub is a trust fund for unpaid subs and suppliers under §779.02(5), so a factor buying a contractor's receivables should confirm that lower-tier parties are being paid.

Questions people ask

Is invoice factoring legal in Wisconsin?

Yes. Factoring is a sale of accounts receivable, and Wisconsin handles it under its version of UCC Article 9. The factor typically files a UCC-1 with the Department of Financial Institutions to perfect its interest. Wisconsin has no license or registration specific to commercial factoring. Read the recourse terms, reserve and fee schedule before you sign.

Does Wisconsin require a disclosure for factoring deals?

No. As of November 2026, Wisconsin has not enacted a commercial financing disclosure law, so a factor is not required to give you a state form with an APR or total cost. Ask for every fee in writing (discount rate, reserve, minimums, termination) and compare offers on the effective cost per month.

Where do I search for UCC liens in Wisconsin?

Search through the Department of Financial Institutions, not the Secretary of State. DFI's online system offers a free search by debtor name or file number, and paid UCC-11 searches return certified results with copies. Search your own business before you factor, since an existing bank lien on receivables usually has to be released or subordinated.

How fast do Wisconsin state and local agencies have to pay?

Generally within 30 days of a properly completed invoice or acceptance of the work, whichever is later. After that, interest runs at 12% a year, compounded monthly, unless an exception applies, such as federally funded payments or a timely noticed dispute. Prime contractors must pay subs within 7 days of being paid, so public receivables in Wisconsin tend to be reliable for factoring.

How fast can a Wisconsin 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.
