Michigan invoice collection law: what small businesses need to know
Michigan's recording-consent law is genuinely contested in the case law. Michigan extends FDCPA-style protections to first-party creditors under MCL 445.251, and the MCPA covers unfair-practice exposure on top of the federal TCPA floor.

Michigan's recording-consent law under MCL 750.539c is contested. Federal courts have read it as one-party for participants; Michigan's Supreme Court has not definitively ruled. Syntharra discloses recording on every Michigan call, satisfying any two-party-style interpretation.
Federal TCPA: 8 AM to 9 PM in the consumer's local timezone. Syntharra calls Michigan customers between 9 AM and 8 PM, weekdays only.
Michigan Regulation of Collection Practices Act + MCPA + federal TCPA
Michigan has the most contested recording-consent law of any major state. MCL 750.539c has been read by federal courts in the 6th Circuit (Sullivan v. Gray) as one-party for participants, but the Michigan Supreme Court has not definitively addressed the question. Conservative practice treats Michigan as effectively two-party until that ruling lands. The Michigan Regulation of Collection Practices Act (MCL 445.251 et seq.) is also unusual: it extends FDCPA-style restrictions to first-party creditors, putting Michigan in the same camp as Pennsylvania, Florida, and California for in-house AR work. The Michigan Consumer Protection Act (MCPA, MCL 445.901 et seq.) gives consumers a private right of action on unfair-practice claims. Federal TCPA still governs every automated call. Syntharra discloses the recording on every Michigan call, which satisfies any reading of MCL 750.539c.
What you actually need to know
Federal vs Michigan — what changes
The Michigan Regulation of Collection Practices Act extends most FDCPA-style restrictions to creditors collecting their own debts, similar to Florida's FCCPA, California's Rosenthal Act, or Pennsylvania's FCEUA. The act prohibits harassment, false or misleading representations, and unfair practices, and applies regardless of whether the caller is the original creditor or a third-party agency. Federal TCPA continues to govern the AI-voice disclosure and call-window requirements on top of the state-level floor.
Recording consent in Michigan — the contested question
Michigan's eavesdropping statute under MCL 750.539c has been litigated repeatedly without a definitive Michigan Supreme Court ruling on whether participant recording requires consent of all parties. Federal courts in the 6th Circuit (Sullivan v. Gray, 1982) read the statute as one-party for participants. Conservative legal commentary still recommends two-party-style disclosure given the lingering uncertainty. The Syntharra opener — 'This call may be recorded' delivered before any business content — satisfies any reading of the statute, including the strictest two-party interpretation.
MCRPA exposure for first-party creditors
MCL 445.251 prohibits the same broad categories of conduct the federal FDCPA does, and the act applies to creditors collecting their own debts. Combined with the MCPA's unfair-practice provisions, Michigan is a higher-risk state for collections process error than most. Syntharra's hardcoded AI disclosure, three-attempt cap, and immediate dispute routing keep the calls inside the MCRPA's safe lane no matter how the recording-consent question is eventually resolved.
Statute of limitations in Michigan
Michigan gives 6 years to sue on a written contract under MCL 600.5807. District court small-claims jurisdiction is up to $7,000, which is mid-pack nationally for small-claims caps. The 6-year contract limit is also mid-pack and gives meaningful runway for early-cycle voice-agent recovery before any litigation question arises.
Frequently asked questions
Is AI invoice collection legal in Michigan?
Yes, when run inside the federal TCPA + MCRPA framework. AI disclosure on the opener, recording disclosure in the same line (covering both one-party and two-party readings of MCL 750.539c), the 9 AM to 8 PM call window, opt-out honoring, and the three-attempt cap satisfy both Michigan and federal requirements.
Is Michigan one-party or two-party consent for call recording?
Genuinely contested. Federal courts have read Michigan's eavesdropping statute as one-party for participants, but the Michigan Supreme Court has not definitively ruled on the question. Conservative legal practice treats Michigan as effectively two-party. Syntharra discloses the recording on every call, which satisfies any reading of the statute.
Does the Michigan Regulation of Collection Practices Act apply to first-party creditors?
Yes. The MCRPA is one of the state-level statutes that closes the gap between the federal FDCPA's third-party-only coverage and first-party invoice follow-up. A Michigan business calling about its own unpaid invoice is subject to the same anti-harassment and accurate-identification rules a third-party agency would be.
Are Michigan late fees enforceable on commercial invoices?
Yes, when included in the original written contract and reasonable in amount. Michigan law allows commercial late fees in the standard 1.5% per month range; usury caps under MCL 438.31 apply primarily to certain consumer loans rather than commercial AR.
