Michigan market context
What drives demand for Michigan aftermarket shops
Detroit metro's car culture means everything aftermarket-adjacent runs strong: tint, PPF, ceramic coating, wrap, restoration detail. Ann Arbor + the auto-engineering corridor sustain a steady premium market. Salt-belt winters drive paint protection demand.
Michigan film tint laws
Michigan doesn't use a VLT percentage for the windshield or front side windows at all - aftermarket film there is banned outright except a non-reflective strip in the top 4 inches. Rear side windows and the rear window can be any darkness as long as reflectance stays under 35%. Medical exemption available via a physician or optometrist's letter - no state filing or sticker required.
General information, not legal advice. Laws change and enforcement varies; confirm current requirements with the state.
SalesThumb's quote-time VLT check compares proposed shades to the basic MI per-window limits; if the quote becomes an invoice, the customer acknowledges a tint waiver before paying. The check does not model medical, vehicle-class, or paired-window exceptions, so confirm those by hand.

Where are the tint, PPF, and ceramic shops in Michigan?+
They are concentrated in Detroit, Grand Rapids, Warren, and other major metros. Detroit metro's car culture means everything aftermarket-adjacent runs strong: tint, PPF, ceramic coating, wrap, restoration detail. Ann Arbor + the auto-engineering corridor sustain a steady premium market. Salt-belt winters drive paint protection demand.
Does SalesThumb support Michigan state VLT compliance?+
Partly. SalesThumb's quote-time VLT check compares proposed shades to the basic Michigan limits for sedans and SUVs/trucks. It does not model medical, vehicle-class, or paired-window exceptions (for example Colorado's darker rear glass with 70% fronts, Illinois' 50/30 pairing, or multipurpose-vehicle exemptions), so confirm those by hand. If the quote becomes an invoice, the customer acknowledges a tint waiver before paying. An embeddable tint-laws widget for your own website shows Michigan legal limits to customers before they pick.
Can Michigan shops use SalesThumb's mobile app?+
Yes — the Expo-built iOS + Android app is live on the App Store and Google Play, and works anywhere with cell/WiFi, including Michigan. Customer-side login is name + phone + 6-digit SMS code (passwordless); staff-side is email + password with role-based tabs (NONE / INSTALLER / SALES / BOTH per employee). VIN scanner, photo capture, and push notifications are all built in.
Does it integrate with QuickBooks for Michigan shop accounting?+
Yes, on the Growth plan and up — per-shop QuickBooks Online OAuth. Paid invoices push one-way to QuickBooks and the matching customer is created automatically. Michigan shops on QBO connect once, then push paid invoices with a click. (Two-way sync is on the roadmap.)
