Shop owners who actually use Tendwa
Real owners, real Saturdays, real bays. Here’s what they’ve told us.
“Saturdays used to mean a stack of paper tickets to enter on Monday. Now an estimate goes to invoice in a few clicks and the customer signs on the screen before they leave the lot. Our books close themselves.”
Ramendra Sharma
Manager, Big Tire & Wheels · Sacramento, CA
“The plate and VIN decoder is the killer feature. We type a plate, get the year, make, model, and tire fitment in a second. It saves five minutes on every walk-in — that adds up fast.”
Ismail
Owner, Tire & Wheel Xpert · Hayward, CA
“Tracking tire and wheel inventory used to be guesswork. Tendwa shows me exactly what's selling and what's sitting, and the dashboard tells me where my margin is going. I order smarter every month.”

Owner, Yuba Tire & Wheels · Yuba City, CA

What exactly is Tendwa?
Tendwa is an all-in-one operating system for tire and wheel shops — POS, tire & wheel inventory, estimates with digital approval, full VIN decoding, customer & vehicle records, and dashboard reporting in one platform. Replaces the patchwork of spreadsheets, paper tickets, and a generic POS.
Who is Tendwa for?
Independent tire and wheel shops, multi-location groups, and automotive service centers that have outgrown a generic POS. Trusted today by shops across California — from Sacramento and Yuba City to the Bay Area and the Central Valley.
How is Tendwa different from a generic POS?
Generic POS systems treat every line item the same. Tendwa knows tires (size, speed and load rating, fitment), wheels (offset, bolt pattern, hub bore), and vehicles (VIN, plate, service history). Searches, reports, and the checkout flow are all built around how a tire shop actually works.
Can Tendwa handle tire AND wheel inventory?
Yes — wheels are a first-class module, not buried under generic parts. Track maker, style, offset, bolt pattern, and hub bore separately from tires. Drop either onto an invoice in one click.
Does Tendwa support estimates and digital approvals?
Yes. Build a branded estimate, send the customer a single link, and they sign on screen and approve — no app or login needed. The approved estimate converts to an invoice in one click, with the signature timestamped for your records.
What about VIN decoding and license plate lookup?
Tendwa decodes 17-character VINs to make/model/year/engine specs/oil specs/tire & wheel fitment. License plate decoder works for US plates. Both save about five minutes per walk-in.
Is my data secure?
Yes. Encryption in transit (TLS) and at rest, role-based access with audit logs, daily encrypted backups, JWT-based API auth, and strict company-level data isolation. Full details in our Security Policy.
How long does setup take?
Most shops are live in under a week. We import your existing inventory from CSV or your old POS, configure roles for your team, and walk through your first ticket together.
