Stokpax vs ARI

An honest Stokpax vs ARI comparison: ARI is repair-shop software from $33.33/month with a 5-invoice trial cap, not a parts-store inventory tool.

ARI (also sold as ARI Auto Repair Software) is a mobile-first repair-shop app — VIN decoder, license-plate scanner, vehicle service history, automated reminders, digital inspections and online appointment booking, with spare-parts inventory and invoicing built in to support that workflow. It bundles a lot into two flat-priced plans with unlimited users, which is genuinely competitive for a solo or small shop. The catch: its inventory exists to support a job card, not a standalone counter or wholesale parts sale, and its "free trial" isn't measured in days — it's capped at 5 invoices, estimates, inspections, clients and vehicles combined. Stokpax is the other shape — inventory, invoicing, customer/supplier accounts and cash for a business that sells stock, with a full 7-day trial and no repair-order workflow to work around. Here is a straight comparison, including where ARI is the better fit.

The honest verdict

If you run a repair shop and want VIN decoding, license-plate lookup, digital inspections and online appointment booking in one mobile-first app with unlimited users, ARI is a well-priced, dedicated choice from $33.33/month billed annually. But if you are a parts store or wholesaler with no repair orders to track — just stock coming in and invoices going out — its job-card-first billing and a free trial capped at 5 invoices rather than days make it a mismatch. Stokpax covers inventory and invoicing natively for that business, from $29/month with a full 7-day free trial.
