About FaultExpert Mobile Office
FaultExpert Mobile Office is a local-first invoice PWA for field and truck technicians. Build invoices in the truck — fully offline, no account, no monthly fee. Customers pay you directly via Venmo, Zelle, or Cash App. Your books are a file you own. One-time $49, not a subscription. Runs on Android, iPhone, and desktop.
FaultExpert Mobile Office is invoicing software built in the truck, for the truck. It is a local-first PWA for field service and industrial technicians who need to invoice jobs without cell signal, without a SaaS login, and without a monthly bill.
Unlike Jobber, Housecall Pro, or ServiceTitan, this is a one-time $49 purchase. Nothing to cancel, nothing expires. Optional add-ons (AI diagnosis, hosted sync, annual code refresh) are subscriptions you can cancel — the core app keeps working forever.
Features: invoices, quotes, and sales orders
