—Overview
Cereezer is a field service management platform for companies that work at their customers' premises: customers, sites, assets, contracts, dispatching, work orders, signed reports and operational invoicing in a single tool. Symfony 7.4 and API Platform run the backoffice, Mercure keeps every screen live, and an offline-first Ionic app carries the job to the field — so a completed visit becomes a signed PDF report and an invoice line without a second data entry.
02The front
What people see.
Planning, field app, asset registry, quotes and invoicing, van stock and indicators read and write the same job file. Nothing is copied from one screen to the next, and nothing has to be reconciled at the end of the month.
From the first call
to the invoice
Every asset carries its own history, its regulatory deadlines and its defects, so a recurring contract schedules its own visits. What the technician checks, photographs and gets signed on site comes back as billable lines — even when the van spent the day out of network.
Complete a job in under 60 seconds — open, start, check, photo, sign, done. Everything else is automatic.
