Work order app: what it looks like and what it costs

A work order app is a system where the office opens a job, assigns it to a technician or crew, and they see it on their phone, log the work, materials and time, and attach photos and the client’s signature. The office always sees what is open, and a closed job can be invoiced right away. For a company with a few field staff, a custom app like this usually costs up to €5,000 and is ready in two to four weeks.

Who needs one?

HVAC and appliance service companies, installers, building maintenance, internet and telecom operators, cleaning services and anyone with people working in the field. The sign you need one: jobs are on paper or in a WhatsApp group, and at the end of the month someone spends hours working out what was done and what to bill.

What it should include

• Job creation from a client request, with address, fault description and priority.
• Scheduling: who goes where and when, by day and by technician.
• A mobile view for the field: the job, directions, work and materials, photos, signature.
• Statuses: open, in progress, waiting for parts, closed, invoiced.
• Link to billing: a closed job becomes an invoice line, with tax reporting and e-invoicing.
• History per client and device: what was done, when and by whom.

Off-the-shelf or custom?

Field service products exist and work well if your business looks like most. The problem starts when jobs must follow your specific logic: special price lists, maintenance contracts, warranties, your own statuses, or links to your existing CRM and accounting. Then you pay per user for a tool that covers half the work, and the rest still lives in spreadsheets. We compare the two in detail in custom software or off-the-shelf tools.

What does it cost?

A simple work order app for one company and one process costs up to €5,000 with us. If you also need a CRM, contracts, a parts inventory or a client portal, it becomes a business system in the €5,000 to €20,000 range. See how much custom software costs for the full breakdown.

How to start without big risk

We first build a working prototype on your real example: the job, the technician view and closing the job. It is ready in five working days and costs €1,000, which is credited if you go ahead with the full build.
