Estimate the budget for your field service app – from order management and time tracking to offline mode and ERP integration.
In brief
The investment range for a field service app is EUR 13,090 – 133,395 excl. VAT. Jobs, offline use and dispatch sit inside that span.
The calculation follows six visible stages. All figures remain planning values until scope and assumptions have been reviewed.
1. Capture inputs
The calculator records the visible project, volume, complexity and operating parameters selected on this page.
2. Add fixed components
Fixed base modules and selected add-ons are added without mixing them with recurring charges.
3. Apply multipliers
Quantity, complexity and scope factors multiply only the cost components identified for them in the calculator model.
4. Create the range
The calculator applies its documented lower and upper uncertainty factors to the base result; ROI views keep investment and savings visible separately.
5. Round and calibrate
Monetary result fields are rounded to the nearest whole euro. Public project-cost components are calibrated with the centrally maintained display factor.
6. Classify the result
The result is shown as non-binding guidance. A binding quote requires scope, data, integrations, risks and acceptance criteria to be reviewed.
Efficiency or discount factor: A central display factor of 0.7 is applied to public project-cost components to keep all calculators aligned with the currently reviewed pricing basis. It is not a customer-specific discount; customer-entered wages, revenues and existing operating costs are not reduced.
Why this is not a binding quote: The calculator cannot verify complete requirements, third-party dependencies, data quality, legal constraints or acceptance criteria.

FAQ
A field service app with work order management and mobile time tracking starts at EUR 13,090 – 133,395 excl.
VAT. Complete solutions with offline mode, digital forms and ERP integration run that same investment range. The calculator narrows the range by team size, scope and offline capability.
Technicians work in basements, halls and rural areas without a stable connection.
A robust offline mode needs local data storage, synchronisation logic and conflict handling – roughly 35% extra effort that almost always pays off for field teams.
Standard solutions fit when your processes match the market standard – but cost per user per month, forever.
A custom app pays off with special workflows, an existing ERP and more than about 10 technicians: from there, custom development over 3–4 years is often cheaper than licences.

Discuss your field service project
We analyse your service processes and recommend the most economical app solution.
Core features are work order overview, customer data, time tracking and status updates.
Depending on needs: digital forms with signature, photo documentation, material tracking, route planning and integration with ERP or ticketing – the calculator prices these building blocks individually.
Orders flow automatically to the technician's device; recorded time and material go straight into invoicing.
That eliminates double entry and often accelerates invoicing by several days – one of the biggest measurable effects for service companies.
An app with order management and time tracking is productive in 10–14 weeks.
Complete solutions with offline sync, forms and ERP integration take 4–6 months – a staged rollout with a pilot team is recommended.
| Model | When it fits | Budget & flexibility | Typical risks |
|---|---|---|---|
| Fixed price (fixed scope) | Clearly defined scope, stable requirements, repeatable delivery. | Predictable total cost; little room for change without a change order. | Scope creep leads to change orders or quality trade-offs. |
| Time & Material | Discovery, legacy, evolving requirements, or close collaboration. | Maximum flexibility; budget transparent via hourly or daily rates. | Without prioritisation, effort can grow—backlog and reviews matter. |
| Retainer / maintenance package | Ongoing operations, updates, small features, and support. | Agreed capacity per month; predictable follow-on cost. | Large changes may still need a separate estimate. |
| Hybrid (milestone + T&M) | MVP or phased releases with clear go-lives, then iterate. | Core delivery fixed price; extensions on a time-and-materials basis. | Define contractually what is in scope vs. extra work. |
Calculators on this page provide indicative ranges; we choose the right model with you based on risk, scope, and planning horizon.
