Work order app trial period: what to look out for during your trial?

You don't test a work order app to see if it “works well,” but to prove that it leaves you with less hassle, fewer errors, and faster invoicing. And that only works if you handle the trial period strictly: with real jobs, real people, and clear metrics.

For small construction and installation companies, that trial is especially important. You don't want to spend months implementing only to find out later that one detail is missing, such as incorrect trip logging or an approval step that doesn't fit your way of working.

Start with a simple baseline measurement (otherwise you won't measure anything).

Before you start the trial, document how you currently work. Not in an extensive report, but simply in figures that you can compare tomorrow.

Note, for example, how long it now takes from “job finished” to “work order complete” and to “prepare invoice”. Also count how many corrections you make on average: missing hours, forgotten materials, unclear descriptions, lost slips.

One sentence that often comes too late: you don't test an app, you test a process.

Test with real scenarios, not with a demo job.

A work order app can always look neat in a demo. In practice, however, it is messy: multiple projects in one day, ad hoc extra work, an employee who doesn't feel like typing a lot, and a customer asking questions afterwards.

Therefore, plan your experiment around a few recognizable situations:

• small job with a short turnaround time
• a multi-day project with various employees
• additional work with photos and notes
• trips to multiple addresses in one day

Make sure you include the back office as well. A work order app stands or falls with what happens in the office: checking, approval, export, and preparation for invoicing.

Usability: how quickly can someone do it without explanation?

Ease of use sounds subjective, but you can make it very concrete. Have an employee who “doesn’t like apps” fill out a work order without a manual. See where he or she gets stuck.

Pay attention to details that make the difference in builds: large buttons, few steps, logical terms, and no unnecessary fields. At Werkbriefje.app This works via a mobile app and a desktop environment, with an interface focused on quickly registering hours, materials, trips, and project information.

Also check how to install and deploy. A progressive web app (PWA) that you install via the browser can be useful because you are not dependent on app stores and updates are often quieter and faster.

A few extra minutes per work order seems like little, until you do it with three people every day.

Functionality: the basics must be complete

In a trial, you primarily want to know if the core is fully suitable for your work. For most small construction companies and freelancers, it comes down to the same set:

• hours (incl. travel hours, leave, sickness and overtime where necessary)
• material per project
• mileage registration (preferably with automatic calculation)
• additional work capture with photos and notes
• manage projects and prepare work orders for invoicing
• planning that aligns with how you look ahead

Werkbriefje.app focuses precisely on that foundation: one system for hours, materials, trips, overtime, and planning, with direct insight in the dashboard.

During testing, pay close attention to “almost” functionality. For example: you can register mileage, but not per trip, or you cannot see in a verifiable way how the distance was calculated. Or you can add photos, but they do not appear logically in the proposed invoice.

Reliability: deliberately test under poor conditions

You only notice stability when you put the system under pressure. During the trial, have multiple people register simultaneously, let projects grow, add many lines of material, and test on a construction site with moderate range.

Things to keep an eye on:

• Does the app remain responsive when there is a lot of data?
• Are you getting error messages when saving or synchronizing?
• Do you lose data if someone logs out halfway through?
• Are changes properly forwarded to the back office?

Real-time synchronization is nice, as long as it remains predictable. If you have to doubt afterwards which version is correct, you are back to square one.

Reporting and invoice preparation: is the story conveyed to the client accurate?

A work order is only “finished” when you can create an invoice from it without extra cutting and pasting. During the trial, you therefore check not only the input but also the output.

After a week of testing, open the overview per project. Can you quickly answer questions such as: how many hours, what materials, which trips, and comments regarding additional work? And can you present that information neatly to the client or accounting?

A simple table can help record your findings per app. Use it during the trial and add to it every week.

Integrations: only connect when the foundation is right

Many companies want to connect directly with accounting, payroll, or planning. That makes sense, but don't make it too difficult for yourself in week one.

Start with export and basic transfer: can you extract the data in a format your administration understands? Only then should you look at APIs or direct connections. Werkbriefje.app indicates that integrations are possible (including towards administration and payroll), but during a trial period, you primarily want to determine which connection you really need and what is “nice to have”.

A practical approach: first test whether your invoice proposal is correct. Only then proceed to automate.

Privacy and rights: who can see what?

A work order app contains customer details, hours (often including leave and sick leave), and sometimes photos of situations on location. This requires clear permissions and logins.

Check during the test:

• Does every user have their own login?
• Can you set roles (technician only sees their own work orders, office sees everything)?
• Can you export data if you ever want to switch?
• Is it clear how data is stored and secured, and what is arranged in terms of the GDPR?

You don't have to be a lawyer to test this, but you do need to know what you can count on as a company.

Support: ask questions intentionally and measure the response

You don't recognize good support by a nice promise, but by what happens when you get stuck. The trial period is the perfect time to reach out: not because you want to cause problems, but because you want to know how things go when you encounter friction.

Ask a few real questions that fit your situation. Think about setting up hours, adding fields, or an explanation of an export.

• Response time: How quickly do you get an answer on a weekday?
• Quality: Is the answer immediately usable, or does it remain vague?
• Thinking along: Are you asked about your process, or do you only receive a link?
• Updates and fixes: How are bugs or areas for improvement handled?

Werkbriefje.app offers, among other things, demos and personal support; a trial allows you to effectively test whether it feels that way in practice as well.

Trial limitations and costs: what is included and what is not?

A trial period is only fair if you know what you don't see. So explicitly ask whether all features are available, or if certain things will be behind a paywall later.

At Werkbriefje.app lies the price indication around €12,50 per user per month (excl. VAT). Check during the trial period how that works out as you grow: extra employees in busy months, or a temporary extra user at the office.

Also pay attention to potential extra costs for customization or specific integrations. Customization can be valuable, but only if you are first certain that the standard workflow is correct.

Make the trial measurable with 5 KPIs that you actually track.

If you take only one thing away from this approach, let it be this: choose few KPIs and really track them. You don't need to build dashboards; a shared note or spreadsheet is enough.

1. Work order turnaround time: from job finished to work order complete
2. Invoicing lead time: from complete work order to preparing invoice
3. Corrections: number of adjustments per week (hours, equipment, trips)
4. Completeness: percentage of work orders that are correct on the first try
5. Acceptance: how many employees are working along without resistance after week 2?

After two to four weeks, you usually already have a pattern. Not perfect, but clear.

A practical setup for your trial (without much overhead)

Choose a short period in which you have enough variety, but are not in the middle of the greatest chaos. A trial works best if you bring rhythm to it.

• Week 1: setup, 2 projects, basic registration
• Week 2: additional work, photos, approval and planning
• Week 3: export, invoice preparation, exploring integration
• Week 4: evaluation with team, open points and choices

Also schedule one fixed time per week with the field service team : 10 minutes of feedback, three questions, done.

If, at the end of the trial, you notice that the office can invoice faster, work orders are more complete, and discussions about hours decrease, then you haven't tested a “nice app,” but a way of working that provides peace of mind. And if that isn't the case, you at least have a clear understanding of where the bottlenecks lie and what you want to report back to the supplier before you get stuck with anything.
