{faq}
Questions we often get.
Why custom instead of off-the-shelf software?
If off-the-shelf software solves your problem, we'll tell you. Custom makes sense when your processes are your competitive edge, or when you've spent too long bending to tools that don't fit.
Does it work on mobile?
Yes. All our applications are responsive and can be installed as a PWA if you need it.
Can we start small?
That's what we recommend: a first version with the essentials, in production as soon as possible, then evolve it based on real usage.
What about our existing data?
We migrate it from your spreadsheets or previous systems as part of the project.
