FAQ
What information do you need from me to get started?
Just a rundown of how your team currently handles jobs — how you receive requests, schedule/dispatch technicians, and invoice clients. If you have any reference apps or must-have features, share those too. I'll use this to map out the right structure before development begins.
Will the app work on both Android and iOS?
Yes. Depending on the package, I can build a cross-platform mobile app that runs on both Android and iOS from a single codebase, alongside a web-based admin dashboard for your office team.
Do you provide the source code?
Yes, full source code ownership is transferred to you once the project is complete and final payment is confirmed. Nothing is locked behind me.
How many revisions are included?
Each package includes revision rounds during development so the final build matches your workflow. Standard and Premium packages include additional revision rounds — exact numbers are confirmed once we scope your
Can you integrate payment gateways or accounting software like QuickBooks?
Yes. I can integrate payment processors (Stripe, PayPal, etc.) and connect your app to accounting tools like QuickBooks so invoicing and payments sync automatically.
Can the app be customized around our current HVAC or plumbing workflow?
Yes. The system can be structured around your actual process, including service requests, dispatch, technician assignment, work orders, estimates, invoicing, job completion and customer follow-up.
