FAQ
Do I own the source code?
Yes. The full source code is included with every package.
Can you add features after delivery?
Yes. Small changes can use the extras, and bigger features are quoted as a custom offer.
What do I need to give you to start?
A short description of your business, what you want to track, and any spreadsheets or documents you use now.
Do you offer support after delivery?
Yes. Every package includes a 6-month warranty. If something I built doesn't work as agreed, I'll fix it for free. This excludes new features, design changes, extra data entry, and issues caused by others' edits or third-party updates. Those I can quote separately.
Where will the app be hosted?
I can host it for you. Hosting is optional and billed separately through Fiverr as a custom offer, covering the cloud costs and monitoring. Or I deploy it to your own Vercel and Supabase accounts so you own everything. Ask me which fits.
