About this gig

Still controlling your stock, sales or registrations on paper or messy spreadsheets? I will build a simple, easy-to-use web app for your small business that works on any computer or phone.


Examples of what I can build:

- Inventory control with low-stock alerts

- Sales and orders registration with reports per client or period

- Customer, member or product registrations with search

- Shared consumption control (e.g. office snacks with Pix/QR code payment)


What you get:

- Clean, responsive interface that works on mobile

- Source code included and a short user guide

- Deploy on free hosting (Premium) so you pay nothing monthly

- 20+ years of IT experience, English and Portuguese (atendo em português)


Please message me before ordering and tell me how your business works today, so I can recommend the right package.
