Problem

Field work often ends with paperwork and delayed billing. Manual invoicing slows down cash flow and adds friction for both the technician and the client.

Solution

PayLoadApp enables on-site invoice creation using voice input or quick templates, then instantly shares the invoice document with clients. It also supports attaching proof photos when needed.

Who it is for

Field technicians (plumbing, kitchen or bathroom fixes) who often carry paper invoices.
Dog walkers who want to send professional invoices with proof photos.
Private tutors who rely on cash or bank transfer and need simple billing records.

For renters, the invoice can be shared with a landlord for reimbursement after a repair visit.

Core flow

Select a client or start a new invoice.
Use voice input or templates to add line items.
Generate the invoice and share it immediately.

Highlights

Voice-first data entry for hands-busy environments.
Template-driven invoices to keep billing consistent.
Fast document sharing with clients on the spot.
Optional proof photos to strengthen documentation.
