BillSend
BillSend makes it simple for tradespeople to send professional quotes and invoices — no accounting software required. Every document is automatically branded with your logo, colours, and contact details. Quotes convert to invoices in one click, with no duplicate data entry.
Customers approve quotes via a shareable link — no login needed — and pay directly through the invoice using Stripe. A pipeline view shows the status of every quote and invoice: sent, viewed, approved, or overdue, with automated reminders so you're not chasing payments manually.
Works across mobile and desktop, supports multiple currencies for international clients, and includes reusable templates for repeat jobs. A free invoice generator and quote calculator are also available without creating an account.

Vocalys
Vocalys is an Android app for independent tradespeople and field-service professionals who prepare customer quotes and invoices on site. Users dictate job details, review the structured draft, and edit descriptions, quantities, prices, and taxes before confirming. The app can scan supplier price labels, apply a chosen margin, and add materials to a quote. Users can include customer, business, payment, and deposit details, then share PDFs or send quotes for electronic signature through AgoSign. Accepted quotes can be converted into invoices; documents can be organized and exported for an accountant. Some viewing and editing work offline, while dictation, scanning, synchronization, sending, and remote signature need an internet connection. Country settings adapt document formats, currency, and tax fields. Vocalys is designed for plumbers, electricians, landscapers, service technicians, and other independent field professionals.
