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.
