From a sentence to a paid invoice
Three steps. No spreadsheets, no forms to wrestle with.
Say it
Tell Lucy what you did, by voice or chat. She turns it into a clean, itemized invoice.
Send it
Send a branded invoice by email or text, or share a link your client can open anywhere.
Get paid
Your client pays by card on the spot. The invoice reconciles to Paid automatically.
Speak your language, bill in English
Describe the job to Lucy in Spanish or Portuguese, and she sends the polished English invoice your client expects. Built for the way US business really works.
Built different where it counts
Not just another invoice form. It's the things that actually get you paid.
Talk, don't type
A genuinely conversational assistant builds the invoice for you, while most apps still hand you a form.
Speak Spanish, bill in English
Describe the job to Lucy in your language; your client receives a polished English invoice. Built for how US business really works.
