Every hour billed.
Record your time as you work. Every hour accounted for.
Every receipt found.
Photo in, filed on the job. Back as one bundle when the accountant asks.
The invoice, the day the job ends.
Say "close Smith". She writes it. You send it.
You get paid.
She tells you who owes you and writes the chaser, in your name. Money you have earned shouldn't wait on your nerve to ask for it.
$17,500
The average small business is owed $17,500 in unpaid invoices.
You did the work, you spent the money. But the invoice went out late, the reminder never went out at all, and the money is still sitting in someone else's account. Billie prepares the invoice the day the job ends, keeps track of everything still due, and writes the chaser in your name — so nothing you have earned quietly slips away.

Not a general assistant. YOUR personal assistant.
Your business has its own way of working: call-out fees, materials markups, equipment hire charged to a shoot, or yacht invoices addressed to an owner's office. Billie works with your jobs, rates and terminology to keep your records organised and your billing accurate.
A general assistant
- Does tasks for a person
- Learns your trade from scratch, every message
- Writes numbers down
- Gives you a chat log
Billie
- Keeps the books for a business
- Speaks your trade: the jobs, the rates, the parts
- Logs against the right job at the right rate, and asks if she isn't sure
- Gives you the invoice, the receipts, and the list of who owes you
Your customers never hear from anyone but you. She writes it; you send it.
One Billie. Your trade.
Same assistant, your vocabulary. Four rooms, all open.
Nobody does this job for the paperwork
"Nobody gets into this business because they love the paperwork."
Built with one working yacht agent, from his own messages. Every trade since starts the same way: with someone who does the job.
From the people who use her
"The invoice went out the day the job finished. I didn't write a line of it."
"Four owners, four villas, and every statement arrives with the receipts attached."
"Every receipt landed on the right shoot. I stopped reconciling on Sunday night."
"By the time she sails, the invoice is written and the owner's office has it."
"Two invoices I'd already written off came in the week after I started."
One plan.
Unlimited jobs.
Everything Billie learns about your work, every job and every invoice.

Questions, answered straight
What does it cost?+
Free for the first week, no card. After that $99 a month at the founding rate (normally $199). Unlimited jobs and messages. Cancel by message.
Do I need to install anything?+
No. Billie is a WhatsApp contact. Save the number and message her.
Does she send invoices to my customers?+
No. She writes them. You send them, from your own number or email. Your customers never hear from anyone but you.
Does she work with voice notes?+
Yes. Most people use voice notes more than text.
Which trades?+
Trades, rentals and villas, film and photo, yachts, today. If you run jobs, buy things for them and bill for them, tell her what you do and she'll use your words.
What if she gets something wrong?+
Tell her. "The parts were 64 not 46." "That was Jones, not Smith." Nothing's final until you've seen a tick.
What about my accountant?+
Every closed job comes with a spreadsheet link. Send it on.
Is my data shared with anyone?+
No. Your jobs are yours. Nobody else who uses Billie can see them, and nothing is sold to anyone.
Your next job is already costing you money.
Message Billie when the first cost lands. She'll take it from there.
