    Know where it stands

    See when your client opens it, and mark it paid when the money lands.

What it does

Small on purpose: the things a freelancer does every week, done well.

Hours that bill themselves
Tracked time becomes invoice lines at the client's rate, rounded up to 15 minutes, and reads as “1 h 30 min”, not “1.5”.
A page, not an attachment
Your client gets a link that opens anywhere, no account needed: the amount, what it's for, and your account number one tap from their bank app.
Email or WhatsApp
Send it by email from your business name, with the PDF attached and replies coming to you. Or share the link wherever you talk to the client.
“Viewed” means viewed
The invoice turns Viewed when your client first opens it, not when you check it yourself. No more “did you get my invoice?”.
Your name on it
Your logo or a badge in your colour, your business name, and how to pay you, on the page, the PDF and the email.
Money that adds up
Amounts are kept in whole kobo and cents, never fractions, so a total on your phone matches the page your client sees, to the last kobo.
On your laptop too
The same account on the web: clients, the timer and invoices, and what you're owed at a glance. On an iPhone, add it to your home screen.

What your client gets

An email from your business name, not from us: the amount and when it's due, a button to the invoice page, what it's for, line by line, how to pay you, and the PDF for their records. When they reply, it comes to you.

The page it opens is the invoice at the top of this one: the same slip, in light or dark, with ₦1,275,000.00 as the headline and a stamp once it's paid.

Your clients, your business

No ads, nothing tracking what you do in the app, and nothing sold. Each account can only ever read its own records, enforced by the database itself. Delete your account and everything in it goes, straight away.

The Android app arrives in December.

Not on Android? Everything works on the web too, on any phone or laptop.
