Billabl.es is a simple invoice tracking tool I hacked together over a weekend which lets you invoice and track the process of an invoice, send messages and automatically send reminders to clients when an invoice is due (or overdue).
In its current incarnation I’ve opted for simplicity over anything fancy so it only has a basic set of features, and its still very much in beta. But as mentioned in previous posts, if you wait for something to be perfect you’ll never release anything.
Log in via your Twitter or Facebook account, create a client and then start sending them invoices (consisting of the very basic details). You can attach a url or upload a pdf which contains a printable invoice containing your detailed invoice.
Anyway, I find it useful and maybe you will too. Have a play!
For those interested, this site is built using a home grown (and I like to think quite powerful) PHP web services framework which I wrote because nothing currently out there did exactly what I wanted…
