Get Paid Faster: Client Portals, QR Codes & Partial Pay
Sending an invoice is the easy part. Almost any tool can generate a PDF with a total and a due date on it. The harder problem — the one that actually determines whether you get paid on time — is everything that happens after you hit send...
How to Track Billable Hours and Invoice Automatically
If you bill by the hour, there's a very specific kind of friction that happens once a month: you open your timer app, scroll back through a few weeks of entries, do some mental (or spreadsheet) math to group hours by client, and then ret...
