Billing tips for freelancers
Invoice the day you deliver
The work is never more valuable to the client than the day they receive it. Sending the invoice the same day shortens your wait.
Use short, specific terms
'Due in 7 days (by Nov 14)' gets paid faster than 'Net 30' or 'due on receipt'. Agree on terms before you start.
Know whether it's been seen
An unopened invoice and an ignored one need different follow-ups. Read receipts tell you which you're dealing with.
