The billing routine worth copying
Issue on a fixed day rather than when you remember. A weekly or fortnightly billing slot means work is invoiced while the client still recognises it, and it stops the end-of-quarter scramble where three months of small jobs go out at once.
Then a second, shorter slot for the unpaid list: who is overdue, by how many days, and who gets a follow-up naming the invoice number and the due date. Fifteen minutes a week beats an afternoon a quarter, and it changes your cash position more than any pricing decision you will make this year.
