So I freelance along side my day-to-day job, and I have a couple of regular clients who are very slow at paying.
On my invoicing system I have set 30 days for payment, but payment usually arrived more like 30-60 days after invoice was delivered.
Invoices are only delivered once the job has been completed.
Knowing how these clients are slow, should I change the payment terms and chase earlier?
If I want to go full time freelance, obviously I don't want to be damaging my relationships with clients. However on the other hand, if I do go freelance full time I need to know when money is coming into the bank.
How can I handle these sort of clients? Or should I concentrate/prioritize more reliable clients?
