To not work on a contract til first payment made

[Drowningnotwaving74]

Been working as an affiliate with a consultancy.
Initially I was through an agency and she was pants at signing timesheets
Gone direct and not been paid aibu to not work until paid

Is it just that they are disorganised, but can actually pay you? If so tbh I would just work (this might be unfashionable opinion amongst contractors)

Is it ongoing work you submit invoices for or a timed one off contract

Ongoing work

If they need you more than you need them, then sounds ok. They are in the wrong, clearly, and you can choose who you work with.

They already owe me 2k I'm just worried about it being more

How long is the 2k for? If you’re on 500 a day then Yabu but if you’re on minimum wage part time and they’ve not paid you for over a month then YANBU

Invoice them

It's the invoice they have not paid

What are their payment terms and have they exceeded them?

OP, it depends how long the invoice was unpaid for.
I am waiting now for my monthly timesheet from September to be paid, a week overdue, and I am an employee. Some people are just really really bad at admin. I'd send a gentle reminder, but won't burn bridges.

No more work until your paid send a reminder stating as I'm sure your aware this invoice is overdue I cannot continue work until payment is made

Well what are the terms of the invoice and how late are they in paying? Is it 30 days and they are a day over? Or is it 30 days and they’re a week over?

No more work until it’s paid, would be my response.
