end client not approving timesheets

[Safe Collections]

As you have now left start I'd politely tell them exactly what you want (paid), state the contract does not have that deadline in it, with any accompanying emails from you that show this date was never happening. Inform them if time sheet is not signed and invoice paid, you will start dunning.

Lay out the issues in an email along with your invoices and demand payment. If you do not have deliverables and deadlines agreed as part of a contract it will be extremely difficult for anyone to argue you can be held to them.

If they refuse to negotiate or engage then you could potentially look at taking it further, but this will be complicated if the contract has not been terminated in line with your obligations...

Maybe worth talking to a debt recovery firm. I think one posts on here frequently though they don't know about dunning...

oops, I still can't think of the word I was aiming for!!
