What do you consider unacceptable ? No payment for the last clean (6 weeks) or do you plod along not wanting to lose the contract?
We have a commercial job that gave us their payment terms after we were awarded the cleaning contract.
One month after the end of the month the job was done.
So if we do the job in the middle of the month then we expect to be paid 6 weeks later. However the cheques are only posted out around the 10th of the following month. This means that we should get the cheque 8 weeks after job completion.
We haven't been paid once yet according to their payment terms. There is always a list of excuses; the invoice hasn't been received (original emailed to the email address of the person who never received it, the order number given to use isn't correct etc, etc.) so we have to sent copies and await our cheque at the end of the following month.
We either accept it or dump it.
We took the job on as its internal only and we can do it during bad weather. The catch; we need to give them 2 days notice and the 2 day forecast has only been correct once this last year so far.
