What would you class a fair time to pay a commercial invoice?

At current I give 21 Days is this to little or to long.

My smaller accounts normally pay on the day or within 5 days. The bigger stuff is on 30 days after they receive the invoice.

It's variable for me.  On my invoices I have "fouteen days unless a prior agreement exists between us".
There's one job that I do 6 weekly.  Sometimes they pay two invoices after I send the second one (with a reminder).  Other times I have to nudge them a bit harder and get 3 paid at once.  Not sure that's a good idea at the moment as they are connected with the airline industry.
Another one that I do monthly writes out their cheques on the last day of each month.  As I clean on the first weekend of the month that means a one month wait - which I'm fine with.  If I cleaned half way through the month I would still get paid on the same date.
Apart from that, they all seem to pay within the 14 days.
That reminds me.  There's a place that I stopped cleaning for because they were VERY bad payers.  I need to chase them for the last 20 quid.
