I've been doing it for 60%.
I don't return to collect.
I don't take the hit for his bad debts.
I collect any cash and cheques at the point of cleaning.
I forward the cheques but deduct the cash from my invoice total as posting cash isn't on.
I phone/text beforehand if any access issues.
This was sort of OK as his prices were higher than mine.
Much less OK when he registered for VAT and didn't add it to half the jobs (I took a hit on pay with those ones.
Even less OK when VAT rose so we shook on it, gave notice, and I move on.
Nice guy but I can't afford to carry more VAT - effectively working for 12% less than a couple of years ago.
Also, the work is more troublesome than mine as there are a high proportion of custies who need to be pre-notified, and a fair few of them seem to "forget" a lot. Also, some jobs have parking issues that I wouldn't do on my own work.
It's been helpful for cashflow but I need to get out there and get in more work of my own.
