We get asked for discounts for cash all the time on work done, tyres etc.Then you obviously haven't got the concept?! The above is the true definition of 'cashie' understood by both trade and customer. Nothing written down, nothing recorded, just a handshake required. If you wrote those things down then there was obviously a communication breakdown between you and the tradie, wether intentional or not. If you ask for a tax invoice after reneging your choice for cash - expect the tradie to issue you with a partial payment on an invoice (probably charge you more), then add GST. What comeback have you got then?
I have a number of responses in my head I could use, and depending on the person; I have used some of them.
One is; "When you go to the supermarket, and take your trolley of items to the cashier, what do they say when you ask them; 'How much for cash?'"
Another is; "Yep; discount for cash; but no invoice and no warranty". That changes their mind pretty fast.
One time, a bloke asked me if I accepted cheques. I said "Sorry; we don't accept cheques unless it's a bank cheque"
He then told me I would take his business cheque if and when he bought his car for the tyres he needed.
I said; "No worries; when the cheque clears, you can come and pick up the car".
Forgetting to give you an invoice is different to agreeing to not provide an invoice because you both agreed to a cash deal.Now how about if you have their ABN, business details etc, they forgot to give you a invoice (or never intended to) and you make a diary entry on the cost of the job and claim it on tax
We often get folks calling and asking for us to send them another copy of an invoice they lost, but need for tax deductions.
This would be a similar scenario to forgetting to provide an invoice; you don't have one, but need a copy.
Similar - but different - to the scenario of reneging on the cash deal; we often get folks wanting "a basic service" to keep the cost down....then at the end when they pick up the car they nonchalantly ask; "Did you to stamp the service book?"....Good one.
