[Question] Invoice details

[SBC]

Could you guys please help me here.

What information do I need to display on the invoice I give to my customers. It will be "Cash Sales". Payment will be cash, EFT or Credit Card etc. via Pay Fast

I am not VAT registered so I don't charge VAT. But do I need to specify that the amounts already include VAT as charged by my suppliers who are VAT registered businesses.

Any input will be greatly appreciated!

Thanks
