While my business account was about to be setup I paid for computer hardware via my private bank account. That hardware was used as components which got built into other devices. Those devices were now sold to customers.
What is the general way to record this?
Expense claims tab which is used to record business expenses paid from non-business funds such as private credit card etc.
I appear already as possible expense claim payer when creating an expense claim. I guess this is because I added myself as member of a capital account, correct? I assume I can use this entity instead of creating another expense claim payer (which would be myself).
That’s right. If you use capital accounts, every member under capital accounts can be expense claims payer too.
