Yes, it is.
That is not recommended. You sacrifice visibility and reporting options.
Yes, it is. It goes directly to functionality of the Expense Claims tab.
To add to what @alasdair has written, you have choices, depending on your legal form of organization and the setup of your chart of accounts. All these are described in the Guide about expense claims: https://www.manager.io/guides/6898:
- If you have capital accounts for members/partners/owner, those persons will automatically show up as expense claim payers. Expenses entered will be automatically credited to their capital accounts. The advantage is that you do not need to define expense claim payers separately. The disadvantage, though small, is that you will not see these claims reflected in the Expense Claims Summary report. Instead, they will be reflected in the Capital Accounts Summary.
- If you are a proprietorship and are using simplified equity accounting (https://www.manager.io/guides/6971), you will need to define expense claims payers. Then, if you do not want to reimburse, you will need to clear the Expense claims liability account periodically with a journal entry, debiting Expense claims and crediting Owner’s equity. This might be monthly, quarterly, or annually to suit your needs.
- You can also mix the two approaches. This would be suitable if you usually allow the expense to stand as an additional contribution of capital, but anticipate eventually wanting to reimburse. This decision can be made later. That is, you could start with the capital account approach and add separate payers if necessary in the future.
