Hi Tomi3,
Thanks for posting in the Community!
Choose the Bank/Credit account used to pay the expense transaction. And for the account/category use the Partner's or Owner's equity. Then, when you want to record the payment or get reimbursed for the expense, select transactions type as an expense, and then in the category column use the partner or owner's equity account.
For comprehensive steps, you can check this link to learn more about: Pay for business expenses with personal funds.
Drop by again in the Community if you have other questions on how to record your transactions.
