My company A has a purchase of £10K, which is funded by loan from company B. A has yet to repay the loan. I can’t log a payment to the purchase because the drop down list has nothing like ‘company loan account’. Now my solution is not to log a payment, but create a journal to debit Credit Control Acc and credit Loans From B liability account.
You should not raise journals to the creditors control account. If Company A has not received the funds from Company B, and B has just paid the purchase directly, then what @QFSteve is suggesting is the best way around it. Just bear in mind at the end of the year though, the account should not be shown as part of your bank and cash balances, but should be shown in liabilities (either short or long term, depending on the agreement). If the funds have been transferred to Company A, then just tag the bank receipt as “something else not on the list” and credit it to a liabilities account (you can set one up specifically for Company B).
