Hi there, onesimpleruleltd.

I'm here to guide you in recording that transaction. First, you'll need to create a journal entry for the business expense you paid for with personal funds. Here's how:

1. Click the + New button, then choose Journal Entry.
2. On the first line, select the expense account for the purchase.
3. Enter the purchase amount in the Debits column.
4. On the second line, select Partner's equity or Owner's equity.
5. Enter the same purchase amount in the Credits column.
6. Hit Save and close.

Once done, follow these steps to reimburse yourself via expense or cheque:

1. Click the + New button,
2. Select Expenseor Cheque. 
3. Pick a bank account to use to reimburse the personal funds.
4. In the Category column, select Partner's equity or Owner's equity.
5. Enter the amount to reimburse.
6. Hit close or Save and new.
