You can set your credit cards up as banks. Then you can record payments made with your credit cards.
If a Business Corporate Card, you would journal in the opening amounts owing in your set up month recording a negative amount for outstanding balances.
If a Personal Card that you sometimes use for company purchases make your starting balance zero (assuming that you company does not owe you from the legacy system).
Making a payment from a Credit Card
Your payment transaction entry screen would then provide the options to enter payments for purchases or service/supplies payments using your chequing accounts or anyone of your credit cards.
In this case with our personal MC credit card we purchased Photocopy paper from Business Depot for office use.
The Payment transaction is recording the amount spent into the Stationery Expense account.
Note my personal Citi MC is at zero and my TD Corporate Visa card reflects the amount that the company owes the financial institution that issued the card.
When I post this transaction the Citi Bank MC bank account will go into a negative $565.00.
As payments are made using these cards the negative balances will increase, thus showing the amount that the company owes the TD Visa Financial institution for the corporate expenses and what the company owes you for payments/purchases you have made on your personal account.
Making a payment to a Credit Card
To make payments to the TD Visa Card account, you set up the TD financial institution, that issued the card and bills the company monthly as a Creditor/Supplier.
You then make payments to them, charging the payment to the TD Corporate Visa Business bank account (#1155 in this case) which will then credit or lower the amount owed on the TD corporate credit card and debit your chequing account reducing the cash on hand.
If there are interest charges on the monthly invoice add a detail line to the transaction, charging the interest to your finance charges or interest expense account code in your chart of accounts.
For your personal MC credit card you periodically make a payment to yourself for the negative amount showing. The original payment transactions then act as a record of why you paid yourself, as well as correctly entering those costs into your company expenses and providing historic data of all payments made and payments reimbursed.
