If a director has purchased equipment for the business do I add the supplier invoice as an expense? how do I transfer this value over to long term loans?

I appreciate you coming here, @jansmith112-me-c. I'll provide some details on how to enter the purchase equipment into QuickBooks Online.

Equipment can be recognized as a fixed asset since it's an item that can't be deducted as an expense when purchased.

Here's how to set an asset:

1. At the top, click the Gear Icon.
2. Select Chart of Accounts from the drop-down menu under Your Company.
3. Select New in the top right corner.
4. Select either Fixed Asset or Other Account Type from the Account Type drop-down menu.
5. Then click Next after selecting the detail type that best defines the asset.
6. Give the account a name.
7. The system will generate a Depreciation sub-account for the item if you check the Track depreciation of this asset box.
8. Fill in the cost fields as they were originally.
9. Choose Save and Exit.

Moreover, you can create a liability account for the payable loans in the future. Here's how:

1. Navigate to Gear > Chart of Accounts.
2. Select New.
3. Select Other Current Liabilities, Current Liabilities or Long Term liability.
4. Select the detail type Loan Payable.
5. Give it a meaningful name, like "Equipment Loan from Finance Company Name".
6. Select Save and Close without entering an opening balance.

Enter the check and apply it to the asset, just like you did when you paid the provider for the equipment directly.

Here's how:

1. Select New (+) > Check.
2. Fill in all relevant information on the Check screen.
3. On line 1, enter the loan's liability account and the amount of the payment going to the principal; on line 2, enter the interest expense account and the amount of interest being paid.
4. If there are any additional fees, enter them on the following lines, along with the appropriate account.
5. Choose Save and Exit.

In addition, I suggest consulting your accountant to help you track your books correctly.
