Entering a vendor bill and making payment for a past period

Thank you for posting here in the Community, @FMW.

You’ll just have to enter the bill along with the date you received from your vendor in QuickBooks so it will be recorded.

Here’s how.

1. On the Home page, select Enter Bills.
2. Select the vendor and the date you received the bill
3. Choose the appropriate tab. 

• Expense: if you are recording a bill for expenses incurred by the business (ex. Utilities, Rent, and phone/cable service).
• Items: if you are entering a bill for anything that your company buys, sells, or resells in the course of business such as products, shipping and handling charges, discounts, and sales tax (if applicable).

      4. Select the appropriate account or the item then enter the amount.

      5. Once completed, click Save & Close.

If it’s a closed period, I recommend contacting your accountant so you’ll be guided on how to handle this situation.

 Here is an article that will help you understand about Journal Entry. Create a journal entry in QuickBooks Desktop.

 Let me know if you need further assistance. I am always here to help.

The best thing to do in this case is usually to fix your data, to enter the bill as you would have using the date the bill was issued.

If you already paid it, then create the bill payment in QB and use the date that was on the payment actually sent to the vendor.
