How come when I write checks from my account it doesn't subtract from my balance

Hi there, 

Welcome to the Community. It's vital you're able to write cheques and have the cheque amount subtracted from the chosen account. 

Creating cheques in QuickBooks Online lets you track expenses, and helps organize your chequing account and bank statement reconciliation.

To create a cheque:

1. Select the + New button.
2. Under Suppliers, select Cheque.
3. Choose the Payee from the drop-down list.
4. Specify the Bank Account where the money will be withdrawn.
5. Complete the cheque fields. (Note: The Memo field is optional. Text you enter in the Memo field appears in the Account history, on printed cheques, and on reports that include this cheque).
6. Select the Print or Preview option if you want to print the cheque.
7. Select Save and close or Save and new.

Tip: If you have a lot of cheques to write, it is easier to either enter them from the Account history, or download transactions directly from the bank.
