Adding expenses for startup business paid with personal credit card without linking card to quickbooks.

Hi there, APSLLC22.

You can import the expenses as a CSV file so you don't have to link the account in QBO. You can download it from the bank's website or reach out to them to get a CSV copy .

Then, follow these steps on how to import the file in QBO:

1. Go to Transactions or Banking menu, then proceed to the Banking tab.
2. Click Upload transactions.
3. Select Drag and drop or click select files. Then, select the file you downloaded from your bank.
4. Click Continue and select the account in the drop-down list for QuickBooks account.
5. Select Continue and follow the steps on how to map the data.
