You can transfer funds outside of QuickBooks and exclude the transaction from the bank feeds in Company 1, Georgiann.
Once the funds are deposited into your Company 1 bank account, you can manually transfer the funds to the bank account connected to Company 2 outside of QuickBooks.
Since the transaction will still appear in the bank feeds for Company 1, you need to exclude it to prevent discrepancies in your records.
Once the funds are successfully transferred to Company 2's bank account, you can link the deposited amount to the outstanding invoices within Company 2. For detailed guidance on linking deposited funds to invoices, refer to the article: Link a bank deposit to an invoice.
