I can share some information about bank deposits and invoices, @Tiv4.

At this time, you can only link the bank deposit to an invoice. You can go to the register to find the deposit entry in your bank register. Then, apply the deposit entry as an invoice payment.

Here's how to find and edit the deposit: 

1. Go to the Gear icon (⚙), then select Chart of accounts.
2. Find the account you deposited the payment to, then select View register.
3. Find and select the correct deposit. Then select Edit.
4. In the Add funds to this deposit section, find the deposit.
5. From the Received From dropdown, select the customer from where the deposit came from.
6. From the Account dropdown, select Accounts Receivable.
7. Click on Save and close.

Then, to apply the deposit entry as an invoice payment:

1. Go to the + New and Receive payment.
2. From the Customer dropdown, select the customer’s name. 
3. In the Payment date field, enter the day you received the payment.
4. In the Outstanding Transactions section, select the invoice you need to mark as paid.
5. In the Credits section, select the deposit.
6. Select Save and close.
