User is looking to match a deposit to an invoice to mark that invoice as paid using Cloud Feeds.
Cloud Feeds deposits can be matched to Core deposits. Currently, Core does not allow for a cloud deposit to be associated with an invoice in order to create a payment entry.
If a bank statement with purchases and receivables is downloaded into Cloud Feeds, you can match your entries to bill payments, checks, credit card transactions, and deposits. We do not associate them with vendor bills. Also, any expenses you have can only be matched to credit card expenses.
