There are a couple scenarios that can be thought of, your question is a bit obscure: You state the product is "invoiced" on January 31st, but you don't say when the product was sent out.
1. If the product was sent out prior to Invoice then sending the invoice makes absolutely no changes to the books as the transaction was recorded upon shipping. For example your company sold a computer on January 15th and is now sending an invoice for it, the entry would have been made on January 15th, not additional entry required until "after" payment is received.
2. If the product is being shipped with the invoice then it should be recorded the date the transaction occurs. January 31st being that date. It appear that you haven't received payment as of yet, hence the "invoice".
Either way on the above, the Journal Entry is as follows on the date the product is sent, whether it is invoiced or not.
Accounts Receivable (debit) $$$$
Revenue (credit) $$$$
Whether its January 1st, or 31st. The journal entry should be made the same day.
The exception to this rule is if you are using Cash Basis Accounting, then no entry is made until Cash is received for the product, regardless of date.

I'm thinking that marginal revenue product is the marginal revenue on one product, and marginal revenue is the marginal revenue on the whole firm sales... I'm wondering the same thing but the above response is incorrect. both terms imply values on one item as indicated by the "marginal"
Average revenue (AR): total revenue per unit of a product sold; Total revenue (TR): total number of dollars received by a firm or firm from the sale of a product; Marginal revenue (MR):additional revenue received result from the sale of an extra unit of product; Under perfect competition P=AR=MR and the firm's demand curve is flat.
Deferred revenue is recognized when cash received in advance for product or service that not delivered or rendered, so it's liability, once service fulfilled or product received Revenue Would be recognized Deferred revenue also Known as unearned revenue
