Using data from various sources, forms in particular formats can be filled in by a data entry clerk.

A BPO or Data Entry company could offer forms processing services. They would fill out forms for clients in mass. There could be various types of forms with different standardized formats, and forms would often be on databases. Forms processing services is just standard data entry. One of the skills involved in forms processing is to take forms with spelling, grammar, and formatting errors, and correctly enter the information into a database.

Clients will put information in all sorts of odd ways into forms. Sometimes address information will be partially omitted, and other times some information will be redundant. Punctuation can be wrong, and information meant for two database fields can often get merged together. A good data entry keyer can easily straighten out this mess.
