If your company sells to the government and not set up to process level 3 detail, you could be losing out on business. Government buyers are encouraged to choose vendors who have the ability to process level 3.
I encourage you to consult with a level 3 payment specialist like Revolution Payment Systems. Setting up a level 3 merchant account not only makes you look more appealing to the government but you can expect to save 20-30% less on GSA, Commercial and Purchasing Cards.
There are other factors required to process level 3 and why its recommended to work with a certified payment processional. We have seem many cases where a merchant is passing level 3 and due to improper rate structure is not seeing the 20-30% savings on the Visa and MasterCard side.
PS. If you have quickbooks and need to process level 3, Revolution payment systems can help.
