Hey Keith,
Welcome to Method Keith, I hope your finding your way around the website ok. We have a lot of information on our forums and within our blogs.
To answer your questions,
Starter Edition
1, For any edition of method the starting price includes 1 Admin user.
2, API's will work with Method as long as you have the screens the API is communicating with. IE, Outlook API will not work unless you have the CRM edition of Method.
3, The Customer Portal is a part of our Method CRM Edition. This is not accessible from the Starter Edition.
Full Blown Edition
1, Same with the Starter Edition and CRM Edition, all versions come with 1 Admin user.
2, You can create a user that doesn’t go against your paid users. This is so you can assign work to those users without having to have them as a paid user. For instance on the Invoice screen you can assign reps, reps can be users. But maybe that rep doesn’t sign into Method.
3, Your Portal Users are billed based upon amount of time spent in the Portal. Portal users do not sign in the same way. A regular User is billed a set amount. The Customer Portal is used for quick viewing of but not limited to; Company File information, Recent Transactions, and Account information. A regular user is someone that would be in the system more frequently making changes or imputing data.
I hope this sheds some light for you.
