WISP Builder offers subscription levels to meet the needs of your firm.

Yes. The administrator is the only one that can add or delete users and establish what parts of the WISP builder they have access to.
No. Acknowledgement and review of the plan is a required function of an IRS WISP. So if you need employees to review and acknowledge your published plan, it is done electronically and these users are not given permanent logins, unless you set them up.
Of course. But given the nature of the service, the annual fee is not refundable. So use the tool until you move your service elsewhere.
