Inkit says it supports SOC 2 and HIPAA compliance, with IL4/IL5 compliance available to enterprise customers. Automated records-retention schedules and policies are also supported. The free plan costs nothing and includes three signature requests per month, one seat, and 10GB of storage. Listed plans include Personal at $20 a month and Standard at $30 a month; Enterprise pricing is customizable. The pricing note says paid plans start at $15/user/mo and includes a 30-day trial; the comparison also lists 14-day and 30-day trials for paid plans.
