Looking for Top Compliance/Onboarding Software

Has anyone found an effective software solution for onboarding candidates? In the healthcare field, I usually need to gather, review (often with back-and-forth communication), and finalize over 15 individual documents. Additionally, I often require hospitals and clinicians to also verify and sign these documents.

Is there a software out there that can streamline this entire process? I’ve tried Deputy, but it lacks the customization I need for my specific document workflow, and the format for signing documents doesn’t work well. Any recommendations would be greatly appreciated!
