Switch to BoldSign already! It's intuitive to use and affordable for small businesses. I never have to worry about the status of a document because with BoldSign I know. Plus, they let you program the frequency of reminders signatories receive. I'm so glad to have found it!

We’re using BoldSign successfully in our b2b SaaS platform - as it’s embedded to allow seasonal farm workers and their agribusiness employers to e-sign their employment onboarding documents for the first time. It’s part of the total solution saving the workers and HR managers 50% more time compared to their traditional pen/paper manual process.
