The verdict
If people on your team paste data between tools, pick Zapier first. A form submission going into a CRM, a deal win announced in Slack and a new customer added to a sheet are quick to automate, and Zapier has a free plan to try. If the pain is a procedure that lives in someone's head and gets done differently each time, pick Process Street. It has no free plan, only a trial of its Pro plan. Plenty of teams end up with both: Process Street for onboarding, and Zapier moving the data that onboarding creates.
