What is workflow automation? (And why it fails quietly)
Workflow automation is software that runs a fixed set of steps on its own after something sets it off: a form arrives, a payment clears, a deal moves stage. Every decision gets made before you switch it on. The part people underestimate is that a half-broken automation looks exactly like a working one.
What actually runs
A workflow automation has three parts: something that starts it, a fixed list of steps, and rules for what happens in between. A form gets filled in, the automation adds the person to a list, sends a welcome email, posts in Slack. Same steps, same order, every time.
All the thinking happens up front. If the company name field comes through blank, the automation does whatever you told it to do about blank fields, which is usually nothing useful. Branching does not rescue you. Builders on Hacker News describe Zapier paths as one way: "once you're down a logical branch, there's no coming back to the main branch."
What it costs to keep running
Billing is per completed step, not per automation. Zapier counts a task each time an action finishes successfully, gives 100 tasks a month on the free plan, and starts paid plans at $29.99 a month for 750 tasks. Failed actions, triggers, and built-in pieces like Filter, Paths and Formatter are free. A 6-step automation firing on 400 forms a month burns about 2,400 tasks, several price tiers above where most people start.
Where it quietly stops
Nothing tells you an automation is half dead. Zapier only switches one off by itself once it errors 95% of the time and has run more than 20 times in the past 7 days. An automation that fails 4 runs in 10 never crosses that line and never gets flagged. Automate the paths your team has already run by hand a dozen times without variation, give each live automation a named owner who checks it monthly, and send anything that needs a judgement call to a person or to an agent that can stop and ask.
