Intelligent process automation vs RPA (and when RPA still wins)
RPA runs fixed rules against fixed screens, so every unusual case becomes a ticket for a person. Intelligent process automation adds document reading and language models, so the case gets handled instead of queued. The trade is real: measured against RPA, the AI layer builds far faster and runs less reliably.
Intelligent process automation (IPA) is sold as the fix for a stalled robotic process automation program. Half of that is right. The two fail in opposite directions.
IPA vs RPA at a glance
| Aspect | RPA | IPA |
|---|---|---|
| Handles | Fixed screens, structured fields | Documents, email, free text |
| Fails when | A form or selector moves | The model misreads intent |
| Build effort | 240 minutes | 15 minutes |
| Measured reliability | 10 of 10 runs | 6 of 10 runs |
| Cost shape | Robot licence, $25/month up | Per-run model spend |
When RPA still wins
Reliability and unit cost. A 2025 Technical University of Liberec study ran three enterprise workflows through UiPath and Anthropic's computer-use agent, 10 times each. UiPath finished 10 of 10 runs on all three. The agent hit 9 of 10 on data entry, 6 of 10 on document extraction, and failed the third outright. It also ran slower: 203 seconds against 20. A process running thousands of times a month against a stable screen gains nothing from judgement.
When IPA earns the budget
Build time and exception load. That same study spent 240 minutes building document extraction in UiPath against 15 minutes of prompting the agent. The 16x gap is the return: an RPA program costs people, not licences. UiPath's entry tier is $25 a month for 2 robots; the cost is developer time rewriting selectors.
How to choose
Count the exception queue first. If a handful of cases in a hundred need a human on a stable screen, RPA is cheaper and IPA is a tax. When a third of cases need someone to read and decide, more rules will not close the gap. Teams already on Zapier or n8n sit closer to IPA and should rebuild branch-heavy paths as agent goals before buying robot licences.
