Common questions
How does Caddi connect Fiserv Premier and Square?
Fiserv Premier and Square just run together. You teach Caddi the way you'd teach a new hire: walk it through how you use them today, with no workflow builder to wire up. Caddi turns that walkthrough into a verified loop and runs it against Fiserv Premier and Square end-to-end.
Do I need engineering help?
No. Whoever does the work today walks Caddi through it on a call, the same way they'd train a new hire. Caddi builds the loop. No code, no IT ticket.
Is my data safe?
Yes. Caddi is SOC 2 attested. The AI watches and builds the automation, and once the loop ships it runs as deterministic code, repeatable and logged, with any model step scoped and reviewable.
Can Caddi connect Fiserv Premier and Square to other tools too?
Yes. Most Caddi loops span 3–6 tools. Once the first Fiserv Premier + Square loop is live, Caddi suggests other tools and other workflows to fold in.
How fast can it go live?
Typical first loops ship within a week of that first walkthrough. The Caddi team reviews every loop before it runs in production.
Does this work for RIAs and financial advisors?
Yes. Caddi runs Fiserv Premier and Square with the household as the unit of work, so plans, accounts, and activity stay tied to the right client and advisor. Firms most often start with onboarding, account maintenance, or reporting prep.
