Common questions
How does Caddi connect Bill4Time and Klaviyo?
Bill4Time and Klaviyo 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 Bill4Time and Klaviyo 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 Bill4Time and Klaviyo to other tools too?
Yes. Most Caddi loops span 3–6 tools. Once the first Bill4Time + Klaviyo 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 law firms?
Yes. Caddi runs Bill4Time and Klaviyo with the matter as the unit of work, so documents, time, and communications land against the right client and matter rather than in a general folder. Firms most often start with intake, document filing, or billing prep.
