Should you buy a self-serve AI agent subscription or work with a specialist that builds agents for you? Pros, cons and a decision checklist.
The short answer
Self-serve SaaS agents are fast and cheap to start but generic. Specialist builders cost more up front but fit your workflow and own the integration work. Choose based on how specific and valuable the workflow is.
Key takeaways
| SaaS AI agent | Specialist-built agent | |
|---|---|---|
| Start time | Minutes | Weeks |
| Fit | Generic | Tailored |
| Integration work | You | Provider |
| Pricing | Subscription | Scoped project + running fee |
Is the workflow company-specific? Does it touch several internal systems? Is the value large enough to justify scoping? If yes to all three, a specialist build usually wins.
Show a working agent on your workflow before you sign, build a business case and handle procurement and security. That's the process Switch describes, and a useful benchmark when evaluating any provider.
Ask about ownership of instructions, data and integrations before signing.
