Build a prompt-based agent when conversations vary; build an AI Flow when every call must follow the same steps. A sales conversation or an open support call needs the flexibility of a well-written prompt. An order-status lookup, an appointment booking or a fixed qualification script works better as a node-based flow (greet → ask → look up → confirm → end) where the AI handles natural speech inside each step but can't skip or reorder them. Edesy supports both, with AI Flow templates for order status, appointment booking and lead qualification.

Side by side
| Prompt agent | AI Flow | |
|---|---|---|
| Structure | Instructions and rules in text | Explicit nodes and transitions |
| Handles unexpected turns | Well | Within each node; otherwise routes to fallback |
| Consistency across calls | Good with strong rules | Very high |
| Easy to audit | Harder | Easy: every call follows the same path |
| Best for | Sales, support, open conversations | Lookups, bookings, verification, fixed qualification |
Example flows
Order status: greet → ask order ID or use caller's phone → look up → read status → anything else? → transfer or end. If not found: ask again once, then transfer. See order status AI flow explained.
Appointment booking: greet → ask name → ask day → ask time → confirm → save → end.
Lead qualification: intro → ask need → ask timeline → mark qualified or nurture → transfer to sales or nurture close.
When prompts win
- Sales conversations with objections and questions in any order.
- Support calls where the caller's issue isn't known upfront.
- Early pilots, when you're still learning what callers say; a prompt is faster to change.
Make prompts reliable with explicit rules for closing, silence, names and pronunciation. See 10 prompt rules from real deployments.
When flows win
- Exact outcomes: the same fields captured every time.
- API lookups at a specific step (orders, appointments, accounts).
- Compliance: you can show every call followed the approved steps.
- Many languages: the same flow structure with language-specific prompts at each node.
A hybrid that works
Most production agents mix both: a flow for identify → look up → act, a prompt-driven node for open questions, and a transfer node for anything outside scope. Start with a prompt while you learn, then move the parts that settle into a fixed pattern into a flow.
Cost
Prompt agents and flows cost the same on Edesy: Rs 4-6 per started minute depending on your prepaid top-up.
