Answer first
Start with the part of your funnel that matters most: qualifying leads, taking payments, or following up. The page builder, contact record, checkout, and follow-up must be evaluated as one operating path, even when more than one system is required.
Complete stack cost model
| Cost layer | Monthly input | Hidden variable |
|---|---|---|
| Core subscription | Plan price | Contacts, responses, funnels, seats |
| Connected tools | CRM, email, booking, checkout | Duplicate limits and usage tiers |
| Integration | Automation platform or developer time | Failures, retries, and data mapping |
| Operations | Team hours | QA, maintenance, governance |
Calculation
Complete stack cost = subscription + required connected tools + usage charges + implementation + monthly operating time. Compare that number against the revenue impact and the cost of a broken handoff.
