How to read these numbers
AI development quotes on the open market often land between $50,000 and $150,000 for a first production build, before support and iteration. Hiring two senior engineers in the US or UK commonly exceeds $240,000 in year-one payroll when you include recruiting and benefits.
The FusionSync partnership path is different. You validate with a free POC, quote published tiers on sales calls, and pay implementation only when your client closes. Monthly support starts at $300, $400, or $500 per client depending on tier, with volume discounts once you pass two active clients.
What the calculator includes
Implementation uses tier midpoints: $350 for Tier 1, $600 for Tier 2, and $900 for Tier 3. Support uses the discount bracket for your selected active client count. Year-one total adds twelve months of support to implementation across all clients.
What it does not include
Your agency client fees, optional ownership transfer at milestones, product maintenance after ownership, or out-of-scope hourly work. Those are commercial decisions above the fulfilment floor.
When partnership wins
Agency owners with paying clients in one vertical usually beat build-first economics until tier scope breaks or ownership milestones justify in-house control. See the partnership hub for the full phased model.
