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.
FusionSync runs two tracks. The Partnership Model lets 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. Ownership transfers at $15K and $50K cumulative qualifying revenue milestones.
The Custom Build track is for one-off projects where you want to own the IP from day one. Same tier pricing, but you pay upfront and there's no partnership structure.
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 or projects.
What it does not include
Your agency client fees, optional ownership transfer fees at milestones, product maintenance after ownership (Path A), or out-of-scope hourly work. Those are commercial decisions above the fulfilment floor.
When each track wins
Partnership Model: Agency owners who sell AI and automation services, have a pipeline in a vertical, and want to scale fulfilment without fixed payroll. Ownership at revenue milestones is the long-term upside.
Custom Build: True one-off projects with defined scope where you want immediate IP ownership and no ongoing partnership structure.
In-house: When daily roadmap control in-house beats partnership economics and you have utilization to justify payroll.
