Stack TCO Calculator
What it actually costs to run a B2B stack for three years.
Twelve minutes of guided questions. You get a defensible cost band across licensing, integration, ops, support, and customization, anchored on Forrester, Gartner, and Acro engagement data.
Mid-market B2B replatforms blow budget 60% of the time, average overrun $480K (Forrester, 2024). A defensible three-year band before you sign turns procurement from a gut call into a real conversation.
Sample TCO band
3-year$35M wholesale distributor, BigCommerce + NetSuite
$760K - $1.4M
Most defensible midpoint: $1.05M. Integration is 38% of spend.
Where cost concentrates
Licensing scales with users + integration count. Six connections push you above the platform's base tier.
Watch-out for procurement
Self-implement looks cheaper at signing. Rework on integration scope drives the high band 50%+ above mid.
