Spline Seat-to-Retainer Ratio

Spline bills per seat: Hobby at $15 monthly ($12 annual), Pro at $30 ($25 annual), Max at $70 ($60 annual). The framework asks one question before quoting any 3D retainer: how many seats does delivery actually consume, and does the client fee clear that floor with margin left for revision cycles? A single Pro seat at $30 monthly supports the $580/mo Spline Starter 3D Presence offer, where one branded interactive scene, a no-watermark web embed, and a monthly refresh run on roughly 20 hours of setup plus 4 hours monthly. Add a second designer for collaborative scene work and the seat cost doubles before any client invoice exists. Map seats to roles first (scene builder, texture and AI generation, export and QA), then price the retainer against the highest tier the work genuinely needs. Agencies that skip this step discover the Max tier's Apple and Android exports were bought for a web-only client.
