Cell App Builder Resale Margin Ladder

Cell App Builder's vendor pricing sets a hard floor under every client retainer an agency quotes. The published tiers run $15 USD monthly, $16.67 USD monthly on annual billing, and a one-time $400 USD, while the blueprint lists Starter at $29/mo, Pro at $69/mo, and Agency at $149/mo as vendor costs. A Starter offer billed at $280/mo against a $69/mo Pro seat leaves roughly $211/mo before delivery labor, and the blueprint budgets 12h setup plus 2h/mo to run it. That gap is the ladder: each rung is a vendor tier matched to a client type. Restaurants and salons needing push notifications and QR coupons sit on the low rung; multi-location retail or schools needing e-commerce and calendar embeds justify the Agency tier. Quote the retainer only after the tier is fixed, because the one-time $400 USD option changes the break-even month entirely.
