The challenge

A growth-stage workflow SaaS business with $5M–$30M ARR sells $36,000 annual contracts to mid-market operations teams.

What WKND built

Ad groups by buyer question: Workflow-specific evaluation (40% or $60,000); Product comparisons and alternatives (35% or $52,500); Integration and migration decisions (25% or $37,500).

Landing page

Build one page per workflow or comparison. Explain who the product fits, core integrations, implementation requirements, pricing approach, and demonstration outcome. Ask for company, role, team size, and use case; qualify before the calendar when appropriate. Keep the form short enough to complete on mobile.

Intake and follow-up

Route valid business inquiries to an owner with a response SLA. Send relevant proof and an implementation brief before the demo, then follow up on the agreed next step. Preserve demo attendance, opportunity acceptance, proposal, closed-won, activation, and expansion as separate stages.

The lesson

Larger contract bookings do not eliminate the sales cycle or the need for working capital. Show paid acquisition, allocated SDR and AE costs, implementation readiness, and payback from activation. Keep bookings, recurring revenue, collections, and recognized revenue distinct.
