Bulk Services — Cowlendar

Problem

Merchants using Cowlendar (Penida.io's booking app for Shopify) had to create services one by one. For service businesses with larger catalogs — salons, studios, clinics — this meant dozens of repetitive actions. The pattern showed up in support tickets consistently, and it was costing us onboarding completion rates.

Approach

I translated the pattern from support feedback into a concrete product proposal, then went further: I built a functional prototype in Next.js using Claude to validate the UX before proposing it to the CTO. I wanted to hand over working evidence, not a mockup.

1. Step 1: Business type selection
2. Step 2: Define the services (name, duration, price) in bulk
3. Step 3: Set availability rules once, apply to all
4. Step 4: Advanced settings (teammate assignment, capacity)
5. Step 5: Confirm and create

Solution

A live prototype that creates services via the Shopify Admin API, demonstrating the full wizard flow with real data and real constraints.

Result

• Validated with the CTO using functional evidence, not mockups.
• The feature was accepted into the roadmap.
• Reduced the discussion loop from "can we build this?" to "how do we ship this?".
