The problem

The highest-intent page was the slowest page on the site.

Wing is a managed virtual assistant service processing thousands of scheduling interactions every month. Their booking page — the single highest-intent page on the site — was embedded with Calendly.

Calendly took 8–10 seconds to fully render. For a page where every second of delay compounds abandonment, that load time was a measurable leak in their pipeline.

Beyond speed, Calendly couldn't integrate with Wing's chatbot or IVR system. Prospects who came through the phone or chat were funnelled into a disconnected booking experience — a different interface, a different brand, a different context.

Before — Calendly

8–10 sec load time on booking page

No chatbot or IVR integration

Disconnected brand experience

No control over booking UI

After — Central Scheduler

Under 2 sec time-to-interactive

Native chatbot + IVR integration

Consistent brand across all channels

Full control over booking flow

Full disclosure: Wing and Central AI share a co-founder. This case study exists because the data warranted it — the 23% lift was measured independently via Convert.com's A/B testing platform, not internal reporting.

The switch

Live in under two hours. Tested, not trusted.

Wing's dev team implemented Central Scheduler in under two hours — one hour for initial setup, one hour for round-robin configuration across their sales team.

Rather than a hard cutover, Wing ran a controlled A/B test. The existing /schedule page kept Calendly. A new /schedule-new page ran Central Scheduler. Convert.com split traffic evenly and measured the difference.

Why this matters: Wing didn't "switch to Central Scheduler because they liked it." They ran a controlled experiment and let the data decide. The result was clear enough to make the permanent switch within one week.

Hour 1

Initial setup

Central Scheduler installed, booking page configured, branding applied.

Hour 2

Round-robin configured

Team availability rules, round-robin distribution, and calendar sync set up across the sales team.

Day 1

A/B test live

Convert.com splitting traffic 50/50 between Calendly (/schedule) and Central Scheduler (/schedule-new).

Day 7

Decision made

23% conversion lift confirmed. Calendly removed. Central Scheduler made permanent.

The result

23% more bookings. Same traffic. One week.

Results were clear within seven days. Central Scheduler rendered instantly — time slots loading in under 2 seconds versus Calendly's 8–10 second embed. Convert.com measured a 23% lift in visitor-to-booking conversion rate against the Calendly control.

Wing made the permanent switch immediately after.

The improvement came from two factors: speed and continuity. Faster rendering reduced abandonment on the highest-intent page. Native integration with Wing's chatbot and IVR meant prospects who started a conversation could book without leaving the experience.

The maths: If Wing's booking page receives 1,000 visitors per month and previously converted at 10%, that's 100 bookings. A 23% lift means 123 bookings — 23 additional high-intent meetings per month from the same traffic, at zero additional acquisition cost.
