Context

Context

Over 140,000 restaurant owners across the U.S. rely on Toast point-of-sale (POS) devices to manage customer orders and payments. Within this flow, the tipping screen plays a critical role in the checkout experience, as restaurant workers’ earnings depend heavily on the gratuity customers choose at this moment.

Problem

After COVID-19, customers clenched their wallet, leading to a significant drop in tip income for restaurant workers. This decline introduced business risks for Toast, including potential subscription churn and ARR loss, reflected in decreases in tip revenue, tip completion rates, and POS retention.

Data analytics & Research

PM and I collaboratively conducted surveys and interviewed restaurant owners to empathize with their concerns and to investigate the causes of the tip decrease outside of external factors.

Pain point

Too many steps to complete tipping caused abandonment

Too many steps to complete tipping caused abandonment

Too many steps to complete tipping caused abandonment

Selecting a tip, signing, and tapping "continue" created unnecessary friction that drove customers to walk away

Hypothesis

Poor option hierarchy drove "No Tip" selection

Poor option hierarchy drove "No Tip" selection

Poor option hierarchy drove "No Tip" selection

Over 60% of tip selections were "No Tip," likely driven by its placement as the first and most prominent option on the screen

First iteration & Testing

1st iteration

Remove "signature" to simplify tipping

Hypothesis: If we reduce interaction steps by removing the signature requirement and completion button, it will increase tip completion rates.

Result

Removing the signature step increased tip completion rate, yet there was still room to improve overall tip revenue.

Second iteration & Testing

2nd iteration

Reframe choice hierarchy to guide higher tips

Hypothesis: If we prioritize higher suggested tips and reducing the visual prominence of “No tip”, it will nudge customers toward higher tips.

Total: $48.00 ($40.00 + $8.00 tip)

➡️ Prioritize higher suggested tips

➡️ Reduce visual prominence of “No tip”

Result

The iteration was successful as tip income increased beyond our goal expectation. Ultimately, we were confident to roll the redesign GA.

Third iteration & Testing

3rd iteration

Add a fourth suggested tip option

Hypothesis: If we add a fourth suggested tip, it will better accommodate user tipping ranges and increase overall tip selection.

Would you like to leave a tip?
Total: $50.00 ($40.00 + $10.00 tip)

Result:
More choices increased decision friction

Adding an additional tip option increased decision time, which led to more customers abandoning the tipping step without making a selection.
