The challenge
The solution
PayFit supports over 20,000 customers across France, Spain, and the UK. For their Customer Success teams, message quality isn’t a nice-to-have; it is the brand speaking, one ticket at a time.
MerciApp is now part of the daily workflow: a lightweight browser extension that ensures teams send clear, consistent messages faster.

The challenge
Ensure consistent quality at full speed
Before MerciApp, PayFit was using several tools. Snippets were managed in one tool, corrections in another. Maintaining a consistent standard across hundreds of agents and thousands of messages was challenging.
Non-native teams spent too much energy on form. Endless reviews, phrasing doubts, and constant corrections made scaling quality feedback difficult.

“If I had to pick one word for the experience, it would be serenity.”
Angélique, Tool enabler @PayFit
The goal was clear. Unify tone and language level without adding friction to daily work.
Deployment was simple. The extension was installed, integrated into onboarding, and quickly adopted by both internal teams and the BPO. Day to day, this meant less time second-guessing and more consistent responses across the team.
Our solution
One tool for every response
Payfit needed a solution that solved two problems at once: ensure high-quality writing and standardize recurring responses. Enter MerciApp. It corrects grammar and spelling, maintains brand tone, and delivers snippets that save time across teams.
The rollout was straightforward. PayFit was guided through migration from their previous tool, snippet deployment, and initial fine-tuning. The goal was immediate usability with no disruption to workflows or tools.

“It reduces our teams’ mental load, gives confidence in their responses, and helps them phrase messages correctly.”

MerciApp in 3 words ?
“It’s become more than a reflex… it’s become second nature.”

Peace of mind, above all
Beyond saving time, PayFit highlights one key benefit: peace of mind. Teams no longer worry about whether their messages are properly phrased. They can focus on what really matters in customer relationships: explaining, reassuring, and guiding.

- Less stress sending messages because no one has to second-guess phrasing

“If I had to talk to another team about MerciApp, I’d just ask: Why aren’t you using it already?
