Company

Company

PayFit is a SaaS company that automates payroll and HR processes for small and medium enterprises (SMEs) across Europe. From managing pay slips, leave requests, and social declarations to handling absences and expense workflows, PayFit simplifies what is traditionally complex, error-prone, and time-consuming.

Challenges

Challenges

Too many PRs and merges competing for CI resources caused frequent delays and inconsistent main branch stability.

Maintaining quality under scale — ensuring that every PR merged safely without slowing down development — became increasingly difficult.

Manual coordination around merge windows and QA checks created friction and slowed delivery.

PayFit's engineering team manages a large monorepo with hundreds of active contributors. As the company grew, merges and CI jobs multiplied — creating bottlenecks and uncertainty in the release process.

With Mergify's Merge Queue, PayFit introduced automated merge control and batching. Pull requests are now consistently validated and merged only when all checks are green, ensuring the main branch remains stable even under high load.

Before Mergify, we spent too much time manually coordinating merges. Now everything flows automatically — PRs queue up, tests run cleanly, and developers can move faster with confidence.

Previously, merge coordination required developers to manually manage when and what could be merged, often leading to blocked PRs or conflicts late in the process. With Mergify, this friction disappeared.

The merge queue continuously evaluates conditions and merges approved PRs safely, respecting priorities and branch protection rules — no need for human babysitting.

We no longer have to worry about merge order or timing. Mergify takes care of it. It’s one less coordination burden for our teams.

As PayFit's development organization scaled, maintaining reliability without compromising speed became a top priority. Mergify ensures that only validated code is committed to main, reducing regressions and broken builds.

This consistency gives engineers the confidence to ship continuously — even as the number of contributors and pull requests continues to grow.
