Why a custom business application?

Your processes run on Excel, a generic ERP or a no-code tool that has hit its ceiling. Every file requires re-entering data, errors multiply and nobody dares touch the central spreadsheet. A business application built around your processes removes these frictions: it automates what should be automated and grows with your activity.

  • A tool aligned with your real processes, not the other way around
  • Full ownership of the code, no license or dependency
  • Measurable gains in processing time and error rates
  • A scalable foundation that follows your team's growth

Why PeakLab?

Because we write quality code, we make our clients autonomous, and we build apps that generate cash. Period.

Our method, from audit to evolution

Six steps to move from a tool you endure to a tool that works for you.

01

Audit of the existing

Mapping of your processes, Excel files and current tools to identify time losses and risks.

02

Business design

Workshops with your teams to model the workflows, roles and management rules specific to your activity.

03

Custom development

A modern, secure and fast web application, built by experienced developers on a proven stack.

04

Data migration

Migration of your Excel data or your previous tool, without loss and without business interruption.

05

Automation

What used to be re-entered by hand becomes automatic: imports, calculations, reminders, exports and reports.

06

Continuous evolution

Your application grows with you: new features, new roles, new integrations.

ODD Pharma used to process each file in 1 hour on its previous tool. Since PeakLab rebuilt its business application, a file takes 15 minutes and the same team handles 10 times more pharmacies. This is the level of result we aim for on every business application project.
