Do you bill short client calls? I'm looking for 5 pilot users

I'm looking for five independent consultants or IT service providers who bill some client calls or short interventions by time spent, or through prepaid hour packages.

I built GestTemps, a mobile app that captures this billable time and assigns it to the right client. What I need now is feedback from people who have used it for a while on real work. A reaction to a demo doesn't tell me much.

The pilot program:

  • 14 days of real use
  • at least three real calls or interventions recorded
  • a five-minute questionnaire at the end
  • an optional 15-minute conversation

Participants who complete it get one year of GestTemps Premium for free.

I'm asking for honest feedback, criticism included. Reviews and ratings are no use to me here.

If this matches how you work, comment or send me a message with your profession, whether you bill client calls or short interventions, and whether you are on Android or iPhone.

    The real test seems to be whether repeated use changes what actually gets billed. After a few weeks, do users discover previously missed billable time, or does GestTemps mainly make recording time they already captured a little easier?

      GestTemps truly helps recover lost revenue and goes beyond simply making time entry easier. In just 3 clicks, users can log their work, including those small tasks that are often forgotten or left unbilled.

      By catching this previously lost time, GestTemps directly increases billable hours and boosts your income. On top of that, the solution provides precise dashboards detailing the tasks completed and services provided, making it easier to track your activity, justify invoices, and identify your most profitable services.

        That’s the key test. I’d be interested in seeing what the post-launch data shows. If you’re open to it, what’s the best email to reach you on?

          I invite you to try out the software yourself by downloading it from the app stores (Android or Apple). Simply search for "GestTemps".

            I’d be happy to take a look. I only use email for this — if you’re open to it, what’s the best email to reach you on?
