Superportage is the only HR partner in France working exclusively with portage salarial companies. They handle payroll, compliance, and back office administration under their clients' own brand. The service is genuinely complex and the buyer is a company director who needs to understand the commercial case before anything else.

problem

Two things made this harder than a standard service site. The offer splits into three distinct products, each with a different buyer and a different objection, so a single services page was never going to hold all of it. Each one needed room to make its own case.

The bigger problem was financial. The real question every prospect has is whether outsourcing the back office actually makes them more money, and until then that answer lived in a spreadsheet the founders walked people through on calls. The site could describe the service, but it could not close anyone on its own.

solution

The core of the build is a live margin simulator. Five inputs (number of active consultants, average day rate, working days per year, management fee, optional factoring) feed a real time calculation of total managed revenue, gross margin, factoring cost, total annual charges, and estimated net margin. It runs entirely in the browser with no page reload, so a director can model their own business in about thirty seconds and see the number that actually matters to them.

Everything around it is built to support that moment. The three offers each get their own page with room for their own proof, while the homepage carries just enough of each to route people correctly. The problem section uses real quotes about the daily reality of the job (payroll firms that do not understand financial reserves, expense rules nobody can pin down, URSSAF inspection risk) so visitors recognise their own situation before they see the solution.

A CMS driven blog and a glossary handle the long tail of search around a niche where nobody has published anything useful, and the whole site runs in French with the terminology the industry actually uses.

outcome

Superportage now has a site that does the commercial conversation on its own. A director can arrive cold, model their own margin, understand which of the three offers fits, and book a call already convinced of the numbers. The work that used to require a spreadsheet and a phone call now happens before anyone gets in touch.
