What our clients say
The insights were clear, concrete and directly actionable. On Facebook in particular, their work helped us identify key levers and more than triple our CTR.
Martin CharousseteCommerce Manager, SodaStreamWe feel listened to, challenged and supported like a true extension of the team. Their strength is also their overall eCommerce vision, which brings far more value than media management alone.

What you want to know before starting.
The questions we hear most often. We answer them here, before you even ask.
What does an eCommerce agency like OMOSA do?
We run online growth for fashion and lifestyle brands across three areas: acquisition (Meta, Google, TikTok, Pinterest), the site (Shopify, conversion) and retention (Klaviyo, email, SMS). One senior team, one roadmap, and decisions that start from your margin.
Can we work on a single area?
Yes. We take on one or several areas: paid media, eCommerce, CRM. We work with the agencies and freelancers you already have: we keep those who perform, and we tell you when they do not. We are simply more effective when we hold all three areas: each one feeds the other two.
How does a collaboration start?
With a first look at your figures, free of charge. A 30-minute call to get to know you and set up access, a few days of analysis, then a 30-minute debrief: a document you keep, and five actions for the next 30 days. No commitment. If you want to go further, the full audit takes weeks 1 and 2, and the launch happens in weeks 3 and 4.
How much does it cost?
Each offer is a fixed monthly fee, with no variable part. Attract, paid media: from €2,500 per month. Activate, eCommerce: from €3,350 per month. Retain, CRM: from €3,350 per month. The audit of the three areas: from €3,000, once.
What is the minimum commitment?
Three months, renewable by quarter, with 30 days’ notice. Three months is one full steering cycle: long enough to measure, short enough to correct.
How do you measure results?
With one scorecard shared by the three areas: acquisition cost, blended COS, conversion rate, average order value, repeat rate, LTV. A call every two weeks, a report every month. Every decision starts from your margin, not from the performance of a platform.
Which brands do you work for?
Fashion and lifestyle brands. Our goal: take your brand from €1M to €5M in eCommerce revenue, while staying profitable. We have supported 50 brands since 2024: you benefit from what we have learned with brands like yours.
Who works on our account?
Specialised senior consultants: there are 6 of them, with 7 years of experience on average, from brands such as Jérôme Dreyfuss, L:A Bruket, Printemps or Faguo. You meet the team that will work on your account before you sign.
What do we need to bring?
We accelerate what exists; we do not replace what is missing. You need a product range that keeps evolving, a steady flow of content, and real involvement on your side: quick decisions and trust. Acquisition, conversion and retention do part of the work. Product, brand and content do the rest.
Your audit starts here.
The call
30 minutes to understand your business.
The analysis
Within a few days, we cross-check your platforms: what they report, and what you actually earn.
The debrief
30 minutes and a document you keep: what we saw, and five actions for the next 30 days. No commitment.
