Our B2B e-commerce expertise

Synolia is an agency specializing in B2B e-commerce consulting and implementation. Our mission? To orchestrate the complexity of your digital ecosystem and drive your performance through profitability.

B2B e-commerce: precision that drives profitability

B2B leaves no room for guesswork. Unlike B2C strategies, which are often driven by marketing ROI metrics, a successful business-to-business e-commerce project demands rigorous control of your business processes and a single goal: making sure your digital investments are truly profitable.

Why is Synolia one of the best B2B e-commerce agencies in France?

Looking for the best partners to deliver a large-scale B2B e-commerce platform? Synolia stands out as a leading agency in the French market thanks to four core pillars:

Mastery of technical and functional complexity:
Custom price lists, multi-faceted catalogs, tailored purchase flows (approval workflows, credit limits, quotes)… We master the complex rules of B2B commerce.
Integration at the heart of your ecosystem (ERP, CRM, PIM):
A B2B site is not an island. Our teams natively connect your platform to your critical tools (ERPs such as SAP, Microsoft Dynamics and Sage, PIM/DAM product information tools, OMS) for real-time synchronization of inventory, prices and orders.
A multi-site, international approach:
Whether you manage several brands or subsidiaries or are expanding internationally, we design robust, centralized architectures that handle high volumes and comply with local regulations.
A pragmatic approach to AI that drives efficiency:
Artificial intelligence is not a marketing gimmick but a real lever for operational performance. We put it to concrete use on targeted business use cases: automated generation and enrichment of product pages, intelligent search and recommendation engines, and optimized visual search and customer support.

Our vision for 2026

Stop worshipping revenue: aim for profit!

It’s time to say out loud what many merchants hide behind flattering growth curves: revenue has become a hard drug, and the detox is going to hurt. For too long, the e-commerce ecosystem has been drunk on volume, market share and “GMV”*, forgetting one basic rule: a company that doesn’t make money is a hobby that ends badly.

In 2026, the illusion is collapsing. With soaring costs and maturing markets, the only question that matters is no longer “how much did you sell?” but “how much did you actually keep?”

The cost structure audit

Synolia offers this audit to pinpoint profitability leaks: obsolete catalog segments, complex logistics processes and scattered data.

We reconcile your accounting view and your marketing view to build a healthy, agile and profitable B2B e-commerce platform.

"IT becomes a drag on profitability the moment you keep monolithic systems that are expensive to evolve. In 2026, agility is a matter of economic survival."

Romain André, CEO of Synolia Group
"Technology should serve the process, not the other way around. I see too many companies invest tens of thousands of euros in a “gimmick” feature while their conversion funnel loses 50% of mobile users because of a 2-second delay."

Olivier Bernasson, founder of pecheur.com

Have a B2B e-commerce project?

Our consultants and integrators, based in Lyon, Bordeaux, Paris, Strasbourg, Rennes and Santiago, Chile, support you from strategic scoping to the maintenance of your platform.

How can you improve B2B e-commerce conversion?

To improve B2B e-commerce conversion, the key is to simplify buying by adapting your site to the complexities and critical features of B2B (custom pricing, credit limit management, approval roles). Invest in flawless product findability with a search engine that handles technical part numbers and industry-specific filters, paired with a smooth UX/UI that shows personalized prices, stock levels and quick-order modules in real time (one-click reordering, pay on invoice).

How do you connect your ERP, PIM, CRM and e-commerce platform to gain efficiency?

To maximize operational efficiency, a B2B site can’t run in isolation: its technical architecture must rely on native integration and real-time synchronization of your critical tools. Connecting them means setting up an architecture linked by APIs and native connectors that keep your entire information system talking in real time. In practice, each tool keeps its expert role: the ERP sends inventory and customer-specific prices and processes orders; the PIM/DAM feeds the site with visuals and enriched technical data sheets; and the CRM centralizes customer history. This automatic synchronization guarantees a single, always up-to-date source of data on your site, with no manual data entry.

How do you audit the profitability of a B2B e-commerce business?

Auditing the profitability of a B2B e-commerce business means analyzing the entire value chain, beyond revenue alone. The audit starts by measuring customer acquisition cost (CAC) against customer lifetime value (LTV), along with a detailed analysis of net margins by segment, customer or sales channel. Next, it assesses the operational economies of scale that digital delivers: shorter order processing times, fewer data entry errors and automated customer service. Finally, reviewing infrastructure costs (technical maintenance, ERP/PIM connectors) validates the overall return on investment (ROI) and identifies the top-priority optimization levers.
