Do you sell to businesses? Why you need an ecommerce consultancy specializing in B2B

Your B2B ecommerce does not fail by design, it fails because it tries to sell as if it were a consumer store. A specialized consultancy doesn't just improve the look and feel: it analyzes your processes, identifies bottlenecks and builds a digital system that responds to how businesses really buy. If your customers prefer to call rather than buy online, you don't need more traffic: you need a B2B strategy that converts.

Marketing Agency: 72% of Companies Dissatisfied by Broken Expectations

72% of companies report dissatisfaction with their marketing agency. Not for lack of talent in the industry. It's because of a brutal misalignment between expectations and reality. Agencies promise "exponential growth" and deliver pretty reports with metrics that don't pay the bills. This guide cuts through the noise: what to look for in a marketing agency that generates measurable ROI (not likes), how much it really costs (from €2,000/month boutique to €15,000/month full-service with hidden pricing traps), what results to expect depending on budget and company stage (startup vs scale-up vs enterprise have radically different needs), and the 8 red flags that scream "this agency will bleed you dry without results". Includes 6 real case studies companies 5K€-50K€/month budget showing what worked vs. what failed with numbers without makeup, the exact framework to audit if your current agency works or sleeps, and when you DON'T need agency (40% companies spending on agencies should be in-house or with freelancers). No corporate motivation. No "end-to-end solutions". Only what works and what burns money.

Google Advertising Agency: 67% of Budget Is Wasted Due to Mismanagement

67% of the budget invested in Google Ads is wasted on clicks that never convert. Not because Google doesn't work. Because most agencies manage campaigns as if it were 2010. This guide cuts through the noise: what to look for in a Google ad agency that generates real ROI (not vanity metrics), how much it really costs (from 800€/month management + ad spend up to 5,000€/month depending on complexity), what results to expect (typical ROAS 3-6x if done right, 0.8-1.5x if done wrong), and the 7 red flags that scream "this agency is going to burn your budget". It includes 5 real cases with no make-up numbers: exact investment, measured ROAS, and what worked or failed. We document how to place an ad on Google correctly (not just "create campaign" but structure that converts), real Google Ads prices by industry (CPC from 0.80€ to 25€ depending on the sector), and why YouTube Ads can be your best channel or your worst mistake depending on your business model.

This guide cuts through the noise: what to look for in an AI company that really works, how much it costs (spoiler: between 5,000€ and 150,000€ depending on the project), what results to expect (automation 40-80% repetitive tasks first 6 months), and the 8 questions you should ask before signing a contract. It includes 6 real cases with measured ROI, the 5 red flags that indicate that an AI consulting firm is selling you vaporware, and the exact framework to evaluate if your company is ready for AI or if you need to fix basic processes first. No empty motivation. No corporatism. Just what works and what doesn't.
