A technology distributor in the Lisbon area managed a catalogue of over 6,000 references — from network components to office equipment — through PDF files sent by email. Purchase prices changed daily with currency fluctuations and supplier adjustments, but the catalogue was updated only twice a month. The result: manually calculated margins that sometimes turned negative without anyone noticing, and sales representatives selling products already out of stock at the supplier. The implementation of a B2B e-commerce platform with automated supplier synchronisation and real-time margin calculation transformed the operation and increased revenue by 28% in the first year.
The Scenario Before: Static Catalogues in a Dynamic Market
TechDistrib (real case — data altered under NDA) distributes IT, telecommunications and audiovisual equipment to resellers, systems integrators and corporate IT departments across the country. With 18 employees and a network of over 400 active clients, the company generated annual revenue of €5.4 million and worked with 14 international suppliers.
The product catalogue was the central business tool — and it was a 280-page PDF file. A designer spent two days per month updating it with prices, new references and discontinued products. The file was then sent by email to all clients. Sales representatives printed copies for in-person visits.
The problems inherent to this model were multiple and deep:
Outdated prices. In the technology sector, purchase prices can change daily — currency fluctuations (many suppliers quote in dollars), temporary manufacturer promotions, seasonal adjustments. A fortnightly updated catalogue meant that, on average, 22% of listed prices no longer corresponded to the actual cost at the time of sale.
Manual margin calculation. Each sales representative had an Excel spreadsheet where they calculated the margin per product based on the most recent purchase price they knew (not always the current one). Margin rules varied by product category, by client and by volume — and they were in the sales representatives' heads, not in a system. Negative-margin sales occurred on average 3 to 4 times per month.
Unknown stock. The catalogue did not reflect real availability. A client would order a network switch listed in the PDF that had already been out of stock at the supplier for two weeks. The sales representative only discovered this when trying to place the order with the supplier. This generated delays, frustration and loss of credibility.
Slow ordering process. The client viewed the catalogue, called or emailed the sales representative, who checked price and availability, prepared a quote in Word, sent it by email, waited for approval, placed the order with the supplier and recorded everything in the ERP. The average time from client request to order confirmation was 4.2 hours.
Diagnostic in Numbers
• Outdated prices in the catalogue: 22% of references at any given time.
• Negative-margin sales: 3–4 per month, average loss of €180 per incident.
• Orders cancelled due to unavailability: 14% of total.
• Average order processing time: 4.2 hours.
• Weekly hours spent on catalogue updates: 16 hours (designer + sales team).
• Error rate in quotes: 9.3% (wrong price, mixed-up reference, incorrect terms).
• Estimated cost of the manual model: €87,000/year (lost time, negative margins, lost clients).
The Solution: B2B E-Commerce with Margin Intelligence
Component 1: B2B Platform with Dynamic Catalogue
We developed a B2B online store where each client accesses with their own credentials and sees a personalised catalogue: the products available for their segment, with the negotiated prices for their profile, filtered by category, brand, compatibility and real availability. The catalogue is searchable, with technical data sheets, product images and integrated manufacturer documentation.
The key difference from the static PDF is that the catalogue is alive. Prices update automatically several times a day, availability reflects real stock (from the company's own warehouse and from suppliers), and new products appear as soon as they are configured — without waiting for the next update cycle.
The client can order directly, check the status of previous orders, download invoices and manage their data — all without needing to call or send an email. For recurring purchases, we created a "favourites list" and "quick order" feature, where the client pastes a list of references and quantities and the system automatically prepares the basket.
Still distributing technology with PDF catalogues and manual quotes?
We build B2B online stores that automatically synchronise with suppliers and calculate margins in real time.

This was the most technically challenging component and the one that generates the most value. We integrated the B2B platform with the systems of TechDistrib's 14 suppliers. Each supplier makes data available in different ways — some via API, others via EDI files, others via XML feeds, and two still via CSV files exported from their system.
We created specific connectors for each supplier that automatically import: product catalogue (references, descriptions, technical data sheets), updated purchase prices (with automatic currency conversion for suppliers quoting in USD or GBP), real-time stock availability, estimated delivery times, and temporary promotions or special conditions.
Synchronisation occurs at different frequencies depending on the supplier: every 15 minutes for the largest, hourly for the remainder. A dashboard shows the status of each integration, with automated alerts when a synchronisation fails or when data anomalies are detected (for example, a price that changes by more than 30% from one day to the next).
Component 3: Automated Margin Engine
The third component is the margin calculation engine, which applies sophisticated business rules automatically and in real time. The rules include: minimum margin by product category (for example, 8% on networking, 12% on audiovisual, 5% on consumables), volume-adjusted margin (tiered discounts for orders above certain values), per-client margin (premium clients with special conditions), and absolute minimum margin (never below a set euro value per unit).
The system automatically recalculates the selling price whenever the purchase price changes. If a supplier increases the price of a network switch from €145 to €152, the selling price for each client segment is adjusted instantly, respecting the defined margin rules. No sales representative needs to intervene — and no sale is made below the defined minimum margin.
A real-time margin dashboard allows the commercial leadership to monitor average margin by category, by client and by sales representative, identify trends and make informed pricing decisions.
Results After 12 Months: Before vs. After
The results after the first full year of operation are clear:
• Outdated prices: from 22% to 0.4% (occasional synchronisation delays).
• Negative-margin sales: from 3–4/month to zero (blocked by the system).
• Orders cancelled due to unavailability: from 14% to 2.1%.
• Average order processing time: from 4.2 hours to 12 minutes.
• Weekly hours on catalogue management: from 16 to 2 (curation and highlighting new arrivals only).
• Average margin per sale: 1.8 percentage point increase (result of eliminating negative-margin sales and automated optimisation).
• Total revenue: from €5.4M to €6.9M (+28%), driven by ease of ordering and after-hours orders.
• New clients: 47 new resellers registered on the platform in the first year.
Return on Investment
The total project investment — B2B platform, supplier connectors, margin engine, ERP integration, training and data migration — was €41,000. Direct savings (elimination of negative margins, reduction of manual work hours, reduction of cancellations) stand at €68,000 annually. Incremental revenue generated by the platform exceeds €1.5 million. Payback was achieved in less than 8 weeks.
Conclusion
Technology distribution is a business of speed and precision. Static catalogues, manual pricing and slow ordering processes are incompatible with a market where prices and availability change by the minute. TechDistrib proved that the transition to a digital B2B model is not merely possible — it is the difference between growing 28% and continuing to lose margin without understanding why.
If your product catalogue is still a PDF and your sales representatives calculate margins in Excel spreadsheets, the opportunity cost is real and grows with every passing day.
