Summary
EuroBrokers needed a way for users to calculate customs charges on their site.
2410 built a custom WordPress calculator using Excel formulas and live ECB exchange rates.
Increased traffic, better leads, and user engagement within the first month.
Client story
EuroBrokers specializes in customs clearance for goods, vehicles, and parcels across Latvia. They needed a specialized online calculator to help users estimate the cost of customs services quickly and independently.
Their goal was to attract more qualified leads and reduce staff workload caused by unfiltered inquiries. Rather than relying on third-party tools that couldn’t meet their unique needs - such as syncing with real-time exchange rates - they approached 2410 for a fully custom solution.
The result helped engage clients, streamline communications, and bring in real leads from the start.
Project overview
2410 developed a tailor-made online calculator for EuroBrokers to automate the estimation of customs duties, VAT, and total charges based on user input. Built using the company’s own Excel-based formulas, the calculator integrates real-time exchange rates via the European Central Bank's XML feed and updates automatically each day.
To ensure maximum flexibility and brand consistency, 2410 created the calculator as a widget embedded directly into EuroBrokers’ WordPress backend using shortcode integration. This solution bypassed the limitations of third-party platforms, allowing seamless adaptation to the site's design and offering a white-label, performance-optimized tool.
The result is an interactive, multilingual calculator that enhances user experience, filters high-intent visitors, and reduces unnecessary workload for staff. Keywords like "customs clearance calculator," "VAT calculator Latvia," and "import duty estimation tool" are naturally incorporated into the platform, improving SEO and drawing in targeted organic traffic.

Increased Engagement & Better Leads
Immediately after publishing the calculator, EuroBrokers noticed:
- Higher user engagement on the website
- Increased organic search traffic for keywords like "calculate customs duty Latvia", "Latvia VAT calculator online", and "import tax estimation tool"

Tip: By answering “How much does this service cost?” instantly, the calculator works as a pre-qualified lead form.
Technical Accuracy & Real-Time Rates
One of the core features behind this success is the integration with European Central Bank's live XML feed, which updates exchange rates automatically and powers accurate real-time calculations.

Thinking about building a similar system?
These questions are based on what clients typically ask when considering development of a custom business calculator, especially when they need live data integration, a white-label approach, or WordPress compatibility. If you’re planning to build a tailored system for your services, this is for you.
Absolutely. Just like in the EuroBrokers project, we can base the entire solution on your existing Excel files or manual processes. We’ll review the logic, validate the calculations, and convert them into a functional, accurate system that runs smoothly on your site.
Yes. We build the calculator as a fully responsive widget or plugin, styled to fit seamlessly into your site’s look and feel. Whether you're using a custom CMS or WordPress, we make sure the user experience stays visually consistent.
Definitely. We develop with localization in mind. Your calculator can display in as many languages as you need, switching based on user preferences or site settings. Labels and messages are fully editable and translatable.
We can integrate your calculator with reliable external data sources via APIs or XML feeds - just like we did with the European Central Bank for currency rates. This keeps your tool accurate and up to date automatically.
Yes. Mobile responsiveness is standard. We test and optimize the calculator for all screen sizes, so your users can easily calculate and convert whether they're on a desktop, tablet, or phone.
While this example focuses on customs clearance, the same logic applies across industries. If your business involves client estimates, price breakdowns, or service configurators - we can build a similar tool tailored to your needs.
If your site is on WordPress, we’ll deliver it as a shortcode plugin you can place anywhere - pages, posts, or widgets. For other platforms, we can embed it as a standalone script or iframe. We’ll guide you through the integration.
