Shop the US From Anywhere, Ship It Home as One Parcel
Shopping from a US store while living abroad is a maze. US stores that won't ship to you, cards that get declined, and freight bills that cost more than the goods. We built the platform that clears it. Customers get a real US address, shop at any American store as if they were local, and let the warehouse stack their orders. When they're ready, every box gets repacked into one parcel for a single international fee instead of five.
About the Project
One unified hub for the entire parcel-forwarding journey
We were brought in by an international parcel-forwarding company to build the system. Their entire operation runs on one platform serving overseas shoppers, the global carriers moving the freight, and the warehouse staff handling the physical boxes. Before this, buying from US stores while living abroad meant fragmented tools, rejected cards, and barriers that shut international shoppers out.
Our .NET developers engineered a centralized hub handling shipping-account creation, warehouse management, automated package consolidation, detailed progress tracking, and integrations across a stack of carriers. On top sits a membership portal including Basic, Gold, and Platinum which extends storage windows and trims consolidation fees as customers move up. Every layer was built to stay secure and payment-compliant, because handling strangers' money and parcels across borders leaves no room for loose ends.

We needed a partner who could handle messy third-party integrations. FedEx, DHL, Stamps.com, secure payment processors and still ship something clean. Avidclan delivered. They built a transparent rate calculator that killed hidden fees and a session-recovery system that holds up on shaky international connections. Our customers finally have full control over their packages and timelines.

The Solution
Every barrier between you and US shopping, removed in one platform
Patching one barrier at a time was never going to work. A customer blocked at the card form doesn't care how elegant the shipping calculator is. The only fix was to pull every essential function into one secure application and make the pieces work together: a US address, assisted buying, consolidation, transparent pricing, tax savings, and storage that respects the customer's pace. Everything got measured against three things: transparency, security, and global access - and nothing shipped that failed them.
Architecture & Technology Stack Vision
A .NET backbone tuned for high-volume, high-stakes shipping
A platform this size lives or dies on its backend, so we built on Microsoft .NET in C# - the enterprise standard for logistics, and not for fashion reasons. Strict type safety and a compiled core kill off whole families of runtime bugs that quietly wreck dynamically typed shipping systems, exactly where you can least afford them: someone's money and someone's parcel.
Inside the .NET codebase we carved out discrete services - conceptually micro-services within the structure - for the rate calculator, the warehouse dashboard, and the customs engine, so each part stays clean and modular instead of knotting together. Every API endpoint got real authorization policies, and a custom session-management layer authenticates international users so each one only ever reaches their own suite and consolidated packages.
The frontend runs on ASP.NET Web Forms (ASPX). It's older tech - we know how that reads - but the team tuned the page lifecycles until the heavy, data-dense dashboards loaded fast, with no jarring lag for a customer juggling consolidations across several shipping zones. Data sits in a hard-tuned SQL Server database, the platform runs on IIS, and a persistent custom session login means a user on a flaky international connection doesn't lose their place when the signal drops.
Tools & Technologies
The complete engineering toolkit
Development Process
Four months, two-week sprints, a team of five
Five specialists shipped this in four months on strict two-week Agile sprints, coordinating over Gmail and WhatsApp, leaning on Claude and ChatGPT for the grunt work, locking every commit behind peer review in GitHub, and securing access with a persistent custom session login.
Strict Security & Compliances
Built to clear the strictest shipping and payment rules
In cross-border shipping, a compliance miss isn't a fine; it's a parcel frozen at a port and a customer who doesn't come back. We treated data security and trade compliance as law, not preference, and built the platform to clear the toughest bars.
Electronic Export Information (EEI) Filing
For high-value shipments - generally over $2,500 per commodity, or anything needing an export license - we wired automated EEI filing into the Automated Export System (AES). The C# backend reads each consolidated package's declared value and destination, and when US customs law requires a filing, the platform flags the order, walks the user through submission, and transmits the declaration securely. No manual paperwork, no surprise port delays, no compliance gaps.
PCI-DSS (Payment Card Industry Data Security Standard)
Moving international card payments leaves no margin for error. By integrating PayPal and Authorize.Net through secure tokenization, we kept raw cardholder data off our own servers entirely. Subscriptions and dynamic shipping fees process cleanly, while the heavy cardholder-security burden sits with fully PCI-compliant gateway partners - exactly where it belongs.
International Trade Compliance
The platform polices borders on its own. The C# backend checks destination zip codes against known embargo and restriction lists before anything ships, keeping the company square with global trade law, and the automated customs generator guarantees every parcel crossing a border carries accurate, legally binding data instead of a best guess.
Project Outcome & Long-term Impact
A platform that turned a fragmented headache into one clean workflow
Picture the old way. A shopper in São Paulo wants five things from five different US stores. Two sites won't ship abroad. One rejects the card. The three that go through each charge full international freight, plus US sales tax, plus fees that only surface at checkout. The order falls apart before it ships.
