Stop Renting Your Logistics Core: Build Your Own EasyPost-like Shipping API

Gain full control, eliminate recurring fees, and create a shipping platform tailored to your exact business needs. Get a fixed-price development blueprint in 48 hours.

For e-commerce businesses and logistics providers, relying on third-party shipping APIs like EasyPost often means accepting a compromise. You get convenience, but at the cost of escalating fees, limited customization, and being locked into someone else's ecosystem. The strategic alternative is to own your shipping infrastructure. By developing a custom platform, you transform a major operational expense into a strategic asset that scales with your business, provides invaluable data insights, and perfectly aligns with your unique workflows.

100% Tailored to Your Workflow

Off-the-shelf solutions force you to adapt your processes to their software. We do the opposite. We design the software around your unique operational needs, from custom business rules and carrier integrations to specialized reporting dashboards.

Seamless ERP & WMS Integration

A shipping platform can't live in a silo. Our experts specialize in complex integrations, ensuring your new API communicates flawlessly with your existing ERP, Warehouse Management, and e-commerce systems (like SAP, Oracle, Shopify, Magento).

Dedicated AI-Enabled PODs

Your project is powered by a dedicated, cross-functional team (a POD) of AI-enabled developers, QAs, and a project manager. This ensures cohesive teamwork, clear communication, and a single point of accountability for success.

Full IP & Source Code Transfer

You own what you pay for, period. Upon project completion and final payment, we transfer 100% of the intellectual property and source code to you. Your platform is your asset, giving you ultimate control and flexibility for the future.

Core Features Your EasyPost Alternative Must Have

We build comprehensive shipping platforms with all the functionality you expect from a market leader, plus the custom features you need to outperform the competition.

Multi-Carrier API Integration

The heart of your platform is a single, unified API that connects to all your carriers. We build robust, well-documented endpoints that simplify the integration process for your developers and partners, eliminating the complexity of managing dozens of different carrier APIs.

  • Connect to global carriers like FedEx, UPS, DHL, USPS, and regional providers.
  • Integrate LTL freight and specialized carriers for a truly unified system.
  • Standardize data formats across all carriers for consistent and easy processing.

Automated Label Generation

Instantly generate carrier-compliant shipping labels in various formats (PDF, ZPL, PNG). Our system ensures all labels meet the specific requirements of each carrier, including barcodes, tracking numbers, and service types, minimizing the risk of costly errors and delays.

  • Support for domestic and international shipping labels.
  • Automated generation of customs documentation (e.g., commercial invoices).
  • Customizable label templates to include your branding or internal reference numbers.

Real-Time Rate Shopping

Empower your team to make cost-effective decisions for every shipment. Your custom API can fetch real-time rates from all connected carriers simultaneously, allowing you to instantly compare costs and delivery times to select the optimal service for any package.

  • Apply custom business rules (e.g., "always choose the cheapest option under 3 days").
  • Factor in your negotiated carrier rates for accurate cost comparison.
  • Display rates clearly in your internal dashboard or at your e-commerce checkout.

Shipment Tracking & Webhooks

Provide proactive, real-time tracking information to your customers and internal teams. We implement a robust tracking system that normalizes status updates from all carriers into a consistent format and uses webhooks to push updates automatically to your other systems.

  • Create a branded tracking page for a seamless customer experience.
  • Configure webhook notifications for key events (in transit, out for delivery, delivered).
  • Centralize all tracking data in a single dashboard for your support team.

Beyond the Basics: Advanced & Custom Features

This is where owning your platform provides a true advantage. We can build advanced features that off-the-shelf solutions can't offer, tailored specifically to your business goals.

  • AI-Powered Route Optimization: Analyze historical data to recommend the most efficient multi-package shipping strategies.
  • Predictive Delivery ETAs: Use machine learning to provide more accurate delivery estimates to customers.
  • Advanced Analytics Dashboard: Visualize your shipping spend, carrier performance, and delivery success rates to identify cost-saving opportunities.

Industry: Retail & E-commerce

Client Overview: A mid-sized online retailer specializing in home goods, shipping over 15,000 packages per month across the US. They were struggling with the high and unpredictable per-label fees from their SaaS shipping provider, which was significantly impacting their profit margins.

Enterprise Unifies Global Supply Chain with Custom API

Industry: Manufacturing

Client Overview: A global manufacturing company with a complex supply chain involving both small parcel shipments from distribution centers and large LTL freight shipments between factories. They were using multiple disparate systems, leading to data silos and inefficiencies.

"CIS successfully tackled a challenge our internal team had struggled with for years: creating a single API for both parcel and freight. The visibility we've gained into our total transportation spend and operations is transformative."

- Carter Fleming, VP of Supply Chain, Global Manufacturing Inc.

Frequently Asked Questions

Have questions? We have answers. Here are some common queries about building a custom shipping platform.

The cost typically ranges from $35,000 for a core MVP to $150,000+ for a feature-rich, enterprise-grade platform. The final price depends on the number of carrier integrations, complexity of business rules, custom UI/UX design, and advanced features like AI-powered analytics. Our interactive calculator can give you a good starting estimate, but a detailed consultation will provide a fixed-price quote.

Using our AI-accelerated process and pre-built modules, a core platform (MVP) can be launched in as little as 10-14 weeks. A more complex build with numerous integrations and custom features may take 5-8 months. We provide a detailed project timeline as part of our initial Solution Blueprint.

While EasyPost is a great tool for startups, businesses with significant volume or unique needs face challenges with it, including: 1) **Cost:** Per-label fees become a major expense at scale. 2) **Control:** You are dependent on their roadmap and can't build custom features. 3) **Ownership:** You are renting a service, not building a strategic asset. A custom platform eliminates these issues and offers a better long-term ROI.

We offer flexible and comprehensive post-launch support and maintenance plans. This can include 24/7 monitoring, bug fixes, security updates, performance optimization, and dedicated support hours for feature enhancements or adding new carrier integrations. We partner with you for the long term to ensure your platform evolves with your business.

Absolutely. Upon final payment, we transfer 100% of the intellectual property, documentation, and source code to you. The platform is your asset, and you have complete freedom to modify, extend, or even sell it in the future. We believe in full transparency and client ownership.
