Stop overpaying for shipping labels.

ShipZen operates under a direct enterprise-level UPS Ground agreement. We consolidate shipments into predictable, high-frequency lanes so UPS can plan trucks and routes around our volume. We also validate every address before printing, which eliminates correction fees. This combination of lane optimization, clean data, and committed volume qualifies us for enterprise pricing that aggregator platforms simply cannot access.

Aggregators pool thousands of unrelated sellers onto a shared account. The result is “noisy” volume — random origins, random destinations, no repeat patterns. UPS can’t optimize routes around that, so the pricing reflects the uncertainty. ShipZen is the opposite: dedicated UPS commitment, predictable lanes, and validated data — which unlocks enterprise-tier pricing.

3PLs handle fragmented volume from thousands of businesses with different packaging, destinations, and timing. They’re also structured for multi-carrier flexibility — optimizing across UPS, FedEx, and USPS simultaneously — so no single carrier relationship is deep enough for enterprise pricing. ShipZen focuses exclusively on UPS Ground with lane-optimized routes.

Enterprise pricing tiers require predictable volume, consistent Ground usage, and repeat lanes. Aggregators can’t provide that because their volume is inherently unpredictable. 3PLs can’t either because their business model is built around variety and multi-carrier flexibility. ShipZen is structured around the exact behaviors UPS incentivizes.

ShipZen offers UPS Ground service across the lower 48 states with flat-rate pricing. Our intentional focus on a single carrier and service is what allows us to offer enterprise-tier rates.

Our flat-rate pricing applies to standard UPS Ground-eligible shipments across a broad weight range — not just lighter packages. Pricing is organized into weight-based tiers, so your rate is determined by which tier your package falls into, not by the specific destination ZIP code within the lower 48 states.

This means you get the same predictable, flat rate whether you’re shipping to California or Connecticut — and the savings compared to platforms like Pirate Ship, EasyShip, or ShipStation apply across weight classes, not just for small, light packages.

Note: Shipments to Alaska, Hawaii, U.S. territories, PO Boxes, and certain remote ZIP codes fall outside our standard flat-rate structure.

No monthly fees, no volume commitments, no minimums. You pay per label, that’s it. Cancel anytime.

None. Our flat-rate pricing is possible because lane optimization averages out distance costs across our network, and address validation removes the hidden fees and risk premiums that make flat rates too risky for aggregator platforms.
