Where the Gaps Appear
What ShipWorks wasn't built for
ShipWorks works well inside its designed use case. These are the moments when it doesn't.
Reliability Risk
On-premises architecture creates fragility
Your shipping speed is constrained by local hardware, Windows update cycles, and on-site IT. A server issue during Q4 peak isn't a cloud ticket — it's a warehouse stoppage.
Cost Intelligence Risk
No AI carrier intelligence
The Best Rate Tool shows you rates. That's not the same as intelligently selecting the right carrier based on performance history, reliability, and real-time cost trends.
Cost Risk
Fixed costs that don't flex with volume
Ship 100 orders or 50,000 — the bill is the same. Fixed subscription tiers mean you're paying for capacity you may not use, or hitting a ceiling when you need to grow.
Reliability Risk
No published uptime SLA
When you depend on a platform to get orders out, you need to know what you're guaranteed. ShipWorks does not publish an uptime SLA. EasyPost commits to 99.99% — in writing.
Real-World Impact
When the platform choice actually matters
The differences aren't visible at 200 shipments a month. They become very visible at 20,000.
01
A DTC brand hits 15,000 shipments/month and rates spike
ShipWorks
The Best Rate Tool surfaces lower rates — but switching carriers requires manual reconfiguration through the UI. Support is unavailable on Sunday when it's discovered. They absorb the cost.
Result: Higher costs. Manual fix under pressure. No Sunday support.EasyPost
Luma AI flags the increase and identifies a regional carrier as cheaper for Zone 4–7. They shift 30% of volume within the week — no new integration, no engineering sprint.
Result: Costs normalized within days. Carrier mix permanently improved.02
A 3PL needs per-client carrier optimization
ShipWorks
Multi-location setups are available in Warehouse plans, but per-client AI optimization doesn't exist. Each client is managed manually. No white-label capability.
Result: Manual overhead per client. No differentiated service offering.EasyPost
EasyPost Forge supports white-labeled multi-client shipping natively. Each client gets its own carrier mix and Luma AI recommendations — no custom build required.
Result: AI-powered shipping as a competitive differentiator for clients.03
An ecommerce brand expands internationally
ShipWorks
International carrier options are very limited. Customs workflows require manual processing outside the platform. A second system is needed for global operations.
Result: Two systems to manage. Fragmented from day one.EasyPost
International carriers activate through the same integration already handling domestic. Address validation, customs, and international rate comparison run on one platform.
Result: International expansion in days, not months.An Honest Look
Where ShipWorks is genuinely the right call
ShipWorks has real strengths. Here's where it's the better choice.
ShipWorks is the right call — if you…
- Run scan-to-ship warehouse teams — native scan-to-ship and batch printing built for non-technical warehouse operators
- Work on Windows-based infrastructure — on-premises software for operations that prefer locally installed tools
- Manage multi-marketplace orders — 70+ channel integrations including Amazon, Walmart, eBay, Shopify Plus and Magento
- Have no engineering resources — GUI-only setup that works without a development team to implement it
What you get with EasyPost instead
- Every carrier ShipWorks connects to, plus 80+ more — with no local install and no Windows dependency
- Luma AI choosing the carrier per shipment instead of a rate table you read yourself
- Pay-per-use pricing that flexes with volume rather than a fixed tier you grow out of
- A published 99.99% uptime SLA and 24/7/365 support, including Sundays and holidays
The honest bottom line: ShipWorks is a good product for a specific kind of operation — warehouse teams that rely on scan-to-ship workflows and batch printing from a UI, operations running on Windows infrastructure, and merchants managing orders across many marketplaces through a single dashboard. The problem isn't ShipWorks. It's staying on it past the point where on-premises architecture and fixed-tier pricing can keep up with your growth.

FAQ
Questions a skeptical buyer actually asks
Can I keep my current carrier accounts if I switch to EasyPost?
Yes. EasyPost supports bring-your-own carrier accounts for all major carriers. You can use your existing negotiated rates or access EasyPost's pre-negotiated Wallet Carrier rates — or both. Nothing you've already built has to go.
Does EasyPost require a developer to set up?
Not necessarily. EasyPost is API-first and built for development teams, but non-technical users can access shipping functionality through EasyPost Forge's embeddable UI. If your team has engineering resources, you'll be live within a day.
ShipWorks advertises 16,000 labels per hour. Can EasyPost match that throughput?
EasyPost is cloud-native and scales automatically without a hardware ceiling. Throughput isn't constrained by a local server or Windows environment — it scales with demand. For high-volume operations, our team can walk you through what that looks like in practice.
What happens to my ShipWorks integrations if I switch?
EasyPost integrates with all major ecommerce channels and marketplaces — including Amazon, Shopify, Walmart, Magento, and others. Most ShipWorks customers find their existing channel connections are supported. Our implementation team handles migration for enterprise accounts.
Is EasyPost more expensive than ShipWorks?
It depends on your volume. ShipWorks charges $189–$799+/month on fixed tiers regardless of how many labels you ship. EasyPost's pay-per-use model means you only pay for what you ship — and Luma AI typically reduces carrier costs significantly, which often offsets the platform cost entirely.
Still running on ShipWorks? You're leaving carriers on the table.
EasyPost gives you every carrier ShipWorks connects to — plus 80+ more, AI-powered rate selection, and the cloud infrastructure to grow without rebuilding.
