How it works
What happens after kickoff.
Take your rates to market
We take your last 90 days and put your lanes out to the full carrier network, benchmarked against our rate database.
Present the recommendation
About two weeks in, you get a clear read: where your rates sit, what's recoverable, and exactly what we'd change.
Onboard the program
You keep your contracts. We stand up the new carrier program and tune it, no third-party billing layer in the middle.
Recover, month over month
Invoice errors caught, SLAs enforced, claims filed. No invoice error or SLA left unclaimed, in your Slack.

What to expect
Questions before you start
Is my brand a fit for Iron Margin?
If you're a DTC brand shipping parcels, talk to us. We run a free evaluation for every brand: we benchmark your last 90 days against our carrier database and show you the savings that are actually there. You make an informed decision from real numbers, not a sales pitch, and there's no commitment to find out.
What data do you need to get started?
An export of your last 90 days of shipping. Each row needs at minimum: origin zip, destination zip, weight, dimensions, carrier, service type, and cost. Format varies by WMS (ShipStation, EasyPost, Shopify, Shiphero, Extensiv exports all work). We'll guide you through the export on the intro call.
How long does it take to see results?
About 2 weeks from kickoff to a benchmarked recommendation, and typically 4 to 6 weeks to fully live. We've moved faster than that, but the timeline depends on the complexity of the project and how quickly we can get what we need from your side. Carrier setup and integration are the long pole, not the analysis. From there we onboard the new carrier and review the first invoices, with the rest of the work running alongside.
How much lift is onboarding for my team?
Light. We need one export of your last 90 days to start, usually a few clicks in your platform, plus a short call to confirm box sizes and weights. No engineering or integration project on your end.
Do you have to switch carriers?
No. We negotiate better rates with your existing carriers first. If a new carrier offers meaningfully better pricing, we'll flag it, but you always decide.
Who owns the carrier contracts?
You do. We negotiate on your behalf, but the contracts are between you and the carrier. No Iron Margin in the middle, no third-party billing layer.
What happens after the free evaluation?
You receive a written comparison of your recent shipping rates and the opportunity we found. If the numbers justify more work, we show you the recommended next step and its scope before any paid engagement begins. You decide whether to continue.
