USA-based warehouse
All inventory stored and shipped from a central US location. Faster delivery, lower duties, no overseas surprises.
Why 4D Fulfillment
Built by operators who’ve shipped a million orders
We’ve spent years inside warehouses and on seller dashboards. 4D Fulfillment exists because we know what slow receiving, hidden fees, and brittle systems cost a growing brand — and we built the alternative.

What sets us apart
Six reasons brands choose us
Concrete things you can hold us to from day one.
24-hour receiving SLA
Your inbound inventory is counted, inspected, and shelved within one business day of arrival. You see it live in the dashboard.
Real-time inventory visibility
Stock levels, order status, SKU velocity, and aging reports — all from a single dashboard. API access included.
Transparent per-unit pricing
No setup fees, no monthly minimums, no surprise charges. You pay only for what we handle, exactly what you'd expect.
Same-day cutoff
Orders placed before 2pm CT ship the same day. Tracking syncs back to your storefront automatically.
Operators, not middlemen
Our team has worked inside warehouses and run seller accounts. We answer the phone, and we know what you're dealing with.
How we operate
Our values, in practice
The principles we hold the team to — and how they show up in your account.
Operational excellence
We hold ourselves to higher SLAs than our customers ask for. If something can be done in 4 hours, we won't take 24.
Transparency by default
You see every charge, every status update, every photo of damaged returns. We don't make money in the dark.
Partnership over transaction
We win when you grow. Volume discounts, custom workflows, and SLA upgrades unlock as your business scales.
Trusted by sellers
