Ecommerce Fulfillment

Ecommerce Fulfillment Solutions

Selling online is hard enough without wondering where your orders are, whether they’ll ship on time, or how much you’re overpaying to get them out the door. PSI gives high-volume D2C brands the technology, accuracy, and hands-on support of a much larger operation, without losing the personal relationship. You send us your inventory; we pick, pack, ship, and keep your customers coming back.

SCOPE OF SERVICES

Our ecommerce fulfillment services cover everything that happens after a customer clicks “buy.” From the moment your inventory arrives at our warehouse to the moment tracking lands in your customer’s inbox, PSI handles the details so you can focus on growing your brand. Every order is second-person verified, and anything received by 1 PM EST ships the same day.



Integrated Order Management

We connect directly to your online store for hands-free order transmission. Orders flow straight into our warehouse management system the moment they’re placed, and tracking flows right back to your customer, no spreadsheets, no manual uploads, no missed shipments.



Accurate Pick, Pack & Ship

Order accuracy is a big deal, which is why every order we fulfill is second-person verified. Always. We maintain 99.98+% order accuracy across all orders shipped, and orders received by 1 PM EST go out the same day, so your customers get fast, reliable delivery every time.



Storage, Inventory & Returns

We store your products safely, maintain accurate inventory counts you can trust, and manage returns through our dedicated returns processing center – helping you reclaim revenue and keep customers happy.

OUR PROCESS

We make outsourcing your ecommerce order fulfillment as easy as connect, store, and ship.

SHIP

Your customer places an online order and we fulfill and ship it.

Ecommerce Platforms & Marketplaces We Integrate With

PSI’s warehouse management system connects directly to hundreds of ecommerce platforms and marketplaces through hands-free API integrations, including Shopify, Walmart, and Amazon. Orders flow downstream into our system, where they’re batched for our pickers, checked for accuracy, packed to your specifications, and shipped. Tracking then flows back upstream to your store and alerts your customer that the package is on the way. Our automated rate-shopping technology compares carriers on every package by weight, dimensions, and destination, so each order ships the best available way.
