Batch Shipping & Subscription Fulfillment
Subscription & Batch Fulfillment Solutions
Recurring orders should be the easy part of your business, not a monthly scramble. As a familyowned 3PL that has been fulfilling orders since 1986, PSI handles subscription box fulfillment and batch shipping so every subscriber gets the right box, on schedule, at the best possible shipping cost. You focus on curating your product and growing your list. We handle the kitting, packing, and shipping behind the scenes.
SCOPE OF SERVICES
Whether you send hundreds of subscription boxes a week or run periodic batch mailings, PSI manages the full process from our secure Atlanta warehouse. Every order is second-person verified for accuracy, and orders received by 1 PM EST ship the same day.
Recurring Subscription Fulfillment
We store, kit, pack, and ship your recurring subscription orders on schedule, cycle after cycle. As your subscriber count grows from a few hundred boxes to many thousands, we scale with you without missing a shipment.
Batch Shipping and Rate Shopping
For groups of orders that share the same items, packaging, and weight, we process and rate shop in batches rather than one order at a time. That keeps your fulfillment costs lower and your orders moving faster, while our technology still selects the best-cost carrier for every individual package.
Kitting, Custom Packaging, and Inventory
Great subscription boxes are all about the unboxing. Our kitting and assembly team curates and assembles your boxes, adds inserts and branded packaging, and keeps accurate counts across every SKU so you never run short mid-cycle.
OUR PROCESS
We make subscription and batch fulfillment as easy as connect, store, and ship.
CONNECT
We integrate to your website for hands-free order transmission.
STORE
You send us your inventory for us to store safely in our warehouse.
SHIP
Your subscribers’ orders are kitted, packed, and shipped on schedule, every cycle.
Ecommerce and Subscription Platforms 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, along with the subscription and billing tools your store already runs on. Orders flow downstream into our system, get batched for our pickers, checked for accuracy, packed to your specifications, and shipped, while tracking flows back upstream to keep your subscribers informed. See our full list of Partners and Integrations.
When Does Batch Fulfillment Make Sense?
Batch fulfillment is ideal for any group of orders with an identical set of items, packaging, and weight. Common examples include ecommerce subscriptions, periodic or seasonal mailings, large one-time mailings, and custom kitting projects. Here is how it looks in action at PSI:
- Weekly subscription orders for a national vitamin and supplement brand. We fulfill and ship hundreds of subscription orders every week, arriving on schedule with the bestcost ship method applied to each shipment.
- Custom graduation kits for a public university. We kit and shrink-wrap custom boxes with diplomas and personalized items, then ship them nationwide with expedited service so they arrive on the same day across locations.
- Quarterly marketing kits for a local business. We kit and ship thousands of marketing folders with variable data as part of a recurring quarterly campaign.
