MORE THAN PICK, PACK & SHIP
Supplement Fulfillment Has Its Own Operational Demands
Fulfillment gets more complicated as a supplement brand adds products, order volume and sales channels.
Inventory may include multiple formulations, sizes and SKUs. Products may be sold individually, bundled together or shipped through recurring subscriptions. Promotions can change what goes into an order, while ecommerce, marketplace and wholesale channels each bring different fulfillment requirements.
Storage conditions matter, too. Product requirements should be reviewed before inventory enters the warehouse to make sure the fulfillment environment is appropriate.
The operation also needs to work beyond where your brand is today. A business that begins primarily with direct-to-consumer orders may later add subscriptions, Amazon, wholesale accounts or larger B2B shipments.
01
Does the warehouse environment fit your product requirements?
02
Can one provider handle both individual consumer orders and larger B2B shipments?
03
Can the operation support bundles, kits, inserts and recurring subscription orders?
04
Will you have visibility into inventory and order activity?
05
Can you reach someone directly when a fulfillment issue needs attention?
06
Can the 3PL support additional sales channels as your business grows?
ONE OPERATION, MULTIPLE SALES CHANNELS
Support for the Different Ways Your Brand Sells
Square1 handles both small-piece D2C orders and larger B2B shipments. That gives growing brands the ability to add sales channels without automatically splitting inventory between multiple fulfillment providers.
Subscription Fulfillment
Square1 supports recurring subscription orders, including programs that require defined packing instructions, inserts, product bundles or kits.
Amazon & Marketplace Fulfillment
Square1 supports Amazon MFN fulfillment and FBA preparation along with marketplace fulfillment.
B2B & Wholesale Fulfillment
Brands can fulfill individual ecommerce orders and larger B2B, wholesale, retail, LTL and FTL shipments through the same 3PL.
Kitting & Bundles
Physical and virtual kitting can support multi-product bundles, promotional kits and other defined product configurations as part of the broader fulfillment program.
CONSISTENT CONDITIONS MATTER
Controlled Storage From Our Missouri Warehouse
Square1 operates from Springfield Underground in Springfield, Missouri, where our warehouse environment is maintained at 64–69°F and 30–50% humidity.
For supplement and nutraceutical brands, storage requirements should be reviewed before inventory is moved into a fulfillment facility. We can compare your product requirements with our warehouse conditions to determine whether the environment is appropriate for your inventory.
Our Springfield location also provides a central U.S. fulfillment point for brands distributing across the country. Supplement inventory can be positioned in Missouri while supporting ecommerce customers, marketplaces and business accounts throughout the United States.
STAY CONNECTED TO THE OPERATION
See Your Inventory. Follow Your Orders. Reach Your Team.
Outsourcing fulfillment should not leave you guessing about what is happening with your inventory or orders.
Inventory & Order Visibility
Square1 uses Extensiv Warehouse Management System to support inventory, orders and fulfillment activity. It gives brands greater visibility into the operation while inventory and orders are being managed by Square1.
Direct Client Support
Technology is only part of that relationship.
Square1 clients also have direct access to their Client Support Coordinator by phone or email. If you need to discuss inventory, an upcoming promotion, a subscription cycle or a change in your fulfillment program, you can reach someone who knows your account.
For brands moving away from an underperforming 3PL or an in-house operation that has become difficult to manage, that combination of visibility and direct communication helps keep you connected to day-to-day fulfillment.
FIND THE RIGHT 3PL FIT
Is Square1 a Fit for Your Supplement Brand?
The right 3PL depends on more than the products you sell. Order volume, SKU count, storage needs, sales channels and the type of fulfillment support you need all affect whether a warehouse is a good operational fit.
Square1 may be worth a conversation if:
You have outgrown packing and shipping orders in-house.
Your current 3PL is creating communication or fulfillment problems.
Ecommerce order volume is growing and your internal operation is struggling to keep up.
You sell through D2C and B2B channels or expect to add channels as you grow.
Your products are suited to our temperature and humidity-controlled warehouse conditions.
Your program includes subscriptions, bundles, kits or other defined packing requirements.
You want direct communication with the people supporting your fulfillment operation.
You need a U.S.-based fulfillment partner that can support distribution across the country.
