Our Supplement Fulfillment Process
Supplements aren’t typical retail products, because they require special care due to compliance standards, shelf-life considerations, and customer expectations around freshness and quality. Understanding this, we’ve shaped our fulfillment approach specifically around these needs.
Step 1 – Receiving and Thorough InspectionAs soon as your shipment reaches our warehouse, we physically verify quantities, examine packaging, and document details like lot numbers, expiration dates, and batch codes. This is how we guarantee accuracy, compliance, and immediate traceability. |
Step 2 – Safe and Organized Product StorageOnce inspected, your supplements are placed into maintained storage areas, clearly labeled and organized to prevent mix-ups or contamination. For products sensitive to temperature or humidity, we provide climate-controlled spaces, preserving product integrity throughout storage. |
Step 3 – Immediate Order IntegrationThere’s no need to manually upload orders or worry about syncing data, since we’ve automated the entire process. Orders from your Shopify store, Amazon account, or other online channels flow directly into our fulfillment platform the moment they’re placed. This eliminates manual entry errors and speeds up processing. |
Step 4 – Picking, Customized Packaging, and Double Checks
|
Step 5 –Shipping with Continuous Tracking and SupportWe work closely with trusted carriers, selecting shipping methods that align with your brand’s priorities, whether domestic or international. As soon as your customer’s order ships, tracking information is immediately shared. Our team also proactively monitors shipment status, solving any potential delays or issues swiftly. |
