Shopify U.S. fulfillment for international sellers

FulfillHarbor connects supported Shopify stores to a Florida fulfillment warehouse. International sellers can keep stock with us and manage U.S. orders through the MySmartMailbox dashboard. A U.S. company is not required to apply for the warehouse service. After an order arrives, you choose the shipping service and approve payment before we dispatch it.

How a Shopify order moves through the warehouse

Approved customers connect their Shopify store to the dashboard. Supported product, order and inventory information can sync with the account. The shipping approval happens after we have the packed parcel details.

1. The store order imports into your dashboard.
2. We prepare the parcel and record the packed measurements and packaging.
3. You compare the available rates and review postage, shipping service fees, pick and pack, and packaging charges.
4. You select a service and approve payment. We then purchase the label and dispatch the parcel.
5. Shipment status and tracking become available, and supported shipment updates can return to the connected store.

Decide who will check pending approvals and how often. A connected store still needs that decision from you. The cost you charge a buyer at checkout also needs to be planned separately from the rate you choose for the prepared parcel.

Review products, stock locations and delivery settings

Choose the products that will be held in Florida and keep their SKUs consistent with your warehouse inventory. If you also hold stock elsewhere, decide which location should serve each part of the business before changing your store settings.

Shopify's location guidance explains how available inventory and order-routing settings affect fulfillment. Shipping profiles also affect which locations serve products. Review the setup for your store when connecting it to us; there is no single default-location change that fits every merchant.

After approval and check-in, verify a first order through the whole process. Check the SKU and quantity, delivery address, parcel cost and returned tracking. Use the services and handling arrangements available for your products when setting customer delivery expectations.

Keep payment verification separate

For a store run from abroad, warehouse onboarding is one part of the setup. Shopify Payments eligibility depends on the business country, product and other conditions. Using a Florida receiving address does not establish a U.S. business or satisfy payment verification.

Use accurate business and owner details for the payment account that applies to you. Our guide to fulfillment without a U.S. company explains which requirements belong to the warehouse application. Ask an accountant to review the implications of holding stock and making sales in the U.S.

Before your first stock arrives

International applicants provide a valid passport, their contact or business details, a payment method, product and inventory-ownership declarations, and the signed agreement. Wait for approval and the assigned receiving instructions. We review the goods before accepting them; our storage is for cartons and bins, with no pallet storage.

You arrange international transport and U.S. customs clearance separately. FulfillHarbor does not provide customs clearance. See the transport and customs checklist for details to discuss with your chosen provider.

Register the products, expected quantities and inbound shipment before dispatch. Add tracking when your supplier provides it. The inbound shipment guide explains what needs to happen before stock is available for Shopify orders.

Shopify fulfillment costs

Postage, shipping service fees, packaging and additional work are separate. The lower pick-and-pack rate applies only to orders from the 101st onward. Storage continues while your goods occupy a bin, including months with no orders. There is no setup fee or monthly order minimum. See the full prices and applicable extra charges, including inactive storage and SKU space agreements.

Shopify subscriptions and payment-processing fees belong to your store's separate costs. To budget for fulfillment, also allow for your incoming shipment, import charges and the space occupied by stock waiting to sell.

Returns and refunds

Approved fulfillment customers receive an assigned U.S. return address. We inspect returned products, put resellable items back into inventory and flag damage. You use the receipt and condition information to manage refunds in your store. The returns page describes the processing charge and the costs that remain separate.

Choose return instructions that match the service agreed for your account. Our standard self-service shipping workflow covers U.S. destinations, so discuss any plan to send returned stock abroad before offering that option.
