How it works

Connect your store, send your inventory, and we ship every order from there.

How it works

From Your Store to Your Customer's Door

Once your store is connected and your stock is on our shelves, every new order ships without you touching it.

    We pick, pack and ship

    Each order is packed with care and labeled for UPS, USPS, FedEx or DHL, based on size, speed and cost.

  4. 04

    Tracking numbers sync back to your store, and you see stock levels and order status as they change.

Common questions

Getting Started with Sonic Fulfillment

The questions sellers ask most before sending their first shipment.

Which stores can I connect?

Marketplaces such as Amazon, eBay and Facebook Marketplace, live selling apps such as TikTok Shop and Whatnot, and your own store on Shopify or another platform. Tell us where you sell and we'll confirm how orders reach us.

How do I send my inventory?

Ship cartons or pallets to our Southern California warehouse. We unload, count and inspect every unit, and flag any discrepancies to you.

Which carrier will my orders ship with?

UPS, USPS, FedEx or DHL. We choose the service for each package based on size, speed and cost.

Do you ship outside the US?

Yes. We ship to customers worldwide with DHL, FedEx, UPS and USPS international services, and prepare the customs forms for every package.

How do I keep track of stock and orders?

Every client gets a login to their own dashboard, with inventory for every SKU, order status and tracking numbers. See the dashboard preview.

What happens with returns?

We receive returns, inspect them and restock sellable items so they're ready to ship again.
