ShipStation on Oliver POS

Oliver POS writes every in-store sale to WooCommerce as a standard order with the customer attached, so the ShipStation Integration for WooCommerce picks up shippable in-store sales the same way it picks up online orders. The connector pulls the order into ShipStation's "Awaiting Shipment" tab the moment WooCommerce moves it into a processing status, reading the order number, customer name and email, full shipping address, line items with SKU and quantity, per-product weight and dimensions, declared value, the requested shipping method, gift-message notes, and any custom fields the retailer has set up.

Because the underlying data shape is identical for online orders and orders made with Oliver, ShipStation's rate engine, address validation, automation rules, and branded tracking pages all behave exactly the same. An in-store sale flagged for home delivery appears in ShipStation seconds after the till closes the order, with the destination address pre-populated, the right shipping service auto-selected by the retailer's automation rules, and the parcel weight calculated from the WooCommerce product catalog.

Most retailers running ShipStation alongside a separate POS end up with two parallel shipping queues. Online orders flow into ShipStation automatically — picked, packed, labelled, scanned. In-store sales that need to be shipped — the customer ordering an out-of-stock size, the gift the buyer wants sent to their nephew, the bulky item nobody wants to carry home — get manually entered into ShipStation from a paper note or a separate POS export. The dispatch clerk picks the order in the morning, hand-types the address into ShipStation, guesses the right rate, prints the label, and hopes the address was typed in correctly.

With Oliver POS feeding WooCommerce, the second queue disappears. The cashier flags the sale for delivery at the payment screen, the customer's shipping address is already attached, and the order lands in ShipStation's "Awaiting Shipment" tab alongside the morning's online orders. The dispatch clerk picks, packs, and prints once. Standard in-store sales — the overwhelming bulk of till volume — never reach ShipStation at all, because Oliver writes them with no shipping method required and ShipStation's order filters skip them. One queue, one rate engine, one set of carrier accounts, one branded tracking experience for the customer regardless of channel.

The cashier puts the sale through on Oliver POS, looks up or creates the customer's account, and on the payment screen toggles home delivery (or chooses the appropriate delivery method — back-order, large-item courier, BOPIS-deliver-later). The customer's saved shipping address is attached automatically; if they're a walk-in, the cashier enters the address there and then. Oliver writes the WooCommerce order with line items, taxes, payment method, and the shipping address, then closes the sale and prints the receipt. The standard WooCommerce → ShipStation webhook fires the moment the order moves into Processing status, and the order appears in ShipStation's order grid with everything the shipping team needs to print.

The dispatch clerk picks the order, ShipStation suggests the cheapest carrier and service based on the destination and weight, the label prints, and the tracking number writes back to the WooCommerce order. The customer gets ShipStation's branded tracking email, the order moves to Completed once the carrier scans the parcel, and the Oliver POS sales report continues to show the original in-store transaction as part of the day's till total. Refunds work the same way — a refund issued from the Oliver till creates a WooCommerce refund action, which ShipStation reflects as a cancelled or returned shipment in the order history, and where the retailer uses ShipStation's returns portal the customer can request a return label themselves regardless of whether the sale originated online or at the counter.

ShipStation on Oliver POS suits North American multi-channel retailers running serious shipping volume — boutiques fulfilling 50+ parcels a day, specialist hobby shops, gift shops with a strong Christmas shipping season, and any brand juggling USPS, UPS, FedEx, and DHL contracts side by side. It's especially powerful for retailers running multiple Oliver POS stores that ship from one warehouse: ShipStation's store-by-store filtering lets the shipping team see every store's flagged-for-delivery orders in one queue while preserving the source location on every parcel. Retailers with negotiated carrier rates already loaded in ShipStation keep those rates on in-store orders without lifting a finger.
