ShipLab connects a Shopify store to UPS, DHL and more carriers, on the merchant's own accounts and negotiated rates. It shows live carrier rates at checkout, creates labels one by one, in bulk or automatically (PDF and thermal ZPL/EPL), generates paperless commercial invoices, tracks packages and creates return labels — all from Shopify Admin. Customers can collect parcels at a UPS Access Point, DHL Service Point or Canada Post post office. Rate rules adjust prices by weight, cart total, destination and product, and orders can ship from several warehouses, each with its own carrier account.

Pricesmith changes Shopify prices across the whole catalog by rule — tag, vendor, type, SKU or metafield — and previews every variant before anything is written. Formulas set price, compare-at, cost per item and money metafields in one pass, so a sale can move the old price to compare-at for a strike-through or price from cost to keep a margin. Sales can run now or on a schedule that reverts itself. Every apply is snapshotted, so one click restores exactly the prices that were there, and an append-only log records each change and its source. Quantity tiers apply at checkout through a Shopify Function.
