On Amazon, Walmart and eBay, Rilk matches each settlement back to its orders automatically, so the fees on an order are what the marketplace charged.
Every unit keeps its serial from receiving to sale. Regrade a return, log the repair cost, and relist it under the right SKU with the original cost attached.
Free for your first 500 orders a month. Pro from $999/mo.
Connect Amazon, Walmart, eBay, Shopify or WooCommerce and your orders land in one screen. Buy labels on your own UPS, FedEx, USPS and DHL accounts and rate-shop every order.

Buy the label at the marketplace's own rates right from the order, without switching tools. Rilk went through multiple rounds of Amazon review, including the Appstore listing review and a data security assessment under Amazon's Data Protection Policy, and Amazon granted Rilk its restricted Direct-to-Consumer Shipping role on 24 August 2026.
On Amazon, Walmart and eBay, Rilk matches each settlement back to its orders automatically, so the fees on an order are what the marketplace charged, not an estimate. Label re-rates, refunds and adjustments show up against the order they belong to. On other channels you import the payout file and Rilk does the matching.
Every unit keeps its serial from receiving to sale. Regrade a return, log the repair cost against that serial and relist it under the right SKU, with the original cost following the unit. Returns received go straight back into sellable stock in the right bin.
Freight, duty and the other costs on a purchase order are spread across every unit on it, so your cost per unit is right the day the shipment is received, and so is your profit.
Rilk is free for your first 500 orders a month. Pro starts at $999 a month, with each order shipped metered at $0.30 ($0.05 if Amazon-fulfilled) and credited against that minimum. Ultimate adds retailer EDI and more than one company, quoted to fit. No per-user seats, no per-channel fees.
