What Rilk does
FAQ
Questions sellers ask before they switch
Straight answers. Anything else, book a call and ask an operator.
What does Rilk cost?
Three tiers. Free is $0 with no credit card, for one company: Amazon, Walmart, eBay, Shopify and WooCommerce connections, orders, product catalog, shipping labels, rate shopping and bulk shipping, with your first 500 orders each month included. Pro is from $999/month minimum for one company and adds warehouse, bins and serials, purchase orders and FBA inbound, picking, returns and regrading. Ultimate is custom-priced — book a call — for businesses selling through retailer EDI or running more than one selling entity, and adds advanced analytics and a dedicated customer success manager. Past the first 500 orders, usage is $0.30 per order shipped, $0.05 for Amazon-fulfilled orders; cancelled and unshipped orders are never billed, and Pro and Ultimate bill from order one against their monthly minimum. Every account also gets one 14-day Pro trial, no credit card, started from your billing settings before you add a card.
Is there a free trial?
Yes — 14 days of Pro, with no credit card. It is one trial per account, ever, and you start it yourself from your billing settings once you have an account; creating one is free. The trial opens up Pro — warehouse and bins, serial tracking, purchasing, regrading, FBA and WFS — not Ultimate, which stays quoted per operation. When the 14 days are up you choose: add a card to stay on Pro, or move to Free. Nothing is charged automatically, because there is no card on file. The Free plan is a separate thing — it does not expire, and staying on it does not use up your trial.
Does Rilk replace ShipStation?
Yes. Label printing and rate shopping are on the Free tier: UPS, FedEx, USPS and DHL on your own accounts, plus Amazon Buy Shipping and Walmart Buy Shipping. Most sellers drop ShipStation first and keep their old inventory system until they are ready to move that too.
Which marketplaces does Rilk connect to?
50+ channels, split by plan. Free connects Amazon, Walmart, eBay, Shopify and WooCommerce. Pro adds BackMarket, Newegg and Temu, plus Bonanza (connects today, sync still being built) and PayWhirl for subscription orders. Ultimate adds Walmart DSV, Wayfair, 25 retailers on the Mirakl platform — Macy’s, Best Buy, Nordstrom, Kohl’s, Lowe’s and more — 21 retailers on SPS Commerce, and EDI connections to Home Depot, Lowe’s, Macy’s, Overstock and Zoro. One inventory pool, one order queue, and no per-channel fee on any plan.
Will Rilk stop me overselling when the same stock is listed on several channels?
Yes. Rilk keeps one stock pool per product rather than a separate count per channel. As soon as an order imports from any connected channel, that pool is decremented and the new available quantity is pushed out to every other listing of the same product, so the same unit cannot be sold twice on two channels. The sync runs on every connected channel — Amazon, Walmart, eBay, Shopify, BackMarket and the retailer marketplaces — not just the one the order came from, and it fires again whenever you receive stock, ship, transfer between bins or process a return.
Can I manage FBA and WFS inventory alongside my own warehouse?
Yes, on Pro and up. Create FBA and WFS inbound shipments and process FBA removals without leaving Rilk, alongside the merchant-fulfilled orders you pick and ship from your own warehouse.
Can I move from SellerCloud, ShipStation or ChannelAdvisor?
Connect your marketplaces and carrier accounts and orders start flowing the same day; products and listings pull in from the channels you connect. No implementation contract, no sales call to buy. Start on Free, ship from Rilk, and move inventory, purchase orders and serials over once the UI is muscle memory.
Does Rilk track serial numbers and IMEIs?
Yes. Every unit carries its serial from receiving through grading, listing, shipping, returns, servicing and resale, and profit is reported per serial from marketplace settlement data, not a spreadsheet estimate.
