Software for e-commerce sellers

Solo or small-team operators selling on Amazon, eBay, and Walmart — without losing a Sunday to a spreadsheet.

You're probably dealing with…

• A listing going out of stock at 2 p.m. because Amazon and eBay sold the last unit within thirty seconds of each other and neither one knew.
• A spreadsheet of "what did I actually make on this SKU" that takes you four hours to update and is still wrong.
• Three label-printing tools open in three browser tabs — one for FBA, one for FBM, one for the wholesale order you took on the side.
• An FBA shipment prep checklist that requires you to manually build a box content file, generate labels, and reconcile when half the units show up at a different fulfillment center than the plan said.
• A returns folder that you haven't opened in two weeks because every refund involves reconciling against a marketplace settlement, and the math doesn't tie out.
• A profit-and-loss conversation with your accountant that ends with "I don't actually know what my margin is."
• The slow realization that you spend more time managing tools than you spend buying inventory.

Here's what changes with Rilk

The first thing that goes is the spreadsheet. Rilk runs multi-channel sync on a single stock pool, so when Amazon sells one, eBay sees one less within seconds. No more racing two marketplaces to the same unit. Native support for FBA, FBM, WFS, and merchant-fulfilled across every channel you're already on.

The second thing that goes is the label-printing tab dance. Shipping is built into Rilk — UPS, FedEx, USPS, and DHL labels print straight from the order screen, to the same thermal printer you've already got. Buy postage, print, scan, ship. One screen, one workflow.

The third thing that changes — and this is the one operators don't expect — is the profit conversation. Rilk's per-unit profit reporting doesn't estimate. It reconciles against the actual marketplace settlement, including referral fees, FBA fees, return adjustments, the freight you paid to get the unit into the warehouse, and the freight you paid to ship it out. You'll know within a dollar what every unit actually made you.

And finally, when something does come back, returns is a structured workflow, not a black hole. Inspect it, decide whether it goes back into A-stock, gets a light regrading touch, or gets written off. The refund reconciles automatically against the marketplace payout. Returns stop being the thing you dread on Friday afternoons.

Capabilities that matter most for you

• Multi-channel sync — One stock pool, every channel. Sell the same unit on Amazon, eBay, Walmart, BackMarket, or Shopify without overselling.
• Shipping — Buy and print UPS, FedEx, USPS, and DHL labels from the order screen. No separate shipping software. No separate bill.
• Per-unit profit reporting — Real margin after fees, freight, and returns. Verified against marketplace settlements.
• Returns — Inspect, restock, lightly re-grade, or write off. Refund reconciles automatically.
• Purchase orders — Track what you ordered, what landed, and what it cost — including freight and duty rolled into your true cost basis.

A day at e-commerce seller with Rilk

• 7:30 a.m. — Open Rilk. Overnight orders are already in: Amazon FBM, eBay, a couple of Walmart, one Shopify. All in one list, sorted by promised ship date.
• 8:00 a.m. — Pick the morning batch from one screen. Rilk prints pick lists straight to the warehouse printer.
• 9:30 a.m. — Pack, weigh, print UPS and USPS labels at the pack station. Tracking numbers push back to each marketplace automatically.
• 11:00 a.m. — FBA shipment prep — build a shipment in Rilk, generate the box-content file, print FNSKU and shipment labels, and you're loading the pallet by lunch.
• 1:30 p.m. — A return comes in from Amazon. Scan the unit. Rilk pulls up the original order, fees, and refund. Inspect, mark as A-stock, restock. The marketplace refund reconciles against the original sale automatically.
• 3:00 p.m. — Cross-channel relist: a slow-moving Amazon SKU drops onto eBay with one click. Same stock pool, no double-counting.
• 5:00 p.m. — End-of-day glance at the profit dashboard. Today's gross, today's fees, today's net. By SKU, by channel, by order. The number ties out to the bank account at the end of the month.
