You're probably dealing with

A listing going out of stock because two channels sold the last unit within seconds of each other and neither knew

A "what did I actually make on this SKU" spreadsheet that takes hours to update and is still wrong

Three label-printing tools open in three browser tabs

An FBA shipment prep checklist that requires manually building a box content file and reconciling mismatched fulfillment centers

A returns folder you haven't opened in two weeks because the math never ties out against a marketplace settlement

A profit-and-loss conversation with your accountant that ends with "I don't actually know what my margin is"

Here's what changes with Rilk

The spreadsheet goes first. Rilk runs multi-channel sync on a single stock pool, so when one channel sells a unit, every other channel sees one less within seconds — no more racing two marketplaces to the same unit, with native support for FBA, FBM, WFS, and merchant-fulfilled across every channel you're on.

The label-printing tab dance goes next. Shipping is built into Rilk — UPS, FedEx, USPS, and DHL labels print straight from the order screen to the same thermal printer you already use.

The profit conversation changes too — per-unit profit reporting reconciles against the actual marketplace settlement, including referral fees, FBA fees, return adjustments, and the freight you paid both ways, so you know within a dollar what every unit actually made you. And when something comes back, returns is a structured workflow: inspect it, decide whether it goes back to A-stock, gets a light regrading touch, or gets written off, with the refund reconciling automatically against the marketplace payout.

Capabilities that matter most for you
