Your best pieces deserve
more than foot traffic.
Kommandr OS is software for vintage and secondhand shops that runs the online half of the business: listing your stock from one upload, consignor splits and payouts, a branded storefront on your own domain, and true profit after fees.
Kommandr OS is not a cash register. No card-present checkout, no cash drawer. Keep whatever works at your counter — what this replaces is the listing night, the consignor spreadsheet, and the guesswork in your margins.
One flat plan — $397/mo at public launch. Founding members keep $197/mo for life.

What shop owners actually say
A shop with real inventory is showing it to whoever happens through the door that week. The mid-century chair that a collector three states away would pay double for never gets seen by them, because getting the floor online is a job nobody has time for after closing.
Who brought what, what sold, what split applies, what was already paid — reconstructed monthly from tags, memory and a notebook. It is the most trust-sensitive math in the shop and it is usually the least systematic.
Gross sales are visible; margin by category is not. Without fees and cost of goods tracked per piece, buying decisions get made on instinct about what feels like it moves — which is how a shop ends up full of the wrong inventory.
What Kommandr OS does about it
Mark a piece as consignment, set the consignor and their split percentage, and what you owe accrues as items sell. The payout ledger shows what is owed per consignor and what you have already paid, so settlement is a report you read rather than an evening you lose. Splits are calculated on net proceeds and labelled as net — because a consignor who is told "gross" and paid on net stops being a consignor.
Photograph a piece once and list it to your own accounts across the local marketplaces and eBay, plus your own storefront. The buyer who wants that specific chair is usually not the person walking past your window.
Your shop, your name, your URL — with checkout, orders and reviews. It is the shop's online front, not a rented booth on somebody else's platform, which matters when the goal is a business you own rather than an audience you rent.
Cost of goods, marketplace fees, and a tax set-aside recorded per item, so you can see which categories genuinely carry the shop and buy accordingly.
Real quotes from working shops go here as early access begins — carrying the disclosure that those testers receive Kommandr OS free in exchange for honest feedback. We do not buy or invent testimonials, so this stays empty until it can be true.
Keep the counter. Fix everything else.
Consignors, payouts, online listings, a storefront on your own domain, and books you can trust.
Software for vintage shops — FAQ
Is Kommandr OS a point-of-sale system for my shop?
No. Kommandr OS has no card-present checkout and no cash drawer, so it does not replace the register at your counter. It runs everything around the counter: listing your stock online, consignor records and split payouts, a branded storefront on your own domain, and books that show true profit after fees. Most shops that use it keep a simple register for the floor.
What software do vintage and secondhand shops use to sell online?
Most use some combination of a point-of-sale for the floor and a separate listing tool for online, with a spreadsheet holding the consignor math in between. Kommandr OS replaces the second and third of those: one upload lists to your own marketplace accounts and your own storefront, and consignor splits and payouts are tracked in the same system as the sale.
How does the consignment split tracking work?
You mark an item as consignment, record the consignor and their percentage, and as pieces sell the amount owed accrues automatically. The payout ledger shows owed versus already paid per consignor. Splits are computed on net proceeds — what actually cleared after marketplace fees — and the screen says so, so there is no gap between what a consignor is shown and what they are paid on.
Do you handle in-store sales?
Only in the sense that inventory you mark sold is updated everywhere in the system. The transaction at the counter itself belongs to your register. If a shop needs the register first and foremost, a consignment point-of-sale is the more honest purchase and we will say so.
We only sell in the shop and have no plans to sell online. Should we buy this?
No. If the floor is the whole business, this is not the right tool and you should keep your money. It fits shops where a real share of inventory sells online, or shops that want that and are blocked by how long listing takes.
