Consignment store software should handle the half of the shop your register never sees: who brought each item in, what split they agreed to, when it gets marked down and what they are owed when it sells. Your point-of-sale system rings the sale. The consignor side is where the hours go, and where the phone calls come from.
This guide is for clothing, furniture and home goods consignment shops that add up payouts by hand from sales reports. It shows the app we would build and where the owner stays in charge. For the bigger picture, see our guide to AI for small business and our hub on AI for retail stores.
What should consignment store software handle?
Consignment store software should handle consignor records, item intake, markdowns, payouts and a way for consignors to check their own balance. Each item needs a tag that ties it to one consignor and one agreement. When it sells, the sale should land on that consignor's statement without anyone typing it in again.
A shop like this has two sets of customers. Shoppers buy, and consignors supply. Our guide to retail CRM covers knowing your regular shoppers. This post is about the second group, the people whose items fill your racks.
The records behind it:
- Consignors. Name, contact choices, the signed agreement and the split that applies to them.
- Items. A photo, a description, the intake date and a tag carrying the consignor's number.
- Markdowns. The price steps your shop sets as an item ages on the floor.
- Sales. Each sold item matched to its consignor and its split.
- Payouts. What each consignor earned in a period, and the date it was paid.
Why do sales reports and spreadsheets make payouts so hard?
Sales reports and spreadsheets make payouts hard because neither knows who owns each item. The register shows what sold, not whose it was or what split applies. So someone exports a report, sorts it by tag number, matches lines to consignors in a spreadsheet and works out each share by hand.
Then the calls start. "Did my lamp sell?" "When do I get paid?" "Is my coat still there?" Each one means a person stops to look up a tag.

The tools that fall short:
- Point-of-sale systems. Great at ringing sales, but many treat stock as the shop's own, with no consignor or split.
- Spreadsheets. Flexible, but the matching is manual and one sorting slip can shortchange a consignor.
- Boxed consignment apps. Close, but they bend your markdown and payout rules to theirs, and some want to run your register too.
- Online marketplace tools. Made for many sellers paying out to each other, which our guide on how to build a marketplace app covers. One shop paying its own consignors is a simpler job.
What we build: consignment management software, screen by screen
We build the consignor side of your shop as one app that sits next to your register. Intake creates tagged items tied to a consignor, markdowns follow your schedule, sales flow in from your point-of-sale system, and payout statements draft themselves for the owner to check. Consignors get a portal of their own.
It is one of our full web applications, with logins for the owner, the floor staff and each consignor. Depending on the investment package you pick, you get either the right to use the app or full ownership of it, and your consignor records stay yours.
- Consignor records. Each consignor's agreement, their split and how they like to hear from you. A split change needs the owner's sign-off and lands in the history.
- Intake. Staff photograph each item, describe it and print a tag with the consignor's number. A recall check sits in the intake steps. The CPSC's guide for resellers (opens in a new tab) says its rules reach consignment and thrift stores and tells them to review the recall list before taking a product in or selling it.
- Markdown schedule. The owner sets the price steps by age. Each morning, a list shows which tags drop today.
- Sales. The app reads sold items from your point-of-sale system. The register stays exactly as it is.
- Payout statements. Each period, the Finance Agent drafts a statement per consignor: what sold, the price, the split and the share. The owner reviews the batch and approves every payout. The IRS's guide to business records (opens in a new tab) says to keep supporting documents that show the amounts and sources of your income, and these statements give you a clean trail.
- Consignor portal. Each consignor sees their items in stock, sold and marked down, plus the balance owed. The FTC's guide to protecting personal information (opens in a new tab) advises keeping only the personal details you need and limiting access to what each job requires. In the same spirit, a consignor sees only their own items.
- End-of-term notices. When an item reaches the end of its term, the app drafts a pickup notice under your own agreement. Consignors who agreed to texts get it by text and can opt out at any time; the rest get an email. Rules on unclaimed items vary, so check your state's rules.
This is an illustration, not a customer story. Fiona runs a consignment shop for women's clothing and small furniture. On payout day, the Finance Agent hands her a drafted batch built from the period's sales. One statement shows a side table sold at a price below the markdown floor, so the app flags it. Fiona checks the sale, finds a staff discount rung up by mistake, fixes the share and approves the batch. Consignors who agreed to texts get a note that their statement is ready, and any of them can opt out.
How do we build and test it in your shop?
We start with one full payout period, running the app beside your current process and comparing each consignor's statement line by line before switching over. Ahead of that, you approve a written spec of your agreement terms, split rules, markdown steps and payout calendar, and nothing is coded until you do.
The spec also sets the small rules that matter on the floor, such as who can change a split, how a return reverses a share and what happens when a tag is lost.
With your own consignor data, we check these before switching over:
- Each sale from the register lands on the right consignor at the right split.
- A return reverses the consignor's share on the next statement.
- Markdowns hit the right tags on the right day and never go below the floor you set.
- A consignor logged in to the portal sees only their own items.
- A payout batch matches a hand count for a sample of consignors.
The app connects to your register and your accounting software. It is consignment software for small business built around your terms, not a template.
What stays with the owner?
The owner keeps the money calls and the people calls. The owner approves every payout and every split change, sets the markdown schedule and decides what to accept at intake. Tax questions about payouts go to the shop's accountant. The app keeps the record, and the Finance Agent only drafts and flags.
- Pricing a new item, and turning down one that will not sell, stay with the person at the intake counter.
- A consignor who disputes a statement gets a call from the owner.
- Whether to extend a term or donate unclaimed items follows your agreement and the owner's word.
Stock you buy outright is a different job. Items that never come back in stock do not need reorder points, so our guides to inventory forecasting software and back-in-stock notifications fit the new-goods side of a mixed shop. Good consignment shop software lets your people spend time on the floor instead of on spreadsheets. Same team. Same jobs. More capacity.
Frequently asked questions
How do consignment stores work?
Consignment stores sell items for their owners and keep a share of each sale. The consignor brings items in, agrees to a split and a term, and the shop prices, displays and sells them. After a sale, the shop pays the consignor's share on a set schedule. Unsold items are picked up or handled as the agreement says.
How do you run a consignment business?
Run a consignment business on clear terms and clean records. Write one agreement every consignor signs, tag every item to its owner, follow a steady markdown schedule and pay on the same calendar each period. Answer balance questions quickly, and keep every payout statement on file.
How do you price consignment items?
Price consignment items by condition, demand for that type of item, the season and how fast similar pieces have sold in your shop. Start fair, then let your markdown schedule lower the price as the item ages. Your own sales history is the best guide over time.
What is consignment inventory?
Consignment inventory is stock that sits in your shop but still belongs to the consignor until it sells. The shop holds and sells it under an agreement, and the consignor is paid a share after the sale. That is why each item needs a record of its consignor.
Next step
Book a free workflow consult and bring last period's sales report and one payout spreadsheet. We will trace a few items from intake to payout, mark each step someone did by hand and show where one record would carry it. We work from the Kansas City metro and meet owners face to face or by video call.
