An App to Track Inventory, Research and Manage Your Antiques and Vintage Finds
What is Lineage &
Who is Lineage For?
Lineage is an inventory management app designed for the workflows and process antique and vintage resellers see in real world settings. Unlike general retail inventory software, the Lineage app understands:
-
Buying in lots
-
Splitting costs across multiple items
-
Selling across booths, shows, shops, and online marketplaces
-
Tracking aging inventory and true profit
-
Reseach and provenance verification via AI tools
-
Fast image processing directly from your phone
Lineage works on desktop and mobile, so you can log items at auctions, estate sales, or in your booth—then review performance and run reports wherever you like.
Lineage is built for people who manage, buy and sell one-of-a-kind items, not SKUs.
Lineage is ideal for:
-
Antique booth dealers
-
Vintage and collectible resellers
-
Estate sale and auction buyers
-
Pickers and small dealers
-
Antique store managers and owners
-
Multi-booth or multi-location sellers
-
Families managing inheritance of heirlooms
If you’ve ever used a spreadsheet, notebook, or phone photos to track inventory, Lineage is for you.
How Does Lineage Work?
How Does Lineage Work?
Capture, Research and Inventory
Log items the moment you buy them—at auctions, estate sales, shops, or on the road.
Add photos, purchase costs, and use AI embedded research tools directly from your phone or desktop so nothing gets lost later.
Track Lots, Items, and Locations
Easily track where everything lives—booths, shelves, storage bins, shows, warehouses, or family member's homes—and update status as items move, list, transfer ownership or sell.
Price Inventory with Confidence
Understand true cost and margin before you price or negotiate.
Lineage connects lot costs to individual items so you know real profit potential—not guesses—before items hit the floor or go online.
Know What You’re Earning
See profit, sell-through, and aging inventory at a glance.
Understand what’s selling, what’s sitting, and what’s costing you money so you can make smarter buying and pricing decisions over time.
See what’s actually working:
-
Profit per item
-
Profit per lot
-
Sell-through rate
-
Time to sale
-
Aging inventory
No more guessing whether you “did okay” on a buy.
Calculate Profit and Sales
Set prices based on:
-
Cost basis
-
Target margin
-
Comparable sales (manual or imported)
Lineage helps you avoid underpricing—and shows you when inventory is aging and needs adjustment.
Price with Confidence
Assign Locations & Status
Know exactly where each item is and what stage it’s in:
-
Booth location
-
Shelf, case, or bin
-
Show, storage, or listed online
-
Status: in stock, on hold, sold
Perfect for sellers with multiple booths or rotating inventory.
Each item gets its own record with:
-
Photos
-
Description and notes
-
Cost basis
-
Category and attributes
-
Unique ID or tag number
This makes every item searchable, trackable, and measurable.
Create Item-Level Records
Record auction buys, estate sale hauls, or individual finds.
-
Purchase date and source
-
Total lot cost
-
Fees, tax, and buyer’s premium
Lineage automatically helps distribute lot costs across individual items.
Track Purchases by Lot or Item
