Best Inventory Apps for Antique Booth Vendors and Resellers

The best inventory app for an antique booth vendor is the one that matches how the seller actually works. For one booth, that may be a disciplined spreadsheet plus the mall's portal. A seller who runs markets and controls checkout may benefit from a retail point-of-sale system. A multi-channel reseller may care more about cross-listing. A booth operator who needs to connect item costs, selling locations, fees, and recorded sales may prefer seller-focused software.

There is no honest universal winner. This guide compares seven options by the questions that matter in a real antique-booth workflow:

• Can you record an item and its acquisition cost from your phone?
• Can you distinguish physical storage from the location where it is offered for sale?
• Can you connect the item to a recorded sale?
• Can you account for booth rent, commissions, and other location fees?
• Can you compare your records with the mall's official statement?
• Can you export your data if you change systems?

Quick answer: Start with the least complicated system that keeps those records current. Use the mall portal for the transaction and payout data it controls. Choose a separate inventory app only when it solves a gap the portal leaves open.

What an antique booth inventory app should track

Before comparing brands, define the records you need. A useful system should answer five questions.

1. What is the item?

Give each one-of-a-kind piece a permanent item number and a plain description. The number on the tag, your inventory record, and the mall statement should point to the same item whenever the mall's system supports it.

2. What did it cost?

Record the acquisition cost when you source the item. If you want to track direct repair or preparation costs, decide where those fields belong before importing hundreds of records. Historical costs support your decisions; the software should not be presented as choosing prices or sourcing inventory for you.

3. Where is it?

A storage shelf and a selling location are different facts. “Garage shelf B” describes where the item physically sits. “Oak Street Mall, Booth 14” describes where it is offered for sale. A system should represent your locations clearly enough that transfers do not erase the item's history.

4. What happened when it sold?

Keep the actual sale amount, sale date, and selling location. Do not delete the inventory record when the item leaves the booth. You will need that history when a mall statement arrives or a buyer returns an item.

5. What remained after the costs you record?

Sale price minus acquisition cost is not the whole booth result. Rent, commissions, payment fees, and other location costs matter. Different apps use “profit” to mean different things, so inspect the calculation instead of trusting the label.

If you are still designing those records, read our practical antique booth inventory-tracking guide and guide to calculating real antique-mall profit before choosing software.

1. Spreadsheet plus your mall portal: best for a simple operation

A spreadsheet remains a reasonable vendor mall inventory tracker. You control the columns, formulas, and item-number format. You can add acquisition cost, physical location, selling location, list price, sale price, and sale date without adopting another company's workflow.

Best for: A seller with one booth, a manageable number of active items, and the habit of updating one master file.

Why it can work:

• You can model the exact fields your operation needs.
• Your records remain portable.
• Sorting and filtering answer many basic questions.
• The mall portal can supply the official transaction, statement, and payout data.

What to test: Mobile entry, duplicate copies, broken formulas, item transfers, backups, and monthly fee allocation. Keep one item table rather than a separate workbook for each booth. Record location expenses in a separate table so rent is not silently attached to the wrong month.

A spreadsheet is not “wrong.” It becomes expensive when maintaining it takes more time than the questions it answers.

2. MaxIMS: best for inventory, location fees, and recorded sales together

MaxIMS is built for makers, resellers, craft vendors, and antique booth operators. Its core workflow connects item inventory, acquisition-cost inputs, selling locations, fixed or percentage location fees, recorded sales, and profitability information.

Best for: A booth vendor or small reseller who wants seller-focused records rather than warehouse software or a cross-listing platform.

The current MaxIMS feature set includes mobile sales recording, item and cost records, configurable selling locations, location-fee calculations, reporting, exports, and mall-statement reconciliation. Capabilities and limits vary by tier.

The current pricing is:

• Starter: $0, up to 50 inventory items, one selling location, and basic sales tracking.
• Pro: $15/month or $150/year, unlimited items, up to five locations, cost-of-goods tracking, multi-location fee calculations, basic reporting, and exports.
• Premium: $25/month or $250/year, unlimited locations, up to 10 users, consignment tracking, and the full reporting suite.

Paid plans list a 30-day free trial. Confirm the live limits before moving a large catalog.

What to test: Enter a representative set of items, record one discounted sale, add your actual rent and commission structure, and compare the result with a real mall statement. MaxIMS records history for the seller to review. It does not provide automated pricing, repricing, demand prediction, or comps sourcing.

3. Sortly: best for a visual catalog and flexible organization

Sortly is a general inventory app built around photos, custom fields, folders, tags, mobile scanning, check-in/out, and inventory reports. Its folder structure can represent a booth, case, shelf, storage area, or another grouping you define.

Best for: A seller whose first priority is documenting and locating items, especially a large visual catalog with condition notes or photos.

As checked August 9, Sortly's Free plan listed 100 unique items and one user. Advanced displayed $49/month, with a first-year annual promotion shown as $24/month equivalent billed at $288. The pricing page says renewal discounts differ, so do not treat the promotional rate as permanent.

Sortly's first-party materials emphasize inventory quantity, value, movement, item flow, and transaction history. They do not position it as a payment-processing POS or a complete antique-booth net-profit calculator.

What to test: Whether your sales, mall commissions, rent, and statement-reconciliation process fit cleanly without a second profit system. Also check which label, report, and scanning features require a paid tier.

4. Square for Retail: best when you run the checkout

Square for Retail combines payment processing, item records, inventory, and sales reporting. That can be useful at markets, pop-ups, or an independent shop where the seller rings the sale.

Best for: A vendor who controls checkout and wants inventory tied to the payment workflow.

Square Free listed no monthly subscription fee per location, with payment-processing fees of 2.6% + 15¢ for tap, dip, and swipe transactions and 3.3% + 30¢ online. Square Plus listed $49/month per location, lower displayed processing rates, and a 30-day trial.

The Free tier lists item and SKU creation, low-stock alerts, sales insights, and reconciliation reporting. Plus adds unit costs, inventory history and counts, bulk intake, barcode-label printing, vendor and purchase-order management, and a cost-of-goods report with revenue, profit, and margin.

What to test: If every booth sale is rung through the mall's register, Square may not receive the transaction automatically. It also does not replace the mall's dealer-split, rent, commission, or payout system. Plus is priced per location, which matters for multi-venue sellers.

5. Shopify POS: best for a Shopify-centered resale business

Shopify POS shares inventory with a Shopify online store and supports in-person checkout from a mobile device. Its fit is strongest when ecommerce and physical selling are parts of the same business.

Best for: A reseller who already uses Shopify, or plans to make a Shopify store the center of online and in-person inventory.

Shopify listed Basic at $39 month-to-month or $29/month billed yearly. Casual in-person selling features are included with paid Shopify plans. POS Pro was listed as an additional $89/month for each activated Pro location.

Basic listed centralized inventory management and 10 inventory locations. POS Pro adds deeper retail functions such as inventory counts, purchase orders, low-stock alerts, staff roles, and professional retail reports. Shopify's profit reports use recorded cost per item to calculate gross profit and margin; missing cost at the time of sale can affect historical reporting.

What to test: Which reports your Shopify plan includes and whether gross profit is enough for your decisions. Gross profit does not automatically account for booth rent, mall commission, restoration costs, mileage, and every other operating expense.

6. Vendoo: best when cross-listing is the main job

Vendoo is a reseller inventory and cross-listing platform. It supports marketplace listings, importing, delist/relist workflows, inventory records, analytics, and mobile apps.

Best for: An antique or vintage seller whose largest operational problem is keeping one-of-a-kind items current across online marketplaces.

Vendoo Starter listed $14.99/month or $12.49/month billed yearly, with a 14-day trial that requires a payment method and begins billing unless canceled. Starter listed unlimited items, unlimited crossposting, supported marketplace integrations, inventory management, and analytics.

Vendoo's analytics include revenue and profit views, average sale price, sold and listed item counts, and marketplace, category, and brand breakdowns. Sellers can manually enter in-person or unsupported-marketplace sales. Not every integration or automated sale-detection behavior is available on every device or channel.

What to test: How booth locations, rent, commissions, and mall statements will be represented. Vendoo is not an antique-mall POS or dealer portal, and booth sales generally require manual entry unless another supported workflow supplies the data.

Sources: Vendoo pricing, analytics guidance, and marketplace/mobile limits.

7. Your mall's vendor portal: best for official mall records

If your antique mall provides a vendor portal, use it. The portal is connected to the mall's checkout and settlement process, so it is often the closest record of what the mall rang, discounted, returned, and paid.

Best for: Any vendor who needs to verify the mall's official transactions and payout.

A vendor usually does not choose this software. The mall chooses a retail or consignment platform and gives vendors access to its portal. Capabilities therefore vary by mall and provider. Some portals show live sales, statements, or payout reports. Others expose less detail.

What to test:

• Does the statement include your permanent item number?
• Can you export transactions?
• Are discounts, returns, commissions, and card fees visible?
• Does the portal cover only this mall?
• Does it store your original acquisition cost or outside inventory?

Treat the portal as an authoritative source for the data the mall controls, not as a guaranteed complete business record. Your own system may still need to connect those transactions to costs, storage stock, other selling locations, and expenses the mall never sees.

How to choose: run one real workflow through each finalist

Do not choose from a feature grid alone. Use the same small batch in each serious candidate:

1. One ordinary item with an acquisition cost.
2. One repaired item with an additional direct cost.
3. One high-value item with several photos.
4. One item moved from storage to a booth.
5. One discounted sale.
6. One item sold through another channel.
7. One return or void.
8. One month of real location fees.

Then complete the same tasks:

• Add an item from your phone while sourcing.
• Find it by item number and description.
• Distinguish physical storage from selling location.
• Record the actual sale amount.
• Enter the fees from your vendor agreement.
• Compare the records with the mall statement.
• Review the result by item and location.
• Export the data in a usable format.
• Confirm what happens if you cancel or downgrade.
• Count the steps you will repeat every week.

The best antique booth inventory software is not the product with the most checkmarks. It is the system you will keep current and that answers the next decision without requiring another reconstruction project.

If you need inventory, location fees, sales, and profitability in one seller-focused workflow, explore MaxIMS. Start free with a representative batch, then compare the records with your actual mall statement before moving the rest of your catalog.

Frequently asked questions

What is the best inventory app for antique booth vendors?

There is no universal winner. A small seller may do well with a spreadsheet and mall portal. MaxIMS fits sellers connecting inventory, location fees, sales, and profitability. Sortly emphasizes visual inventory. Square fits seller-run checkout. Shopify and Vendoo fit stronger ecommerce or cross-listing workflows.

Do I still need an inventory app if my antique mall has a vendor portal?

Possibly. Use the portal for the sales, statement, and payout data the mall controls. A separate app can help track acquisition cost, storage inventory, other selling locations, and expenses the portal does not contain. Test whether the two systems can be reconciled without duplicate work.

Can a reseller inventory app calculate my real profit?

It depends on what the app records and what it means by “profit.” Gross profit may include sale price and item cost but exclude rent, commissions, repairs, mileage, or overhead. Check the formula and plan limits, then compare the result with one real month of statements and expenses.

Should I choose a POS or an inventory app?

Choose a POS when you control checkout and need payments tied to inventory. Choose an inventory app when the mall controls checkout but you still need your own item, cost, location, and reconciliation records. Some sellers use both because the systems answer different questions.
