Automation is already part of modern resale. The more useful question is which parts of the business are worth automating first, and which tools actually save time.

At 888Lots, we work with B2B resellers sourcing wholesale and liquidation inventory for Amazon, eBay, online stores and retail businesses. For active sellers, the biggest opportunities are usually in sourcing, product research, listing creation, cross-listing, inventory management, shipping, customer service and reporting.

Below are 10 practical reseller automation setups worth testing in 2026.

1. Use Keepa and SellerAmp to Screen Products Before You Buy

For Amazon resellers, one of the easiest improvements is reducing the amount of manual product research required before placing a wholesale order.

Keepa is useful browser extension for checking Amazon price history, sales-rank movement and offer history. Instead of judging an opportunity from the current Amazon price alone, resellers can look at how the product has behaved over time.

SellerAmp SAS goes further by combining profitability calculations, sales rank, FBA and FBM seller counts, price history and sourcing criteria in one product analysis. SellerAmp also supports saved sourcing profiles and advanced searches based on criteria such as rank, price history and stock.

A practical workflow is to set minimum criteria before reviewing inventory. For example, an Amazon FBA buyer might define a minimum ROI, maximum seller count and acceptable sales-rank range.

Then, when reviewing wholesale inventory on 888Lots, the buyer can concentrate on products that meet those criteria instead of researching every SKU equally.

This is especially useful when evaluating large assortments of shoes, clothing wholesale, electronics wholesale or general merchandise.

Useful tools: Keepa, SellerAmp SAS, Amazon Seller Central

2. Create a Wholesale Buying Sheet That Calculates Profit Automatically

Not every useful reseller automation needs specialized software.

Google Sheets or Excel can handle a large part of product screening if the buying sheet is structured correctly.

A useful buying sheet should calculate:

Total Purchase Cost
Wholesale price × quantity

Landed Cost per Unit
Wholesale price + inbound shipping + prep costs + other per-unit costs

Estimated Profit per Unit
Expected selling price − landed cost − marketplace fees − fulfillment or outbound shipping

Profit Margin
Estimated profit ÷ expected selling price

ROI
Estimated profit ÷ landed cost

Total Potential Profit
Estimated profit per unit × quantity

These calculations allow buyers to change one assumption and immediately see how the deal changes.

For larger wholesale purchases, add another column showing how much capital the order requires. A product with attractive margins may still be a poor purchase if the minimum order quantity ties up too much cash.

AI tools such as ChatGPT can also help analyze exported inventory spreadsheets, group products by profitability or identify SKUs that meet specific buying rules.

The key is to automate the screening process without automatically approving purchases.

Useful tools: Google Sheets, Microsoft Excel, ChatGPT, SellerAmp SAS

3. Use eBay Product Research Before Pricing Used or Liquidation Inventory

Amazon data is not enough for every product.

For eBay-focused resellers, eBay Product Research in Seller Hub is useful for checking actual marketplace activity before deciding how to price inventory.

Instead of relying on active listings, compare sold-market information for the same or similar products.

This is particularly useful with:

• footwear
• branded clothing
• discontinued products
• collectibles
• tools
• replacement parts
• open-box goods
• liquidation inventory without a stable Amazon listing

For products that do not have an obvious ASIN or a reliable Amazon reference price, sold-marketplace data can provide a better indication of what buyers are actually paying.

For larger catalogs, tools such as ZIK Analytics can also be used for eBay product and competitor research.

Useful tools: eBay Seller Hub Product Research, ZIK Analytics, Google Lens

4. Generate the First Listing Draft With AI

Creating listings is one of the clearest uses of AI for resellers.

The important part is feeding the tool accurate product information rather than asking it to guess from a product name.

A reseller can provide:

• brand
• model
• UPC or EAN
• ASIN
• size
• color
• condition
• specifications
• marketplace
• target buyer

Then use ChatGPT to prepare the title, product description, key features and marketplace-specific copy.

For eBay sellers, eBay itself also provides AI-assisted listing features through Seller Hub. Current reseller tools increasingly combine bulk listing, AI listing assistance and marketplace management.

For businesses processing hundreds of SKUs, this can also be automated through an API, spreadsheet or workflow platform such as n8n, Make or Zapier.

A practical setup might take a new row from a product database, send the structured product information to an AI model and write the resulting draft back into the listing sheet for review.

That removes most of the repetitive writing without publishing unverified AI content directly to the marketplace.

Useful tools: ChatGPT, eBay Seller Hub, n8n, Make, Zapier

5. Use Vendoo or List Perfectly for Cross-Listing

Resellers selling fashion, footwear, accessories and other one-off inventory often lose a significant amount of time recreating listings across marketplaces.

Vendoo allows sellers to create or import a listing and distribute it across supported marketplaces. Its current US product supports more than 10 marketplaces, including eBay, Poshmark, Mercari, Depop and Facebook Marketplace.

Vendoo also supports importing existing listings and bulk delisting or relisting.

List Perfectly is another established option for cross-listing and inventory management, while Crosslist, Flyp and PrimeLister are alternatives worth comparing based on the marketplaces a reseller actually uses.

The practical tip here is not to select the platform with the longest feature list.

Start with the marketplaces that already produce sales. If most of the business comes from eBay, Poshmark and Depop, choose the tool that handles those three reliably before worrying about ten additional channels.

Useful tools: Vendoo, List Perfectly, Crosslist, Flyp, PrimeLister

6. Automate Stale Inventory Reviews

Older inventory should not sit unnoticed.

A simple inventory report can automatically flag products based on the number of days since they were received or last sold.

For example, create separate views for:

• inventory held for more than 30 days
• inventory held for more than 60 days
• inventory held for more than 90 days
• inventory with no sales during the previous 30 days

From there, different actions can be applied.

A 60-day item may need a price review. A 90-day product may need to be added to another marketplace, included in a promotion or marked for clearance.

Vendoo includes delist and relist functionality that can be useful for refreshing older marketplace listings.

For larger operations, inventory systems such as Cin7, Finale Inventory or Zoho Inventory can provide more structured SKU and warehouse management.

Smaller resellers can achieve much of the same visibility using Google Sheets or Airtable with automated filters and alerts.

Useful tools: Vendoo, Airtable, Google Sheets, Cin7, Finale Inventory, Zoho Inventory

7. Set Up Shipping Rules in ShipStation

Shipping is a good example of a process where a few automation rules can remove dozens of daily decisions.

ShipStation allows sellers to create rules based on order value, destination, SKU, sales channel, tags and other order information. Those rules can automatically select shipping services, package types, insurance settings, users and packing slips.

A reseller could create rules such as:

• orders under a certain weight use USPS Ground Advantage
• heavier domestic orders compare UPS and FedEx
• high-value orders require signature confirmation
• Amazon orders receive one packing-slip format
• eBay orders receive another
• oversized products are routed to a separate packing station

ShipStation can also use rate shopping to compare available carrier services.

Veeqo is another option worth reviewing, particularly for sellers already operating heavily through Amazon.

The main benefit is consistency. Warehouse staff should not have to decide from scratch how every routine order should ship.

Useful tools: ShipStation, Veeqo

8. Use Barcode Scanning Instead of Manual Warehouse Updates

Warehouse automation can begin with a barcode scanner and clearly defined locations.

Each product should have a SKU, and each storage location should have its own identifier.

When inventory arrives, the employee scans the product and its storage location. The same principle can be used during picking and cycle counts.

This greatly reduces problems caused by employees manually entering SKU numbers or relying on memory.

For smaller operations, inexpensive Bluetooth barcode scanners can work with inventory systems or even structured spreadsheets.

Larger sellers can connect scanners to systems such as Finale Inventory, Cin7, Zoho Inventory or a warehouse management system.

Another useful setup is to generate pick lists sorted by warehouse location rather than order number. That reduces unnecessary walking when several orders are being picked at once.

This is where software can produce a direct operational gain without introducing complicated AI.

Useful tools: Finale Inventory, Cin7, Zoho Inventory, barcode scanners

9. Automate the Repetitive Part of Customer Support With Gorgias

Customer support is another area where automation works best when it deals with predictable questions.

Gorgias is built around ecommerce support and currently offers AI-assisted responses, order-related automation and customer self-service. Its AI Agent can handle common order questions and perform actions through connected ecommerce systems.

Useful automations include:

• tracking requests
• order-status questions
• return instructions
• shipping-policy questions
• basic product questions
• ticket classification

For example, an incoming message containing an order number and a tracking question can be matched to the order and answered with the latest available status.

More complicated problems should remain with a human agent.

Other tools worth considering include Zendesk, Re and Freshdesk, depending on the size of the business and where customer messages originate.

Useful tools: Gorgias, Zendesk, Re, Freshdesk

10. Trigger Marketing From Inventory Data With Klaviyo and n8n

The strongest marketing automation for a reseller is usually based on inventory or customer behavior rather than a fixed newsletter calendar.

Klaviyo can create automated flows based on browsing, purchasing and product-level activity. Product-specific flows can react differently depending on what someone viewed, added to cart or purchased.

That opens up much more useful campaigns.

A footwear buyer can receive new shoe inventory without also receiving every electronics promotion.

A reseller who repeatedly buys a certain category can be notified when new products in that category arrive.

A buyer who has not ordered recently can receive a campaign based on what they previously purchased.

For more customized workflows, n8n or Make can connect inventory databases, ecommerce platforms, email systems, spreadsheets and AI tools.

For example, a new inventory upload can trigger a workflow that identifies the product category, prepares a short promotional description and adds the relevant products to a marketing queue.

This is where automation becomes much more useful than simply asking AI to write a social media post.

Useful tools: Klaviyo, n8n, Make, Zapier, ChatGPT

A Practical Reseller Automation Stack

There is no reason to implement 20 tools at once.

A smaller Amazon reseller might start with:

Keepa + SellerAmp + Google Sheets + ShipStation

A multichannel fashion reseller might use:

Vendoo + eBay Seller Hub + Airtable + ShipStation

A larger resale business could combine:

inventory management software + barcode scanning + ShipStation + Gorgias + Klaviyo + n8n

The tools should follow the business model.

An Amazon FBA reseller buying wholesale inventory has very different requirements from someone selling individual vintage products on eBay and Depop.

Where 888Lots Fits Into the Automation Stack

Automation becomes most useful when the sourcing data is good.

At 888Lots, approved B2B buyers can source wholesale and liquidation inventory from our New Jersey warehouse, including branded merchandise across footwear, clothing, electronics, home goods and other categories.

Resellers can use product-level marketplace information while evaluating inventory and use Stock Radar to monitor products they want to source.

From there, external tools can support the rest of the process.

Keepa and SellerAmp can assist with Amazon research. Cross-listing platforms can distribute inventory to additional marketplaces. Inventory software can track the products once they arrive. ShipStation can automate fulfillment, while Gorgias or similar tools can handle repetitive customer-service requests.

That is the real value of reseller business automation: not one AI tool that claims to run the entire business, but a practical set of tools that removes manual work from the parts of resale that can actually be standardized.

The reseller still makes the buying decision.

The software simply makes it possible to research more inventory, list it faster and manage more orders without adding the same amount of manual work.
