Top 4 Inventory Tracking Methods for Circular Retail and Consignment Shops

Explore the best ways to track inventory in consignment, resale, and branded recommerce stores. From basic spreadsheets to advanced end-to-end consignment and resale software.

Managing inventory in resale and consignment shops is uniquely challenging because every item is different. Unlike traditional retail, where products are standardized and tracked in bulk, resale requires item-level tracking for intake, pricing, payouts, and expiration. Without the right system, stores face errors, chaos, slow processes, unhappy consignors and lost revenue.

This guide walks you through four proven inventory tracking methods, from the simplest to the most advanced. Whether you’re running a single boutique shop or launching a branded resale program across multiple locations, choosing the right method will help you stay organized, reduce workload, and grow profitably.

Paper-Based Tracking

Paper systems are the most basic way to manage resale and consignment inventory. Staff manually log each item in binders or printed intake forms, usually with handwritten tags.

Pros:

  • Very low cost to get started
  • No technical knowledge required
  • Easy to explain to new staff

Cons:

  • High risk of lost tags and errors in payouts
  • Time-consuming to update and reconcile
  • Impossible to scale beyond small volumes

Paper tracking may work for very small shops or one-time events like pop-ups, but it quickly becomes overwhelming as intake grows. Even a single busy sales weekend can create chaos, leading to mismatched payouts and poor customer experiences.

Spreadsheet Tracking

Many shops upgrade from paper to spreadsheets such as Google Sheets or Excel. This allows for more organized tracking of each item’s ID, category, price, and status. Cloud-based spreadsheets make it easier for multiple team members to collaborate in real time.

Advantages:

  • Affordable and simple to set up
  • Cloud-based access for remote management
  • Clear improvement over paper systems

Limitations:

  • Still requires manual updates to stay accurate
  • Easy to make mistakes when copying or editing data
  • Difficult to scale beyond 500 to 1,000 active SKUs
  • No automation for consignor payouts or expiration tracking

Spreadsheets are a good option for smaller stores with limited staff. However, as resale programs grow, spreadsheets quickly become inefficient and error-prone. They don’t provide real-time visibility or advanced features like pricing optimization.

Integrated Retail Systems

Some retailers use large, integrated systems like NetSuite or Lightspeed to manage their entire operation, including inventory, point-of-sale, accounting, and customer relationship management. These systems are powerful for traditional retail but are not built specifically for resale, where every item is unique.

Advantages:

  • Connects multiple parts of the business in one system
  • Good for multi-location operations and standard retail inventory
  • Provides a single source of truth for data

Challenges for resale:

  • Limited support for single-SKU tracking
  • No built-in consignor splits and payouts or item expiration handling
  • Customization is complex and expensive

Integrated systems are helpful for retailers running both new and secondhand sales, but they often require a specialized resale platform to handle the complexity of consignment and circular inventory.

Consignment Software

Dedicated consignment software is designed to handle the specific needs of resale and circular retail. This is the modern, state-of-the-art solution for shops and brands that want to scale efficiently. Platforms like Circular provide automation, accuracy, and insights that older methods cannot match.

Core features of modern consignment software:

  • Automated intake and inventory updates
  • Real-time stock visibility across one or multiple stores
  • Seller portals for seamless intake scheduling and transparency
  • Integrated consignor splits and payout tracking, eliminating manual calculations
  • POS integrations with tools like Shopify, Zettle, and Extenda GO
  • AI-powered pricing to optimize sell-through rate and profitability
  • Sustainability tracking showing CO₂ and water savings per item
  • Marketplace-ready architecture for future online expansion

Why it matters:

When inventory is tracked manually, staff spend countless hours on admin tasks instead of customer service. Errors in pricing, payouts, or item expiration hurt both the business and consignors. Consignment software like Circular automates these workflows, saving 50-70% of staff time while increasing accuracy and revenue.

For growing resale programs, software is essential. It makes it possible to scale without adding endless manual work and creates a seamless experience for both staff and customers.

When to Upgrade Your System

If your store handles fewer than 500 active items, spreadsheets may be sufficient in the short term. But as intake grows or you expand to multiple locations, upgrading to specialized software becomes necessary.

A good rule of thumb:

  • If your team spends more time updating spreadsheets than serving customers, it’s time to automate.
  • If you’ve hit 500+ active SKUs, consignment software quickly pays for itself through efficiency gains.
  • If you’re planning to expand resale across several locations or brands, end-to-end software is the only viable option.

The Circular Advantage

Circular is built specifically for apparel resale and branded recommerce. It combines everything a modern resale business needs in one platform, from intake and seller portals to POS integrations and sustainability reporting.

What sets Circular apart:

  • AI-powered pricing models that learn from your store’s data

  • Seamless integration with existing POS systems
  • Sustainability reporting to show impact per item sold
  • Designed for both local stores and global branded resale programs

By automating manual tasks and providing real-time insights, Circular helps retailers and brands transform resale into a profitable, scalable business model.

Conclusion

Every inventory tracking method has its place, from paper systems for small pop-ups to advanced consignment software for large, multi-location programs. But as resale grows, automation and precision become critical for success.
