Circulaire ‑ Pre‑owned pricing vs Singleton | Verify Customersfor Shopify (2026)
Circulaire - Pre-owned pricing and Singleton | Verify Customers are both Shopify apps listed under the 'Pricing' category, but they serve fundamentally different purposes. Circulaire focuses on automating the pricing of pre-owned inventory using AI and real-time market data. Its strength lies in providing data-driven valuations, saving merchants time on manual research. The target audience for Circulaire is merchants who sell second-hand goods and want to optimize their pricing strategy. In contrast, Singleton | Verify Customers is a customer management tool that allows merchants to control access to pricing and product information based on customer approval. Singleton's strength is in providing a secure and controlled shopping environment, particularly useful for businesses selling to specific clienteles (e.g., wholesale, B2B). It achieves this by enabling customer verification and the ability to hide prices and 'Add to Cart' buttons from unapproved users. The core difference lies in their focus: Circulaire optimizes product pricing, while Singleton controls customer access to pricing and product information. The apps are suited to entirely different business models.

Our Verdict
Choosing between Circulaire and Singleton depends entirely on the merchant's needs. If the primary goal is to optimize pricing for a pre-owned goods business, Circulaire is the clear choice, assuming the AI pricing suggestions are accurate and reliable. The lack of reviews is a significant risk, however.
Conversely, if the merchant needs to control access to pricing and product information for specific customer segments (e.g., wholesale, members-only stores), Singleton is the more suitable option. Its high rating and numerous reviews suggest a reliable and well-received app for customer management. For most Shopify stores, Singleton is the more appealing choice, as customer management and validation is a more universal requirement than advanced pricing for second-hand goods.
