Singleton | Advanced Discounts vs WBL ‑ Custom Fees (POS)for Shopify (2026)
Singleton | Advanced Discounts and WBL ‑ Custom Fees (POS) are both Shopify apps listed in the "Pricing - Other" category, but they serve entirely different functions. Singleton focuses on incentivizing sales through customizable discounts applied to products, shipping, or cart totals, offering features like volume discounts, targeted offers for specific customer groups (wholesale, B2B), and visual sale highlights. In contrast, WBL ‑ Custom Fees (POS) is designed for physical retail environments using Shopify POS, enabling merchants to add custom fees like delivery or handling charges directly at the point of sale. The primary distinction lies in their application: Singleton aims to boost online sales through strategic discounts, while WBL aims to manage additional charges at the physical point of sale. Singleton is more suited for e-commerce businesses looking to increase sales volume and average order value via promotions. WBL caters to brick-and-mortar stores needing flexibility in applying custom fees to transactions, offering clear and transparent charges managed through the Shopify POS system. The difference in ratings (5/5 for Singleton vs 0/5 for WBL) and review count (31 for Singleton vs 0 for WBL) suggest Singleton has been tested more and received positive feedback, though WBL's lack of reviews might simply mean it is newer and less widely adopted.
