Singleton | Verify Customers vs SpurIT Installment Invoicesfor Shopify (2026)
Singleton | Verify Customers and SpurIT Installment Invoices are both Shopify apps affecting product pricing and customer access, but they serve vastly different purposes. Singleton focuses on access control and customer verification, allowing merchants to gate prices and add-to-cart functionality based on approval. SpurIT, on the other hand, aims to boost sales by enabling customers to pay for purchases in installments, making higher-priced items more accessible. Singleton is best suited for businesses requiring stringent control over who sees their product information and can make purchases, likely due to regulatory requirements, wholesale strategies, or exclusive product offerings. SpurIT targets businesses seeking to increase their average order value and customer loyalty by offering flexible payment options.

Our Verdict
The choice between Singleton | Verify Customers and SpurIT Installment Invoices depends entirely on the merchant's primary need. If the goal is to control access to products and prices, especially for B2B or wholesale operations or those in regulated industries, Singleton is the clear choice. The ability to customize registration forms and manually approve or decline customers offers a high degree of control. However, if the objective is to increase sales by making higher-priced items more affordable and boosting customer loyalty, SpurIT Installment Invoices is the better option.

Common Questions

Based on the description, SpurIT Installment Invoices appears simpler to set up initially, as it focuses on setting up payment plans for products or collections. Singleton requires designing registration forms and configuring approval processes, which could take more time.
Which app has better customer support?
There is no information to determine the quality of customer support for each app from the given data. It is recommended to review customer testimonials and available support channels outside of this comparison to assess this.
Can these apps be used together?
