Enhance: VAT Dual Prices B2B vs Function Labfor Shopify (2026)
Enhance: VAT Dual Prices B2B and Function Lab cater to vastly different needs within the Shopify pricing category. Enhance: VAT Dual Prices B2B is explicitly designed for merchants, particularly those operating in B2B and B2C environments, that need to display prices both inclusive and exclusive of VAT. Its primary strength lies in its ease of use for configuring and customizing how these dual prices are shown, offering granular control over tax rules based on country, product, and customer tags. This app focuses on providing clarity to customers regarding pricing by eliminating confusion caused by VAT.

Our Verdict
Enhance: VAT Dual Prices B2B is the clear choice for merchants who need a straightforward solution for displaying VAT inclusive and exclusive prices, especially if they cater to both B2B and B2C customers. Its ease of use and focus on clarity make it accessible even for merchants without technical expertise.
Function Lab is best suited for technically skilled merchants or those with access to developers who want to deeply customize their discount logic. The JSON editor provides a powerful tool for creating complex discount rules, but it demands a level of technical competence that many merchants may not possess. The promised future features, if delivered effectively, could broaden Function Lab's appeal to those needing customization beyond discounts, however, at the time of review, only automatic discounts are available.
Common Questions
Which app is easier to set up and use?
Enhance: VAT Dual Prices B2B is significantly easier to set up and use, offering a user-friendly interface for configuring display options without requiring any coding. Function Lab requires knowledge of JSON and function writing, making it less accessible to non-technical users.
Can I use these apps if I only sell to B2C customers?
While Enhance: VAT Dual Prices B2B is designed with both B2B and B2C in mind, it's most relevant if your pricing strategy involves VAT and you need to display it clearly. Function Lab's discount functionality is relevant to any business, including those that only sell to B2C customers, if those discounts need custom coding.
Does Function Lab replace other discount apps?
Function Lab is positioned as a way to replace discount scripts with functions, potentially reducing reliance on other apps for complex discount logic. However, it requires technical expertise to implement effectively. It is aimed at creating highly customized discounts rather than offering a broad spectrum of pre-built discount types.
Which app offers better support for multiple currencies?
Neither app explicitly mentions support for multiple currencies in their descriptions. The feature sets do not seem to be related in this regard. It's best to contact the app developers directly to confirm currency support if this is a critical requirement.
If I want to offer location-based discounts, which app is better?
Function Lab, with its ability to create custom functions, *could* be used to create location-based discounts, but it would require significant coding effort. Enhance: VAT Dual Prices B2B does allow you to set tax rates based on selected countries, which might be a suitable alternative if you simply want to display tax differently based on location.
