Topic summary

A user is searching for a Shopify custom product options app under $20 that supports:

  • One-time charge options
  • Percentage-based pricing tied to product cost

They’ve tested multiple apps but encountered compatibility issues:

App 1 problems:

  • Custom options don’t work in quick-view modals
  • “Buy Now” button malfunctions, adding entire cart instead of single product
  • Support team declined customization requests

App 2 problems:

  • Discount calculation error: applies discount to (product + option price) instead of applying discount to base product first, then adding one-time charge

The user emphasizes they need an app that allows customizations or modifications to fit their store’s specific requirements.

Response received:
A developer suggests abandoning apps in favor of custom development, arguing that monthly app fees ($20/month = $960 over 4 years) make one-time custom solutions more cost-effective and fully customizable. They offer their services for custom implementation.

Status: Discussion remains open with no app recommendation provided yet.

I have been searching for a custom product options app with the following features:

  • The app price should be under $20.
  • A one-time charge option should be available.
  • Custom options should have a cost based on a percentage of the product price.

I have tried many apps so far, but either they don’t offer percentage-based costs, or they have other compatibility issues.

For example, one of the apps I shortlisted does not allow me to add custom options to my quick-view modal windows. Additionally, this app affects the default “Buy Now” button functionality. Instead of only adding the current product to the checkout page, it adds all the products from the cart. When I contacted their support team, they said they couldn’t make any customizations to address these issues.

Similarly, another app I tried is perfect in almost every way, but it calculates the product discount incorrectly. For a one-time charge, the discount should be applied to the base price of the product first, and then the one-time charge should be added. However, this app applies the discount to the product price + custom option price, which is incorrect.

I’m not saying these apps are not functional, but I was looking for an app where customizations could be made to meet our store’s specific needs. If we need to make changes ourselves, that would be acceptable as well.

Finding a Shopify app that 100% meets your requirements can be challenging. Instead of looking for app you can prefer custom solutions.

Here is Cons of using app.

1: it will cost you monthly charges. Let if a app charge $20/month then it become $960 if you use your store for 4 years.

2: It is likely impossible that one app provide you all requirements.

Of you consider using custom solutions then you have to pay one time to developer like me (I have provide 100+ Shopify app solution with Shopify backend). And you can modify each and everything and surely custom features will fulfill your all requirements.
