About Calculated Prices by Holest

Calculated Prices by Holest Engineering

What can you do with this app?

  • Add additional price parameters to product page
  • Make these parameters conditional and define their display order
  • Define your product or global price modifying formulas (inside formula you have access to product/variant properties, additional parameters values, customer tags, client country, date and time)
  • Add conditional file uploads for product orders
  • Add conditional text inputs for product orders

Idea background

Every serious business has a need for sophisticated pricing policy. Also, some specific product has a variety of properties that customer needs to choose in order of getting the right thing for them in a fully automated way.

Shopify has the very efficient way of deferring product by its variants but in some cases, you need something bit different. For example, if you have some optional feature for a product that increases its price you can just create more variants of product with it included. This is very straightforward, but in some cases, you may be unable to do this because of 100 variant limit. In some cases for certain kinds of products, this can be unpractical.

File uploads

As naturally imposed and commonly needed things along with this kind of features are file uploads and custom text inputs. When a product is highly customizable usually there are options to upload some kind of design, logo and specify some text to be put on product or way of crafting. That's why we also added the ability of uploads and text inputs that are in conjunction with price modifying parameters. Uploads destination is Google drive and that gives you further freedom of implementations.

Common use cases

Price changes imposed by year period or currency fluctuations can sometimes become the harsh burden for you. For example Black Friday lasts for a couple of days. It requires you to do homework twice. You first lower all prices and when it passes you need to return them back. With this app, it is enough to declare shop-wide multiplier and all your prices in front-end will modify instantly. When low-price period passes it is enough to reset this multiplier to 1.

This feature enables you to easily do some other commonly known salesmen maneuvers like “happy hour”. If you sell food, for example, you can easily set a different value of multiplier from 9 PM to 11 PM

Technical notes

Because "Product variant A" is not same as "Product variant A + Engraving" and each can have it's own quantity, this APP has to modify your default shop cart HTML so it could present all added information correctly. Because carts from theme to theme can have different layout we picked standardized nicely looking layout that is flexible for all shops.
