Shopify and Lemonstand handle your product pricing structure a little differently. I’ll explain.
Shopify has fields to input Price, Compare at Price, and Taxes (On/Off).
Price is what the customer pays.
Compare at Price is the “normal” or “retail” price. It’s up to your specific theme how that is displayed, but typically the Compare at Price is displayed
slashed through with the Price next to it. This is essentially how you put individual products on sale with Shopify.
Charge taxes on this product is a yes/no checkbox. Shopify only lets you turn tax on or off for specific products, whereas Lemonstand allows you to setup Tax Classes (click to read more about that) which you can use to specify specific tax rates, or no taxes at all, for entire groups of products.
Lemonstand has fields to input Base Price, Tax Class, Cost, On Sale (yes/no), Sale Price or Discount (if item is marked On Sale), and Volume Pricing options.
Base Price is either what the customer pays, or the “retail price” of an item if it’s on sale.
Tax Class is a set of rules which LemonStand uses to calculate tax amounts for a specific product. Using tax classes you can define tax rates for a specific country, state, or ZIP code / city if required. You can also have tax classes setup for Services which no taxes are charged, or specific products where taxes are included in the price.
Cost field is where you can optionally insert the cost of the item which is used for reports.
On Sale toggle lets you mark whether that specific item is on sale. If checked, a separate field appears called Sale Price or Discount where you can indicate whether the product is $5 off or 10% off (or whatever).
Volume Pricing lets you set discounted prices based on the quantity purchased. You can have separate volume pricing for any customer group. For example, any customer may be entitled to 10% off 20 shirts or more, but registered users get 20% off 20 shirts or more.
Here’s another example of volume pricing in action (or you can click that link to read more about it).
Lemonstand wins for having more product pricing options. In my opinion, it makes more sense to have the Base Price remain the same and to enter a separate Sale Price (on Lemonstand) than it does to change the Price to the Sale Price and re-enter the normal price under Compare at price (on Shopify). Although I guess you’re doing the same thing.
Volume pricing, tax classes, and a cost field are other great built-in features that Lemonstand offers. You can do some of those things with Apps on Shopify but they are not available out-of-the-box.
