Is there an option to have customers price list?

Let me share some details about customizing price lists in QuickBooks Online (QBO), HKS2019.

In QBO, we can set pricing rules for specific products and services where you can offer discounts or charge different rates by item. The Price Rules is still on Beta pace which means only selected customers can turn it on. This option is unavailable in QBO Simple Start and Essentials. To utilize this, let's turn it on first by following the instructions below: 

1. Go to the Gear icon on the top menu.
2. Choose Account and Settings.
3. Select the Sales tab.
4. In the Products and services section, select Edit ✎.
5. Select the Turn on price rules Beta checkmark.
6. Click Save and then Done.

After that, we can create a price rule by following the steps outlined below:

1. Go to the Gear icon again and select All lists.
2. Choose Price Rules and enter a unique name in the box.
3. In the Product and services drop-down, pick All inventory.
4. Pick Percentage in the Price adjustment method field.
5. Select Increase by and enter the % amount in the Percentage field.
6. Pick a Start and End date, then click Apply rule.
7. Hit Save and close.

@HKS2019, @RCV may have already answered your question. If not, then at this time there wouldn't be a solution for you within QBO. You would need an alternate app to handle this for you.
