You can set volume pricing for products on the product overview page (accessible by editing the product).
There are two different types of volume pricing: Volume and Tiered. The type of volume pricing can be set by the drop down directly under the Save link.
With straight volume pricing, the price of the product is a straight lookup by quantity. So, in the example below, if the qty of the product on the quote is 11, the price of the product is $10,000*.70 = $7000 and the price of 11 products would be 11*$7000 = $77,000.
If tiered pricing were selected, then price of 11 products would be as follows:
4*$10,000 + 5*$7500 + 2*$7000 = $91,500.
You can specify the Unit Price in terms of an absolute price ($Fixed), a fixed discount amount (-$Fixed Discount), or a percentage discount amount (-% Percentage Discount).
For % Percentage Discount, you have the option of checking the box for Include Options. Checking this box will specify that not only the product base price will be discounted by the %, but also the product option prices will also be discounted by the same %.
Simply click the pencil icon on the Volume Pricing widget and add as many rows as needed. Use the trash icon to delete rows. Be sure to click Save when done.
This pricing will be automatically applied when entering a product and quantity in the quote table of a proposal.
For products subject to multiple price modifications, this is the order the price modifications will be applied:
Price List first
Volume pricing next
Product Option modifications next
