Quickly calculate your price to end user in one of 2 ways. The resulting sell price will be part of your print screen so you can simply copy and paste to a customer- their tank and price from you. (Either method still privately shows you cost and profit info as well)
1) Margin on Cost:
Add your margin from your cost, and create your selling price on the fly, allowing you to deliver a budget quote on your phone right in front of a client. (It takes list price down to your cost, then divides your cost by the margin inverse factor- proving "true gross margin" for yourself in the sell price, not just a simple "markup")
TIP: Increase this percentage to add in additional fudge factor if more accessories will be needed than the options here allow.
2) Off List (markdown):
This is a simple Markdown from List price. For example: If you enter your buying discount of 40% with us it simply gives your cost. In some cases you may want to do 0 or 10% off list for a more Budget, "budget" number.
