When building your estimate, there are a few different approaches that you might take when considering how much detail you should include for each cost that you add.
The level of detail is, of course, completely up to you, but here are some examples that might give you an idea of different ways that you might use cost lines to capture your costs:
A one-liner for entering quotes or costs that are being calculated outside of CoConstruct
This is the most basic way that you can use cost lines, and you may find that a vast majority of your specifications and selections may be captured with these "one-liners".
This may be simply entering in a cost from a quote that you received or a similar cost that was calculated outside of CoConstruct.
Simply enter a description for the cost and leave the default "1 each" in place.
Enter your cost in the "Unit Cost", add an accounting code, and you're all set.
A per-unit cost
For things like flooring, tile, or framing, you may know the cost per unit area or length. In these cases, you can enter the unit cost and the quantity in order to come up with the overall cost.
Simply give a description to each cost that you're entering, and use the fields for "Quantity", "Units", and "Unit Cost". The costs will be calculated to determine the "Extended Cost" by multiplying your quantity by the unit cost.
"Sticks and bricks"
If you want to, you can break your estimates down to a very fine, item by item level of detail. As a result, you might be entering costs for each individual component and letting CoConstruct add all of those together for you.
In the example below, costs for individual items were entered, with the total calculated for each line (based on the quantity and unit cost).
The total is also calculated for the overall "16.02 Interior Trim" selection item, with a total extended cost of $5,506.12.
