Is your yard taking off? Use Builds site list to order services and materials. The site list collects all the items and resources you need according to your estimate. Do you especially want to stock up on supplies? Then you can also enter orders based on your stock lists. Moreover, Build-Software always allows you to change your order request, e.g. if you decide to perform certain items yourself after all instead of using a subcontractor or vice versa.
Once you get the prices from your subcontractor or supplier, use the data from your yard or stock lists to easily create a detailed purchase order with the necessary clauses to get a full document.
