WorkGuru has an incredibly powerful Quoting tool. 

The quote feature in WorkGuru is straightforward to use, and has the support of quote templates that can be applied to a Quote to ensure your quoting process is simplified across your business. 

Quotes can be used for both "do & charge" projects, as well as fixed price projects as well. 

Once a quote is approved by the customer, you can easily accept the quote and turn this into a project in WorkGuru.
