It's a common requirement for small business and freelancers to send estimates to their clients. ClientWide has made it really easy to quickly generate these for you. Estimates and Invoices go hand-in-hand with Billable Items, so please make yourself familiar with them if needs be.
Before creating any estimates, please make sure you first have a client and a job associated to the client. You won't be able to create an invoice without these two key items.
