I use The Customer Factor. I paid for the yearly subscription because I had enough work to take care of it. It has a ton of features that present you as a professional at whatever service-based industry you’re in. You can add customers through the app, and then send estimates right on the spot. It will notify you when the estimate was opened, so you’re not sitting there wondering if they’ve even looked at it. You can set up personal reminders that get sent out to the customers after so many days. If you are interested in a big job,…you can send out a “Big Proposal” that’s more custom and professional than the typical lawn care maintenance estimate. You can track “ALL” of your time, schedule jobs, set job frequency, itemize individual line item prices or one total price on your estimates,…send invoices when jobs are completed, track expenses, tracks your income and unpaid invoices. If you have a customer that decides that they want to write a negative review,…it’ll hide those from being seen on Google. These are just a few of the features that this CRM software has. It’s easy for you to incorporate other services with it, if you’d like. You can always give it a go and pay $45/month to see if you really like it.
