Proposals
While the number of proposals per month will depend on the package you choose with both, Better Proposals still takes this round. That said, both ConnectWise Sell and Better Proposals will let you customize your templates, but there's a catch. In order to have a template to customize to begin with, you'll have to create one from scratch if you decide on ConnectWise Sell. Better Proposals, on the other hand, offers you more than 260 pre-made templates that you can make your own within minutes.
If you're thinking there's more to a good proposal than design, you're absolutely right. That's why both ConnectWise Sell and Better Proposals offer proposal analytics. For you, this means you'll see which proposals have been received, opened, and signed in one interface. However, unlike Better Proposals, ConnectWise Sell doesn't offer this feature on all plans. Instead, you'll have to have at least the Standard plan to easily check the state of your proposals. Another plus of Better Proposals is the document tracking and notification feature. Simply put, instead of having to check your analytics manually, you'll get notified as soon as a client acts on your document.
