After creating a quote (instructions on how to create a quote can be found here), multiple products or a single product can be presented in the proposal. 

Tick the boxes next to each quote to compare in the proposal. Up to 3 products can be selected to include in a standard proposal. The selected products will appear under the proposal tab.

When the desired products have been selected, click Download Proposal.

The proposal will download as a .PDF file to your device. 

Proposals can also be downloaded when previewing or emailing proposals from the platform.
