"Strong Sales Tool"
What do you like best about Proton?

This software is fantastic for upselling. It is a quick and efficient way to get more products in front of your customers. I like that you can run campaigns on items you want to focus on pitching. It's also great to see the Leaderboard results page as it encourages you and your team to keep using the tool to gain even more sales.

What do you dislike about Proton?

I want the software to pull in-stock items to the top of the list when I search for products by product name.

What problems is Proton solving and how is that benefiting you?

I can quickly find products to upsell that correspond to the customer's business needs which increases the probability of the customer purchasing from us.

"Great Way To Involve Everyone In Moving Sales"
What do you like best about Proton?

Proton's user-friendly system makes pitching new or previously purchased items a breeze. With little interruption or time away from our original processes.

What do you dislike about Proton?

The only thing that I can think of it's a different system that we have to access seperately. So, it's an additional step to have to implement. However, we have started using Proton to search out a customer's account. We've found that the search within Proton is better than our regular system search.

What problems is Proton solving and how is that benefiting you?

We have increased our sales and also, now able offer additional products to every interaction that we have with the customer. It allows us to take advantage of each time we are in contact with the customer.

This program excels at upselling. More items may be presented to your consumers quickly and effectively in this way. I appreciate that campaigns may be created for certain products you wish to market. A nice feature of the program is the Leaderboard results page, which motivates you and your team to keep utilizing it to increase sales.

What do you dislike about Proton?

The loading of the extra selections might be sluggish at times, and I find the button that automatically recommends the chosen goods to be useless.

What problems is Proton solving and how is that benefiting you?

The advantages include being able to quickly check a customer's account to see what things they've recently purchased or priced, as well as being able to provide them a helpful list of stuff!
