I’ve had the best success with easy to digest “competitive battlecards” for sales. The simpler, the better. They should give basic company info, pricing, and how to handle objections. For larger sales teams, these are a great reference point for them to use on the phone.
The ultimate goal of the battlecards should be for any salesperson - new or experienced - to be able to quickly articulate how you are different from the competition. If it doesn’t meet that goal, you’ve missed the mark.
The design of this is important. I’ve used a Google doc with a grid and also a vertical PPT slide - it depends on what your company is most familiar with. I would try to update these at least once a quarter.
Scrappy tip: If you’re in a pinch for time, use a service like UpWork to do the data entry for you - you create the framework, and they fill in the rest. For 5 competitors it should be no more than $100 if you pick a good freelancer.
