" It is impossible for any company, even yours, to be better or best at everything"

"you need to keep in mind that differentiation does not always work in your favor. Put down the rose-colored glasses and be honest about how well your features perform against competitors.
...
There is no such thing as "better" without "worse," and there is no 'best" without a "worst." It is impossible for any company, even yours, to be better or best at everything. That is tantamount to saying you are perfect, and I don't know of a single B2B market where that is a credible argument. You have to account for the things you are less good at. Focus on finding the positive, but recognize the negative.
...
think of differentiation in three ways: "nice to have," "must have," and "true." It is the true differentiation that ultimately wins you the business.

Competitive prices are also a must-have, but don't fall into the perception trap that so many suppliers fall prey to and that so many purchasing departments encourage. A competitive price is not synonymous with a low price. It is the right price for the right value you deliver."
