Miss Manners: Potential partner company has typos on its website

Dear Miss Manners: I am to meet with representatives of a company to discuss our hiring them for a project. While reviewing their website, I discovered three typos. I honestly believe they would want to know of these errors, and frankly, as when you notice food in someone's teeth, I have a strong urge to tell them. But I fear that mentioning it at the start of the meeting would get things off on the wrong foot, and mentioning it at the end would leave a sour taste. If we hired them, we would be working closely with them on the project. Suggestions?
