Always always always ask for Pinterest Management testimonials, sooner than you think you should.
You’re doing amazing work for your clients (or if you’re a new Pinterest Manager, you will be) and you want to share that proof with other potential leads. You also want to make sure that your potential clients can see that other business owners have enjoyed working with you and found your service worth investing in. The best way to do that is to ask for a testimonial sooner rather than later.
