FAQ
Straight answers.
Will it post reviews for me?
No. Customers leave reviews themselves on your review page. We only record what they actually tell you.
Can I hide a testimonial?
Yes. Only testimonials you approve, with the customer's permission, appear on your site.
How do referral codes work?
Each code is single-use. When a new customer uses it, you mark it redeemed and record who used it.
