Some of our customers create unique discount codes for their partners and then create custom reports in Better Reports to track the sale of each code.
You can even set it up to calculate % commission automatically and send automatic emails to your partners that list all their sales and total commission.
Feel free to reach out to me at firstname.lastname@example.org to discuss further.
Hi! Our app does exactly that. It's a free referral program app Talkable Referrals.
It's very easy to launch. A widget will appear on every page of your site, including your post-purchase window. Customers will be able to share a link to your site through email or social media. Your customer's friend will get an email/message with an offer, and both your customer and their friend will be rewarded a discount once the friend makes a purchase.
Let me know if you need help!
