I really appreciate this reply. I’m going to answer everything, and if we have further conversation, we should start a private message chat because I don’t want to completely overshadow your post about getting more conversions.
How does the 4% commission actually work? Is it on the full order value or just the portion attributed to the negotiated discount?
Just the portion attributed to the negotiated discount. My thinking is that I know Shopify sellers are sick of every app charging a monthly fee. I didn’t want to be like that. I wanted skin in the game. I want our interests to be aligned. I only want to win if you’re winning.
An example: $2000 cart. One product was bought at $1,000 with no discount, the other was originally $1200 but Fluxley gave $200 off. The commission charge is $40 (Only on the portion Fluxley helped with), NOT $80.
Can I control where and when it shows up (for example, only on certain products, only for carts over $3k, or only on exit intent)?
Yes*. The asterisk is because I’m still building the “carts over $3k or only on exit intent.” But you have full control over which products it’s enabled on and the range for each product. It even works for variants.
Can I tightly cap the discount so it never goes past a set limit per product?
Yes, see above. It’s impossible for the discount to go above what you’ve configured.
Does it try to close with the smallest discount possible, or does it jump straight to the max?
It tries to close with the smallest discount possible. Right this second, it has a frustrating tendency to go straight to the max if someone low-balls you (like if they offer $100 for a $1,000 product), which I’m fixing today. But it’s configured and trained to aim for three back and forth messages following this scheme:
- Round 1: 20-30% of max (e.g if $100 off is max, offer $20-$30 off)
- Round 2: 50-65% of max (e.g if $100 off is max, offer $50-$65 off)
- Round 3: 75-90% of max (e.g if $100 off is max, offer $75-$90 off)
If someone offers a deal that’s great for you, (e.g. You were willing to give $200 off, but they only want $50 off), it accepts immediately and enthusiastically.
Can customers negotiate multiple times, or can that be limited so it doesn’t train everyone to expect a deal?
It’s limited by default to two negotiation sessions per product per person per hour. If if someone tries to negotiate a third time, they get a message that they’re not allowed to do that and it doesn’t work for an hour to prevent abuse. I could make that an option too if you wanted to configure how many times someone’s allowed to try before they’re blocked.
Any real examples or data from furniture or other high-ticket brands?
My current highest-ticket item is jewelry. I haven’t gotten permission from my users to share their stores/numbers yet, but generally we are seeing a ~10% conversion rate increase. You would be my first furniture store 
Regarding giving discounts to people who don’t need them
I’m really glad you brought this up, because I’ve been agonizing over it. I’ve been thinking of ways to avoid showing the button to people who don’t need it. Here are some ideas I’ve come up with. I already know how I would implement basically all of them. Let me know if any of these solve your objection. Anything with numbers would be configurable by you.
- Show the button only if the customer has a cart value over $1,000 (you already mentioned this one)
- Show the button only if the customer has been on product page longer than 30 seconds
- Show the button only if it’s the second time the customer has viewed that specific product today
- Show the button only on exit intent (I’m actively working on this one, but it’s a big one)
Farther in the future, I would love to build something like abandoned cart emails. The vision is that the button wouldn’t have to appear anywhere on the page at all, but if a user has an abandoned cart, it would send them an email inviting them to make an offer on their abandoned cart.
I really appreciate you giving me the opportunity to type all this out. Whether or not you go with Fluxley or not, I’m wishing you tons of success :).
Thank you,
