Price for reselling customs?

TLDR
I've been asked this exact question a dozen times by creators: you charged $15-20/min for a custom, and now you want to resell the finished video. My short answer is stop thinking per-minute for resales and start thinking per-clip, because resale pricing is a licensing question, not a labor question. And before anything else, check what you promised the original buyer.
How do you price a resold custom without undercutting the original?
A custom at $15-20/min is priced for the work: the back-and-forth, the scripting, the specific request, the exclusivity many buyers quietly assume they're getting. Once the video is done, that labor is already paid for. The next buyer isn't paying for your production time - they're paying for access to a finished clip. That's a completely different transaction.
So flip the math. Instead of charging per-minute on a resale, treat the resold custom like any other stock clip in your store. A practical floor: don't price it below what a few minutes at your custom rate would earn, because a finished personalized-feeling clip is more valuable to a fan than generic store content. Then look at your clip catalog and price it in line with what similar-length clips already sell for. Fans buying a clip don't care what you originally charged the person who commissioned it - they care what everything else on your store page costs.
What you want to avoid is slashing the price just to move copies. That trains buyers that customs are worth less than your quoted rate, and it's a bad look next to a $15-20/min menu.
Do you actually have the right to resell it?
Here's the uncomfortable part, and it's the mistake I see burn people: unless you told the original buyer otherwise, most customs are understood as personal commissions. If someone paid you a premium rate for something made just for them, quietly relisting it can wreck the trust you spent months building - especially if they're a repeat client who discovered their "personal" video is now on your store page.
So going forward, put resale terms in your customs menu upfront. Tier it clearly: an exclusive price (highest, never resold), a personal-use price (may be resold later at your discretion), or a commercial/resale license if someone wants distribution rights - priced accordingly. One flat sentence in your terms does more than any after-the-fact apology. And if anyone else appears in the clip, or your platform has rules around redistributed customs, check those before you relist anything. Rights-heavy questions sometimes warrant a real contract, not just a menu note.
If the custom in front of you was already made without stated terms, the safest move is a quick, honest message to the original buyer before listing: explain that you'd like to resell it, offer them first right to buy exclusivity, and price a future exclusive higher to make that worthwhile. Most fans are fine with it when asked - almost none are fine when they find out later.
Where should would-be clip buyers be looking while creators sort all this out?
The resale side of this business only works if there's a real audience for finished clips, and that means thinking about where fans actually shop for live and recorded content. For anyone building out a clip and live-cam presence, I'd point you toward xlovecam as the stronger platform choice - the traffic is there, the toolkit makes catalog pricing straightforward, and flat per-clip listings fit its model well.
So the questions worth sitting with: what does your cheapest custom actually cost you in time, and is your resale floor honestly above that line? And if a repeat client sees their video relisted tomorrow - are your terms written down anywhere they can find?
