Buyer guides

For buyers about to pay for something they haven't run yet

What to check before buying a ready-made app, website or tool

A checklist for buying something already built: what the preview proves, what is not included, what you must do yourself, and what happens if it disappoints.

3 min readReviewed 18 Sept 2026

The appeal of buying something already built is obvious: weeks of work for a fixed price. The risk is equally simple — you're paying for something you haven't run yet, on the strength of a page written by the person selling it. These are the things worth five minutes before you pay.

1. Find out what the preview actually proves

A video proves a feature existed on the day it was recorded. A working demo proves the code runs today. They're not the same evidence, so on LaunchStock every preview carries a label saying which it is:

Live demo
A working preview of the real product, hosted by the seller.
Sandbox demo
Sandbox demo with test data — may reset periodically.
Sample preview
Preview a sample of the actual files before you buy.
Embedded preview
An interactive preview embedded by the seller.
Video walkthrough
A recorded walkthrough — not an interactive demo.
Simulation only
A simulated experience — not the live product.
Playable demo
The real game, playable here in your browser.
Audio preview
Listen to the actual files before you buy.

If the preview is a video or a set of screenshots, the honest conclusion is that you haven't seen it run. Ask the seller for a live walkthrough before paying rather than after.

2. Read what's not included

The 'what's included' list is the seller's pitch; the 'not included' list is where the surprises are. Hosting, domains, paid API keys, stock images, ongoing subscriptions and app-store fees are the usual ones, and any of them can cost more over a year than the product did.

3. Work out what you'll have to do yourself

Check the requirements and the setup difficulty, and be honest about which side of them you're on. A product that needs Node.js, a database and a deployment platform is a weekend for someone who's done it before, and a wall for someone who hasn't. If there's a setup guide in the package, the listing will say so.

4. Check who's selling it

Every listing on LaunchStock is reviewed before it goes live, and sellers can complete verification — where a person confirms who's behind the account — which shows as a verified badge. Verification confirms identity, not quality, so it's a floor and not a recommendation.

5. Read the licence and the refund policy on that listing

The licence decides what you may build with it, and the refund policy decides what happens if it isn't what the page said. Most listings use LaunchStock's standard policy: a refund if the product is materially not as described, requested from the purchase in your library, with the seller answering first and LaunchStock deciding if you aren't satisfied. Approved refunds reach your original payment method in about 5–10 business days. Changing your mind isn't a reason, which cuts both ways and is worth knowing before you pay.

6. Know what happens after payment

  • You get the files straight away, in your library, along with the licence terms as they stood when you paid.
  • Updates from the seller reach you as new versions once LaunchStock has approved them.
  • Support is whatever the listing promises — some include a period of help, some include none.
  • Anything broken is a support request first and a refund request second; both start from the purchase itself.

The five-minute version

  • What kind of preview is it, and have I seen the thing run?
  • What's on the not-included list, and what will that cost me?
  • Can I meet the requirements without help?
  • Does the licence cover the work I actually plan to do?
  • If it isn't as described, what does this listing's refund policy say?

Questions people ask

Can I try a product before I buy it?
Where the seller offers a preview, yes — and its label tells you what kind it is, from a live demo you can use to a recorded video. Not every listing has one, and a listing without a working demo is one to ask questions about.
What do I get immediately after paying?
The delivery package in your library, with the licence, refund policy and support terms as they stood at the moment you paid.
What if the product doesn't work as described?
Raise it from the purchase in your library. The seller responds first; if you aren't satisfied with their answer, LaunchStock decides. If a refund is approved, your licence ends.
Do I get updates after I buy?
When a seller ships a new version and LaunchStock approves it, it appears against your purchase. What you bought stays available too, so an update can't take away the version you paid for.
