npx skills add sentinelcore/roblox-skills --skill roblox-monetization
End-to-end guide for earning Robux legitimately through Roblox's monetization systems. Covers dashboard configuration and Lua scripting for both developers and designers.
| System | Use For | Repeatable? | Min Price |
|---|---|---|---|
| Game Pass | Permanent perks/access | No (one-time) | 1 Robux |
| Developer Product | Consumables, currency, boosts | Yes (unlimited) | 1 Robux |
| UGC Item | Avatar marketplace sales | N/A | 1 Robux |
| Premium Payout | Passive playtime income | Automatic | No setup |
One-time purchases granting permanent perks. Player pays once per game per pass.
Always run on server (Script), never LocalScript — client-side ownership checks can be spoofed.
Repeatable purchases — players can buy unlimited times. Use for coins, potions, boosts, in-game currency.
Critical rules for
ProcessReceipt:
- Must return
PurchaseGrantedorNotProcessedYet— never error silently- Persist to DataStore before returning — crashes can cause loss
- Return
NotProcessedYeton DataStore failure so Roblox retries the receipt- Only one
ProcessReceipthandler allowed per server; combine all product IDs inside it- Roblox may call
ProcessReceiptmore than once for the same purchase — usereceiptInfo.PurchaseIdas a dedup key if double-granting is a concern
Sell clothing, accessories, and bundles in the Roblox Marketplace.
| Item Type | Creator Cut |
|---|---|
| Clothing (t-shirts, shirts, pants) | 70% of sale |
| UGC Accessories | 30% (40% with Premium subscription) |
| Limited UGC with resale | Up to 70% |
After granting a product server-side, notify the client via a RemoteEvent so the UI can update (show a boost timer, unlock a button, etc.):
Passive Robux from Roblox Premium subscribers spending time in your game. No setup required.
Eligibility requirements:
Steps:
Tipalti: You must create and verify a Tipalti account separately before your first payout. Set this up early to avoid delays.
| Mistake | Fix |
|---|---|
| Ownership check in LocalScript | Move to server Script — client checks can be exploited |
ProcessReceipt throws an error | Wrap logic in pcall; always return a decision enum |
| Not saving purchase to DataStore | Player loses item on crash — persist before returning PurchaseGranted |
Multiple ProcessReceipt handlers | Only one allowed per server — combine all product logic in one function |
| Double-granting on receipt retry | Use receiptInfo.PurchaseId as a DataStore key to detect already-processed receipts |
| Selling UGC without program access | Apply to UGC program first; uploads will be rejected otherwise |
| Price below platform minimum | Minimum is 1 Robux for most item types |
| DevEx blocked despite enough Robux | Check all eligibility: age 13+, verified email, no violations, Premium subscription, earned (not purchased) Robux |
