AuthCord vs Sell.app vs BillGang: Which Platform Should You Use?
Sell.app and BillGang (formerly Sellpass) are popular platforms for selling digital products online. But if you sell software that needs licensing, HWID protection, or Discord-based access control, they leave major gaps. Here is how they stack up against AuthCord.
What each platform actually does
Sell.app is a digital goods storefront. You create a store, list products, accept payments through Stripe, PayPal, Cash App, Square, or crypto, and deliver files or serial keys to buyers. It handles the checkout flow and nothing else. No licensing, no HWID, no Discord integration beyond basic webhooks.
BillGang (rebranded from Sellpass) is similar but broader. It offers a more mature store builder, subscription support, Telegram and Discord bots for notifications, and more payment plugins. Their free Core tier takes 2.9% + $0.07 per transaction. Their Scale plan at $299/mo removes platform fees entirely. Like Sell.app, BillGang has zero software licensing or authentication capabilities.
AuthCord is a software monetization platform. It handles payments and storefronts like Sell.app and BillGang do, but it also handles everything that happens after the sale: license validation, HWID binding, Discord role sync, verification gates, session management, entitlements, offline tokens, and more. The storefront is one piece of the system, not the whole system.

The real difference
Sell.app and BillGang end at the checkout. Once a customer pays, their job is done. You get a webhook notification and a payment record. What happens next is entirely on you.
With AuthCord, the checkout is just the beginning. When someone buys through your storefront, the platform automatically activates their license, binds their hardware ID, assigns Discord roles, enables their entitlements, and starts tracking their session. No glue code. No manual steps. No separate tools.
If you sell software, this distinction matters. Sell.app and BillGang are great if you sell ebooks, design assets, or one-off digital downloads. But if you sell software that needs access control, anti-piracy protection, and Discord community management, they only solve one piece of the puzzle.
Pricing comparison
| Plan | AuthCord | Sell.app | BillGang |
|---|---|---|---|
| Free tier | Free (5% tx fee) | Free (3% tx fee) | Free (2.9% + $0.07) |
| Paid (low fees) | $11.99/mo (3% tx fee) | $199.99/mo (0% fee) | $299/mo (0% fee) |
| Pro / Scale | $9.99/mo (2% tx fee) | Same plan | Custom enterprise |
| Enterprise | $19.99/mo (1% tx fee) | N/A | Custom |
On pure storefront pricing, Sell.app and BillGang look cheaper on the surface. Their free tiers have lower transaction fees, and if you do enough volume, their flat-rate paid plans eliminate fees entirely.
But this comparison is misleading. Sell.app and BillGang are payment rails only. If you need licensing (like KeyAuth at $5/mo), Discord management (like RestoreCord at $5/mo), and a storefront, you are paying for three separate services. AuthCord bundles all of that into a single subscription.
For software sellers doing under $10,000/mo in revenue, AuthCord's percentage-based fees are almost certainly cheaper than Sell.app's $199/mo or BillGang's $299/mo flat rates. And you get licensing, HWID, and Discord management included.
Payment methods
One area where Sell.app and BillGang have an edge is payment method variety. Both support Cash App, Square, and Paddle (as a merchant of record). AuthCord currently supports Stripe, PayPal, and NowPayments (crypto).
For most software sellers, Stripe + PayPal + crypto covers 95%+ of buyers. But if Cash App or Square is important to your audience, that is a gap to be aware of.
Discord integration
Sell.app has no native Discord integration. You can use their webhook to trigger a bot, but you have to build and host that bot yourself.
BillGang has a basic Discord bot that can post notifications and grant roles on purchase. It is functional but limited. No verification gates, no alt detection, no backup, no migration.
AuthCord treats Discord as a first-class citizen. OAuth verification with captcha, VPN detection, and alt account blocking. Automatic role sync on purchase, expiry, and ban. Server backup and restore. Migration between servers with member re-invite. A full slash command bot for user self-service. Community forums built into the storefront. Enterprise users can even bring their own bot token for full white-label branding.
Who should use what
Use Sell.app if:
- •You sell ebooks, templates, design assets, or one-off digital downloads
- •You need a simple checkout page with no backend
- •You want to embed checkout on an existing website
Use BillGang if:
- •You do high volume and want zero platform fees
- •You need Cash App, Square, or Paddle support
- •You sell serial keys, accounts, or digital goods without licensing needs
Use AuthCord if:
- •You sell software that needs license validation or HWID protection
- •Your community lives on Discord and you need automated role management
- •You want payments, licensing, and community tools in one platform
- •You need entitlements, remote config, or offline validation
- •You want server backup, verification gates, and abuse detection built in
Bottom line
Sell.app and BillGang are good at what they do: processing payments and delivering digital goods. If that is all you need, they work fine.
But if you sell software, you need more than a checkout page. You need licensing, anti-piracy, Discord automation, and a way to manage your users after they buy. Sell.app and BillGang leave all of that to you. AuthCord handles the entire lifecycle from purchase to ongoing access control in one platform.
