Billoop vs Chargebee: Open Source vs Subscription

OneTimeSuite Blog · Published 2026-07-21

Billoop and Chargebee solve the same problem from opposite directions: one is source-available software you can own outright for $49, the other is a subscription at $599+/mo run entirely on someone else's servers.

Head to head

What Billoop does well

• BYO Stripe (optional) — Drop in your own API key and plans become Stripe products, customers sync and the portal wraps Stripe's billing portal; without a key it runs the full engine in local mode, and it never touches funds.
• Plans, trials, coupons — Monthly and yearly plans, trial periods and percent or amount coupons (once or forever), all in integer cents, never floats.
• Real proration — Mid-cycle plan changes credit the unused fraction of the old plan and charge the same fraction of the new one as explicit line items, covered by exact-figure tests.
• Dunning that finishes — A failed payment triggers a templated email sequence at +0/+3/+7 days, then auto-cancels or auto-pauses after N attempts, and every send is logged.

What Chargebee still does better

There's a real reason Chargebee costs what it does: a bigger team, broader integrations and dedicated support behind it. If that ecosystem is genuinely what you need, it's worth paying for.

Which one should you pick

If your workflow depends on Chargebee's specific integrations or you'd rather not run anything yourself, stay put — that's a legitimate call. If you're comfortable owning the tool and want to stop paying $599+/mo for a job your own hardware can do, Billoop pays for itself and then some: billoop costs less than a single day of Chargebee's starter tier, and never skims your revenue.
