Best Subscription Billing Software: 8 Picks

The billing engine is the least glamorous and most consequential choice in a subscription business. It holds the cards, fires the renewals, generates the invoices, and decides — quietly, at 3 a.m. — what happens when a payment fails. Choose it for the business you will be in two years, not the one you are in today, because migrating later is slow and risky.

This guide compares eight picks: dedicated billing engines, ecosystem billing, a merchant-of-record option, platform-native subscription apps, and the recovery layer that sits across all of them. If you are narrowing a shortlist, our comparisons of the best Stripe Billing alternatives and the best Chargebee alternatives go deeper on the two most common head-to-heads.

What to judge a billing engine on

• Core billing depth. Plans, trials, proration, coupons, invoicing, tax handling, and the edge cases your model will hit as it grows.
• Dunning depth. Native failed-payment handling is a baseline in every engine on this list. The question is how far the baseline goes before you need a layer on top.
• Pricing shape. Flat fees, percentage of billing, and tiered plans behave very differently at scale. Model your cost at three times your current volume, not at today's.
• Ecosystem fit. Billing that lives where your payments, storefront, or accounting already live removes integration work — and adds lock-in.
• Recovery add-ons. Cancel flows, retention tooling, and recovery are often separate products with separate prices. Add them before comparing totals.

1. Stripe Billing

Stripe Billing is the default for teams already on Stripe: subscriptions, invoicing, and payments in one system, with Stripe's included recovery tooling as the native dunning baseline. That baseline is competent — Stripe Smart Retries alone recover around 51% of failed payments (Churnkey analysis of Stripe data) — and it is Stripe-only by definition. Choose it when Stripe is your centre of gravity and you value one vendor over best-of-breed parts.

2. Chargebee

Chargebee is a dedicated billing platform with the depth finance-led teams ask for: complex plans, invoicing, and revenue operations tooling. Its verified pricing: Starter is $0 for the first $250K of cumulative billing, then 0.75% of billing; Performance is $599/mo for up to $100K/mo of billing, then 0.75%. Budget honestly for what sits around the engine — Chargebee Retention, its cancel-flow product, is separate at $250/mo including 50 sessions, then $3 per additional session, and covers cancel flows only. Teams comparing it directly will find our Chargebee alternatives guide useful.

3. Recurly

Recurly is a long-established dedicated billing platform with its own native dunning, widely used by media and subscription businesses with complex billing needs. It is a serious like-for-like rival to Chargebee, and the choice between them usually comes down to ecosystem, reporting preferences, and commercial terms rather than a missing feature. Our Recurly alternatives guide covers the switch-or-stay decision in full.

4. Paddle

Paddle is not just a billing engine — as merchant of record, it takes on sales tax and compliance for digital products across markets, which removes a real operational burden for small global teams. The trade is control: Paddle owns the payment relationship in a way a billing engine does not. Its built-in retention toolkit, Paddle Retain, uses performance-based pricing with no published price. Decide the merchant-of-record question first; if the answer is yes, Paddle is hard to argue with.

5. Seal Subscriptions

Seal is a Shopify-native subscription app: billing lives inside the storefront, checkout, and customer accounts your subscribers already use. For commerce-led brands, that native fit beats importing a standalone billing engine. The capability trade-off is billing depth — native apps focus on selling and managing subscriptions rather than complex invoicing — which is the right trade for most storefront-led models.

6. Skio

Skio is another Shopify-native option, built around the subscriber experience: managing plans, skips, swaps, and renewals inside the shop. Like the other native apps, its strength is the storefront and subscriber portal, not finance-grade billing machinery. Judge it on how your subscribers will manage their subscriptions day to day.

7. Loop Subscriptions

Loop Subscriptions serves the same Shopify-native category, with a focus on subscription-box and replenishment patterns — recurring orders, bundling, and retention inside the store. If your model is boxes or consumables sold through a storefront, Loop's shape will feel familiar. As with Seal and Skio, confirm the billing edge cases you need before assuming a native app covers them.

8. Swipe Again — the recovery layer, not the engine

We are including ourselves to make a structural point, and we will state our role precisely: Swipe Again is not a billing engine. It is the failed-payment recovery layer that works across nine of the platforms above — Stripe, Recharge, Seal Subscriptions, Skio, Loop Subscriptions, Chargebee, Recurly, Braintree, and Paddle. You can see the full list on our integrations page. Whichever engine you choose, its native dunning is a baseline; a dedicated layer extends it with decline-aware retries, broader outreach, backfill, and cancel deflection, and the layer survives an engine migration if you switch later.

The layer costs $179/mo flat, or $1,799/yr — no percentage of recovered revenue, no MRR tiers. It includes decline-code-aware smart retries (up to 6 attempts over about 16 days; hard declines are never retried), branded dunning emails and card-update pages, SMS in the sequence, cancel deflection with Discount, Pause, and Service offers, and a 90-day backfill on connect. Setup is self-serve with a 14-day trial, a card upfront, and connect in about 2 minutes. The guarantee, verbatim: "Recover $179 in 30 days, guaranteed — or Swipe Again is free the next 30 days".

The dunning question every buyer should ask

Every engine on this list will tell you it handles failed payments. Ask three follow-ups. First: are retries decline-aware — does the system treat an insufficient-funds decline differently from an expired card, and does it refuse to retry hard declines? Second: what outreach surrounds the retry — branded emails, card-update pages, SMS — or a single generic notice? Third: what happens to the backlog you already have on day one? Native dunning generally answers these at a baseline level. That is not a criticism; billing engines are built to bill. Recovery is a separate discipline, and across 5.4M failed payments, insufficient funds is the largest decline category at 40.6% (Churnkey analysis of Stripe data) — a category where retry timing, not retry volume, decides the result.

How to choose

1. Start from your centre of gravity. Payments-led, storefront-led, or finance-led — each points at a different category above.
2. Model pricing at scale. Percentage-of-billing shapes are cheap early and expensive later; flat and tiered shapes invert that.
3. Total the real stack. Engine plus cancel flows plus recovery add-ons, not the headline plan.
4. Plan recovery separately. Decide your dunning layer as its own purchase, whichever engine wins.

The bottom line

There is no universally best billing engine — there is a best fit for your model. Stripe Billing for Stripe-centred teams, Chargebee or Recurly for dedicated billing depth, Paddle when merchant-of-record simplicity wins, and Seal, Skio, or Loop when the storefront is home. Pick the engine for billing. Then treat failed-payment recovery as the separate layer it is, priced flat and judged on recovered revenue.

Frequently asked questions

What is the difference between a billing engine and a recovery tool?

A billing engine creates subscriptions, stores payment methods, and charges on schedule. A recovery tool works the failures: decline-aware retries, dunning outreach, card updates, backfill, and cancel deflection. Most businesses need an engine, and many add a recovery layer on top.

How is subscription billing software usually priced?

Three shapes dominate: percentage of billing, monthly tiers, and flat fees. Chargebee, for example, charges 0.75% of billing above its plan thresholds. Model each shape at your expected volume in two years, not just today.

Do billing platforms include dunning?

Yes, every major platform includes native dunning as a baseline. The depth varies, and dedicated recovery tools exist because the baseline leaves room: decline-aware retry timing, SMS, branded card-update pages, backfill, and cancel deflection are usually layer features.

Should a Shopify subscription brand use a standalone billing engine?

Usually not. Native apps such as Seal Subscriptions, Skio, and Loop Subscriptions keep billing inside the storefront and customer accounts. A standalone engine makes sense when billing complexity outgrows what a native app handles.

Is Swipe Again a billing platform?

No. Swipe Again is a recovery layer that works across nine billing platforms, including Stripe, Chargebee, Recurly, Braintree, and Paddle. It costs $179/mo flat and handles retries, dunning, backfill, and cancel deflection.
