Key takeaways
Recurring billing formulas
Monthly recurring revenue = active subscribers × average monthly charge
Revenue at risk = failed payments × average charge
Recovered revenue = failed payments × recovery rate × average charge
Involuntary churn (%) = unrecovered failed payments ÷ active subscribers × 100
Worked example (illustrative numbers)
A membership business bills 400 customers $50 a month. All numbers are illustrative.
- Monthly recurring revenue = 400 × $50 = $20,000
- Failure rate 6%: 400 × 6% = 24 failed payments → revenue at risk = 24 × $50 = $1,200
- Retries, card updates and reminder emails recover 15 of 24 (62.5%) → recovered = $750
- Unrecovered = 9 × $50 = $450 per month, about $5,400 per year
- Involuntary churn = 9 ÷ 400 × 100 = 2.25% per month
- With no recovery process, the loss would be $1,200 per month, or $14,400 per year
Illustrative numbers only. Your costs depend on your provider, card mix and how you accept payments.
Recurring billing and card on file
Recurring billing charges a saved payment method automatically: monthly memberships, service contracts, subscriptions or installment plans. Card on file is broader: it means you store a token for a customer's card so you can charge it later, on a schedule or as needed, with their permission.
Card networks have rules for storing credentials and running recurring or unscheduled charges, including how you get consent and how you mark transactions. Consumer protection laws, including federal rules for online subscriptions and some state automatic-renewal laws, also apply to many recurring programs. Requirements change and vary by state, so check current rules and talk to your advisor.
Invoice payments and payment links
Invoice payments let a customer pay a bill by card or ACH through a secure link in the invoice. A standalone payment link does the same for a set amount without a formal invoice, sent by email or text. Both reduce the time between billing and getting paid, and both avoid taking card numbers over the phone or by email.
Offering ACH alongside card on invoices can lower cost for larger amounts, since ACH fees are often flat or capped. Our ACH payments guide covers timing and returns.
Why payments fail
Common reasons a scheduled charge declines:
- Expired or replaced card
- Insufficient funds or credit limit
- Issuer fraud filters flagging an unexpected charge
- Closed account or lost or stolen card
- For ACH, insufficient funds or an invalid account, which returns days later
Failed payment handling that works
A good recovery process combines automation with clear communication:
- Automatic card updates, where available, refresh expired or reissued cards
- Smart retries spread over several days rather than repeated immediately
- Friendly emails or texts with a secure link to update payment details
- A clear grace period before service is paused
- Reporting on failure reasons so you can fix patterns
What to look for
- Tokenized storage and PCI compliance support
- Flexible schedules, proration and pause options
- Automatic card updates and configurable retry rules
- Card and ACH options on invoices and payment links
- Customer self-service to update payment details or cancel
- Clear reporting on recurring revenue, failures and recoveries
Designing a recurring program customers trust
Clear terms reduce both failed payments and disputes. At signup, show the price, billing frequency, renewal date, and how to cancel, and send a confirmation that repeats them. Before an annual renewal or a price change, send a reminder with enough notice for the customer to decide.
Billing descriptors matter here too. A customer who sees an unfamiliar name on a monthly statement may dispute it rather than cancel. Use a descriptor that matches your brand and includes contact details.
Track recurring metrics monthly: active customers, monthly recurring revenue, failed payments, recovery rate, cancellations and chargebacks. Together they show whether losses come from voluntary churn, which is a product question, or involuntary churn, which is a payments question.
Card vs ACH for recurring charges
Card is familiar and approves instantly, but percentage fees add up on larger charges and cards expire. ACH usually costs less and bank accounts change less often, but payments take longer to settle and can be returned days later. Many businesses offer both and let the customer choose, sometimes encouraging ACH for larger plans.

Common mistakes
- Charging a saved card without clear, recorded consent
- Making cancellation hard, which drives chargebacks and can violate rules
- Retrying a failed charge many times in one day
- Not reminding customers before an annual renewal
- Storing card numbers in spreadsheets or email

Common questions
What is recurring billing?
Automatic charges to a saved card or bank account on a set schedule, with the customer's authorization.
Is it legal to keep a customer's card on file?
Yes, with clear consent and secure, tokenized storage. Card-network rules and consumer laws set specific requirements, so check current rules and talk to your advisor.
How do I reduce failed recurring payments?
Use automatic card updates, spread retries over several days, and send customers a secure link to update their details.
What is a payment link?
A URL that opens a secure payment page for a set amount, sent by email or text. It's useful for invoices, deposits and one-off charges.
Should I offer ACH for recurring billing?
For larger or business-to-business charges, ACH often costs less than card. Plan for slower settlement and possible returns.
