Do I need to sign up to run the audit?

No. No account, no email, no sales call. Connect Stripe read-only (or paste a restricted key) and the report renders right on this page. The key method has an optional field for an emailed copy; leaving it blank changes nothing.

Is it safe to paste a Stripe key here?

You never paste a secret key. The form refuses sk_ keys outright and does not send them anywhere. A restricted key with only Invoices: Read can read invoice data and nothing else: it cannot move money, issue refunds, or change your account. The key is used for one read-only scan, never stored or logged, and you can revoke it from your Stripe dashboard the moment you're done.

What exactly does the audit read?

Your invoices from the last 90 days: amounts, statuses, and attempt counts. From those it totals what failed, what card retries recovered, and what's still open. With charge access it also samples decline reasons. It reads no card numbers (Stripe never exposes those to any integration) and makes no writes of any kind.

What's a restricted Stripe key?

A key you create at dashboard.stripe.com/apikeys with per-resource permissions. Unlike your secret key, a restricted key does only what you grant it. Stripe recommends restricted keys for exactly this situation: giving a tool the minimum access it needs.

Why might my report say the total is a floor?

Very large accounts can have more failed invoices than one scan walks within its time budget. When that happens the report says so and shows what it counted: a floor, not a total. The real number is at least what you see.

What happens after I see my report?

Whatever you want. The report is yours either way, with no obligation and nothing to cancel. If you want the still-open payments worked, Mendworthy sequences exactly that window: branded outreach plus a one-tap card-update link for each end-customer, on a flat fee with a 14-day free trial.

Free Failed-Payment Audit — See 90 Days of Stripe Failures, No Signup

FREE AUDIT · NO SIGNUP

A 90-day report of what failed payments really cost you — the total, what card retries recovered, and what's still recoverable — straight from your own Stripe data. No signup; it renders right here.

Run the audit

One read-only scan. Nothing stored.

No signup, no sales call. The report renders here and it's yours to keep.
Read-only, and it ends when the scan does. Connect Stripe and access is removed automatically after the scan — or use a restricted key and revoke it yourself.
Nothing is stored. Not the connection, not a key, not your invoice data.

Approve on Stripe's own page — nothing to create, nothing to paste. When the scan finishes, we disconnect ourselves automatically.

Run my free audit

About half a minute. Mendworthy appears under Settings → Authorized applications in Stripe just long enough to run the scan, then removes itself — so you can see the disconnect for yourself.

Just want a ballpark first? Try the failed-payment calculator. It takes ten seconds and asks for nothing but your MRR.

Two numbers, labeled separately

The report never blends history with opportunity. You see the damage and the actionable slice side by side.

The diagnosis

Lost to failed payments — last 90 days

Every invoice that failed in the window, including how much card retries recovered on their own and, when charge data is readable, why cards declined.

The opportunity

Still open and recoverable — last 14 days

The failed invoices recent enough to act on. This is the same window Mendworthy works from when you turn recovery on, so the number you see here is the number recovery would start with.

Common questions

What you're granting, exactly

A standard Stripe connection, approved on Stripe's own authorization page — the same kind of grant any Stripe app uses. We use it for exactly one read-only scan of your invoices, then immediately tell Stripe to disconnect us, whether or not the scan succeeded. If you check Settings → Authorized applications afterward, the connection is already gone, and we never store the access token. If you'd rather grant access that is read-only by construction, use the restricted-key method instead.
