Checkout & Payments Rescue
Your checkout is dropping paid-for orders. I find the cause in 48 hours and fix it — flat price.
Stripe declines, failed-payment leakage, broken subscriptions, 3DS/SCA errors, refunds that don't go through, webhooks that never mark the order paid — diagnosed and fixed by a senior engineer who runs payments on a real store every day. Flat price, proven live.
- 2,000+ orders/mo on my own store
- 150K visits/mo · 9+ ROAS
- 6+ yrs production
- 125k+ LOC WooCommerce/PHP
Every failed payment is a customer you already paid to acquire — gone at the last step
You spent on ads and earned the click. Then the payment failed silently, the subscription didn't renew, or the order never got marked paid — and the money vanished at the exact moment it was supposed to land. It's the most expensive bug in your funnel, and it compounds every day it's live.
- Stripe declines and failed payments you can't explain
- Failed-payment and dunning leakage — renewals that quietly don't recover
- D Secure / SCA challenges that loop or block legitimate cards
- Webhooks that don't fire — the payment succeeds but the order stays unpaid
- Refunds, partial refunds and disputes that break or don't reconcile
- Checkout drop-off where customers bail at the payment step
Payments are where 'looks done' quietly loses money
Payment flows pass a test transaction and then fail on real cards, real banks and real SCA enforcement. Generic devs and AI tools get the edge cases wrong — and you only find out when revenue dips. Closing exactly that gap is what I do.
- Sandbox-green is not production-safe — failures surface against real banks
- Webhooks, idempotency and reconciliation are where money silently leaks
- A 'WooCommerce expert' is not always a payments expert — that difference is your revenue
How it works: 48-hour diagnosis, then a flat-price fix
- 1 Book the 48-hour diagnosis. I reproduce your failing payment and find the root cause.
- 2 You get a written diagnosis plus a flat fix quote ($1,200–$4,500).
- 3 The $450 diagnosis is credited to your fix (and refunded if I can't pinpoint the cause).
- 4 I fix it and prove it with a real successful transaction end-to-end.
What's included — and what's not
Flat pricing — no hourly surprises
Everyone starts with the 48-hour diagnosis, credited to your fix (and refunded if I can't find the cause). You approve a flat fix price before I touch anything.
Single-issue checkout fix
One gateway or failure fixed and proven live — Stripe declines, an SCA loop, or webhooks that never mark orders paid.
$1,200 flat
Multi-issue / tangled checkout
Several failures across gateways, subscriptions or refunds — fixed, reconciled and proven with real transactions.
$2,500 flat
Complex / subscriptions / headless rescue
Deep billing, headless or full reconciliation rescue across the payment stack.
$4,500 flat
48-hour diagnosis — first step, credited
Root-cause investigation plus a written diagnosis and a flat fix quote. Refunded if I can't pinpoint the cause.
$450 (credited to your fix)
Care plan (optional, ongoing)
Monitoring and priority fixes so checkout doesn't silently break again.
$190 / $390 / $690 per month
You take no risk on the diagnosis: it's refunded in full if I can't pinpoint the cause within 48 hours, and credited to your fix if I do. You approve a single flat fix price before any work — never an hourly meter. The only thing that isn't refundable is the revenue you keep losing while checkout stays broken.
I run payments on a real store every day — this isn't theory
I'm Marc Stan — I run the payment path on a WooCommerce store doing 100–150K visits a month, so I feel every broken checkout as lost margin, same as you. 6+ years production full-stack, 125k+ lines of WooCommerce/PHP. I prove every fix the only way that counts: a real, successful transaction on your own checkout before we're done.
- I run live payments on a 100–150K-visit/mo store I operate
- 6+ years production full-stack; 125k+ LOC WooCommerce/PHP
- Stripe, PayPal, wallets and ACH — plus Redsys/Bizum for the EU
- Every fix proven with a real successful payment on your store
Limited rescue slots — book before the bleed continues
- A few concurrent rescues so diagnosis stays inside 48 hours
- Same-day emergency triage via WhatsApp for active revenue bleeds
- Every hour checkout is broken is orders you don't get back
Questions store owners and agencies ask
Do you only do Stripe?
Stripe is the core, plus PayPal and wallets (Apple/Google Pay, Link) and ACH for US customers. I also handle Redsys/Bizum for European bank gateways, which most devs can't.
Is the diagnosis really refundable?
Yes. If I can't pinpoint the cause and give you a written plan within 48 hours of access, the diagnosis fee is refunded. If I do find it, it's credited to your fix.
Can you recover failed or declined subscription payments?
Yes — dunning, retries, smart recovery and the webhook/reconciliation plumbing behind it. That leak is often the biggest and quietest one.
Will you need access to our payment provider?
Read-level access to logs and a staging/test path is usually enough to diagnose; I'll tell you exactly what I need and never log real card data.
How fast?
Diagnosis in 48 hours; most fixes 1–3 weeks depending on scope.
