FAQ
What do you need from me to diagnose the issue?
The error message or behavior you're seeing, access to the relevant code (repo or snippet), and a restricted Stripe API key or test-mode access. I'll send a short checklist when you message me — most diagnoses start within an hour.
What counts as "one issue"?
One error, bug, or broken flow and its direct cause — a failing webhook, a checkout that won't complete, a subscription charging wrong. I confirm exactly what's in scope in messages before you order, so there are never surprises.
My site is live and losing sales right now — can you help?
Message me immediately with the error. I respond in about an hour, and the same-day delivery extra prioritizes your fix. On live systems I work carefully test mode first, then a controlled deploy.
Can you fix webhook errors and missed events?
Yes — signature verification failures, missed or duplicate events, retry storms, and out-of-order processing are the most common issues I see. Fix & Fortify includes hardening so they don't come back.
Built with Lovable, Replit, or another developer — can you fix it?
Yes, this is a specialty. AI tools and rushed builds produce working demos with fragile billing underneath. I fix the immediate issue and flag what else is likely to break.
Will you explain what went wrong?
Always, every fix includes a plain-English explanation, and Fix & Fortify and Stripe Rescue add a written root-cause report your team can keep.
What if the problem is bigger than a fix?
I'll tell you straight, fix what's safely fixable, and quote the proper rebuild — with your fix order credited toward it. No patching things that need architecture.
Is my Stripe account and code safe with you?
Yes. I work with restricted API keys and test mode wherever possible, never need your login credentials, and I'm a certified Stripe developer and Stripe Partner. NDAs welcome.
Do you guarantee the fix?
If the issue we agreed on isn't fixed, I keep working at no extra charge until it is. Scope is confirmed in messages before you order, so we both know exactly what "fixed" means.
Do you fix Stripe Connect and marketplace payout issues?
Yes — stuck transfers, failed payouts, onboarding errors, and fee miscalculations. If the root cause is the platform's architecture, see #7: I'll fix what's fixable and map the real solution.
