If checkout breaks at 2 a.m., you’ll know before your customers do.

We run your money flows against your live site every few minutes. When one fails, you get an alert with a screenshot and a trace.

Case 008

Online shop · order emails

A phone on a stand with a monitoring alert: “Flow check”, “Order confirmation” and, in red, “spf=fail · dkim=none” and “Landed in spam”.

Google Workspace went live. Order emails stopped arriving.

A new SPF record left out the web host, so order confirmations land in spam or bounce.

Flow Watch questions. Before you book.

What’s the difference between Starter and Business?

Starter is €149 a month: 3 flows every 15 minutes, alerts by email. Business is €299 a month: 8 flows every 5 minutes, alerts by Slack and email, and a monthly report.

Do we own the scripts?

No. They run from our server and you pay monthly for the protection. If you stop, the checks stop.

Will the checks place real orders?

No. We use test accounts and payment test modes only, never real customer data.

What if we redesign the site?

Script updates for normal changes are included, capped per month. A redesign changes the flows themselves, so we quote it separately.

What does setup cost?

A one-off fee from €300 to €600, depending on how many flows and how complex they are. We confirm it after the call.
