When the System It Connects To Changes Without Telling Anyone
The Automation That Never Complained
A business we work with had a simple, unglamorous automation. Every night, it pulled order data from a supplier's system and used it to update their inventory sheet. No drama, no maintenance, no one thinking about it. For months, it just worked.
Then the supplier made a change on their end — a renamed column, a slightly different format. Nothing they announced. Nothing they thought twice about. Why would they? It was their own system.
But on the other end, the automation didn't know how to read the new format. And here's the part that catches most owners off guard: it didn't stop. It didn't throw an error. It didn't send a warning email.
It just kept running — pulling numbers from the wrong fields, updating the inventory sheet with figures that looked plausible but weren't.
Nobody Noticed Until the Numbers Stopped Matching
Three weeks passed before someone noticed the inventory counts didn't line up with what was actually on the shelf. By then, orders had already gone out based on the bad data. Someone had to go back through weeks of records to figure out where things had gone sideways.
This is the risk that doesn't get talked about enough. Owners assume that once an automation is built and working, it stays working. But an automation only knows how to talk to the systems it was built to talk to — in the exact shape they were in on day one. When one of those systems changes shape, even slightly, the automation doesn't know it's wrong. It just keeps going, confidently, in the wrong direction.
The Fix Was Easy. Catching It Sooner Was the Real Problem.
Remapping the new format took about a day. We rebuilt the connection, and added something that should have been there from the start: a check that compares the incoming totals against what's expected before anything updates live. If the numbers look off, it flags it — instead of quietly writing bad data into the sheet.
That's the piece most automation setups are missing. Not smarter code. A second layer whose only job is to notice when something's drifted.
Why We Stay After We Build
This is the exact reason we don't hand off an automation and disappear. Every automation we build gets a daily check — not just "did it run," but "do the numbers coming out of it actually make sense." If a connected system changes its format or its rules, we want to know before you do, not three weeks after.
You get one simple dashboard showing what ran, what changed, and what needs a second look. No guessing, no digging through spreadsheets after the fact.
Most automation shops build it and leave. We stay — because a working automation today doesn't mean a working automation in three months, unless someone's actually watching.
If you have an automation running quietly in the background — pulling data, updating records, moving numbers between systems — it's worth asking when someone last actually checked its output.
