There's nothing wrong with tracking your jobs on a spreadsheet. For a few jobs and one or two people it's free, everyone already knows how to use it, and it does the job. Plenty of good workshops run this way for years.
The problem is that nobody notices the week it stops working. There's no alarm. The cracks widen quietly until a job slips, a customer is let down, and you go looking for where it went wrong. These are the signs that tend to show up first.
1. The sheet is always a little out of date
You ask where a job is. You check the sheet. The answer is wrong, because the last update was two handovers and three hours ago. If the people doing the work can't realistically keep the sheet current while they're working, it has stopped being a record of what's happening and become a record of what someone last had time to type.
2. There are suddenly two versions
Someone is working off a copy they saved last week. The supervisor edits a row on the floor while the office edits the same row upstairs. One of those changes wins and the other vanishes, and you find out when the numbers don't add up. The minute more than one person needs to update job status, a single shared sheet starts losing data. Shared online sheets soften this. They don't fix it.
3. Splitting an order turns into a small project
A customer needs forty of a hundred now and the rest whenever you can manage. On a spreadsheet that's a new row, a note in a colour you hope someone notices, and a quiet prayer that nobody counts it twice when the invoices go out. Part-deliveries are exactly where money leaks. Work goes out the door, the row never gets marked, and it never gets billed.
This is the one that costs real money
Most workshops can live with a status update that's an hour late. What they can't afford is delivering work they forget to invoice. If you track part-deliveries by hand, assume a few have slipped through unbilled, and go and check. It's usually worth more than a month's subscription to anything.
4. Nobody can tell you how long anything took
A spreadsheet holds the current state and nothing else. So when a job like the last one comes in and you want to quote it, you're guessing at how long each step really took. No timestamps, no history, no way to look back. You price on memory and gut, and gut runs optimistic.
5. Keeping the tracker updated has become a job
When someone has to be chased to keep the sheet current, the tool has turned on you. It was meant to save time. Now it costs time and someone's patience. That's the clearest sign of the lot, and the easiest to miss, because by then you're used to it.
So what do you do about it
Not buy a bigger spreadsheet. The fix is to make the update happen on its own, as the work moves, so nobody has to remember. That's the whole idea behind scanning a QR code on each job: a worker scans to receive a job and scans to hand it on, the record updates itself, and the office sees the same picture as the floor. Part-deliveries split into their own finished jobs instead of becoming a note in a cell.
If you're not sure you've reached this point, the honest spreadsheet versus software comparison lays out where each one genuinely wins. But if you read two or three of those signs and winced, you already know. Start a trial and see how it feels to stop typing.
