I built a spreadsheet monster managing my Airbnbs. Here's why I burned it down.

When I started letting my first flat on Airbnb, I was broke, and convinced I could manage it on my phone. One property, one cleaner, one Google Calendar. It worked. For a while.

By the time I had four properties, I was running a Google Sheet that had grown sixteen tabs deep. One tab per property. One tab for cleaning rotas. One for check-in instructions. One for Wi-Fi codes. One for past damage claims. You get the picture.

Then one Sunday in February, two things happened. A guest checked out at 11am from Property A. A guest checked in at 3pm at Property A. Tight, but doable. Except my cleaner had been sent to Property B on the rota that week — because I'd updated one tab and not the other.

The new guest walked into a flat that hadn't been touched. There were used towels in the bathroom. The bins were full. There was a half-eaten pizza on the kitchen counter.

I lost the booking. I refunded in full. The guest left a one-star review that took me three months to bury under newer ones. I lost roughly £1,400 in revenue that single weekend, plus the long tail of damage to the listing's ranking.

The real problem wasn't the spreadsheet

It was that the spreadsheet had no concept of "what happens next." It was a static record. It couldn't tell my cleaner what to do. It couldn't confirm she'd done it. It couldn't show me a photo of the made bed.

I tried a few off-the-shelf tools after that. They were either built for big property management companies (overkill, £300/month, a thousand features I'd never use) or they were glorified to-do list apps with no concept of what an STR turnaround actually involves.

So I started building my own. Just for me. Just to solve the specific pain.

What I needed (and what most operators need)

Looking back, the requirements were simple, but no tool I tried did all of them well:

1. Tasks tied to properties. Every cleaning, every maintenance issue, every supplier delivery — visible per property, not buried in a calendar.
2. Checklists that the cleaner actually has to complete. With photos. With proof. Not "she said it was done."
3. The ability to block completion until critical items are done. Bins emptied. Bed made. Bathroom clean. No green tick until I have visual evidence.
4. A system that worked offline. My cleaners often work in basements with one bar of signal.
5. Reports I could send to my owners without having to spend an hour every Monday assembling them.

That last one was the killer. I had three owner-investors who wanted weekly reports. I was spending five hours every Sunday night writing them. That five hours was my entire weekend, gone.

What changed

I started building a proper tool. Tasks tied to properties. Checklists with photo proof. Auto-generated reports with the cleaner's photos and timestamps already in them. Branded for the owner — their company name, their email — not mine.

I sent the first auto-generated report to one of my owners. He replied within 10 minutes:

"This is the most professional thing I've seen from anyone managing my property. You're not getting fired any time soon."

That was the moment I realised this wasn't just my problem. It was every small operator's problem.

The lesson, if there is one

The spreadsheet didn't fail because spreadsheets are bad. It failed because what I needed wasn't a record-keeper — it was a system. Something that didn't just track work, but actually drove it. Told the right person what to do, made them prove they'd done it, and gave me peace of mind that I could send a guest to a property I hadn't physically visited in three weeks.

If you're running 2 to 20 properties and you're still managing it through WhatsApp groups, Google Sheets, or your head — I see you. I was you. There is a better way, and it doesn't require a £1,000/month enterprise tool.

That's the entire reason Sorted BNB exists.
