There is nothing wrong with a spreadsheet for one property. You have one loan, one stream of rent, a handful of expenses, and a value you check once a year. A single tab handles it comfortably, and you always know roughly where things stand.
The problem is that spreadsheets scale linearly while a portfolio scales in complexity. Every new property doesn't just add a row — it adds another loan, another set of dates, another currency sometimes, and another set of formulas that have to stay in sync with everything else. That is where the cracks appear.
Where spreadsheets quietly break down
- Broken formulas — one deleted row or dragged cell silently changes a total, and you may not notice for months.
- No history — a spreadsheet shows today's numbers, but not how equity or value moved over time, which is exactly what portfolio decisions depend on.
- Manual valuations — updating what each property is worth is a chore that gets skipped, so the numbers slowly drift away from reality.
- Currency headaches — the moment you own a property in another country, a single-currency sheet either misleads you or turns into a maze of conversion columns.
- Version chaos — a file emailed to an accountant, copied to a laptop and edited on a phone quickly becomes several conflicting versions of the truth.
- It's fragile at tax time — the one moment you need the numbers to be right is the moment a hidden error costs you the most.
The real cost isn't the time — it's the blind spots
The obvious downside of a growing spreadsheet is the hours it eats. The bigger danger is what it hides. When updating the sheet becomes a burden, you update it less, and decisions start getting made on stale or incomplete numbers. You can't see which property is actually underperforming, or how much equity you really have to redeploy, because the tool was never built to answer those questions.
A spreadsheet is a record. A portfolio needs a system — something that keeps the history, updates the values, handles the currencies and answers the questions that actually drive your next move.

Akweno replaces the fragile spreadsheet with a purpose-built system for property investors. It keeps a full history of income, equity and value, consolidates multiple currencies automatically, and removes the manual formulas entirely — so the numbers stay accurate as your portfolio grows, not despite it.
