Property Management Software vs Excel: Which Do You Actually Need?

Almost every agency in Kenya started on a spreadsheet, and a good number should stay on one. The question is not which tool is better in the abstract. It is whether you have crossed the line where a spreadsheet's weaknesses start costing you real money.

That line is not a number of units. It is the point at which more than one person needs the truth at the same time.

At a glance

3 to a spreadsheet, 6 to property management software. Counted from the rows below, and the count is not the decision.

Cost to start
A spreadsheet
Free. You already have it.
Property management software
A subscription, plus setup time.
Speed for a small portfolio
A spreadsheet
Hard to beat. Ten units, one person, one screen.
Property management software
Overhead you do not need yet at that size.
Two people working at once
A spreadsheet
One copy becomes three within a month. Nobody knows which is current.
Property management software
One record, with who changed what.
Proving a balance to a tenant
A spreadsheet
A cell. Whatever it says today, with no history of what it said before.
Property management software
A payment applied to specific charges, with the derivation.
Arrears ageing
A spreadsheet
Possible, and maintained by hand until the month somebody is busy.
Property management software
Falls out of the data automatically.
Landlord statements
A spreadsheet
Re-typed monthly. Errors are silent.
Property management software
Produced from the ledger.
Flexibility for an odd case
A spreadsheet
Total. Add a column and move on.
Property management software
Constrained by what the system models.
Surviving an audit or a dispute
A spreadsheet
Depends entirely on the discipline of whoever kept it.
Property management software
Corrections are entries, not edits. The trail stands.
What happens when the person who built it leaves
A spreadsheet
Nobody else understands the formulas.
Property management software
The process is in the system, not in someone's head.

Choose a spreadsheet if

You have a handful of units and manage them yourself.
You are the only person who touches the records, and you are disciplined about it.
Your tenants pay reliably and you have never had to reconstruct a balance.
Your portfolio is genuinely unusual and you need to model it your own way.
Cash is tight and the problem you have is not yet an administrative one.

Choose property management software if

More than one person needs to see or update the same records.
You are collecting on behalf of landlords, and owe them an account you can prove.
You have had a dispute where you could not quickly show what a payment settled.
Arrears are discovered late rather than while they are small.
You bill utilities from meter readings, where a wrong figure compounds quietly.
Month end takes days, and most of it is re-typing things you already recorded.

The honest answer

If you manage your own units and nobody else touches the records, stay on the spreadsheet. It is free, it is fast, and the honest answer is that software will not make you money at that scale. Anybody who tells you otherwise is selling.

What changes the answer is not growth in units but growth in people and obligations. The moment you are accounting to a landlord for money that is not yours, or two people are editing the same file, a spreadsheet stops being a record and becomes a claim. The cost of that is invisible until the month you have to prove something and cannot.

The practical test: could you show a tenant, right now, which specific charges their last payment cleared, and could a colleague do it without asking you? If the answer is no, the spreadsheet has already stopped working. You just have not been asked yet.
