💧 How to Split a Water Bill for Shared House in Australia (NSW, VIC, QLD, WA, SA)

😩 The Landlord’s Water Billing Headache

You’re not bad at math — splitting a water bill for a shared house in Australia is just messy:

💸 A tenant moved out, but the invoice arrived two months later — should you charge them?
📅 A tenant stayed only 10 days — do they owe a full quarter?
🚪 Some rooms were empty mid-bill — are you responsible?
📉 You agreed to a $30 cap per bill, but manually applying and verifying it is exhausting.
🔁 Multiple overlapping leases mean the bill never matches exactly.

If you manage rental properties in NSW, VIC, QLD, WA or SA, this isn’t rare — it’s quarterly reality.

💬 “It’s Not the Math — It’s the Chaos”

Landlords across Sydney, Melbourne, Brisbane, Perth, and Adelaide tell us:

“I just want to split fairly — but my spreadsheets are out of control.”

The more tenants and lease overlaps you manage, the more chaos emerges.
You deserve something better than Excel.
