Fair Billing. Fair Usage. Real Savings.

What Sub-Billing Really Means

Water and sewer bills from the city often span long periods (monthly, bi-monthly, or more), making it hard to assign fair cost shares to tenants. Sub-billing solves this by using actual usage data from sub-meters and breaking down large bills into unit-level invoices.

How It Works (Our Method)

• Proportional Raw Usage: We use raw usage from unit sub-meters and compare them to total usage (or “ticks”) to determine each unit’s share — no matter the meter scale.
• Daily Rate Calculations: Big city bills are divided by the days in the billing period, creating a stable daily cost. That lets you invoice for any shorter period (month, partial month, etc.) without overcharging.
• Invoice Period Flexibility: Pick your invoice dates (as long as they fall within a property’s known bill periods) so even if meter reads are irregular, usage is traced correctly.
• Missing Data Warnings: If a unit doesn’t have meter reads covering the full period, you get a notification — so nothing slips through.

What It Saves You

• Less over-paying: When property bills cover long periods or include days when tenants weren’t there, owners often absorb costs. Proportional billing shares costs fairly.
• Better predictability: Customers see usage, start-end reads, and what they pay per day. That reduces surprise bills and disputes.
• Transparency = trust: With clear meter reads, usage vs billing periods, invoices link back to actual data.
• Conservation & accountability: Tenants pay for what they use, which encourages conservation and reduces property costs over time.
