What is CAM billing and why is it important?

CAM (Common Area Maintenance) billing is the process of allocating shared property expenses like insurance, maintenance, landscaping, and utilities to individual tenants or owners. It's crucial for mixed-use and commercial properties to ensure fair cost distribution and maximum expense recovery.

What are the problems with manual spreadsheet-based CAM billing?

Manual spreadsheet CAM billing is error-prone, time-consuming, lacks audit trails, doesn't provide real-time validation, requires recalculation for every change, and makes it difficult to track historical allocation decisions. This can lead to billing disputes, incorrect charges, and significant time waste for property managers.

What allocation methods does the CAM billing platform support?

Our platform supports five flexible allocation methods: Actual Usage (meter-based for utilities), Equal Split (divide evenly), Square Footage (proportional to unit size), Number of Bedrooms (for residential units), and Custom Percentage (saved templates for complex scenarios). Property managers can mix and match methods for different expense types.

How does the platform ensure billing accuracy and fairness?

The platform includes built-in validation checks that verify allocation percentages sum to 100%, ensure units have required data (square footage, bedrooms) before applying specific methods, track unit type changes with audit trails, provide automated reconciliation comparing property bills to tenant charges, and generate variance reports to identify discrepancies.

Automated reconciliation compares property bills to tenant charges

Automated Billback Reconciliation

Automatically reconcile every bill against tenant charges, with highlighted variances to maximize cost recovery.

Why Reconciliation Matters

Automated billing and reconciliation avoids:

Under-billing tenants, leaving money on the table
Over-billing tenants, creating disputes and legal issues
Spending hours manually comparing spreadsheet totals
Discovering allocation errors at year-end audits
Stuggling to explain variances to owners

Allocation Template Management

Create and save custom allocation templates for recurring billing scenarios.

Template Benefits

Reusable: Create once, use every month for the same expense type
Documented: Templates show why each tenant gets their allocation
Flexible: Different templates for different expense categories
Validated: System ensures percentages add up to 100%
Trackable: See when templates were created and last used

Example: Retail Plaza Insurance Template

Template Name: "Insurance - Square Footage Split"

Category: Insurance

Unit	Size	%
Retail 1	2,500 SF	35.7%
Retail 2	1,800 SF	25.7%
Office 1	1,500 SF	21.4%
Office 2	1,200 SF	17.2%
Total	7,000 SF	100.0%

Five Powerful Allocation Methods

Choose the right methodology for each expense type. Mix and match methods across different bill categories for maximum accuracy and fairness.

1. Actual Usage

Best For: Water, Gas, Electric with meters

Allocate based on actual metered consumption. The most fair and accurate method for utilities with submetering.

2. Equal Split

Best For: Trash, common area electric

Divide charges evenly among all selected units. Simple and straightforward for shared services.

3. Square Footage

Best For: Insurance, maintenance, CAM charges

Allocate proportionally to unit size. Industry-standard for commercial properties and CAM billing.

4. Number of Beds

Best For: Residential utilities without meters

Allocate based on bedroom count (Studio=1). Perfect for multifamily properties estimating usage.

5. Custom Percentage

Best For: Complex scenarios, negotiated splits

Create and save custom allocation templates. Perfect for anchor tenants or negotiated lease terms.

💡 Mix & Match

Ultimate Flexibility

Use different methods for different expenses on the same property.

Frequently Asked Questions

CAM (Common Area Maintenance) billing is the process of allocating shared property expenses to individual tenants or owners. This includes insurance, maintenance, landscaping, utilities, and other operating costs.

For commercial and mixed-use properties, accurate CAM billing is crucial for:

Fair cost distribution based on lease terms or property characteristics
Maximum expense recovery ensuring owners don't absorb costs that should be tenant-paid
Lease compliance honoring negotiated allocation percentages
Transparent communication showing tenants exactly how charges are calculated

Manual spreadsheet CAM billing creates significant challenges:

Error-Prone: Formula mistakes, copy-paste errors, and manual data entry lead to incorrect charges
Time-Consuming: Property managers spend hours each month on calculations and double-checking
No Audit Trail: Hard to track who made changes, when, and why
Limited Validation: No automatic checks that allocations sum to 100% or that data is complete
Version Control Issues: Multiple versions of "the spreadsheet" lead to confusion
Tenant Disputes: Lack of transparency makes it difficult to explain allocation methodology
Scalability Problems: Complex properties with multiple allocation methods become unmanageable

Our platform eliminates these issues with automated calculations, built-in validation, and complete audit trails.

Our platform supports five flexible allocation methods that can be mixed and matched for different expense types:

Actual Usage: Based on meter readings (perfect for water, gas, electric with submeters)
Equal Split: Divide evenly among selected units (great for trash, common area utilities)
Square Footage: Proportional to unit size (industry standard for insurance, maintenance, CAM charges)
Number of Bedrooms: Based on bedroom count with Studio=1 (ideal for multifamily utilities without meters)
Custom Percentage: Saved templates with specific percentages per unit (perfect for complex scenarios and negotiated lease terms)

Best Practice: Use actual usage for metered utilities, square footage for CAM expenses, and custom percentages for anchor tenants with negotiated allocations.

The platform includes multiple layers of validation and transparency:

Pre-Billing Validation:

Verifies allocation percentages sum to 100% (warns if not)
Ensures units have required data (square footage, bedrooms) before applying specific methods
Checks that total tenant charges equal the property bill amount
Validates date ranges don't overlap or have gaps

Audit Trails:

Tracks unit type changes with timestamps and user attribution
Records which allocation method was used for each historical bill
Saves allocation template modification history
Logs all user actions (who uploaded bills, when, what changes were made)

Transparency:

Tenant bills clearly show allocation methodology used
Calculation details available for tenant review
Automated reconciliation reports show variances
Historical data allows comparison across billing periods

Absolutely! This is one of the platform's most powerful features. You can select a different allocation method for each bill category.

Common Example for Mixed-Use Property:

Water: Actual usage (based on submeters)
Property Insurance: Square footage (proportional to unit size)
Trash Service: Equal split (same cost per unit)
Landscape Maintenance: Custom percentage (retail tenants pay more since they benefit from curb appeal)
Electric (no submeters): Square footage for commercial units, bedrooms for residential units

The platform remembers your allocation method choice for each bill type, making monthly billing fast and consistent. You can also create multiple allocation templates and choose between them for the same expense type if needed.

The platform provides comprehensive analytics far beyond what spreadsheets can offer:

Usage & Cost Analytics:

12-month trend analysis showing usage and charges over time
Unit-by-unit comparison charts to identify outliers
Filter by expense category (water, insurance, maintenance, etc.)
Filter by unit type (residential, commercial, retail)
Combine filters to analyze specific segments (e.g., "Commercial units' insurance costs")
