Why Mixing Without Structure Drains Profit & Scrambles Taxes
Blended books hide true profitability per business, misallocate expenses, complicate tax prep (Schedule C vs multi-entity), and make growth decisions guesswork. Class tracking keeps one file while giving clear separation.
How to Use QuickBooks Online Class Tracking
Enable class tracking in settings. Create classes for each brand, location, or revenue stream. Assign classes to every transaction (income, expenses, bank transfers). Run P&L by class for true per-business performance.
Complete Setup Plan & Allocation Rules
1. Enable classes & locations if needed.
2. Map classes: BrandA, BrandB, Shared.
3. Set allocation rules for shared expenses (rent, software).
4. Clean historical data (reclassify).
5. Set default classes on recurring transactions.
Reporting Toolkit & Decision Triggers
P&L by class, balance sheet by class, profit per class. Triggers: when one class consistently loses money, when shared expenses exceed 30% of revenue, when audit risk rises from mixed books.

Frequently Asked Questions
1) Can I track multiple businesses in one QuickBooks file?
Yes — use class tracking (or locations) to separate revenue/expenses while keeping one company file.
2) When should I use separate files instead?
Different entities (LLC vs S Corp), very different accounting needs, or when class tracking becomes too complex.
3) How do I allocate shared expenses?
Document allocation method (revenue %, headcount, square footage). Apply consistently. Keep memo.
4) Does class tracking work for tax prep?
Yes — run P&L by class for Schedule C breakdowns or entity-level reporting. Helps defend allocations.
5) What if I add a third business later?
Add another class. If complexity grows, consider separate files or entities — we can guide the split.
