The cost difference. A multi-LLC RE investor with 5 LLCs needs 5 separate QuickBooks Plus subscriptions. That's $90/mo × 5 = $450/mo. MyAIAccountant Investor at $79/mo covers the same 5 LLCs.

The category difference. QBO has no Form 8825 fillable PDF, no K-1 worksheets, no real-estate-tuned AI categorization, no mortgage P&I auto-split, no MTR classification, no tenant security-deposit tracking, no per-state occupancy tax tracking. The work to bridge those gaps is what your CPA charges you $1,500-$3,500/yr for.

The consolidation gap. QBO supports multi-entity through separate subscriptions, but does not provide GL-layer consolidation with intercompany eliminations. You either roll up manually in Excel or use QBO Advanced + a consolidation app like Konsolidator ($300+/mo more).

Where QBO wins. Inventory, payroll, sales tax for non-real-estate businesses, and a deeper third-party integration ecosystem. If you have a dental practice and 3 rentals, you might run QBO for the practice and MyAIAccountant for the rentals.
