Odyssey Apex is a financial operating system built specifically for roofing contractors on QuickBooks Online. Your books aren't lying on purpose, but insurance proceeds, retainage, supplements, mortgage holds, and recoverable depreciation break the way normal accounting reads your receivables. A single storm claim can involve four checks from four parties over four different timelines, and a generic AR tool just labels all of it "past due." Odyssey reads your QuickBooks through certified APIs and tells you what's actually collectible right now. It tags every invoice as insurance, retainage, or direct-pay, ages each on a roofing-aware clock, tracks live job profitability against your original estimate, and forecasts cash flow 90 days out, before the crunch hits. Three tools, one platform: Ledger (money owed), Insight (money made), and Forecast (money coming). Built for roofers doing $1M–$20M a year, residential, commercial, storm, or all three. Read-only by default, no migration, and it works alongside AccuLynx, JobNimbus, and your bookkeeper. Veteran-owned and founder-run.
