What is included inside the 13-Week Cash Runway Planner and 3-in-1 Small Business Finance Bundle ZIP downloads?

The standalone 13-Week Cash Runway & Burn Rate Planner (Etsy #01, $7.20 w/ VAULT20SALE) includes a 6-tab Microsoft Excel (.xlsx) and Google Sheets workbook covering Tab 1 (10-Minute Weekly Ritual), Tab 2 (Settings & Cash Buffer Thresholds), Tab 3 (13-Week Rolling Cash Flow Forecast with auto OK / WATCH / LOW CASH flags), Tab 4 (Recurring Subscription Audit), Tab 5 (AR & AP Clearing Log), and Tab 6 (3-Scenario Stress Test).

How does the 3-Scenario Stress Test protect agencies and solo founders from cash crunches?

Instead of relying on static monthly bank balances, the 13-Week Rolling Forecast models exact weekly cash inflows and outflows across 91 days and compares your ending weekly cash balance against your custom Low-Cash Buffer and Watch Thresholds. Toggling the -25% Client Revenue Dip scenario immediately highlights which exact week your post-tax cash balance crosses into WATCH or LOW CASH territory so you can pause non-essential subscriptions or accelerate overdue AR collections weeks in advance.

Do these workbooks require paid monthly accounting software subscriptions or macros?

No. Every workbook uses 100% native, transparent Excel and Google Sheets formulas with zero VBA macros, zero third-party plugins, and zero monthly SaaS subscription fees. You pay once ($5.60–$7.20 for a single workbook or $9.60 for all 3 workbooks w/ VAULT20SALE on Etsy, or $22.00 w/ LAUNCH2 on Gumroad for the 3-Kit Freelancer & Studio Operating System) and own the files forever.
