Real Automation Behind the Spreadsheet, Not Just a Grid of Formulas
Welcome to BlackVortex Digital. We build Google Sheets tools for landlords, Airbnb hosts, and small business owners who are tired of doing their own bookkeeping math by hand.
Most spreadsheet templates you can buy online are just formulas: you still have to categorize every expense yourself, still have to remember to update the totals, still end up reconciling a year of receipts the week before taxes are due. We build something different. Every template in this shop runs real automation underneath the spreadsheet, using Google Apps Script, so it actually does the bookkeeping work instead of just formatting it for you. Type an expense and it categorizes itself. Log a trip and your mileage deduction calculates itself. Open the dashboard and your income, expenses, and profit are already totaled, by month, by year, by property.
Every product here is built to solve one real, specific problem for one real kind of buyer, not to be a generic all-purpose template. That means less setup, less second-guessing, and a tool that actually gets used instead of abandoned in a Drive folder after week one.
Each template is a one-time purchase; yours to copy, keep, and edit forever, no subscription. Setup instructions are plain-English, no coding knowledge required.
Thank you for supporting a small, independent shop. If you have questions before or after buying, reach out through Etsy messages; we're glad to help.
