Real GTBuy Spreadsheet Examples: Before and After Workflows

Theory is useful. Real workflows are better. Here are three anonymized case studies from buyers who shared their before-and-after spreadsheet transformations.

Case Study 1: Sneaker Reseller, 30 Items/Month

Before: Tracked purchases in iPhone Notes. Lost two orders because the vendor changed their URL and the old bookmark broke. Spent 20 minutes every night scrolling through screenshots to find the lowest price. After: Built a gtbuy spreadsheet with vendor URLs, auto profit calculation, and status dropdowns. Found the lost-vendor problem in two minutes using the URL filter. Cut nightly admin to 4 minutes. Discovered that 30% of inventory was below $10 margin and pivoted to higher-tier releases.

Case Study 2: Vintage Clothing Collector, 15 Items/Month

Before: Excel file on a laptop, never backed up. Hard drive crashed. Lost six months of purchase history including condition notes for 80+ items. After: Moved to Google Sheets with daily auto-save and version history. Added a Condition column with dropdowns and a Photo URL column linking to Google Drive folders. Now shares the sheet with a buying partner who adds items while the collector is at work.

Case Study 3: Bulk Electronics Buyer, 200 Items/Month

Before: Used a basic inventory app that did not support vendor comparison. Paid $29/month for features they never used. After: Built a custom gtbuy spreadsheet with a Vendor Score sheet, bulk import via CSV, and a Dashboard with monthly profit charts. Cancelled the app subscription. The spreadsheet handles 5x the volume with better visibility. Total setup time: 3 hours. Monthly savings: $29 app fee + 8 hours of manual reporting.
