We sell tools you actually own.
Completo is a store of premium Google Sheets templates, Excel spreadsheets, and spreadsheet-powered web apps. You pay once. You keep the file. No subscriptions, no per-seat pricing, no SaaS that disappears the day a startup runs out of runway. Buy a tool, own it forever, run it on infrastructure you already have.

Why we exist
The tools you use every day shouldn't be rented from a server.
Most software is sold as a subscription now. You pay monthly, forever, for tools that quietly hold your business hostage — your data, your workflows, your clients all live inside someone else's database. The day you stop paying, you lose access. The day the company shuts down, you lose everything. We've been there, and we've watched too many founders lose a year of bookkeeping to a dead startup.
Spreadsheets are the opposite. A Google Sheet or an Excel workbook is a file you can duplicate, share, version, and open ten years from now. It runs on free infrastructure you already have. It doesn't disappear when a billing email bounces. The modern “spreadsheet-powered web app” — a shareable link driven by a sheet you own — is the same idea, extended to the web.
Completo exists to make those tools findable, trustworthy, and worth buying. Every spreadsheet and web tool here is built in-house, tested with real data, and sold once — to you, forever. Google Sheets for the operators, Excel for the analysts, web tools for the makers. No subscriptions, no lock-in, no “contact sales.”
How we curate
Three rules, applied to every listing.
The store is small on purpose. Better a shelf of tools I'd actually use than 15,000 templates of unknown origin.
Tested with real data
Every template is opened, clicked through, and pressure-tested with real numbers before it goes live. If a sheet breaks the moment real data lands in it, it doesn't ship.
Built by one maker
Every tool in this store is designed, built, and maintained by the same person — no anonymous template factories, no outsourced formulas. What you buy is what I use.
Lifetime updates
When a template gets an improvement, you get the new version free — forever. The tool you bought last year is the same tool you keep using next year, only better.
Our promises
What you get with every purchase.
No subscriptions
Pay once. The file is yours. No monthly bill, no per-seat fee, no surprise price hike on renewal day.
We stand behind the files
Digital products are final sale, but if a download is broken or a file is missing, email us and we'll fix it — no interrogation.
Lifetime updates
Bug fixes, new features, compatibility patches — all free, forever, on every product you own.
Who's behind this
One maker. Every template signed.
Completo is built and run by one person — the same person who designs the templates, tests the formulas, answers the support tickets, and records the setup videos. There's no faceless team behind a logo: if you buy a template, the maker is the one who wrote every formula in it.
The templates start as tools built for real work — budgeting, sales tracking, inventory — and only make it to the store after they've survived real spreadsheets, real clients, and real deadlines. You can watch them being built and explained on the YouTube channel.
