We build the spreadsheet before you need it.
Completo is a small store of Google Sheets templates, Excel workbooks and spreadsheet-powered web tools. Each one is a finished piece of work — modelled against a real use case, run with real numbers, and documented inside the file — so what you download already does the job rather than being a grid you still have to build.

Why we exist
Most spreadsheet templates are an empty grid with a nice header.
You download one, open it, and find the modelling is still your job: the totals are typed in rather than calculated, the chart is a picture of somebody else's data, and the moment you add a month it falls apart. An afternoon later you have rebuilt it yourself, which is the thing you were trying to avoid.
The work worth paying for is the part nobody photographs — deciding what the sheet should measure, writing lookups that survive a blank row and a duplicate entry, wiring charts to ranges that grow, and writing down which cells a person is meant to touch. That is what a Completo file is: the modelling, already done.
The catalogue covers three platforms because the same job lands in different places. Google Sheets for operators who need to share and collaborate, Excel for analysts who want a workbook on their own machine, and browser tools for when a client should see a clean web page rather than your spreadsheet.
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.
A finished file
Formulas written, charts wired, sample data in place, and an instructions tab saying which cells are yours. Nothing locked, nothing hidden.
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.
