Marinette makes small, careful tools for the parts of life that run on group chats and spreadsheets: small businesses, schools, clubs, and carpools. The add-ons and templates run inside your own Google account.
For Google Sheets™
Turn spreadsheet rows into Google Calendar™ events. Edit the row and the event updates, and you preview every sync before anything sends.
For Gmail™
Saves any receipt from your email to Google Drive™ in one click, auto-named by date and vendor and filed by year. It can't see your inbox.
For Google Sheets™
Log expenses and mileage in a spreadsheet that knows what's deductible. Pick a category and the tax math happens on its own.
For Google Sheets™
Create, brand, and send invoices from a spreadsheet. One click turns a row into a professional PDF, ready to email.
For Google Forms™
Turn a form into a sign-up sheet with real inventory: full slots close themselves, and every booking lands on your Google Calendar™ with the guest invited.
For Google Sheets™
Asks every client for a review once the job is done, on a schedule you set. Private feedback comes to you first, and the public ask is never gated on it.
All six Marinette add-ons are live on the Google Workspace Marketplace™, free to install.
