About
Running a creative practice means wearing a lot of hats. This app handles the business ones.
The Gouache OS App Features
Interior Mockups
Drop your artwork into real interior settings so buyers can picture it in their home before they commit. Useful for DMs, your website, or just showing work in context.
Inventory
A simple place to log everything you've made, where it is, and what it's worth. No more spreadsheets.
Sales Tracking & Collection
Record sales, commissions, and consignments as they happen. See what's selling and what's sitting.
Payment Links
Someone wants to buy — send them a Stripe link and you're done. No back and forth, no invoices.
Collectors
Keep notes on the people who buy your work. What they own, what they like, how to reach them. The kind of thing that's easy to forget and hard to rebuild.
Whether you're just starting to sell or managing a waiting list, Gouache keeps the admin out of the way so you can get back to what you do best.
