Trastienda, a boutique studio for Tiendanube apps.
Many stores still convert their dollar prices to pesos by hand. Pizarra, the studio’s first app, does it every day, at the exchange rate you choose. Brand, website, product and engineering, all done in-house.
In development Coming soon to the Tiendanube App Store.

Pizarra, por trastienda
Pizarra: your dollar prices, kept current in pesos.
You mark which products are priced in dollars, and Pizarra converts those prices into pesos every day, with the exchange rate, margin and rounding you choose. If the exchange rate spikes, Pizarra pauses and asks you to confirm.
Five exchange rates to choose from
- Official
- MEP
- Blue (informal)
- Wholesale
- Card rate
How Pizarra does the math
Example- Price in dollars
- US$899
- Margin, added to the dollar price
- + 10% = US$988.90
- MEP dollar rate
- × AR$1,536.50
- Exact result
- AR$1,381,313.50AR$1,519,444.85
- Rounded up to the nearest AR$100
- AR$1,381,400AR$1,519,500
What we did
We built it with the same rules we apply to every project: phone first and clear in five seconds. The numbers you see are examples and are labeled as such.
- Brand
- Trastienda and Pizarra from scratch: logo, icons, colors, typography and voice.
- Website
- Not yet published: a calculator to convert a price or a price list at the day’s rate, plus an interactive preview.
- App
- It’s built to run inside the Tiendanube admin, on its design system, on desktop and mobile. For now it runs on simulated stores.
- Video
- The product animated in code: a looping video for the website.
- Engineering
- Calculations exact to the cent, encrypted credentials, signature-verified Tiendanube notifications and WCAG 2.2 AA accessibility as the target.
A family ready for more apps.
Each app has its own name, color and icon, and all of them are signed “por trastienda” (Spanish for “by trastienda”).
