We're Eryn Tech, a studio that takes the messy, complicated parts of running your business and turns them into software that just works. From Shopify merchants to teams beyond, we build tools that are fast, focused, and made to last.
Metra keeps your trade catalog fixed at your trade discount off original retail, whether the sale comes from a scheduled promo, a manual edit, or an external feed like Matrixify or an ERP.
Explore Metra: B2B Sale Price LockLock trade and B2B prices so sale discounts never stack, wherever the sale is set.
Metra reacts to promotions from scheduled sales, manual edits, Matrixify, or your ERP. No exports and no workarounds.
Schedule promotions with an automatic start, end, and price revert. Every change logged with timestamps.
Founded in 2025, Eryn Tech started with a simple frustration — too much software is bloated, confusing, or just gets in the way. We're a small team that builds tools we'd actually want to use ourselves.
Our mission is to remove digital friction. We just think software should work well, feel good to use, and respect the people using it. That's the whole thing.
