What Calius is

Calius is a desktop app for resellers.
You keep one inventory, list each item across several marketplaces, and let Calius handle the repetitive parts: relisting, offers, sales tracking, invoices, and shipping labels. Accounts stay local and sessions are encrypted.

​
What you can do

  • Manage one inventory across every platform.
  • List an item to multiple marketplaces and accounts at once.
  • Relist automatically to keep listings visible.
  • Answer Vinted offers with your own pricing rules.
  • Track every sale in one feed.
  • Create invoices and shipping labels from a sale.

​
How it works

Build your inventory

Add an item with photos, price, and details. (AI can write the title and description.)
2

List everywhere

Pick your platforms and accounts, then publish every listing at once.
3

Automate the rest

Listings refresh on their own, offers follow your rules, and sold items come down across platforms.
4

Track and scale

Monitor sales performance, profits, and history from one unified dashboard.
5

Track and invoice

Watch sales and revenue in the Overview, and create an invoice from any order.
