TC's OS by TheCriners

Organize Everything. Sell Everywhere.

Inventory, sales, listings, and reports for resellers — built phone-first, so the shop in your pocket matches the stock on your shelves.

No account needed to look around this site. The app itself is invite-only during early access.

What TC’s OS does for your shop

Six everyday jobs, each kept honest: everything below works inside the app today, behind login, for you and the people you invite.

Cost it without the math

Every sale remembers its oldest cost first, so profit is worked out for you — no spreadsheets, no guessing which lot a sale came from.

Scope: works inside your business; only you and people you invite can see it.

Find it in seconds

Search every item by name, code, or bin, and see the available count at a glance — what’s on hand minus what’s already promised to a buyer.

Scope: works inside your business; only you and people you invite can see it.

Bring your spreadsheet

Upload your existing inventory, sales history, or marketplace listings and match the columns with a guided preview. Duplicates get flagged for review, and a big import can pause and resume.

Scope: works inside your business; only you and people you invite can see it.

List it everywhere, your way

Draft each listing once, then track where it stands on every marketplace. You always post and end listings yourself — the app prepares, reminds, and never touches your marketplace accounts.

Scope: manual-assisted only; the app never publishes or ends listings by itself.

A little AI help, where enabled

For enabled organizations, snap up to five photos and get listing suggestions you review field by field — nothing is filled in without your say-so.

Scope: enabled organizations only; suggestions stay inside your business until you accept them.

Know your numbers

Twelve reports — profit, cash, expenses, channels, products, trends, and more — with exports and printouts that match what you see on screen.
