Inventory: a price change proposed by Strato, previewed in the table before anyone approves it.

Built for the way stock actually moves.

Every number comes from a ledger, so what you see is what is on the shelf.

  • Ledger-true stock

    Every change is a movement with the balance after it. Nothing edits on-hand directly, so the count on screen is the count on the shelf.

  • BOMs within BOMs

    Assemblies pull sub-assemblies from stock or explode down to base parts, with expected waste built into the requirement.

  • Receiving and back-dating

    Book deliveries against suppliers with the date they really arrived. Lots keep their cost, so valuation stays honest.

  • Shelf life and FIFO lots

    Batches carry their expiry, the oldest leave first, and the shelf-life report shows what to move before it goes to waste.

  • Returns and write-offs

    RMAs, inspections and write-offs land in the same ledger as sales and builds, with the reason on each line.

  • Min, max and seasonality

    Reorder points, days of cover and monthly demand curves tell you what to order next and when.

  • Imports that explain themselves

    Map any export, create custom fields on the fly, and review exactly which fields change before a row lands.

  • Live for the whole team

    Owners, admins, members and viewers work on the same data in the browser, with presence and an activity log.

Strato

Ask for the change. Approve it once.

Strato reads your items, BOMs and movements, drafts the change, and shows it in the table before anything is written.

  • Plain language in, one proposal out

    A dozen price changes is one approval, not twelve. Per-item values, percentages and filters all fit in a single call.

  • Preview in the table

    Proposed rows turn orange in your inventory. Flip between current and proposed values, then apply from either side.

  • Reads run, writes wait

    Strato looks things up on its own. Anything that changes data waits for you, or for a teammate whose role allows it.

Runs on Gemini Flash with your own API key. Other agents can use the same tools over MCP.

Works with what you already run.

Shopify exports

Variant SKUs, quantities, prices, cost and images map on their own.

WooCommerce exports

Stock, sale and regular price, brands, weight and dimensions, plus the product id.

CSV and pasted sheets

Any spreadsheet works. Unknown columns become custom fields with one click.

MCP for other agents

Every Strato tool is available to any MCP client, gated by a token you set.

From spreadsheet to live workspace in an afternoon.

Pilots start with your own data, not a tutorial.

  1. Import the sheet you already have

    Paste or upload. Columns map themselves, custom fields are one click, and the review shows what changes before it lands.

  2. Invite the team

    Send each teammate an email invite. They sign in with a password or an emailed link, and everyone sees the same numbers live.

  3. Hand the bulk work to Strato

    Price updates, cycle counts, receiving, BOM edits. One request, one approval, and the ledger records who did what.
