Sell or dispose
Eventually an asset leaves the books. There are two ways out, and Carbon treats them as genuinely different actions, handled by different teams, with different effects. You sell an asset to a buyer, or you of it when it's done. Both start from an asset that's "Active" or "Fully Depreciated".
The number that anchors both is , what the asset is still worth on the books: its acquisition cost minus the accumulated against it.
Sell it
Selling a piece of equipment is a sales act, so it lives with the sales team. The Sell action drafts a real with a single "Fixed Asset" line pointed at the asset, priced at its net book value. From there it's the ordinary quote-to-cash flow (ship it, invoice it, collect), with the order line carrying a link back to the asset it came from.
Selling an asset hands it to quote-to-cash at book value.
The Sell action doesn't invent a separate sale mechanism. It creates a normal sales order, lined up at net book value, that ships and invoices like any other. The fixed-asset line just remembers which asset was sold.
Dispose it
When an asset is retired rather than sold, you dispose of it, an accounting action. Carbon posts the disposal as a write-off: it clears the accumulated depreciation, removes the asset at its full acquisition cost, and books the remaining net book value as a loss. The asset moves to "Disposed".
Disposing scraps the asset and books its remaining value as a loss.
The disposal entry reverses the asset off the books (debit accumulated depreciation, debit the write-off account for whatever book value remains, credit the asset account for its cost) and records that remaining value as a loss. It's a retirement, not a sale: no proceeds are collected on this path.
They're separate exits, not two names for one thing.
Selling drafts a sales order and leaves the accounting to the invoice; disposing posts the write-off directly and marks the asset "Disposed". One is a sales action at book value, the other an accounting action that retires the asset — choose by whether money is coming in or the asset is simply going away.
That's the asset lifecycle end to end: capitalized onto the books through a register or a purchase receipt, written down month by month through depreciation runs, and finally either sold at book value through quote-to-cash or disposed of as a write-off, the financial half-life of every machine on the floor.
