Where an operation outgrows its tools
These arrive together because they're one problem: the operation outgrew its tools. Replatforming without fixing the systems behind it moves the fault rather than clearing it.
Stock
Two channels disagree about what's on the shelf. Someone reconciles it by hand every morning, and oversells anyway.
Fulfilment
Picking is the bottleneck, a second warehouse made it worse, and it's unclear whether a 3PL would be cheaper than fixing it.
Systems
The ERP was chosen for a smaller business. Every new channel adds an integration without an owner.
The ledger
Marketplace payouts arrive netted, landed cost is a guess, and the month takes four days to close because three systems have to be argued into agreement.
The platform
Plus where it pays, and only there
Whether Plus is the right answer, what it costs against what you run now, and what the move involves. The ceiling you've hit is either a platform limit, which Plus lifts, or an operational one, which Plus would move rather than clear.
Stock and the warehouse
One stock truth, shown to every channel
Where the stock master lives, how availability reaches each channel, and whether a second warehouse or a 3PL is the cheaper fix. Stock is four numbers, and a channel should only ever be shown one of them.
On hand
Physically on the shelf, in every location.
Committed
Promised to an order, so no longer yours to sell.
Available
On hand minus committed. The only number a channel should see.
Incoming
On order from a supplier, with a date.
Multichannel
Every channel selling from one pool
Marketplaces, B2B and retail pulling on one inventory pool, each with its own fee mechanics, its own returns behaviour and its own idea of what an order looks like.

Compare the packagesOne operation accountable
Crossdock delivers as prime contractor. The platform work, the integrations and the cutover sit under one contract, with named specialist partners for the slices that warrant them, named to you before anything is signed.
The migration is rehearsed before it's run. Data is reconciled repeatedly so the delta shrinks, the rollback plan exists before the DNS changes, and the conditions that abort the cutover are written down in advance rather than argued about at two in the morning.
