Who does what
VAMOS moves the order; the decisions stay with the parties. This page draws the line: what the platform runs, what the seller owns, what the buyer owns. If a step is not listed as yours, the platform is doing it.
The line, stage by stage
| Stage | Seller owns | VAMOS runs | Buyer owns |
|---|---|---|---|
| Catalog | Product definitions, rates, avails, make-good policy | Versioning, integrity checks, distribution to every surface | Deciding what to buy |
| Order | Validation, the price lock, idempotency, the state machine | Submitting the order; the price to accept | |
| Approval | The decision: approve, reject, counter | Routing, SLA tracking, the audit record of who decided | Confirming counters and proposals |
| Placement (booking) | The traffic system of record | Writing the booked order into it, and confirming it landed | |
| Creative | Acceptance standards, air checks | Carrying creative_id references on order units | Producing and trafficking the spot to the seller |
| Delivery | Posting actuals in the declared currency | Attaching posts, reconciling guarantees, firing make-good policy | Verifying the post against the guarantee |
| Money | Invoicing the buyer (direct settlement) | State, fees, and optional cleared settlement | Paying the seller (direct settlement) |
What the platform doesn't do
- Form prices. Sellers publish rates; buyers accept or negotiate them. There is no auction and no platform algorithm in the price.
- Invent availability. Avails are ingested from sellers, tri-state, with sellout level. See Avails.
- Compute currencies. The platform records the source on every figure; it does not measure or license measurement. See Currencies.
- Take the approval decision. Gates where money commits are held by people (or by rules those people set). See Approve orders.
Creative trafficking today: the order carries a
creative_id reference into the buyer's own creative registry, and physical delivery of the spot runs on your existing path to the seller. Managed creative trafficking through VAMOS is on the roadmap; tell us if your desk needs it.
