Purchase Order Partial Billing Sequence

Inputs: [purchase order lines], [two invoices], [received quantities], [currency]. Reconcile partial invoices against each purchase-order line. Track ordered, received, previously billed and newly billed quantities separately; identify overbilling without assuming delivery establishes approval. Show arithmetic and preserve unknown unit prices. Do not authorize payment. Produce a 15-second ledger animation adding the second invoice while leaving ordered quantities fixed. Adapt the presentation to [audience] and [tone]. End with a concrete check of the defining task detail against the inputs.

Confirm required reference images and timing inputs are present before generating. Keep objects, identities, spatial relationships and light direction consistent. Render the clip when video generation is supported; otherwise supply a timed shot list, reference checklist and generation-ready prompt, labeled as a production plan. Do not claim rendered output without an actual file. Check the opening, transition and final frame against the stated counts and geometry.
