Why procurement breaks at agent speed
Procurement is the single most fragmented enterprise workflow: buyer, requester, finance, supplier, supplier-of-supplier, freight, customs, and AP — each on different systems, each with their own approval rules. When an agent starts handling sourcing decisions, the audit trail typically shatters: emails to suppliers, quotes in PDF attachments, POs in the ERP, invoices in a separate AP system, payment in treasury. Nothing connects.
A2A Procurement runs the whole chain on signed envelopes. The buyer agent signs the RFQ. Each supplier agent signs its quote with a price-validity window. The finance agent signs the PO. The ERP records the agreed-terms hash. When the invoice lands, the hash must match — or the AP agent flags it before payment.
PO-to-pay, on one rail
1. Signed RFQ
Buyer agent broadcasts a structured RFQ envelope. Supplier agents respond with signed quotes + validity windows. No more "the quote expired" disputes.
2. Signed PO
Finance agent signs the PO bound to the accepted quote hash. PO terms cannot drift in transit. The ERP records the hash as the source of truth.
3. Three-way match, automated
When the invoice lands, the AP agent verifies invoice hash against PO + receipt-of-goods envelopes. Match → release payment. Mismatch → exception queue.
Extends ProcureLock. If you're already running ProcureLock for PO-to-pay attestation, A2A Procurement is the agent-facing wire format on top of it. The same receipts; new clients.

Frequently asked
Do we need to replace our ERP or AP system?
No. A2A Procurement sits on top of your existing ERP and AP. We ship adapters for SAP, Oracle, Coupa, NetSuite, and Workday on the Enterprise tier. The signed envelopes are written back to the source-of-record system as structured fields — your ERP stays the system of record, A2A Procurement adds the signed audit chain.
How does this differ from ProcureLock?
ProcureLock is the human-driven and integrator-driven PO-to-pay attestation rail. A2A Procurement is the agent-facing wire format that runs on the same underlying receipts. Same crypto, same audit; different client. Many customers run both — humans use ProcureLock, agents use A2A Procurement, all receipts land in the same vault.
What happens to supplier agents that aren't on Hive?
The supplier side has two integration modes. Native: supplier runs an A2A Procurement agent and signs quotes directly. Compatibility: supplier responds via the legacy email/PDF flow and the buyer-side bridge agent constructs a signed envelope on receipt. Compatibility mode lets you onboard the long tail of suppliers without forcing them to integrate.
Is this admissible for Sarbanes-Oxley audit?
The receipts conform to ALCOA+ data-integrity standards (FDA-grade), with eIDAS 2.0 advanced electronic signatures. Major Big-4 auditors accept ALCOA+ chains as primary evidence for SOX 404 segregation-of-duties testing. We can provide an auditor briefing pack on the Enterprise tier.
How does pricing work for thousands of POs?
Per-PO at $5 stays flat at any volume on the Hire tier. The Rent and Lease tiers are unlimited-volume — the break-even versus Hire is ~200 POs/month for Rent and ~2,000 POs/month for Lease. Most mid-market customers land on Rent; most enterprise customers land on Lease.
Can this handle direct-material spend (not just indirect)?
Yes. The envelope schema supports BOMs, lot/batch identifiers, supplier-of-supplier chain (so you can trace component origin on a signed receipt), and freight + customs handoffs. Direct-material customers typically also use the StormLock parametric-trigger rail for supply disruption clauses.
