Orders that invoice themselves back.

Send a purchase order to a supplier. When their invoice arrives, Guliel matches it to the original order, flags any line-item or price drift, and queues the reconciliation. If the supplier is also on Guliel, the round-trip is closed inside the platform.

• Bidirectional supplier flow — unique to Guliel.
• Match invoice ↔ PO line items automatically; surface drift before payment.
• Same supplier table across all your organizations.
