The problem

The work happens on the floor. The record of it lives in five other places.

Receipts on a clipboard, stock in a spreadsheet, labels in ShipStation, charges in someone's notes and client questions in a shared inbox. Every handoff is a chance to lose a unit, a charge or a client's trust.

  1. Today

    A pallet arrives short. The count goes on a clipboard, and the client finds out when their stock doesn't match.

    With Kestrel

    Receive line by line against the client's ASN. Damage and discrepancies are recorded at the dock and stay visible on the shipment.

  2. Today

    Storage and handling are billed from a spreadsheet at month end. Work nobody wrote down never reaches an invoice.

    With Kestrel

    Configured triggers create charges from each client's rate card, and staff review and approve them before they reach an invoice.

  3. Today

    Clients email to ask what's in stock and where their order is, and someone stops work to look it up.

    With Kestrel

    Each client signs in to their own portal to check stock, follow shipment tracking and review invoices.

  4. Today

    To find out what's waiting to be received, what still needs a label or which invoices are past due, you have to ask around.

    With Kestrel

    One dashboard lists inbound waiting to be received, outbound without a label and past-due invoices.

Operating Loop

Seven operations. One connected system.

Kestrel connects receiving, inventory, outbound, shipping, billing, reporting and the client portal in one platform, from dock receipt through client invoicing.

Receive with clear unit, handling-unit, lot, attachment, and discrepancy context.

Record receipts line by line against the client's ASN. Lot and expiry are required for lot-tracked SKUs, damaged quantities are recorded separately, and discrepancies stay visible on the shipment.

Pallets and cartons are tallied, attachments stay with the shipment, and a receiving wave recorded in error can be reverted.

Integrations

Connects to your existing stack.

Rate-shop and create shipping output through ShipStation, add rate responses from direct carrier accounts, and hand off invoices to QuickBooks Online. A partner API and signed webhooks connect your own systems.
