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

Why Kestrel
* Storage charges are approved automatically by default; a warehouse can turn that off.
Legacy WMS: typical on-premises systems, connected to other software through EDI, file transfers or custom integration. Limited: offered by some products, often as an add-on or with little flexibility. Individual products vary.
Solutions
Owners and general managers
Visibility across the operation without chasing staff for updates.

Pilot Consultation
A guided pilot starts with discovery and a written scope, and ends with a closeout review against success measures we agree with you. A named Lumabyte owner looks after it throughout.
We learn how your operation runs today: your clients, your workflows, and the systems you use now.
You receive a written scope of what the pilot covers, so we agree on it before any work starts.
One named person at Lumabyte owns your onboarding and is your point of contact throughout.
Together we agree how the pilot's success will be measured, in terms that matter to your operation.
At the end, we review the results with you against the measures we agreed.
We reply within 2 business days. Sending a request doesn't create an account or connect any of your systems.
