Elevate your shopping cart experience

Buku replaces a fragmented parcel operation of many carrier contracts, manual reconciliation, and no margin visibility with a single infrastructure layer. Operators keep the systems they already run; Buku sits underneath them.

Enterprise Rates

Access negotiated carrier pricing across a broad domestic and international network through one integration. Every shipment is rate-shopped automatically against the services you’ve enabled.

WMS and API integration

Plug Buku into your existing WMS for automated rate shopping, label generation at pack, and reconciliation. Or build against the REST API and run it as a programmable layer inside your own platform.

Buku Billing

A purpose-built billing engine for 3PLs. Configure markups, surcharges, and accessorial rules once; client invoices, AR, and reconciliation build themselves.

Tracking and analytics

Real-time shipment visibility from label to delivery, plus per-shipment profitability and invoice audit surfaced in dashboards built for 3PLs and brands.

International compliance

Duties, VAT, and IOSS handling with customs-validated labels, so international parcels clear without delays or surprise charges.
