From a single API module to a full white-label postal platform — Stipendia scales with your cross-border volume.
Four products, one platform — buy a single piece or the whole stack.
Payment & Compliance API
Full-stack API for HS classification, duty and tax calculation, landed cost, goods screening, payment collection, and customs data exchange. Each domain is sold independently or as a full platform.
Hosted Embeddable Widget
Drop-in DDP checkout for e-commerce merchants. Calculates duties at checkout, collects total landed cost via Stripe or Payment Gateway 2, and remits to customs. One-line embed for Shopify, WooCommerce, and WordPress.
Pre-paid DDP Mobile App
React Native app for US de minimis duty and tax prepayment. Users enter item details, get AI HS classification, see duty calculation, pay by card or cash at the postal counter, and receive a Declaration ID with QR code.
Postal Data Exchange
Integration layer with UPU ITMATT APIs for EDIFACT/EDI message exchange between postal operators, customs authorities, and IPC/UPU systems. Handles CARDIT messages, IMD reports, and CN23 customs declarations.
Six ways to deploy Stipendia — from a single API call to a fully hosted postal platform.
Carrier sends manifest → Stipendia classifies and calculates → Customer notified → Customer pays duties online or at counter → Goods released.
$1.95 + 8% of duty & tax, paid by the consignee
Merchant checkout calculates duties → Customer pays total landed cost upfront → Stipendia settles internationally via our clearing bank and remits to customs → No surprises at delivery.
From $1.95/order + 10% of duty & tax (buy-down to $0.50 + 4%)
Stipendia Prepay app → Enter items → AI classifies → Calculate duties → Pay by card → Get Declaration ID + QR → Present at counter → Goods shipped.
