USPS

Refund Rules

USPS does not offer traditional SaaS refunds. However, they provide postage refunds for: voided labels (full refund within 1 year), undelivered Express Mail with money-back guarantee (full postage refund), and unused Priority Mail Express labels. No refunds for delivered packages or used services. Refund requests must be filed through official USPS channels.

Credit Policies

USPS offers limited credits through their adjustment/dispute process. Credits available for: billing errors (overcharges due to incorrect weight/dimensions), service failures (Express Mail guarantee violations), and processing errors (duplicate charges, void label charges). Credits are typically applied to future postage purchases or issued as refunds. Claims must be filed within specific timeframes (typically 30-90 days).

Contractual Terms

USPS operates under postal regulations rather than traditional SaaS contracts. Key terms: rates can change annually (typically January), no long-term commitments required, 30-day notice for major service changes. Commercial accounts have specific terms of service. No auto-renewal as it's pay-per-use. Price increases follow federal postal rate-setting procedures with public notice periods.

Integration Complexity

Technical Notes

USPS APIs use OAuth 2.0 for authentication. Rate limits vary by API (typically 1000+ requests/hour). Key considerations: separate sandbox vs production environments, webhooks available for adjustments/disputes, APIs have versioning (currently v3 for most). Some quirks: tracking data may have delays, address validation has specific formatting requirements, international vs domestic APIs are separate. Good documentation but complex pricing calculation logic required.
