Stamps.com is a web-based postage and shipping service designed primarily for small businesses, online sellers, and offices that regularly mail packages and letters through the United States Postal Service (USPS). The platform provides licensed PC Postage functionality so customers can purchase official USPS postage online and print postage directly to plain paper or adhesive labels. It combines rate shopping, batch label printing, shipment tracking, and reporting in a single application accessible via browser and a downloadable client.
Stamps.com is commonly used by sellers who need to streamline daily shipping—especially those operating on marketplaces such as eBay, Amazon, Etsy, and Shopify. It centralizes postage purchasing and label creation while preserving USPS discounts that would otherwise require a trip to a post office or a third-party account.
In addition to postage and labels, Stamps.com offers tools to manage returns, create customs forms for international shipments, validate addresses, store recipient and sender profiles, and produce detailed postage and shipping reports for bookkeeping and reconciliation. The service is integrated with several shipping and sales channels so shipments can be pushed from the selling platform into Stamps.com for fulfillment.
Stamps.com lets businesses buy and print USPS-compliant postage and shipping labels without visiting a post office. The service supports all USPS domestic and international products — first-class letters and flats, Priority Mail, Priority Mail Express, Parcel Select, and international customs forms. Users can print directly to thermal or laser printers and can create shipping labels in bulk using CSV imports or connected marketplaces.
Beyond label printing, Stamps.com includes address verification and correction to reduce undeliverable mail, rate comparisons among USPS services, and automated customs documentation for international shipments. The system also manages postage account balances, displays transaction histories, and provides daily postage and shipping reports for accounting and audit purposes.
For operations with recurring shipping needs, Stamps.com supports batch label creation, scheduled postage purchase, and manifest generation. Integrations with popular e-commerce platforms allow orders to flow into Stamps.com automatically; tracking numbers and fulfillment status can be written back to the marketplace to maintain order lifecycle visibility.
Stamps.com also provides features for regulatory and business needs: return label creation and management, commercial pricing access for qualifying shippers, and options for insurance and signature confirmation. For higher-volume customers, the platform offers enhanced account and administrative controls, including user role management, activity logs, and consolidated billing.

Cons:
Stamps.com commonly offers a limited free trial for new accounts so users can test postage purchasing, label printing, and marketplace integrations before committing to a paid subscription. Trial lengths and features included in the trial vary by promotion and time; trials usually allow printing a limited number of labels or offer a time-limited window (for example, 4 or 30 days).
The trial is useful to validate printer compatibility, ensure integration with your marketplace or e-commerce platform, and test the reporting and reconciliation workflows. During the trial you can confirm that USPS commercial rates and postage fee flows meet your business needs.
To start a trial, create an account on Stamps.com and follow the onboarding steps; for current offers and trial durations see Stamps.com's promotional page and signup flow.
