Memberships can provide a content library with billing periods including monthly, quarterly, biannually, and yearly. Digital product support includes PDF, ePub, and Mobi versions, plus generated software license keys and lightweight DRM. Creators can import email lists, export follower and customer details, send broadcasts, and create automated workflows. Sales analytics and tracking support Google Analytics, Meta Pixel, and TikTok Pixel. Gumroad also provides an API and buyer apps for Android and iOS. Payout methods vary by country; direct deposit or PayPal may be available. The maker says it handles worldwide sales-tax collection and remittance as merchant of record. Direct sales cost 10% + $0.50 per transaction; Discover sales to new customers cost 30% per transaction.

Polar is a billing stack for AI products, combining subscriptions, usage billing, credits, invoicing, and merchant-of-record services. It collects usage events into customer meters and adds metered charges to the next invoice. Meters can count, sum, average, find minimums or maximums, and track unique values. Usage collection options cover LLM activity, streaming responses, S3-compatible storage, elapsed time, and manually submitted events; LLM integrations include the Vercel AI SDK and compatible models that return usage data. As merchant of record, Polar says it resells products in over 100 markets and handles payments, sales tax, fraud, refunds, and chargebacks. Its hosted checkout supports localized currencies and includes sales tax. Automated benefits include usage credits, license keys, file downloads up to 10GB, and invitations to private GitHub repositories and Discord. Polar lists apps for iOS and Android and plugins for Raycast and Framer. The Starter plan is free; Pro is $20/month, Growth is $100/month, and Scale is $400/month, with transaction fees on each plan. Usage meters do not block activity when a quota is exceeded; the product using Polar must enforce limits.
