Credyt▲100Hey HN! I'm the founder of Credyt (https://credyt.ai). If you're running an AI product that burns $0.50+ per interaction, you need to bill customers as usage happens, not at the end of the month. Otherwise you're a bank for your customers, and you'll run out of money before they do. Why invoice-based billing doesn't work for AI: Most usage-based billing tools (Stripe Billing, Orb, etc.) were built for SaaS. They meter usage all month, then send an invoice. That works fine when your COGS is 5%. It's a disaster when you're paying your AI vendor upfront for every request and your…

ParityDeals keeps that billing logic out of your app. Once you integrate ParityDeals SDK, you can manage everything from a single dashboard. No further code changes required. I'd love to hear your feedback

Hi HN! We’re building an open-source pricing & packaging engine for SaaS with a built-in billing system. (https://github.com/uselotus/lotus). We strongly believe pricing is the largest untapped growth lever for SaaS, primarily because pricing affects so many critical systems that don’t talk to each other (billing, payments, feature limits, metering, and CRM). We’re building this infrastructure to fix this and enable quick experimentation. Lotus acts as a central repository for all of your pricing plans and utilizes your payment gateway, to manage usage-based, per-seat,…
