Hey everyone! I'm Rob and I want to share what I've built - a solid ledger behind simple API: https://decimals.app The ledger is a key piece of any financial system and is easy to get the design wrong, resulting in troubles for making sure money movements are adding up. I took a lot of inspiration from good designs from Square, Uber, and others for the scalability and security aspects. And on the usability side, I applied many concepts from the Ledger CLI, making it very easy to use. I'm really happy I get to show this to you all, thank you for reading about it! Please let me know…

I'm a solopreneur and I made it very easy to integrate a credit system into your apps and games using Creduse. I built Creduse because more and more users want pay-as-you-go models, and founders need new ways to increase user engagement or nicely limit cost-intensive features (see AI). Creduse is built by a developer for developers. I hope it will help as many startups as possible. Feedback are very much appreciated. Francesco

Hello HN Community, As an ex-founder of a developers-for-hire agency, I was fortunate to build for many different software organizations around the world, and partner with the most talented product teams. One of the things I learned by coding was how painful it is to build & maintain pricing in SaaS. The pricing structure and logic always end up being coupled with the core application code and the billing platform. The product catalog is typically managed in spreadsheets, by the product & monetization teams, while all the possible package types, including the legacy ones, are typically…

Hey HN: I'm Kaveh, the founder of Usage (https://www.usage.ai/) We help companies drive down AWS costs. Why? Because the way it's done now is a pain. Stakeholders, especially engineers, are required to spend unnecessary time manually finding underutilized or overly expensive EC2s. We believe the optimization process should be done automatically through a series of sophisticated algorithms. At the moment, there are over 70,000 AWS EC2 prices - doing that manually just won't scale at most organizations. My background is in software engineering. Previous to founding Usage, I…

Hey HN, we’ve been working on a way to simplify authentication with third-party APIs. This started because my co-founder andreterron (https://news.ycombinator.com/user?id=andreterron) and I both built personal dashboards to track different health and productivity metrics, but it’s such an annoying chore to integrate with new APIs. First you read their docs to learn their authentication method, then build and deploy a custom server to receive OAuth callback requests or deal with CORS, register an app with them, then finally you can send the first request to their API. After the…

After a lot of personal hardships over the past year, I can finally say that InvoicingAPI is ready for public use. It's a platform where you can create beautiful, customizable and dynamic, tax-compliant invoices with payment links built in, so your clients pay you faster. In your dashboard you can see your payments and payouts to your bank. This is just an initial release and plenty of features are in the pipeline, like an online builder, automated sending, 3rd party app integration, etc. Feel free to poke around and let me know your thoughts!

Hi everyone, I've been working on a side project over quarantine called Usage.ai and I finally feel comfortable enough to launch it. We're a service that plugs directly into AWS, automatically finds savings, and applies those savings at the press of a confirmation button all without ever needing to go to an AWS console. I'd love to get HN's thoughts on it! Demo: https://www.loom.com/share/2a6f1c8e4c214914a1cdd88c6fdec4ac Link: https://www.usage.ai/

Hey HN, I’am Koshima, co-founder of Flexprice (https://flexprice.io/). Flexprice is an open source monetization platform for AI & Agentic companies. You can build usage-based, credit-based, or hybrid pricing models with full control. Usage-based billing works on paper, but breaks fast in production: (1) High-volume data (e.g., 10k API calls/sec from AI inferences) breaks naive pipelines, dropping events and causing underbilling or customer complaints. (2) Backfilling missing events or retroactive discounts screws up invoices, forcing 3 AM log stitching to avoid revenue…
