Products that do what Custom Pricing Units in Flexprice (price in credits, bill in USD) does
Hi HN, working in the monetization field, we kept seeing the same problem. Product teams want to price in credits or tokens. Finance wants clean USD accounting. Engineering ends up stitching conversion logic across services, and over time rounding errors, inconsistent invoices, and reconciliation headaches creep in. So we added Custom Pricing Units to Flexprice! You can now define your own unit (e.g. CRD), attach a conversion rate to a base currency (like USD), and use that unit across plans, recurring charges, usage pricing, and wallets. Customers see and are charged in credits. Flexprice…

If you sell credits or tokens, at some point someone asks: “What is one credit actually worth?” We shipped explicit Wallet Conversion Rate controls in Flexprice to answer that cleanly. Each wallet can now define: • conversion_rate — how credits map to currency when spending • topup_conversion_rate — optional rate used only when adding credits This supports use cases like promotional top-ups, bonus credits, or discounted purchases while keeping invoice calculations consistent. Wallets store credits.Invoices remain in a single base currency. Conversion defines the relationship between the two.…

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…

Hey HN! Christine and Steven here. As a PM and engineer, we’ve both evaluated and purchased a lot of software. One of the biggest frustrations was figuring out how much it would cost us without having to go through the sales process. When we did have a quote, we had no idea if we were getting a good deal or ripped off. We built a site where you can see what other companies are actually paying for SaaS and enterprise software. Buyers contribute prices via quotes, pricing proposals, and other documentation to ensure quality. We unlocked Talkdesk for Show HN users so that you can use the…

The LLM providers are constantly adding new models and updating their API prices. Anyone building AI applications knows that these prices are very important to their bottom line. The only place I am aware of is going to these provider's individual website pages to check the price per token. To solve this inconvenience I spent a few hours making pricepertoken.com which has the latest model's up-to-date prices all in one place. Thinking about adding image models too especially since you have multiple options (fal, replicate) to use the same model and the prices are not always the same.

Hi HN, I built Small Transfers, a payments platform for SaaS / API makers who want to bill customers per request instead of pushing them into subscriptions or pre-buy packages. *Why?* - Many customers hate subscriptions and/or want to use a service occasionally. - Traditional payment processors add a fixed fee to every charge, making charges below 1 USD impractical. - Stripe UBB tracks usage, but you still need to write your own auth, add spending limits, and each merchant charges cards separately (extra fees for customers). *How it works?* - Each merchant has a Small Transfers…

Hi HN, We just shipped a Nomod integration in Flexprice. For context, flexprice is an open-source billing system that handles invoices, usage, and credit wallets. One gap we wanted to close was supporting region-specific payment providers without breaking billing state. With this integration: - Invoices finalized in Flexprice can be synced to Nomod - A hosted Nomod payment link is generated for the invoice - Payment status updates flow back into Flexprice - Invoices and payment records stay in sync - Credits (if applicable) are applied only after payment succeeds This keeps billing logic…

Hey HN, A recurring problem we kept running into with billing systems was the human layer around them. Customers asking: “What’s my current balance?”“Which invoice is pending?”“Why did usage spike last week?”And the answer was usually someone digging through dashboards, exporting PDFs, or pasting screenshots. So we built a read-only customer billing portal inside Flexprice (open-source metering + billing infra). It gives customers visibility into: subscriptions and billing periodsprepaid wallet balances and credit transactionsinvoices (status, search, download)feature-level usage and cost…
