Una plataforma de facturación medida plug-and-play específicamente diseñada para startups SaaS con modelos pay-per-use, que incluya APIs simples, dashboard de gestión y pricing flexible.

I’m building a SaaS product with a pay-per-use model (e.g. $1 per API request) and need to set up billing so I can start charging customers. I want a billing solution that’s quick to implement, lean, and doesn’t eat into my margins.<p>I know Stripe is a common choice, but building a fully custom billing system isn’t feasible for me right now. I’m hoping to find something I can drop in with minimal code and effort that covers the basics.<p>Here’s what I need:<p>Customers can: Set up and update payment methods. Track their usage during the billing period. Download invoices.<p>I can: View customer usage and past&#x2F;upcoming invoices. Adjust pricing (e.g. volume discounts).<p>I’d love to hear from others who’ve tackled this. What tools or services worked for you?<p>Bonus points for developer-friendly, budget-conscious solutions that won’t make me regret not doing it myself!
