⭐18 Invopop: Global E-invoicing
3 min read - Issue compliant invoices, globally 🧾💻🌍
Scaling your business means working with invoices that need the right compliance. Invopop, a seed company based in Madrid, makes it simple with one powerful API that converts sales into locally compliant invoices and files them directly with the right tax authority.
🔍 The Problem
Electronic invoicing is becoming the norm — and a major headache. More and more countries now require businesses to issue invoices in specific formats and report every sale to tax authorities in real time.
⚠️ The problem? Each country does e-invoicing differently.
Formats, rules, and systems vary wildly across borders. What works in Spain won’t fly in Colombia or Italy. For companies operating in multiple markets, this creates a growing compliance burden.
Finance and engineering teams are forced to navigate a maze of evolving local requirements — and staying compliant isn’t just time-consuming, it’s risky if done wrong.
🔬 The Solution
It all started with a simple idea: Wouldn’t it be great to send all invoices to one place and have someone else handle the compliance? 💡
🧰 Enter Invopop: a developer-friendly, API-first platform that transforms standard invoice data into whatever local format is required — automatically, in real time. 🪄
Instead of rebuilding integrations for each country, companies connect once to Invopop’s API.
The platform handles the heavy lifting:
✅ Converts invoices into each country’s mandated format
✅ Sends them to the tax authority as needed
Who’s it for?
🏪 Point of Sale providers – Companies that offer checkout systems to merchants. Invopop helps them issue tax-compliant receipts and invoices across regions.
💳 Payment platforms – Support global expansion while staying tax-compliant
🌍 Multi-country businesses – Avoid building and maintaining custom tax logic in every market
📈 Market Potential and Scalability
As many as 40 countries already enforce some form of mandatory e-invoicing or real-time invoice reporting, and over 20 more have laws taking effect in the next few years. In the EU alone, all member states are planning to require businesses to issue and report invoices electronically in real time.
Electronic invoicing is quickly becoming the global standard.
🌏 The global e-invoicing market is projected to grow to $55 billion by 2029, at a compound annual growth rate of 23.6%, with countries like Mexico, Brazil, Spain, and Germany leading the regulatory wave.
💡Given the worldwide shift to e-invoicing, Invopop’s globally unified approach could ride a long wave of demand as more countries make digital compliance mandatory.
🚀 Stage
🎓 Invopop was founded in 2020, participated in Y Combinator (Winter ‘23), and raised a €2.2 million seed round.
👥 With a lean team, they already support 40 core clients — including some platforms that serve over 2,000 companies, who now issue more than 200,000 compliant invoices each month through Invopop.
🖨️ By the end of the year, they expect to cross 1 million invoices/month, driven by global software providers embedding invoicing into their platforms.
💸 The business model is usage-based: clients are charged per invoice, with pricing ranging from €0.005 to €0.30 depending on volume.
📈 And while the company has a solid runway, its traction suggests a larger raise may be on the horizon to scale faster into new countries and verticals.
👥 Founder Team
Invopop was co-founded by Juan Moliner and Sam Lown.
🤝 Juan, a former BCG consultant, witnessed the inefficiencies of invoice compliance firsthand while working in Latin America.
💻 Sam, previously the CTO of Cabify (Spain’s first tech unicorn), ran into this issue at scale while expanding operations globally.
Their combined insight led to a clear conclusion: global invoice compliance needs to be rebuilt from the ground up — with developers in mind. That’s what Invopop delivers: modern infrastructure for the next era of cross-border business.
