GLOBAL E-INVOICING COMPLIANCE · RAINDROP SYSTEMS
ONE API,
EVERY MANDATE
Global, automated tax compliance for every market.
Global e-invoicing compliance software should do one thing well: keep every invoice valid in every market you operate in, without a new project every time a country changes its rules. Raindrop Systems connects your existing ERP, accounting, and commerce systems to tax authority platforms, the Peppol network, the U.S. DBNA network, and local country networks through one API, with real-time reporting built in from day one.

THE ARCHITECTURAL CHOICE
One API, Many Mandates
This is the architectural choice that separates a real global platform from a stitched-together patchwork of country-specific vendors. Most e-invoicing approaches require a new integration, a new contract, or both, every time you enter a market with its own rules. Raindrop Systems works differently: one API connects once, and new countries activate on top of that same connection, with no second integration project, no new vendor contract to negotiate. The API you connected on day one is the same API that carries you into country 50.
Adding a new country mandate doesn’t require a developer, a professional-services engagement, or a re-opened IT ticket. An administrator activates a new mandate through a wizard-guided interface: select the country, confirm the applicable compliance model, and go live. Regional and country-specific compliance vendors typically require a separate contract and separate integration for every market. Legacy procure-to-pay suites tend to bolt e-invoicing on as an afterthought, a compliance checkbox rather than a core capability. Neither approach scales the way a global finance team needs it to.

Secure by Design
SOC 2 Type II certified, covering data handling practices and access controls at the standard finance and IT teams expect.
Built to Last: ERP-Agnostic and Future-Proof
Your ERP will change eventually. Mandates will change constantly. Any tax compliance automation that can’t absorb both isn’t a platform. It’s a liability waiting for its renewal date.
The single API works in the background of whatever ERP, accounting, or commerce system you already run. It doesn’t require ripping out existing workflows or retraining your AP team on a new interface just to stay compliant. Raindrop Systems’ E-Invoicing module sits alongside your current stack rather than replacing it.
Tax authorities don’t pause for your budget cycle. When a country updates its e-invoicing requirements, the platform adapts without a re-integration project on your side. That’s where Rain comes in: Rain, Raindrop Systems’ AI agent, continuously monitors mandate changes across every market you’re connected to, flagging what’s coming before it’s due. Proactive compliance instead of reactive scrambling, and one less thing your tax team has to track manually across dozens of jurisdictions.
For tax teams specifically, this means advance notice ahead of a new mandate taking effect, not a scramble after an audit or a rejected invoice reveals a problem. Legal and compliance leaders get the same benefit from a different angle: real-time tax authority reporting across clearance, live-reporting, and CTC models, plus no-code activation that reduces how often compliance changes require pulling IT into the loop.
Compliance Models, Explained
E-invoicing mandates aren’t one thing. Global e-invoicing compliance software has to account for four broad models, and knowing which one applies where you operate changes how you plan for it. One platform, one API, and Rain tracks which model applies in every market where you operate today, plus where new mandates are headed next. You don’t need a separate playbook for each one.
Clearance Model
A government authority pre-approves each invoice before it’s legally valid. Nothing moves until the invoice clears.
Common across Latin America
Live Invoice Reporting Model
The invoice gets reported to the tax authority at or near the moment it’s issued, without a pre-clearance step.
Hungary and Spain
Centralized Issuance Model
A national platform issues or routes invoices through a shared network.
Peppol e-invoicing across the Nordics
Decentralized CTC
Continuous transaction controls apply without a single central platform doing the routing.
Italy and Poland-style regimes
Secure by Design
Global tax data moving across dozens of jurisdictions needs to be handled carefully, not just quickly. Raindrop Systems’ E-Invoicing module is SOC 2 Type II certified, covering data handling practices and access controls at the standard finance and IT teams expect from any platform touching regulated financial data. For legal and compliance leaders, that’s lower regulatory and audit risk without adding headcount to manage it.
From Compliant Invoice to Paid Invoice
An e-invoicing platform isn’t a standalone compliance tool sitting off to the side of your finance stack. It’s the entry point to the Source-to-Pay (S2P) suite, and that’s the whole point.
On Raindrop Systems’ own numbers, automated invoice processing runs 72% faster than manual handling, and more than 35% of invoices process straight through without anyone touching them.
Once an invoice clears compliance, structured data (not a PDF, not a scanned image) flows directly into AP Automation for matching and approval. That handoff matters more than it sounds. One medical device manufacturer using Raindrop Systems saw a 76% reduction in invoice cycle time and 56% touchless processing once structured e-invoice data started flowing downstream into AP Automation. That’s a downstream result of structured data feeding AP Automation, not an E-Invoicing-specific case study on its own.
From there, approved invoices move to payment through RainPay, closing the loop from compliant capture to processed approval to executed payment. For procurement and finance teams, that means structured invoice data replacing paper and PDF billing entirely, with real-time visibility across every market you operate in. For executives, it means lower cost per transaction and no constant re-integration tax every time the business expands into a new country. The invoice doesn’t just get compliant. It gets paid.

Different roles need different things from a global e-invoicing platform, and it helps to know where to look first.
If you lead finance or AP operations, see how finance teams use Raindrop Systems day to day, from invoice intake through payment execution. If you own ERP integrations or sit on the compliance side, see how IT and compliance teams work with Raindrop Systems across security, access controls, and mandate management. Both paths start from the same platform, they just answer different questions first.

FAQ
Most e-invoicing vendors require a new integration project for every country, or bolt compliance onto a legacy procure-to-pay suite as an afterthought. Raindrop Systems uses one API that expands to new mandates through no-code, admin-driven activation, so growth into a new market doesn't restart the integration clock.
Raindrop Systems' E-Invoicing module supports 200+ countries and territories and 140+ currencies, spanning clearance, live reporting, centralized issuance, and decentralized CTC compliance models. See the Compliance Models, Explained section above for how each model works.
The platform connects through a single, ERP-agnostic API that works in the background of your current ERP, accounting, or commerce system. It doesn't require replacing existing workflows or retraining your team on a new interface just to stay compliant.
Rain, Raindrop Systems' AI agent, monitors mandate changes continuously across every connected market. When a rule changes, updates apply through the same no-code activation flow an administrator already knows, not a new IT project or professional-services engagement.
Building in-house means maintaining per-country compliance logic against a regulatory target that never stops moving, indefinitely, with your own engineering team absorbing every mandate change as it happens. A platform built for this problem carries that maintenance burden instead of your team.
Four models: clearance (government pre-approves each invoice, common across Latin America), live reporting (invoice reported near time of issuance, as in Hungary and Spain), centralized issuance (a national platform routes invoices, as with Peppol-based Nordic systems), and decentralized CTC (continuous transaction controls without one central platform, as in Italy and Poland-style regimes).
Structured invoice data moves from E-Invoicing into AP Automation for matching and approval, then to RainPay for payment execution. It's one continuous flow from compliant capture to paid invoice, not three disconnected tools you have to stitch together yourself.
Raindrop Systems' E-Invoicing module is SOC 2 Type II certified, covering data handling practices and access controls. See the Secure by Design section above for what that certification covers in practice.
Rain, distinct from the Raindrop Systems platform itself, continuously monitors mandate changes across every market you're connected to. That's a proactive compliance posture: flagging what's coming before a deadline hits, rather than reacting after a rule change causes a rejected invoice or a missed filing.
