What Rillet is built for
Rillet calls itself "The AI-Native ERP" and, more recently, "The Agentic ERP", with the hero line "Zero-Day Close" and the claim that it "was built by accountants, for accountants". Its own machine-readable index describes the target as SaaS companies with 100 to 1,000 employees, typically Series A to C, with healthcare tech, fintech and developer tools alongside, and the site states "800+ customers in 70+ countries". Founded in 2021, Rillet has "raised over $200M from Sequoia, a16z, and ICONIQ", with offices in San Francisco and New York. The platform is built around an automated general ledger with "flexible GAAP reporting", native ASC 606 revenue recognition, SaaS metrics computed from the ledger, multi-entity consolidation with automated intercompany eliminations and multi-currency, close checklists and a "Launchpad" dashboard. Multi-book allows a consolidated US GAAP view with "Up to 5 secondary books per org" for IFRS or tax. Aura AI is described as "The agent that reasons like an accountant" with the instruction "Approve and edit every step", and Aura Flows as a model in which "agents propose, humans approve". Rillet publishes EU bank feeds through Plaid in fourteen countries including Germany, with Switzerland and Austria not listed, live tax for UK VAT, Australian GST and Canadian GST/HST, a REST API and a remote MCP server, a "4-6 weeks" white-glove implementation, pricing that is not per seat, and SOC 1 and SOC 2 Type II with hosting on AWS.
What Aderis is built for
Aderis is the Live Finance Platform: a finance system of record that runs accounting autonomously on an AI-native core, keeps every number traceable to source and orchestrates the full finance cycle across entities, ledgers and currencies in real time. It is built in and for Switzerland and Europe for growing mid-market companies with multi-entity, multi-currency or multi-country structures, with offices in Kilchberg, Munich and Vienna. Swiss banks connect directly through bLink from SIX, ISO 20022, the QR-bill and CAMT are supported natively, data is hosted in Switzerland and the EU, and the platform is designed to meet GeBüV and GoBD requirements.
Where they are alike
At first glance Rillet and Aderis look similar, and in a traditional ERP comparison the usual distinction between an existing system with AI extensions and an AI-native platform would not apply to either of them. Rillet's general ledger processes financial events continuously and its Aura agents work directly on that foundation; Aderis follows the same architectural principle, with AI in the Core rather than as an add-on. Both run multi-entity, multi-currency and consolidation on the same platform, both expose an API and an MCP server, and both describe the close as continuous rather than a month-end event. The relevant difference lies one level deeper.
Where they differ
How far autonomous execution goes. At Rillet, agents work on a propose-and-approve model: they prepare postings and actions, log their steps and submit them to the finance team for approval before anything posts. Aderis also defines the rules before execution, but shifts a larger part of the control into the rules of the platform. The CFO and the finance team define permissions, thresholds, approvals and escalations in advance; within that frame agents execute recurring processes autonomously, and only exceptions or cases outside the rules go to a person. Rillet places human approval before the posting; Aderis places human control before the rule and on the exception.
Geography and compliance. Rillet comes from the US finance environment: its reference points are US GAAP, ASC 606 and the processes of SaaS companies, with UK GAAP, IFRS and Making Tax Digital documented for the UK. Its published material contains nothing on Swiss GAAP FER, HGB, UGB, Swiss, German or Austrian VAT returns, GeBüV or GoBD, German-language support or DACH customers. Aderis is built for that region from the outset, with statutory, tax, management and group ledgers in parallel, VAT reporting in the Core, GeBüV and GoBD readiness and offices in all three DACH countries.
Banking. Rillet documents EU bank feeds through Plaid, with Germany among the fourteen countries and Switzerland and Austria not listed; a direct connection to the Swiss banking infrastructure is not publicly stated. Aderis connects Swiss banks directly through bLink, with payment submission and account information in the same finance process, and supports ISO 20022, QR-bill and CAMT natively.
Ledgers. Rillet's multi-book keeps a US GAAP consolidated view with up to five secondary books per organisation. Aderis records a transaction once and carries it simultaneously into statutory, tax, management and group ledgers from a single posting base, which is what a European group has to run in parallel.
Data residency. Rillet is hosted on AWS and documents GDPR commitment; a Swiss or EU residency option is not published. Aderis hosts customer data in Switzerland and the EU.
Implementation. Rillet quotes four to six weeks with a white-glove team that includes CPAs. Aderis runs migration as a service measured in days, with master data, opening balances and history transferred and included.

Which fits which company
Rillet fits a strongly US-oriented company whose finance organisation works to US GAAP, where SaaS and subscription revenue make up a large part of the business, ASC 606 and revenue recognition are central to the finance system, the control model requires agents to prepare actions that are approved before execution, and the system landscape is built on typical US SaaS and fintech applications. Aderis fits a company whose finance function runs in Switzerland, Germany, Austria or several European markets, where local accounting and banking requirements are a selection criterion, several entities, ledgers, currencies and jurisdictions are managed together, banking is to be integrated into continuous finance processes, agents are to execute defined tasks autonomously within built-in rules, and data residency in Switzerland or the EU is part of the governance requirements.
Frequently asked questions
Are both platforms AI-native?
Yes. Both process financial events continuously in the ledger with agents working on that foundation. The difference is the control model (approve each step versus execute within rules) and the financial reality each was built for.
Does Rillet support Swiss banking or Swiss statutory requirements?
Rillet publishes EU bank feeds through Plaid, with Switzerland and Austria not among the listed countries, and nothing on Swiss GAAP FER, Swiss VAT returns, QR-bill, CAMT, GeBüV or GoBD. A direct connection to the Swiss banking infrastructure is not publicly stated.
Where is data hosted?
Rillet is hosted on AWS with a GDPR commitment; a Swiss or EU residency option is not published. Aderis hosts in Switzerland and the EU.
