Is using Eridia compatible with professional secrecy?

Eridia is designed to help you uphold it: you choose where data is processed (France-hosted cloud, private cloud or your own servers), access is managed per user and every action is logged. Your clients' data is never used to train models.

Does Eridia work with our accounting software?

Eridia works from the exports every accounting package produces: FEC files, trial balances and general ledgers in Excel or CSV, returns and statements in PDF. Connectors also give access to your document repositories. For a deeper integration with your tool, we review the need with you.

Where is our data hosted?

Wherever you decide: on the France-hosted Eridia cloud, in your private cloud or directly on the firm's servers. In the last two cases, files never leave your infrastructure.

How much does Eridia cost for a firm?

Pricing is quoted based on the number of users and the deployment mode. The subscription includes all models, with no usage-based billing.

How long does it take to get started?

On the France-hosted cloud, the firm can start within a few days. An installation in your private cloud or on your servers is planned with you depending on your infrastructure. In every case, onboarding of your staff is supported.

Why firms hesitate to use consumer AI

Professional secrecy covers every file

The profession's statute and code of ethics require secrecy on everything clients entrust to you. Pasting a trial balance or an FEC file into a consumer tool means handing that data to a third party whose hosting and usage you don't control.

Tax season leaves no slack

From January to May, year-end accounts, tax returns and client meetings pile up. Every hour spent rereading a general ledger or drafting a summary note is an hour taken from review and advisory work.

Fewer staff, just as many files

Firms struggle to hire and junior staff need to get up to speed fast. The same tax and payroll questions keep coming back, and partners don't always have time to answer them.

What Eridia brings to your firm

Concrete uses, from account review to client meetings.

File summary from the trial balance and FEC

Import the trial balance, FEC or general ledger as Excel or CSV: the AI flags significant year-on-year variances, accounts to substantiate and unusual entries, then drafts a first summary note that your staff checks and completes.

Significant year-over-year variances

Year-end meeting preparation

From the annual accounts, the tax return and the file history, the AI prepares a meeting brief: key figures, margin and cash trends, topics to raise with the business owner.

Sourced answers to tax and payroll questions

A staff member asks about a VAT regime, an exemption or a payroll rule: the answer draws on official texts (Légifrance, BOFiP) and your internal notes, with sources cited for verification.

Eridia

Yes, under conditions

Principle: mileage allowances reimburse actual costs. They come on top of salary if trips are business-related and documented.¹
Evidence: date, route, purpose and mileage of each trip, and a registration document in the manager's name.²
Rates: official mileage scale published every year by the tax authority, based on the car's fiscal horsepower.³
