Three steps from quote to signature.
Synced from 11 ERP systems or uploaded as PDF — in seconds.

Legally binding under ZertES, with timestamp and audit trail. Your ERP updates automatically.
Three legal frameworks shape how Swiss businesses operate. ATHEMI is built around them from the ground up.
Accounting records, supporting documents, and business correspondence must be retained in Switzerland for 10 years — in writing or electronically — and available within a reasonable time at any point.
Centrally archived, searchable, independent of individual employees.
Requires appropriate technical and organizational measures to protect personal data — and full transparency about who has access.
Encrypted transmission, granular access rights, complete audit log, hosted in Switzerland.
Defines when an electronic signature is legally equivalent to a handwritten one. For most business agreements the simple electronic signature is sufficient — and admissible as evidence — provided the signer and timestamp are verifiably documented.
Identity verification, timestamp, integrity-protected document.
Note: contracts requiring formal written form (e.g. requiring a qualified electronic signature) have stricter requirements. Happy to advise.
When business documents live in personal email accounts, they live with that one individual. When the employee changes jobs, quotes, agreements, and contracts often become unreachable. With ATHEMI, every project is a shared space owned by the company. Employees come and go — the data stays.

No ERP? That works too — ATHEMI runs standalone.

Three commitments that make the choice easier.
Complete export anytime as ZIP — documents, communication, signatures. No lock-in.
Cancel monthly. The free tier stays free.
Hosted in Switzerland, Swiss data protection law, no data leaves the country.
Quick answers to the most common questions.
Yes. ATHEMI uses the simple electronic signature under ZertES, with identity verification, timestamp, and integrity-protected document. For most business agreements — quotes, order confirmations, service agreements — that's sufficient and admissible as evidence. Contracts requiring formal written form have stricter requirements.
In Switzerland. ATHEMI is hosted by Infomaniak, a Swiss provider with data centers in Switzerland. Your data does not leave Switzerland. Daily backups are also stored on Swiss infrastructure.
You can export all project data as ZIP at any time — documents, communication, signatures, timeline. No lock-in, no loss. After cancellation, your data is deleted according to our privacy policy; the export remains available until then.
