Designed with and for demanding teams
3-in-1
Stop paying for Front, Zendesk and Zapier separately. OneBoxflow does all three — better integrated, hosted in Europe.
Shared mailboxes (contact@, sales@, support@), assignment, real-time presence, collaborative drafts, mute, snooze.
Tickets, SLAs, macros, canned responses, automatic escalation, post-resolution CSAT. Without switching tools.
No-code rules, documented REST API, HMAC-signed webhooks, official WordPress plugin. Plug your CRM in one afternoon.
Three pillars, one platform
It's an enterprise platform that integrates, proves itself and stays governed.
Assignment, statuses, SLAs, real-time presence. Never again two people replying to the same contact@ thread.
Documented public REST API, HMAC-signed webhooks, SDK and SCIM. Plug OneBoxflow into your CRM or ticketing in an afternoon.

Adaptive AI triage
Three triage layers in cascade: rules handle the easy part, AI only decides on ambiguous cases. Fix it once, the system learns forever.
Domain, sender, headers. Free, instant, deterministic.
Weighted keywords (invoice, registration, webinar…). No AI call.
Only on ambiguous cases. Each decision becomes a reusable rule.
Engine: Google Gemini 3 Flash via Lovable AI Gateway. Controlled cost, full transparency.
Mails, appels, WhatsApp, mémos vocaux, réunions — un seul fil par personne. Tes notes, ton contexte projet, tes curseurs de confiance. L'IA s'en sert, elle n'y touche pas.
