Why teams leave Sellsy
What your team gets in Atome.
Manage emails as a team
Share a mailbox with your team, and each email is saved on the client and the deal it concerns. In Sellsy, each person syncs one mailbox.
Add the tables your business needs
Orders, projects, suppliers or properties, each linked to its clients. Sellsy adds custom fields to its own records, ten on the first plan.
More than a CRM
Call transcripts, automations, forms, views, and so much more.
Manage emails as a team
Email: Gmail and Outlook, shared inbox, campaigns
Every email is saved on the client and the deal it belongs to, for the whole team.
Book clients into your team calendar
Calendar: Google and Microsoft sync, team calendars, scheduling
Clients pick a time from your scheduling link, and the meeting is saved on their record and their deal.

AI notetaker: transcript, summary, next actions
Atome records the call with a client, saves the summary on their record and lists the next steps.
Write notes and docs
Docs: notes, proposals, meeting briefs

Enrich every company you add
Enrichment: company and contact details filled in
Add a company's website, and Atome fills in its industry, size, location and LinkedIn.

AI brain: full context on all your data
Ask which clients have not replied in two weeks. The AI answers from your emails, meetings and files.
Chat about each client
Each client and each deal has its own chat thread for the team.
Automate repetitive work
A deal moves to the next stage, and Atome sends the email and creates the tasks.
Collect leads with forms

Fits better if
Atome

FAQs
Questions about the switch.
Can we keep Sellsy for invoicing?
Yes. Atome holds the clients, deals, emails and meetings, and your invoices stay in Sellsy.
Have you migrated teams from Sellsy before?
Our team has migrated teams from Pipedrive, HubSpot, Airtable, Odoo and spreadsheets, with tools we built for switching from an old CRM. For Sellsy, we look at your account with you before anything moves.
Do our emails come over?
Your emails come from your mailbox. When you connect Gmail or Outlook, you choose how much past email Atome brings in, and each thread is linked to its contacts and companies.
How long does the switch take?
It depends on your pipelines and your data, so we do not publish a duration. Tell us on the demo how your Sellsy is set up.
Who does the switch?
Our implementation team, with you: planning the switch, migrating your data and training your teams.
Where is our data hosted?
In the European Union. Servers and file storage are provided by UpCloud, and the database by Aiven in Germany. Atome AI runs on Mistral AI in France, and on European servers through Cortecs in Austria. The sub-processors page lists every provider.
How much does Atome cost?
€49 per member per month, excluding VAT, billed yearly, or €59 billed monthly. Each member gets a monthly AI allowance.
