Cloud Integrations: R2, SMTP, KSeF
Connecting your own infrastructure: file storage, mail server, and KSeF.
On higher-tier plans, you can connect your own infrastructure instead of the built-in one.
Where to find it
Settings → Cloud Integrations (…/erp/integrations).
Custom Storage (S3/R2)
Workspace files are stored in your bucket (Cloudflare R2, Amazon S3): full control over data and no tariff storage limits. Enter your access keys and bucket name.
Custom SMTP
Mailings are sent through your mail server from your domain — critical for deliverability of large volumes.
KSeF
Integration with the Polish e-invoicing system KSeF — invoices are registered in accordance with legal requirements. Access data is provided by your accountant/KSeF administrator.
