The demo “Invoice” template: Carbone tags are filled with data from the demo database.

An author prepares the template

A template is an ordinary Word or Excel document with tags like {d.company.name}. It opens in the built-in OnlyOffice editor — no Word or Excel needed.

Data comes from SQL queries to connected databases. Queries run read-only, and report parameters are passed into them by name.

join invoices i on i.company_id = c.id
where i.id = :invoiceId

A user generates the report

Reports are grouped into categories; everyone sees only what they have access to.

The run form is built from the template's parameters: dates, numbers and lists, including dependent lists from SQL queries. Generated reports stay in the history: open them again, download them in another format or sign them later.

Signing and control

A PDF is signed with the user's certificate (.p12) or with a GOST key via CryptoPro — the GOST key never leaves the user's computer. PDFs can get a watermark, page numbering and standing attachments; PDF/A and password protection are available too.

Access is granted by groups and categories; roles separate users, template authors and access managers. Sign-in uses local accounts, LDAP/Active Directory or Keycloak (OpenID Connect).
