Invoiceocean has security features similar to banking systems. Access to the User's account is possible only after entering the login and password, and the program itself is encrypted and secured with an SSL certificate. Only a few employees of InvoiceOcean have access to the data and each of them has a signed confidentiality agreement.  Data backup is created on an ongoing basis so that, even in the event of a failure - your data will not be lost. For more information on data security in the system, see the Safe invoicing article.
