Exchanging documents with clients doesn’t have to be complicated
As an accountant, accounting firm or tax advisor, you deal with collecting, sharing and approving important documents every day. Think of annual accounts, engagement letters, SBR reports and tax returns.
In practice, this often means lots of emails, separate files, sending reminders and waiting for a signature or approval from the client. Meanwhile, those same clients expect fast, digital service.
With a modern digital signing solution, you can bring these processes together in one environment. Clients can securely receive documents, easily sign them and submit them directly through a user-friendly platform, while employees have access to complete audit logs and up-to-date status information. This helps you complete client files faster.
For accounting firms, digital signing is not only about convenience, but also about control and compliance. Especially for processes involving tax returns, annual accounts and SBR reporting, it is important to have a clear record of who took action and when. With PKIsigning, you work more efficiently, gain greater control and improve the client experience.
