Easy-to-Use Client Portal Software

A secure client portal is great – if your clients will actually use it.

We see lots of accounting firms invest in fancy new software or other tools with the best of intentions, only to find it completely out of use a few months later simply because their clients didn’t want to start using it.

Not only is Mango’s client portal user-friendly and easy to get started with, it comes with some of the most important features you’d expect from this kind of software:

  • Unlimited storage so that you can keep as much as you need in a client portal. You’ll be able to select your own yearly retention period so that as long as your service is active, you’ll have access to your data.
  • Mobile support so that you and your clients can access the portal anytime from any device. Even if you’re in a location without Wi-fi, you can still pull up your portal to get what you need or add files.
  • Self-service for clients. How many times have you been called or emailed by a client with a simple request that you wish they could have managed on their own? With Mango’s secure digital gateway, the wish can become a reality. Clients can check on invoices, service records, and other important details without getting you involved at all.

Bank-Level Security with Client Portal Software for File Sharing

The best portals will add convenience as well as security.

A client portal is convenient, but it doesn’t matter how easy it is to use if it can’t keep files safe. That’s why Mango’s client portal meets all legal requirements for secure document management – without adding an unnecessary extra hoop for your clients to jump through.

Mango’s client portal protects all of your files with 256-bit, bank-level encryption (the same type used by US security agencies) and our advanced firewalls.

Give the information they’re seeking on their own terms, even if it’s outside of business hours.
  • Instant Alerts - Mango’s real-time notifications not only let you know when clients completed an activity or uploaded a document, but also allow you to send gentle, automated reminders to your clients so you can get what you need sooner.
