Glasscubes makes client communication simple, secure, and seamless.

The most frustrating things about operating an accounting business aren’t about accounting at all—they are the administrative tasks (such as following up with clients and chasing down documents) that waste time and invoke boredom.

You can say goodbye to those mindless tasks with Glasscubes.

Glasscubes makes everything about client communication easy. You can:

• Ditch the endless emails. Glasscubes will email clients for you on a schedule you set.
• Improve clients’ response times. Clients don’t even have to log in to their unique file request portal unless you require it, so they’re more likely to use it.
• See all conversations in context. Chat about individual files with clients within the file request portal. You’ll always have that conversation to refer back to in the future.

“Really enjoying using Glasscubes as an information-gathering tool. We are a firm of accountants, and this clever but simple software is saving us time and helping us automate [while maintaining a] personal touch and branding.”
