Let's be real, document collection sucks.

Document collection is about as exciting as watching paint dry. You’re constantly sending reminders (after reminders). When you do get responses (often in drips) at times the document or content is either in the wrong format or way off base from what you requested…sounds familiar?

It's time-consuming

Collecting data, documents and signatures from clients is time-consuming. Free up your time, so you can focus on value-added work (stuff clients actually pay for).

Client experience suffers

The traditional PDF forms and back-and-forth email threads no longer cut the mustard. Your clients deserve a modern digital experience to provide you with information.


Version control is messy

Document collection via endless streams of emails is a version control nightmare. You run the risk of actioning services based on information buried within superseded emails.

Use rich content for better engagement

Don’t overload your clients with text-heavy instructions buried in static docs. A better approach is to incorporate a mix of dynamic text with rich content such as images and videos.


Always be informed of progress

Get notified immediately when a document collection form is ready for your review. Get daily notifications of the completion rate for all in-progress forms.
