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 suffice. 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 You run the risk of taking action on services based on information buried within outdated emails.

Let our document collection software do the chasing for you

The good news is, you no longer have to put up with the stress of constantly chasing clients for information and documents. Let Portalstack document collection software do the heavy lifting for you. What’s more, your clients will thank you.
