Stop the craziness of using email for new vendor onboarding

Onboarding is one of the most important processes in establishing a new vendor relationship. But collecting information to onboard vendors can often be a real pain (for both you and your vendors).

It's time-consuming

Collecting information to onboard new vendors can be time-consuming, which inevitably leads to delays in the collaboration phase.

Vendor experience suffers

The traditional PDF forms and back-and-forth email threads no longer cut it. Your vendors need a modern onboarding experience.

Version control is messy

Without a centralized system, it’s difficult to track document versions during onboarding. Multiple versions can lead to confusion and errors.

Onboard new vendors up to 80% faster with our vendor onboarding software

The good news is, you no longer have to participate in playing email ping-ponging to collect all the required information to onboard new vendors. Let our vendor onboarding software do the heavy lifting for you. What’s more, your vendors will thank you.

Frequently asked questions

Is there a monthly 'request' limit?

No. Unlike other onboarding software, Portalstack does not impose a limit on monthly ‘active requests’ (i.e. the number of monthly onboarding forms you can send to vendors requesting information).

What information can be collected?

Essentially anything that your vendors can input or upload can be collected – for example, vendor data, business information, content, documents, images, files, etc.

Is there a charge for vendor access?

No. You can add as many vendors as you want. We only charge you for your internal users under your subscription.

How secure is the data?

We take data security seriously. Our platform is hosted on Amazon Web Services sitting behind their bank-grade infrastructure with 256-bit encryption. We’ve designed Portalstack with a security first architecture. You can find out more by reading our Security Policy.
