5 Best Investor Onboarding & Subscription E-sign Software

Don’t Get Caught Trying To Raise Capital Without An Investor Onboarding Software

As the entire financial world goes digital, it’s no surprise that the private investment market is finally undergoing a digital transformation.

Conventional processes for onboarding investors for private investment are plagued with time-consuming, error-prone, and tedious manual activities such as emailing documents, gathering information, running compliance checks, and collecting signed subscriptions. 

As a result, many capital raisers are missing out on opportunities to work with wealth advisors, family offices, high-net-worth individuals, and mass affluent investors since they can’t cope with the volume and complexity of working with them. 

Even worse, given the numerous and demanding tasks for investors, investors are more likely to put them off or get distracted by other priorities, resulting in delays or even dropouts. Meanwhile, the capital raisers don’t even know what happened. 

The good news is that modern investor onboarding software solves all these issues and offers outstanding returns to your capital-raising efforts.

What Is Investor Onboarding & Subscription E-sign Software?

Investor onboarding software is a convenient way to onboard investors with a series of guided digital steps. Because all the supporting features are included to support the investor journey, you can create any onboarding paths as you see fit.

  • Create a custom onboarding journey of various steps
  • Create custom questionnaires to collect investor information
  • Triage investors based on collected information 
  • Run standard or custom compliance checks. For example:some textsome text
    • KYC
    • AML
    • KYB
    • Accreditation
    • Suitability
  • E-sign pre-filled subscription documents
  • Track onboarding progress and automatically follow up
  • Process online payment or issue capital call   

When you are ready to onboard investors, simply email them secured links to start onboarding.

Investor onboarding software offers many benefits for private capital professionals:

  • Access Untapped Capital Base: With increased automation to handle high volume and complex onboarding flows, you can access previously untapped capital bases such as wealth advisors, family offices, and high-net-worth and mass-affluent individuals.     
  • Raise Capital Faster & Decrease Dropout Risk: By removing manual errors and friction, we have seen an average 98% reduction in investor dropouts and a 500% increase in processing speed.
  • Cut Down Manual Overhead: By using automation, 95% of manual errors and 80% of manual overhead are eliminated. 
  • All-in-one: To support various onboarding processes, onboarding software usually includes 5 - 7 tools, such as an E-signature Builder, Journey Builder, Form Builder, Compliance Checks, Progress Tracking, and Follow-up Automation.   
  • Cost-Effective: Compared to cobbling different tools, onboarding software saves lots of money and time.
  • Professional Look: A sleek and organized portal is often seen as a sign of the capital raisers’ credibility and professionalism. 
  • Easy To Upgrade And Integrate: Investor Onboarding software can be used alone or along with other tools such as CRM, data room, and reporting via upgrade or integration.

Once you’ve decided that you want to capitalize on the benefits investor onboarding software offers, you’ll need to decide which software to use.

How To Choose the Best Onboarding Software For Your Needs? 

Although onboarding software has been around for a few years now, solution offerings can vary widely. Therefore, it’s important to identify the one most suitable for your needs. Here are a few key factors to consider.

  • What features do you need?

Depending on your use case and current workflow, you might need an end-to-end platform including 10+ features to revamp your entire operational flow or you just need a standalone platform with 2 - 4 features to handle one specific problem. Caveat: Be mindful that your immediate needs (e.g. launch a fund in 3 months) could differ from your long-term growth needs (e.g. penetrate wealth advisor markets). Therefore, in addition to having all the features you need today,  you should give preference to software with easy add-on features you might need in the future.

  • How much customizability do you need?

While low-cost vendors usually provide less customizability to save cost, you should consider paying a premium for software with high self-customizability in key areas such as onboarding flow creation, e-sign template creation, reporting, investment presentation, and marketing automation. For one, it’s much more costly to fit your workflow into software. Even if the vendor does free customization to fit your workflow initially, it’s likely your workflow will evolve and update over time, making it increasingly more difficult and expensive to update.

  • Does the software support your use cases?

Depending on your investor types and objectives, your onboarding journeys need to vary. For instance, wealth managers need the ability to manage their investor sub-accounts separately and view data in the aggregate; investors with multiple account types (e.g. individual, joint, trust) need the ability to quickly switch between accounts and view accounts separately as well as in aggregate; institutional investors need multiple users under one account with different privileges. 

  • Is the software suitable for your budget?

The cost can vary greatly depending on the factors mentioned above. The decision comes down to the value you can realize. In general, the more investors you need to work with,  the more complex your workflows & documents are, the more parties involved in collaboration, the more value you will realize from well-designed onboarding software. 

While several vendors provide Investor Onboarding Solutions, five stand out as either superior or suitable. We therefore ranked the top 5 in the order below, with WealthBlock standing out as the clear top provider based on features, functionality, flexibility, security, and affordability.
