Client onboarding should be swift and effortless, but it’s rarely ever like that. In reality, most service-oriented businesses find themselves grappling with everything from scattered communication channels to information gathering hurdles.

Jodi Porteous of Northwest Accountancy sums it up nicely:

We were sending clients Excel spreadsheets, and they’d send back half the information or no information at all. The accountants were getting frustrated, and the clients were getting annoyed because they were like, ‘I don’t know what you want me to do here.’

These pain points can slow down business growth, but you can solve them by using client onboarding tools.

With the right platforms at your disposal, it’s easier to send proposals, collect payments, gather information, and much more, all within a centralized and user-friendly ecosystem. In this post, we’ll show you some of the best client onboarding software solutions.

Client onboarding: Definition and typical stages

Client onboarding sets the stage for a successful business relationship. It involves a series of stages aimed at smoothly transitioning a client from the initial contact to becoming an active participant in a project or service.

1. Sending proposals and signing contracts

The process begins with the submission of proposals and the subsequent signing of contracts. We also know it as an engagement letter, a document that establishes a formal agreement between the client and the service provider. It outlines the scope of work, project timelines, deliverables, and financial arrangements.

2. Gathering information and documents

Once you sign the contract, the onboarding process proceeds to gathering essential information and documents from your client. This usually involves things like intake forms, surveys, or questionnaires to gather specific details about the client's requirements.

3. A well-structured welcome package

This package typically includes a welcome letter, an overview of the onboarding process, key points of contact, and any necessary instructions or access details for project management tools or communication platforms.

4. Project launch

The project launch stage marks the transition from preparation to active implementation. At this stage, you’ll have regular check-ins and progress updates to maintain open lines of communication.

5. Feedback and evaluations

As the project unfolds, you’ll need to engage with clients regularly to gather their thoughts, remarks, or suggestions. That way, you can identify areas for improvement and make necessary adjustments.

Client onboarding platforms: Our top picks

There are hundreds of tools that can simplify business procedures and ensure client success, but we know you don’t have enough time to test them all. Here are some of our favorite platforms for improving the onboarding experience.

Information gathering tools

1. Content Snare

Client onboarding requires a lot of documentation and data collection. If you do it in a traditional way, you’ll get stuck in an endless loop of back-and-forth emails. But if you use Content Snare, you’ll make the process much easier for your clients (and yourself).

2. ClustDoc

ClustDoc, like Gatheroo, is another data collection tool that comes with powerful features. However, this tool lacks that much-needed autosave function that enables users to pick up where they left off, which is particularly inconvenient if your clients need to fill out long online forms.

3. Google Forms

Many solopreneurs and small businesses search for a free form builder, which is why Google Forms is such a popular option. The benefit of this platform is that it seamlessly integrates with other popular Google services. On the downside, Google Forms can’t compare with paid tools in terms of customization, autosave, or conversations.

1. Proposify
