This article will give you a clear understanding of the system and why it’s necessary. You will also get the top recommendations based on your agency workflow.

But before choosing the top CMS (Client Management Software), let’s check out the fundamentals first.

What is Client Management Software?

A client management software (CMS) is a platform that helps organize clients’ contact information, files, and track interactions to offer personalized services. From a single view, you can see – 

• Number of clients you’re currently working with
• How many projects are in progress, in review, and completed for a single client
• Invoices and subscription details of specific clients

The software basically handles all post-sales work. But it also addresses certain pre-sales operations, depending on the scenario, like for agencies.

You can organize client information, conversations, and follow-ups. Onboard clients with an intake form, and get the necessary files to start a project. Also, the platform helps to communicate within the platform regarding projects.

Agencies and businesses offering productized services commonly use client management software. The software organizes and links clients’ information and data to respective projects.

The purpose of customer management software is to give customers a more convenient experience. They feel listened to and become loyal clients. They even recommend your business to others.

What are the Benefits of Using Client Management Software?

Client management software automatically organizes client information and data and sends reminders when needed. That’s how organizations see a 34%-40% increase in productivity, according to Salesforce. Apart from these, getting a CMS for your business will get you the following benefits –

Organized Client Data

The software stores clients’ contact information and data in a database. This includes their name, email, phone number, company name, address, social media profiles, etc.

You don’t have to manually input their contact details and information. The system will send clients an intake form to get all details.

For each client, you will know – 

• Onboarding date
• Current plan/package
• Monthly/annual contract value
• Billing cycle
• Payment history
• What services they’re using 
• Past and ongoing projects/deliverables
• Conversations
• Files

Personalized Offerings

You will have all the details on clients and their activity and interaction data. Thus, you can offer personalized upselling and cross-selling services. Offering personalized services boosts related revenue by 39% according to Salesmate.

Let’s say you do SEO for a client. From the conversation, you will know the client has to update content on the website. 

You can offer the client a content writing service that is directly related to the service you offer him. When clients get personalized offerings, they feel more valued and stay longer.

Automating Repetitive Tasks

A client management platform automates client onboarding, keeps their records, and schedules meetings. It also handles invoices, sends follow-up emails, and more. 

The software takes care of most repeated admin tasks. Your team gets more time to work on billable projects.

Provides Insights

From a centralized dashboard view, you can see how many projects are ongoing and delivered for a specific time. You’ll also get a report on how much your team earned in revenue.

Enhances Collaboration 

Sales, project managers, and support teams all work from a centralized record rather than separate tools.

When a salesperson promises a client something, the delivery team sees it immediately. When support handles a complaint, sales know about it before their next check-in call. 

Clients don’t get five people asking them the same question.

Self-Service for Clients

Client management platforms allow clients to get self-service as per the platform’s capabilities. Let’s say one of your existing clients wants to know the update on an ongoing project.

Instead of emailing you, the client can log in to your portal, and can see what’s the current status of the project.

What are the Key Features of a Client Management Software?

Depending on the workflow, CRMs come with different features. The key here is to pick a software that offers features suitable for your specific workflow.

Contact and lead management is the prime function of CRMs. Several features come under it –

Centralized Client Database

All contact details, including email addresses, phone numbers, company information, social media profiles, and preferences, are in one place. You search for any required info, get it from the CRM and proceed further.

Some CRMs also have calendars and follow-up reminders. Clients can book appointments. Depending on the action taken, clients receive a notification or email.

All data and files of a particular client stay in a centralized spot. Both you and the client have access to invoices, project history, conversations, etc.

Communication Tracking

Your clients can communicate with internal team members. There’s an ongoing project on “Logo concept”. Clients can send messages within the task to make it relevant. Other team members also get the context, as messages will be within a particular task or project.

Workflow Automation

CMS automates productized service business and agency workflows. It significantly reduces the time for repeated tasks. You can automate a specific workflow based on trigger actions. For example, sending a welcome email with an onboarding guide when a client signs up.

You can also automate sending reminders and notifications for various reasons. And the follow-ups can be automated as well.

Client Portal

Modern client management systems offer client portals to give clients self-service of some sort. Around 67% of clients prefer checking project status through a self-service client portal, according to Motadata.

Clients can upload and access files, purchase products/services, and generate invoices. They can also check their project updates and communicate with the team from the client portal. Many CMS come with an integrated portal.

Reports and Analytics

Based on clients’ data, the client management system will get you with important insights and reports. 

There will be a dashboard as well to know specific information at a glance. You will see the revenue amount of the past month, the number of onboarded clients, etc.

You will see how much revenue you generated in a specific month or period. You will know their preferences based on clients’ activities and the products or services they purchased most.

Project Management

Client management software also comes with a project management tool. All projects and tasks related to clients stay organized in one place. You can organize projects as per status – pending, ongoing, complete, or in review.

You can go to projects and find the client’s name. Also, from the list of clients, you can see how many projects are ongoing for any particular client.

Collaboration Tools

Collaboration tools keep all team members aligned regarding client activities. Most client management software offers Slack integration to manage teamwork and task automation.

Integration

Third-party integration makes client management systems even more powerful. Integration helps if you need to import databases and insights from another platform.

Research from Forrester and Gartner shows that personalized recommendations powered by customer data drive up to 35% increase in sales.

Revenue increases up to 300% per order when using client history and behavior data to upsell.

How to Choose the Right Client Management Software 

As said earlier, you shouldn’t end up buying an overpriced and overkilled platform. You will end up paying for features you will never use. If your purpose is to keep your existing clients happy, here are key considerations you should keep in mind –

Use Case

Consider your workflow first. Do you only need to store clients’ contact details, information, and billing info? Or do you have to deal with deliverables?

A basic client management tool would be more than enough if all you need is to store contacts and billing info.

If your workflow also deals with projects and feedback, make sure you get a client management platform with a project management tool.

Having a client management tool like Agency Handy would be a plus for agencies selling multiple services. This CMS platform allows creating a catalog view of services. You can add multiple packages under each service with pricing tiers.

Some businesses need a scheduler for meetings and appointments. If you need this too, make sure your platform has it.

If you need an enterprise-centric client management solution, the tool should have dedicated sales, marketing, and analytical tools. These are expensive and only suitable for larger businesses and enterprises.

Must-Have Features

Client management software comes with some basic features like – 

• Contact management
• Document sharing
• Communication
• Reports
• Sending emails and follow-ups, and
• Activity logs

These features are non-negotiable to develop an efficient client management system. 

But modern CMS tools also come with some advanced features, including –

• Automation
• Client onboarding
• Client portal
• Project management tool
• File feedback tool
• Time tracker
• Invoice and billing
• AI

These features are optional based on your workflow and requirements. If you want to do some heavy automation stuff, your platform should come with an advanced automation system. 

Similarly, a project management tool is necessary for agencies doing client projects. Design and creative agencies will benefit from the file feedback tool.

Scalability

You can add your team members to the client management platform to serve clients. If your business needs to grant 50 employees access to your platform, paying for a 10-user license isn’t worth it.

Similarly, if you work as a freelancer or own a small team, don’t overpay for enterprise software.

User Experience

The client management software has to be simple and easy to use for your internal members as well as clients. Commonly used functions should be easy to navigate. 

After you shortlist tools, be sure to use the trial version to see how the interface and overall user experience are.

Cost

Client management tools with entry-level packages cost $10-$30/user/month.

Mid-tier plans cost $40-$150/user/month. And top-tier business and enterprise-focused plans anywhere between $150-$1500/month. 

If the pricing plan indicates per-user cost/month, consider how many users will use the tool.

Software Reviews

Even before you use a customer management tool, you can get some idea about the software by going through reviews on G2, Capterra, and Reddit as well. 

Trial

These software offer a minimum 7-day free trial. You should try all your shortlisted tools one by one to finally decide which one to settle down with.
