As your business grows, it's important to consider having a CRM (Customer Relationship Manager) to track your leads and sales. I can't tell you how many potential jobs I lost early on in my career just because I forgot to follow up and keep up with people I spoke with. It doesn't matter if you're handling just a few contacts a month or have a salesperson working for you, you need a workflow that helps you grow your business.
There are a TON of CRM tools out there that are geared towards everything from photographers to massive corporations, but the basic functions of all CRMs are the same. A CRM should allow you to record contact information people and connected organizations, track communications (phone calls, emails, etc), provide reports on growth and activities, and schedule followups.
I have two creative businesses and have separate CRM's that are geared towards the specific needs for the businesses. For my wedding videography business, I use Honeybook, which does everything I listed above, but is more focused on date-based client work, and handles proposals, contracts, invoicing and payments internally. For my brand-focused creative business, I use Pipedrive which is a standard CRM, but much more powerful for handling lead tracking in bulk.
I'm a big believer in creating processes to make running my businesses easier. With that, I've tested a TON of CRMs in the past few years. The last thing that a CRM should do is consume a bunch of time to maintain. It should take some work to get set up, but after a week or two, it should be running mostly automated and be integrated with your workflow. Some CRM's have a ton of enticing features, but often those features become something you have to take a lot of time to keep updated, otherwise, you won't have a good pulse on your business.
