Sometimes the honest answer is no. A few tests.
You probably do not need a CRM yet
If you handle fewer than about ten inquiries a month, you are the only person who talks to customers, and nothing has fallen through the cracks that you know of. A well-kept spreadsheet is fine at that size, and I will tell you so.
You probably do need one
If any of these is true: you have lost a job because nobody followed up, more than one person answers the phone, you cannot say how many inquiries you got last month, quotes go out and disappear, or you are spending money on advertising without knowing which ads produce work.
That last one comes up constantly. People spend on Google Ads for a year with no way to connect a click to a completed job. The ads are fine. There is nowhere to record what happened.
Why I do not sell you a platform
Most CRM consultants are partners of one system, and their recommendation is that system.
I implement whatever fits. Which one depends on things that have little to do with software: how many people will touch it, whether you need job scheduling or only contact tracking, whether your team is on phones all day, what you already pay for, and how much complexity you will tolerate before quietly going back to the notebook.
That last factor decides more implementations than any feature list. The most powerful CRM on the market is worthless if your crew will not open it. I have seen an expensive system abandoned in six weeks and a cheap one still running four years later.
