Every business has a Dave. Every business is one holiday away from finding out how much of it lives in his contacts app.
Ask a lot of small trade businesses where their customer history lives, and the honest answer involves someone's mobile phone, a WhatsApp thread, and a slightly uneasy laugh. It works, mostly, right up until Dave's on a job with no signal and a customer calls asking what was agreed three visits ago.
What a real customer record actually holds
Not just a name and number - every quote, job, invoice, note, and photo tied to that customer, visible to whoever picks up the phone, not just the person who happened to do the original job. That's the difference between "a contact" and "a customer record."
Why this matters more as a business grows
At two people, tribal memory mostly works. At six or ten, it starts causing genuine problems - repeated questions, contradicted promises, and a slow erosion of the trust that repeat customers are built on. A shared customer CRM isn't about adding bureaucracy, it's about making sure anyone on the team can pick up where the last conversation left off, without a phone call to Dave.
The verdict
Dave's memory is genuinely impressive. It's also not a system, and it definitely shouldn't be the only place your business's history lives.
