No.
You don't need a CRM.
Why
You're getting fewer than one inquiry every three days, all by phone, and you're the only person handling them. There is no pipeline to manage, no handoff to coordinate, no attribution to track. The only real risk is forgetting a callback or losing a name — and that's solved with a notebook and a missed-call habit, not software.
What you actually need
- A paper notebook or the Notes app on your phone (free) — one line per call: date, name, number, what they wanted, when to call back. That's it.
- Google Contacts (free) — save every caller's number with their name and a one-word tag ("quote", "repair", "wholesale"). Next time they ring, you know who it is before you pick up.
- A habit — the end-of-day callback sweep — before you lock up, scan today's entries and your phone's recent-calls list. Any missed call or "call back tomorrow" gets actioned or texted right then.
Do this today
Open your phone's Contacts app and, for every number in your recent-calls list from the last 7 days that isn't already saved, add it with a name and a one-word note in the company field. Then pin a blank notebook next to the till with today's date on page one. By tomorrow, no caller is anonymous and every inquiry has a physical home.
What to ignore
Anyone pitching you HubSpot Free, Zoho Bigin, Pipedrive, or "AI call tracking" at this volume is selling you furniture for a room you don't have. monday CRM and Freshsales ads will follow you around the internet — ignore them. You're a one-person shop with two inquiries a week; a £0 notebook beats a $20/mo dashboard every time.
What doing nothing costs you
With fewer than 10 calls a month, even one forgotten callback is a 10%+ hit to your inquiry flow — and in a brick-and-mortar shop, a missed caller often walks into a competitor instead. The compounding loss is reputational: people who weren't called back don't call twice.
When to revisit this
When you hire someone to cover the shop and both of you start answering the phone.
