Why

10-50 phone inquiries a month across 2-3 people is roughly one call each per day. That's a notebook problem, not a pipeline problem. Trading deals live and die on "did you call him back on Tuesday like you said you would" — and right now nothing is forcing that question on you. A CRM would just become a tab nobody opens between site visits.

What you actually need

1. Google Sheets (free) — one tab "Clients 2026" with columns: Date / Client / Phone / What they want / Last contact / Next call date / Owner. One row per inquiry, one owner per row.
2. Google Contacts on each phone (free) — every inbound caller gets saved with a tag like "LEAD-" prefix so you can see at a glance who's a live prospect when they ring back.
3. A habit — the end-of-day 10-minute call — every evening, the 2-3 of you spend 10 minutes on a group call updating the sheet with today's visits and tomorrow's call list. Non-negotiable.

Do this today

Open Google Sheets, create "Clients 2026" with the seven columns above, share edit access with the other 2 people on your team via the Share button (top right). Tonight at 7pm, all of you sit down and fill in every client conversation from the last 7 days from memory. By tomorrow morning you'll have your first real "who do I need to call back" list instead of relying on what you remember from the road.

What to ignore

Skip Salesforce, HubSpot Sales Hub, Pipedrive, and Zoho — any rep telling a 3-person trading team they need a $20-50/seat/mo CRM is selling you software you'll abandon in six weeks because you're in a client's office, not at a desk. Mobile CRM apps sound great until you realise you won't open them between meetings either.

What doing nothing costs you

A conservative 20% slippage on 10-50 phone inquiries/month = 2-10 forgotten callbacks every month. In trading, where the second-best quote loses, that's deals your competitor closes because he called back on Tuesday and you didn't.

When to revisit this

When the sheet has more than 300 rows, or when two of you call the same client on the same day without realising.
