No.
You don't need a CRM.
What's really going on
You get fewer than 10 inquiries a month across email, a web form, and LinkedIn. That's not a pipeline problem — that's a memory problem. Leads slip because nobody owns the reply, not because your tool is wrong. With three channels and three people, the real risk is two of you emailing the same buyer, or nobody emailing them at all.
What to do instead
- Google Sheets (free) — one tab: date, company, channel, contact, what they asked for, who owns it, next step, next-step date. That's your CRM.
- Zapier (free tier) — two zaps: web form → new row in the sheet, and LinkedIn message saved → new row. Now nothing lands without showing up in one place.
- Habit — 10-minute Monday standup, all three of you, walk the sheet top to bottom. Any row with no next step gets one or gets closed.
First action, today: open a new Sheet, paste those eight columns, drop in every live inquiry from the last 30 days, and assign an owner to each row before lunch.
What you're being oversold
Someone will tell you HubSpot Free or Pipedrive will "professionalize" your sales. At your volume, HubSpot's free tier is a parking lot you'll never fill, and Pipedrive at ~$14/user/mo is paying for empty pipeline stages. Both will quietly push you toward paid tiers you have no use for. Doing nothing costs you the one or two leads a month that fall between the three of you — on construction accessories and workwear, those reorders compound, but you don't need software to stop the leak. You need a shared sheet and a Monday huddle.
When to revisit this
When you cross 30 new inquiries a month, or you hire a fourth person who isn't sitting in the same room.
The part worth getting right
Here's the call: are those <10 leads mostly small one-off web orders, or are they mostly distributors and contractors who reorder for years? If it's one-off web buyers, a sheet is the whole answer and you should spend your money on getting more traffic. If even two or three of them are repeat-buying contractors, you need a second tab — accounts, not leads — tracking last order, reorder cadence, and who they buy for. Get that fork wrong and in a year you'll either be paying for a CRM you don't fill, or you'll have lost a $40k/year contractor because nobody remembered to call in March.
