CRM for a small firm: start with a sheet, grow only when it hurts

What a CRM is, in plain words

CRM stands for customer relationship management. Forget the name. It answers three questions: who asked, what did we promise, and what happens next?

A plumber takes a call about a leaking tap on Monday, promises a quote by Wednesday and forgets, because a pipe burst on Tuesday. That is the problem a CRM solves. Not a fancy dashboard. A list where Wednesday's quote is written down next to the name.

Every job moves through the same few stages: enquiry, quote, won, after-service. A CRM shows each customer on that line, so you see who is stuck where.

Three signs you need one

1. Enquiries get lost. A message in one inbox, a call in your pocket, a form in an email you did not open.
2. Follow-ups are forgotten. The quote went out, and nobody asked a week later.
3. More than one person answers. The moment two people talk to customers, each knows only half of the story.

If none of these happens, you do not need a tool yet. A notebook is fine.

Why bother with follow-ups at all? Amy Gallo wrote in Harvard Business Review (29 October 2014) that winning a new customer can cost "anywhere from five to 25 times" more than keeping an existing one, depending on study and industry. The article names no source for that range. It also cites Frederick Reichheld of Bain, who found that 5 % more retention raises profits by 25 % to 95 %. That research is old and often quoted, so treat it as a direction, not a forecast for your firm. What we take from it: a customer you already have is likely the cheapest enquiry you will get, and a CRM reminds you to ask.

How common are CRMs in small firms

Eurostat counts firms using CRM software. For 2021, among firms with 10 or more persons employed, it was 21.9 % in Slovakia, 18.1 % in Czechia and 34.8 % in the EU. Only 2021 is available, and firms under 10 staff are not included, so these figures say nothing about a barber or a two-man heating firm. They only show that most mid-sized firms in both countries did not use CRM software then.

Three steps, in order

Step 1: a spreadsheet or notes app. It costs nothing, and you know it already. For a firm taking a few enquiries a day, this is enough.

Step 2: a no-cost tool. When the sheet has too many rows, or two people edit it and trip over each other. Prices checked on 4 November 2026: HubSpot has a CRM at no cost for up to 2 users and 1 000 contacts, with no time limit; its Starter plan is shown from $7 per seat a month on yearly billing, or $10 monthly, for new customers for a limited time. Zoho CRM has a no-cost edition for up to 3 users. We could not read its paid prices on the page, so we give none. Plans at no cost have limits, and plans change. Check before you commit.

Step 3: a CRM that comes with your website. If your website already stores form enquiries in a list with a status, you skip the copying. Ask your web builder whether it includes one and whether you can export the data. We built an invented demo of such a screen, a made-up firm, at CRM demo. It shows the idea, not real customers.

A day with the sheet: a heating firm

Monday, 8:10: a form arrives, "boiler service, flat in Petržalka". You add a row: source = website form, stage = enquiry, next step = call, next step date = today. At 8:20 you call, agree a visit and move the stage to quote. Thursday you send the quote and set the next step date for the following Wednesday. On Wednesday the row is at the top of the sort, so you ring. The customer says yes. Stage: won. After the service, you set a date three months out to ask how the boiler runs.

Nothing here needs software. It needs the row to exist, and the date to be read.

A minimal sheet: 10 columns

One row per enquiry. No more than this to start:

1. Date the enquiry arrived
2. Name
3. Phone or email
4. Source (form, call, message, referral)
5. What they want in one line
6. Stage (enquiry, quote, won, after-service, lost)
7. Quote amount
8. Next step
9. Next step date
10. Who owns it

Sort by "next step date" every morning. Anything in the past is a promise you have not kept.

How the website feeds it

The contact form should create a row by itself: name, contact, message, source = website form and the date. A contact form usually sends an email notice. Paste it into the sheet, or set up a rule in the tool you choose. Calls and messages from Instagram or WhatsApp you log by hand, in 20 seconds, right after the call. The habit matters more than the tool: no row, no enquiry.

After a job, move the row to "after-service" and set a date to ask how it went. That reminder is where the HBR argument pays off.

Where to start

Open a sheet today, paste in the last month of enquiries from your inbox and phone, and mark the ones nobody followed up. If that list is not empty, you have your answer on whether you need a CRM. If you want the form on your website to feed it cleanly, tell us through the contact form.
