Every CRM vendor will tell you that you need a CRM. We sell CRM work, so treat what follows accordingly — but our honest position is that a spreadsheet is fine for longer than most people selling software will admit.
Here's how to tell when it stops being fine.
Signal 1: More than one person edits it
A spreadsheet is a single-writer tool wearing a multi-writer costume. The moment
two salespeople work in the same sheet, you get overwritten rows, three versions
named final, and a WhatsApp message that begins "did anyone delete…".
If exactly one person maintains your customer list, a spreadsheet is genuinely fine. If it's three, you already have a problem — you just haven't priced it yet.
Signal 2: You can't answer "what happened with this customer?"
A spreadsheet stores state: name, phone, status. It does not naturally store history: who called, when, what was said, what was promised.
When a customer rings and asks about the discount someone mentioned three weeks ago, and nobody can find out whether that conversation happened — that's the limit of the format, not of the person maintaining it.
Signal 3: Leads arrive in four places
Website form. Facebook lead ad. WhatsApp. Someone's personal phone.
Each one needs a human to notice it and copy it across. Humans are bad at this, especially on busy days — which are exactly the days you get the most leads.
This is usually the point where the real cost shows up. Not the software: the leads that went cold because nobody was sure whose job it was to follow up.
Signal 4: You can't tell what's working
Ask: how many enquiries came in last month, how many became customers, and where did the ones that converted come from?
If answering that means an evening with the spreadsheet, you're making budget decisions on a hunch. That's expensive in a quiet way — you keep paying for the channel that feels productive rather than the one that is.
Signal 5: Onboarding takes weeks
When a new salesperson has to learn which columns matter and what the colour coding means from whoever set it up, your process lives in one person's head. That is a real business risk on the day that person leaves.
If you've got three or more of these
Buy, don't build. HubSpot's free tier or Zoho covers what most growing businesses need. Configuring one properly costs a fraction of building one.
Custom is worth it when your process genuinely doesn't fit an existing tool — unusual pipelines, or deep integration with systems you already run. That's a real situation, but it's rarer than the people selling custom builds suggest.
The thing that actually determines success isn't which tool you pick. It's whether your team uses it. A CRM nobody updates is worse than the spreadsheet it replaced, because now the data is wrong and it's in two places.
So budget for training and for connecting your lead sources automatically. If adding a lead is manual work, it won't happen on a busy day — and busy days are the ones that matter.
The honest summary
- One person, under 200 customers, one lead source: stay on the spreadsheet.
- Multiple people, multiple lead sources, history that matters: move.
- Somewhere in between: move when the admin annoys you more than the setup would.
If you want a second opinion on which side you're on, our CRM service page covers how we approach it — and we'll tell you to stay on the spreadsheet if that's the right answer.
