Most businesses talk about CRM size.
“How many contacts are in it?”
That number feels comforting.
It shouldn’t.
Because what really matters is
how much water is still in the bucket.
The leak nobody tracks
CRM data decays constantly.
- People change roles
- People move companies
- Email addresses stop working
- Some contacts leave the workforce altogether
Industry studies consistently show 20–30% of B2B contact data becomes inaccurate every 12 months.
So even if your CRM never shrinks,
its usefulness does.
Two mindsets, same blind spot
We usually see one of two positions:
- “Our CRM is huge.”
- “Our CRM is clean.”
Both often ignore the same question:
How is it being refilled?
A CRM is not an asset you build once.
It’s a system that leaks daily.
Refill is not a scramble
Every inbound lead is more than a single opportunity.
If Person X from Company Y in Industry Z enquires:
- How many other companies look like Y?
- How many similar roles exist across Z?
- When are they added?
- By what method?
Inbound should expand the CRM, not just feed this week’s pipeline.
You can only hit a list so many times
When engagement drops:
- Open rates fall
- Replies dry up
- Campaigns stall
That isn’t bad timing.
That’s the bucket emptying.
Repeated outreach without refill accelerates the leak.
At Monofix we work on one assumption:
Roughly 1% of your CRM will engage with you at any given time.
That forces clarity.
Example
- Revenue target: £5m new business
- Average deal value: £5k
- Deals required: 1,000
- At 1% engagement → 100,000 relevant contacts needed
No hype.
Just maths.
The question that matters
What is your CRM refill process?
- How often does it happen?
- From where?
- Using what logic?
