The real argument
Each argument stands alone. Together, the maths is difficult to ignore. Set your numbers below and see what it's actually worth for your business.
Four global inputs — set once, used across all three columns
Argument 1
Every job creates admin. Install CRM cuts through it — structured capture, instant quotes, one-click invoices. The hours add up fast.
Your numbers
Admin rate (£18/hr) and owner rate (£40/hr) are set in the global inputs above.
Argument 2
Faster, more professional quoting wins more jobs. Install CRM lets you send a branded quote from your phone the same day as the survey — before the competition has even started theirs.
Adjust the assumptions
3 days is common when quoting is manual — it's not a criticism, it's just what happens.
Most installers we speak to are somewhere between 35% and 55%. This is your estimate.
Based on Dickon's own experience running Install CRM. Your improvement will vary.

Even half this improvement dwarfs the subscription cost many times over.
Argument 3
Return visits, rework, missed extras, and delayed invoicing don't show up on a spreadsheet — but they quietly drain the business every month.
This is not a criticism — these things happen to every installer, including Dickon. The question is just whether they happen once a month or once a week.
Your numbers
Includes ~2hrs travel + vehicle costs. Adjust for your geography.
At £40/hr owner rate = £30 per rework
Extras agreed on site verbally that never made it onto the invoice.
At 0.5/month that's £570 left on the table every year.
With 8 jobs at £2,800/job, a 8-day delay means ~£5,973 is sitting uninvoiced right now.
At £18/hr admin rate = £6 per chase
The verdict
Based on the sliders you set above. Adjust any of them — the numbers update instantly.
Time freed up — value per month Admin + owner PM time saved across all jobs | £528 |
More jobs won — additional profit per month From improved close rate via same-day quoting (at your margin) | £470 |
Costs eliminated per month Wasted visits, rework, and late invoicing cash drag | £325 |
| Total value created per month | £1,323 |
| Install CRM Lite plan | £79/month |

These are estimates based on your inputs. Real-world results vary — but every installer who uses Install CRM daily reports the same pattern: less admin, faster invoicing, more jobs managed with less effort.
