How to calculate the business case for a custom CRM

A worksheet approach: price the workarounds, the leakage, and the reporting you can't produce — then compare honestly.

The cost of a CRM project is visible on a proposal. The cost of not doing one is scattered across timesheets, lost deals, and meetings about spreadsheets — which is why the status quo usually wins by default. A credible business case makes the invisible side countable.

Count the current costs

  • Re-entry time: hours per week your team spends copying data between tools, priced at loaded cost.
  • Response leakage: leads that never got a first touch, or got one too late to matter. Even a conservative estimate is usually sobering.
  • Follow-up decay: quotes and estimates that died from silence rather than a 'no.'
  • Reporting labor: hours spent assembling numbers by hand — and decisions delayed while waiting for them.
  • Tool sprawl: overlapping subscriptions kept alive because each holds a fragment of the customer.

Then be honest about the other side

A build has one-time and ongoing costs, an adoption risk you must plan for, and a payback period that depends on your volumes — not on a vendor's slide. Run the numbers with your own data, stress-test the assumptions, and let the comparison decide. If the workaround costs are small, keep the platform you have; the honest answer is sometimes 'configure, don't build.'
