A CRM total ownership cost worksheet should make competing proposals comparable over the same period. Subscription or build fees are only part of the picture. Your team also spends time defining workflows, preparing data, learning the system and maintaining connections. The useful question is what resources each option needs to deliver the same agreed operating scope.
Fix the comparison boundary first
Choose an evaluation period, such as three years, and describe the user roles, integrations and workflows included. Use the same assumptions for every option. Comparing a basic sales subscription with a custom system that includes a customer portal says little unless the difference in scope is made explicit.
Record the expected number of users by role and year. Distinguish people who edit records from occasional viewers if the supplier's proposal treats them differently. Mark uncertain assumptions, such as adding a second team, so they can be tested as scenarios. Do not bury possible growth inside an unexplained contingency figure.
Build separate cash and effort views
The cash view includes amounts the business expects to pay to suppliers. The effort view records internal hours by role. You can value those hours using your own planning rates, but keep that result separate from cash expenditure. Staff time has an opportunity cost even when it does not create a new invoice.
Do not count the same work twice. If a fixed implementation quote includes data mapping, exclude those supplier hours from additional development allowances. Internal review of the mapping is a different task and may still belong in the effort view. Give every line an owner who can explain what is included.
Use a worksheet with traceable inputs
For each line, record the item, quantity, unit, rate or quoted amount, timing, source and confidence level. Use a supplier proposal, an internal estimate or a measured rehearsal as the source. A blank amount means unknown, not zero. Keep unknown items visible until someone resolves them or explicitly excludes the work.
- Initial work: discovery, configuration or build, data preparation, testing and training.
- Recurring services: licences, hosting, support and integration services where applicable.
- Internal operation: administration, user onboarding, access reviews and exception handling.
- Change: new reports, revised workflows, connector updates and additional data sources.
- Exit: exports, documentation, transition support and replacement-system preparation.
Specify whether amounts are presented on the same tax basis, without assuming a particular treatment. Ask your finance team to choose the basis for comparison. Keep one-off, annual and monthly charges separate so a monthly amount is not accidentally added as though it covered a full year.
Worked hypothetical example: comparing resource requirements
Consider two fictional proposals for the same three-year scope. Use abstract cost units rather than market prices. Option A has an initial external cost of 90 units and recurring external costs of 30 units per year. Its three-year external total is 90 plus three times 30, or 180 units.
Option B starts at 120 units and recurs at 18 units per year, giving 174 units. That six-unit difference is too small to settle the decision without reviewing exclusions. Suppose A also needs 80 internal setup hours and four administration hours per month. Its internal total is 80 plus 36 times four, or 224 hours.
If B needs 140 setup hours and two administration hours per month, its internal total is 212 hours. Present the cash units and hours side by side. Only combine them after applying the organisation's chosen internal valuation. These invented inputs demonstrate arithmetic; they are not CRM prices, supplier quotations or expected savings.
Test the assumptions that could reverse the decision
Identify the largest uncertain drivers rather than changing every line randomly. Useful scenarios include a larger user group, an additional integration, more frequent workflow changes or a longer period of parallel operation. Ask suppliers how those changes affect their proposals and record the answer alongside the relevant line.
For internal effort, use a rehearsal where possible. Time a representative data-cleaning batch or a support task, then state the assumptions behind extrapolating it. A sample full of clean records will underestimate the work of resolving ambiguous ones. Show a range when the evidence supports a range, and avoid disguising uncertainty with precise decimals.
Keep benefits separate from the cost calculation
Potential benefits deserve their own worksheet. State the task expected to improve, the present baseline, the proposed change and how it will be measured. Time saved does not automatically become cash saved: the team may use that capacity for better follow-up or absorb more work without expanding.
Do not subtract every hoped-for benefit from cost to produce an impressive net figure. Test whether benefits overlap. Faster enquiry capture and less duplicate entry may describe the same saved minutes. Give each benefit an owner and a later review date so the business can compare the original assumption with actual use.
Use the worksheet as a decision record
Before choosing, review unresolved costs, capacity constraints and dependencies with the people responsible for delivery. A lower total may still be unsuitable if it requires internal skills or time the business cannot provide. Record why the selected option is affordable and operable, including what would trigger a budget review.
Carry the accepted assumptions into the CRM project handover so ongoing costs have owners.
