Ownership cost planner

Compare the total cost behind two software choices.

Enter the prices and terms you received from each provider. The planner includes seats, base fees, add-ons and one-time setup so a headline monthly price is not mistaken for total cost.

Procurement checkpoint

Validate Microsoft Teams and Slack beyond the feature list.

Use this after reading the comparison and entering your own prices in the total-cost planner. It helps organize evidence for a technical and commercial review; it does not rank a provider, verify a claim or replace your procurement process.

I wrote the workflow, users, integrations and measurable outcome this purchase must support.I confirmed the edition, plan limits, seats, permissions and features included in each option.I documented migration effort, import limits, data export format and an exit path before starting a trial.I reviewed security, privacy, retention, subprocessors and any compliance material relevant to our data.I checked uptime commitments, support channels, response targets and escalation terms for our plan.I tested the critical workflow with representative data instead of relying only on a feature list or demo.I compared billing frequency, taxes, minimum seats, add-ons, annual increases, renewal and cancellation terms.I recorded the decision owner, pilot acceptance criteria, implementation tasks and training responsibilities.I saved the proposal and contract version that the team actually reviewed, including the quote expiry date.
