GTM tool cost modeling — per-seat licensing, usage-based fees, cloud infra, enrichment credits, annual vs monthly contracts, and fully-loaded RevOps stack TCO. Use when budgeting GTM tools, calculating cost per rep, vendor renewal negotiation, or stack ROI. Triggers on: "GTM tool budget", "tool cost calculation", "SaaS stack TCO", "licensing costs", "per seat cost", "enrichment credits cost", "cloud costs GTM", "vendor spend model".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GTM Tool Cost Model ## Overview GTM tool spend hides in **per-seat**, **credit**, **platform**, and **cloud** lines — and renewals jump 15–30% year two if nobody models TCO. The mistake: approving tools from demos without a **fully-loaded cost per rep** or **cost per $1M ARR**. This skill builds finance-ready tool budgets: licensing, usage, implementation, and infra — tied to ARR stage and headcount. Stack design → `revops-tech-stack`. Contract terms → `vendor-contracts`. P&L integration → `financial-modeling`. **Operational spend** (Ramp, approvals, vendor roster) → `gtm-spend-management`. ## When to Use - "Calculate our GTM tool costs" - "Budget for CRM + enrichment + sequencer" - "Cost per SDR/AE for tools" - "Model Clay credits vs headcount" - "Renewal negotiation data" - "TCO for Salesforce vs HubSpot" ## Authoritative Foundations - **Ben Murray (SaaS CFO).** Model vendor spend as % of ARR and per departmental head. - **David Skok.** Tool spend should ladder into CAC — if stack CAC > benchmark, fix before adding tools. - **Scott Brinker.** Consolidation reduces redundant MarTech tax. - **Jason Lemkin.** Typical GTM spend bands by ARR stage (directional). …

How to install
mdr add leadmagic/gtm-skills/gtm-tool-cost-model@sha256:4ed28052e9fcc10fThe line at the top of this page pins the label v1.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
