Rubrol Compute Arbitrage

Rubrol compiles documents in under 6ms with 96% less compute than Headless Chrome, so the agency margin lives in the gap between what the client pays per document and what the sidecar actually costs to run. Price the retainer against the client's current Chrome or Puppeteer bill, not against Rubrol's licence. A fintech client generating 200,000 invoices a month pays roughly $400 for Rubrol Enterprise, which adds Factur-X and PDF/A-3b plus the Schematron validator for XRechnung 3.0, then the agency charges a document infrastructure retainer that reflects the compute removed from the client's cloud account. The Rubrol Invoice Launch Kit at $4,500 and 32h setup is the entry point; recurring margin comes from operating the pipeline, not from the install. Below roughly 50,000 documents a month the arbitrage is too thin to defend a retainer.
