SIXT RENT A CAR LIMITED has completed the GBP-14 Diagnostic and is certified as a Customer of Choice. Unlike a Fast Payment Score, this is a full independent assessment across 14 practice areas -- payment behaviour is one input among several, not the whole picture. The review and heatmap below are the outcome of that assessment; no single number is issued, since this diagnostic didn't produce one.
How reliably and transparently the organisation handles payment itself — timing, dispute resolution, and clarity of process.
How easy the organisation is to work with day-to-day — onboarding, purchase orders, invoicing, and reducing risk to suppliers' invoices.
How suppliers are treated directly — access to escalate issues, relationship quality, and fairness of contract terms.
Whether leadership, learning and governance reinforce good supplier practice over time, rather than relying on one team or process.
Fast Payment Score, 0–100 — the line rising means faster, more reliable payment over time; falling means it's slipping.
