Vet S8 Review 2026: Features, Pricing, Pros & Cons

Vet S8 by Modeus is the industry-leading cloud-based digital controlled substance logbook (e-CDR) that eliminates paper logs and automates compliance for veterinary practices. Fully optimized for US DEA regulations and with in-built PMP reporting, Vet S8 also provides seamless compliance tracking for practices across Australia, New Zealand, and the UK. From small general practice clinics and mobile practices, to emergency clinics or university and referral hospitals in the US, UK and Australia, Vet S8 is meticulously designed to keep you compliant 24/7 - whatever the setting. Vet S8 integrates seamlessly with the industry’s most trusted veterinary practice management systems - including ezyVet, Covetrus Ascend, RxWorks, Pulse, Provet, Cornerstone, Digitail, Merlin and Shepherd - eliminating errors by pulling patient and drug info automatically into pre-filled register entries that you simply need to check and sign with a password. This saves significant time by reducing manual data entry and prevents forgotten controlled drug logs. We're trusted globally - in the US, Canada, Australia, UK, & beyond. Originally born out of a strict regulatory environment, Vet S8 is built to scale across international borders. It remains the trusted standard for veterinary compliance in United States (DEA), Australia (S8/S4 regulations), the United Kingdom (VMD and RCVS regulations), and New Zealand. Whether you run a single-doctor clinic or manage an international corporate veterinary group, Vet S8 adapts instantly to country-specific regulatory frameworks. Are you a veterinary group or run multiple practices? We also offer, Modalytics, a centralised platform connected to Vet S8 which allows you to monitor real-time controlled drug activity, and pull group-wide audit reports from a single dashboard.
