About ViroOne

How we work
Our work is centered around a “clause map”: a structured view of definitions, duties, dates, conditions, and exceptions. This makes it easier to discuss documents with counterparties and to keep track of versions.
Business model (plain description)
ViroOne provides professional services based on an agreed scope. The scope explains what documents are covered, which deliverables you receive, and what information we need from you.
- We are compensated by clients for the agreed work under the selected scope.
- We aim to keep communications neutral and scope-driven.
- We do not position ourselves as a marketplace and do not publish “rankings” of counterparties.
If your situation requires additional materials or a different workflow, we clarify options before any expansion of scope.
Typical documents (examples)
Depending on the property type and counterparties, documents may include:
- Purchase agreement drafts and attachments
- Disclosure / explanation materials (when provided)
- Condominium rules, management materials, and notices
- Hand-over items list and meeting notes
If you’re unsure what you have, send what you received and we’ll help identify the set.
