Vern vs Ivo

Put the review in the hands of your business team.
Choose Vern when operations, finance or recruitment needs to get incoming contracts agreed. Your playbook sets the standard.

For the UK team handling the deal.
Vern brings a UK Client Terms starting playbook and your own commercial positions into the review. Your team can maintain its preferred wording and fallbacks, with optional setup support from the Vern team at AssurePath.

Through every round
A concession is only useful if it gets you closer to your terms.
Imagine a client accepts your payment period but adds a wider right to withhold invoices. Vern compares the changed clauses and re-scores the new draft against your playbook. Your team can see where the agreement has improved and where the revised wording needs attention.
Keep each draft with the same negotiation and you can look back at earlier reviews before making the next decision. You have a record of how the deal moved, alongside suggested wording to take it forward.
