Can I sign a handover protocol via zipzipdoc?

Yes. A handover protocol can be created as a standalone document or amendment to the contract. Both parties sign online.

How do I handle payment milestones for long projects?

The works contract includes a payment schedule section. Define milestones (e.g. shell construction, roof, final inspection) with corresponding payments.

Does it work for public procurement contracts?

Public procurement contracts have special requirements. zipzipdoc is suitable for documentation outside formal procurement procedures.

Can I archive contracts for building permit purposes?

Yes. All signed documents are archived with an audit trail. They can be submitted during inspections or permitting.
