Contracts

Contracts are the primary rate structure in OpenTug. They define the commercial agreement between a customer and a provider, including validity dates, rate terms, demurrage, and contractual metadata. All towing activity (Tows) ultimately roll up to a parent Contract.

Creating a Contract

Navigate to Rates → Contracts and click New Contract.

Basic Information

• Contract Name – Internal-facing name used across rates and voyages

• Contract Type – Term Dedicated, COA, Spot, or Flex

• Customer Company – Customer associated with the contract

• Carrier – Towing provider tied to the agreement

Key Concept

Contracts define the commercial relationship. They do not need to represent a single lane or asset set — that granularity lives at the Tow level.
