# Back-to-back contracting

Mirroring obligations from a head contract into a subcontract so terms flow through consistently down the chain.

## Definição

Back-to-back contracting passes the obligations, risks and timelines a main contractor owes its client through to subcontractors on matching terms. It avoids gaps where the prime is liable upward but cannot recover from the subcontractor, and relies on careful flow-down drafting.

## Exemplo

> A contractor binds its subcontractor to the same delivery dates and penalties it owes the principal, on a back-to-back basis.

## Porque é um risco para a empresa

Where back-to-back terms are not properly flowed down, the prime contractor is caught in a gap: liable to the client for a default it cannot legally recover from the subcontractor. Differences in limitation periods, liability caps or force-majeure definitions between head and subcontract can silently create this gap even where parties intended alignment.

## Como gerir

- Map the head contract obligations before finalising the subcontract to ensure every material obligation is flowed down accurately.
- Pay particular attention to liability caps, liquidated damages, insurance, IP rights and termination rights, as these are the terms most likely to diverge.
- Use defined-term flow-down provisions that incorporate head contract definitions by reference rather than rewriting them.
- Store both the head contract and every related subcontract together so the relationship is visible when an issue arises.
- Review the subcontract whenever the head contract is amended to keep the two in step.

### Como o Contracko ajuda

Contracko allows head contracts and their linked subcontracts to be stored together in the repository, with extracted obligations and deadlines tracked at both levels. When the head contract is amended, teams can locate all related subcontracts instantly rather than relying on filing conventions.

## Perguntas frequentes

Questões comuns sobre este termo.

- **Q:** Does "back-to-back" mean the subcontract must be identical to the head contract?
  **A:** Not identical, but the material obligations, timelines and risk allocation that the prime owes the client should be mirrored. Adjustments for subcontract-specific matters are normal, provided they do not create a gap in liability.

- **Q:** What is a flow-down clause?
  **A:** A clause in a subcontract that incorporates all or specified terms of the head contract by reference, ensuring the subcontractor is bound to the same obligations as the prime.

- **Q:** What is the biggest practical risk in back-to-back contracting?
  **A:** Mismatched liability caps or limitation periods, where the prime is exposed for longer or in greater amounts than it can recover from the subcontractor, creating an uncovered gap.

- **Q:** How do you handle a back-to-back arrangement when the head contract changes?
  **A:** Any material amendment to the head contract should trigger a review of the subcontract and, where necessary, a corresponding amendment to maintain alignment. Neglecting this step is how gaps silently form.

- **Q:** Can a subcontractor be held liable directly by the client?
  **A:** Generally no: the client's contract is with the prime and there is no direct legal relationship with the subcontractor unless a collateral warranty or direct agreement has been put in place.
