# Contracts & invoices
Lemon.io legal and billing framework for client-developer engagements. IP terms, MSA options, billing cycles, and payment structure.
Lemon.io manages **all services around collaboration** between a client and a remote developer: contracts, invoices, NDAs, and other legal paperwork for both parties — clients and engineers.
Companies do not need to draft or negotiate agreements directly with the IT engineers:
* Lemon.io's standard terms of use **govern intellectual property** — all IP created during the engagement belongs to the client by default. Deliverables are treated as work made for hire and become the client’s property upon full payment.
* An **MSA (Master Service Agreement)** or additional documents can be signed with the developer if a client’s legal team requires it.
* Lemon.io handles **bank invoices** based on your billing cycle.
* **Developers are paid by Lemon.io directly** — clients do not handle developer compensation.
