Frequently asked questions
- Is a signed proposal enough legally?
- It can form a basic contract for simple work, but dedicated terms on IP, liability, and termination protect you on larger US engagements.
- MSA or project contract for one job?
- One combined project contract is fine for single engagements. MSA plus SOW suits repeat clients and enterprises.
- Who signs first?
- Either party via e-sign is fine. You sign when sending or counter-sign after client—consistency matters more than order.
- When do I invoice the deposit?
- Immediately upon fully executed contract unless you agreed deposit with proposal acceptance earlier.
- What if scope changed after the proposal?
- Update the SOW before signature. Never start work on outdated proposal language.
- Can clients use their own contract?
- Often yes for enterprise. Negotiate SOW attachment, payment terms, and IP transfer timing carefully.
- Do I need a lawyer for every contract?
- Use vetted templates for routine work. Have an attorney review your master template and any high-liability or large deals.
- How do e-sign tools fit in?
- DocuSign, HelloSign, and PandaDoc provide audit trails US clients trust. Store completed copies in your project folder.
- What goes to onboarding after signing?
- Welcome email, onboarding checklist, asset requests, access forms, and kickoff calendar invite once deposit clears.
