Full legal name, billing address, contact person, phone and email. Accurate legal names help match tax, invoicing, and KYC records to avoid payment or tax withholding issues.
Clear description of services, deliverables, and limits of work. Define milestones, acceptance criteria, and any excluded services so later disputes can be resolved against written expectations.
Specify fees, billing cadence, payment method, late fees, and whether tax applies. Include precise numeric amounts or rates rather than vague phrases such as 'reasonable fee'.
State the effective date and, if applicable, end or renewal dates. The effective date often controls billing, delivery windows, and statutes of limitation.
Include printed name, title, company, signature line, and date. Indicate whether electronic signatures are accepted and how consent is recorded.
Include exhibits such as SOWs, rate schedules, or confidentiality addenda referenced by the template and clearly labeled for incorporation by reference.
