What Is an Independent Contractor Agreement?
An Independent Contractor Agreement (ICA) is the contract between you and the platform or client you work through. It defines the terms of your engagement: what you will do, what you will be paid, who owns the work you produce, what happens if either party wants to end the relationship, and what obligations continue after the engagement ends.
Unlike an employment contract, an ICA establishes you as a self-employed contractor, not an employee. This has specific legal implications: you are responsible for your own tax, you do not receive statutory employment benefits, and the client retains the right to work with other contractors simultaneously.
An ICA is a legal document. This guide explains common clauses in plain English, it is not legal advice. If you have concerns about a specific clause, consult a lawyer in your jurisdiction before signing.
IP Ownership: The Most Important Clause
Intellectual property clauses in ICAs typically assign ownership of all work created during the engagement to the client. This is standard and expected, the client is paying for the work product and requires ownership of it to operate their business. What this means in practice: any code, documentation, designs, or other deliverables you create as part of the engagement belong to the client, not to you.
What to look for: ensure the IP clause is limited to work created specifically for the client during the engagement. A clause that attempts to assign pre-existing intellectual property, tools you already owned, open source libraries you developed previously, or knowledge you bring to the role, is unreasonably broad and worth querying.
- Work-for-hire clauses are standard, all deliverables created for the client belong to the client.
- Pre-existing IP carve-outs protect tools and code you owned before the engagement, check these are present.
- Open source contributions: if you plan to contribute to open source projects based on general knowledge from the engagement (not client-specific code), ensure the ICA does not prohibit this.
Payment Terms and Invoicing
Payment terms define when you are paid relative to when the work is done and invoiced, and they vary widely between companies. Whoever you contract with, read this section of the agreement before you sign rather than after you start, and make sure you understand it against your own outgoings.
The agreement should specify the payment currency, the payment frequency, the invoice submission deadline within each period, and the payment method. If any of those are vague or missing, ask for them in writing before signing.
Scope of Work and Deliverables
The scope of work clause defines what you are being engaged to do. In most professional ICAs for software engineers, this is framed broadly (e.g., 'software engineering services as directed by the client') rather than specifying individual deliverables. This is normal for ongoing engagements.
Watch for scope clauses that are unreasonably wide, for example, clauses requiring you to perform any task the client requests regardless of whether it falls within your professional discipline. These are rare in professional contracts but worth noting.
Termination and Notice Periods
Termination clauses define how the engagement can be ended by either party. A professional agreement gives notice on both sides, in writing, so that neither party can be left without warning. Check the period stated in your own agreement and that it applies equally in both directions.
Some ICAs include provisions for immediate termination for cause, serious breaches such as confidentiality violations, fraud, or material failure to perform. These are reasonable. Ensure 'for cause' is defined specifically in the contract rather than left to broad interpretation.
Non-Compete and Non-Solicitation
Non-solicitation clauses typically prohibit you from directly approaching the client's other contractors, employees, or clients during and for a period after the engagement. These are standard and reasonable.
Non-compete clauses, prohibiting you from working with competitors of the client during or after the engagement, vary widely in scope. A clause preventing you from working in the same broad industry for 12 months after an engagement ends is unreasonably wide for a contractor relationship. A clause preventing you from working directly with a named client's direct competitors during the active engagement period is more defensible.
Non-compete enforceability varies by jurisdiction. In many countries, overly broad non-compete clauses are unenforceable. However, if you are concerned about a specific clause, seek legal advice rather than simply assuming it will not apply.
Confidentiality Obligations
Confidentiality clauses require you not to disclose the client's proprietary information, their codebase, architecture, business strategies, client data, or financial information, to third parties during or after the engagement. These are entirely standard and apply throughout your career.
- Do not discuss client systems, codebase, or architecture in public forums, on social media, or in job applications without explicit permission.
- Do not retain client code, data, or documentation on personal devices beyond what is necessary for the engagement.
- If in doubt about whether something is confidential, treat it as confidential until you receive explicit written permission to share it.
