TL;DR: A white-label development partner builds the website or software, and your agency delivers it under its own name and contracts. It works when four things are written down before work starts: who talks to the client, who owns the code, who holds the logins, and the quality and security bar the work must clear.

A white label development partner is the engineering team behind an agency's name. The agency sells the project, owns the client relationship and puts its brand on the result. The partner writes the code and, when the engagement calls for it, hosts and maintains what it built. For a marketing, design or IT agency in Massachusetts that sells websites or software it does not build in house, this is how the work gets delivered.

What goes wrong is rarely the code. It is a missing contract sentence, a domain in the wrong name, or a client emailing the developer directly.

What does a white-label development partner actually do?

The partner builds the site, application or system, the agency delivers it as its own work, and the partner stays out of the client relationship unless the agency brings it in. In a referral or co-branded arrangement, by contrast, the client knows both firms.

The work is ordinary development work: custom web applications, storefronts, integrations and the infrastructure underneath them. What changes is who faces the client. The agency writes the proposal, runs the meetings and sends the invoice. The partner works through the agency's channels. Done well, the client sees one team.

Why do agencies use white-label development instead of hiring?

Usually because demand is real but uneven. A full-time developer is a fixed cost; a white label development partner is capacity that follows the work.

The fixed cost is not small. The median annual wage for web developers in the United States was $92,650 in May 2025, before benefits, equipment and the time it takes to recruit. (U.S. Bureau of Labor Statistics, Occupational Outlook Handbook) And one developer rarely covers front end, back end, security and hosting on the same project.

The other reason is focus. An agency strong in strategy, brand or managed IT can use white label development to fill the engineering gap without becoming a software company. We wrote more about that trade in build the team or find the partner.

How are the work and client communication split?

Write this down before the first white label development project, not during it. A one-page agreement on roles prevents most of the friction I see in white label development partnerships:

The agency owns the client relationship and the partner owns the build; write the split down first.
  • The agency owns the relationship. Sales, the client contract, meetings, invoicing and every message the client receives.
  • The partner owns the build. Technical scoping, code, review, testing, deployment and, where agreed, hosting.
  • Requirements flow one way. Client to agency to partner. A partner who takes change requests straight from your client is rewriting your scope.
  • Handback is defined. Working software on a staging site, a change log, documentation in the agency's format, and the access the agency needs.
  • Escalation is named. Who answers when a live site goes down at 7pm, and how the agency hears first.

One more line belongs in every white label development brief: no partner branding anywhere the client can see it, from the site footer to the admin login screen.

What should the contract say about IP, confidentiality and non-solicitation?

Have a Massachusetts attorney review this part before you sign. What follows is plain-language background, not legal advice.

In white label development, ownership of the code needs an assignment in writing

Paying for code is not the same as owning it. Copyright "vests initially in the author or authors of the work." (17 U.S.C. 201) The exception is a "work made for hire," where the hiring party is treated as the author.

The U.S. Copyright Office explains that a work is made for hire in two situations: "when the work is created by an employee as part of the employee's regular duties" and "when a certain type of work is created as a result of an express written agreement" with the party commissioning it. (U.S. Copyright Office, Circular 30, revised August 2024) That "certain type" is a closed list of nine: a contribution to a collective work, part of a motion picture or other audiovisual work, a translation, a supplementary work, a compilation, an instructional text, a test, answer material for a test, or an atlas. (17 U.S.C. 101) The Copyright Office is blunt about the result: "If a work fails to satisfy any of these requirements, it is not a work made for hire."

Custom software and website code are not on that list. So a contract that only says "work made for hire" may not transfer what the agency thinks it does. The dependable route is an assignment. Federal law says a transfer of copyright ownership "is not valid unless an instrument of conveyance, or a note or memorandum of the transfer, is in writing and signed by the owner of the rights conveyed." (17 U.S.C. 204)

In practice, the agreement with your white label development partner should cover:

  • A written, signed assignment of the project code and assets to the agency, or directly to the end client if that is what your client contract promises.
  • Matching terms on both sides. The rights the partner assigns to you must be at least as broad as the rights you promise your client.
  • Pre-existing tools and open source. Components the partner already owned can stay theirs with a permanent license for the project. Open-source parts are listed with their licenses. Brian mapped what GPL and AGPL licenses require when you ship or host the code (opens in a new tab).

Confidentiality and non-solicitation

A mutual confidentiality agreement covers your clients and pricing and the partner's methods, and says what happens to client data at the end: returned, deleted, confirmed in writing. The non-solicitation clause that protects the agency is simple: the partner will not pitch or take work directly from the agency's clients, during the relationship and for a reasonable period after.

Be careful with clauses where the two firms agree not to hire each other's staff. The FTC and the Department of Justice have said that "agreements not to poach employees" are among the practices that can carry criminal liability under antitrust law. (FTC, January 16, 2025) Have your attorney word any staffing clause, or leave it out.

Your client's rules flow down to the partner

Read your own client contract before you sign a white label development agreement. Some require consent before you subcontract, or carry security obligations that must pass to anyone who touches the data. I wrote about how security obligations flow down through vendor contracts (opens in a new tab), and the short version is that you cannot hand a partner fewer obligations than you accepted.

Health data is the clearest case. Under the HIPAA rules, a business associate may let a subcontractor handle protected health information only "if the business associate obtains satisfactory assurances" that "the subcontractor will appropriately safeguard the information." (45 CFR 164.502) For a medical or dental client, that means a written agreement with your partner too.

What quality and security standards should a partner build to?

"Good code" is not a standard. Name real ones in the white label development agreement, so both sides check the work against the same list.

Name real standards in the agreement so both sides check the work against the same list.
  • Application security. The OWASP Application Security Verification Standard provides "a basis for testing web application technical security controls" and gives developers "a list of requirements for secure development." (OWASP ASVS) Agree which level applies to which project.
  • Development practices. NIST's Secure Software Development Framework describes "a core set of high-level secure software development practices," and gives buyers and suppliers "a common vocabulary for secure software development." (NIST SP 800-218)
  • Accessibility. WCAG 2.2 "covers a wide range of recommendations for making web content more accessible." (W3C, WCAG 2.2) Name the level you are testing to, and ask for the test results with the handback.
  • A definition of done. Tests pass, code is reviewed by someone other than its author, dependencies are current, the site works on a phone, and nothing ships without a staging review.

You can check some of this yourself: the free security headers checker on kief.dev (opens in a new tab) shows whether a launched site sends basic browser protections. For anything handling payments or personal data, plan an authorized penetration test before launch.

Who should host the site and hold the logins?

The FTC's advice to small businesses hiring a web host applies directly here: "Clarify from the beginning who will manage your website after it's built." (FTC, Cybersecurity for Small Business) In white label development there are three parties, so the question has three answers.

Decide up front who hosts the site and who holds each login, and put the client's name on the accounts.

Hosting can sit with the partner, the agency or the end client. What matters is that the accounts that control the business belong to the right party, never to one person's personal email:

  • The domain registration and DNS belong to the end client, or to the agency on the client's behalf, in a company account with two people who can sign in.
  • The code repository lives where the owner of the code can always reach it, ideally in the agency's or client's organization with the partner added as a member.
  • Hosting, email and payment accounts are in the name of whoever pays for them long term.
  • The partner gets its own named accounts, never a shared admin password, so access can be removed person by person.

The FTC's vendor guidance says to "limit access to a need-to-know basis, and only for the time the vendor needs to do the job," and to "make vendors take additional steps beyond just logging in with a password." (FTC, Cybersecurity for Small Business)

We keep an explainer on who owns the website and the login, and I went further in who owns the site, the host, and the login (opens in a new tab). If the partner will host, ask what kind: our note on shared versus managed hosting explains why it matters.

How do you vet a white-label development partner?

Treat it like hiring a senior employee you cannot easily replace mid-project. I keep a longer guide to evaluating a technology vendor (opens in a new tab); for white-label development, these questions matter most:

  1. Will you sign a written IP assignment and a mutual confidentiality agreement before work starts?
  2. Who will actually write the code? You should know every party that touches your client's data.
  3. Can we see work you are allowed to show? A white-label partner may not be allowed to name clients, but can walk you through a build or a code sample with details removed.
  4. How do you test, review and ship? Listen for specifics: automated tests, peer review, staging sites, a rollback plan.
  5. How do you handle security? Which standards, how secrets are managed, and how you hear about an incident.
  6. What happens when we part ways? Code, credentials and data come back on a written timeline. My notes on vendor contract exit terms (opens in a new tab) list what to ask for.
  7. Can we start with one small, paid project? A two to four week build shows communication, quality and honesty faster than any sales call.

What are the red flags in a white-label development partnership?

  • The partner resists a written IP assignment, or offers only a license to the code your client paid for.
  • The partner wants to register the client's domain or hosting in its own name.
  • Everyone shares one admin login, or the partner will not use multi-factor authentication.
  • The partner's name or logo appears in the site footer, the admin screen or the outgoing email.
  • A developer contacts your client directly, even to be helpful.
  • There is no written definition of done, and "launched" is the only test.
  • Questions about security get a reassurance instead of a process.

Two or three together are a reason to keep looking. Our note on vendor lock-in covers the longer term risk.

What does this look like for an agency in Central Massachusetts?

Most agencies here are small. Worcester County had 47 advertising, public relations and related establishments with employees in 2023, and 34 of them had fewer than five employees. The county also had 22 graphic design establishments with employees, 21 of them under five people. (U.S. Census Bureau, County Business Patterns 2023) A five person studio does not need a full engineering bench.

Massachusetts adds one rule every agency should know. A business that owns or licenses personal information about Massachusetts residents must oversee service providers by "taking reasonable steps to select and retain third-party service providers" able to protect it, and "requiring such third-party service providers by contract to implement and maintain such appropriate security measures." (201 CMR 17.03) If a site you deliver stores personal information as the regulation defines it, the contracts in the chain should say so. The background is in my post on Massachusetts WISP requirements (opens in a new tab).

For example, a design studio in Worcester might sell a membership site with online payments to a local nonprofit, and use white label development to have a partner build and host it under the studio's name. The chain then needs an assignment from partner to studio, a client contract passing ownership to the nonprofit, security terms at each step, and domain and payment accounts in the nonprofit's own name. Written once, the same documents carry the next project.

Frequently asked questions

What is a white-label development partner?

A firm that builds websites, applications or systems that an agency delivers under its own brand and contracts. The agency keeps the client relationship; the partner does the engineering.

Who owns the code in white-label development?

Under federal copyright law, the author owns it first. Custom software is not one of the nine kinds of work a contract can make "for hire," so the agency needs a written assignment signed by the partner, matched to what the agency promises its own client.

Will my clients know I use white-label development?

Not from the partner, if the agreement says so. Check your own client contract, though: some require consent before subcontracting, and regulated data such as health records needs written agreements with every party that handles it.

Should the white-label partner host the client's site?

It can, under the agency's name. Account ownership matters more: the domain, DNS and repository belong to the client or agency, and the partner signs in with its own named accounts and multi-factor authentication.

What should a white-label development agreement include?

Scope and handback, a signed IP assignment, mutual confidentiality, a client non-solicitation clause, named quality and security standards, account ownership, incident notice, and exit terms that return code, credentials and data on a set timeline.

How do I test a white-label development partner before committing?

Start with one small paid project of two to four weeks. Judge how they communicate, whether they meet the written definition of done, and how they handle a change request.

Where we fit

Kief Studio is in Shrewsbury, and white-label development is our service for agencies and studios. We build it. Your name stays on it. We build the site, application or system, your agency delivers it under its own name, and we stay out of the client relationship unless you bring us in.

It fits agencies and studios with more client work than build capacity: custom web applications, storefronts, integrations and the infrastructure behind them. We agree scope, standards and how we hand work back to your team, then build to your brand, your contracts and your client's requirements. When the engagement includes it, we host and maintain the work under your name on dedicated infrastructure, with managed hosting on LTFI (opens in a new tab). No shared hosting. If you would rather have us in front of your client as a co-brand, that is a different arrangement, and we are happy to talk about it.
