How to Write an Agency Master Services Agreement (MSA) That Actually Protects You

Every agency owner remembers their first "nightmare client."

You know the one. The client who asked for "just one more tiny revision" twelve times. The client who paid their invoice 45 days late because "accounting was on vacation." The client who assumed your web design package also included managing their social media for free.

If you don't have a solid Master Services Agreement (MSA) in place, you don't have a business—you have a very stressful, very fragile hobby.

An MSA is the foundation of every professional agency-client relationship. It sets the boundaries, protects your profit margins, and ensures you actually get paid for the work you do. In this guide, we'll walk through exactly what needs to be in your agency's MSA and how to stop chasing clients for signatures.

What is a Master Services Agreement (MSA)?

A Master Services Agreement (MSA) is a foundational contract between your agency and your client. Instead of writing a massive, 20-page contract every single time you do a new project, you use an MSA.

The MSA covers all the standard legal stuff—payment terms, intellectual property, confidentiality, and dispute resolution. It governs the overall relationship.

Then, for specific projects, you just create a brief Statement of Work (SOW) that says "We will build a 5-page website for $5,000," and at the bottom, it simply states: "This SOW is governed by the terms of the MSA signed on [Date]."

This two-document system saves you countless hours of legal review and makes it incredibly easy to start new projects or upsell retainers to existing clients.

7 Crucial Elements of a Bulletproof Agency MSA

While you should always have a lawyer review your final contract, every good agency MSA needs to cover these seven core areas.

1. Payment Terms and Late Fees (The "Get Paid" Clause)

Never leave payment terms vague. Your MSA needs to explicitly state:

  • When invoices are due: (e.g., Net-15 or Net-30). We highly recommend "Due upon receipt" for deposits and Net-15 for milestones.
  • How you accept payment: (Credit card, ACH, Wire transfer).
  • Late fee penalties: "Invoices unpaid past 30 days will accrue interest at a rate of 1.5% per month." Even if you never enforce the late fee, having it in the contract gets you paid faster.
  • The "Tools Down" policy: Explicitly state that if an invoice is X days late, all project work immediately stops until the balance is paid.

2. Scope Creep and Revisions (The "No Free Work" Clause)

Scope creep is the silent killer of agency profit margins. Your MSA must define how changes are handled.

  • State that any work outside the attached Statement of Work (SOW) requires a formal Change Request and will be billed at your standard hourly rate (e.g., $150/hr).
  • Define what constitutes a "revision" and how many are included.
  • Pro Tip: If you use TryApprove, you can manage these approvals and change requests directly in the client portal, completely eliminating the "he said, she said" of email feedback.

3. Intellectual Property (IP) Ownership

Who owns the work you create? Most agencies operate on a "transfer upon full payment" model. Your MSA should explicitly state that your agency retains all rights, title, and interest in the deliverables until the final invoice is paid in full. Once the client pays, the IP transfers to them. This is your ultimate leverage if a client tries to run off with your designs without paying the final bill.

4. Client Responsibilities and Delays

A project is a two-way street. If you are building a website, but the client takes six weeks to send you their brand assets, the project stalls, and you don't get paid your final milestone. Include a clause that outlines:

  • The client must provide feedback or assets within X business days.
  • If the client goes dark for more than X days, the project is put on hold, and a "restart fee" may apply to resume work.
  • If the client causes a delay of more than 30 days, you have the right to invoice for all work completed up to that point.

5. Confidentiality (NDA)

Most corporate clients will want a Non-Disclosure Agreement. Baking a standard confidentiality clause directly into your MSA saves you from having to sign a separate NDA for every new client. It protects their trade secrets, and it protects your proprietary agency processes.

6. Portfolio Rights (The "Showcase" Clause)

You do great work, and you need to show it off to get more clients. But some corporate clients assume you can't share the work publicly. Include a clause that gives your agency the right to display the completed work in your portfolio, on your website, and in marketing materials (unless they explicitly pay a premium for a complete white-label NDA).

7. Termination

Things don't always work out. If the relationship turns toxic, you need an eject button.

  • Detail how either party can cancel the contract (e.g., 30 days written notice).
  • Specify that if the client cancels, they must pay for all work completed up to the date of cancellation.
  • State that deposits are non-refundable.

The Problem with Traditional Agency Contracts

Knowing what goes into an MSA is only half the battle. The other half is the friction of actually getting it signed.

Here is the standard, exhausting agency onboarding workflow:

  1. You export your MSA to a PDF.
  2. You upload it to DocuSign or HelloSign.
  3. You email it to the client.
  4. You wait.
  5. You follow up three days later.
  6. The client signs it.
  7. Now you have to send them a separate email with a Stripe link to pay the deposit.
  8. Then you send them another email with a Google Form to collect their onboarding assets.

It's messy, it looks unprofessional, and it creates massive friction before the project even begins.

A Better Way: Automating Your MSA with TryApprove

Instead of juggling PDFs, e-signature software, invoicing tools, and intake forms, modern agencies are moving to all-in-one onboarding flows.

With TryApprove, you can turn your MSA into a seamless, high-converting onboarding experience:

  1. One Unified Flow: You create an Onboarding flow that includes your MSA, your intake questionnaire, and your deposit invoice.
  2. Branded Experience: You send the client one magic link. They open a beautiful portal stamped with your logo and your brand colors.
  3. No Logins Required: The client doesn't have to create an account. They just review the MSA, click "Accept", fill out their onboarding questions, and pay the deposit via credit card—all on a single screen.

When you remove the friction from signing the MSA, projects start faster, you get paid sooner, and you set a highly professional tone from day one.
