Before Signing Your First Customer

Signing your first customer is an important milestone for any growing business. Whether you are launching a marketing agency, consulting firm, software company, or professional services business, obtaining that first customer represents an opportunity to begin generating revenue and building long-term business relationships.

However, before providing services, businesses should consider how those relationships will be documented. A handshake, informal email exchange, or basic invoice may leave important questions unanswered concerning payment, service obligations, intellectual property, and what happens when disagreements arise.

For many service-based businesses, three contractual documents can help establish a more organized approach to customer relationships: a Master Services Agreement (MSA), Customer Order Form, and Statement of Work (SOW).

Not every business requires all three documents. Depending on the services offered, the appropriate contractual structure may involve one agreement or several coordinated documents.

1. Master Services Agreement: Establishing the Legal Relationship

A Master Services Agreement (MSA) establishes the general contractual terms governing the relationship between a business and its customers.

Rather than drafting an entirely new agreement for each customer, businesses can develop standardized terms addressing common legal and commercial considerations.

An MSA may address payment obligations, confidentiality, intellectual property ownership, warranties, limitations of liability, indemnification, termination rights, and dispute resolution.

For example, a marketing agency may establish contractual provisions explaining who owns completed creative materials, what happens when a customer fails to pay, and how either party may terminate the relationship.

These provisions help define expectations and allocate contractual responsibilities before disagreements arise.

Importantly, an MSA should reflect how the company actually operates. A generic agreement that does not account for the business's services, customer responsibilities, or operational limitations may leave important contractual issues unresolved.

2. Customer Order Form: Defining What the Customer Purchases

While the MSA establishes the general contractual framework, a customer order form identifies the specific services or products being purchased.

An order form commonly includes the customer's legal name, selected services, pricing, billing arrangements, service commencement date, and applicable commitment period.

Consider a marketing agency offering three subscription packages at different monthly prices. The agency may use the same MSA for its customers while issuing individual order forms identifying which package each customer has selected.

This approach allows businesses to maintain consistent contractual terms while accommodating different service offerings and customer arrangements.

The order form should also clearly identify the applicable MSA and address how the documents operate together, including which provisions control when their terms conflict.

For additional drafting considerations, see our guide to Customer Order Form Drafting.

3. Statement of Work: Establishing Project Expectations

A Statement of Work (SOW) defines the specific work a service provider agrees to perform for a particular project or engagement.

An SOW may identify project objectives, deliverables, timelines, milestones, customer responsibilities, acceptance criteria, and procedures for approving additional work.

For example, a software development company hired to create a customer portal may use an SOW to describe the required functionality, development phases, testing procedures, and delivery schedule.

Clearly defining these requirements can help reduce uncertainty concerning the work included in the project and the standards used to evaluate completion.

An SOW can also help address scope creep, which occurs when additional customer requests expand beyond the originally agreed services.

By establishing procedures for approving changes, adjusting compensation, and modifying project timelines, businesses can create a more predictable process for handling additional work.

Do You Really Need All Three Documents?

Not necessarily.

A business providing standardized monthly services may find that an MSA and order form adequately document its customer relationships.

A company delivering customized projects may benefit from an MSA accompanied by individual SOWs. In some circumstances, a single services agreement containing the relevant commercial terms and project specifications may be sufficient.

The important consideration is not the number of documents a business uses, but whether its contractual framework adequately addresses the services being provided, the parties' responsibilities, and the commercial risks associated with the relationship.

Where multiple documents are used, they should be coordinated to avoid inconsistent provisions or uncertainty concerning which terms govern.

Start with a Clear Contractual Foundation

Customer contracts should do more than establish how much a business will be paid. They can define service expectations, establish customer responsibilities, address ownership of work, and allocate certain risks associated with the relationship.

Although properly drafted agreements cannot guarantee that disputes will be avoided or liability eliminated, they can help businesses establish clearer expectations and more consistent contracting practices.

Before signing your first customer, consider whether your agreements accurately reflect your services, operational capabilities, and business model.

A clear contractual foundation can help businesses focus on delivering their services while managing the legal and commercial responsibilities that come with customer relationships.
