What Is A Sales Agency Agreement? (2026 Updated)

If you’re growing your business and want to sell more without hiring a full internal sales team, using a sales agent can be a smart (and scalable) move.

But before anyone starts pitching your products, chasing leads, or negotiating with customers on your behalf, you’ll want the relationship clearly set out in writing. That’s where a Sales Agency Agreement comes in.

This guide is updated to reflect current, practical expectations in New Zealand-especially as more sales relationships happen online, across regions, and through contractors rather than employees.

Let’s break down what a Sales Agency Agreement is, when you need one, what to include, and how to avoid the common traps.

What Is A Sales Agency Agreement?

A Sales Agency Agreement is a contract where your business (the principal) appoints another person or business (the sales agent) to promote and/or sell your goods or services-usually in exchange for commission.

In plain terms, it answers key questions like:

• What is the agent allowed to do when dealing with customers?
• How do they get paid (and when)?
• Who owns the customer relationships and data?
• What happens if the relationship ends?

A well-drafted Sales Agency Agreement protects both sides. For you, it helps ensure the agent represents your brand properly and you’re not paying commission you don’t owe. For the agent, it gives clarity on commission, territory, and expectations-so they can confidently invest their time and effort.

Sales Agent vs Distributor (Quick Difference)

People often mix up “sales agents” and “distributors”, but they’re usually quite different:

• Sales agent: finds customers and helps make sales on your behalf. You typically invoice the customer, and the agent earns commission.
• Distributor/reseller: buys your products and resells them (often setting their own resale price). They make money on the margin, not a commission.

If you’re appointing someone to sell but they’ll actually be reselling (or holding stock), you may need a different structure and contract terms-because the legal and commercial risks change.

When Do You Need A Sales Agency Agreement?

You should consider a Sales Agency Agreement any time another person or business is going to represent you in sales conversations, generate leads, or negotiate deals-especially if there’s commission involved.

Common scenarios include:

• You’re expanding into a new region (e.g. South Island coverage) and want a local agent.
• You’ve created a product and want someone with existing relationships to introduce it to retailers or commercial customers.
• You run a service business (like marketing, IT, consulting, training) and want a commission-based salesperson to bring in clients.
• You’re partnering with an “industry connector” who will open doors, arrange meetings, and help close deals.

Even if you trust the person, don’t rely on “we’ll sort it out later”. Sales relationships move fast, and disputes around commission and customer ownership are some of the most common issues we see.

If You’re Using A Contractor Salesperson

Many businesses engage sales agents as contractors rather than employees, because it can be more flexible and cost-effective.

That said, you’ll want to be clear about the nature of the relationship. If you intend them to be a contractor, your documents and real-world working arrangement should line up-otherwise you may run into risk around employment entitlements and disputes.

Depending on your setup, it might be more appropriate to use a contractor-style agreement alongside (or instead of) a sales agency structure. Sometimes, businesses also use a broader Service Agreement with a commission schedule attached.

What Should A Sales Agency Agreement Include?

A good Sales Agency Agreement isn’t just a formality-it’s a practical operating manual for how sales will happen and how money flows.

Here are the key clauses you’ll usually want to include.

1. Appointment Scope: What The Agent Can (And Can’t) Do

This is where you define the agent’s authority. For example:

• Can they only introduce leads, or can they negotiate and close?
• Can they agree to discounts, special terms, or bundled offers?
• Are they allowed to sign contracts on your behalf-or must you approve all deals?
• Do they have a specific process to follow (e.g. using your CRM, proposal templates, approval workflows)?

This matters because under general principles of agency, an agent’s actions can sometimes bind a principal-especially if you’ve given them apparent authority. It’s much safer to set boundaries upfront.

2. Territory, Market Segment, And Exclusivity

Most sales agency disputes come down to “who owns the customer” or “who gets paid for this deal”. Clear boundaries help avoid that.

You might define:

• Territory: Auckland only, nationwide, specific regions, or online-only.
• Customer type: retail, wholesale, corporate, government, SMEs, specific industries.
• Exclusivity: is the agent your only agent for that territory/segment, or non-exclusive?

If you do grant exclusivity, you’ll usually want performance obligations (like minimum targets) and a right to revoke exclusivity if targets aren’t met.

3. Commission Structure And Payment Triggers

This is the heart of the agreement, and it needs to be drafted carefully.

Typical commission questions include:

• How is commission calculated? A percentage of revenue, gross profit, or a fixed amount per sale?
• When is commission earned? On contract signing, on invoice, or only when you receive payment?
• What happens with refunds, cancellations, chargebacks, or non-payment?
• Do renewals count? For example, recurring subscriptions or ongoing service retainers.
• Are there different rates for new customers vs existing customers?

If you’re thinking “we’ll keep it simple and just pay a percentage”, it’s still worth spelling out the mechanics. Ambiguity around commission is a fast track to disputes-particularly when a deal involves multiple touchpoints, long lead times, or handover to account managers.

If you’re paying commission to staff rather than an external agent, you may also want to align your approach with a tailored commission-only structure (where appropriate) so you’re not accidentally creating confusion between employment and agency arrangements.

4. Leads, Sales Pipeline, And Customer Ownership

In many industries, your customer list is one of your most valuable business assets.

Your agreement should cover things like:

• Who “owns” the lead and customer relationship during the term and after termination.
• Whether leads must be recorded in your CRM within a certain time.
• Whether the agent can continue dealing with those customers after the agreement ends.
• Whether the agent can market to your customers for other offerings.

This links closely to confidentiality and restraint obligations (we’ll cover those shortly).

5. Brand Use, Marketing Rules, And Fair Trading Compliance

When someone sells for you, they’re representing your brand. If they make misleading claims-intentionally or not-your business may wear the consequences.

In New Zealand, the Fair Trading Act 1986 prohibits misleading and deceptive conduct in trade, including false claims about products, pricing, or performance.

So, your Sales Agency Agreement often needs rules about:

• Approved marketing materials and messaging.
• Prohibited claims (e.g. “guaranteed results” where that’s not accurate).
• How pricing and discounts can be described.
• How comparisons with competitors are handled.

If you sell to consumers (not just businesses), you’ll also want to keep the Consumer Guarantees Act 1993 in mind, because it sets certain minimum guarantees for consumer purchases that can’t be contracted out of in many cases.

6. Term, Renewal, And Termination

Most Sales Agency Agreements will specify:

• The start date and whether it’s a fixed term or ongoing.
• Any trial period (if applicable).
• When and how the agreement can be terminated (for convenience, or only for breach).
• Immediate termination events (e.g. serious misconduct, misleading statements, insolvency, reputation damage).

The termination section should also tie into what happens to commission after the relationship ends-which is a major source of disagreement if it’s not clearly addressed.

7. Post-Termination Commission (The “Tail”)

It’s common for agents to ask for a “tail” commission-meaning they get commission for deals that close after termination, if they introduced or substantially developed the opportunity during the term.

This can be reasonable, but it needs boundaries. For example:

• A defined period (e.g. 3–12 months).
• A clear rule about what qualifies (e.g. opportunities logged in the CRM before termination).
• Whether commission applies to renewals, upsells, or expansions.

This is one of those areas where getting the drafting right upfront can save you a lot of time (and awkward conversations) later.

8. Confidentiality And Restraints

You’ll usually want the agent to keep your sensitive information confidential, including:

• Pricing strategies and margins
• Customer lists and pipeline
• Supplier terms
• Sales scripts, proposals, and internal processes

This is often dealt with through a confidentiality clause (and sometimes a separate NDA). Depending on the risk, you might also include restraints-such as non-solicitation of your customers for a period after termination.

These clauses need to be reasonable and tailored. Overly broad restraints can be hard to enforce, while overly weak ones don’t protect you when it matters.

In some cases, your broader business terms and legal docs may also need to align-especially if the agent will access systems and data governed by workplace policies, privacy rules, or information security requirements.

What Laws And Compliance Issues Should You Keep In Mind In New Zealand?

A Sales Agency Agreement is commercial, but it still sits within the wider legal framework in NZ. These are the main areas to keep on your radar.

Fair Trading Act 1986

As mentioned above, misleading claims in sales and marketing can expose your business to real risk.

That includes:

• False representations about price, quality, or performance
• Misleading “limited time” offers
• Unsubstantiated claims (e.g. “clinically proven” where you don’t have evidence)

Your agreement should require the agent to comply with your instructions and the law, and it should give you a way to step in quickly if there’s a compliance issue.

Privacy Act 2020 (Especially With Leads And CRMs)

If your sales agent collects personal information (names, emails, phone numbers, job titles, customer notes), you need to think about privacy compliance.

Under the Privacy Act 2020, you must take reasonable steps to protect personal information and use/disclose it appropriately.

Practically, that means thinking about:

• What customer data the agent can access
• Where that data is stored (e.g. personal spreadsheets vs your CRM)
• What happens to data when the contract ends (return, deletion, continued access)

If you collect customer information online or through forms, having a clear Privacy Policy is usually part of good hygiene-especially where leads are a key business asset.

Contractor vs Employee Risk

If the “agent” works like an employee (set hours, high control, integrated into the business, unable to work for others), there can be risk that they’re actually an employee in substance.

This matters because employees have statutory rights and entitlements that contractors don’t.

If you’re not sure whether your salesperson should be a contractor or employee, it’s worth getting advice early and using the right documents, such as an Employment Contract for employees or a properly drafted agency/contractor arrangement for contractors.

Common Mistakes Businesses Make (And How To Avoid Them)

Sales agency relationships often start with excitement-new markets, more revenue, more customers. But the legal and practical risks tend to show up later, especially once money is on the table.

Here are some common pitfalls we recommend avoiding.

1. Not Defining “A Sale” Clearly

Does commission apply when a customer signs? When you invoice? When you’re paid? What if the customer pays late, partially pays, or disputes the invoice?

If you don’t define this clearly, you may end up paying commission on revenue you never receive.

2. Paying Commission On “Introductions” Without A Process

Sometimes an agent claims commission just because they emailed an introduction-even if you did all the work afterwards.

A common solution is to define what counts as a valid introduction, and require the agent to log it (with evidence) in a CRM or email trail within a set time.

3. Granting Exclusivity Too Early

Exclusivity can be valuable for a motivated agent-but it can also block your growth if the agent underperforms.

If you do grant exclusivity, protect yourself by including:

• Minimum sales targets
• Reporting obligations
• Clear review points
• A right to remove exclusivity (or terminate) if targets aren’t met

4. Letting The Agent Use Their Own Terms Or Contract Templates

If your agent is negotiating your deals, you should stay in control of the legal terms your customers accept.

Otherwise, you could end up with inconsistent promises, discounting commitments, or liability terms you didn’t approve. Having a consistent contract framework (for example, customer terms or a master services setup) makes agency sales much easier to manage.

5. Using Generic Templates That Don’t Match Your Business Model

Sales commission structures and lead ownership rules are highly business-specific. A one-size-fits-all template can miss the exact thing you end up fighting about later.

If your sales are complex (long sales cycles, recurring revenue, renewals, upsells, channel partnerships), it’s worth getting the agreement tailored-because the cost of getting it wrong is usually higher than the cost of doing it properly from day one.

Key Takeaways

• A Sales Agency Agreement sets the ground rules when someone sells your goods or services on your behalf, usually for commission.
• The most important clauses typically cover the agent’s authority, territory and exclusivity, commission calculation and triggers, customer ownership, confidentiality, and termination.
• Commission disputes are common, so it’s critical to define what counts as a “sale”, when commission is earned, and what happens with refunds, cancellations, and post-termination deals.
• If the agent collects or accesses customer data, you should consider Privacy Act 2020 compliance and ensure your business has appropriate privacy practices in place.
• Misleading sales claims can create serious risk under the Fair Trading Act 1986, so brand and marketing controls should be clearly set out.
• Sales agents are often contractors, but you should ensure the relationship is documented correctly to avoid contractor vs employee misclassification issues.
