Reseller Agreement vs Affiliate Agreement for UK SaaS

A channel partner can grow your SaaS business quickly, but the wrong model can create messy customer ownership, unpaid invoices and support obligations you never priced into the deal. Founders often call every partner an affiliate, let resellers use the product name without controls, or forget to say who actually contracts with the end customer.

The choice between a SaaS reseller agreement, an affiliate agreement and a referral arrangement affects your revenue model, customer terms, data protection position, brand risk and liability if something goes wrong. A reseller is usually closer to the sale and may contract directly with the customer. An affiliate or referral partner usually sends leads to you and earns a commission.

For a UK software company building channel partnerships, the right structure depends on how much control you want over pricing, customer relationships, onboarding and renewals.

Choosing the Right Channel Model for Your SaaS

The best channel model is the one that matches who sells, who signs the customer, who gets paid and who carries the customer relationship after the sale.

In practice, software companies often use three related but different models:

• Reseller model: the partner buys, sublicenses or resells access to your SaaS to end customers under reseller terms, often under a software reseller contract. The reseller may set the customer price, invoice the customer and provide first-line support.
• Affiliate model: the partner promotes your SaaS using approved affiliate marketing methods and receives commission for eligible sign-ups, trials or paid subscriptions. The customer usually contracts directly with your company.
• Referral model: the partner introduces a lead or opportunity to you, often through a warm introduction or lead registration process. You handle the sales process and contract with the customer if the opportunity converts.

The distinction matters because each model allocates commercial control differently. A reseller may feel like a distribution partner and can become the face of your product in a market, sector or territory. An affiliate is usually a marketing channel. A referral partner is often a relationship source, such as an accountant, consultant, agency, implementation partner or industry adviser.

For example, a cybersecurity SaaS startup might appoint an IT services business as a reseller for SME clients. That partner could bundle the SaaS with its managed services, invoice the client monthly and provide onboarding. The SaaS provider would need a reseller agreement that controls sublicensing, support standards, brand use, data handling and customer communications.

In contrast, a project management SaaS company might appoint a business coach as an affiliate. The coach posts approved content, shares a tracking code and earns a commission when subscribers join through that code. The SaaS company keeps direct control over the customer contract, subscription terms and account support.

A referral partner sits between these examples. A consultant may introduce a qualified enterprise lead to your sales team, then step back while you negotiate the SaaS contract. The partner earns a referral fee if the customer signs within an agreed period.

A practical decision checklist is:

• Customer relationship: do you want the partner or your company to be the customer-facing contracting party?
• Pricing: will the partner set its own resale margin, or will you keep fixed subscription pricing?
• Sales effort: is the partner closing deals, publishing promotions or making introductions?
• Support: will the partner provide first-line support, or will all customers contact your team?
• Data access: will the partner access personal data, customer usage data or admin dashboards?
• Brand control: will the partner use your trade marks, product name, screenshots or sales collateral?
• Liability exposure: could the partner make promises about uptime, security, integrations or ROI that bind you commercially?

If the partner is genuinely selling your product to its own clients, a SaaS reseller agreement in the UK will usually be more suitable than a light affiliate agreement. If the partner is only driving traffic or leads, an affiliate agreement or referral agreement is usually cleaner and safer.

Who Contracts With the Customer and Takes Payment

The single biggest difference between a reseller and an affiliate is usually who signs the customer contract and controls the payment flow.

In a reseller model, there are commonly two contracts. The first is between the SaaS provider and the reseller. The second is between the reseller and the end customer. Depending on how the arrangement is structured, the reseller may either purchase licences from the provider and resell them, or be authorised to grant access to the SaaS on agreed terms.

This creates a more layered commercial relationship. The customer may see the reseller as the supplier, especially where the reseller invoices the customer, provides onboarding and bundles your SaaS with its own services. Your software reseller contract then needs to make clear what rights the reseller has, what customer terms must be passed through and what the reseller must not promise.

In an affiliate agreement in the UK, the customer usually contracts directly with the SaaS provider. The affiliate sends traffic, leads or sign-ups through a code, tracking link or approved campaign, but does not sell the subscription itself. The provider takes payment from the customer and pays the affiliate commission if the sale meets the eligibility rules.

A referral partner is also usually outside the customer contract. The referrer introduces the opportunity, but the SaaS provider owns the sales process, signs the customer and collects payment. The key difference between reseller vs referral partner arrangements is how involved the partner is after the introduction. A reseller often stays involved. A referral partner may not.

Payment Flow Examples

Payment mechanics should be written in plain operational detail. Ambiguity here can lead to disputes about commission, refunds, churn, chargebacks and renewals.

Common structures include:

• Wholesale reseller pricing: the reseller pays the provider a discounted rate and resells to customers at its chosen price, subject to any pricing rules.
• Revenue share: the provider collects customer subscription fees and pays the reseller a percentage, often used where the provider wants to keep billing control.
• Affiliate commission: the provider pays a fixed amount or percentage when a tracked customer completes a qualifying action, such as becoming a paid subscriber.
• Referral fee: the provider pays a fee if a registered lead signs a contract within a specified attribution window.

Your agreement should explain when the partner earns money, when payment is due, what happens if a customer cancels, and whether commission applies to renewals, upgrades, add-ons or only the first payment. For SaaS products, renewal commission can be commercially sensitive because a partner may expect passive income long after doing the original work.

You should also decide whether VAT is added to partner invoices and how the parties will handle valid tax invoices or equivalent payment records. This is a commercial and accounting workflow issue, and businesses commonly align the drafting with their finance process and HMRC record-keeping expectations.

Customer Terms and Pass-Through Obligations

A reseller arrangement should prevent a gap between what the customer is promised and what the SaaS provider is prepared to deliver.

If the reseller contracts with customers, require the reseller to include core terms in its customer agreement. These might include acceptable use rules, licence restrictions, payment consequences, suspension rights, data processing requirements, intellectual property ownership, warranty limits and liability exclusions. This is often called a pass-through requirement.

For example, if your SaaS terms prohibit reverse engineering, credential sharing and unlawful content uploads, the reseller should not be free to omit those restrictions from its customer terms. If your uptime commitments are subject to planned maintenance and customer-side internet failures, the reseller should not promise 100 percent availability without exceptions.

Where you contract directly with customers through an affiliate or referral model, the partner agreement should say the partner has no authority to bind you, vary your terms or make commitments on your behalf. This is especially important if affiliates publish comparison content, discount offers, product claims or implementation promises.

If you sell to consumers as well as businesses, your customer-facing terms and sales process may need to account for the Consumer Rights Act 2015 and consumer cancellation rules. Many B2B SaaS companies are focused on business customers, but channel activity can blur the line if a partner markets more broadly than expected.

Support, Onboarding and Data Protection Responsibilities

Support and data protection should follow the real customer journey, not just the label used for the partner.

Resellers often create support risk because customers may not know where to go when something breaks. If the reseller promises support but escalates every ticket to you, your team can end up funding a service level you did not price. If the reseller handles support badly, your brand may take the damage even where the customer contract is technically with the reseller.

A SaaS reseller agreement should state whether the reseller provides first-line support, onboarding, training, configuration, implementation or account management. It should also describe escalation routes, response expectations, information the reseller must collect before escalating, and any support exclusions.

For instance, you might require the reseller to handle password resets, basic setup and user training, while your team handles platform bugs and infrastructure incidents. The agreement can require the reseller to keep staff trained, use approved support scripts and avoid changing product settings in ways that compromise security.

Affiliates and referral partners usually should not provide technical support unless separately authorised. Their role is typically promotional or introductory. If an affiliate starts advising customers on configuration, security settings or compliance outcomes, they may create risk for both parties.

Data Protection Under UK GDPR

Channel partnerships need a clear data map because personal data may move between the SaaS provider, partner and customer at different stages.

UK GDPR and the Data Protection Act 2018 require businesses to identify their roles and put suitable data protection terms in place. The labels are not chosen for convenience. They depend on who decides why and how personal data is processed.

In an affiliate arrangement, the affiliate may collect marketing analytics, click data or lead details and share them with the SaaS provider. The provider may then use that data to create accounts, send sales emails or manage subscriptions. Depending on the setup, the parties may be separate controllers, joint controllers for some activities, or one party may act as processor for limited tasks.

In a reseller arrangement, the reseller may process customer contact details, support tickets, admin user data and billing information. If the reseller accesses the SaaS environment to support customer accounts, the agreement should address access controls, confidentiality, incident reporting, deletion and audit cooperation.

If your SaaS processes personal data on behalf of customers, your customer contract will usually need data processing terms that meet UK GDPR requirements. Where a reseller sits between you and the end customer, you need to make sure those processor terms still flow through properly. Otherwise, the reseller might promise compliance terms that do not match how the platform actually works.

Practical data protection points to address include:

• what personal data the partner can collect and share;
• the lawful basis for marketing communications where relevant;
• whether the partner can upload customer data into the platform;
• who responds to data subject requests;
• how suspected personal data breaches are reported and escalated;
• whether international transfers are involved;
• how long lead, customer and usage data is retained after termination.

Marketing compliance also matters. If affiliates send promotional emails or SMS messages, the Privacy and Electronic Communications Regulations can be relevant alongside UK GDPR. Your agreement should prohibit spam, misleading promotions and use of purchased lists unless the campaign is legally compliant and specifically approved.

Onboarding and Implementation Promises

Implementation promises are a common source of disputes because the partner may sell a result that depends on customer systems, integrations or internal adoption.

Your reseller or referral documents should control what partners can say about setup time, integrations, migration support, service levels, security certifications and compatibility. If you provide a sales deck, product comparison sheet or implementation timeline, make clear whether it is approved collateral and whether it can be edited.

For more complex SaaS, consider certification or training requirements before a reseller can implement the product. This is especially useful for HR tech, fintech, healthtech, cybersecurity, AI tools or platforms that rely on API integrations. A partner who misunderstands the product can create support tickets, customer churn and reputational harm.

Liability, Brand Control and Commercial Terms to Lock Down

A good channel partner agreement gives the partner enough freedom to sell while stopping them from exposing your business to uncontrolled liability.

Resellers, affiliates and referral partners all interact with your reputation. A partner may use your name in ads, make claims about your product, publish discounts, compare competitors or speak to customers as though they represent your company. Without clear rules, it can be hard to stop poor conduct quickly.

Your agreement should define permitted use of trade marks, logos, product names, screenshots and marketing materials. In the UK, trade mark rights are commonly registered through the UK Intellectual Property Office, but unregistered brand reputation can also matter. The agreement should state that the partner receives a limited, revocable right to use approved brand materials only for the partnership.

For reseller arrangements, brand control may need to be more detailed. If the reseller is allowed to present itself as an authorised reseller, specify the exact wording, approval process and restrictions. If the reseller operates in a regulated or sensitive industry, check whether its marketing claims could create compliance issues for your product.

Authority and Misrepresentation

Partners should not have authority to make promises, warranties or statements on your behalf unless you have expressly allowed it.

This point is crucial for affiliate and referral models. The agreement should say the partner is independent, cannot bind your company, cannot vary your customer terms and cannot represent that it is your agent, employee or legal representative. For resellers, the position may be more nuanced, but you still need boundaries around statements made to customers.

Common risky statements include:

• guaranteeing a business outcome, such as revenue growth or complete compliance;
• promising integrations that are not supported;
• offering discounts or lifetime pricing without approval;
• describing security features inaccurately;
• claiming the product is certified, accredited or endorsed where it is not;
• promising bespoke development as part of the standard subscription.

The agreement can require partners to comply with your brand guidelines, marketing rules and approval process. It can also allow you to demand takedown of unauthorised content and suspend commission or reseller rights for serious breaches.

Liability Caps, Indemnities and Insurance

Liability terms should reflect the risk each party controls, rather than using the same wording for every channel model.

In a reseller agreement, the reseller may be responsible for its customer contracts, billing, local support, marketing claims and unauthorised modifications. The SaaS provider may be responsible for providing the platform in line with agreed service commitments. Both parties may need indemnities for misuse of intellectual property, data protection breaches, confidentiality breaches and unauthorised promises.

In an affiliate agreement, liability often focuses on promotional conduct. You may want indemnities for misleading advertising, unlawful email marketing, trade mark misuse, false claims, cookie or tracking non-compliance, and breach of platform rules. The affiliate will usually want clarity that it is not liable for product performance or customer support after a valid sign-up.

In a referral agreement, the liability profile is usually lighter, but not zero. A referrer may mishandle confidential information, introduce conflicts of interest, exaggerate product capabilities or claim fees for leads it did not genuinely originate.

Insurance requirements can also vary. A strategic reseller providing implementation services may need professional indemnity or cyber insurance. A small affiliate posting approved content may not. If you require insurance, make the type of cover and evidence process realistic for the partner category.

Territory, Exclusivity and Targets

Exclusivity should be earned through clear performance obligations, not granted casually because a partner is enthusiastic.

Resellers may ask for exclusive rights in a sector, customer type or country. That can be valuable where the reseller has market access, but it can also block your growth if the partner underperforms. If you grant exclusivity, consider sales targets, minimum revenue, lead activity, reporting obligations and a right to convert exclusivity to non-exclusive status if targets are missed.

Affiliates and referral partners are less likely to need exclusivity. If they do ask for it, be careful. A broad exclusive referral right could prevent you from working with other agencies, consultants or introducers in the same market.

Termination rights should be practical. You may need immediate termination for brand misuse, data breaches, unlawful marketing, non-payment, confidentiality breaches or conduct that harms your reputation. You should also state what happens after termination, including removal of logos, return or deletion of confidential information, access cut-off, final commission payments and treatment of existing customer accounts.

FAQs

Is a Reseller the Same as an Affiliate?

No. A reseller usually sells or sublicenses your SaaS to customers and may invoice or support them. An affiliate usually promotes your SaaS and earns commission when customers sign up directly with you.

What Is the Difference Between a Reseller and a Referral Partner?

A reseller is usually involved in the sale and sometimes the ongoing customer relationship. A referral partner normally introduces a lead, then your team manages the sales process, customer contract and support.

Do UK SaaS Companies Need Different Agreements for Each Partner Type?

Usually, yes. A SaaS reseller agreement, affiliate agreement and referral agreement allocate payment, liability, support, brand use and data responsibilities differently. Using one template for every partner can leave gaps.

Can a Reseller Change My SaaS Terms for Customers?

Only if you allow it. Your reseller agreement should state which customer terms must be used or passed through, and should prohibit unauthorised promises about pricing, uptime, support, security or product features.

Who Is Responsible for Data Protection in a Channel Partnership?

Responsibility depends on who collects, uses and decides how personal data is handled. UK GDPR and the Data Protection Act 2018 require the parties to define their roles and use suitable data protection terms.

Key Takeaways

• A reseller agreement is usually right where the partner sells, invoices, supports or manages customers more directly.
