What Payment Structure Do I Use For My Online Marketplace? (2026 Updated)

Running an online marketplace can be an exciting way to build a scalable business - you connect buyers and sellers, provide trust and convenience, and (ideally) collect a margin along the way.

But one of the first “make or break” decisions is also one of the most practical: how should money actually move through your marketplace? In other words, what payment structure do you use, and how do you charge for it?

This (2026 updated) guide walks you through the most common online marketplace payment models in New Zealand, what each one means legally, and what you should lock down in your contracts and website terms so you’re protected from day one.

What Payment Structures Work Best For Online Marketplaces?

There’s no single “best” payment structure for every marketplace. The right model depends on what you’re selling (products vs services), how involved you are in fulfilment, what level of trust you need to build, and how you want revenue to scale.

Most marketplaces use one (or a combination) of the payment structures below.

1) Commission Per Transaction (Percentage Or Fixed Fee)

This is the classic marketplace model: a seller makes a sale, and you take a cut.

• Percentage commission (e.g. 10% of the sale price) scales naturally as sales grow.
• Fixed fee (e.g. $2 per transaction) is simple and predictable, but can be harsh on low-value items and too cheap for high-value items.

When it works well: product marketplaces, digital goods marketplaces, and service marketplaces where you’re driving demand and trust.

Legal tip: Commission sounds straightforward, but the “base” matters. Is your commission calculated on:

• the item price only, or item price + shipping?
• amount paid by the buyer inclusive of GST?
• amount after refunds, discounts, coupons, chargebacks?

If your wording is unclear, you can end up in disputes with sellers (especially when you start scaling).

2) Listing Fees (Pay To List)

A listing fee charges sellers to post an item or create a listing (whether it sells or not). This can be:

• a one-off fee per listing
• a fee after a certain number of free listings
• a fee for “premium” visibility (featured placement, boosted listings, etc.)

When it works well: marketplaces with strong buyer demand, or where sellers gain significant marketing value just by being listed.

Watch out: listing fees can increase seller churn if sales aren’t consistent. They also raise consumer law style concerns (fairness and transparency) if you’re advertising “free to sell” but the fine print makes selling realistically impossible without paid boosts.

3) Subscription Memberships (Monthly/Annual Seller Plans)

Subscriptions (e.g. $39/month for a seller account) can give you stable revenue and reduce reliance on individual transaction volume.

Common subscription variations include:

• tiered plans (basic/pro/enterprise)
• freemium models (free plan with limitations, paid plan with better tools)
• subscription + lower commission (hybrid model)

When it works well: service marketplaces (where sellers use your platform as an ongoing lead generation channel), or marketplaces offering software-like tools (analytics, booking calendars, inventory management).

Legal tip: if you’re offering an ongoing platform service, it often makes sense to clarify availability expectations, support timeframes, and maintenance windows in something like a Service Level Agreement (even if it’s light-touch and written in plain English).

4) Buyer Fees (Service Fees, Booking Fees, Protection Fees)

Some marketplaces add a fee to the buyer at checkout (sometimes framed as a service fee or booking fee). This can help fund:

• payment processing
• fraud protection
• dispute handling
• customer support

When it works well: booking-style marketplaces and “trusted” marketplaces where your platform is doing meaningful work to reduce risk.

Legal tip: buyer fees must be clearly disclosed. In New Zealand, pricing and representations are heavily influenced by the Fair Trading Act 1986 - which, in plain terms, means you need to avoid misleading pricing and surprise add-ons at checkout.

5) Payment Processing Fees (Pass-Through Or Mark-Up)

You can either:

• absorb payment processing fees (simpler user experience), or
• pass them on (either to the seller, the buyer, or both), or
• build them into your commission (a blended approach).

Watch out: if you “mark up” processing fees, describe it accurately. Calling something a “processing fee” when it’s actually part-margin can create complaints and reputational risk (and potentially misleading conduct issues).

6) Escrow/Hold-and-Release Payments

Some marketplaces hold buyer funds and release them when a milestone is met (e.g. delivery confirmed, service completed).

This can build trust - but it also increases your operational and legal complexity.

Common examples:

• service marketplaces (release on completion)
• high-value goods marketplaces (release on buyer confirmation)
• custom-made product marketplaces (release in stages)

Legal tip: holding money can change your risk profile significantly. You’ll want very clear rules around dispute windows, evidence requirements, partial refunds, and what happens if a party doesn’t respond.

Do I Take Payments As The Platform Or Do Sellers Get Paid Directly?

This is the key structural decision most marketplace founders don’t fully appreciate at the start.

At a practical level, you’re choosing between:

• Seller-direct payments: the buyer pays the seller (you invoice the seller for fees, or deduct via a separate method).
• Platform-managed payments: the buyer pays via your platform, and you later pay out to the seller (often called “split payments” or “managed payments”).

Both can work - but the legal and compliance implications are different.

Option A: Seller-Direct Payments (You Don’t Touch The Funds)

With seller-direct payments, your marketplace is more like a matching service. The seller is typically the merchant, and you earn revenue through invoices, subscriptions, or lead fees.

Pros:

• lower operational burden (less reconciliation, fewer payouts)
• you may reduce chargeback/refund handling complexity
• often easier from a “who is responsible?” perspective

Cons:

• harder to enforce commission (you’re relying on reporting or separate billing)
• less control over the checkout experience
• more risk of “off-platform” payments (sellers bypass you)

What you must make clear: that the sale contract is between buyer and seller, and your marketplace is an intermediary (while still being careful not to overstate this if you’re heavily controlling the transaction).

Option B: Platform-Managed Payments (You Collect, Then Pay Out)

Here, the buyer pays through your platform checkout, and you distribute funds to sellers after taking your fees. This is common because it creates a smooth experience and makes monetisation easier.

Pros:

• better user experience and trust
• commission is automatic
• better dispute handling tools (refunds, partial refunds, holds)

Cons:

• higher admin and compliance complexity
• greater exposure to refunds, chargebacks, fraud and complaints
• you need robust terms and processes (and you can’t just “wing it”)

Merchant of record matters: Even if you use Stripe Connect, PayPal for Platforms, or another split-payment provider, you still need to decide (and document) who is treated as the merchant of record. That affects tax invoicing, consumer claims, and how disputes play out.

If you’re not sure which model you’re effectively operating, it’s worth getting advice early - because changing payment architecture later can be painful (and you’ll often need to update your terms, pricing, onboarding, and tax setup).

A Quick Reality Check: Your “Legal Role” Depends On Your Actual Behaviour

Founders sometimes assume they can simply write “we’re just a platform” in their terms and avoid responsibility.

In practice, if you:

• control the checkout and payment flow
• set mandatory pricing rules
• control fulfilment or delivery terms
• handle refunds as the primary contact
• make strong promises about product quality, delivery timeframes, or “guaranteed” outcomes

…then you may be taking on more responsibility than you realise, regardless of what your terms say. That’s why aligning your payment structure, platform design, and legal documents is so important.

What Laws Affect Marketplace Payment Structures In New Zealand?

Payment structure isn’t just a pricing question - it touches multiple legal areas. Here are the most common ones that affect online marketplaces in NZ.

Consumer Law: Pricing, Refunds, And Customer Expectations

Even if your sellers are separate businesses, your platform’s user experience can create expectations that “the marketplace” is responsible.

Two key laws are usually in play:

• Fair Trading Act 1986 (FTA): you must not mislead people about prices, fees, availability, delivery, “buyer protection”, or who they’re contracting with.
• Consumer Guarantees Act 1993 (CGA): consumer rights around quality and remedies often apply when goods/services are supplied to consumers in trade. Depending on your structure, either the seller, the platform, or both could end up dealing with the practical fallout.

From a payments point of view, you should be able to answer clearly:

• Who processes refunds - the seller, the platform, or both?
• When can a buyer request a refund?
• What happens if there’s a chargeback?
• Can your fees be refunded, or are they non-refundable?

The more transparent you are upfront, the fewer disputes you’ll be managing later.

Privacy And Data Security (Especially At Checkout)

Marketplaces collect a lot of personal information: names, addresses, email addresses, order history, and sometimes identity verification data. If you’re facilitating payments, you’re also handling sensitive transactional data (even if a payment provider processes card details).

Under the Privacy Act 2020, you need to take reasonable steps to protect personal information and be transparent about what you collect and why.

Most marketplaces need a Privacy Policy, and if you use tracking technologies for marketing and analytics, a Cookie Policy is often part of a clean setup too.

Tax (Including GST): Who Is Supplying What?

Your payment structure affects your tax setup, especially GST. For example:

• If you charge commission, you may be making a taxable supply of services to the seller.
• If you charge buyer fees, you may be making a taxable supply to the buyer.
• If you are treated as the supplier/merchant of record, you may need to account for GST on the full sale amount (not just your cut), depending on how the arrangement is structured.

GST can get complicated quickly in multi-party marketplaces (and even more so if sellers or buyers are overseas). It’s worth speaking to an accountant early - and aligning that advice with your legal documents so your contracts reflect the intended tax position.

Chargebacks, Fraud, And “Who Wears The Loss?”

Chargebacks are part of online commerce. Your terms should clearly set out:

• how chargebacks are handled
• whether you can deduct chargeback amounts from seller payouts
• your right to suspend accounts where fraud is suspected
• what evidence sellers must provide to dispute chargebacks

This is also where having clear platform rules helps. For example, your user terms can be supported by an Acceptable Use Policy if you want to set behavioural standards (fraud, abuse, circumvention, harassment, etc.).

How Do I Choose The Right Payment Model For My Marketplace?

If you’re feeling a bit stuck, don’t stress - you don’t need to guess. A good approach is to work backwards from the “risk points” in your marketplace and choose a payment model that supports them.

Step 1: Work Out What You’re Really Selling

Ask yourself:

• Are you selling access to sellers (lead generation)?
• Are you selling a trusted transaction environment (checkout + dispute support)?
• Are you selling a software platform (tools + subscriptions)?

Your payment structure should match the value you provide. If you only introduce buyers and sellers, seller-direct payments plus subscription/lead fees might fit. If you’re building trust and handling disputes, platform-managed payments and transaction fees often make more sense.

Step 2: Decide How Much Control You Need Over The Buyer Experience

If your brand promise depends on consistency (fast shipping standards, verified providers, “buyer protection”), you’ll likely need more control over payment and dispute processes - which pushes you toward managed payments.

If you want a lightweight model (directory-style), seller-direct payments can be simpler, as long as you manage “off-platform” leakage.

Step 3: Think About Seller Incentives (And Bad Behaviour)

Your pricing affects seller behaviour:

• High commission can drive sellers to move customers off-platform.
• High listing fees can reduce low-quality listings, but may discourage new sellers.
• Subscriptions can attract professional sellers, but may deter casual sellers.
• Buyer fees can reduce conversion rates if not clearly justified.

A lot of marketplace “legal problems” start as incentive problems - so your payment structure is part of your risk management, not just your revenue plan.

Step 4: Make Sure Your Payment Terms Match Your Tech Stack

Your contracts should reflect what your platform can actually do. For example:

• If your payment provider can’t do partial refunds, don’t promise partial refunds “anytime”.
• If payouts are weekly, don’t imply sellers get paid instantly.
• If you reserve the right to hold funds, your platform should have an operational process to review disputes promptly.

Misalignment here is where complaints and chargebacks snowball.

What Legal Documents Should Support My Marketplace Payment Structure?

Your payment structure becomes enforceable (and scalable) when it’s properly documented. For most NZ marketplaces, that usually means having clear buyer-facing terms, seller-facing terms, and supporting privacy disclosures.

Marketplace Terms: Your Core Rulebook

Your public-facing terms set expectations for users and help manage disputes. Depending on your model, this may include marketplace-specific clauses around fees, refunds, disputes, chargebacks, and account suspensions.

Many platforms use purpose-built Marketplace Terms and Conditions so the document actually matches how marketplaces operate (rather than generic online shop terms).

E-Commerce Terms (If You’re Running A Traditional Checkout Too)

Some marketplaces operate a hybrid model - for example, you sell your own products as well as hosting third-party sellers, or you run a marketplace for goods with a standard retail checkout flow.

In those cases, it can be useful to have dedicated E-Commerce Terms and Conditions that cover ordering, shipping, returns, and payment processing clearly.

Website Terms Of Use (Especially For Browsing, Accounts, And Platform Rules)

Even before someone buys or sells, your platform needs rules for accounts, content, and site use. This is where you cover things like:

• account eligibility and registration
• user-generated content (including reviews and listing content)
• prohibited behaviour and enforcement
• intellectual property and use of your platform materials

This is often handled through Website Terms of Use, which can sit alongside your transaction-focused terms.

Refunds, Disputes, And Chargebacks: Put The Process In Writing

Marketplaces get into trouble when the process is “vibes-based” - you want clear timelines and rules, such as:

• time limit for buyers to lodge a dispute
• required evidence (photos, tracking, messages)
• how you decide disputes (and whether your decision is final)
• how you handle partial refunds, platform fees, and shipping costs
• chargeback cooperation requirements for sellers

The goal isn’t to be harsh - it’s to be predictable. Predictability is what reduces escalations.

Privacy Disclosures (Because Payments Always Mean Data)

When you run a checkout, you’re collecting and using personal information, and often sharing it between parties (e.g. giving the seller the buyer’s delivery details).

A good Privacy Policy should explain (in plain language):

• what you collect
• why you collect it
• who you share it with (including sellers and service providers)
• how long you keep it
• how users can request access/correction

If you use cookies for analytics or targeted advertising (which most marketplaces do), your Cookie Policy helps set expectations and supports privacy compliance.

Don’t DIY The “Important Bits”

Templates can be tempting, especially early on. But marketplaces are inherently multi-party - and that means more edge cases (disputes, fraud, partial fulfilment, delayed shipping, banned sellers, negative reviews, chargebacks).

It’s usually worth getting your terms drafted or reviewed so they reflect:

• your real payment flow
• your real operational processes
• the risks specific to your category (services vs goods, high value vs low value, regulated categories)

That upfront effort can save you a lot of time (and legal spend) later.

Key Takeaways

• The most common marketplace payment models include transaction commission, listing fees, subscriptions, buyer fees, and escrow/hold-and-release structures.
• Your biggest structural decision is whether sellers get paid directly or whether your platform manages payments and pays sellers out later - because that affects disputes, refunds, and overall legal risk.
• NZ marketplaces need to consider consumer law (especially the Fair Trading Act 1986 and Consumer Guarantees Act 1993), privacy obligations under the Privacy Act 2020, and practical issues like chargebacks and fraud.
• Your payment structure should align with what your marketplace actually does in practice, not just what you’d like to say in your terms.
• Strong legal foundations usually include clear Marketplace Terms, Website Terms of Use, and privacy documentation, with refund and dispute processes written in plain English.
• If you’re unsure who is responsible for payments, refunds, or GST in your model, getting tailored advice early can prevent expensive rework later.
