Marketplace Commission System
Commission looks from outside like a single percentage, but it is really a rule engine. Margins that vary by category, a discounted rate for new sellers and a campaign-period exception all have to be able to live at once. This page explains how that engine works.

Why Can Commission Never Be a Single Rate?
A marketplace commission system may look from outside like a single percentage, but it is really a rule engine. In real life you cannot apply the same rate to every category: margins are thin in electronics and wide on handmade goods. You may want to offer a discounted rate for the first three months to attract new sellers. During a campaign you may need to lower the rate temporarily in certain categories. All of these have to be able to live at once.
What makes that possible is rule precedence. The system looks from the most general to the most specific: first the platform-wide default rate, then the category rule, then the agreement specific to that seller, and finally an exception defined on a single listing. The most specific rule wins. That way you can define an individual exception when you need one without having to manage thousands of sellers one by one.
The second matter is what the commission is calculated on. The product amount, the total including shipping, before the discount or after it? The answer changes your margin directly and is the most frequent source of disagreement between you and your sellers. In PazaryeriSoft the calculation base is defined explicitly, and which rule was applied is recorded on every order.
The Four Rule Levels and Which One Wins
The system looks from the most general to the most specific; the most specific rule applies. Using the listing level sparingly keeps the management overhead low.
| Criterion | Platform | Category | Seller | Listing |
|---|---|---|---|---|
| Precedence | Lowest | Overrides the platform rule | Overrides the category rule | Highest; overrides them all |
| Typical use | The platform default | Categories with different margins | Contracted sellers, promotional onboarding | An individual exception, a special agreement |
| How many records | 1 | As many as there are categories | The sellers you have agreements with | Rare; defined by hand |
| Date constraint | Permanent | A campaign period can be defined | Can be tied to the contract term | Short-lived |
| Management overhead | None | Low | Medium | High; should be used sparingly |
The Five Revenue Lines Beyond Commission
They are not mutually exclusive; most mature marketplaces run three or four at once.
Sales Commission
The most common line. A proportional or flat deduction from every completed order; taken automatically from within the payment flow.
Transaction Fee
A flat service charge per order. It covers the transaction cost that commission does not on low-value sales.
Seller Subscription Packages
Monthly or annual packages; usually sold bundled with listing allowances, a lower commission rate and promotion credits.
Listing Fees
A fee for every record published. In listing-based models it produces revenue even when nothing sells.
Premium and Featuring
Showcase, bump-to-top, badge and category priority packages. Sellers want them more once they see the performance screen.
Advertising and Sponsored Placements
Homepage banners, category sponsorship and sponsored listings in search results.
Defining the Rule and Applying It
On the left how commission is described, on the right how it works on an order. The link between them is built with transparency.
Defining the rule
- Proportional (%), a flat amount, or a combination of both
- Floor and ceiling: minimum and maximum commission amount
- Calculation base: product amount, total including shipping, before or after discount
- Tiered rates: commission falling as sales volume rises
- Date range: a temporary rate for a campaign period
- Currency and VAT-inclusive or exclusive treatment
Applying the rule
- Selecting the most specific rule in the order platform → category → seller → listing
- Recording which rule was applied on every order
- Deducting commission automatically within the split payment flow
- Setting commission off on refunds and partial refunds
- Letting the seller see the deduction breakdown in their own panel
- Holding rule changes in the audit trail
Modules That Come Ready in Commission Management
Multi-Level Rule Engine
Rules defined at platform, category, seller and listing level; the most specific applies and which one was in force is stored on the order.
Tiered (Volume-Based) Rates
The commission rate falls automatically once a monthly sales volume threshold is passed; a structure that encourages sellers to grow.
Date-Bound Campaign Rates
Temporary rates valid within a set date range. When the period ends the system reverts to the previous rule automatically.
Minimum and Maximum Limits
A floor on low-value orders and a ceiling on high-value ones. It keeps the margin under control at both extremes.
Deduction Breakdown and Transparency
The seller sees how much was deducted under which line on every order. Transparency removes most commission-related disputes.
Subscription and Package Management
Seller packages are defined; a package can carry listing allowances, a commission discount and promotion credits. Renewal runs automatically.
Selling Promotion Packages
Showcase, bump-to-top and badge packages are bought from the seller panel; they end automatically when the period expires.
Revenue Reports
A revenue breakdown by line: commission, transaction fees, subscriptions, promotions. It can be examined by category and by seller.
Scenario Comparison
The effect of a rate change on past sales can be examined in reports and seen before the decision is made.
