Question 1

How much does a multi-vendor marketplace cost?

Accepted Answer

From $8,000 to $40,000 USD, or A$12,000 to A$55,000. That range is wide because marketplaces differ enormously in scope. A single-category marketplace with manual vendor approval and simple commissions sits at the low end. Multi-category, multi-currency, automated payouts, logistics integration and dispute resolution belongs at the high end. Treat the low figure as a starting point for a focused launch, not a finished product.

Question 2

The cheap marketplace scripts I see online cost $99. Why not use those?

Accepted Answer

You can, and for a proof of concept it may be sensible. The problems appear when real money moves: commission calculation on partial refunds, vendor payouts across currencies, tax handling per jurisdiction, and the security work needed before you store thousands of payout bank details. Most of our marketplace work is fixing exactly these gaps in an off-the-shelf script. Starting from a script can save a month and cost three.

Question 3

How do vendors get paid?

Accepted Answer

Two common models. Platform-collect: buyers pay you, you hold funds, and pay vendors on a schedule after a hold period, which covers refunds and disputes. Direct-to-vendor: each vendor connects their own payment account and the platform takes commission at the transaction. Platform-collect gives buyers one checkout and gives you control, but it puts you in the middle of every dispute and may trigger money-transmission rules in some countries. That is a legal question worth asking before a technical one.

Question 4

How long does a marketplace take to build?

Accepted Answer

Four to nine months for something you can launch on. We build in stages: vendor onboarding and catalogue first, then orders and commission, then payouts, then the admin and dispute tooling. Launching with manual payouts and fifty approved vendors is a reasonable way to start. Trying to launch with a fully automated global payout system on day one is how marketplace projects run out of money.

Question 5

Is this a chicken-and-egg problem we should solve before building?

Accepted Answer

Yes, and it is worth being blunt about it. The software is the easy part. A marketplace with no vendors has nothing to sell, and one with no buyers gives vendors no reason to stay. Most successful launches start with a curated set of vendors you recruit personally and a buyer audience you already have. If you do not have either, spend three months on that first and come back. We would rather lose the project than build something nobody uses.

Question 6

Who owns the platform and the vendor data?

Accepted Answer

You own the platform, the code and the database outright. Vendor data is a shared responsibility: vendors own their product information, you control the platform, and your terms of service govern what you may do with it. We will help draft the technical parts of the vendor agreement, such as commission changes and data export rights, but a lawyer should review the contract itself.

Question 7

What does ongoing support look like?

Accepted Answer

Ninety days of defect support after launch, because the first three months is when edge cases surface: a vendor editing an order mid-fulfilment, a refund on a split cart, a payout run that fails on one account. After that we recommend a monthly retainer covering maintenance, dependency updates and a set number of hours for changes. Marketplace software is never really finished.
