02. Custom Marketplace & E-Commerce Platform

Agora

Agora is a headless commerce platform we design and build around how your business actually works: multi-vendor payments, a proper vendor app, courier-integrated logistics and tax compliance. It's a real platform, not a templated shopping cart forced to fit.

You own the code, the data and the roadmap. No cut per sale, no feature locked behind an enterprise tier.

Agora — Custom Marketplace & E-Commerce Platform
What it is

Custom multi-vendor marketplaces and e-shops, built to fit.

Off-the-shelf platforms work well until your model doesn't match their assumptions, and a marketplace almost never matches them. As soon as you need to split payments across vendors, give sellers a real mobile app, automate tax for your country, or design a checkout around your own categories, you hit the limits of the templated world and start fighting the tool.

Agora is how we build past those limits. It's headless and API-first: one solid commerce core, used by a public storefront, a vendor mobile app and an operations back-office. You can redesign any one of those, or add a new sales channel, without touching the engine underneath.

How it works

Four chapters, one coherent system.

Each chapter stacks on the last — same as the work itself. Scroll through to see how the pieces fit together.

  • 01 / 04Discover

    We map your business model before any code.

    Marketplaces live or die on the details — commission structure, payout schedules, who approves what, how tax works in your market. We map your operational reality first, so the platform is shaped around how your business actually runs.

    Discovery
  • 02 / 04Design

    Custom UI/UX for your customers and your sellers.

    A storefront built for discovery, trust and conversion, and a vendor experience that is a first-class product in its own right — not a cut-down admin account. Designed for your brand, not retrofitted from a template.

    Design
  • 03 / 04Build

    A headless core that handles the hard parts.

    Multi-vendor payment splitting, automated per-vendor payouts, courier-integrated logistics and statutory tax compliance — the genuinely difficult parts of a marketplace — built production-grade from day one, with testing and observability built in, not bolted on.

    Engineering
  • 04 / 04Own

    You leave with the keys, not a dependency.

    You get the codebase, the documentation and the ability to run it yourself. We ship in small steps so you're using working software early, and we keep payments, logistics and tax behind clean boundaries, so a new market or provider doesn't mean rebuilding.

    Ownership
What's inside

Everything it does, end to end.

Consumer storefront

Built for discovery, trust and conversion.

A server-rendered storefront tuned for speed and SEO, designed around your categories rather than a generic grid.

  • 01Curated, editable home experience — featured vendors, collections, banners
  • 02Rich filtering, sorting and fast, typo-tolerant search
  • 03Product pages with galleries, variants, stock awareness and vendor context
  • 04Guest checkout by default, with optional one-tap and passwordless sign-in
  • 05A single basket that correctly spans multiple independent vendors
  • 06Multiple payment methods and clear, locker/pickup-aware delivery options
Vendor experience

A real seller app, not a cut-down login.

Sellers get a dedicated mobile experience where catalogue, orders and earnings are a first-class product — the place custom builds pull decisively ahead of templates.

  • 01Guided onboarding with a clear draft → review → approved path
  • 02Full catalogue management from the phone, with rich storytelling
  • 03A live order dashboard with honest, after-commission earnings shown up front
  • 04One-tap courier voucher generation and parcel hand-off
  • 05Multi-member vendor teams with the right notifications to the right people
  • 06Transparent, itemised payout status on every order
Operations & payments

Where the business is actually run.

An operations back-office and a financial core built with the most rigour, because a marketplace that handles money has to be observable and trustworthy.

  • 01Marketplace payment splitting with automated per-vendor payouts and commission
  • 02Full and partial refunds — including correctly reversing one vendor's share
  • 03A live money-flow view of every order, explained in plain language
  • 04Automated statutory e-invoicing wired into the order lifecycle
  • 05Self-healing recovery and reconciliation for payment and fulfilment edge cases
  • 06Editable storefront content and merchandising — no developer required
Foundations

Boring, proven technology — on purpose.

We build on modern, mainstream, well-supported foundations so your platform is maintainable by any competent team and still supported in five years.

  • 01Headless, API-first core exposing both REST and GraphQL
  • 02One mobile codebase for iOS, Android and mobile web
  • 03Full bilingual support, architected for more languages with no rewrite
  • 04Provider-abstraction for payments, logistics, tax and email — swappable per market
  • 05SEO-ready, server-rendered pages with structured data and clean URLs
  • 06Centralised observability, privacy-respecting telemetry and continuous deployment

Frequently asked

The questions teams ask first.

Why build a custom marketplace instead of using Shopify or Sharetribe?

Off-the-shelf and templated platforms are excellent until your model doesn't fit their assumptions — and multi-vendor marketplaces rarely do. The moment you need per-vendor payment splitting, a real vendor app, or country-specific tax automation, you fight the tool. Agora is built around your model instead, and you own the result outright — no per-transaction platform tax.

Can Agora handle multi-vendor payments and automated payouts?

Yes. A single customer payment is split across multiple independent vendors, each paid their share automatically, with the platform retaining commission and any service fees. Commission is computed server-side per order, and refunds — including reversing an individual vendor's share on a multi-vendor order — keep money, stock and tax records consistent.

Do sellers get a mobile app?

Yes — a dedicated vendor app is core to the platform, not an afterthought. Sellers onboard, manage their catalogue, accept orders, generate courier vouchers and track earnings from their phone, with honest after-commission figures shown up front. It is a first-class product, not a cut-down admin login.

Does it handle tax, invoicing and regulatory compliance?

Yes. Statutory e-invoicing is wired directly into the order lifecycle, with correct handling of consumer receipts, business-to-business commission invoices and credit notes on refunds. The compliance layer is designed to be swappable per jurisdiction, so the same architecture can target a different market without reworking the commerce core.

Do we own the code, or are we locked in?

You own it. You leave with the codebase, the documentation and the ability to run it — no per-transaction platform tax, no feature held hostage behind an enterprise tier, no plugin that breaks on the next update. We favour provider-abstraction over lock-in so payments, logistics and tax can adapt without structural surgery.

How much does it cost to build a custom multi-vendor marketplace?

It depends on scope — the number of vendor and operations workflows, payment and tax complexity, and how many surfaces (storefront, vendor app, back-office) you need. As industry context, a focused marketplace MVP is typically a mid-five-figure investment, while a full, production-grade multi-vendor build with a vendor app, logistics and compliance runs higher. We don't quote from a price list — we scope it against your model in a discovery call so the number reflects what you actually need.

How long does it take to build a marketplace?

A focused, launchable MVP is usually a matter of a few months; a full multi-vendor build with a vendor app, courier logistics and tax compliance takes longer. We deliver iteratively — working software early and often — so you see and use real functionality well before the full platform is complete, rather than waiting for a big-bang reveal.

What's the difference between a headless and a traditional marketplace platform?

A traditional platform couples the storefront to the commerce engine, so changing the look or adding a channel means fighting the core. Agora is headless and API-first — the commerce engine is separate from the front-ends that consume it, so you can reinvent the storefront, add a kiosk or a B2B portal, or launch a new channel against the same trustworthy core without rebuilding it.

What else can you build on the same platform besides a marketplace?

The same capability powers single-brand e-shops, B2B ordering portals with account-based pricing, subscription and recurring-commerce models, and region-specific commerce with local payment rails and tax compliance built in — each shaped around your brand and market, with you owning the result.
