B2B Marketplace Development Services for Scalable Trade, Wholesale and Multi-Vendor Platforms

We provide B2B marketplace development services for wholesale, trade, supply, procurement and cross-border commerce platforms. We build the buyer storefront, supplier onboarding, product catalogue, marketplace payments, admin dashboard, KYC workflows, credit logic and operator tools needed to run a scalable B2B marketplace. We don't stop at the storefront like the others do.

The argument

Real B2B marketplaces are 60% trust infrastructure and 40% UI. Anyone who pitches the inverse hasn't shipped one.

What you get

Eight capabilities, shipped together.

You don't pick from a menu. A marketplace needs the storefront, the trust layer, and the operator tooling moving in lockstep, otherwise it never reaches the unit economics that justified building it.

Catalogue ingestion and normalisation

CSV, Shopify exports, manual entry, partner APIs, pulled into one model with dedupe, enrichment, and search-relevance built in. Scales past 1M SKUs.

KYC and identity orchestration

Multi-provider KYC routing, document verification, business-entity checks, AML and sanctions screening. The trust layer most agencies don't build.

Net-terms and credit engine

90-day net terms (a la CREOATE Trade Direct). Credit scoring, exposure limits, dunning, collections, reconciliation, the math that keeps default rates under 3%.

Marketplace payments and payouts

Stripe Connect-style splits, commission engines, multi-currency settlement, payout reconciliation, dispute and chargeback handling.

Cross-border logistics and duty

Carrier callbacks, customs documentation, duty and VAT calculation, returns routing. The infrastructure that lets a UK marketplace ship into the EU and US cleanly.

Fraud, anti-counterfeit, supplier vetting

Behavioural fraud signals, listing-content scanners, supplier onboarding checks, brand-protection workflows.

Storefront and buyer UX

Next.js storefront, embedding-relevance search (Algolia or Elastic tier), marketing subdomain on WordPress. The 10% above the waterline.

Operator tooling

The admin console the marketplace actually runs on: supplier desk, dispute queue, payout review, KYC overrides, fraud triage.

The marketplace iceberg

What buyers see vs. what marketplaces actually are.

Roughly 60% of engineering investment on a serious marketplace goes into KYC, risk, fraud, payments, and credit. Storefront is the visible 10%.

If a quote pretends otherwise, the marketplace will eventually rebuild it. Better to build it correctly the first time.

Good fit if

When a marketplace is real engineering

Founders building cross-border B2B wholesale, trade, or supply marketplaces
Operators bolting net terms, BNPL, or credit onto an existing storefront
Marketplaces past the prototype stage that need real KYC, AML, and dispute infrastructure
Teams replacing a multi-vendor WooCommerce or Magento setup that can't carry the trust layer

Probably not a fit

We'll be honest if a marketplace is the wrong call

Pure single-vendor e-commerce, where a Shopify Plus build is faster and cheaper
Marketplaces with no payments, escrow, or trust requirement, many MVPs
Teams looking for the cheapest possible vendor instead of a partner who'll argue with the roadmap

Evidence, CREOATE

B2B Marketplace Development Case Study: CREOATE

Catalogue at scale

6,500 brands averaging ~150 SKUs each, in CSV, Shopify exports, manual entry, and partner APIs. Ingestion, normalisation, dedupe and relevance is where the months of engineering go. Storage is trivial; the messy upstream formats are the hard part.

Net terms, Trade Direct

90-day net terms is CREOATE's wedge against Faire and Ankorstore. Credit scoring, dunning, collections, reconciliation sit underneath the BNPL promise. Default rate above 3 to 4% breaks the marketplace, so the credit engine is the unit economics.

Data layer on DynamoDB

Primary store is DynamoDB on AWS eu-west-2, single-table design with GSIs sized to the marketplace access patterns. Catalogue, orders, KYC state, payout queues, all there. Search relevance lives on an Elastic or Algolia tier alongside.

Long-form on the CREOATE case study. Adjacent infrastructure for Khatabook and other transactional platforms. API and integration work is where most of the trust-layer engineering lives.

How we work

How Our B2B Marketplace Development Process Works

Three to four weeks of paid discovery first. We map the trust layer, the credit model, the catalogue shape, the operator workflows. You walk out with a system design and a phased plan whether or not you continue with us.

Build is phased and runs against working software, not Gantt charts. Storefront and operator tooling first. Trust layer, payments, and credit alongside. Two-week sprints, demo at the end of each, code in your repos.

We don't disappear at launch. The marketplace will need credit-engine tuning, fraud rule iteration, and supplier-onboarding adjustments for the first year. That's where we earn the long retainer.

“The homepage looks like e-commerce. The codebase is fintech with a storefront bolted on. Anyone selling you the inverse has never shipped one.”
Ritesh, Founder, Appycodes

If you're building one

Bring the credit and KYC question. We'll know within a call whether the rest is worth talking about.
