Custom B2B Commerce and E-commerce Engineering for Singapore

B2B portals, custom commerce platforms, and order management systems built for operators whose requirements have outgrown off-the-shelf software.

Solutions we build

Four categories of commerce software we deliver

Custom development across the commerce stack, anchored on B2B portal and order management work.

B2B portals & self-service commerce platforms

Custom B2B commerce platforms covering account-based purchasing, custom catalogs per buyer or tier, real-time inventory visibility, quotation and approval workflows, and reorder management. Built for operators whose B2B requirements have outgrown standard SaaS commerce platforms. This is our strongest commerce capability, with delivered experience in B2B portal work and adjacent distribution ERP projects.

Order management & fulfillment systems

Custom order management systems handling order capture across channels, inventory allocation, payment processing, fulfillment workflows, and integration with logistics partners. We build these as standalone systems or as modules within a broader commerce or ERP platform. This work draws on the same engineering patterns as our distribution and inventory systems, which makes order management a natural extension of our delivered capability.

Custom commerce platforms & storefronts

Custom-built commerce platforms for operators who need flexibility beyond standard SaaS commerce. Typical scope includes product catalog, checkout, account management, payment integration, and admin interfaces. We approach these as engineering projects, not platform implementations. For projects suited to Shopify, Magento, or Shopware, we recommend platform-certified agencies. Our work is for teams whose requirements have already exceeded those platforms.

Headless commerce & API-first architectures

API-first commerce backends supporting multiple frontends, including web, mobile apps, in-store kiosks, and partner integrations. Headless architecture is increasingly the right choice for commerce operators running complex omnichannel or B2B+B2C dual models. This is a capability we can deliver as a software engineering team, drawing on our broader API and integration practice. We are honest that headless commerce is an evolving area, not a deep specialty.

Who we serve

Three types of commerce teams we build for

Different commerce models, different software needs. Here is where we fit.

B2B distributors and wholesalers

These are operators selling to business buyers with complex pricing, account-based catalogs, and multi-location operations. They need self-service portals, custom pricing per buyer, ERP integration, and workflows for quotation and reorder. This is the buyer segment closest to our delivery experience, drawing on our B2B portal and order management work, including the multi-warehouse distribution ERP for auto parts referenced in our Logistics work.

Omnichannel retailers

These are retailers selling across online stores, marketplaces, and physical locations. They need unified inventory, order orchestration across channels, and consistent pricing or promotion management. We build for this segment using our custom commerce engineering and integration capabilities. For retailers needing a full omnichannel platform with extensive deployment history, specialist platform vendors may be a better fit.

D2C brands and online retailers

These are direct-to-consumer brands and digital-first retailers running custom storefronts. They need flexible product catalogs, custom checkout flows, and AI features for search and personalization. We approach this segment as custom engineering rather than platform implementation. For brands looking to launch on Shopify, Magento, or similar SaaS platforms, we recommend platform-certified agencies instead.

Where we can help

B2B commerce is where we have applied this engineering most

Most off-the-shelf commerce platforms are built for B2C first. B2B requirements often exceed what those platforms can deliver, and that is where custom engineering is most useful.

Bring us your scenario. Current systems, what you are trying to build, what is constraining you today, and timeline. The first call is a scoping conversation. We will tell you where we can help, where we are not the right fit, and what a realistic project looks like. No deck, no sales script.

AI adoption for commerce

Where AI is delivering measurable value in commerce today

Four AI use cases that have moved from experimental to standard practice in commerce operations.

01.

Product search and discovery

AI-powered search that understands intent rather than just keywords, supports semantic search across product catalogs, and adapts to typos and synonyms. Particularly valuable for large catalogs with thousands of SKUs. Well-scoped projects typically see a 15–30% improvement in search-to-purchase conversion.

02.

Personalization and recommendations

Recommendation engines for related products, frequently bought together suggestions, and personalized homepage layouts based on browsing and purchase history. These are well-proven AI use cases in commerce with measurable revenue impact. Realistic outcome: 5–15% increase in average order value through recommendation experiences.

03.

Fraud detection and order screening

Pattern detection on commerce orders to flag potential fraud, payment risk, and unusual buyer behavior. Built as a triage layer that reduces the workload on operations teams rather than as fully automated decision-making. Particularly useful for B2B commerce where unusual order patterns can indicate account compromise or pricing exploitation.

04.

Content automation for product catalogs

AI generation of product descriptions, image alt text, SEO metadata, and category page content. Useful for operators managing large catalogs where manual content work is a bottleneck. We build these with human review workflows because product content directly affects brand perception and compliance with marketplace policies.

Why Adamo APAC for commerce projects

Four reasons commerce teams choose us

What makes Adamo a strong fit for custom commerce engineering, specifically.

Custom engineering, not platform agency

We do not compete with Magento, Shopify, or Shopware agencies for standard storefront builds. We engineer custom commerce systems for operators whose requirements have moved beyond those platforms. If your B2B portal needs complex pricing, deep ERP integration, or custom order workflows beyond SaaS templates, that's where we work.

B2B commerce focus, not B2C generalist

Our delivered commerce experience is strongest in B2B portals, order management, and B2B+B2C dual platforms. The auto parts distribution ERP work referenced in our Logistics page is an adjacent project that demonstrates the same engineering patterns. For B2B operators, this focus matters more than a long list of B2C brand cases.

Singapore strategy, Vietnam engineering

Our Singapore office handles consultation, project coordination, and on-the-ground support. Engineering is delivered from Vietnam, where we have 170+ engineers across software and AI practices. You get APAC responsiveness, English-fluent tech leads, and scalable engineering for mid-market commerce teams - not just enterprise budgets.

Built-in AI capability

Adamo's AI services are a core practice across industries. If your commerce roadmap includes search, recommendations, personalization, or fraud detection, you get an engineering partner that has built and deployed AI systems in production. Not a commerce shop adding AI as a marketing layer.

FAQs

Frequently asked questions

Do you build on Magento, Shopify, or Shopware?

We do not position ourselves as a certified agency for any of those platforms. Our commerce work is custom engineering, typically for projects where SaaS platforms have become a constraint rather than an enabler. If your project is a standard storefront build, a certified agency for your chosen platform will likely deliver faster and at a lower cost. If your project involves complex B2B logic, deep ERP integration, or requirements that exceed what off-the-shelf platforms can deliver cleanly, that is where our engineering work fits.

How long does a custom commerce project typically take?

For a focused B2B portal or order management system with a defined scope, 6 to 9 months from kickoff to production launch is typical, including a parallel-run period before legacy system decommissioning. For larger custom commerce platforms with multi-channel scope, ERP integration, and advanced features like AI search or headless architecture, 9 to 14 months is more realistic. We are conservative about timelines because commerce systems handle real revenue, and late or buggy launches cost more than delayed ones.

Can you integrate with our existing ERP and finance systems?

Yes. ERP integration is a core part of our commerce work, especially for B2B projects where the ERP holds master data for pricing, inventory, and customer accounts. Our ERP integration experience covers platforms such as SAP Business One, Microsoft Dynamics, Odoo, and custom ERP cores. For larger enterprise ERP platforms, we work alongside your existing implementation team rather than claiming end-to-end ERP expertise.

What happens after launch, do you provide ongoing support and maintenance?

Yes. A commerce system is not a one-time delivery; it needs to evolve with your catalog, promotions, and integration changes. After go-live, we typically continue with a support and maintenance arrangement covering bug fixes, security patches, performance monitoring, and incremental feature work. The exact model depends on your needs, ranging from a defined SLA-based support package to a dedicated team that stays with the product long-term. For clients who prefer to take the system in-house, we provide documentation and a structured handover so your internal team can maintain it independently.
