E-commerce systems

Connect your retail site, trade portal, warehouse and back office

Established e-commerce businesses often run separate systems for their website, stock, warehouse and accounts. Syngis builds software that connects these systems properly — or builds integrated platforms that bring them together from the start.

What we connect

Eight systems. One operational picture.

Most e-commerce operations touch all of these. The question is whether they share data reliably, or whether people fill the gaps manually.

Retail storefront

Product catalogue, pricing, promotions, checkout and customer journeys.

Trade and B2B portal

Account-specific pricing, bulk ordering, approvals and credit controls.

Warehouse and fulfilment

Pick, pack, dispatch, barcode scanning and courier integration.

Stock and inventory

Live stock levels, reservations, reorder points and multi-location.

Customer accounts

Order history, invoices, returns, account management and preferences.

Shipping and courier

Rate calculation, label printing, tracking and carrier integration.

Reporting and analytics

Sales reporting, stock movement, fulfilment metrics and back-office dashboards.

Finance and accounts

Order and invoice data fed into your accounts or ERP system.

The problem

Disconnected systems create operational drag.

When your systems don't talk to each other, your team works around the gaps. That means manual re-entry, delayed fulfilment, pricing errors and a lack of operational visibility.

These problems compound as order volumes grow. What was manageable at 50 orders a day becomes a serious bottleneck at 500.

Common symptoms

Your website shows stock levels that don't reflect what's actually in the warehouse.
Trade customers see the wrong pricing or have to call to place an order.
Fulfilment teams get notified about orders late or through a manual process.
Orders need to be re-entered into your accounts system by hand.
You can't see a complete view of order status across website, warehouse and shipping.
Integrating a new platform or service requires months of custom development.

What we build

Integrated e-commerce software, built around your operation.

We design and build the software layers that connect your customer-facing systems with your operational and back-office systems.

Retail storefronts

Fast, manageable customer-facing sites with live stock data, promotion management and checkout workflows.

Trade portals

Custom trade ordering systems with account-specific pricing, approval workflows, repeat ordering and self-service account tools.

Warehouse software

Fulfilment tools for picking, packing, barcode scanning, label printing and courier dispatch — integrated with your other systems.

APIs and integrations

Purpose-built integrations between your website, stock system, warehouse, shipping carriers, CRM, accounts and ERP.

Reporting dashboards

Custom back-office reporting and operational visibility tools built around your actual data.

Integration layer

Purpose-built APIs, event-driven integrations and data pipelines between your existing systems — without replacing everything at once.

Proof in practice

Commerce and warehouse work we've delivered.

Anonymised examples of e-commerce and fulfilment software we've built for established operations.

From a legacy Access database to bespoke e-commerce

The problem: An established online operation was running on a legacy Microsoft Access database that had reached its ceiling for performance, reliability and growth.
What we built: We replaced it with a modern, bespoke e-commerce solution designed around how the business actually trades — rather than forcing it into a generic off-the-shelf template.
Why it mattered: The business gained a faster, more reliable platform it could keep growing on, free of the limits of ageing technology.

A warehouse picking app built for speed

The problem: Pickers were losing time tracking down stock in the warehouse, slowing the whole fulfilment process.
What we built: We built a picking app, heavily optimised for speed, that helps staff locate and pull stock as quickly as possible.
Why it mattered: Pickers find stock far faster, keeping orders moving through the warehouse.

Touch-screen pack-and-scan stations

The problem: Packing orders without item-level verification leads to mispicks — wrong items shipped, costly returns and unhappy customers.
What we built: We built large touch-screen packing stations where staff scan each item as it's packed, confirming the order is right before it leaves the building.
Why it mattered: Mispicks fall, and orders are packed quickly, correctly and consistently.

Our approach

Integration done properly.

Connecting systems reliably requires understanding the data, the business rules and the edge cases — not just writing an API call.

Understand

We map your current systems, data flows and the operational pain points before designing any solution.

Design

We define the integration architecture: what connects to what, how data flows, and what happens when things go wrong.

Build

We implement the integration cleanly, with proper error handling, logging and monitoring.

Test

We test against real business data and edge cases before going live. Integration testing is not optional.

Technology

Built on reliable, maintainable technology.

We use .NET, SQL Server, REST APIs, Azure Service Bus and modern web technologies for integration work — chosen for reliability and long-term maintainability, not novelty.

REST APIs and webhooks

Standard, documented integration patterns.

SQL Server

Reliable relational data for business-critical systems.

Azure hosting

Scalable, monitored infrastructure.

Custom connectors

Where standard patterns don't fit your system.
