Ecommerce businesses grow fast — and the systems that worked at £1m turnover break down at £5m. Orders flood in from multiple channels: your own website, Amazon, eBay, Shopify. Stock needs to be accurate across all of them simultaneously. Customers expect next-day delivery, instant updates, and effortless returns. And your finance team is drowning in spreadsheets, trying to reconcile it all at month end.

The root cause is almost always the same: disconnected systems. A separate platform for each channel, a standalone accounting package, and a warehouse that runs on gut feel and clipboards. As volumes grow, the cracks become crises — overselling, stock write-offs, margin erosion, and customer complaints that damage your reputation faster than your marketing can build it.

Microsoft Dynamics 365, and in particular Dynamics 365 Business Central, is purpose-built for this challenge. It connects your sales channels, inventory, warehouse, finance, and customer data into a single real-time system — so every part of your business is working from the same accurate picture.

Finsys Apps configures and implements Dynamics 365 for ecommerce businesses across the UK and Europe. Whether you sell direct-to-consumer, B2B, or across a mix of marketplaces and your own store, we build the system around how your business actually operates — and how you plan to grow.

Overselling is one of the most damaging things that can happen to an ecommerce brand. A customer places an order, you take their money, and then you have to tell them the item is out of stock. Dynamics 365 eliminates this by maintaining a single, real-time inventory record that updates automatically every time an order is placed — across every channel, simultaneously.

AI-powered demand forecasting helps you stay ahead of peaks — whether that’s Black Friday, a seasonal spike, or a viral product moment — so you always have the right stock in the right place at the right time, without tying up cash in slow-moving lines.

Selling across multiple platforms is a strength — until your systems can’t keep up. Dynamics 365 integrates natively with the UK’s most widely used ecommerce platforms, pulling orders, customer data, and payment information directly into your ERP the moment a transaction occurs. No manual imports, no overnight batch files, no reconciliation headaches.

Whether you are selling on Shopify, through Amazon Seller Central, on eBay, or via your own WooCommerce or Magento store, every order flows into a single system — giving your operations team one place to manage fulfilment, and your finance team one source of truth for revenue.

Speed and accuracy in fulfilment is what separates the ecommerce businesses that win repeat customers from those that live and die by acquisition spend. Dynamics 365 automates the entire fulfilment workflow — from order receipt through pick, pack, despatch, and carrier handover — reducing the manual steps that slow you down and cause errors.

Returns are handled just as smoothly. A structured returns management process keeps your stock accurate, your refunds timely, and your customers informed — protecting your reviews and repeat purchase rate even when things go wrong.

Ecommerce profitability is notoriously difficult to measure accurately. Platform fees, fulfilment costs, returns provisions, and payment processing charges all eat into your margin — but most accounting systems can’t break this down at the product, channel, or order level. Dynamics 365 connects your operational data directly to your financial ledger, so your accounts reflect reality in real time.

Manage VAT across multiple jurisdictions, handle multi-currency transactions, automate reconciliation from your payment gateways, and produce management accounts without the month-end scramble. Power BI gives you the dashboards to understand your true profitability by product, channel, and customer segment.
