Sage 200 integration: connecting your CRM, website and other systems

Updated 29 September 2026

Sage 200 is often the financial heart of a business, but it rarely works alone. Orders arrive from a website, customers are managed in a CRM, stock moves through a warehouse system, and someone ends up typing the same information into two or three places.

Integration fixes that. Done well, data flows automatically and Sage 200 stays the single source of truth for your accounts. Done badly, it quietly creates duplicates and mismatches that surface at month end.

The ways into Sage 200

Which route you use depends on your version and how Sage 200 is hosted.

The Sage 200 API. Sage provides a web API for Sage 200, documented on its developer portal. It’s the route for Sage 200 Standard, the online version, and is also available for Sage 200 Professional. Most modern integrations use it.

The Sage 200 SDK. For on-premise Sage 200 Professional, the .NET SDK gives deep access to the application’s business logic. It’s typically used for more complex integrations and add-ons.

Import tools. For simpler, periodic jobs, Sage 200’s own import routines can be enough, and don’t need any development at all.

What they have in common is that data goes in through Sage’s own business logic. That matters, as you’ll see below.

Common integrations

CRM. Customers, contacts, account balances and credit status flowing between Sage 200 and systems such as Salesforce, Microsoft Dynamics, Zoho or HubSpot, so sales teams see what finance sees.

E-commerce. Orders, customers, stock levels and prices synchronised with Magento (Adobe Commerce), WooCommerce, Shopify and similar platforms, so web orders don’t need re-keying.

Warehouse and operations. Stock, despatches and purchase orders shared with warehouse or production systems.

Telephony. A caller’s account, balance and recent orders popping up on screen when they ring, from the same data held in Sage.

Other platforms. Running Sage 200 alongside a platform such as Odoo during a staged move, with each system handling what it does best.

Getting it right

Most integration problems come from a handful of decisions made too quickly at the start.

Decide which system owns each piece of data. If customers can be edited in both the CRM and Sage, you need a clear rule for which one wins, or you’ll end up with two versions of the truth.

Never write straight to the database. It’s tempting because it’s quick, but it bypasses Sage’s own checks and can leave your ledgers inconsistent. Use the API, the SDK or the import tools.

Choose the right timing. Some things need to be near real time, such as stock levels on a website. Others, such as nightly invoice exports, are better in scheduled batches.

Plan for failure. Networks drop and records get rejected. A good integration logs every failure, retries sensibly and tells someone when it needs attention, rather than silently missing an order.

Test in a test company. Sage 200 lets you run a separate test company. Use it, with realistic data, before anything touches your live accounts.

Off-the-shelf connector or bespoke?

For common pairings, such as Sage 200 with a popular e-commerce platform, an off-the-shelf connector may do the job and is usually the cheapest option. Bespoke integration makes sense when your processes don’t fit the connector, when several systems are involved, or when you need something no connector offers. It’s worth getting an independent view before committing either way.

How we can help

We’ve built integrations across the Sage range, from Sage Line 50 and Sage 200 to Sage Line 500 and Sage 1000, alongside CRM, telephony and Odoo. We work independently, so we’re happy to work alongside your Sage partner, and we’ll tell you if an off-the-shelf connector would serve you better than something bespoke.
