Comparing Work 365 and CSP Control Center: Why Work 365?
Work 365 and CSP Control Center (C3) are both used by Microsoft CSP partners to automate and manage Microsoft cloud subscriptions and billing. Microsoft requires direct CSP partners to run an order processing and billing automation system as part of the CSP program, and either platform can meet that bar.
The question in a real evaluation is not whether a platform can send an invoice. It is how well it fits the way your business runs today and where you want to take it. Work 365 is a revenue operations platform built natively on Microsoft Dynamics 365 and Power Platform. C3 is a standalone SaaS application. That single difference shapes most of what follows. This article walks through architecture, features, integrations, extensibility, and support so you can decide which fits your organisation.

Product architecture
Work 365 is built on Dynamics 365 and Power Platform. C3 is an independent, standalone SaaS application. For many teams this is the deciding factor.
With Work 365: your users sit in your own directory, and you control security, licences, and access the way you would for any other application in your Microsoft tenant. Your customers, subscriptions, and pricing live in your own Dataverse environment, alongside the rest of your business data, which makes account management and renewals far easier. Because the data is yours, you can build any report you need directly in Power BI rather than being limited to prebuilt views. This is also what lets Power Platform extend Work 365 well beyond billing.
With C3: you can often get started without much involvement from internal IT, which can suit smaller teams or those with limited technical resources. Your data sits in the vendor environment, and reporting is delivered through prebuilt, summarised dashboards that are ready to use out of the box.
C3 can be faster to stand up, and Work 365 can take a little longer for teams new to Dynamics 365. The trade is flexibility: if owning your data and extending the platform matters to you, the Power Platform foundation gives you a secure, scalable, and adaptable base to grow on.
Features
Provisioning and subscription management
Both platforms integrate with Microsoft Partner Center and distributors, support Microsoft Indirect Resellers and Direct CSPs, and keep pace with NCE and Microsoft program changes. Both handle Microsoft licences, Azure usage subscriptions, bundles, add-ons, non-Microsoft products, and one-time items.
Work 365 adds bidirectional sync with Partner Center and distributors including Pax8, Ingram Micro, Crayon, and TD SYNNEX, along with a Provider API. Its subscription management supports different provider types, scheduled subscription changes, detailed audit and change logs, product bundling, mix and match scenarios, and advanced subscription calculations. Subscriptions can be created from the Dynamics product catalog with custom pricing and discounts, and Work 365 also tracks time and bills service based tasks. Keeping renewals under control is a big part of this, and it is a topic worth reading on its own if you are managing renewal complexity.
Billing automation and price management
Both platforms offer advanced billing automation such as proration, refunds, custom pricing, and discounts at the customer or subscription level. Work 365 adds price indexation, which automatically adjusts subscription prices at renewal based on factors like inflation or promotions, and a set of tools for handling Microsoft price changes: automatic catalog updates across categories, segments, and currencies, current price lists, price rules that flag and update affected subscriptions, and notifications for new, legacy, and changed products.
Invoices come up in almost every evaluation. Work 365 generates invoices from Microsoft Word templates, supports multiple templates and formats, and gives clear detail on every line item, which reduces confusion for the end customer. Azure invoices can be rolled up and grouped by parameters such as charge type or tags.
Self-service for end customers
Both platforms give end customers a way to manage subscriptions, buy additional services, request provisioning changes, and view or pay invoices. The difference is control: Work 365 self-service is built on Power Pages, so you own the branding and decide exactly what data to surface to your customers, which lets you build a differentiated experience rather than a generic one.
Pre-built integrations
Both Work 365 and C3 integrate with QuickBooks, Xero, Autotask, and ConnectWise. Work 365 adds native integrations with Dynamics 365 Business Central and NetSuite, uses the standard Dynamics invoice entity, and, through the Dataverse, lets partners connect to hundreds of ERP and accounting systems or build their own. You can see the full list on the integrations page.

Because Work 365 runs on Dynamics 365 and Power Platform, it can be customised and extended through form changes, plug-ins, and workflows, so you can tailor it to your own processes. It is built on the Dataverse, a secure and scalable platform where you keep full control of your data and choose what to expose to customers through self-service. Subscription billing left unmanaged can quietly leak recurring revenue, which is why a single source of truth for customer, subscription, and billing data matters, and why so many partners are moving from reactive reconciliation to finance-led governance.
Infinity Group
Infinity Group brought its Microsoft CSP billing onto Work 365, running it alongside its existing C3 setup rather than attempting a single rip and replace. With billing on a reliable foundation, the team went on to reach Microsoft Frontier Partner status. It is a clear example of the phased approach: start with billing, then bring the rest across when you are ready.
Support
Every Work 365 customer gets a dedicated Customer Success Manager, and because the team spans multiple time zones you get timely, expert help. Work 365 also runs live Office Hours four days a week with Customer Success and Engineering, to work through technical questions and share best practices for specific use cases.
Which is right for you?
If you want a platform that can be stood up quickly with minimal IT involvement, C3 is a capable, established option. If you want a platform that aligns billing with your sales process, scales your recurring revenue as your commercial contracts and the Microsoft program evolve, handles bundles and complex scenarios, keeps your data in your own Microsoft environment, and can be extended across your whole organisation, Work 365 is built for that. It is a strong fit for Microsoft CSP partners in particular. Many partners also move in phases, starting with billing and bringing the rest across when they are ready, so it does not have to be a single rip and replace.
Frequently asked questions
Is Work 365 a replacement for CSP Control Center?
Both help Microsoft CSP partners meet the order processing and billing requirements of the CSP program. The differences that matter in an evaluation are architecture, extensibility, reporting, and support rather than basic capability.
What is the main architectural difference?
