Asset-as-a-Service is no longer a slide in a strategy deck — it’s how equipment makers want to sell. Microsoft just put rental inside the Dynamics 365 ERP core, from quote to fleet to general ledger, with agents doing the assembly work. That’s a sharp contrast to rivals still pointing customers toward partner add-ons.

The Idea Was Never the Hard Part

Every equipment manufacturer has run the same whiteboard exercise: stop selling machines once, start renting them, servicing them, and eventually selling them again. Recurring revenue, stickier customers, a fleet that earns money for years.

Then the ERP gets in the way. Rentals touch availability, pricing, contracts, logistics, inspections, maintenance, billing, fixed assets, and depreciation — usually spread across a rental package, a service system, a billing engine, and a ledger that only sees the result.

Georg Glantschnig, Microsoft’s Corporate Vice President of AI ERP, nails the problem in one line: “The constraint on a new business model is rarely the idea.” It’s the plumbing. And Microsoft’s move is to stop treating rental as an edge case and make it a native process in Dynamics 365.

What Microsoft Actually Shipped

Rental Management in Dynamics 365 Supply Chain Management is now in public preview, bringing core rental processes into Finance and Supply Chain Management, with new rental capabilities coming to Field Service and Commerce. The scope is the point — this runs the whole asset lifecycle, not just the rental counter:

• Quote to contract: Coordinators check availability across prime equipment, attachments and bulk items, build quotes in a guided rental cart and convert them to contracts, including a rental purchase option.
  
• Pricing that protects margin: Suggested rates flex with inventory levels, utilization, reservations and customer history, with discount override limits.
  
• Fleet operations: Shipments and returns with inspection checklists, photos and damage tracking, call-offs that stop charges, return-to-ready to get units back on rent faster, on-site swaps and location transfers.
  
• Billing and finance: Invoices follow the contract’s billing cycle, best-rate calculation runs at close, and transactions post straight to the general ledger, fixed assets and accounts receivable — with revenue-based depreciation and per-unit utilization tracking.
  
• Full lifecycle: A unit moves from new inventory to rental fleet (as a fixed asset), to used fleet for sale, to customer fleet once sold.
  
• Service and counter: In Field Service, rental-linked repairs carry contract context into work orders, and fleet items get preventive maintenance by calendar or actual usage. In Commerce, Trade Counter POS lets associates build big B2B orders and check stock across branches.
  

Glantschnig’s framing of that last mile is the one CFOs should remember: “Ownership changes. The relationship doesn’t have to.”

From Customer Email to Rental Quote

Here’s where it gets interesting. Microsoft demonstrated a Dynamics 365 ERP apps plugin for Copilot Cowork that takes a customer’s emailed request, identifies suitable equipment, checks availability, drafts a reply and starts the rental quotation — then hands it to a human for review. It works within existing security roles and data permissions.

“The coordinator stays in control; the agent does the assembly,” Glantschnig wrote. That’s a crisp summary of how agentic ERP should work in a margin-sensitive business like rental.

And it only works because rental now lives in the same system as inventory, pricing, fleet and finance. As Glantschnig put it: “An agent is only as useful as the processes and data it can reach.” An agent can’t assemble a quote if availability sits in one app, rates in another, and the asset register in a third.

Meanwhile, at SAP and Oracle

Compare that with how the other two ERP heavyweights handle the same problem.

SAP supports rental through a combination of existing ERP capabilities, subscription services, and partner solutions. Its own product pages feature specialized rental offerings, including FIT Group’s FIT-Rent, built on SAP Business Technology Platform and integrated with S/4HANA Cloud Public Edition, and BearingPoint Lease & Rent. These can be capable products, but depending on the implementation, customers may face additional vendors, contracts, integration requirements, and upgrade cycles. That’s a potential disadvantage in an agentic ERP world, where AI agents work best with seamless access to business processes and data.

Oracle approaches Asset-as-a-Service through capabilities spanning service, subscriptions, and asset management. Its Asset-Based Service offering, unveiled in 2022, sits within Oracle Fusion Service and focuses on monitoring, maintenance and field service for installed assets. Subscription Management supports recurring and usage-based billing, while other Oracle applications provide capabilities for inventory management, order orchestration, asset management and financial accounting. But, connecting those pieces into a complete equipment-rental lifecycle can introduce complexity.

On Oracle’s own customer forum, users have asked how to model equipment rental and returns in Oracle Cloud Order Management — illustrating the kind of implementation questions that Microsoft’s new native rental process aims to simplify.

The pattern: SAP combines core ERP capabilities with partner rental solutions, while Oracle draws on service, subscription and asset-management applications. Microsoft is betting that rental is a core ERP process that belongs next to the ledger — which is exactly where agents can use it.

The Cloud Wars Take

In the agentic era, “we have a partner for that” is turning from an answer into a liability. Every extra system between a customer request and the general ledger is another place an agent has to be integrated, governed and paid for in tokens. Native processes win because agents can actually reach them.

Microsoft is still in preview here, with no general availability date, pricing, named customers or results yet — so the proof is still to come, and partners will matter for industry-specific needs. But, the strategic direction is clear: make new business models a configuration choice, not an integration project.

If you’re an equipment maker weighing a move to Asset-as-a-Service, the question for your ERP vendor is simple: does rental run in your core, next to my ledger, where my agents can use it? Microsoft just answered yes.
