Microsoft's 2026 Wave 1 release for Business Central runs April through September. For staffing operations, a few things in this release are worth a close look — both for what they deliver today and for what they signal about where the platform is heading.
The Payables Agent Gains Real Utility
The Payables Agent — which processes vendor invoices directly from your email inbox — ships a meaningful update in Wave 1: it now surfaces which emails it has already handled. For staffing firms, the context is worth spelling out. Managing contractors and suppliers — including the mixed workforce models that are increasingly common — has long been part of 1Staff's back office capability. Timesheet data flows through to accounts payable and payroll without rekeying. What the Payables Agent adds is automation for the rest of your supplier base: facilities, software, professional services, the operational spend that sits outside the staffing workflow. It closes the loop on AP more broadly, not just the staffing-specific side that's already handled. And the new visibility into what the agent has processed is what makes it trustworthy enough to run in production rather than just a proof of concept.
Microsoft is also shipping the ability to stop and review agent tasks directly from BC pages. Built-in oversight, not an afterthought — which is the difference between a feature that runs in a demo and one you can actually deploy.
Custom Agents Are Coming to the Platform
The longer-term signal in Wave 1 is a visual agent designer arriving in May. Admins and developers will be able to design and prototype custom AI agents inside Business Central, using the same AI infrastructure Microsoft builds its own agents on.
For staffing firms on BC — including those running 1Staff — this opens the door to automation that's genuinely native to your financial data. Timesheet-to-invoice matching, contractor compliance reminders, payroll exception alerts — built within the platform rather than connected to it from outside. The compounding benefit of building on infrastructure that Microsoft is actively investing in, rather than a standalone system that has to develop everything independently, becomes more tangible with every release wave.
Financial Management Updates Worth Noting
Two additions arrive in June. Native self-billed invoice support in BC will bring a smile to plenty of staffing firms — it's a long-overdue addition to the core platform. 1Staff customers have had this for a while, along with VMS reconciliation that takes it further: matching self-billed invoices back against VMS data to resolve discrepancies before they become payment disputes. The BC update validates the approach; 1Staff takes it the rest of the way.
Withholding tax calculation for vendors also arrives in June. For firms managing 1099 contractors in the US, this brings a compliance step that too often lives in spreadsheets or outside the ERP entirely into the core system where it belongs.
The GP Migration Tooling Keeps Improving
Wave 1 adds two pieces that matter for firms evaluating a move to Business Central. Cloud migration now supports any SQL database as a source, broadening the on-ramp beyond Dynamics GP and NAV. And a reimplementation-specific migration path arrives in May — designed for firms that want a clean-slate approach rather than a direct data migration from their legacy system.
December 2029 is the Dynamics GP end-of-life date. Migration and implementation projects for a back-office system of this scope typically take two to three years from decision to go-live. The tooling is improving, but the planning window is the constraint.
The Broader Picture
Wave 1 2026 isn't a single transformative release. Taken together, though, it reflects a platform that's consistently moving in the right direction for service businesses — AI automation with real governance, financial workflows better suited to staffing billing models, and lower-friction migration paths for firms on legacy infrastructure. Staffing firms that track these release cycles and align their technology roadmaps accordingly tend to be better positioned than those waiting for a single moment to act.

Microsoft has announced Bridge to the Cloud 3 (BTC3), a time-limited licensing promotion for organizations still running Microsoft Dynamics GP and planning a transition to the Microsoft cloud.
