ISSUE

Which Windows Server version is supported with your Invoices and/or Collector version is available here:

https://docshield.tungstenautomation.com/RSI/en_US/2025.1-9pbsxfw99k/print/TungstenReadSoftInvoicesDatabasesandOperatingSystemsFactsheet_EN.pdf

The documentation says "Enterprise Server" above the Windows Server version. But are other editions, such as the "Standard Server" or "Datacenter Server," supported?

SOLUTION

Yes, they are supported.

Explanation:

Standard vs. Datacenter, on the versions ReadSoft Invoices does support (2016 through 2025):

For a single physical (or already-virtualized) server hosting ReadSoft Invoices directly, Standard and Datacenter are functionally almost identical. Since 2012, Microsoft has removed the old CPU/RAM scalability gap between editions (in 2008 R2, Standard capped out at 32 GB RAM with no failover clustering, while Enterprise supported far more; that distinction is gone). In current versions, both editions support the same maximum number of sockets and memory, and both support failover clustering. So core stability, performance ceiling, and role support (IIS, .NET, SQL Server hosting, and so on) are the same either way.

The differences that remain are mostly virtualization-related, not application-related:

• Licensing rights for virtual machines: Standard licenses two virtual OS instances per license (stackable for more); Datacenter licenses unlimited VMs on the same host. This matters if ReadSoft Invoices (or its components, such as separate application and database servers) will run as multiple VMs on a single physical host, since a Datacenter can become more cost-effective at scale.
• Datacenter-only features: Storage Spaces Direct, unlimited Storage Replica (Standard is capped at a single partnership and a size limit), Shielded VMs, and Network Controller (software-defined networking). None of these are things ReadSoft Invoices itself requires or references in its documentation.

Where this could plausibly matter for a ReadSoft Invoices deployment specifically: if the environment plans a highly virtualized setup with many guest VMs per host, Datacenter's licensing model is the relevant driver, not any ReadSoft Invoices requirement. If there's a compliance or data-protection requirement around invoice/financial data (protecting VMs from host-level administrative access, for instance), Shielded VMs could be a reason to choose Datacenter, again as an infrastructure decision layered on top of ReadSoft Invoices, not something ReadSoft Invoices asks for.

Since the Windows Server edition choice ties directly into Microsoft licensing terms and costs, that part is worth confirming with your IT/procurement team or Microsoft's own licensing guidance, rather than treating it as a Tungsten product requirement.

ReadSoft Invoices itself will run the same either way.
