The short version

  • Each has a real cost: ProShop ERP it runs on a Microsoft stack with Internet Information Services and SQL Server, so a shop choosing on premises deployment needs a Windows server and someone to maintain it, which is not what buyers expect when they hear browser based.; Siemens WinCC Unified licensing counts PowerTags, and archived tags are licensed separately from displayed tags, so a project that adds historian logging late can breach a tier and trigger an unbudgeted step-up purchase.
  • They diverge on capability: ProShop ERP covers Integrated quality management, Siemens WinCC Unified covers TIA Portal engineering.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

ProShop ERP

  • A machine shop pursuing or holding AS9100 registration that currently maintains quality records separately from its ERPnot Siemens WinCC Unified

Siemens WinCC Unified

  • Replacing a WinCC V7 plant SCADA before the 2027 support cut-off without changing controller vendornot ProShop ERP
  • A line supervisory system where operators and supervisors need browser access from tablets with no client software rolloutnot ProShop ERP
  • A plant already committed to the TIA Portal toolchain, where the cost of a rival SCADA is the second engineering environment and the second set of skills rather than the licencenot ProShop ERP

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ProShop ERP

  • It runs on a Microsoft stack with Internet Information Services and SQL Server, so a shop choosing on premises deployment needs a Windows server and someone to maintain it, which is not what buyers expect when they hear browser based.
  • The software is opinionated and expects the shop to adopt its processes, so a shop determined to keep its existing habits gets a poor result and blames the tool.
  • Everything depends on operators entering time and status at each operation, and a shop that cannot enforce that discipline ends up with costing and scheduling data that nobody trusts.
  • It is not a machine monitoring product and does not read controllers, so spindle utilisation and automatic cycle counting require a separate product such as a monitoring platform.
  • The partner ecosystem is very small, so implementation, training and any customisation come from the vendor, and there is no market of independent consultants to fall back on or to price against.

Siemens WinCC Unified

  • Licensing counts PowerTags, and archived tags are licensed separately from displayed tags, so a project that adds historian logging late can breach a tier and trigger an unbudgeted step-up purchase.
  • There is no migration tool that converts a WinCC V7 project to Unified, so leaving the classic line before its 2027 support end means rebuilding screens, scripts and alarm configuration by hand.
  • Scripting moved from VBScript to JavaScript, which invalidates the script libraries in-house engineers accumulated over a decade on classic WinCC.
  • It is effectively bound to the Siemens controller stack; connecting Rockwell or Mitsubishi PLCs works through OPC UA but loses the shared tag database that is the main reason to buy it.
  • Three unrelated products share the WinCC name, and buyers who specify WinCC without saying Unified, V7 or OA regularly receive quotes for the wrong platform with different licensing and a different contractor pool.

Answered from the vendors’ own pages

ProShop ERP: Is it cloud software?

It is browser based and can be vendor hosted, but many customers run it on their own Windows server, which carries the usual infrastructure obligations.

Siemens WinCC Unified: Should I buy WinCC Unified or WinCC V7?

Unified, for any new project. V7 and V8 receive no new features and support ends in 2027.

ProShop ERP: Does it replace my accounting system?

No. It handles costing and purchasing and integrates with QuickBooks or similar for the general ledger.

Siemens WinCC Unified: Is WinCC OA the same product?

No. WinCC OA came from ETM, has its own engineering environment and licensing, and is aimed at very large distributed systems. It shares only the brand.

ProShop ERP: Will it work with old CNC machines?

Yes, because it takes operator input at kiosks rather than reading machine controllers. That is a strength for shops with older equipment.

Siemens WinCC Unified: What is a PowerTag?

An externally connected process variable in the runtime. Internal tags do not count, but archived tags are licensed separately from displayed ones.

ProShop ERP: Is it suitable for process or batch manufacturing?

No. It is built for discrete machining and fabrication with routings and travellers.

Siemens WinCC Unified: Can operators use it from a browser without installing anything?

Yes, the runtime is HTML5, but concurrent browser clients need WebUX or Unified client licences.
