What iMetal and Prof.IT are
Jonas Metals Software develops two ERP lines for the metals supply chain. iMetal serves enterprise operations; Prof.IT serves small and midsize companies.
Both cover the commercial and operational cycle of metal distributors, service centers, traders, and processors: quoting and order management through processing, inventory, warehouse execution, and dispatch, ending in financial integration. The company works from offices in Southern California and the United Kingdom and is part of Jonas Software.
Company and product background
What looks like one vendor is really several, stacked. The US roots run back to Compusource, a California firm that began serving the metals industry in the 1970s; Jonas Software acquired the operation in the early 2000s and rebranded it Jonas Metals US. Metalogic followed, a UK vendor formed in 2000 through the merger of two British metals-systems suppliers, and then PCI Systems, which had been building integrated IT for the metals trade since 1981. The three units were merged into Jonas Metals Software.
Jonas Software itself is an operating group of Constellation Software, the Toronto-based consolidator of vertical-market software companies. Constellation also owns 4GL Solutions, vendor of the separate Steel Manager III product.
Functional scope
iMetal, the enterprise line, aims at larger distributors and processors: multi-currency and multi-language support, linear nesting and coil optimization for processing, API data links, and full quote-to-cash coverage. Prof.IT packages the same core ground for smaller organizations with less configuration effort, spanning selling and quoting, order management, processing, purchasing, inventory, warehouse execution, and logistics.
Both lines handle what generic systems fumble in this industry: dimensional inventory, heat and cast traceability, and processing carried out in-house as well as subcontracted. The orientation is toward financial integration rather than generic manufacturing workflows.
Target market, deployment, and pricing
Customers are metal wholesalers and stockholders, service centers, traders and importers, and fabricators and processors, with an installed base across North America and the United Kingdom that mirrors the merged predecessor companies. The two-line split lets the vendor cover the vertical from a single-warehouse distributor up to a multi-site international group.
Cloud and on-premises operation are both offered, though the vendor website says little in public about hosting models. Pricing follows the same pattern: nothing published, individual proposals after a demo and scoping discussion. Implementation, data migration from legacy systems, and training belong in the budget next to license or subscription fees.
Where it wins, where it loses
Read Jonas Metals Software as the consolidation vehicle for several decades-old metals ERP vendors. That history buys deep domain functionality and gives legacy Compusource, Metalogic, and PCI customers a defined upgrade path, which is the strongest argument in its favor.
The two-line strategy reads as coherent on paper. Push on it anyway: ask which line receives the bulk of development investment, and how the roadmap relates to sibling company 4GL Solutions, which sells Steel Manager III into the same vertical. Companies where metal handling is incidental rather than the core of the business have no reason to carry an industry-specific suite; a general ERP with a capable inventory module covers that case. Anyone still running a predecessor product should plan the move to iMetal or Prof.IT as a genuine migration project, not a routine upgrade. And a US metals distributor comparing specialized suites should run a structured selection process that tests processing, traceability, and integration scenarios against at least one metals-capable general ERP before signing.
