A refrigerator breaks in a supermarket. The repair depends on a part. That part sits somewhere inside a second supply chain: the one supplying the equipment that keeps the first supply chain working. A retailer can be excellent at moving groceries and still leave a technician waiting. SDI has built its business around that awkward gap.
- SDI combines parts data, purchasing, and storeroom operations for maintenance teams.
- Its ZEUS platform connects the buying process; its people help run it.
- The useful measure is whether the part helps complete a repair, alongside what it costs.
In a 2023 case study, SDI described an unnamed retailer with nearly 12,000 stores worldwide. Technicians bought thousands of parts through multiple channels and hundreds of suppliers. Refrigeration failures threatened sales while maintenance waited for materials. The troublesome handoff was between the purchasing process and the person trying to fix the equipment.
The other supply chain
SDI works in maintenance, repair, and operations, usually shortened to MRO. Think bearings, replacement components, facilities supplies, and protective equipment. These purchases keep assets running without becoming the product a customer buys. They can be scattered across plants, departments, suppliers, and local habits. That fragmentation gives a missing component plenty of places to hide.
The company serves manufacturers, retailers, schools, and other organizations with equipment and facilities to maintain. Its homepage displays customer names including Boeing, Walmart, AbbVie, and the New York City Department of Education. The common thread is operational complexity. Someone must connect the maintenance requirement to an accurate parts record, an available supplier, and a workable delivery plan.
For the retailer, SDI connected parts management with ServiceChannel, the customer’s work-order system. ZEUS brought together ordering, inventory, catalogs, supplier management, and transaction processing. Shipment integrations added tracking. SDI reported better technician productivity and first-call completion. The practical idea: make buying a part part of completing the job.

It started with four pieces of paper
SDI began in 1971 as Industrial Systems Associates, above a Philadelphia hardware store. Its early improvement program tackled the paper trail linking requisitions, purchase orders, receiving, and invoices. In 1980, it opened its first on-site In-Plant Store program at Yale in Philadelphia. The business was already moving from arranging a transaction to managing the work around it.
That history explains its current position. A distributor can supply the component. Procurement software can organize a request. SDI offers services spanning both the transaction and the storeroom. Its supplier-neutral positioning matters because customers may need products from many sources. Grainger or Fastenal can be alternatives for MRO programs and participants in the wider supplier network.
“Our mission is to change the way people think about and manage supply chain.”SDI · Company mission
ZEUS, launched in 2019, supplies the shared purchasing interface: catalogs, approvals, ordering, and visibility. Around it sit sourcing specialists, supplier management, data cleansing, analytics, and storeroom teams. Customers can engage selected services or outsource a broader operation. It is a business selling managed execution, with software supporting the people responsible for delivering it.
The brewery test
An older customer account makes that labor visible. In a 2014 brewery case study, SDI described managing more than 40,000 SKUs, with over 60 on-site personnel supporting ten storerooms. The work included purchasing, receiving, stocking, issuing, and inventory control, with round-the-clock support. A catalog was only one piece of the assignment.
Annual savings reported by SDI through warranty, repair, and engineering work.
Historical customer result. Not a forecast.SDI also reported eliminating nearly $8 million of obsolete inventory and expanding the program to seven additional sites. Those figures show why a maintenance supply chain deserves attention beyond discounts. Inventory can absorb cash long after its usefulness disappears. Repair and warranty decisions can change the bill before anyone negotiates another purchase.
A separate confectionery case described eight sites implemented in under six months, with net savings exceeding a first-year target of 10.5%. These are SDI’s published customer results. For a buyer, the sensible next step is to establish the baseline: inventory value, purchasing expense, service levels, and implementation work. Savings percentages need that context to become a business case.
Trust is an integration requirement
At Ascend Performance Materials, the difficulty included master data ownership, cumbersome material-cost updates, and a backlog of invoices. SDI’s integration account describes an IT team concerned about procurement control and the effort of connecting SAP to another platform. The process had become hard to reconcile, and confidence in the data suffered.
SDiConnect provided a bridge between SAP and SDI’s procurement environment, replicating transactional changes between systems. Ascend staged the rollout to limit disruption. The account says that staging option carried no additional charge. That specific concession helps explain the change in confidence: the team could introduce the integration in manageable steps while addressing the reconciliation problem.
The lesson a reader can copy is operational. Decide who owns each record, how changes travel, and which system settles a disagreement. Then connect the purchasing and maintenance measures. Automating ambiguous ownership can simply spread the ambiguity faster. Likewise, cutting every slow-moving spare is a poor rule when one rarely used component protects an essential machine.
A new owner, the same handoff
Architect Equity acquired SDI from LLR Partners in March 2026. The company’s history also lists 2026 launches for AIM, its AI-driven inventory forecasting platform, and ZEUS PX, a mobile ordering and truck-stock app. Each addresses another decision along the route from identifying a need to having a usable part.
The model asks customers to coordinate purchasing, IT, and maintenance. Its appeal grows with the cost of fragmented records and repeated handoffs. A straightforward operation with few suppliers may need less help. For a sprawling facilities network, the question is wonderfully concrete: when the refrigerator stops, can the technician get the part?
