Unbilled parts and services due to disconnected ordering and work-order systems
Definition
Parts and labor used in the field or during shop maintenance are sometimes not captured on final invoices because ordering, inventory, and billing systems are not tightly linked. This leads to systematic underbilling for parts consumed in servicing electronic and precision equipment.
Key Findings
- Financial Impact: Industry CMMS/maintenance vendors highlight significant recoveries when automating parts-to-work-order linkage; in practice this often equates to low single-digit percentage of service revenue lost, which can reach hundreds of thousands of dollars annually for larger service providers
- Frequency: Weekly
- Root Cause: Manual entry of parts used, lack of enforced association between issued parts and customer/job records, and separate tools for inventory, work orders, and invoicing that do not reconcile automatically.

Financial Impact
$15,000 to $75,000 annually in unbilled parts (1-3% of typical lab service revenue of $2-5M annually) β’ $20,000 to $100,000 annually in unbilled component costs and internal chargebacks not allocated (1-2% of IT infrastructure service costs of $2-10M annually) β’ $40,000 to $150,000 annually in unbilled parts and labor (1.5-2.5% of telecom service revenue of $6-10M annually)
Current Workarounds
Coordinator maintains parallel Excel inventory tracking separate from work order system; technicians email parts usage summaries; monthly adjustment to invoices based on manual audit of consumed parts; some regions use WhatsApp groups to coordinate urgent parts requests β’ Coordinator tracks component pulls in hybrid system (part Excel, part Jira tickets, part Slack messages); IT staff often forget to log parts usage; manual reconciliation occurs during quarterly asset audits; vendor invoices sometimes include undocumented parts that were provided from IT stock β’ Coordinator tracks parts in local Excel files and Outlook tasks; technicians text/WhatsApp photo evidence of parts used; monthly manual reconciliation to match invoices; some sites use paper work orders that are never digitized
