Connecting van stock, service parts and purchasing to the job

01 / Operational context
Why the existing process breaks down
Service inventory moves constantly. A part may be in central stock, in a technician’s van, reserved for a job, installed on a machine, returned, ordered or received. If stock, service and invoicing are separate, the business can complete the repair while losing the inventory and margin record.
Available stock cannot be trusted
Recorded quantity may not identify whether the part is in the warehouse, in a van or already committed.
Transfers create false stock
A poor movement process can increase both locations instead of moving the same units between them.
Installed parts are missed
The technician fits the component, but it does not reach the stock movement or invoice.
Purchasing is disconnected from demand
A purchase order may not identify the jobs and machines waiting for the item.
Catalogue data is inconsistent
Names, part numbers, buy prices and sell prices can vary between records.
Stocktake becomes reconciliation
The team spends time explaining differences instead of confirming a trusted operating record.
The inventory integrity problem
When the service record, stock record and invoice record describe different versions of the same part movement, the business loses confidence, time and margin.
02 / Corexa response
A connected workflow around the machine
Corexa keeps the asset, service event, people, parts and next commercial action in one traceable workflow. The goal is not simply to digitise forms; it is to stop operational context from breaking between steps.
Identify
Connect the required component to the machine and job.
Locate
Check central or technician inventory.
Move
Transfer stock without creating an artificial increase.
Consume
Record the installed part against the job and machine.
Replenish
Purchase, receive and progress waiting jobs.
Capability, operational change and value
Separate location inventories
Central stock is distinguished from technician and van stock.
The team can answer where the available unit is located.
Controlled stock movements
Transfers, receipts and job consumption create movement records.
Quantity changes have an operational explanation.
Job-part linkage
Installed and required components connect directly to service work.
The job, machine history and invoice can reference the same part.
Purchase-order workflow
Supplier ordering and receiving connect to service demand.
Waiting jobs remain visible while the required part moves through purchasing.
Buy/sell pricing
Cost, sell price and margin can be reviewed together.
The business can identify missing prices and protect service-parts margin.
Stocktake and movement history
Reconciliation is supported by a structured movement record.
Differences can be investigated against movements rather than guesswork.
03 / Evidence and measurement
What is supported — and what is not yet claimed
A credible case study distinguishes observed facts, product capability and future hypotheses. The evidence level is deliberately explicit.
Product capability
Corexa contains inventory locations, technician inventory, stock movements, parts, jobs, purchasing and receiving workflows.
Operational relevance
The use case reflects van-stock, installed-part, purchase-order and invoice-omission risks.
Evidence boundary
No stock-accuracy or margin improvement is claimed without a measured stocktake baseline.
Pilot readiness
A pilot can be limited to one warehouse, two vans and a selected group of high-use parts.
Not yet claimed
This article does not claim a verified stock-accuracy percentage, recovered margin or reduction in purchasing spend. Those figures need a physical baseline and controlled movement period.
Measurement plan
Stock accuracy
- Evidence source
- Blind physical count against system quantity
- Credible reporting
- Accuracy by line and by inventory value.
Installed-part capture
- Evidence source
- Technician records compared with invoice lines
- Credible reporting
- Percentage of installed parts recorded and charged.
Transfer integrity
- Evidence source
- Source and destination movement audit
- Credible reporting
- Percentage of transfers with equal and opposite movement.
Job delay due to parts
- Evidence source
- Job status history and required-part records
- Credible reporting
- Median waiting time and number of jobs delayed.
Margin-data completeness
- Evidence source
- Part buy prices, sell prices and invoice lines
- Credible reporting
- Percentage of used parts with complete and reviewable margin data.
“The inventory record should explain where a part came from, where it went and which machine received it.”
04 / Visual proof and rollout
Show the workflow, then verify the outcome
Visual credibility comes from real screens with precise captions. Each image should identify the user, the workflow stage and the evidence it proves.
Baseline count
Choose 30–50 frequently used parts and complete a blind count across one warehouse and two vans.
Controlled movement
Require all receipts, transfers and job consumption to use the agreed workflow for 6–8 weeks.
Recount and report
Repeat the blind count, reconcile differences and publish only verified findings.
Build the publishable proof layer
One warehouse, two vans and a selected high-use parts list can produce more credible evidence than a broad, unmeasured inventory claim.
