Vending Software Change History: Find Out Who Changed a Price or Product Mapping
WEIMI INSIGHTS / SOFTWARE CONTROLS
When a setting changes, the explanation should remain available.
Ask how the platform records operational changes so the team can investigate discrepancies without relying on chat messages.
WHO
Identify the authorised user or process.
WHAT
See the relevant old and new values.
WHEN
Connect the change to the machine timeline.
Ask for a demonstration of the platform’s change records for the operations you care about, including their limits; a user account list is not the same as a usable change history.
01 / BUYER NOTES
Start with the changes that affect customers
Prices, product mappings and availability settings can alter what a customer sees or receives. List the changes your operation needs to trace and ask which are recorded by the platform. Do not assume every administrative action appears in the same log.
Include stock adjustments and other important operator actions where relevant. Clarify whether an entry reflects a request sent from the dashboard or a change confirmed on the machine. Those can occur at different times, especially when a cabinet is temporarily offline.
02 / BUYER NOTES
Inspect a real record rather than a feature label
Ask the supplier to make a controlled demonstration change and show the resulting entry. Look for the affected machine or product, time, user or process and the values needed to understand the event. A log entry saying only “updated” may not answer the operational question.
Confirm the time zone and how automated actions are identified. If a scheduled job or integration changes a value, the record should be interpretable without blaming the last person who opened the dashboard. Keep the explanation grounded in the platform’s actual behaviour.
03 / BUYER NOTES
Connect permissions and records sensibly
Use named accounts and appropriate roles under the operator’s access policy. Shared credentials can make even a detailed log less useful because the account name does not identify the person who acted. Confirm what the system supports before designing the process.
Restrict access to operational records according to their purpose and sensitivity. A refill worker may need current stock information without needing a full administrative history. Review who can view, export or manage records and keep the responsibilities clear.
04 / BUYER NOTES
Agree retention and investigation procedures
Ask how long relevant records remain available, whether they can be exported and what happens when service changes or ends. Use the business’s appropriate retention requirements to guide the decision. Do not assume the dashboard keeps every event indefinitely.
When investigating a mismatch, compare the change record with the machine state and transaction timeline. Preserve the relevant evidence through the approved process. A recorded update can explain part of an incident, but it does not automatically prove that every downstream effect occurred as intended.
Check what each record can establish
User and time
Can help: Identify the account or process and event timing.
Limit: Shared accounts can obscure the actual actor.
Changed values
Can help: Explain which price or mapping was revised.
Limit: Some logs may not retain all fields or prior values.
Machine confirmation
Can help: Show whether an update reached the cabinet.
Limit: A dashboard request alone may not prove application.
PRACTICAL ANSWERS
Questions about operational change records
Does having staff accounts mean the software has an audit trail?
No. Account management and change logging are separate capabilities. Demonstrate the records for the actions you need to trace.
Can a log prove a machine used the new price immediately?
Only if the relevant confirmation evidence supports that conclusion. Check how the platform distinguishes a requested update from an applied one.
Should logs be kept forever?
Use the applicable business, legal and privacy requirements to define retention. Confirm what the provider supports and document the arrangement.
YOUR NEXT STEP
Include operational traceability in the software review
Ask the supplier to show a controlled change from dashboard action through machine confirmation and record retrieval. Evaluate the evidence your team would need during a real discrepancy.
