Introduction

This Product Warranty & Customer Support Statement (the “Warranty”) is issued by Etheeden Technologies Limited (“Etheeden”, “we”, “us”), the developer and operator of the ZedCarHire car-rental and fleet-management platform (the “Product”) and its integrated ZRA Smart Invoice (VSDC) module.

It governs the warranty coverage, customer-support commitments and Service Level Agreement available to ZedCarHire subscriber companies (the “Subscriber”), with particular focus on the Smart Invoice integration. Its specific purpose is to give the Zambia Revenue Authority β€” and every Subscriber β€” full confidence that users of ZedCarHire’s Smart Invoice features receive comprehensive, prompt and competent support throughout the subscription lifetime.

πŸ“ž
Single point of contact for Smart Invoice

Etheeden Technologies is the designated single point of contact for every Smart Invoice query that arises through the ZedCarHire platform. Subscribers are not required to contact ZRA directly. Our support team handles all triage, diagnosis and β€” where a fix is needed on ZRA's side β€” escalation to ZRA on the Subscriber's behalf.

This Warranty supplements, and is read together with, the ZedCarHire Subscriber Agreement, Privacy Policy and the ZedCarHire Product User Manual (ZCH-PM-2.1). Where there is any conflict, the Subscriber Agreement prevails.

Article 1

Warranty Coverage

Subject to the exclusions in Article 10, Etheeden Technologies warrants to the Subscriber that, during the Warranty Period, the Product will:

  1. Substantially conform to the documentation published in the ZedCarHire Product User Manual;
  2. Be free from material software defects that prevent the Subscriber from performing core fleet management, hire processing, accounting, customer management and Smart Invoice submission tasks;
  3. Be operated on infrastructure that meets or exceeds an availability target of 99.5% measured monthly, excluding scheduled maintenance windows;
  4. Transmit Smart Invoice data to the Zambia Revenue Authority Virtual Sales Data Controller (VSDC) using the request and response formats prescribed by ZRA, and faithfully store the resulting resultCd and resultMsg values returned by ZRA;
  5. Preserve every Smart Invoice request/response pair in a tamper-evident audit log retained for not less than seven years β€” see Article 8.
Article 2

User Support Commitment

Etheeden Technologies commits, for the duration of each active ZedCarHire subscription, to provide the Subscriber with the following β€” included at no additional charge in the subscription token model:

2.1 Free on-boarding

Every new Subscriber receives a one-on-one guided on-boarding session led by our Customer Support Lead, covering platform basics and a complete walkthrough of Smart Invoice setup: device initialization with ZRA, fetching standard codes, fetching item classification codes, and the first end-to-end customer and vehicle registration with ZRA.

2.2 Continuous documentation

The full ZedCarHire Product User Manual (ZCH-PM-2.1) β€” including a dedicated Smart Invoice section covering setup, daily operation, error codes and troubleshooting β€” is freely available to every Subscriber both in-platform and as a downloadable PDF.

2.3 Multi-channel support desk

Subscribers reach our support team through any of the channels listed in Article 12 (phone, WhatsApp, email and an in-platform ticket form). All channels feed a single ticket queue with named owners.

2.4 Proactive monitoring

Our team monitors all VSDC submissions made through the ZedCarHire platform. Failed or anomalous submissions are flagged automatically; we investigate and reach out to the affected Subscriber proactively β€” often before they are aware of the issue.

2.5 Ongoing training

Follow-up training sessions on Smart Invoice features are available throughout the subscription at no additional cost β€” including refresher sessions for new staff hired by the Subscriber.

Article 3

ZRA Smart Invoice β€” Single Point of Contact

For every Smart Invoice-related concern β€” whether technical, procedural or regulatory β€” the Subscriber contacts Etheeden Technologies first. We then own the resolution end-to-end. The Subscriber is never required to contact ZRA directly.

1
Subscriber raises the issueVia any support channel β€” phone, WhatsApp, email or in-platform ticket. A ticket is opened immediately with a unique reference.
2
Etheeden Tier-1 acknowledges & triagesOur Customer Support Lead (Lombe Ngandu) acknowledges within the SLA window, classifies the issue and resolves immediately if it is a usage, configuration or training question.
3
Etheeden Tier-2 takes over technical issuesIf the issue is integration- or software-level, our Lead Developer (Iden Zulu) and Senior Developer (Martin Mwale) investigate, reproduce and fix on the ZedCarHire platform side.
4
Etheeden engages ZRA on the Subscriber’s behalfIf diagnosis shows the root cause lies on ZRA's side β€” for example a VSDC API change, an unexpected resultCd, reference-data drift or a TPIN-validation discrepancy β€” our Smart Invoice Lead contacts ZRA directly through the operational channels established at certification.
5
Etheeden keeps the Subscriber informedThe Subscriber receives status updates on the original ticket. Any ZRA reference number obtained is captured against the ticket.
6
Etheeden closes the loopOnce resolved we re-test the affected workflow, confirm the resolution with the Subscriber, record the closure in the Smart Invoice debug log and document any recurring pattern in the Product User Manual.
πŸ›‘οΈ
The Subscriber never has to engage ZRA directly.

Etheeden Technologies maintains the technical relationship with ZRA, holds the institutional knowledge of VSDC error codes and change notices, and is the named operational contact established during Smart Invoice certification.

Service Level Agreement (SLA)

5.1 Availability target

Etheeden Technologies targets 99.5% monthly uptime for the production ZedCarHire platform, excluding scheduled maintenance announced at least 48 hours in advance.

Article 6

ZRA Liaison Process β€” Operational Detail

When Tier-2 investigation determines that the root cause of a Smart Invoice issue lies on ZRA's side, the following operational steps are executed by Etheeden Technologies β€” without further action required from the Subscriber:

  1. Diagnosis package assembled. Etheeden compiles the exact VSDC request/response pair, the affected Subscriber's TPIN, branch ID, timestamp, user actions that triggered the issue and our preliminary analysis.
  2. Direct engagement with ZRA. Etheeden's Smart Invoice Lead contacts ZRA through the operational channels established during certification (email, phone or designated portal). A ZRA ticket reference is requested and captured.
  3. Internal mitigation. Where a temporary workaround is possible from the ZedCarHire side (e.g. deferring submission until ZRA resolves), Etheeden implements and explains it to the Subscriber.
  4. Subscriber kept informed. Status updates are posted to the original ticket; the Subscriber receives written progress notifications until closure.
  5. Closure verification. Once ZRA confirms a fix, Etheeden re-tests the affected workflow under both sandbox and production conditions, then confirms resolution with the Subscriber.
  6. Knowledge capture. The incident, the ZRA resultCd / resultMsg involved and the resolution are added to the Smart Invoice section of the Product User Manual so the next Subscriber encountering the same situation is resolved faster.
πŸ“
Subscriber participation is minimal

The Subscriber's only requirement is to respond to any clarifying questions Etheeden asks during step 1. Etheeden handles everything else β€” including holding the relationship with ZRA β€” under this Warranty.

Article 7

Software Updates & ZRA Compliance

The Product is a cloud-hosted Software-as-a-Service offering. Etheeden Technologies deploys software updates, security patches and feature enhancements regularly. Every Subscriber is automatically entitled to all updates published during the Warranty Period at no additional cost.

7.1 Update categories

7.2 ZRA compliance updates

Changes published by the Zambia Revenue Authority that affect the Smart Invoice API are tracked by Etheeden Technologies and reflected in the Product within 14 calendar days of publication, or sooner if mandated by ZRA. Subscribers are notified in advance of any change that may affect their day-to-day Smart Invoice operations.

Article 8

Audit Trail & Data Warranty

Etheeden Technologies warrants that:

Article 9

Training & On-boarding

Within the first 30 days of activation, every new Subscriber receives a one-on-one on-boarding session, conducted by Etheeden's Customer Support Lead, covering at minimum:

Refresher training and additional sessions for new staff hired by the Subscriber are available throughout the subscription at no additional cost.

Article 10

Exclusions & Limitations

This Warranty does not cover, and Etheeden Technologies shall not be liable for, any defect, downtime or data issue arising from:

  1. Force majeure β€” nationwide internet outages, ZRA VSDC outages, electricity-supply failures, natural disasters, civil unrest, government action or pandemic-related restrictions.
  2. Subscriber misuse β€” modification of the Product, unauthorised access attempts, use outside the documented operating envelope, or circumvention of the token, subscription or licensing systems.
  3. Third-party services β€” failures or changes in services not operated by Etheeden, including GPS hardware vendors, mobile-money operators, email delivery providers and the Subscriber's own network or device.
  4. Subscriber-supplied data β€” incorrect TPIN, NRC, branch identifiers, item classification codes or other data submitted by the Subscriber that causes ZRA to reject a submission. (Where this occurs Etheeden will still raise the ticket, diagnose the cause and advise the Subscriber β€” see Article 3.)
  5. Beta features β€” any feature explicitly labelled “Beta”, “Experimental” or “Preview” in the Product or documentation.
⚠️
Smart Invoice rejection

When ZRA returns a non-000 result code, Etheeden Technologies' role is to display the verbatim error message, preserve the local record for re-submission and β€” if the diagnosis shows the issue is on ZRA's side β€” engage ZRA directly on the Subscriber's behalf as described in Articles 3 and 6.

Article 11

Remedies

The Subscriber's sole and exclusive remedies under this Warranty are, at Etheeden Technologies' option:

  1. Repair β€” Etheeden will use commercially reasonable efforts to correct the defect within the SLA windows defined in Article 5.
  2. Replacement β€” provision of an alternative feature path or process to achieve the same business outcome.
  3. Service credit β€” issued as a token-balance credit applied to the Subscriber's account, as described in Article 5.3.
  4. Termination & refund β€” where a P1 defect is not resolved within 30 calendar days, the Subscriber may terminate the subscription and receive a pro-rata refund of any unused token balance.
πŸ›‘
Limitation of liability

To the maximum extent permitted by law, Etheeden Technologies' total liability under this Warranty in any rolling 12-month period is limited to the total amount paid by the Subscriber to Etheeden (token top-ups) in the preceding 12 months. Etheeden is not liable for any indirect, incidental, consequential, special or punitive damages.

Article 12

Governing Law & Contact Details

This Warranty is governed by, and construed in accordance with, the laws of the Republic of Zambia. Any dispute arising out of or in connection with this Warranty shall first be resolved through good-faith negotiation and, failing resolution within 30 days, by arbitration in Lusaka under the rules of the Chartered Institute of Arbitrators (Zambia Branch).
