How to Structure an EV Conversion Revenue Share Agreement: What Hong Kong Garage Owners and Automotive Partners Need to Negotiate Before Signing

A revenue share agreement for EV conversion partnerships is a contract that defines how income from each completed conversion is divided between the technical conversion provider and the referring or co-delivering partner, whether that is a garage, dealership, or fleet operator. In Hong Kong's emerging EV conversion market, conversion specialists must meet stringent road-legal compliance standards [7], and getting this contract right before you sign is not administrative housekeeping - it is the commercial foundation of your entire partnership. This article explains every clause that matters, the negotiation points that catch partners off guard, and how to build a structure that works for both sides over the long run.

TL;DR

• A revenue share agreement in EV conversion defines which party receives what portion of each job's income, and under what conditions.

• The core negotiation points are: revenue base definition, split percentage, milestone triggers, exclusivity, and liability allocation.

• Hong Kong's legal framework requires specific drafting care around service descriptions, consumer protection, and IP ownership [5].

• Using a solid revenue share contract template saves time, but it must be adapted to reflect the technical realities of EV conversion - generic templates miss critical items like warranty responsibility and road-legal certification.

• The cleaner the contract, the more scalable the partnership - especially as EV conversion volumes grow under Hong Kong's 2050 zero-emission roadmap [7].

What Exactly Is a Revenue Share Agreement in the EV Conversion Context?

A revenue share agreement is a commercial contract that specifies how the money generated from a sale or service is allocated between two or more parties [1]. In EV conversion, this typically means the party who sources or refers the client (a garage, dealer, or automotive business) and the party who performs the technical conversion (a certified specialist) agree in advance on how each completed job's income is divided.

This matters more in EV conversion than in most automotive services because the work is technically complex, legally regulated, and capital-intensive. Unlike a simple referral arrangement, both sides often contribute meaningfully: one party brings the client relationship and physical space; the other brings patented technology, certified engineers, and road-legal compliance. A well-drafted agreement recognises both contributions precisely.

• Revenue base: Is the split applied to gross income, net of parts costs, or net of all operating expenses?

• Service scope: Does the agreement cover bespoke individual conversions, fleet jobs, or both?

• Trigger point: Does the split apply at invoice, at payment receipt, or at job completion sign-off?

What Should Every Revenue Share Contract Template Include?

Building on the definition above, the harder question is what distinguishes a workable revenue share contract template from one that collapses under real-world pressure. A robust template for EV conversion partnerships must address the following [4]:

Contract Section	What It Must Specify	EV Conversion-Specific Consideration
Party Identification	Full legal names, roles, and registration details [2]	Distinguish between referral partner, delivery partner, and end client
Revenue Definition	Gross vs. net; which revenue streams are included [3]	Clarify whether aftersales, warranty claims, and upsells are in-scope
Split Structure	Fixed percentage, tiered, or milestone-based	Tiered splits based on volume incentivise partner growth
Payment Schedule	Frequency, method, and reconciliation process [4]	Align with conversion completion milestones, not just invoice dates
IP and Technology	Who owns the conversion IP; licensing terms	Patented powertrain and battery systems must remain with the IP owner
Warranty Responsibility	Who fields and funds warranty claims	Critical: road-legal certification and warranty sit with the converter
Exclusivity Clause	Geographic or sector exclusivity, if any	Exclusivity must be time-bound and performance-conditioned
Termination	Notice periods, exit triggers, IP reversion [4]	Include a wind-down clause for jobs in progress at termination

How Should the Revenue Split Actually Be Calculated?

Stepping back from the structural checklist, a separate concern is the arithmetic itself - because the "right" split is not a universal number. It depends on what each party contributes to the conversion job [1].

Consider two common B2B models in EV conversion:

• Referral-only model: The partner identifies the client, manages the sales relationship, and hands the vehicle to the specialist. The specialist handles everything technical. In this model, the partner's share reflects sales and client management value only.

• Co-delivery model: The partner provides workshop space, handles intake logistics, and manages client communications throughout the conversion. The specialist supplies technology, engineers, and certification. The revenue split reflects a larger combined contribution, and both parties need clear cost-recovery provisions before the split is applied.

A common mistake is agreeing a percentage before defining the revenue base. If one partner interprets "revenue" as the gross invoice and the other interprets it as net of parts and materials, the first payment will trigger a dispute. Define it precisely, ideally with a worked numerical example in the contract's schedule [2].

What Hong Kong-Specific Legal Points Should Partners Watch For?

A related but distinct question is jurisdiction. Hong Kong contract law governs these agreements, and several local factors shape what a well-drafted revenue share agreement template must address [5].

• Consumer protection alignment: Service descriptions in the contract must match what is communicated to end clients. Hong Kong's consumer protection framework penalises misleading service representations, so the agreement's scope-of-work language should mirror client-facing materials.

• Road-legal certification accountability: EV conversions must meet Transport Department standards to be road legal [7]. The contract must state clearly which party holds regulatory accountability. This is non-negotiable and cannot be split ambiguously.

• Tax treatment of shared revenue: How shared revenue is recognised and reported has profits tax implications for both parties [6]. Each party should obtain independent tax advice rather than relying on the other party's interpretation.

• Dispute resolution: Specify Hong Kong as the governing jurisdiction and include a clear dispute escalation path - negotiation first, then mediation, then arbitration or litigation.

How Does Warranty and Aftersales Responsibility Affect the Agreement?

Building on the legal points above, the harder question for most partners is who owns the post-conversion relationship with the customer. This is where many partnership agreements underperform in practice.

In EV conversion, the warranty is not a marketing promise - it is a technical and financial commitment. A conversion that carries a multi-year unlimited mileage warranty requires the technical specialist to remain accountable for drivetrain performance over an extended period. The revenue share agreement must be explicit about:

• Which party receives and processes warranty claims.

• How warranty costs are funded - absorbed by the specialist, shared proportionally, or held in a reserve.

• What happens to the partner's revenue share if a vehicle requires significant remedial work within the warranty period.

• Whether aftersales service revenue (inspections, software updates, battery assessments) generates a separate share or falls within the original agreement's scope.

Leaving aftersales undefined is one of the most common causes of partnership breakdown at the 12-to-18-month mark, long after the initial excitement of signing.

Frequently Asked Questions

Q: Do I need a lawyer to draft a revenue share agreement in Hong Kong?

A standard revenue share agreement template [4] can provide a solid starting point, but any agreement involving IP licensing, road-legal certification, or consumer-facing warranties should be reviewed by a solicitor familiar with Hong Kong commercial law [5].

Q: What is a fair revenue split for an EV conversion referral partner?

There is no universal benchmark. The split should reflect each party's actual contribution - client sourcing, logistics, technical delivery, and certification. Enumerate those contributions explicitly before agreeing any percentage [1].

Q: Can a garage without high-voltage expertise participate in EV conversion partnerships?

Yes. A well-structured B2B partnership is specifically designed for partners without in-house high-voltage expertise. The certified specialist manages all technical work; the partner manages client relationships and vehicle intake. The agreement must reflect this division of responsibility clearly.

Q: What range should we communicate to clients after conversion?

Typical post-conversion range is 200 to 300 km WLTP, determined by the battery capacity that can be accommodated given the specific vehicle's space and weight constraints. Do not promise a fixed figure in marketing materials without a technical assessment.

Q: How does Hong Kong's 2026 EV policy environment affect these agreements?

Hong Kong updated its EV Roadmap in February 2026, targeting zero vehicular emissions before 2050 [7]. This creates a growing commercial opportunity for conversion partnerships, but also means regulatory requirements may evolve. Build a contract review clause that triggers whenever relevant regulations change.

Q: What revenue streams should be listed in the agreement?

Identify all current and foreseeable revenue streams upfront: the primary conversion fee, optional restoration or modification add-ons, aftersales services, and any future product lines [2]. Omitting a revenue stream creates ambiguity about whether it is covered.

Q: Should exclusivity be included in an EV conversion partnership agreement?

Exclusivity can benefit both parties if structured carefully. It should be geographically bounded, time-limited, and conditioned on the partner meeting agreed volume targets. Open-ended exclusivity without performance conditions exposes both sides to commercial risk [4].
