When Startups Pay in Cash and Equity: Key Considerations for Software Development Arrangements
For many emerging technology companies, securing critical software development talent often requires creative approaches to compensation. It is increasingly common for startups to compensate developers and engineering partners not only with cash but also with equity. While this approach can be attractive for early-stage companies seeking to conserve cash, it introduces a range of legal and commercial complexities.
If not carefully structured, mixed-compensation arrangements can lead to misaligned incentives, disputes over deliverables, and unexpected dilution. To establish a successful long-term relationship and protect both parties, startups should address key legal, financial and operational considerations at the outset and ensure these are clearly documented in the contractual terms.
Below are several important issues to consider when negotiating these arrangements.
1. Clearly Defined Deliverables and Milestones
At the core of any mixed payment arrangement is clarity regarding what the developer will deliver and when.
2. Intellectual Property (IP) and Ownership Rights
Intellectual property is often the most critical risk area. Without robust IP provisions, startups may risk losing rights to core elements of their product or becoming exposed to open-source license obligations.
3. Structuring Equity Compensation
Equity is not “free” compensation; it represents future ownership and control. Structuring equity grants in exchange for development services therefore requires careful consideration.
Each instrument carries different tax, dilution and liquidity implications. Factors influencing the choice of instrument may include the size of the startup’s option pool, the stage of development of the business, the value of the services provided, and the startup’s cash flow position.
While a startup may wish to conserve cash, the vendor may prefer not to assume full risk through equity alone. As such, a negotiated balance between cash and equity compensation is often required.
Valuation. A key issue for all parties will be the valuation at which equity is issued or convertible instruments convert.
If an equity instrument converts at a future date, the parties must determine whether it will convert at the same price as a future funding round or at a discounted price to reflect the earlier contribution of the vendor’s services. Vendor’s may also seek a valuation cap to better understand the potential percentage ownership resulting from their contribution.
If a convertible instrument is used, the parties should also consider whether the loan amount will accrue interest.
Vesting. Where equity compensation is tied to development services, vesting should typically be linked to the completion and acceptance of defined milestones. This helps align incentives and reduces the risk that equity is granted for incomplete or substandard work.
Additional mechanisms such as cliffs, performance triggers and continued engagement requirements can further reinforce alignment.
4. Tax and Securities Law Considerations
Equity compensation can trigger complex tax and securities law implications. Engaging legal and tax advisers early can help avoid issues during future financing rounds or tax filings. Both the startup and the vendor should understand how the equity compensation will be taxed, including any tax consequences arising upon grant, issuance or vesting.
5. Service Levels and Remedies
Where the vendor will also provide ongoing maintenance or support services to the startup, additional contractual protections should be considered.
6. Exit Rights and Termination Flexibility
Startups should retain sufficient flexibility to exit development arrangements if business priorities change.
Clear termination mechanisms help ensure that the startup is not locked into an unworkable relationship or over-committed to equity grants that cannot be recovered.
Conclusion
Compensating software developers with a combination of cash and equity can be a powerful tool for startups seeking to preserve capital while attracting high-quality development partners. When structured carefully—with clear deliverables, milestone-based equity vesting, strong IP protections, defined service levels, and flexible exit rights—these arrangements can effectively align incentives and support long-term collaboration.
However, to realize these benefits while mitigating risk, startups must ensure that expectations, rights and remedies are documented with precision. Ambiguities around deliverables, equity vesting or termination rights can disrupt product development and complicate future financing.
If your startup is considering this approach, engaging experienced legal advisers early can help ensure the arrangement is structured effectively. The right framework not only protects the startup’s core assets but also supports sustainable growth with clarity and confidence.

Below are several important issues to consider when negotiating these arrangements.
1. Clearly Defined Deliverables and Milestones
At the core of any mixed payment arrangement is clarity regarding what the developer will deliver and when.
Detailed Scope of Work. The contract should describe the expected functionality, features, performance requirements and technical standards in clear and measurable terms. This will typically require close engagement between the technical teams of both the startup and the vendor to ensure alignment on the scope of work and to minimize disputes later.
Milestone-Based Payments. Development work should be divided into meaningful phases tied to objectively defined contractual milestones. This supports predictable cash flow and ensures that equity vesting events occur only upon satisfactory completion of milestones pursuant to agreed acceptance criteria. In many cases, the client’s principal remedy will be the ability to withhold payment, so it is generally advisable to avoid advance payments.
Acceptance Criteria and Testing Protocols. The contract should clearly define how deliverables will be tested and accepted, including objective testing procedures and acceptance criteria. It should also specify the consequences if those criteria are not met. For example, the parties may agree that deliverables may still be accepted subject to agreed fee reductions, or that the startup may terminate the contract if acceptance criteria are not met after a specified number of remediation attempts. Objective acceptance testing—such as feature checklists, performance benchmarks, or quality assurance protocols—can significantly reduce disputes.

2. Intellectual Property (IP) and Ownership Rights
Intellectual property is often the most critical risk area. Without robust IP provisions, startups may risk losing rights to core elements of their product or becoming exposed to open-source license obligations.
Assignment of IP Rights. Where the vendor is creating custom work (for example, software code) for the startup, all deliverables and work product created under the engagement should be assigned to the startup upon creation. This should apply to any partially completed work or drafts, particularly if the contract is terminated early.
The vendor should not retain ownership of the code itself, although it may retain ownership of its pre-existing IP (such as tools, methodologies or know-how incorporated into the deliverables). In those cases, the vendor should grant the startup a broad, perpetual license to use such materials.
From an operational perspective, the startup should ensure that all code developed by the vendor is appropriately backed up and that the startup always has access to it. The vendor should not be in a position to withhold or restrict access to the code.
Open Source and Third-Party Code. Even where code is developed specifically for the startup, vendors may incorporate open-source or third-party components. Unless carefully managed, this can create significant legal risks.
The vendor should therefore be required to disclose any third-party or open-source components used in the deliverables and confirm compliance with all relevant licensing obligations. Some startups may also seek approval rights before such components are incorporated, although this can create additional operational complexity.
Definition of Deliverables. The contract should clearly specify that all deliverables—including source code, documentation and related materials—will be provided in usable formats and in accordance with the agreed scope of work.

3. Structuring Equity Compensation
Equity is not “free” compensation; it represents future ownership and control. Structuring equity grants in exchange for development services therefore requires careful consideration.
Type of Equity Instrument. There are several mechanisms through which a vendor may receive equity or equity-linked instruments, including:
- Share options
- Warrants
- Convertible loan notes
- Sweat equity
Each instrument carries different tax, dilution and liquidity implications. Factors influencing the choice of instrument may include the size of the startup’s option pool, the stage of development of the business, the value of the services provided, and the startup’s cash flow position.
While a startup may wish to conserve cash, the vendor may prefer not to assume full risk through equity alone. As such, a negotiated balance between cash and equity compensation is often required.

Equity compensation can trigger complex tax and securities law implications. Engaging legal and tax advisers early can help avoid issues during future financing rounds or tax filings. Both the startup and the vendor should understand how the equity compensation will be taxed, including any tax consequences arising upon grant, issuance or vesting.
Valuation for Equity Payments. Equity compensation should generally be valued at fair market value, with careful consideration given to the resulting dilution.
VAT Considerations. The parties should consider whether the services are subject to VAT or fall outside the VAT regime (for example, where the vendor is located outside the UK). Where VAT applies, it is generally advisable for VAT to be paid in cash so that the company can preserve its ability to reclaim input VAT.

5. Service Levels and Remedies
Where the vendor will also provide ongoing maintenance or support services to the startup, additional contractual protections should be considered.
Service Levels. The contract should clearly define the service levels expected from the vendor. These may include platform uptime or availability commitments, response and resolution times for support requests or bug fixes, escalation procedures, and reporting obligations.
Clear incident classifications and response commitments help ensure that issues are addressed promptly and that the startup’s operations are not disrupted.
Remedies for Service Failures. Where service levels are not met, the contract should specify the remedies available to the startup. These may include service credits, fee reductions or adjustments to future payments.
Termination for Persistent Failures. If the vendor consistently fails to meet agreed service levels, the startup should have the right to terminate the contract. The contract should also address the treatment of any equity granted to the vendor in such circumstances, including potential clawback or forfeiture of unvested equity.

6. Exit Rights and Termination Flexibility
Startups should retain sufficient flexibility to exit development arrangements if business priorities change.
Clear termination mechanisms help ensure that the startup is not locked into an unworkable relationship or over-committed to equity grants that cannot be recovered.
Termination for Convenience. The startup should ideally have the right to terminate the contract for convenience—for example, if funding conditions change or strategic priorities shift. Vendors may resist such rights and may seek termination fees to compensate for early termination.
Vendor Termination Rights. Conversely, the vendor’s ability to terminate should typically be limited to circumstances where the startup materially breaches the contract. This is particularly important where the vendor is responsible for business-critical systems that the startup may not be able to operate internally.
For similar reasons, the vendor’s right to suspend services should also be carefully limited.
Consequences of Termination. The contract should clearly address the consequences of termination, including:
