Research and development (R&D) is a crucial aspect of any startup. It is the engine that drives innovation and growth, enabling companies to develop new products and services that meet the ever-evolving needs of their customers. However, R&D can be a costly endeavor, and it's essential for startups to manage their cash flow effectively to ensure their survival and long-term success. In this article, we'll explore how startups can get started with R&D and maximize their cash flow, including when and how to start the documentation process for R&D and how to catch up or work retroactively if you decide to get an R&D study but hadn't been planning on it.

Getting Started with R&D

The first step in getting started with R&D is to define your objectives. What are you trying to achieve with your R&D efforts? Are you looking to develop a new product or service, or improve an existing one? Once you have a clear understanding of your objectives, you can begin to develop a plan for achieving them. This plan should include a timeline, budget, and a list of resources that you'll need to achieve your goals.

Maximizing Cash Flow

One of the most significant challenges that startups face when it comes to R&D is managing their cash flow effectively. There are several strategies that startups can use to maximize their cash flow while still investing in R&D:

Prioritize your R&D projects: Not all R&D projects are created equal, and it's essential to prioritize your projects based on their potential return on investment. Focus on the projects that are most likely to generate revenue or provide a competitive advantage.

Monitor your expenses: Keep a close eye on your R&D expenses and make sure that they align with your budget. This will help you to avoid overspending and ensure that you have enough cash to fund your R&D efforts.

Manage your inventory: If your R&D efforts involve the development of physical products, it's essential to manage your inventory effectively to avoid tying up too much cash in unsold products.

Leverage government incentives: There are several government incentives available to startups that can help to offset the cost of R&D. Principal among those is the R&D tax credit. For start-ups, this credit can provide up to $250,000 in payroll tax offsets if you qualify.

To qualify for the federal R&D credit, a company must pass the four-part test established by the IRS. This test ensures that the research activities meet specific criteria to be considered eligible for the credit. The four parts are:

Permitted Purpose: The research must be intended to create new or improved business components, including products, processes, computer software, techniques, formulas, or inventions that result in new or improved functionality, performance, reliability, or quality.

Elimination of Uncertainty: The company must demonstrate that it has attempted to eliminate uncertainty about the development or improvement of a product or process. This can include determining the capability of designing a product, the method of manufacturing or developing it, or the appropriate design of the product or process.

Technological in Nature: The research must be based on the hard sciences, such as engineering, computer science, biological sciences, or physical sciences. The IRS does not consider activities relying on social sciences, such as economics or arts, to be eligible.

Process of Experimentation: The company must demonstrate a process of experimentation that includes testing, modeling, simulation, systematic trial and error, or other methods that are used to evaluate one or more alternatives.

To claim the credit, the company must also have incurred qualified research expenses (QREs) in the tax year. These expenses can include wages paid to people directly involved in the development, supplies used or consumed during the development process, and contract research expenses paid to a third party for performing qualified research activities on the company's behalf.

For startups and small businesses, the Protecting Americans from Tax Hikes (PATH) Act of 2015 introduced new provisions to make the credit more accessible. These include the ability to offset payroll tax liabilities with the R&D credit and expanding eligibility for the startup refundability portion of the credit.

It's important to keep detailed records of all R&D-related expenses and work to support claims for the R&D credit. This documentation can include invoices, receipts, lab notebooks, and other records. Maintaining accurate and complete records can help ensure that a company can successfully claim the credit and avoid potential issues with the IRS.

Documentation Process for R&D

Documentation is a critical part of the R&D process, as it provides evidence of the work that has been done and the results that have been achieved. This documentation can be used to support claims for government incentives, such as the R&D tax credit, and can also be useful when seeking investment or partnerships.

The documentation process should begin as early as possible in the R&D process. This includes keeping detailed records of all expenses related to R&D, including salaries, materials, and equipment. It's also important to document the work that has been done, including any experiments, prototypes, and test results.

Catching Up or Working Retroactively

If you decide to get an R&D tax credit study but hadn't been planning on it, it's still possible to catch up or work retroactively. The first step is to gather all the documentation that you have related to your R&D efforts. This may include invoices, receipts, lab notebooks, and other records.

Once you have all of your documentation, you'll need to organize it in a way that makes it easy to understand and review. This may involve creating a timeline of your R&D efforts or categorizing your expenses by type.

If you're missing any documentation, you may be able to reconstruct it based on other records or by working with your team to recall what was done. However, it's always best to have complete and accurate documentation from the beginning.


In conclusion, R&D is a critical component of any startup's success, but it's essential to manage cash flow effectively to ensure long-term sustainability. By prioritizing R&D projects, monitoring expenses, leveraging government incentives, and managing inventory effectively, startups can maximize their cash flow while still investing in R&D. Additionally, by starting the documentation process early and keeping detailed records of all R&D-related expenses and work, startups can ensure that they have the evidence they need to support claims for government incentives and other purposes.
