This page provides an independent comparison of Clarus R+D’s publicly described model and the year-round internal documentation approach represented by R&D Ledger. For a broader framework, see our page on how to choose an R&D tax credit provider.
What Clarus R+D Publicly Offers
According to Clarus R+D’s current website, Clarus R+D provides an R&D tax credit platform that helps companies manage their study while ensuring compliance and saving time. The website describes the platform as secure, reliable, and designed to defend earned credits, with software derived from IRS guidelines that facilitates the collection of required R&D credit information.
Clarus R+D’s website describes four attributes: Defensible (secure and reliable platform derived from IRS guidelines), Secure (information in one place rather than shared by email), Efficient (simplifies the study workflow by distributing tasks, sending notifications to subject matter experts, and monitoring progress), and Cost-saving (streamlining the study to rely less on outside services).
Clarus R+D’s website states that the platform was built by tax experts from Big 4 accounting firms with over 30 years of R&D experience, and that the company offers both a full-service solution and a software-licensing option.
Provider and Engagement Model
Clarus R+D describes itself as a platform-plus-support provider. According to its website, companies can choose between a full-service solution (where Clarus R+D delivers the R&D study) or licensing the software to do it themselves. The website describes pricing as fixed-price for software and support packages.
This is a flexible model: a business can either have Clarus R+D handle the study using its platform and team, or license the platform and conduct the study internally.
How the Process Appears to Work
According to Clarus R+D’s website, the platform facilitates the collection of required R&D credit information, distributes tasks, sends notifications to subject matter experts, and monitors study progress. The website describes a workflow-oriented approach to managing the R&D study.
Documentation Approach
Clarus R+D’s documentation approach, as described on its website, involves the platform collecting required R&D credit information and organizing it in a secure, centralized location. The website states that the software is consistent and reliable, ensuring that IRS-required documentation is generated from the software.
Role of Software
Software is central to Clarus R+D’s model. According to its website, the platform incorporates processes and workflow to identify, document, and calculate credits efficiently, and generates IRS-required documentation. The software can be used as part of a full-service engagement or licensed for self-use.
Role of Human Professionals
Human professionals are involved in Clarus R+D’s model, particularly in the full-service option. According to its website, the platform was built by tax experts from Big 4 accounting firms, and the full-service solution involves Clarus R+D delivering the study. In the software-licensing option, the company’s own team uses the platform.
Year-Round vs. Study Considerations
Clarus R+D describes a study-workflow model with task distribution, notifications, and progress monitoring. This appears oriented toward the study engagement rather than continuous year-round documentation by the internal team. Year-round internal documentation, as represented by R&D Ledger, involves the business’s own team organizing project, technical, cost, and evidence records throughout the year for professional review.

What a Buyer Should Compare
A buyer evaluating Clarus R+D against year-round internal documentation software may consider:
- Full-service vs. self-service: Clarus R+D offers both a full-service study and a software-licensing option. Does the buyer want the provider to handle the study, or does it want to license software and do it internally?
- Study workflow vs. year-round documentation: Clarus R+D describes a study-workflow model. Does the buyer prefer a study-cycle approach or continuous year-round documentation?
- Task distribution: Clarus R+D describes distributing tasks and sending notifications to subject matter experts. Does the buyer’s team structure support this workflow?
- Fixed pricing: Clarus R+D describes fixed-price packages. How does this align with the buyer’s budget?
- Big 4 heritage: Clarus R+D states its platform was built by Big 4 tax experts. Does the buyer value this background?

When Clarus R+D’s Model May Make Sense
Clarus R+D’s model may make sense for a business that:
- wants a platform-based study workflow with task distribution and progress monitoring;
- is choosing between full-service and self-service options and wants flexibility;
- values a platform built by tax experts with Big 4 experience; and
- prefers fixed-price packaging.
When Year-Round Internal R&D Tracking May Make Sense
Year-round internal R&D documentation may make sense for a business that:
- wants to organize project, technical, cost, and evidence records throughout the year internally;
- already has a CPA who handles filing and needs organized records to support that work;
- prefers continuous documentation rather than a study-cycle workflow; and
- wants a documentation workspace that is not tied to a specific study engagement.

Can the Two Approaches Coexist?
A business could maintain year-round project and evidence records in a documentation workspace and also use a platform like Clarus R+D for the study workflow. The internal records could supply organized project, cost, and evidence data to support the study. The two approaches are not mutually exclusive: a business might use internal documentation for ongoing recordkeeping and a study platform for the credit computation and documentation generation.
Questions to Ask Before Choosing
- Does the business want a full-service study, a software license, or year-round internal documentation?
- How does the business’s team structure align with a task-distribution workflow?
- Does the business need a study-cycle platform or continuous year-round documentation?
- How does fixed-price packaging align with the business’s budget and expected benefit?
- Who will file the credit, and how does the platform integrate with the filing process?
Key Takeaway
Clarus R+D is a platform-plus-support provider that offers both full-service and software-licensing options for R&D tax credit studies, with a workflow-oriented platform built by Big 4-experienced tax experts. Year-round internal R&D documentation, as represented by R&D Ledger, involves the business’s own team organizing project, technical, cost, and evidence records throughout the year for professional review. The two approaches differ in workflow orientation and provider involvement, and a buyer’s choice depends on its preference for study-cycle vs. continuous documentation.
