Year-Round vs. Study Considerations
BDO describes an accelerated study process (from months to weeks). This is oriented toward a study engagement rather than continuous year-round documentation by the internal team.

What a Buyer Should Compare
A buyer evaluating BDO against year-round internal documentation software may consider:
- Technology-enabled service vs. internal documentation: BDO provides technology-enabled R&D credit services. Does the buyer want a firm to conduct the study with its technology, or does it want to organize records internally?
- AI trend analysis: BDO describes AI for trend analysis. Does the buyer value this?
- Accelerated timeline: BDO describes reducing study time from months to weeks. Does the buyer need a fast turnaround?

When BDO’s Model May Make Sense
BDO’s model may make sense for a business that:
- wants a large firm with technology-enabled R&D credit services;
- values AI-powered trend analysis and accelerated study timelines;
- needs federal, state, and international R&D credit support;
- wants tax controversy and exam support; and
- prefers a professional-service engagement with technology support.
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 engagement; and
- wants a documentation workspace that can support any CPA or consultant.

Can the Two Approaches Coexist?
A business could maintain year-round project and evidence records in a documentation workspace and also engage a firm like BDO for the technology-enabled study. The internal records could supply organized project, cost, and evidence data to support BDO’s data ingestion and analysis. The two approaches are not mutually exclusive: a business might use internal documentation for ongoing recordkeeping and a firm for the accelerated study and controversy support.
Questions to Ask Before Choosing
- Does the business want a technology-enabled service from a large firm, or does it want to organize records internally?
- How important is AI-powered trend analysis?
- Does the business need an accelerated study timeline?
- Does the business need international R&D credit support?
- How does the firm’s fee structure align with the expected benefit?
Key Takeaway
BDO is a large accounting and advisory firm that provides technology-enabled R&D tax credit services with AI for trend analysis, efficient data ingestion, accelerated study completion, and tax controversy support, with a global network for international credits. 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 who conducts the study and the role of technology, and a buyer’s choice depends on its preference for technology-enabled service vs. internal documentation.
