R&D Ledger helps teams document technical experiments and organize workflows, making CPA-ready tax credit handoffs simpler and faster.

Examples of R&D work by industry.

New recipes, revised processes, material tests, software changes, and failed attempts may all be worth documenting. Qualification still depends on the facts.

The examples below are illustrative. They describe common business activities that may involve potential R&D. Whether specific activities qualify for the R&D tax credit depends on the facts and circumstances of each case and must be determined by a qualified CPA or tax advisor.

Industry index

Manufacturing

What the business thinks it is

Trying to reduce defects, improve throughput, test new equipment settings, improve consistency, or test alternate materials in production lines.

What might actually be R&D

Process improvement, resolving technical uncertainty about materials or methods, systematic experimentation to improve reliability, quality, or performance of a manufacturing process.

Records worth saving

·Project notes
·Test results
·Failed attempts
·Before/after metrics
·Equipment logs
·Photos/videos
·Payroll/labor time
·Invoices

CPA review note: A CPA can evaluate whether specific process improvements involved technical uncertainty and a process of experimentation that may support an R&D credit claim.

Software / SaaS

What the business thinks it is

Improving performance, reducing downtime, building new features, testing architecture changes, solving data sync issues, or scaling infrastructure.

What might actually be R&D

Software development involving technical uncertainty, performance or reliability improvement through experimentation, new algorithm development, or architectural problem-solving.

Records worth saving

·Sprint logs
·Commit history
·Architecture diagrams
·Performance benchmarks
·Bug reports
·Design docs
·Developer time tracking
·Meeting notes

CPA review note: Software development frequently involves qualifying activities, but routine maintenance and cosmetic changes typically do not. A CPA can help distinguish qualifying work.

Food & Beverage

What the business thinks it is

Testing new recipes, shelf-stability approaches, texture improvements, packaging solutions, or production consistency at scale.

What might actually be R&D

Formula development, process testing under technical uncertainty, quality and reliability improvement through systematic experimentation with ingredients or methods.

Records worth saving

·Recipe iterations
·Batch test logs
·Shelf-life data
·Lab results
·Ingredient invoices
·Production photos
·Supplier communications
·Prototype records

CPA review note: Not every recipe change is R&D. The key is whether the business faced technical uncertainty about achieving a specific functional result and used a process of experimentation.

Construction / Trades / Fabrication

What the business thinks it is

Testing installation methods, custom assemblies, new materials, workflow improvements, or jobsite process innovations to improve efficiency or structural performance.

What might actually be R&D

Technical process improvement or custom method development where the outcome was uncertain and required systematic evaluation of alternatives.

Records worth saving

·Job photos
·Engineering sketches
·Material test results
·Subcontractor invoices
·Project timelines
·Method comparisons
·Meeting notes
·Safety testing

CPA review note: Custom construction methods that involve genuine technical uncertainty may support R&D documentation. Standard applications of known methods typically do not qualify.

Events / Party / Experiential Businesses

What the business thinks it is

Developing and refining decoration systems, staging structures, custom builds, reusable installation methods, material choices, or lighting rigs across multiple events.

What might actually be R&D

Testing new installation methods, reusable build systems, structural approaches, or material durability may involve technical uncertainty—if the business is experimenting to figure out what works functionally, not just aesthetically. Ordinary decoration choices and standard design selections are not R&D. The potential is in the process of solving functional problems: how to build it, how to make it last, how to produce it efficiently.

Records worth saving

·Design mockups
·Build process documentation
·Material test notes
·Prototype photos
·Before/after comparisons
·Installation logs
·Failure records
·Cost comparisons
·Revision history

CPA review note: Ordinary decoration choices are not automatically R&D. Testing new installation methods, structural approaches, reusable build systems, material durability, or production processes could be worth documenting—if the business faced technical uncertainty and used experimentation to resolve it. A CPA should evaluate specific activities and whether they meet the four-part test.

Beauty / Cosmetics / Personal Care

What the business thinks it is

Testing formulas for consistency, texture, hold strength, scent longevity, natural preservation, batch processing, or packaging compatibility.

What might actually be R&D

Formula and process development involving technical uncertainty—testing whether specific combinations of ingredients achieve target performance characteristics.

Records worth saving

·Formula logs
·Batch records
·Stability test data
·Lab photos
·Ingredient invoices
·Before/after comparisons
·Packaging tests
·Regulatory documentation

CPA review note: Systematic formula testing that addresses technical uncertainty about achieving specific functional results may be worth documenting for CPA review.

Wood Products / Cabinetry / Millwork

What the business thinks it is

Testing new materials, finishes, wrapping processes, machining settings, quality-control systems, or production methods to improve output or reduce waste.

What might actually be R&D

Process improvement through experimentation—testing whether new techniques, materials, or equipment settings can improve quality, reduce defects, or enhance production efficiency.

Records worth saving

·Material test logs
·Finish samples
·Machine settings
·Defect tracking
·Production photos
·Cost analysis
·Process documentation
·Supplier evaluations

CPA review note: Process improvements that required testing multiple approaches to resolve technical uncertainty about achieving specific outcomes may support R&D documentation.

Logistics / Operations

What the business thinks it is

Testing routing algorithms, scheduling systems, automation workflows, warehouse processes, inventory management systems, or operational efficiency tools.

What might actually be R&D

Software and process experimentation to improve operational performance—developing new methods to solve routing, scheduling, or efficiency problems through systematic testing.

Records worth saving

·System logs
·Performance data
·Routing comparisons
·Process maps
·Software documentation
·Before/after metrics
·Meeting notes
·Implementation records

CPA review note: Operational improvements that involve developing or testing new technical approaches—rather than simply configuring existing tools—may be worth reviewing with a CPA.

The key question for any potential R&D activity

Did the business face technical uncertainty about how to achieve a specific result, and did it use a process of experimentation to evaluate alternatives and resolve that uncertainty?

If yes, the activity and its supporting records may be worth discussing with a qualified CPA or tax advisor. These examples do not determine eligibility; the four-part test and the specific facts do.

Document the work while the details are still fresh.

Don't wait until tax season. Build organized records throughout the year so your CPA has what they need.
