FlyFin vs Keeper vs Decimal — Which AI Accounting Tool Wins in 2026?
FlyFin, Keeper, and Decimal are three of the most talked-about AI accounting tools for freelancers and self-employed professionals. We put all three head to head in 2026 to find out which one actually delivers the best results — and which type of user each one is right for.
If you are a freelancer, independent contractor, or self-employed professional trying to figure out which AI accounting tool is right for you, you have probably come across FlyFin, Keeper, and Decimal. All three promise to automate your bookkeeping, find your deductions, and take the pain out of tax season. All three use AI as a core part of their value proposition. And all three target roughly the same audience.
But they are not the same tool. Each one approaches the problem differently and is better suited to different types of users and financial situations. This comparison breaks down exactly how each one works, what it costs, where it excels, and where it falls short — so you can make the right choice for your specific situation without having to trial all three yourself.
How We Compared These Tools
We evaluated FlyFin, Keeper, and Decimal across six criteria: ease of setup, quality of AI expense categorization and deduction identification, tax preparation capabilities, access to human CPAs, pricing transparency, and overall value for freelancers and self-employed professionals at different income levels and complexity levels.
The Tools — What Each One Actually Does
FlyFin — AI Tax Tool With CPA Access
FlyFin connects to your bank and credit card accounts and uses AI to scan every transaction, automatically identify deductible business expenses, and categorize them by deduction type. It then prepares your tax return based on those categorized expenses and gives you access to a CPA to review and file. The combination of AI automation for the data work and human CPA oversight for the tax judgment is FlyFin’s core value proposition.
FlyFin Strengths
✅ Best AI deduction identification — scans every transaction automatically
✅ CPA access included — human review before filing
✅ Handles complex self-employment tax situations well
✅ Year-round deduction tracking not just at tax time
FlyFin Weaknesses
❌ Primarily focused on tax preparation — limited ongoing bookkeeping features
❌ Less useful for businesses with complex financial structures
❌ CPA access varies by plan tier
Keeper — AI Bookkeeping and Tax App for Freelancers
Keeper positions itself as a year-round bookkeeping and tax app rather than just a tax preparation tool. It connects to your financial accounts, categorizes transactions with AI, tracks your deductions month by month, and prepares your tax return at year end. The messaging app interface — where a tax assistant communicates with you via chat to clarify expenses and answer questions — makes the experience feel more personal and less like software. Keeper also includes a tax filing feature that handles both federal and state returns.
Keeper Strengths
✅ Year-round bookkeeping — not just tax season
✅ Conversational interface makes expense review accessible
✅ Includes both federal and state tax filing
✅ Most affordable option on this list
Keeper Weaknesses
❌ No dedicated CPA assigned — tax assistant is not a licensed CPA review
❌ Less suited for complex business structures or high-income freelancers
❌ Limited reporting features compared to more robust accounting platforms
Decimal — AI-Powered Accounting Service for Small Businesses
Decimal is different from FlyFin and Keeper in a fundamental way — it is a managed accounting service rather than a DIY software tool. You connect your financial accounts, Decimal’s AI processes and categorizes everything, and a dedicated accounting team handles your books month to month. You get a real human accountant assigned to your account who knows your business, produces monthly financial reports, and is available to answer questions. For small business owners who want to completely hand off their bookkeeping and get professional-grade financial reporting, Decimal is the most comprehensive option on this list.
Decimal Strengths
✅ Dedicated human accountant assigned to your business
✅ Monthly financial reports — profit and loss, balance sheet, cash flow
✅ Handles more complex business structures than FlyFin or Keeper
✅ Full-service — completely hands off for the business owner
Decimal Weaknesses
❌ Most expensive option — not suited for very early stage or low-revenue businesses
❌ Tax preparation is an add-on — bookkeeping is the core service
❌ Less DIY — requires trusting a third party with your financials

Who Should Use Each Tool
Choose FlyFin if: You are a freelancer, 1099 contractor, or self-employed professional with a moderate to complex tax situation and you want the strongest AI deduction finding combined with CPA review before filing. FlyFin delivers the most thorough automated deduction identification of the three tools and the CPA access gives you confidence that nothing gets missed before the return goes to the IRS.
Choose Keeper if: You are a solo freelancer or independent contractor with a relatively straightforward financial situation and you want the most affordable year-round bookkeeping and tax tool. Keeper’s conversational interface and low price point make it the most accessible entry point into AI-powered accounting for freelancers who are just getting started taking their finances seriously.
Choose Decimal if: You run a small business with employees, multiple revenue streams, or financial complexity that exceeds what a DIY tool handles well — and you want to completely hand off bookkeeping to a professional team that uses AI to keep costs reasonable. Decimal is the right choice when your business has grown to the point where you need professional-grade financial reporting and a real accountant who knows your business.
Final Verdict — Which One Wins?
There is no single winner because these tools serve different needs. But here is the honest breakdown for the most common situations.
For the typical freelancer or 1099 contractor who wants the best combination of AI deduction finding and CPA oversight — FlyFin wins. The deduction identification is the strongest of the three and the CPA review before filing is worth the price difference over Keeper.
For the freelancer who wants the most affordable year-round tool and has a simple financial situation — Keeper wins on value. At $20 per month it is the lowest barrier to getting your finances organized with AI assistance.
For the small business owner who wants professional accounting without the cost of a traditional CPA firm — Decimal wins on service quality. The dedicated accountant and comprehensive monthly reporting is a level of financial management that FlyFin and Keeper do not attempt to provide.
