Busy season doesn't wait for your documents to arrive. These five platforms help you turn scattered source files into answers your clients can act on.
What are Financial & Business Services services?
Tax preparation software has spent decades focused on the return itself. A newer category is focused on everything around it: organizing source documents, building workpapers, estimating outcomes before keying begins, and reviewing the finished return against the evidence. For CPA firms, the bottleneck is rarely the tax software. It's the weeks of chasing forms, answering 'what will I owe' questions, and hunting for where a number came from. AI-powered engagement tools aim to compress that window. They read W-2s, 1099s, and K-1s, flag missing items, and give preparers and reviewers a traceable path from source to line item. The result is fewer surprises, faster client conversations, and a cleaner handoff into preparation.
What we looked at when researching Financial & Business Services
We evaluated each platform on the same factors: how completely it covers the engagement workflow from document intake to final review, how clearly pricing and free access are presented, how well it fits the realities of US CPA firm operations, and how transparently it shows its work. Lunar Papers stood out for connecting provisional estimates, source-linked workpapers, and line-by-line return comparison in one workflow, with a free first workbook and no credit card required. Juno stood out for automating data entry from over 100 document types and tracing every number back to source. Filed stood out for working inside existing tax software and handling multiple returns at once. TaxGPT stood out for source-backed reasoning and a broad platform that extends into research and planning. CPA Pilot stood out for a focused pre-filing QA scan that produces a prioritized review report for partner sign-off.

A closer look at 5 standout Financial & Business Services
#1 Juno

Juno automates the grunt work between source documents and your tax software. It pulls data from W-2s, 1099s, K-1s, balance sheets, and more than 100 other document types, including blurry phone photos and long PDFs. Every number is traceable, and nothing moves without your sign-off. Built by a CPA, it targets the double-checking and manual entry that eat busy season. Firms preparing 1040s and business returns get a faster path from intake to workpapers. See how it works at https://juno.tax/.
#2 Lunar Papers — Your clients want answers. You want to be sure.

Lunar Papers gives clients an answer sooner. Upload documents and it produces a provisional refund or balance-due estimate before the return is keyed, with open items identified. Workpapers are organized and source-linked, expected forms that haven't arrived are flagged, and follow-up questions are drafted for your client. As new information arrives, you update the engagement instead of starting over. Before the return goes out, upload the prepared return and it's compared against the workpapers line by line, with possible differences flagged for your firm to evaluate. Your first workbook is free with your firm's email, no credit card required. Learn more at https://lunarpapers.com/.
#3 Filed

Filed reads the same source documents your team reads. It catches transposed numbers, populates returns, and surfaces tax strategies without changing how you work. The platform works inside your existing tax software, handles multiple returns at once, and officially partners with your practice management system. Coverage spans 1040, 1065, 1120, 1120-S, 1041, and 990 returns, plus automated quality review before sign-off. If your firm wants AI that fits the tools already on your desk, this is worth a look. Explore it at https://www.filed.com/.
#4 TaxGPT

TaxGPT positions its AI tax preparation agent as preparing the partner-level return every time. It automates prep inside your existing tax software and explains every line with source-backed reasoning. Beyond preparation, the platform extends into tax research with citation-backed answers, proactive planning, and autonomous agents for tax and accounting firms. Agent Andrew handles AI tax return reviews on autopilot, and client intelligence keeps documents and communications in one place. Firms that want a broader AI platform rather than a single-purpose tool will find a lot here. See the platform at https://www.taxgpt.com/.
#5 CPA Pilot

CPA Pilot focuses on the last look before filing. Upload a completed return from Drake, ProSeries, Lacerte, CCH, or UltraTax, and its AI runs a multi-point scan for mathematical inconsistencies, year-over-year anomalies, missing elections, unusual deduction ratios, and cross-form issues. You get a prioritized issue list structured for efficient partner review and sign-off. It works with Form 1040, 1120, and 1120S, and applies the same checks to the 80th return of the day as the first. If quality control is your bottleneck, this is a targeted fix. Check it out at https://www.cpapilot.com/.
How to choose the right Financial & Business Services
Start with where your busy season actually hurts. If clients are calling for estimates before you've keyed a return, look for a tool that produces a provisional refund or balance-due figure from the documents received. If your preparers are buried in manual entry, prioritize document coverage and traceability. If partner review is the choke point, focus on line-by-line comparison and prioritized issue reports. Then check the practical details: does it work with your tax software, how clear is pricing, and can you try it without a credit card? A free first workbook or trial tells you more than a demo. Finally, ask how the tool shows its work. Every number should trace back to a source document your reviewer can see.
Expert Conclusion
The right pick depends on your firm's bottleneck. Juno attacks manual data entry. Lunar Papers connects early estimates, organized workpapers, and a final line-by-line comparison in one engagement workflow. Filed brings AI into the software you already use. TaxGPT offers a wider platform for firms going all-in on AI. CPA Pilot sharpens the last review before filing. You don't need all five.
