Digits vs. Puzzle: Which AI Accounting Platform Is Actually Built for Firms?

Update: Accrual has acquired Puzzle.

On September 2, 2026, Puzzle announced its acquisition by Accrual. Read the announcement →

Digits and Puzzle both call themselves AI-native accounting platforms. The difference is what sits underneath that label — how the AI actually works, whether the company publishes proof, and whether the platform measurably reduces bookkeeping work or simply layers AI into existing workflows.

What is Digits?

Digits is the world's first AI-native accounting platform, built for accounting firms and the businesses they serve. At its core is the Agentic General Ledger™ (AGL®), which uses purpose-built accounting AI to continuously categorize transactions, maintain reconciliations, verify work, and keep the books current.

Digits is AI-native, ledger-native, and agentic. Its AI works directly inside the general ledger, with access to the financial data and accounting context it needs to move routine work forward. When judgment is needed, it surfaces the exception for an accountant.

Digits spent six years developing proprietary, domain-specific accounting models trained on 180 million transactions representing nearly $1 trillion in real financial activity. And it publishes the results: in its 2026 benchmark, Digits AGL achieved 97.8% transaction-categorization accuracy, outperforming every frontier AI model tested.

What is Puzzle?

In September 2026, Accrual announced an agreement to acquire Puzzle’s accounting-firm technology and business. Puzzle will continue operating independently for startups and small businesses, while its firm-focused technology and team are expected to become part of Accrual following the close.

Today, Accrual’s platform is focused primarily on automating individual tax preparation for accounting firms. The planned addition of Puzzle expands that direction into client accounting services.

Puzzle is an AI-assisted accounting platform built primarily for startups and small businesses. It has also offered tools for accounting firms serving startup clients.

Puzzle describes its approach as “governed AI.” The software helps prepare accounting work while humans remain responsible for review and approval. Its categorization workflow uses rules to process transactions that match established criteria, while transactions outside those rules require human intervention.

What is the difference between Digits and Puzzle?

Digits is the world's first AI-native accounting platform, built for firms, informed by real accounting work, and designed to reduce the need for a close entirely instead of layering AI onto the workflows that make a close necessary in the first place.

Puzzle was built primarily for startups and small businesses, with tools for accounting firms serving startup clients. Its governed-AI approach uses AI to prepare accounting work while keeping humans responsible for review and approval.

The core difference is how much work the software completes on its own. Puzzle helps teams work through the close. Digits is designed to keep the books continuously current, reducing the work that piles up at month-end.

In September 2026, Accrual announced an agreement to acquire Puzzle’s accounting-firm technology and business. Digits remains an independent platform built for accounting firms.

Does Digits compete with accounting firms?

No. Digits does not compete with accounting firms, nor does it operate as one.

Digits is a software platform built for accounting firms and small businesses.

During its research and development phase, Digits operated an internal accounting practice. That practice served roughly 150 real clients across industries and stages. The goal was simple: run the software under real-world conditions in a real firm environment and get direct, unfiltered feedback from the people it was being built for: accountants.

Every workflow, edge case, and failure showed up there first. The product was shaped inside the work itself, not around it.

When the system reached maturity, that practice was intentionally transitioned to a Digits partner firm. More than 100 clients were transitioned, expanding that firm's portfolio while maintaining continuity for the clients, who stayed on the platform.

Digits did not build its software by guessing what firms needed. It built the system inside real accounting work, under real pressure, with real clients. That is why the product feels different. No other accounting platform can say that.

Today, Digits supports firms through its partner program and routes service demand through the Digits Accountant Directory. Hundreds of businesses have already been connected with dozens of participating firms.

Digits used real accounting work to build better software, then turned that same platform into a growth engine for firms.

How does Digits' AI work differently from Puzzle's?

Puzzle describes its approach as “Governed Automation,” where AI handles preparation while accountants remain in control of review, judgment, and approval. Digits is agentic, AI-native, and ledger-native, with AI at the core of the ledger and the workflows around it.

Those differences change the workflow from the very first transaction.

Puzzle uses rules to decide where transactions belong. When a transaction fits a rule, the system moves it forward. When it does not, the process stops, and a person has to take over. That is what "governed" means in practice: the AI helps, but the human still drives the workflow.

Digits works from a very different foundation. Its team spent six years developing proprietary, domain-specific AI models built specifically for accounting. These models are deterministic, designed to produce consistent, verifiable results rather than rely on a general-purpose LLM to generate a probable answer.

Because Digits is ledger-native, its AI works directly inside the general ledger, with access to the financial data and accounting context around each transaction. Those models were trained on 180 million transactions representing nearly $1 trillion in real financial activity, so they do not need every decision mapped out in advance. They look at the full context of a transaction, including merchant text, historical patterns, amount ranges, related activity, and the chart of accounts, then make an informed categorization decision from the start.

When Digits is confident, the work moves forward automatically. When it is not, the system routes the transaction to the accountant, learns from the answer, and gets better the next time. That is what makes Digits agentic: it takes action first, then brings humans in where judgment is needed.

That is why Digits does not depend on rules you have to build and maintain. It learns patterns from your data and from what your team confirms or corrects, then strengthens its own logic over time. Digits also learns at the client and firm levels, so the system starts strong and becomes more tailored with use.

Puzzle waits for rules. Digits moves the work.

Whose AI is more accurate: Digits or Puzzle?

Digits is the only one of the two that publicly publishes comparable AI accuracy benchmarks.

Digits publishes a product benchmark, not just an accuracy claim. Digits AGL achieved 97.8% transaction-categorization accuracy using ground truth reviewed by U.S.-based GAAP accountants, outperforming every frontier AI model tested.

The whitepaper is public: Beyond the AI Hype: Evaluating LLMs vs. Digits AGL for Accounting Tasks. Read the methodology. Check the numbers. That is what it looks like when a company is willing to be measured.

Puzzle has not published comparable benchmarks, training methodology, or evidence at that level of detail.

Digits also treats performance as something to measure continuously, not just claim once. Digits tracks transaction handling, categorization confidence, exception routing, and verification outcomes directly inside the workflow.

That creates a different standard of accountability. Digits publishes benchmark methodology, measures live system performance, and continuously validates its outputs rather than relying on marketing claims alone.

Do Digits or Puzzle back up their AI claims?

Digits backs its AI claims with published benchmarks, transparent methodology, and verification built directly into the accounting workflow. Puzzle does not publish the same level of detail publicly.

Digits goes beyond measuring transaction-categorization accuracy. The platform tracks confidence, exception handling, reconciliation, and verification as work moves through the ledger, giving firms visibility into where AI can complete the work and where human judgment is needed.

Puzzle describes its AI as governed, with humans responsible for review and approval, but has not published comparable benchmark methodology or performance measurement standards.

For firms evaluating AI accounting software, that makes Digits easier to assess on measurable performance, not just product claims.

Is Digits or Puzzle better for accounting firms?

Digits is the stronger choice for accounting firms. Digits is built around the workflows, constraints, and scale accounting firms actually deal with, helping teams automate more client work without adding manual effort at the same rate.

The comparison has also changed. In September 2026, Accrual announced an agreement to acquire Puzzle’s accounting-firm technology and business. Puzzle will continue operating independently for startups and small businesses, while its firm-focused technology and team are expected to become part of Accrual following the close.

Digits continues to build for accounting firms and the businesses they serve. It is AI-native, ledger-native, and agentic, with AI working directly inside the general ledger to move accounting work forward.

Digits categorizes transactions, maintains reconciliations, verifies its work, and keeps financials current. When judgment is needed, it surfaces the exception for an accountant instead of requiring people to review every step.

For firms, that means less repetitive bookkeeping, fewer tasks piling up at month-end, and more capacity to serve clients as the firm grows.

On September 2, 2026, Accrual announced an agreement to acquire Puzzle's accounting-firm technology and business. Accrual described the deal as being about technology, product, and talent rather than consolidating customers.

Who acquired Puzzle?

Accrual. On September 2, 2026, Accrual announced it had entered into an agreement to acquire Puzzle's accounting-firm technology and business. The transaction is expected to close in the coming weeks, subject to customary closing conditions. Financial terms were not disclosed.

What is the main difference between Digits and Puzzle?

Digits is the world's first AI-native accounting platform, built for firms, informed by real accounting work, and designed to reduce the need for a close entirely, rather than layering AI onto the workflows that make a close necessary in the first place.

Puzzle is a modern accounting platform built for startup founders and finance teams, structured around a rules-based, governed close process, and designed to make the close more manageable rather than eliminate the work that makes a close necessary in the first place.

Puzzle claims to modernize the traditional close. Digits is designed to eliminate the need for it.

Is Digits or Puzzle better for accounting firms?

Digits is the stronger choice for accounting firms. It is built around the workflows, constraints, and scale accounting firms actually deal with, helping teams automate more client work without adding manual effort at the same rate.

The comparison has also changed. In September 2026, Accrual announced an agreement to acquire Puzzle’s accounting-firm technology and business. Puzzle will continue operating independently for startups and small businesses, while its firm-focused technology and team are expected to become part of Accrual following the close.

Digits continues to build for accounting firms and the businesses they serve.

Did Digits ever compete with accounting firms?

No. Digits is a software platform built to work with accounting firms, not replace them. Early on, Digits ran an internal accounting practice for one reason: to build better accounting software. That gave the product team direct exposure to real books, real workflows, and real pressure while the system was being shaped. Once the product was ready, that practice was sold off. Today, Digits supports firms through its partner program and routes managed-service demand through certified partner firms.

Does Digits have in-house CPAs that compete with bookkeepers?

No. Digits does not operate a bookkeeping, tax, or accounting practice that competes with firms. Digits does have accountants on staff, but they work in enablement, helping firms onboard and use the platform effectively. When clients need managed services beyond the software, Digits routes that work to Digits-certified partner firms.

Is Digits an autonomous accounting platform?

No. Digits is agentic, not autonomous. The Agentic General Ledger™ handles routine bookkeeping work, then brings in an accountant when something needs human judgment. It can categorize transactions, reconcile activity, and keep the books current, but it does not try to replace the accountant. That is the difference: agentic software takes action, while autonomous software implies no human is needed.

What does "AI-governed" mean?

AI-governed means the software helps prepare the work, but a human stays in control of the decision. In Puzzle's own language, the AI drafts the work and humans approve it, with review gates, audit trails, and sign-off built into the process. Puzzle also says "nothing posts without your approval." In plain English: the AI helps, but the accountant is still the driver.

What accounting software is best for accounting firms in 2026?

Digits. It is the world's first AI-native accounting platform, built for accounting firms with practicing accountants shaping the product from day one. The Agentic General Ledger™ maintains the ledger continuously rather than accumulating work for a monthly close. The platform combines AI-native architecture, embedded verification, published benchmark performance, and workflows purpose-built for firms.

Digits is the world's first AI-native accounting platform — built for accounting firms, designed to reduce the close rather than improve it.
