For Accounting Firms

Claude Cowork for Accounting
Month-end close in hours, not days.

Your firm closes books for dozens of clients every month. Journal entries, reconciliations, adjusting entries, financial statements. It's detail-sensitive work, but most of it is pattern matching. Cowork handles the repetitive parts so your team focuses on the judgment calls.

The real problem with accounting work in 2026

Your team's hours go to repetitive tasks that don't require a CPA.

Month-end close takes too long

Manual journal entries, reconciliations, and adjusting entries across multiple clients. Small firms spend 3-5 days per client closing books. It's repetitive but detail-sensitive. One missed accrual or misclassified transaction means rework, and rework means late deliverables.

Bank reconciliation is tedious busywork

Matching transactions, identifying discrepancies, tracking outstanding items. Every statement, every month, every client. It's pattern matching that still requires eyes on every line. Your staff spends hours on work that any bookkeeper could do. That's not why you hired CPAs.

Tax season buries you in document prep

Gathering supporting docs, organizing by category, preparing workpapers, formatting client-ready deliverables. The work isn't hard but the volume is crushing. During peak season, your team is sorting PDFs instead of doing the analytical work clients actually pay for.

Client deliverables look different every time

Financial statements, variance reports, board packages. Different staff produce different formatting. Clients notice the inconsistency. You've built templates, but people still deviate. The result: time spent on formatting reviews that should be spent on analysis.

How Claude Cowork solves it

Real workflows, not slide deck concepts. Here's what Cowork actually does for accounting firms.

Automated Journal Entry Drafting

Cowork reads your bank feeds, credit card statements, and transaction exports, then drafts journal entries following your chart of accounts. It categorizes transactions based on vendor patterns your firm has established, flags anything unusual for review, and formats entries ready to import into your accounting software.

Bank Reconciliation

Feed Cowork a bank statement PDF and your GL trial balance. It matches transactions, identifies timing differences, flags unreconciled items, and produces a clean reconciliation report. Set this up as a scheduled task and reconciliations run automatically when new statements arrive.

Month-End Close Workflow

Build a custom skill that walks through your firm's close checklist: review accruals, verify cutoffs, reconcile intercompany balances, prepare adjusting entries, generate financial statements. Cowork executes each step, tracks completion, and produces the close package your clients expect.

Tax Prep Document Organization

Point Cowork at a folder of client documents (W-2s, 1099s, receipts, prior year returns) and it sorts everything by category, cross-references against your tax prep checklist, flags missing items, and prepares a summary memo for the preparer. Hours of sorting done in minutes.

Client Deliverable Formatting

Cowork formats financial statements, management reports, and board packages using your firm's templates. Same fonts, same layout, same presentation, every time. Your staff focuses on the analysis. Cowork handles the formatting.

Every setup is configured for your firm's specific chart of accounts, close procedures, and tools.

What we build for your firm

Your chart of accounts, your close procedures, your templates. We configure Cowork around how your firm already operates.

Custom Skills

Skills for journal entry drafting against your specific chart of accounts, close procedures matching your firm's checklist, deliverable formatting in your templates, and tax prep workflows for your client types. Your staff runs a single command and gets output that follows your firm's exact procedures.

Plugins

Cowork includes the official /finance plugin from Anthropic for financial analysis and reporting. We configure additional plugins based on your firm's service lines, so Cowork has the right tools loaded when your team needs them.

Connectors

We connect Cowork to Microsoft 365 for email and document sharing, Slack for team communication, and your data sources via Snowflake, BigQuery, or direct file access. Cowork reads bank feeds and GL exports where your team already stores them. No switching between platforms.

Scheduled Tasks

Automated bank reconciliation when new statements arrive, weekly close progress reports, monthly client deliverable generation, and daily transaction categorization reviews. Cowork runs these on schedule and delivers results to your team's Slack channel or email.

We train your team. Remote or in-person.

Software without training is shelfware. We run hands-on training sessions where your accountants and bookkeepers practice on their actual client files: journal entry drafting, bank reconciliation, month-end close, tax prep. The workflows they'll use tomorrow.

Remote sessions work for most teams. For firms in NYC, we offer in-person training at your office. Either way, your team leaves the session knowing how to run their own workflows without us.

Frequently Asked Questions

Can Claude Cowork connect to my accounting software?
Cowork connects to data sources via MCP connectors. It can read exports from QuickBooks, Xero, and other accounting platforms through file access or database connectors like Snowflake and BigQuery. We configure the connection based on how your firm exports and stores data.
How does Cowork handle different clients with different charts of accounts?
We build separate skills for each client or client type. Each skill references the specific chart of accounts, categorization rules, and formatting preferences for that client. Your staff runs the same command but gets client-specific output.
Is Cowork accurate enough for accounting work?
Cowork drafts entries and produces reports for your review. It doesn't post to your ledger automatically. Think of it as a very fast, very consistent staff accountant who always follows your procedures and flags anything it's unsure about. You review and approve before anything goes final.
Can Cowork help during tax season specifically?
Yes. We build tax prep skills that organize client documents, cross-reference against prep checklists, flag missing items, and format workpapers. Firms using Cowork for tax season report cutting document prep time by more than half.
How long does setup take for an accounting firm?
Initial setup takes one session. We configure connectors, install relevant plugins, and build your first custom skills for the workflows that take the most time. Over two weeks, we refine based on real usage and train your team on day-to-day workflows.
