Syntora builds custom AI automation for accounting firms to reduce manual audit work. The systems use Python and the Claude API to automate compliance checks, cutting analysis time from hours to minutes. Syntora has direct experience building core accounting systems with a PostgreSQL double-entry ledger.
The cost is determined by the number of client systems to integrate with, the complexity of compliance rules, and the format of source documents. Syntora has built core accounting automation, including a PostgreSQL double-entry ledger with Plaid integration. For your firm, we would extend this pattern to automate specific audit tests, connecting to client ERPs and document stores to analyze evidence automatically.
Why Do Accounting Firms Waste Hours on Manual Audit Sampling?
Most accounting firms use platforms like AuditBoard or Workiva to manage audit workflows. These tools are excellent for documentation and control tracking but do not automate the evidence analysis itself. An auditor still manually samples transactions, pulls supporting documents from a separate system, and visually confirms details. The platform provides the checklist, but the tedious, error-prone checking remains a manual task that consumes hundreds of billable hours.
For example, consider substantive testing on accounts payable for one of the 75 annual audits. An associate exports a transaction list from the client’s NetSuite instance into Excel. They spend an hour filtering and sorting to select a random sample of 60 invoices. For each one, they must locate the corresponding purchase order and receiving report in a SharePoint folder, open all three documents, and manually verify that the amounts, dates, and vendor details match. This three-way match process takes 8-10 hours per audit and is repeated for every client.
The structural problem is that audit management platforms are not data execution engines. They are designed to store evidence, not to connect to disparate data sources and run analyses. Using Excel macros or scripts is a common workaround, but these are brittle. A script written for one client's data export breaks when the next client has a slightly different column format, forcing the auditor back to manual work. This approach lacks auditable logs, robust error handling, and cannot scale across the firm's client base.
How Syntora Builds Custom AI for Automated Audit Testing
The engagement starts with mapping your firm's specific audit methodology. We identify the 3-5 most time-consuming compliance checks, such as revenue recognition testing or inventory counts, to define the initial scope. You receive a technical plan detailing the data sources, the specific tests to be automated, and the expected outputs before any code is written.
The core of the system would be a Python service using the Claude API for intelligent document analysis and pandas for data manipulation. Deployed on AWS Lambda, this service can securely process thousands of documents or transactions in parallel. For instance, it could connect to a client's SharePoint via the Microsoft Graph API, ingest a sample of 1,000 invoices, and perform a three-way match against purchase orders in under 5 minutes. All operations and results are logged in a Supabase (PostgreSQL) database, creating a complete, auditable trail of every test performed.
The delivered system is a simple web interface accessible only to your auditors. They can select a client, choose a compliance test, and upload the necessary data exports or point the system to a document folder. The system returns a clear report detailing passes, failures, and specific exceptions within minutes. This report can be exported and attached directly into your existing AuditBoard or Workiva workpapers, augmenting your primary platform with powerful, automated testing capabilities.
| Manual Audit Sampling | Syntora's Automated Testing |
|---|---|
| 8-10 hours per client for substantive testing | Under 15 minutes to run and review results |
| Sample size limited by auditor time (e.g., 60 transactions) | Test 100% of transactions or a sample of 5,000+ |
| High risk of human error in data transfer and review | Zero data entry errors with auditable, logged results |
What Are the Key Benefits?
One Engineer, No Handoffs
The person on your discovery call is the engineer who writes the Python code for your system. There are no project managers or communication relays, ensuring your requirements are implemented directly.
You Own the Code and Infrastructure
You receive the full source code in your company's GitHub and the system runs in your own AWS account. There is no vendor lock-in, no per-seat licensing, and no dependence on Syntora to operate.
A Realistic 6 to 10-Week Timeline
The initial build for the top 3 automated compliance checks is typically delivered in 6 to 10 weeks. This timeline is fixed after a data and process audit in the first week.
Transparent Post-Launch Support
An optional monthly retainer provides ongoing monitoring, updates for new compliance rules, and direct support from the engineer who built the system. There are no surprise bills.
Grounded in Accounting Principles
We built our own accounting system, including a double-entry ledger and bank transaction categorization. We understand the fundamentals behind the audit procedures you need to automate.
What Does the Process Look Like?
Discovery & Scoping
A 30-minute call to review your current audit workflows and identify the most painful manual processes. You receive a written proposal within 48 hours outlining the first 2-3 automated tests to be built.
Process Mapping & Architecture
You provide sanitized sample data and walk through your current manual checking process. Syntora designs the technical architecture and data flow, which you approve before the build begins.
Build & Weekly Demos
You see working software in weekly demos. By week 4, you can test the system with your own sanitized data to provide feedback on the reporting and user interface.
Handoff & Training
You receive the complete source code, a deployment runbook, and a training session for your audit team. Syntora provides 30 days of included post-launch monitoring and support.
Frequently Asked Questions
- What factors determine the final cost of the project?
- The primary factors are the number and type of client systems we need to pull data from, the format of the source documents (e.g., structured CSV files vs. scanned PDFs), and the complexity of the compliance logic for each test. A project focused on structured data from a single ERP is a smaller scope than one requiring OCR and analysis of documents from multiple sources.
- What can accelerate or slow down the 6 to 10-week timeline?
- The timeline is fastest when your team can provide prompt access to sanitized sample data and has a designated auditor available for questions. Delays typically arise from waiting for access to client systems or from significant changes in the compliance requirements mid-project. A clear, stable scope defined upfront ensures the fastest delivery.
- What happens after the system is handed off?
- You have full ownership of the code and infrastructure. Syntora offers an optional monthly support plan that covers monitoring, bug fixes, and updates for new compliance rules. Alternatively, you can have an internal developer or another vendor take over maintenance using the provided source code and documentation. You are never locked in.
- How do you handle sensitive client financial data?
- The entire system is built and deployed within your company's own secure AWS cloud account. Syntora never has access to or stores your clients' production data on any Syntora-owned systems. Your team controls all access credentials and security policies, ensuring the data remains within your firm's security perimeter.
- Why hire Syntora instead of a larger consulting firm?
- Large firms add layers of project managers and sales staff, which increases cost and slows down communication. With Syntora, you work directly with a single senior engineer from the first call to the final code handoff. This direct model is more efficient and ensures that the person who understands your business problem is the one building the solution.
- What does our firm need to provide for the project?
- You need to provide access to sanitized, representative data samples from your clients. You also need to designate one point of contact, typically a senior auditor or manager, who can commit 1-2 hours per week to answer questions about your current process and provide feedback during the weekly demos.
