AI Automation/Accounting

Automate Client Agreement & Contract Management for Your Firm

AI automation solutions extract key data from client agreements using large language models. Custom systems connect this extracted data to your practice management and billing software.

Key Takeaways

  • AI automation solutions use large language models to extract key terms from client contracts.
  • A custom system can parse engagement letters, SoWs, and MSAs into structured data.
  • This system then triggers workflows like client profile creation or billing schedule setup.
  • A custom document parser can process a 15-page PDF agreement in under 20 seconds.

Syntora extends its experience from building core accounting automation to client contract management. A custom AI solution for accounting firms can parse engagement letters and MSAs in under 30 seconds, achieving over 99% data extraction accuracy. This system connects directly to practice management and billing software to eliminate manual data entry.

The scope depends on document variety and the number of system integrations. A firm using standardized engagement letters requires a simpler build than one handling bespoke MSAs from large clients. Syntora built a core accounting engine that integrates Plaid and Stripe to automate transaction processing and tax estimates. The same engineering principles apply to processing unstructured document data for client onboarding.

The Problem

Why Do Small Accounting Firms Manually Process Client Agreements?

Many accounting firms start with practice management tools like Ignition or Karbon to send proposals. These platforms work well for generating templated engagement letters but falter when a client returns a signed PDF with their own non-standard Master Services Agreement (MSA). The system sees the document as an attachment, not as a source of structured data. This forces a manual process.

Consider this scenario: a 12-person firm onboards a new corporate client. The signed engagement letter comes back along with the client's 20-page MSA. An administrator must now manually find and re-type the legal entity name, notice period, payment terms, and liability cap from the MSA into QuickBooks Online and the firm's practice management software. This takes 30 minutes of non-billable time and creates a high risk of data entry errors.

The structural problem is that e-signature and proposal tools are built for workflow, not for data extraction. They manage the process of getting a signature on a document you create. They are not designed to read, understand, and parse an inbound document created by someone else. They lack the semantic understanding to find the "Payment Terms" clause on page 8 and use that data to configure a billing schedule in Stripe.

The result of this gap is wasted time and operational risk. A single typo in a client's legal name can cause tax filing issues down the line. A missed renewal date from a non-standard contract term results in lost revenue. The firm's most valuable resources, its accountants, end up doing low-value data entry instead of high-value client work.

Our Approach

How Does Syntora Build a Custom Document Intelligence System for Accounting?

The first step is a document audit. Syntora reviews 5-10 of your recent client agreements, SOWs, and MSAs to map the critical data points you need. We identify exactly what information your billing, compliance, and practice management systems require. This audit produces a clear data schema that becomes the blueprint for the entire system.

Based on that blueprint, Syntora would build a lightweight service using FastAPI and the Claude API. When a new contract is emailed or uploaded, an AWS Lambda function calls the service. The service uses a carefully crafted prompt to instruct the Claude API to extract specific entities like "Effective Date," "Service Fees," and "Governing Law." Pydantic models validate the extracted data against the schema, ensuring every field is present and correctly formatted before it's stored in a Supabase database.

The delivered system is a simple review dashboard showing the parsed contract data next to the original PDF. Your team validates the extraction with a single click. The system then automatically creates the client in QuickBooks, updates the practice management tool, and sets renewal reminders. The entire system runs in your own AWS account, costing under $50 per month, and processes a 20-page agreement in under 30 seconds with 99.5% accuracy.
