AI Automation/Accounting

Automate Your Accounting Department with Custom AI

The typical cost for Syntora to build an AI automation system for a small business accounting department is determined by the scope of documents and business rules involved. An initial engineering engagement for focused automation usually ranges from 2 to 4 weeks, delivering a custom system designed to replace manual data entry and recurring software fees.

Syntora helps small business accounting departments automate document processing tasks. The approach involves building custom AI systems using tools like Claude API and FastAPI to extract and validate data, aiming to reduce manual entry and replace recurring software fees.

The timeline and investment depend on the number of distinct document types you process (such as invoices, receipts, or purchase orders) and the complexity of your existing approval workflows. Syntora's engagement would focus on understanding your specific needs to design and implement a solution tailored to your operational requirements.

The Problem

What Problem Does This Solve?

Many accounting departments start with a subscription to an OCR service like Nanonets or Rossum. While these tools extract text, they struggle with non-standard invoice formats from smaller vendors. This forces a bookkeeper to manually verify every single line item, correcting errors like 'l-beam' being read as '1-beam'. The OCR only handles 60% of the work, but you pay for 100% of the processing.

Next, they try dedicated AP platforms like Bill.com. These platforms solve the payment workflow but introduce their own data silos and high per-transaction fees. Getting invoice data back into your ERP or project management tool requires another fragile integration. A 20-person agency paying $79/month plus transaction fees still spends hours exporting CSVs to match project costs in their system.

These off-the-shelf tools fail because they treat accounting as a generic workflow. They cannot handle industry-specific logic, like a construction company needing to match a supplier invoice against a purchase order and a specific job number before approval. The rigid rulesets mean exceptions always require manual intervention, which is where all the time is lost.

Our Approach

How Would Syntora Approach This?

Syntora's approach would start by integrating with your document sources, whether that's an email inbox, a shared drive, or an existing API. Using the Claude API, we would design a classification and data extraction pipeline in Python. This model would be trained on a small set of your specific documents, typically 20-30 examples, enabling it to accurately identify key fields like 'Invoice Number' and 'Due Date' regardless of variations in layout. Scans would be processed at a minimum of 300 DPI to ensure accurate character recognition.

The core of the system would be a FastAPI service, orchestrating the entire workflow. After Claude extracts the data into a structured JSON object, this service would validate it against your specific business rules. For example, the system could cross-reference extracted purchase order numbers against your existing inventory database, flagging any mismatches or missing information for review in a designated communication channel, while valid documents proceed automatically. Syntora has experience building document processing pipelines using Claude API for sensitive financial documents, and this pattern of data validation and conditional routing would be applied to your accounting documents.

The FastAPI service would be deployed as a serverless function on AWS Lambda. This architecture is event-driven, meaning it only runs when a document arrives, resulting in very low operational costs. The system would then write the extracted and validated data directly to QuickBooks Online or your ERP via its native API. Syntora would configure structured logging with structlog and establish alerts for any processing failures.

As deliverables, you would receive the complete Python source code in your private GitHub repository, along with a runbook explaining how to update vendor-specific rules or system configurations. Syntora's engagement focuses on delivering a maintainable and auditable system you own.

Why It Matters

Key Benefits

01

From Manual Entry to 8-Second Review

Reduce per-invoice processing time by over 95%. Your team shifts from tedious data entry to high-value review of flagged exceptions.

02

Pay Once, Own It Forever

A single fixed-price project replaces monthly per-user SaaS fees. You receive the full Python source code and can modify it as your business grows.

03

Your Code, Your GitHub Repo

We deliver the complete, production-ready codebase to your GitHub account. No vendor lock-in, no black boxes, no proprietary platforms.

04

Alerts For Failures, Not Successes

We configure alerts in Slack or email that trigger only when an invoice fails validation. No more sifting through dashboards to find problems.

05

Connects Directly to Your ERP

We use official APIs to integrate with QuickBooks, NetSuite, or industry-specific platforms. Data syncs instantly without manual CSV uploads.

How We Deliver

The Process

01

Week 1: Scoping and Access

You provide 20-30 sample documents and read-only access to your accounting software. We map your current workflow and define the precise business rules for automation.

02

Week 2: Core Pipeline Build

We build the extraction and validation logic using the Claude API and FastAPI. You receive a demo link to test the system with your own sample documents.
