Build an AI System for Client Intake and Document Sharing
Key features are automated data extraction from intake forms and a secure, client-specific portal for document sharing. The system must include a complete audit trail for compliance and integrate directly with your practice management software.
Key Takeaways
- Key AI features are automated data extraction from forms and secure, client-specific document portals with audit trails.
- The system must integrate directly with your practice management software, not just export a CSV file.
- Secure document sharing requires signed URLs and IAM policies, not just a password-protected folder.
- Automated extraction can reduce manual data entry from 15 minutes per client to under 60 seconds.
Syntora has experience building accounting automation systems that use a PostgreSQL double-entry ledger. This expertise in financial data integrity allows Syntora to build secure client onboarding portals for accounting firms. The delivered systems can reduce manual data entry by over 90%.
The complexity of the build depends on the variety of documents you handle and the number of systems you need to connect. We built our own internal accounting system with a 12-tab dashboard and a PostgreSQL double-entry ledger. That experience with financial data integrity directly applies to building a system that tracks client data with the same level of care.
Why Do Accounting Firms Still Manually Onboard New Clients?
Many accounting firms rely on a patchwork of tools like ShareFile, Liscio, and general-purpose form builders. ShareFile and Liscio provide a secure portal for file exchange, but they treat documents as black boxes. An accountant still has to download a W-2 and manually type the data into CCH Axcess or UltraTax. The secure sharing is present, but the automation is completely missing.
Consider the typical onboarding process for a new client. Your firm emails a 10-page PDF organizer. The client prints it, fills it out, scans it, and emails it back along with a dozen other attachments like prior year returns and 1099s. An admin then spends 30-45 minutes downloading everything, creating a folder structure, renaming files, and transcribing data from the organizer into your tax software. If a K-1 is missing, an insecure email chain begins.
Workflow tools like Karbon try to solve this with checklists and basic forms, but they cannot perform data extraction. The structural problem is that these tools are either secure file vaults or task managers. They are not designed to be data intake systems. Their architecture is built around files or tasks, not the structured data contained within the files. To solve this, you need a system built from the ground up to connect document analysis with your core practice management database.
How Syntora Builds an Integrated Client Onboarding and Document System
The first step is a discovery process to map every data point your firm needs for a new client. We audit the specific documents you collect, like W-2s, 1099-DIVs, and broker statements, and identify the exact fields to extract. We then map these fields to your downstream systems, whether that's CCH Axcess or QuickBooks. This audit produces a precise data schema and integration plan before any code is written.
The technical approach uses a FastAPI service to handle client uploads and a Claude API integration to perform the data extraction from PDFs. We use Supabase for its PostgreSQL database and user authentication, which allows us to create isolated, secure portals for each client. Documents are stored in AWS S3 with fine-grained IAM policies, and access is granted via temporary pre-signed URLs, which is far more secure than a standard shared link. The system creates a complete audit log for every action.
The delivered system is a simple web portal for your clients and an admin dashboard for your team. Clients upload documents and see a checklist of what is still needed. Your team sees extracted, validated data ready to be synced to your practice management software with a single click. The process reduces an hour of fragmented work into a 5-minute review.
| Manual Onboarding Workflow | Syntora Automated System |
|---|---|
| 15-30 minutes of manual data entry per new client. | Data extracted from documents in under 60 seconds. |
| Documents sent via unsecured email attachments. | Isolated client portal with access logs and IAM policies. |
| 5-10% error rate from manual data transcription. | Under 1% error rate with automated validation checks. |
What Are the Key Benefits?
One Engineer, End-to-End
The engineer on your discovery call is the one who writes the code. No project managers or handoffs. You have direct communication with the builder from start to finish.
You Own All Code and Infrastructure
The entire system is deployed in your AWS account. You receive the full source code in your GitHub repository and a technical runbook. There is no vendor lock-in.
Build Cycle of 4-6 Weeks
A typical client onboarding system, from discovery to go-live, takes between 4 and 6 weeks. The initial data and workflow audit determines the precise timeline before the build begins.
Transparent Post-Launch Support
After deployment, you can choose a flat monthly support plan for monitoring, maintenance, and system updates. No per-user fees, no hidden charges, and no long-term contracts.
Deep Accounting Data Experience
Syntora built a complete double-entry ledger system using PostgreSQL for its own operations. We understand the high standard for data integrity and auditability required in accounting.
What Does the Process Look Like?
Discovery Call
A 30-minute call to map your current client intake workflow and identify bottlenecks. You receive a scope document within 48 hours outlining the proposed system, timeline, and fixed price.
System Architecture & Data Mapping
We finalize the exact data fields, document types, and integration points with your existing software. You approve the technical architecture and data schema before any code is written.
Iterative Build with Weekly Demos
You get access to a staging environment within the first 2 weeks. Weekly calls demonstrate progress and gather feedback, ensuring the final system matches your firm's exact workflow.
Deployment and Handoff
The system is deployed to your cloud infrastructure. You receive the complete source code, a technical runbook for maintenance, and focused training for your team.
Frequently Asked Questions
- What determines the cost of a custom onboarding system?
- The cost is determined by three main factors: the number of different document types the AI needs to learn to parse, the number of external software systems to integrate with (e.g., practice management, billing), and the complexity of your firm's user permission rules. A discovery call produces a fixed-price quote based on a clearly defined scope.
- How long does this take to build?
- A typical build takes 4 to 6 weeks from kickoff to deployment. The main variable is the quality and accessibility of the APIs for any software we need to integrate with. The initial discovery and architecture phase provides a much more precise timeline before you commit to the full build, reducing uncertainty for your firm.
- What happens if something breaks after launch?
- You own the source code and the technical runbook, giving you full control. For ongoing peace of mind, Syntora offers a flat monthly support plan that covers system monitoring, bug fixes, and maintenance. This gives you direct access to the engineer who built the system, ensuring fast and effective resolutions.
- How do you ensure our clients' financial data is secure?
- Security is the primary design constraint. We use AWS infrastructure with strict IAM policies, per-client data isolation in a PostgreSQL database, and end-to-end encryption. Documents are accessed via temporary, expiring signed URLs, not public links. The system is architected on the principle of least privilege, ensuring no data is exposed unnecessarily.
- Why hire Syntora instead of a larger agency or a freelancer?
- Syntora is a single senior engineer who manages the entire project. Unlike a large agency, there are no handoffs between sales, project managers, and junior developers. Unlike a typical freelancer, Syntora specializes in building and deploying production-grade AI systems, not just writing scripts. You get one expert point of contact from start to finish.
- What do we need to provide to get started?
- You need to provide access to one person at your firm who deeply understands your current client onboarding process. We will also need anonymized sample documents for the AI to train on and read-only API keys for any software we need to connect with during the build phase. Your team's time commitment is typically one hour per week for demos and feedback.
