Key Takeaways

  • Automate accounting client checklists with a custom portal that tracks document uploads and sends reminders.
  • The system integrates directly with practice management software like Karbon or TaxDome to create and assign tasks.
  • A central dashboard provides a real-time view of every client's onboarding status for all 10 team members.
  • Reduce onboarding time from an average of 14 days to under 3 days by eliminating manual follow-up.

Syntora builds custom automation for accounting firms to reduce client onboarding time. One system for a 10-person firm would use a custom portal and AI validation to cut document collection cycles from 14 days to under 3. Syntora's approach integrates with existing practice management software using Python and AWS Lambda.

The complexity depends on your current software stack and the number of document types you handle. A firm using Karbon with 15 standard document types is a different scope than one using manual spreadsheets. We built our own accounting automation system with Plaid and Stripe integrations, so we understand the data models and compliance needs of financial workflows.

The Problem

Why Do Growing Accounting Firms Struggle with Client Document Collection?

Many growing firms use practice management tools like Karbon, TaxDome, or Canopy. These are great for internal task management but their client portals are often rigid. They offer a generic checklist but cannot enforce conditional logic. For example, if a client selects "S-Corp" on an intake form, the system cannot automatically add "Form 2553" and "Bylaws" to their specific checklist. Your team has to manually update the checklist for every S-Corp client.

Consider a 10-person firm onboarding a new business client. The process starts with an email containing a link to the portal. The client uploads their P&L but forgets the bank statements. The portal shows the checklist as "in progress," but it doesn't specify which document is missing. A junior accountant must log in, compare uploads to the master list, and then manually email the client. This back-and-forth happens for 7 out of 10 new clients, delaying kickoff by an average of 5-7 business days.

The core problem is that off-the-shelf portals are built for one-size-fits-all workflows. Their data model is fixed. You cannot create rules like "IF client_type is 'Real Estate' AND entity_type is 'LLC', THEN require 'Operating Agreement'." These platforms are designed to sell seats and generic features, not to adapt to the specific document matrix of your firm's service lines. They treat document collection as a simple list, not a dynamic, logic-driven process.

Our Approach

How Syntora Builds a Custom Portal to Automate Accounting Task Management

Syntora starts by mapping your entire client onboarding workflow, from the moment a proposal is signed. We document every document type, every task, and every piece of conditional logic for each service line you offer. For our own accounting operations, we built a 12-tab admin dashboard to manage different financial workflows. A similar discovery process for your firm produces a detailed schema of your client data and document requirements.

The solution would be a secure client portal built with FastAPI and a Supabase PostgreSQL database for data storage. Your version would connect to your practice management software's API to sync client data. We would use the Claude API to read uploaded documents, validate their contents (e.g., confirming a PDF is a W-9 and not a random invoice), and extract key information. This AI-driven validation can reduce manual review time by over 80%.

You receive a custom-branded client portal where clients see dynamic checklists tailored to their specific needs. For your team, you get a central dashboard showing the real-time status of every onboarding client, with automated task creation in your existing PM tool. The system runs on AWS Lambda, costing under $50 per month to operate. You get the full source code and a runbook for maintenance. We built our own accounting system on PostgreSQL; we understand the reliability needed for financial data.
