02 / THE BUSINESS CHALLENGE

When tools are disconnected, tax season becomes an unmanageable crisis.

Tax professionals work under unforgiving filing deadlines while handling highly sensitive personal and financial information. A single engagement may involve gathering wage statements, reconciling supporting schedules, requesting missing evidence, coordinating reviews, obtaining signatures, and collecting fees.

Insecure Document Leakage

Taxpayers send sensitive SSNs and 1099s through unencrypted email attachments or consumer messaging apps.

40% Time Lost to Administrative Chasing

Preparers spend hours manual-checking whether Form 8879 e-signatures were signed or if retained deposits cleared.

Fragmented Firm-Wide Visibility

Partners lack unified real-time reporting on staff workload, overdue returns, and uncollected invoice amounts.

03 / THE SOLUTION ARCHITECTURE
ONE UNIFIED ENGINE · THREE PURPOSE-BUILT EXPERIENCES

Architected for how tax practices actually operate.

The proposed solution combines an administrative console, staff workspace, and secure client-facing portal. Firm administrators configure their brand, invite employees, establish departments, assign permissions, and select subscription capabilities.

ROLE 01: MANAGING PARTNER

Admin Console

Complete oversight of firm-wide performance, revenue forecasting, subscription tiers, staff access permissions, compliance audit trails, and multi-office routing.

ROLE 02: TAX PREPARER & CPA

Staff Workspace

Action-driven daily command center featuring personalized Kanban queues, deadline monitors, intake form trackers, document review screens, and quick e-sign triggers.

ROLE 03: TAXPAYER CLIENT

Client Portal

A distraction-free, branded experience for individual taxpayers and business owners. Guided document checklists, mobile uploads, e-signing, and one-click invoice settling.

When a client uploads a document in the Portal, the Preparer’s Kanban task shifts to “In Review” instantly, and Admin compliance logs register the timestamp.

Instantly toggle between historical filings to compare previous Schedule C deductions or retrieve prior-year return PDFs without switching databases.

07 / E-SIGNATURE INTEGRATION
POWERED BY SIGNWELL API PROTOCOL

Tax returns cannot be filed until Form 8879 and engagement agreements are executed. By integrating SignWell directly within the SeQwens workflow, taxpayers sign on mobile or desktop
without creating external software accounts.

Legally Binding Cryptographic Hash

Each signed document generates a SHA-256 certificate containing signer IP address, timestamp, and audit trail.

Automated Status Progression

Upon execution by both spouses on married filing jointly returns, SeQwens instantly transitions the task state to "Approved for Filing".

Zero-Drop Signer Completion Rate

SMS notifications and smart deadline reminders reduce unsigned engagement letters from 12 days to under 18 hours.

08 / Workflow Automation and Team Collaboration
OPERATIONAL ORCHESTRATION & TASK PIPELINES

From chaos to cadence: Interactive Kanban engineered for tax sprints.

Administrators can define reusable templates for activities such as Form 1040 preparation, new-client onboarding, and entity formation. Tasks can include owners, priorities, deadlines, attached documents, and dependencies. Events such as a document upload, task completion, or received payment can initiate the next action.

Intake Trigger Queue

Clients enter when tax engagement letter is executed. Auto-dispatches onboarding questionnaire and document portal credentials.

Preparer Active Work

Permanent PDF copies encrypted into the 7-year audit retention vault with instant client download availability.

09 / PAYMENTS & SUBSCRIPTION COMMERCE
SEAMLESS CASH-FLOW ACCELERATION VIA STRIPE

End the invoice chase. Connect tax delivery directly to card payments.

Accounting firms notoriously suffer from 60+ day Accounts Receivable cycles. SeQwens integrates Stripe Connect to allow firms to invoice per preparation, collect upfront retainers, or bill recurring advisory subscriptions.
INVOICING CAPABILITIES
STRIPE POWERED

Instant In-Portal Payment Gateways

Taxpayers settle invoices via Credit Card, Debit, Apple Pay, or ACH transfer directly in their portal.

Automated Document Release Locks

Optional setting prevents final signed 1040 copy downloads until outstanding invoices reflect "Paid".

Tiered SaaS Subscription Management

Solo ($49), Team ($149), and Professional ($299) tiers let firms scale user seats and storage effortlessly.

10 / SECURITY, GOVERNANCE & SCALE
RIGOROUS DATA ISOLATION & COMPLIANCE TARGETS

Bank-grade encryption guarding client financial sovereignty.

Because tax engagements involve sensitive identifiers and financial documents, security must be designed into the operating model.

ENCRYPTION PROTOCOL

AES-256 + TLS 1.3

Rest and transit encryption across all document vaults.

SESSION INTEGRITY

Optional 2FA & MFA

Automated session timeout and suspicious IP blocking.

DATA RETENTION
