Outcomes
Buyer invoices, consignor settlements, and payment records are created automatically in QuickBooks — no team member needs to re-enter data from auction records
Sales, operations, and finance work from shared transaction records with structured workflows.
Live sync monitoring shows posted, pending, and attention-required transactions.
Dashboards provide visibility into accounting activity, sync health, and financial status.
BUSINESS CHALLENGES
Challenge
Manual Accounting Work
Root Cause:
Staff were spending too much time re-entering the same data across disconnected systems after every auction cycle
Business Impact:
Operational overhead increased with sale volume; finance teams fell behind on reconciliation and close cycles
Challenge
Disconnected Team Handoffs
Root Cause:
Sales, operations, and finance had no shared system — updates were passed manually between departments after each auction
Business Impact:
Day-to-day tasks slowed down and critical updates were frequently lost or delayed at handoff points
Challenge
Complex Settlement Logic
Root Cause:
Commissions, fees, and consignor payouts had to be calculated accurately across every transaction with no automated support
Business Impact:
Revenue leakage and payout errors were hard to catch without a structured, system-driven settlement workflow
Challenge
Limited Manager Visibility
Root Cause:
Leaders had no fast, reliable way to see sync status, what had posted, and what still needed review in one place
Business Impact:
Management decisions were delayed because insight required chasing reports from multiple people and systems
Challenge
Future Growth Pressure
Root Cause:
The business needed an integration structure that could support more than one accounting provider as they grew
Business Impact:
Single-provider dependency created long-term lock-in risk and made future expansion costly and complex
SOLUTION APPROACH
Principle
Event-Driven Accounting Record Creation
What We Built
Built the QuickBooks workflow so that accounting records are created automatically from the correct business events — sale completion, settlement approval, payment receipt — rather than from manual data entry steps
Why It Matters
The process stays consistent and auditable; finance teams no longer need to trigger accounting entries manually or monitor whether they happened
Principle
Modular Integration Structure for Future Scalability
What We Built
Designed the QuickBooks integration as a modular layer within the broader accounting platform — QuickBooks is handled cleanly today while the architecture remains ready for additional providers like Xero in the future
Why It Matters
The business is not locked into one accounting provider; new integrations can be added by implementing the same interface, reusing all existing business logic
USE CASES DELIVERED
Consignor Settlements - Keeps settlement values, commission calculations, and payout records aligned between the auction platform and QuickBooks in real time
Bill Payments - Supports payout-related accounting entries in QuickBooks in a structured, consistent way — reducing manual bill creation for consignor payments
Customer Mapping - Matches auction buyers to the correct QuickBooks customer records — ensuring invoices and payments are attributed accurately across the accounting system
Vendor Mapping - Keeps consignors tied to the correct QuickBooks vendor records — so settlement payments, bills, and payout history are always accurately linked
Sync Monitoring - Lets finance teams track the success, failure, and pending status of every QuickBooks sync job — with clear visibility into what needs attention
Backorder Tracking & Order Checks - Scheduled jobs run regular checks on open orders, backorder status, and allocation decisions — giving operations teams early visibility into what needs attention before it becomes a problem
Shared ODS API & Database Gateway - Provides a single controlled interface for all processor applications to interact with the database — handling merge, select, and stored procedure calls in a consistent, auditable way
Error Handling, Retry & Logging - Every integration flow includes structured error handling, retry logic, and audit trail logging so failures are visible, recoverable, and never silently lost across any part of the platform

BUSINESS OUTCOMES
Less Duplicate Data Entry
Buyer invoices, consignor settlements, and payment records are created automatically in QuickBooks — no team member needs to re-enter data from auction records
Cleaner Handoffs Between Departments
Finance and operations work from the same QB sync records after each sale closes — replacing manual email updates and spreadsheet reconciliation
Better Control Through Sync Tracking
Live QB sync monitoring means finance teams always know what has posted, what failed, and what is pending — without chasing status manually
Earlier Error Detection
Sync failures and mapping issues surface immediately through structured monitoring — caught and resolved before they affect month-end close or consignor payouts
Stronger Management Visibility
Managers can review QB sync health, invoice status, and settlement progress from the dashboard — without waiting for manual reports from the finance team
