I need a small service that connects our third-party platform to QuickBooks Online through the official API. Its single purpose is to analyse each incoming invoice, detect rounding errors or other amount mismatches, and resolve them automatically. Here is the flow I have in mind: • When the external system pushes an invoice, the service checks every line and total. • If the variance is within a configurable tolerance, it quietly posts the adjusting entry or creates the needed credit memo and applies it to the invoice. • If the variance is larger, the service still posts the adjustment but also flags the invoice for review and sends a notification to the accounting channel. The adjustment logic, flagging method (custom field, class, or other), and notification channel are all open to your recommendation as long as they stay within QuickBooks API guidelines. Deliverables • Clean, well-documented source code (Node, Python, or .NET preferred) • Deployment instructions for an Azure Function, AWS Lambda, or a lightweight VPS • QuickBooks sandbox setup with test data showing successful rounding-error corrections and mismatch flags • Postman collection (or Swagger file) for any endpoints the service exposes Acceptance criteria 1. An invoice containing a rounding variance ≤ tolerance is adjusted and closed without human intervention. 2. An invoice containing a larger variance is adjusted, marked “Needs-Review,” and triggers an email/Slack alert. 3. Every action is logged with enough detail to audit the change in QuickBooks. Please only take this on if you have shipped similar QuickBooks API automations before; a short note or link to a past project will help me choose quickly.

Hello, I can build the QuickBooks Online connector you need and deliver a production-ready service that automatically corrects invoice variances and flags exceptions for review. What I will deliver • A clean, well-documented .NET Core Azure Function (Node or Python also possible) that receives invoices from your external system, analyzes line items and totals, and applies adjustments through the official QuickBooks Online API. • A fully configurable tolerance value. If the variance is small, the service posts the adjusting journal entry or credit memo and applies it to the invoice. • If the variance is larger, the service posts the adjustment, marks the invoice as Needs Review using a custom field or Class, and sends an email or Slack notification. • Comprehensive, structured logging with full audit references to QuickBooks transaction IDs. • A QuickBooks Sandbox environment with test data proving both auto-correction and mismatch-flagging scenarios. • Deployment instructions for Azure Functions, AWS Lambda, or a lightweight VPS. • A Postman collection for testing any exposed API endpoints. Why I am a strong fit I have delivered multiple QuickBooks API integrations that automated posting, reconciliation, and variance handling. I follow QuickBooks API best practices and can recommend the safest adjustment approach and the most reliable flagging method. If this matches your expectations, I can prepare a brief technical outline and a QuickBooks Sandbox demo. Regards, Malik

Hi there, I’m Ian Brown, and I specialize in building QuickBooks Online integrations. I can create a service that automatically detects and resolves rounding errors or invoice mismatches using the QuickBooks API. How It Works: Invoice Analysis: The service checks each incoming invoice for discrepancies. Automatic Adjustments: For small variances (within a set tolerance), it posts the adjustment or creates a credit memo automatically. Review Flagging: If the variance is larger, the service posts the adjustment but marks the invoice as "Needs-Review" and sends an email/Slack notification to your accounting team. Audit Logs: Every action will be logged for full auditability. Deliverables: Clean Source Code: Node, Python, or .NET (your choice). Deployment Guide: Instructions for Azure, AWS Lambda, or VPS. QuickBooks Sandbox Setup: Test data showing the service in action. Postman/Swagger: For any exposed endpoints. Acceptance Criteria: Small variance invoices auto-adjust. Larger variance invoices flagged for review and notified. Detailed logs for audit. I’ve worked on similar QuickBooks API automations before and can share examples if needed. Let me know if you'd like to get started! Best, Ian Brown
