We are a bookkeeping and financial consulting firm working with small business owners and entrepreneurs. Our clients are great at running their businesses but are not financially savvy, and our mission is to change that. We are building a Financial Intelligence Portal that sits on top of QuickBooks and turns raw bookkeeping data into simple, meaningful insights that any business owner can understand and act on - without needing to know what a balance sheet or EBITDA means. We already have a working version of the portal live with the frontend, database, and core financial engine in place. We now need an experienced developer to complete it. Full technical details, codebase documentation, database schema, and a clear list of what needs to be built are attached. Please review before applying. One hard requirement - you must have hands-on experience with the QuickBooks Online API and Intuit Developer platform, along with tools like React + vite, Node.js, Python, etc. Please include relevant examples in your application. Proposals without this will not be considered.

Hi, this is a very interesting build, and the QuickBooks Online requirement stood out to me right away. Since your frontend, database, and core financial engine are already in place, I can focus on the remaining integration work, backend fixes, and the plain-English AI insight layer without wasting time rebuilding what already works. I have experience working with custom web apps using React, Node, and Python, and I understand how important it is here to make financial data understandable for non-accountant users. If you share the remaining task list through the platform, I can review it carefully and move quickly.

I have already built a QuickBooks integration for MyBizPro/MyWorkbelt. I worked with QuickBooks API v3, authentication and sandbox testing. I also synced QuickBooks customers into the application's database. That is why your QuickBooks requirement immediately caught my eye. I can work with the existing integration instead of learning it from scratch. For the AI layer, I would keep one rule: AI explains the numbers; it never creates the numbers. Your P&L, cash flow and balance sheet stay calculated from real data. Claude then turns those figures into plain-English answers and scenarios. That also makes questions like “Can I hire another employee?” answerable from the actual financial data rather than guesswork. I would first complete the QuickBooks sync and field mapping. Then fix the existing Supabase issues and client data access. After that, I would improve the financial explanations and AI journey. My bid: $250 USD.

Hi — Elias here from Miami. I understand you're looking to build a Financial Intelligence Portal with QuickBooks Online integration, backend bug fixes, and a conversational AI layer. The goal is to make financial data accessible to non-accountants, empowering small business owners. What usually matters most here is creating a seamless user experience while ensuring data integrity. A common issue in systems like this is managing complex integrations and ensuring the AI translates financial terms accurately. The tricky part is maintaining performance as user demand scales while keeping the system reliable for future features. I would approach this by structuring the backend to handle integrations efficiently, possibly using a microservices architecture. This ensures maintainability and future-proofing. I've worked on similar platforms where real-time data processing and user-friendly interfaces were critical, focusing on stability and user experience. A few questions to better understand the scope: Q1 – What specific user roles and permissions do you envision for this portal? Q2 – Are there particular QuickBooks Online features that should be prioritized? Q3 – How will you handle AI output reviews to ensure accuracy? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hello, I am a honest dedicated full time developer. I read your requirements carefully and understand the existing Financial Intelligence Portal and the priorities: QuickBooks Online/Intuit OAuth 2.0 integration, QBO data synchronization, Supabase/PostgreSQL fixes and RLS, and the Anthropic Claude conversational AI layer. I have 10+ years of experience in full-stack development with React, Vite, Node.js/Python, PostgreSQL/Supabase, OAuth 2.0 and AI/LLM integrations. I can work directly with your existing codebase, map QuickBooks data into your current schema, implement secure accountant/QBOA-based integration, and resolve the existing database and access-control issues. For the AI layer, I can structure the prompts and financial context so users receive clear, actionable explanations rather than raw accounting figures, including scenario-based questions such as hiring affordability and cost-impact analysis. I will work with Agile methodology, provide 2 YEARS OF FREE ONGOING SUPPORT, complete SOURCE CODE, and assist from ZERO TO PUBLISHING where applicable. I understand that hands-on QuickBooks Online API and Intuit Developer experience is essential and would be happy to provide relevant examples and discuss the existing codebase and technical documentation. I eagerly await your positive response. Thanks.

Your existing Financial Intelligence Portal is a strong foundation, and I can complete the QuickBooks-first workflow while keeping the experience understandable for non-accountants. I have worked with QuickBooks Online and the Intuit Developer platform, including OAuth 2.0 authorization, accountant-led multi-tenant connections, report/invoice synchronization, and mapping QBO responses into application databases. I’ll first review the current React + Vite frontend, Node/Python services, Supabase schema, and the documentation provided. I’ll implement secure OAuth state and token handling, connect P&L, Balance Sheet, Cash Flow, and Invoice endpoints, support the accountant QBOA model, and create reliable sync logic for reconciled books. I’ll also resolve the documented Supabase upsert mismatch, test Debt Schedule and Shareholding saves, and configure RLS so admin and client visibility is correctly isolated. For the intelligence layer, I’ll refine the existing Anthropic Claude integration with structured financial context, guardrails, trend comparisons, and prompts that answer questions such as hiring affordability or a 10% cost increase in a friendly, plain-English tone. I’ll then improve the onboarding, responsive layouts, story-driven journey, role access, and 12-hour insight notifications. The PDF’s page 2 priorities align well with this implementation sequence.

Hello!, I am a Florida-based senior software engineer(frontend, backend, ecommerce, etc) and I read your project description carefully. I understand you need a Financial Intelligence Portal that integrates with QuickBooks Online, fixes backend issues, and adds a conversational AI layer that turns financial data into plain English for non-accountant users. I have about 15 years of experience with PHP, Python, Node.js, React.js, API development, database systems, and financial dashboards. I’ve built production-grade SaaS tools, AI copilots, and data-heavy portals where accuracy, clarity, and reliability really matter. My approach would be: review the current codebase and QuickBooks flow, fix backend bugs and data consistency issues, then build the AI layer so it gives useful, easy-to-understand answers for small business owners. I’m careful with details, especially when financial data and user trust are involved. If needed, I can also help shape the UX so the portal feels simple for non-accountants while still being powerful underneath. Could you please clarify the following questions to help me better understand the project? 1. Is the QuickBooks Online connection already partially built, or should I handle the integration from scratch? 2. What are the main backend bugs you already know about, and do you have logs or examples I should review first?

Hello, We recently built a similar intelligence platform for US law firms, bringing leads, conversions, revenue, marketing spend and commissions together so owners & different teams could understand what was actually happening in the business. I have also implemented QuickBooks OAuth/API integrations and AI-based reporting. For yours, give me the calculations and questions you want your clients to understand, and I can map the QBO data and have Claude explain it in plain English. I would first confirm the QBO plans/accountant setup, then we are good to go. I will also include 30 days of free support after launch to fine-tune the sync and AI responses. If this sounds aligned, let us talk through the current portal and your calculations and we can take it from there. Thanks, Sagar.
