Salesforce–Custom ERP Integration Setup

@Solutionzhere

Hi, SolutionzHere has integrated Salesforce with custom ERPs (bi-directional, near real-time, fault-tolerant). Approach: REST + Platform Events (near real-time) + scheduled batches → mapping layer (custom objects) → OAuth 2.0 → retry queues + dead-letter handling → centralized logging. Timeline: 2–3 weeks Cost: ₹1.5–2.5L (realistic—bi-directional + reliability; current budget is low) Deliverables: Design doc, sandbox deployment, test suite, handover. Ensures <5 min sync, data integrity, and robust error handling. Question: Does your ERP already expose REST APIs with webhook support or only polling endpoints?

Hello, As a salesforce partner and authorised reseller in india, I have successfully delivered multiple projects similar to yours. I would be happy to help you design and implement a robust bi-directional integration between Salesforce and your proprietary ERP system. As a 10x Certified Salesforce Architect with 13+ years of experience, I’ve delivered 100+ projects involving complex integrations across industries like finance, manufacturing, healthcare, and SaaS. I have strong expertise in Salesforce APIs, Apex callouts, OAuth 2.0, and middleware solutions like MuleSoft and Boomi. For your requirement, I will: - 1. Design a scalable integration architecture with clear data mapping for Accounts, Contacts, Opportunities, Orders, and custom objects. 2. Implement near real-time bi-directional sync using APIs or middleware (based on best fit). 3. Ensure secure authentication via OAuth 2.0 and HTTPS endpoints. 4. Build robust error handling, retry logic, and centralized logging. 5. Deliver clean, well-documented code and a concise admin/developer guide. I have previously integrated Salesforce with custom-built back-office systems, ensuring reliable data sync, high performance, and smooth UAT-to-production transitions. I can provide a detailed technical design, complete implementation, and walkthrough to meet your acceptance criteria. Let’s connect to discuss timelines and the best approach for your setup. Best regards, Deepak Certified Salesforce Architect

I saw your project and am confident I can deliver on this. I'm currently working on a similar project and prioritizing "Integration with other systems," focusing on our home-grown ERP. The seamless flow of data between Salesforce and our ERP is crucial. Objects like Accounts, Contacts, and custom tables need to sync bidirectionally within minutes. Using standard Salesforce APIs or middleware like MuleSoft, I ensure robust error handling and authentication via OAuth 2.0. The integration will be rock-solid with clear logging and a comprehensive admin guide. I guarantee a smooth hand-off for efficient operations. I invite you to view my portfolio, which showcases the quality and results of my past work. I look forward to hearing from you. Regards, Sadiya

Your Salesforce and homegrown ERP live in separate worlds—manual re-keying is eating your team's valuable time and introducing costly errors. I'll build a clean OAuth 2.0 REST API integration with scheduled batch syncing so Accounts, Contacts, Opportunities, Orders, and all custom objects stay in sync bidirectionally, every few minutes. Zero middleware complexity needed. ₹2500 | 5 days. Best regards, Val

I can design and implement a secure, bi-directional integration between your Salesforce org and proprietary ERP with a focus on reliability, scalability, and clean data flow. My approach will start with a detailed technical design covering object mapping (Accounts, Contacts, Opportunities, Orders, and custom objects), field-level transformations, and sync logic. For implementation, I can use Salesforce REST APIs with Apex callouts or a lightweight middleware layer (Node.js/Python) to handle orchestration, depending on what best fits your ERP architecture. The integration will support near real-time sync using event-driven triggers (webhooks/platform events) combined with scheduled jobs for bulk operations. I will implement robust error handling, retry mechanisms, and structured logging on both Salesforce and ERP sides to ensure visibility and stability. Authentication will be handled securely via OAuth 2.0, and all endpoints will follow best practices for encrypted communication. I have experience working with API integrations and custom backend systems, which allows me to adapt quickly to bespoke ERP structures and ensure accurate data synchronization. You will receive a complete solution including design documentation, tested integration setup in sandbox/staging, and a clear handover guide with walkthrough support.

Hi, Home-grown ERPs are actually my favourite to work with no cookie-cutter connector, so everything is built to fit exactly what you need. I've connected Salesforce to custom back-office systems before using Change Data Capture, Apex callouts, and REST APIs the same stack you're describing. Bi-directional sync, OAuth 2.0, solid retry logic with proper logging I've been down this road and know where the potholes are. I'll deliver everything on your list: design doc, working code on your Sandbox, a proper test suite, and a handover session where you actually understand what's running. Quick question before I sketch a timeline what does your ERP expose today? REST endpoints, a message queue, something else? That shapes everything. Happy to jump on a call if that's easier.

Hi there, You’re absolutely in the RIGHT PLACE. I’ve delivered SIMILAR PROJECTS multiple times and know EXACTLY how to execute this efficiently and correctly from day one. To lock down the SCOPE, TIMELINE, AND PRICING, I’ll need to ask you a few key questions. Unfortunately, Freelancer’s 1500 CHARACTER LIMIT doesn’t allow me to break everything down properly here. Let’s jump on CHAT so I can show you my PROVEN PAST WORK, walk you through the REAL RESULTS I’ve delivered, and outline a CLEAR ACTION PLAN for your project. You’ll immediately see why my approach is DIFFERENT and EFFECTIVE. If you’re serious about getting this done RIGHT, I’m ready to move forward. Looking forward to CONNECTING and WINNING TOGETHER. Cheers, Mayank Sahu

Hi, This is exactly the kind of integration I’ve delivered before—connecting Salesforce with custom-built ERP systems using a clean, reliable, and scalable architecture. I understand your priority is **true bi-directional sync** with strong reliability, not just basic API wiring. Here’s how I’d approach it: **Architecture & Approach** * Use Salesforce REST APIs + Apex callouts with OAuth 2.0 authentication * Introduce a lightweight middleware layer (Node/Python) or use MuleSoft if complexity grows * Event-driven + scheduled sync (near real-time + nightly bulk jobs) * Queue-based retry mechanism for resilience and <5 min sync targets **Core Capabilities** * Bi-directional sync for Accounts, Contacts, Opportunities, Orders, and custom objects * Field mapping with strict validation (no truncation/loss) * Conflict resolution strategy (last-write or rule-based) * Bulk handling (10k+ records) with batching and throttling * Centralized logging + error tracking on both Salesforce and ERP sides **Deliverables Covered** ✔ Technical design doc (data mapping, flow, architecture) ✔ Fully deployed integration (Sandbox + ERP staging) ✔ Test plan with edge cases (create/update/delete/bulk/errors) ✔ Admin + developer handover docs + walkthrough The budget can be finalized and may fluctuate after a detailed discussion—especially once I review your ERP API structure and data models. Let’s build this the right way ?

Proposal: Bi-Directional Salesforce & Proprietary ERP Integration Attention: Project Lead, Integrating a "home-grown" ERP requires more than a standard connector; it requires a custom architectural bridge that respects the unique logic of your back-office system. As a Salesforce Technical Architect leading a team of 10 senior developers, I provide the high-level design and the collective horsepower to deliver a robust, secure, and fully documented sync. Technical Strategy • Architecture: We will utilize Apex Callouts and REST API Resources for a lightweight, middleware-free integration. Queueable Apex will handle bi-directional updates to ensure a <5-minute sync without impacting UI performance. • Data Integrity: Using External IDs and an Idempotency Layer, we will prevent data loops and duplication across Accounts, Contacts, and Orders. • Bulk & Security: We will leverage Bulk API 2.0 for nightly 10k-row jobs and OAuth 2.0 (JWT Bearer Flow) for secure, encrypted communication. • Resilience: A custom Integration Log will capture errors with automated retry logic, surfaced via a Salesforce Dashboard. Deliverables 1. TDD: Full data mapping and flow diagrams. 2. Code: Production-ready Apex/Integration logic. 3. QA: Full test evidence for bulk, error, and CRUD scenarios. 4. Hand-off: Commented source code and a concise Admin Guide. We are ready to start immediately to meet your production goals. Best Regards, Surender Goswami Salesforce Technical Architect
