Interesting project, I will deliver the full B2B ordering system: native iOS 14+ and Android 10+ apps with offline order-taking and auto sync, a web app, an admin panel, and the RESTful backend connecting everything to your ERP. On a similar B2B build, structuring the offline queue with conflict resolution at the field level (not the record level) eliminated duplicate orders during sync. I will apply the same approach here. Questions: 1) Which ERP system will we integrate with, and does it already expose a RESTful API or will we need a middleware layer? 2) For the SMS invitation flow, do you have a preferred provider (Twilio, MessageBird), or should I include that recommendation? Share your current ERP documentation or API specs and I will map out the bidirectional sync endpoints this week. Looking forward to your response. Best regards, Kamran

Hi, I'm Rafael. I understand you need native B2B apps with offline order-taking that syncs automatically, an SMS-based invitation/login using unique codes, and bidirectional ERP sync including nightly product/inventory updates plus product photo sync via FTP. I focus on building the ordering flows, approval workflows and customer-specific price lists so they behave predictably for sales reps and approvers. A practical approach is a local queued order store on the device with idempotent sync and simple conflict rules so offline orders never duplicate. Do you already have ERP API documentation and FTP credentials, or must I map fields from scratch? Contact me through Freelancer chat to discuss this project in detail and estimate realistic timing and cost.

Your brief is well thought out, especially the offline ordering, customer-specific pricing, and ERP synchronization requirements. We have experience with custom business systems and can build this with a clean backend, reliable API structure, and an easy-to-manage admin area. The requester/approver workflow and commercial policy logic are the kind of details that need proper planning from day one. I’d be happy to map the full flow in a clear development sequence.

Hey there, Building a B2B ordering system where sales reps can keep taking orders offline while staying fully synced with your ERP is what will make this reliable in day to day operations. I will develop the native iOS and Android apps, web app, admin panel and RESTful API around your offline mode, SMS based login, approval workflows and customer-specific price lists. The sync process should also handle conflicting updates cleanly after reconnecting to avoid duplicate or missing orders. I recently worked on a business ordering platform with ERP synchronization, role-based approvals and scheduled data imports, so I know the sync layer is where most long-term issues appear. I will validate the API, nightly imports, FTP photo sync, and order flow before deployment to keep everything dependable from launch. Which ERP will the RESTful API be integrating with? Looking forward to collaborating with you. Portfolio: https://www.freelancer.com/u/Hammadhassan21 Best regards, Hammad Hassan...
