Hi there, I have worked on 6amMart-based systems (Laravel + Flutter) and understand how its services, provider architecture, and API structure are organized, especially when it comes to modifying core logic without breaking existing flows. I can help reshape your platform into LEOZIN with proper B2B + B2C separation, including GST-based signup validation, circle-zone delivery logic, runsheet-based rider authentication, and split admin dashboards for wholesale and retail. My approach will be to first work on the Laravel backend services, implementing GST validation, invoice logic (HSN/SAC, tax slabs), payment gateway integration (Razorpay + Cashfree), and inventory rules like pack-size mapping and FIFO. Then I’ll align the Flutter apps with updated APIs, ensuring B2B/B2C flows, delivery logic, and checkout work seamlessly without affecting existing functionality. I will keep all changes modular and clean within the current architecture, update API documentation, and ensure builds run smoothly across Android, iOS, and Web with proper testing on critical flows. I would request to connect and review your current codebase and priorities so I can start directly with the first set of pillars. Thanks, Rahul A.

Hi, We’ve developed multiple on-demand solutions with complex workflows, including a grocery delivery app that connects customers with local stores and delivery drivers. We understand the importance of a seamless experience for all three user types—customers, store owners, and delivery drivers. We can also enhance your existing Laravel backend with new features like web push notifications, which can significantly improve user engagement and retention. Let’s schedule a quick 10-minute call to discuss your project in more detail and ensure I fully understand your requirements. I usually respond within 10 minutes. I’m eager to learn more about your exciting project. Best regards, Adil

Your Circle-Zone delivery engine will fail under concurrent B2B bulk orders if you're still using 6amMart's default single-zone logic. The stock deduction race condition between wholesale pack-size orders and retail unit orders will cause overselling within 48 hours of launch. Before I architect the dual-dashboard split, I need clarity on two things: Does your B2B flow require real-time inventory sync across multiple warehouses, or is this single-location FIFO? And are your GST invoices hitting GSTIN validation APIs, or just formatting static PDFs with HSN codes? Here's the execution path: - LARAVEL SERVICE LAYER: Refactor order processing into separate B2B and B2C pipelines with isolated middleware chains, preventing wholesale minimum-order logic from bleeding into retail checkout. - CIRCLE-ZONE ENGINE: Build a PostGIS-based zone matcher that calculates delivery slots and charges in under 100ms, caching restaurant visibility per zone to avoid N+1 queries on the Flutter app. - RAZORPAY + CASHFREE: Implement a payment gateway abstraction layer with webhook idempotency and automatic retry logic, ensuring refunds route to the correct processor even if the admin switches gateways mid-transaction. - GST INVOICE GENERATION: Create a template engine that pulls live tax slab data, applies rounding per CGST/SGST rules, and stores audit trails for every invoice revision. - RUNSHEET AUTH: Replace rider login with daily JWT tokens tied to runsheet IDs, expiring at midnight to prevent credential reuse across delivery cycles. I've customized three 6amMart instances for clients scaling from 500 to 12K daily orders. I don't take projects where the existing codebase has undocumented hacks. Let's do a 20-minute technical walkthrough of your current Laravel services before I commit to the 7-day timeline.

I’ve worked on Laravel + Flutter projects where core logic had to be reshaped to serve distinct user types without breaking existing flows. For your B2B GST lock, I’ll enforce the validation strictly during sign-up and adjust the user roles for the separate dashboards you need. For the Circle-Zone delivery engine, I’ll design a geo-fencing logic to control slot availability and restaurant visibility based on customer location, similar to a past delivery app I enhanced. The runsheet-based rider login sounds unique—confirming, should the sheet code expire daily or remain valid as long as the rider is active that day? Integrating Razorpay and Cashfree side-by-side is straightforward; I’ll ensure smooth selection at checkout and seamless refund handling without interfering with existing payment flows. The advanced inventory setup with pack sizes and FIFO will fit cleanly within your current services layer. I’ll update API docs, write tests for these critical features, and keep builds clean across Android, iOS, and Web. If you can share an APK or link of your current instance, I can quickly validate my approach and start immediately to meet your 7-day target.

@waqaswebmaster

Hi There This is not a surface-level 6amMart edit, it’s a core architecture split where B2B and B2C rules must coexist without corrupting existing flows. I’d handle it by isolating wholesale vs retail logic at service, role, checkout, inventory, and invoicing layers so GST locks, circle-zone delivery, rider sheet auth, and dual payment rails stay clean and testable. I’m comfortable working directly inside Laravel and Flutter core structures where bad shortcuts usually create long-term regressions. Before moving fast on the 7-day window, which pillar is currently the most fragile in your existing codebase — delivery logic, auth flow, checkout, or inventory behavior? best regards Waqas A.

@aadips

Reshaping 6amMart into LEOZIN with both B2B wholesale and B2C retail logic cleanly separated on a single Laravel codebase is exactly the kind of deep-core customization we specialize in. Our approach starts by forking the service layer into wholesale and retail contexts before touching any UI — this ensures zero regression on existing buyer and seller flows. The Circle-Zone delivery engine, dual Razorpay and Cashfree checkout with admin refund controls, and GST-ready invoices with HSN/SAC slab handling will each be built as isolated Laravel services with proper unit and feature tests. The runsheet-based rider credential flow and dual admin dashboards (Wholesale vs. Retail with independent roles and menus) will follow the existing Flutter provider architecture to keep Android, iOS, and Web builds compiling cleanly from day one. We have delivered 40+ Laravel backends with multi-gateway payment integrations, multi-role admin panels, and inventory systems with FIFO stock logic — the full 20-pillar scope here is well within our standard delivery. Our team of 15+ developers holds a 4.9-star rating across 118 reviews with 97% on-budget delivery. Do you have the existing 6amMart codebase available in a private repo, and have all 20 pillars of the specification been finalized?

Small, deep edits to core ordering logic on a live Laravel + Flutter stack are the riskiest work there is. I’ve done exactly that under tight deadlines and kept buyer/seller flows intact. The best thing about me is I’ve worked on a very similar project recently: I converted a marketplace into a hybrid B2B/B2C platform, added mandatory GST capture for business signups, implemented zone-driven delivery slots, dual payment gateways, and GST-compliant invoicing with HSN mapping. I matched changes into existing Laravel services and the Flutter provider layer so builds stayed clean. I understand the expected user flows: separate Wholesale and Retail dashboards and role menus, B2B signup blocking without GSTIN, Circle-Zone controlling slot visibility and charges, runsheet code auth for riders, Razorpay and Cashfree selectable at checkout and refunds, and FIFO inventory with pack-size and min-order rules. I’ll keep logic inside current services, update API docs, add tests and ensure first-run builds. I can save you time because the tricky integrations and invoice rounding rules are already done on my last project. Quick questions: should Circle-Zone be radius-based or support polygons, and can a restaurant belong to multiple zones? For GST invoices, do you have HSN/SAC per SKU ready or should the system prompt admins for missing mappings? If that sounds right, let’s chat or hop on a quick call. Regards Ali Zain!!
