Necesito añadir dos funcionalidades críticas a mi tienda Shopify: 1. Límite de carrito Cada pedido debe restringirse a un máximo de 60 ítems. El sistema debe impedir que se agreguen productos adicionales cuando se alcance ese tope y mostrar un mensaje claro al usuario. 2. Sistema de crédito para clientes B2B Ciertos compradores podrán finalizar su pedido sin pago inmediato. Quiero gestionarlo “a través de un grupo específico de clientes”; solo quienes pertenezcan a ese grupo verán la opción de finalizar compra a crédito. El pedido debe registrarse normalmente en el admin, marcando de forma visible que está “pendiente de pago”. Nuestra tienda cuenta con conexion a un software ERP, donde todo esto debe no alterar el normal proceso de las operaciones (Nombre del ERP: Defontana) Alcance técnico solicitado • Configuración o desarrollo del código necesario (Liquid, Shopify Scripts, Functions o apps privadas) sin afectar el rendimiento existente. • Interfaz simple en el panel de administración para: – Asignar o quitar clientes del grupo de crédito. – Ajustar el número máximo de artículos si en el futuro cambia. • Garantizar compatibilidad con el checkout estándar de Shopify y con apps de descuentos ya instaladas. • Documentación breve para instalación y mantenimiento. Qué incluir en tu propuesta • Propuesta detallada de proyecto: enfoque, herramientas y fases. • Evidencia de experiencia previa en Shopify; valoraré especialmente casos B2B. • Plazo estimado (lo necesito lo más pronto posible) y puntos de control intermedios. Entregaré acceso a mi tienda y cualquier clave API necesaria una vez aceptada la propuesta. Espero una solución estable, bien documentada y lista para producción.

Hi, Soy desarrollador especializado en Shopify con experiencia en B2B y lógica avanzada de carrito. Propongo implementar el límite de 60 ítems mediante Shopify Functions o script/cart-level personalizado, con mensaje claro y parámetro editable desde el admin. Para el crédito B2B, crearé un grupo de clientes con tag y opción especial de checkout a crédito visible solo para ellos, marcando pedidos como pendientes de pago sin alterar la integración con Defontana, manteniendo compatibilidad con descuentos y documentando todo. Let's discuss in chat as I have some queries to ask regarding the project to proceed further.

Hi, I will implement both the 60-item cart limit and the B2B credit checkout for your Shopify store. For the cart limit, I will use Cart Transform or Shopify Functions to enforce the cap without slowing the storefront. For the credit system, I will tag customers within a specific group so they see a "buy on credit" option, with orders flagged as pending in admin — all compatible with Defontana's sync. Questions: 1) Are you on Shopify Plus, or standard Shopify? 2) How does Defontana currently sync orders — via API or app? Looking forward to your response. Best regards, Kamran

Hi, Good Day Your requirements are clear—these aren’t just small tweaks, but critical features that must work reliably without breaking your current Shopify + ERP (Defontana) flow. For the cart limit, I’ll implement validation at both frontend and backend levels (using Shopify Functions/Scripts) to strictly enforce the 60-item cap and display a clear message when the limit is reached. For the B2B credit system, I’ll create a customer-tag-based logic where only approved clients see a “Pay Later” option at checkout. Orders will be placed normally but marked clearly as pending payment, ensuring full compatibility with your ERP integration and existing workflows. I’ll also include a simple admin-friendly setup so you can manage credit customers and adjust limits without touching code. Everything will be tested carefully to ensure it works smoothly with your current checkout and discount apps. This is a simplified overview of the approach. I can share similar Shopify/B2B work and deliver this quickly with proper documentation. Quick question—are you currently using Shopify Plus, or standard Shopify checkout? Regards, M Adeel

Hello, I understand how crucial it is to implement these features smoothly in your Shopify store. For the cart limit, I can develop a reliable solution that restricts each order to a maximum of 60 items, providing clear, user-friendly alerts when the limit is reached. The maximum can also be easily adjusted from the admin panel if needed. For the B2B credit system, I will set up a dedicated customer group that allows selected buyers to complete purchases on credit. Orders will appear as “pending payment” in Shopify, fully compatible with your existing ERP (Defontana) and checkout process. I’ll also provide a simple admin interface to manage the credit group and ensure all features integrate seamlessly with your current apps. Clear documentation and testing will be included to guarantee a stable, production-ready solution. Best regards, Azad

Puedo implementar un límite de carrito sólido y un sistema de crédito B2B en Shopify sin romper tu checkout ni la integración con Defontana. Entiendo que necesitas bloquear el carrito en 60 ítems con mensaje claro, y habilitar “compra a crédito” solo para un grupo específico, registrando pedidos como pendientes de pago. Lo resolveré usando Shopify Functions + validación en carrito y checkout, y un flujo B2B basado en etiquetas de cliente o segmento, manteniendo compatibilidad con descuentos y tu ERP. He implementado un sistema similar donde clientes B2B podían finalizar pedidos sin pago inmediato mientras el resto seguía flujo normal, sin afectar integraciones externas. Puedo entregarlo rápido con panel simple para gestionar clientes de crédito y ajustar el límite. ¿Actualmente usas Shopify Plus o estándar, y cómo está conectado Defontana al flujo de pedidos?

I can help with this, I will implement both features on your Shopify store a 60-item cart limit that blocks additional products and displays a clear message to the user, and a B2B credit system where tagged customer groups can complete checkout without immediate payment, with orders marked visibly as "pending payment" in admin. Both will be built to work with your existing checkout flow, discount apps, and Defontana ERP integration without disrupting current operations. For the credit checkout, I will use Shopify Functions with a customer metafield tag rather than relying on draft orders this keeps the order flow standard so your Defontana sync continues processing orders normally, just with a payment status flag your ERP can read. Questions: 1) How does your Defontana integration currently sync orders through an app, API, or webhook? 2) Should the cart limit apply to total items or total unique products (e.g., 10 units of one SKU — does that count as 10 or 1)? Ready to start whenever you are.

Your 60-item cart limit and B2B credit system needs custom Shopify Functions for the cart restriction plus customer group logic for the credit checkout option. I'd handle this through Shopify's checkout extensibility API to ensure it plays nice with your existing discount apps and Defontana ERP integration. I built a similar e-commerce customization recently - a WooCommerce store with custom cart functionality and customer group management. Also developed a full invoicing platform with customer segmentation that might apply here. You can check out more at ffulb.com. Need Shopify store admin access and API credentials to assess your current setup and confirm the best approach for both features. Once I take a look at your theme and existing apps, I can get this rolling quickly. Ready to start whenever works for you.
