Shopify Development

Technical Q&A

Topic summary

A developer is planning to migrate multiple e-commerce sites to Shopify and needs guidance on implementing specific features that integrate with external stock control systems and modify cart behavior.

Key Requirements Being Evaluated:

  • Stock synchronization across web and physical stores (including reserved inventory)
  • Custom promotions and price bands for different customer segments (loyalty/trade members)
  • Delivery timeslot selection during checkout
  • Pre-ordering capabilities
  • DigiTickets integration
  • Customer loyalty points and discount coupon management
  • Gift card payment integration
  • Remote API-based cart discount updates

Current Status:
The inquiry seeks clarification on which features are natively supported versus requiring apps/custom development, and whether specific Shopify plan tiers are needed. One respondent confirmed these features are achievable through combinations of apps and custom API work, with implementation details varying by plan level. The discussion remains open for further technical guidance.

Hi all,

I’m wondering if anyone can help point me in the right direction.

We are looking at migrating a large number of existing client’s e-commerce sites over to Shopify, many of which would require a call back to our stock control system or need to affect the basket contents within Shopify.

Does anybody know whether any of the below are possible, and if so whether they require a particular Shopify plan level in order to implement them…

  • Promotions
  • Stock position (web and multiple stores) - consider reserved
  • Pre-ordering
  • Delivery scheduling and diary (Pick from a list of delivery timeslots within checkout)
  • Price bands (e.g. Discounts for loyalty members / trade members etc)
  • DigiTickets - is there an integration already for this?
  • Customer area for adding points, accessing discounts coupons
  • Use of Gift Card system with Shopify (i.e. Payment methods)
  • Update cart with discounts from remote API

Thanks in advance!

Hi Andrew,

What you’re looking to achieve is definitely possible on Shopify including things like dynamic promotions, delivery time selection, loyalty pricing, and even syncing with external stock systems.

Some of these will depend on the Shopify plan and might need a mix of apps or custom API work. There are also a few lesser-known solutions for features like pre-orders and remote cart updates that aren’t widely talked about.

Happy to point you in the right direction if you’re still exploring options.

Hey,

For Shopify-only implementation: Promotions and Price bands work through Discounts in admin. Stock position across locations requires Shopify Grow plan or higher (Products → Inventory). Pre-ordering needs enabling Continue selling when out of stock per product. Delivery scheduling, Customer area points, Cart updates via remote API, and DigiTickets integration aren’t available natively.

For pre-ordering specifically, K1 PreOrder automates this (I’m the founder) with automatic button replacement, threshold-based scheduling, and inventory management. K1 PreOrder listing if relevant.

Happy to help with Shopify setup or custom development approach.

Best regards,
