Cart Handoff and Lightspeed POS Plan

A practical way this redesigned storefront could work next to the existing Lightspeed site while keeping checkout, discounts, customer accounts, and inventory inside the system Hidden Reef already uses.

The current Hidden Reef website runs on Lightspeed eCom (Shop ID 648211), which is connected to the store's point-of-sale workflow. Product inventory, sale pricing, orders, checkout, customer accounts, and customer-specific discounts already belong in Lightspeed.

The safest approach is not to replace that system. The redesigned site can run beside the existing Lightspeed site as a better shopping front end, while Lightspeed remains the final source of truth.

Recommended direction: let customers browse and build a cart on the new site, then hand that cart to Lightspeed checkout. At checkout, Lightspeed handles login, final pricing, customer discounts, taxes, payment, and the order record.

Step 1: Keep The Existing Store Live Lowest Risk

How it works

The redesigned site runs on a separate domain or subdomain, such as new.thehiddenreef.com or shop.thehiddenreef.com. The current Lightspeed site stays online and continues to work normally.

If the new site has a problem, customers and staff still have the existing tested store available.

What stays safe

  • Existing checkout remains available
  • Staff keep using the Lightspeed admin they already know
  • No payment or order workflow changes are required at launch

Boundary

  • The new site should launch as an optional front end first
  • The old site should not be turned off until the new flow is proven

Step 2: Let The Demo Cart Behave Like A Real Cart

How it works

Customers browse the redesigned site and add products to the cart here. The cart can show product names, quantities, images, and an estimated subtotal.

The cart should also make the pricing boundary clear: log in at checkout to see account discounts, rewards, and final pricing.

Customer experience

  • Browsing feels modern and fast
  • Customers can build a cart before leaving the new site
  • The site can show public prices and sale badges

Boundary

  • Customer-specific discounts should not be guessed on the new site
  • Lightspeed checkout should calculate the final total after login

Step 3: Send The Cart To Lightspeed Checkout API Phase

How it works

Each product on the redesigned site needs to map to its real Lightspeed product or variant ID. When the customer clicks checkout, a small private backend sends those cart items to Lightspeed and then redirects the customer to the Lightspeed cart or checkout page.

API credentials stay on the private backend. They should never be placed in browser JavaScript.

What Lightspeed handles

  • Customer login
  • Special customer discounts
  • Final price, tax, and shipping rules
  • Payment and order creation

What must be confirmed

  • The exact Lightspeed API/cart capabilities available on their plan
  • How product variants are represented
  • Whether cart creation or checkout links are supported directly

Step 4: Sync Inventory And Sale Items

How it works

Lightspeed should remain the place where staff add products, receive stock, change inventory, and create or remove sale items. The redesigned site should copy that information from Lightspeed instead of becoming another admin system.

For inventory that changes constantly, the best setup is a combination of webhooks and scheduled checks. Webhooks catch updates quickly; scheduled checks are the backup in case any webhook is missed.

Can sync from Lightspeed

  • Product names, images, categories, and brands
  • Inventory availability
  • Sale products and sale pricing
  • Product additions and removals

Boundary

  • The new site should not require staff to update products twice
  • If the API is unavailable, checkout should still fall back to Lightspeed

Step 5: Keep Store Management In Lightspeed

Operational boundary

The new site should be built so regular store work still happens in Lightspeed. Product updates, inventory changes, sale pricing, customer records, and order management should remain in the system staff already uses.

Getting Lightspeed API Access

To move beyond simple product links, Hidden Reef would need API access from the Lightspeed admin area:

The exact integration depends on the Lightspeed plan and API features available to this store. The first technical check should confirm product, variant, inventory, cart, customer, and sale-data access.

Practical first milestone: keep the current demo cart, add checkout messaging about account discounts, map demo products to real Lightspeed product IDs, and test whether a cart can be created or prefilled in Lightspeed checkout.

Current demo behavior

Browse the demo storefront and try adding items to the cart. The next improvement would be handing that cart to Lightspeed checkout while keeping final discounts and payment inside Lightspeed.
