Clarity Connect integration
Heartland Shopify Integration
Keep your Heartland Retail stores and your Shopify site on one set of items, stock counts and customers, with online orders posted back to Heartland.
Which Heartland, and what moves
Heartland means two things to a Shopify merchant. Heartland Payment Systems is a card processor, part of Global Payments since 2016. Heartland Retail is its point-of-sale software for shops, and that's what this integration connects. Heartland told merchants that Shopify would stop supporting Heartland Retail's built-in Shopify connection as of July 1, 2023.
Clarity Connect fills that gap through Heartland Retail's API. Items and stock by location go from Heartland Retail to Shopify, customers sync both ways, and Shopify orders become Heartland Retail sales orders, so stores and site sell from the same inventory.

Heartland Retail to Shopify record mapping
A typical starting map. Discovery confirms the fields, locations and rules for your stores.
| Heartland Retail | Shopify | Direction |
|---|---|---|
| Item (by SKU) | Product variant | Heartland Retail to Shopify |
| Inventory value at a location | Inventory level at a location | Heartland Retail to Shopify |
| Customer and addresses | Customer | Both ways |
| Sales order with payment | Order | Shopify to Heartland Retail |
| Location | Location | Matched once in discovery |
How the sync works
Items and stock from the stores to the site
Heartland Retail's API exposes items, item grids and inventory values by location. Connect maps each item to a Shopify product variant by SKU and updates Shopify's inventory level for each location on the schedule you set, so the site stops selling what the stores have sold.
Shopify orders into Heartland Retail
The API can create a sales order, add item lines, shipping and a payment record. Connect posts each Shopify order that way, against the location that will fulfil it, so the stock comes off in Heartland Retail as well.
Payments stay where they were taken
Shopify checkout runs on Shopify Payments or another provider listed in your Shopify admin, and in-store sales run on your Heartland processing. The integration moves the payment amount and reference onto the Heartland Retail order, never card numbers.

Heartland under Global Payments
Global Payments has reshaped itself since 2025. It sold Heartland Payroll to Acrisure in September 2025, and in January 2026 bought Worldpay while selling its Issuer Solutions business to FIS. It's also bringing its point-of-sale businesses together under the Genius brand and launched Genius for Retail in June 2025. If your stores have moved from Heartland Retail to Genius, discovery starts by checking what that system exposes.
Heartland Retail's API uses OAuth and also covers sales tickets, purchase orders and inventory transfers, so in-store sales can feed the ERP through the same connection. For payments into the ERP, see Global Payments through Clarity Payment Hub.
How Clarity Connect runs it
Clarity Connect is Clarity's integration platform. It keeps a persistent, two-way connection between Heartland Retail and Shopify and runs each flow as a task: orders the moment they're placed, stock on a timed schedule. If either side is unreachable, the job is retried instead of dropped. Clarity has built more than 3,000 integrations on it; demos are on Clarity's YouTube playlist, and the integrations directory lists the rest.
Discovery
A Clarity business analyst documents the data fields and workflows each system can share and which ones you need.
Tasks and mapping
Each flow becomes a Connect task, such as orders to the ERP or stock to the store, set to run in real time or on a schedule.
Testing
Orders and updates are run end to end, including the return trip of statuses back to the customer-facing system.
Live, with a dashboard
Queues and scheduled tasks show in Connect's Hangfire dashboard. A job whose target is offline is retried 10 times, every 30 minutes, and can be re-queued once the cause is fixed.
Clarity Connect is sold as a SaaS subscription at $599 a month or as a one-time license at $15,000 with no ongoing fees, and larger projects are priced to scope. See pricing.
Questions
Does Heartland Retail still connect to Shopify by itself?
Heartland told merchants that Shopify would stop supporting Heartland Retail's built-in Shopify integration as of July 1, 2023, after which it would lose functions and disconnect. Clarity Connect links the two through Heartland Retail's API instead.
Can Heartland process payments at Shopify checkout?
Only if Heartland appears as a provider in your Shopify admin's payment settings; Shopify decides which partners can process its checkout. This integration doesn't change that. It moves items, stock, customers and orders.
Which system is the master for stock?
Usually Heartland Retail, because the stores count and receive stock there. Discovery confirms it and sets how often Shopify is updated.
What does Clarity Connect cost?
$599 a month as SaaS, or a $15,000 license bought once with no ongoing fees; bigger projects are priced to scope. See pricing.
