Engineering Subscriptions as Infrastructure, HALO is Now a Recharge Partner.

HALO is now a Recharge Agency Partner, available in the Recharge partner directory. Subscription programs on Shopify rarely stall on the subscription platform itself; they stall where recurring billing collides with the pricing logic, ERP reconciliation, and migration sequencing the storefront already owns.
What we build on Recharge
Recharge is a subscription management platform that stores subscription contracts, holds payment methods on file, schedules recurring charges, and generates the recurring orders that follow. Recharge's Agency Partner Program exists to connect merchants with qualified partners that implement and optimize those programs.
Many subscription launches are straightforward, and Recharge is built to keep them that way. What a partner like HALO adds there is speed, a properly tested launch, and not having to hold the details yourself while running everything else.
The work gets harder when the program has to coexist with systems the storefront already owns:
Subscriptions wired to ERP for revenue reconciliation and to CRM for lifecycle marketing
Eligibility and pricing rules enforced through the Recharge API rather than theme-level display logic
Shipping and discount behavior reconciled against rules the storefront already enforces
Cart-value tools already in the stack — Rebuy or equivalent, handling cross-sell, upsell, and bundling — reconciled alongside Recharge
Subscriber migrations between stores and between platforms
Where these programs actually break (Two patterns from a recent engagement)
A subscribe-and-save widget offered logged-in customers a subscription that cost more than the one-time price they were already paying. Subscription discounts compute against the base price in Shopify Admin, not the price a store's Shopify Functions logic resolves per customer. Shopify's documentation for the Cart Transform Function API lists subscription recurring orders as unsupported and rejects cart transform operations when a selling plan is present on the line. Two systems both claiming final authority on price, and the platform only lets one win.
Subscriber migrations have a fixed dependency order: customers and products, then payment methods, then subscription contracts, each depending on IDs from the prior step already existing in the destination. The less obvious rule is that the customer-facing blackout is governed by cutover, not by how long the migration takes. A subscriber can't be updating a credit card in one store while their billing lives in another.
Sitting between the platforms
Neither problem is solved inside a single vendor's documentation. Both were resolved by us working across Shopify's teams, Recharge's teams, and the merchant's own engineering and finance stakeholders.
That translation work is most of the job on complex subscription builds. Recharge documents the Shopify Checkout Integration thoroughly, and Shopify has well-documented its Functions APIs. The gap between the two is typically where implementations live or die, and nobody owns that gap by default.
Where HALO fits
We are a Shopify Select Service Partner, ISO 27001 certified, and an NMSDC-certified minority-owned business. Our merchant and e-commerce practice designs, builds, and operates commerce systems where subscriptions sit inside custom pricing logic, ERP and CRM integration, and multi-storefront consolidations. On a recent consolidation, we migrated 30,000+ active subscription accounts into a single governed instance with plans, payment methods, and billing dates intact.
Subscriptions may look like a merchandising 'feature' but, in reality, behave more like a second commerce system, requiring management.
