CUSTOM
COMMERCE
SYSTEMS.
We build custom commerce backends and operations software for orders, inventory, product data, fulfillment, and integrations when platform capabilities alone do not fit the workflow.

COMMERCE OPERATIONS.
Order & Inventory Systems
We build order workflows and inventory synchronization across storefronts, marketplaces, warehouses, and fulfillment systems, including allocation, reservation, and routing rules.
- Order workflow automation
- Inventory synchronization
- Allocation & fulfillment rules
- Warehouse integrations
Product Information Management (PIM)
We centralize product and variant information, SKUs, pricing structures, media assets, localization workflows, and distribution to commerce channels.
- Product & variant data
- Pricing structures
- Localization workflows
- Channel syndication
Commerce Operations Tools
We create admin dashboards, support tools, fulfillment workflows, bulk operations, reporting, and audit history around day-to-day commerce operations.
- Operations dashboards
- Bulk workflows
- Role-based access
- Audit history
Integrations & Middleware
We connect Shopify and other storefronts with ERP, WMS, CRM, marketplace, and legacy systems, using queues and background processing when the workflow requires them.
- ERP / WMS / CRM integrations
- APIs & webhooks
- Message queues
- Retry & failure handling
ENGINEERING STACK.
We choose databases, application frameworks, queues, and infrastructure based on consistency requirements, transaction volume, integrations, and operational constraints.
// Reserve available stock with one conditional UPDATE
func (s *InventoryService) Reserve(
ctx context.Context,
sku string, qty int,
) error {
const q = `
UPDATE inventory
SET available = available - $1,
reserved = reserved + $1
WHERE sku = $2
AND available >= $1
`
res, err := s.db.ExecContext(ctx, q, qty, sku)
if err != nil {
return err
}
if n, _ := res.RowsAffected(); n == 0 {
return ErrInsufficientStock
}
return nil
}
FREQUENTLY ASKED QUESTIONS.
When does a custom commerce system make sense alongside Shopify apps?
Standard Shopify apps are often the right choice. A custom commerce system makes sense when a business has workflows, integrations, data models, or operational requirements that off-the-shelf apps do not cover well. Custom integrations still need to respect Shopify's platform behavior and API limits.
How do you choose the architecture for a commerce system?
We choose architecture based on workflow complexity, integration requirements, transaction volume, consistency needs, and the client's existing infrastructure. Technologies may include Ruby on Rails, Go, PostgreSQL, Redis, message queues, and cloud services where appropriate.
Can you integrate legacy ERP or WMS platforms?
We can integrate storefronts and commerce workflows with ERP, WMS, and other legacy systems. Depending on the systems involved, an integration may use APIs, webhooks, scheduled jobs, queues, file exchange, or SOAP/XML interfaces, with monitoring and failure handling designed around the workflow.
How do your systems handle bursts in order or inventory events?
For workloads with bursts of events, queues and background processing can decouple incoming events from downstream systems. Idempotency controls, retries, queueing, and monitoring help manage duplicate events and temporary failures, with the design matched to the consistency and recovery requirements.
