WSA handles complex multi-component kitting, dynamic bundling, retail packaging, and subscription box assembly. We're built for the jobs basic 3PLs won't take.
From simple retail bundles to complex serialized hardware kits — WSA has the setup, the people, and the process to do it right.
Complex bill-of-materials kitting combining multiple SKUs into a single finished unit — with per-kit serialization and dynamic labeling as needed.
Create product bundles on demand — varying configurations assembled to meet changing promotional or retail needs without pre-built inventory.
In-house retail-ready heat-seal clamshell packaging — no need for a separate vendor, no delays, no back-and-forth logistics.
Recurring subscription box fulfillment — inbound coordination, assembly on your schedule, and same-day DTC shipping on launch day.
Custom-sized shipper boxes assembled with insert cards, tissue paper, branded packaging components, and your exact unboxing spec.
Big-box compliance packaging, hang tags, sticker application, and retail barcode labeling — ready for Walmart, Target, or regional retail.
If your product requires assembly, configuration, or custom packaging before it ships, WSA handles it — at scale, without sending work elsewhere.
Tablets, routers, IoT devices, and accessories assembled into deployment-ready kits — provisioned, packaged, and shipped to enterprise operators.
Supplement kits, wellness bundles, and DTC subscription boxes assembled and shipped to your customers on your cadence.
Holiday gift sets, promotional bundles, and retail-exclusive packages assembled to your retailer's compliance and barcode requirements.
OEM-compliant hardware kits assembled with exact component configurations, labeling, and documentation for dealer or fleet deployment.
Multi-SKU smart home bundles assembled, labeled, and packaged for retail shelves or DTC direct-from-warehouse shipment.
Workout kits, apparel bundles, and lifestyle sets assembled and packed per DTC unboxing spec — inserts, tissue, branded components included.
From scoping your BOM to shipping finished kits — every step happens under one roof in Kearny Mesa, San Diego.
We review your bill of materials, kit configuration, and output spec. We flag any issues before production starts — not after.
All inbound components received and verified at WSA. Each SKU logged, inspected, and staged for the kitting run.
Components assembled per your exact BOM — serials tracked, labels applied, QA checks run on every finished kit.
Finished kits packaged in retail or DTC spec and shipped same or next business day — tracking synced to your system.
Most 3PLs handle simple kitting. WSA handles the projects that other providers turn down.
Multi-SKU, multi-step kits with serialization, provisioning, and dynamic labeling — all handled in-house, no subcontractors involved.
Heat-seal clamshell, custom shipper box assembly, retail compliance packaging — no third-party vendor delays, everything in our facility.
We scope kitting projects quickly and can start production within days. Rush kitting runs are available for time-sensitive launches.
Unique to WSA: hardware can be provisioned with firmware or software, then immediately kitted and shipped — all in one workflow.
Every kit tracked by serial — full chain of custody from component receipt through outbound shipment, visible in your client portal.
Talk to the team actually running your kitting jobs. No tickets, no bots — direct communication from scope through delivery.
