Customer programs
Four service families
Use one service, or combine them into one program with one point of contact. RELY can build a subassembly, inspect it, kit it and ship it under a single program.
Mechanical and electromechanical builds, PVC subassemblies, control boxes and line-ready components, built to approved requirements.
Explore contract assembly → Part sorting, inspection & containmentThird-party sorting, inspection, testing and rework at your plant, a supplier’s plant or RELY, against criteria you approve.
Explore sorting & inspection → Kitting & contract packagingProduction, service and retrofit kits, contract packaging of finished goods, variety packs, retail packouts and Amazon FBA prep.
Explore kitting & packaging → Value-added manufacturingRelabeling, repackaging, product preparation and light secondary operations, run to approved instructions with agreed checks.

Where the work runs
RELY runs defined work inside a customer or supplier facility under our on-site labor model, in RELY’s Menomonee Falls facility, or both. RELY manages the contracted work: supervision, training, work instructions, quality checks and reporting. It is not a staffing model where your team supervises extra people.
On-site example: inside a Wisconsin injection molder, RELY ran two-shift food-storage kitting with a RELY lead on each shift. When a labeling requirement was added mid-run, a 1,120-kit labeled validation run passed audit before full-rate restart, and the delivery timeline held: 132,115 kits from January 13 to June 10, 2026.

How programs start
RELY follows a structured process designed to move programs from quote to stable execution with clarity, control and speed.
We define requirements, volume, timing, materials, quality needs, procurement considerations and operating constraints so the quote reflects execution reality.
We build the process, labor approach, quality controls, procurement strategy and the right mix of equipment, automation, fixtures and tooling.
We validate details, align documentation, secure materials, implement controls and ramp with discipline from the first build.
As demand grows or requirements change, we scale with the structure needed to keep supply, production and performance aligned.
Quality, communication, speed
01 · Quality
ISO 9001:2015 certified for contract manufacturing and assembly, with documented work instructions at the cell, defined inspection steps and layered process audits.
02 · Communication
Each program has an identified primary contact and KPIs agreed around the work, so nobody in your plant chases status.
03 · Speed
RELY responds to urgent sortation and containment inquiries within one business hour. Deployment and completion timing depend on the scope.

Inside RELY
Processes are easier to trust when you can see how the work actually runs. Step inside RELY’s Menomonee Falls operation and see the people, production cells, training, quality controls and manufacturing programs behind the website.
RELY builds manufacturing programs around documented work instructions, trained people, defined quality controls, clear ownership and communication. That operating discipline is what allows work to move from launch into repeatable production and scale.
RELY Contract Manufacturing operates from a 52,000-square-foot manufacturing facility in Menomonee Falls, Wisconsin. RELY supports contract assembly, part sorting and inspection, containment, kitting, contract packaging, value-added and production-transfer programs, including electrical assembly, using documented work instructions, trained operators and defined quality controls.
A 26-second continuous walkthrough of RELY’s production floor in Menomonee Falls, Wisconsin, with production-floor sound and no narration. It opens at a wire harness cell, where two operators build and stage cable assemblies at a stainless bench beside guarded equipment with light curtains and printed visual instructions posted at the station. The camera then moves across the main floor, past more production cells, color-coded totes and cartons staged on pallets, pallet racking and operators working at assembly and packing tables. It continues through an equipment area with benchtop presses and wire-processing equipment and ends at a table of completed wire harnesses beside RELY’s contract assembly display boards.

Featured case · No. 20
A fast-growing water heater manufacturer was pulling its most experienced assemblers off the main line to build PVC subassemblies. RELY took over subassembly production and component procurement, and shipped kits ready to crate with the customer’s QC checklist.
Source: RELY Case Study No. 20. Figures apply to this program only.
The same idea at different scales: 300,000 kits through one coordinated program and 30,000+ variety packs with zero customer-reported pack-mix errors.
How relationships grow
Most RELY relationships begin with one defined job: a transfer, a recovery, a kit family. The larger program is earned by running that job well. Scope, minimums and commitments are set for each program.
Assembly transfer · No. 13
Production ran at RELY in under four weeks from go-ahead. The same customer then moved six more product lines: 210,689 units across seven lines, April 2021 to August 2022. Read the case
Recovery to on-site kitting
A Wisconsin injection molder first sent 5,498 held assemblies to RELY for recovery. That job built the trust behind the managed kitting program RELY later ran inside its plant. See the plastics story
Appliance switch lines
RELY ran an appliance switch assembly line in the customer’s plant, then moved it to RELY. Two years later, two more switch lines moved in. Read the program
Floor space & production transfers
When a new line, press or product needs the room, established assembly, legacy production or service parts can move to RELY under a documented transfer plan. Tooling, BOMs, work instructions and required approvals move with it. Formal approval stays with you and your customer.
Depending on the program: pilot builds, staged product transfers, parallel production, advance inventory, first-article approval, run-at-rate validation and defined cutover gates.
No. 20: 2,000 sq ft of customer production space freed when subassembly moved to RELY. Read the case
Appliance switch line: after the line moved to RELY, the customer installed three new molding presses in the freed space. Read the program
