Frequently Asked Questions
Our supply chain is fragmented, different vendors for cells, BMS, plastics, PCBs. Can you simplify this for us?
Simplifying complex, fragmented supply chains is one of the core reasons customers work with Karkhana.io. Instead of managing separate vendors for cells, BMS, plastics, PCBs, and assembly, we bring everything under one roof. We take ownership of sourcing, based on your BOM and specifications, and handle vendor coordination, quality checks, assembly, testing, and logistics. This reduces your operational load, shortens lead times, and improves traceability. You get a fully integrated, production-ready product without the hassle of chasing multiple suppliers.
Can you help us manufacture products that need BIS certification?
With the launch of our BIS-compliant captive factory in Bengaluru, Karkhana.io now offers end-to-end manufacturing support for smart consumer products that must meet regulatory BIS standards. This facility is purpose-built to align with BIS certification requirements ensuring the right infrastructure, documentation, and process controls are in place from day one.
Whether you’re looking to launch a new product or scale an existing one, we help you navigate the certification process while delivering speed, consistency, and regulatory readiness at scale.
We’re launching a product in multiple SKUs. Can you handle configuration-level assembly?
Launching products with multiple SKUs is something we handle routinely at Karkhana.io. Our operations are designed for configuration-level assembly, allowing us to manage variations in hardware, firmware, enclosures, or packaging with precision. We maintain strict process documentation, SKU-wise kitting, and quality control to ensure each unit is built exactly as specified.
Do you offer components/batch-level material traceability for audits or certifications?
We provide component- and batch-level material traceability as part of our standard process. Every part used in production is logged with supplier details, lot numbers, and assembly data, enabling full traceability for audits, certifications, and field failure analysis. This is especially critical for sectors like automotive, medical, and energy, where compliance and accountability are non-negotiable. You get clear, organized traceability records, not just for quality control, but to meet any regulatory or customer requirement with confidence.
Do you build custom test jigs for complex functional testing?
We support both build-to-order (BTO) and forecast-based production models. For customers with dynamic demand or multiple configurations, BTO allows us to assemble units against confirmed orders while managing inventory efficiently. For high-volume or stable SKUs, we work with forecast-based schedules to plan procurement, buffer stock, and production runs. Our systems are flexible enough to switch between or combine both models, depending on how your product roadmap and market demand evolve.
Do you package the final product?
Final product packaging is part of our standard box build scope. We handle everything from internal fitment and accessories to custom labels, inserts, and outer packaging as per your specs. Whether it’s retail-ready or bulk-packed for B2B, we ensure each unit is fully assembled, tested, and packed exactly the way you need, so it’s ready to ship without additional handling at your end.
Do you offer packaging design services?
We don’t offer packaging design as a standalone service. However, we can support execution based on your provided design, including sourcing materials, custom inserts, labeling, and assembly. If you need minor adjustments for manufacturability or fit, our team can help refine the packaging during production, but the core design should come from your end.
Do you offer white-labelling when shipping products directly to our customers?
Yes, we support white-labelling when shipping products directly to your customers. We can use your branded packaging, labels, documentation, and shipping instructions, ensuring the end customer receives a seamless brand experience. Our team follows strict handling protocols to maintain confidentiality, so your product looks and feels like it came directly from you, not a manufacturing partner.
