Spare Parts and Repair Networks in India
Repair is a supply chain, not a helpline. Which parts to hold, how long to hold them, and whether to run service in-house or through partners.
- Stock the failure list, not the bill of materials. In most durable categories eight to twelve part numbers cover 70 to 80 percent of all repairs.
- Commit five to seven years of parts availability after a model is discontinued, and place a final buy sized on remaining installed base when you retire it.
- Hold parts fill rate at 95 percent and first-time fix rate at 80 to 85 percent, or turnaround targets collapse regardless of engineer headcount.
- Total service cost of 2 to 5 percent of net sales is normal. Below 2 percent usually means claims are being refused rather than resolved.
A durable goods brand that cannot repair its own product is renting customers. Service decides repeat purchase in these categories, and in India it is mostly a network design problem rather than a technical one.
Which parts to stock, and for how long
Do not stock the bill of materials. Stock the failure list.
Take twelve months of claim data and rank part numbers by consumption. In most durable categories the top eight to twelve part numbers cover 70 to 80 percent of all repairs. Those get real stock at the servicing locations. Everything else moves to order-on-demand from the factory, with a longer turnaround stated openly.
Sizing follows the same logic as any other inventory decision. Installed base times annual failure rate for that part, divided by twelve, gives monthly consumption. Multiply by supplier lead time in months and add cover for variance. For an imported part on a ninety day lead time that number will look uncomfortable. Plan it anyway, because a ninety day wait on a part is a refund request in practice.
Duration is a commercial promise. The working norm for consumer durables is five to seven years of parts availability from the date a model is discontinued. Announce it and mean it. When you retire a model, place a final buy: estimate the remaining installed base, apply the failure rate across the promised years, and order the tail in one go. Retiring a model without a final buy is how brands end up stripping returned units for parts.
Service partners versus in-house
Both models work. They fail differently.
- In-house gives you control of quality, data and customer experience. It costs salary, tooling and rent per city, so it only makes sense where you have density.
- Authorised service partners give you pin code coverage on day one at a variable cost per ticket. You give up consistency and visibility.
- Most brands settle into a hybrid: own centres in the top three to five cities that carry about half the installed base, partners everywhere else.
- For low value items there is a fourth option, which is no repair at all. Replace and scrap.
If you use partners, pay on outcomes rather than visits. A flat rate per closed ticket with a penalty for repeat visits on the same complaint aligns them to first-time fix. Audit a sample of closed tickets every month by calling the customer directly. Partner-reported closure rates are always better than the truth.
Turnaround time is the number customers judge you on
Set separate clocks and publish all of them.
- First response: within 24 hours of the complaint being raised.
- Engineer visit or carry-in slot: 48 to 72 hours in metros, 5 to 7 days in tier 2 and beyond.
- Closure where the part is in stock: within 5 days end to end.
- Closure where the part must be ordered: give a real date rather than an open-ended wait.
Two internal metrics decide whether those numbers hold. Parts fill rate, the share of tickets where the required part was available at the servicing location on the first attempt, target 95 percent. And first-time fix rate, the share of tickets closed on the first visit, target 80 to 85 percent. Below those levels, turnaround collapses no matter how many engineers you add.
Right to repair is moving, and it changes your disclosures
The Department of Consumer Affairs runs the Right to Repair Portal India, covering automobiles, consumer durables, mobiles and electronics, and farming equipment. More than sixty brands are listed, among them Apple, Samsung, LG, Panasonic, Havells, Boat, Hero MotoCorp and Mahindra. The portal carries product manuals, repair videos, spare part prices and warranty terms, plus information on authorised and third party repairers.
There is no hard statute yet compelling parts supply to independent technicians. The direction is settled though. Committee work has consistently pointed at parts, tools and diagnostic information being made available beyond the authorised network.
Readiness looks like this. Publish a spare parts price list. Publish service manuals, or at minimum exploded diagrams. Avoid design choices that make repair impossible, such as glued assemblies where screws would do, or serialised parts that refuse to pair with a replacement. Register on the portal and keep the entry current.
Repairability shows up in reviews and repeat purchase
Go read your one and two star reviews and tag them by root cause. In durable categories a large share are not about the product failing. They are about what happened after it failed: no response, no part, no date. That is a service defect being recorded as a product defect, and it drags the rating that drives conversion for every future buyer.
Fixing service moves two numbers. Rating recovers, because a well handled repair often produces a revised review when you ask for one. And repeat purchase improves, because a customer whose product was fixed inside a week now has evidence the brand is real.
Cost it honestly. Total service cost, meaning parts, labour, freight and the service team, usually lands at 2 to 5 percent of net sales for a durables brand running properly. Under 2 percent normally means claims are being refused rather than resolved, and that shows up later in ratings. Above 5 percent means the product needs fixing, not the network.
