Are You Missing Service BOM-Based Revenue? Here’s Why You Might Be
For most Industrial OEMs, the real revenue isn’t just in selling the equipment — it’s in the aftermarket. Spare parts, services, upgrades, maintenance kits — these are recurring, high-margin opportunities.
But most OEMs are leaving serious money on the table because they don’t fully leverage one key asset: their Service BOM (Bill of Materials).
Let’s look at an example:
- You sell a large machine to a customer.
- Over the next year, they spend $1M maintaining it — across spares, services, and upgrades.
- But you only capture $250K of that spend.
That’s $750K leaking out every year, just from one customer.
Where does the leakage come from?
It often traces back to gaps in BOM visibility and utilization:
- You don’t know what parts are installed on each asset
- You can’t track which components haven’t been replaced in years
- You don’t know when third-party or non-OEM parts are being used
- You’re not running targeted campaigns based on asset lifecycle or part history
Let’s do the math:
Say a customer has 500 assets.
Each has a BOM of 40 parts → 20,000 total parts
Even a modest 10% replacement rate/year = 2,000 parts replaced
At $200 per part average = $400,000/year opportunity
If you only capture 30% of that due to poor BOM usage — you’re losing $280,000 per year per customer.
The Wallet Share Problem for Industrial OEMs
Your installed base is massive. Your customers need spare parts, service, maintenance, and upgrades.
But here’s the catch — not all of that spend is coming to you.
That’s where wallet share comes in. It’s the % of your customer’s total aftermarket spend (on parts/services) that you, the OEM, actually capture.
Let’s break it down:
Your customer spends $1M/year on maintaining your equipment
You only get a small pie of it.
The rest? Goes to third-party vendors, unauthorized suppliers, or is missed entirely.
In short, you’re missing out on a large chunk of your real revenue.
How Entytle’s Service BOM Feature Helps You Capture More
Your Service BOM isn’t just a documentation tool — it’s a powerful revenue enabler. Here’s how:
1. See What’s Installed — and What’s Missing
With Entytle’s structured Service BOM linked to each asset:
- You know exactly what components are in use
- You can identify what parts customers haven’t ordered recently
- You can infer where they’re likely sourcing parts elsewhere
✅ Action: Proactively target those gaps with OEM replacement offers.
2. Run Hyper-Targeted Campaigns
Using BOM + purchase data + install base:
- Find parts not purchased in the last X months
- Flag assets using obsolete or non-OEM parts
- Focus outreach on high-value, high-risk components
✅ Action: Equip sales and marketing with data-driven campaign targets.
3. Offer Bundles, Not Just Parts
BOM visibility enables:
- Maintenance kits
- Spare part bundles
- Upgrade kits tied to asset lifecycle
✅ Action: Boost average order value with smart, BOM-based packaging.
4. Standardize Across Sites & Customers
Compare BOMs across multiple customers or facilities:
- Spot inconsistent part usage
- Highlight non-OEM or third-party trends
- Recommend standard OEM configurations
✅ Action: Drive standardization and reclaim share across the board.
5. Identify Upgrade & Retrofit Opportunities
Service BOM data shows you:
- Assets running outdated configurations
- Parts no longer manufactured
- Machines due for retrofitting
✅ Action: Promote OEM upgrade programs and extended lifecycle packages.
Why Service BOM Works
| BOM Power | Expand share across the base |
| Full asset-part visibility | Plug revenue leaks |
| Purchase history integration | Pinpoint missed sales |
| Campaign enablement | Drive re-engagement |
| Kit & bundle creation | Increase deal size |
| Cross-customer insights | Expand share across base |
✅ The Bottom Line
Entytle’s BOM transforms how you sell parts and services:
- From reactive to proactive
- From manual to automated
- From low wallet share to maximized opportunity
