Running Cost 1
: Specialized Payroll
Payroll Reality Check
Your 35 FTEs in 2026 will cost $23,417 per month in specialized payroll, covering technicians and management. Honestly, this is heavy fixed cost until revenue scales. You must drive technicians to hit 65 billable hours per customer monthly just to cover this staff expense efficiently.
Cost Inputs
This $23,417 payroll covers all 35 full-time equivalents (FTEs), splitting between high-skill technicians and management staff. To justify this spend, you need to map technician time against the required 65 billable hours target for every customer account monthly. What this estimate hides is the required utilization rate needed to make those 35 people profitable.
Fixed staff cost: $23,417/month
Target utilization: 65 hours per customer
Staff mix: Technicians plus management
Maximize Billable Time
Manage this cost by obsessing over technician utilization. Every hour spent not generating revenue-traveling inefficiently or waiting for parts-eats into your margin. Focus on routing software to cut drive time. If technicians average only 55 billable hours, you'll need more customers just to cover the existing payroll gap, defintely increasing risk.
Cut non-billable drive time first
Tie scheduling to customer density
Improve dispatch accuracy daily
Scheduling Lever
Since payroll is fixed, your primary lever is scheduling density. Aim for technician routes that service multiple customers within a tight geographic area, maximizing the number of jobs completed before needing to drive across town. This directly boosts effective hourly rates.
Running Cost 2
: Spare Parts Procurement
Parts Cost vs Sales
Spare parts procurement is your biggest immediate threat to cash flow, hitting 180% of revenue in 2026. This ratio means you're buying $1.80 in components for every $1.00 you bill customers. Effective inventory control isn't optional; it's survival to keep cash available for payroll and overhead.
Parts Cost Calculation
This line item covers all replacement components-motors, sensors, and circuit boards-required for service calls. You calculate this by applying the 180% factor directly to your projected 2026 revenue figure. What this estimate hides is the timing: parts must be bought before invoicing, straining working capital.
Apply 180% to 2026 revenue.
Track component cost per job.
Watch cash burn defintely.
Managing Parts Inventory
You must manage availability versus cash drain. Focus on high-turnover, low-value items for safety stock, but use just-in-time ordering for expensive, specialized components. Negotiating Net 30 or Net 45 payment terms with suppliers is crucial to delay cash outflow when servicing clients.
Negotiate supplier payment terms.
Use JIT for costly parts.
Avoid stocking slow movers.
Cash Flow Priority
This 180% ratio makes inventory financing your main operational challenge, not service delivery itself. If you can't shift supplier terms, you need external funding specifically earmarked to cover the gap between buying parts and receiving payment from labs.
Running Cost 3
: Facility Rent
Fixed Facility Overhead
Facility rent is a fixed overhead of $4,500 per month. This space isn't just office area; it must securely house specialized repair equipment and inventory of critical spare parts needed for rapid service calls to keep labs running.
Cost Inputs
This $4,500 covers the workshop floor plan and secure office space. Since it's fixed, it must be covered regardless of service volume. It directly impacts your break-even calculation, sitting alongside payroll and insurance as essential overhead. We defintely need enough space for calibration equipment.
Fixed monthly cost: $4,500.
Covers specialized equipment footprint.
Requires secure storage compliance.
Managing Rent Risk
Reducing this cost means finding smaller locations, but that risks insufficient space for specialized tools or inventory security. Don't sacrifice secure parts storage for a few hundred dollars saved; inventory loss is far costlier. A common mistake is underestimating the required square footage for calibration zones.
Avoid sacrificing security for savings.
Factor in specialized equipment needs.
Check zoning for workshop use.
Utilization Check
Because this is a fixed cost, operational efficiency hinges on maximizing technician utilization within this footprint. If technicians spend too much time managing inventory instead of repairing centrifuges, this $4,500 expense is not being fully utilized to generate billable revenue for the service business.
Running Cost 4
: Professional Insurance
Insurance Reality Check
This insurance is mandatory for your high-stakes repair work. Budget exactly $1,100 monthly for Professional Liability Insurance. This covers mistakes made while servicing critical laboratory centrifuges, protecting against claims resulting from equipment failure after your team leaves the site. It's a fixed overhead you can't skip.
Liability Coverage Scope
This $1,100/month policy shields the business when technical errors occur during complex centrifuge repairs. You need to confirm the coverage limits match the replacement cost of the most expensive equipment you service, like high-speed models. It sits alongside your $4,500 rent as essential fixed overhead, not a variable cost tied to sales volume. Anyway, this is critical.
Covers errors in diagnosis.
Protects against sample loss claims.
Fixed monthly expense.
Managing Premium Risk
You can't cut this cost, but you can manage the risk profile driving the premium. Ensure technicians complete required Manufacturer Certification training annually. A clean claims history over 18 months helps negotiate renewal rates. Don't skimp on coverage limits just to save a few dollars monthly; the downside risk is catastrophic. We see too many startups defintely underinsure.
Mandate ongoing tech training.
Review coverage annually.
Keep claims history clean.
Fixed Cost Impact
Since this is a fixed cost, it directly pressures your early-stage profitability. If you start with 35 FTEs and payroll is $23,417/month, this $1,100 insurance adds 4.7% to your baseline payroll burden before factoring in any revenue. Focus on driving billable hours immediately to absorb this fixed overhead.
Running Cost 5
: Customer Acquisition Marketing
CAC Strategy
Marketing starts lean in 2026 at $25,000 annually, aiming for a $550 Customer Acquisition Cost (CAC). This budget must efficiently land those crucial, high-value laboratory contracts needed to cover high variable costs later on.
Acquisition Math
This initial $25,000 spend in 2026 funds lead generation aimed at securing contracts from biotech firms or research centers. To hit the $550 CAC target, you need to know how many new labs you must sign. Here's the quick math: that budget buys about 45 new customers in the first year.
Budget starts at $25,000 for 2026.
Target CAC is $550 per lab contract.
This buys about 45 new customers annually.
Managing High Costs
Since field logistics eat up 90% of revenue, every marketing dollar must deliver a high Lifetime Value (LTV). Focus spend on channels that reach decision-makers responsible for large, multi-year maintenance agreements, not just one-off repairs. Don't defintely waste money chasing low-volume leads.
Prioritize LTV over quick wins.
Measure channel spend against contract size.
Avoid broad, untargeted outreach.
Payroll Context
Don't confuse this marketing spend with payroll; $23,417 monthly payroll covers 35 full-time employees (FTEs). If marketing doesn't fill the service pipeline quickly, those technicians sit idle, making the $550 CAC target even more critical to hit fast.
Running Cost 6
: Field Operations Logistics
Logistics Eats 90%
Your field operations are the single largest cost center, combining Technical Logistics at 50% and Vehicle Fuel at 40% of revenue. Every minute wasted driving between labs directly erodes margin, making scheduling optimization the top priority for financial health.
Cost Breakdown
This 90% expense covers getting your 35 technicians to client sites. Inputs needed are total monthly revenue multiplied by 0.50 for logistics and 0.40 for fuel. Remember, this cost scales perfectly with service volume, unlike fixed rent.
Calculate fuel based on miles driven.
Logistics covers routing software spend.
Track technician time per job site.
Routing Gains
Optimize routes to maximize the 65 billable hours per customer. Inefficient scheduling means you are paying $23,417 in monthly payroll for non-billable drive time. Focus on zip code density to cut fuel usage defintely.
Cluster service calls geographically.
Use software to minimize deadhead miles.
Negotiate fleet fuel card discounts.
Margin Impact
A 10% swing in logistics efficiency-say, moving from 90% to 80% of revenue-is pure profit leverage. This is far more immediate than trying to cut the massive 180% spare parts cost right now.
Running Cost 7
: Management Software
Field Software Cost
You need dedicated Field Service Management Software to run Apex Scientific Services efficiently. This system costs $650 per month. It handles scheduling, dispatching technicians, and tracking critical inventory movements in real-time. Without this, managing 35 technicians and optimizing billable time becomes nearly impossible.
Budgeting the Platform
This $650 monthly fee covers the core platform needed for field operations. You must budget this fixed cost against the $23,417 in monthly payroll for 35 staff. The system tracks technician utilization against the 65 billable hours per customer per month target. It's a necessary operational fixed overhead.
Fixed monthly subscription cost.
Supports technician time tracking.
Essential for real-time inventory updates.
Controlling Software Spend
Don't pay for excessive features you won't use. Start small and scale licenses based on actual technician count, not projections. A common mistake is paying for modules related to sales quoting when you only need dispatching. Negotiate annual contracts for a slight discount, maybe saving 5% to 10% annually.
Tie license count to active technicians.
Audit unused features quarterly.
Avoid paying for sales modules initially.
Operational Link to Cost Control
Poor scheduling directly inflates your 90% revenue share in logistics and fuel costs. If routing is inefficient, technicians waste time driving, not fixing centrifuges. This software must optimize routes daily to control those high variable expenses, which is defintely a major cash flow risk.
