Key Takeaways
- The fixed monthly operating budget for the B2B business averages $67,154 in 2026, excluding variable costs of goods sold.
- A minimum cash reserve of $529,000 is required to cover operating deficits until the projected breakeven point in September 2026.
- Payroll is the largest fixed expense category, consuming approximately $38,854 monthly across the initial team structure.
- The initial Customer Acquisition Cost (CAC) is high at $450, requiring a planned annual marketing spend of $150,000.
Running Cost 1 : Payroll and Benefits
Payroll Anchor
Wages are your largest fixed cost, averaging $38,854 monthly by 2026, supporting 325 FTEs. This means operational efficiency must outpace headcount growth, or you’ll quickly run out of breathing room. That’s a lot of fixed commitment.
Cost Inputs
This $38,854 estimate covers base pay for 325 roles, including the CEO, Head of Sales, and Operations Manager. To budget benefits correctly, you need quotes for employer-side taxes and health insurance premiums. This figure doesn't include the 25% to 40% uplift for benefits and payroll taxes.
- Finalize salary bands for all 325 roles.
- Obtain actual quotes for health coverage.
- Project payroll tax rates for 2026.
Controlling Headcount
Since payroll is fixed, you must resist hiring based on future projections alone. Every new hire means immediate, non-negotiable overhead that revenue must cover. If onboarding takes 14+ days, churn risk rises because productivity stalls. Focus on maximizing output per existing employee first.
- Stagger hiring based on confirmed sales targets.
- Cross-train existing staff aggressively.
- Require executive sign-off for every new requisition.
Fixed Cost Risk
If revenue slows down in 2026, this $38,854 monthly wage bill remains locked in, immediately compressing your gross margin. You need clear, predictable revenue streams to support this scale of personnel costs, defintely.
Running Cost 2 : Office and Warehouse Rent
Fixed Facility Cost
Facility costs start with a fixed $7,500 monthly rent covering both office space for your team and necessary warehouse capacity for inventory. This expense is a baseline operational commitment before factoring in variable logistics costs like outbound shipping.
Cost Breakdown
This $7,500 covers the physical footprint required for your 325 projected FTEs and the warehouse space needed to manage product flow. You need firm lease quotes to lock this down, as it’s a critical fixed overhead component alongside payroll. It's the cheapest facility cost you'll see initially.
- Covers office and warehouse space.
- Input: Signed lease agreement terms.
- Fixed monthly commitment.
Optimization Tactics
Since rent is fixed, optimization hinges on avoiding over-committing early on. If inventory volume spikes, avoid signing long-term extensions right away. Look into flexible warehouse leasing or shared space agreements to manage risk until order density is defintely stable.
- Avoid long-term leases initially.
- Right-size space based on headcount.
- Negotiate tenant improvement allowances.
Operator View
While $7,500 seems large, compare it to your $38,854 monthly payroll commitment. Facility costs are secondary to headcount in the fixed cost structure. If you delay hiring, you can defer needing the full warehouse footprint, saving on future square footage costs.
Running Cost 3 : Customer Acquisition Costs (CAC)
CAC Budget Reality
Your 2026 marketing spend is set at $150,000 annually, or $12,500 monthly, to fund customer growth. This budget must support an initial $450 Customer Acquisition Cost (CAC). You need volume fast if you plan on hitting payroll targets.
Funding New Buyers
This $150,000 marketing allocation covers all efforts to bring new buyers onto your platform in 2026. To justify this spend, you need to know how many customers you expect to acquire monthly. If you spend $12,500 to acquire customers at $450 CAC, you can onboard aboot 27.8 new customers per month (12,500 / 450).
- Budget covers all acquisition channels.
- Monthly spend target is $12,500.
- Initial cost per customer is high.
Reducing Acquisition Pressure
A $450 CAC is steep for a B2B platform relying on recurring revenue. The focus must shift quickly from acquisition to retention to improve Customer Lifetime Value (CLV). You must cut variable costs like Shipping (40% of revenue) and Payment Fees (25% of revenue) to absorb high initial marketing costs.
- Prioritize retention immediately.
- Negotiate lower logistics fees.
- Boost average order value.
CAC and Fixed Costs
If customer onboarding takes too long, churn risk rises fast, wasting that initial $450 investment. Since Payroll is $38,854 monthly, you need rapid revenue generation to cover fixed overhead before marketing spend drains working capital. Thats the reality check.
Running Cost 4 : Cost of Goods Sold (COGS)
COGS Starts Above 100%
Your initial Cost of Goods Sold structure means you lose money on every sale before factoring in operating expenses. In 2026, product costs are pegged at 100% of revenue, compounded by another 30% for logistics. This 130% initial gross margin rate requires immediate structural correction to achieve profitability.
Initial Cost Breakdown
This initial COGS calculation covers two distinct buckets for 2026. The primary input is the actual Cost of Products Purchased from Suppliers, set at 100% of sales price. The secondary input is the mandatory 30% added for Inbound Logistics and Warehousing Fees. This means your baseline cost basis is 130% of top-line sales.
- Supplier cost: 100% of revenue.
- Logistics/Warehousing: 30% of revenue.
- Total initial cost: 130%.
Cutting Logistics Drag
You must aggressively negotiate supplier terms or immediately reduce the 30% logistics overhead, which is too high for a B2B distributor. Aim to bring the product purchase cost down below 65% of revenue to create a viable gross margin. Defintely look at centralizing warehousing to reduce per-unit handling fees.
- Negotiate supplier volume discounts.
- Consolidate inbound shipments immediately.
- Target a maximum product cost of 65%.
Margin Reality Check
If revenue hits $1 million in 2026, your COGS hits $1.3 million before you pay for payroll or marketing. This starting point guarantees negative cash flow unless sales volume is massive and immediate price increases are implemented. You need a target product cost near 60%.
Running Cost 5 : Software Subscriptions (SaaS)
Fixed Tech Stack
Your core technology stack costs $4,900 monthly in fixed software licenses. This covers the essential E-commerce Platform at $2,500, necessary CRM/ERP tools at $1,800, and infrastructure hosting at $600. This is a critical, non-negotiable operating expense for the B2B platform.
Stack Breakdown
This $4,900 covers the three pillars of your B2B operation. The E-commerce Platform handles sales transactions, while the CRM/ERP manages customer data and inventory flow. Hosting covers the server costs. Budgeting requires locking in annual quotes for the platform and CRM licenses, as these are fixed monthly commitments regardless of sales volume.
- Platform License: $2,500
- CRM/ERP Suite: $1,800
- Hosting/Infrastructure: $600
Cutting Software Spend
You must scrutinize the $1,800 CRM/ERP spend first; often, features go unused after initial setup. Consolidating tools or negotiating multi-year contracts can yield savings. Always audit user seats quarterly. If onboarding takes 14+ days, churn risk rises, so ensure your chosen CRM supports fast implementation.
- Audit unused CRM/ERP seats.
- Negotiate hosting discounts for commitment.
- Avoid feature creep on the platform.
SaaS Cost Stickiness
These software costs are highly fixed and hard to cut quickly once deployed. Switching major systems like the E-commerce Platform or ERP often involves significant migration expense and operational downtime, making the initial selection defintely critical for long-term stability.
Running Cost 6 : Shipping and Payment Fees
Fee Drag
Shipping and payment fees combine to consume 65% of revenue in 2026, immediately pressuring gross margin before factoring in product costs. This high variable cost structure means every dollar of revenue carries a substantial, non-negotiable cost burden that must be managed aggressively.
Variable Cost Drivers
Outbound Shipping and Packaging is set at 40% of total revenue, covering fulfillment expenses like boxes and carrier rates for delivering goods to the SMB customer. Payment Processing Fees account for the remaining 25% of revenue, covering interchange and gateway charges for accepting payments.
- Shipping: 40% of Sales
- Payments: 25% of Sales
- Total: 65% of Revenue
Cutting the Drag
Reducing this 65% drag requires negotiating carrier rates aggressively and optimizing packaging dimensions to reduce dimensional weight charges. For payments, consolidating transaction volume onto fewer processors can shave basis points off the 25% rate. You defintely need volume discounts here.
- Negotiate carrier volume tiers.
- Optimize packaging size/weight.
- Bundle payment processing deals.
Margin Reality Check
Since Cost of Goods Sold (COGS) is already 130% of revenue (product cost plus 30% inbound logistics), these variable fees push the blended gross margin deeply negative before fixed costs hit. You must secure supplier cost reductions or increase Average Order Value (AOV) significantly just to cover fulfillment expenses.
Running Cost 7 : Administrative Overhead
Admin Fixed Base
Fixed administrative costs total $2,200 monthly before factoring in payroll or rent. This baseline covers essential compliance items like legal retainers and mandatory insurance coverage. You need to budget for this floor regardless of sales volume.
Required Overhead Inputs
These costs are fixed overhead required for compliance, not tied to revenue volume. The inputs are simple: $1,500 for the Accounting and Legal Retainer and $700 for Business Insurance. This $2,200 base sits alongside rent and software costs in your operating expense structure.
- Legal/Accounting Retainer: $1,500
- Mandatory Insurance: $700
Managing Compliance Spend
Insurance at $700 is usually benchmarked; focus on the $1,500 legal retainer. Shop for flat-fee legal services instead of hourly retainers if your transactional volume is predictable. Honestly, avoid paying for unused legal access time, which is a common drain.
- Audit legal scope every quarter.
- Seek flat-fee compliance packages.
- Insurance is defintely non-negotiable.
The Absolute Cost Floor
This $2,200 is your true administrative floor; it must be covered before payroll or marketing spend hits. If revenue dips, this fixed commitment immediately pressures your contribution margin dollars, so plan for it to be covered by your first sales.
