Tracking Profitability When You Subcontract

The math that makes freelance marketing consulting work eventually hits a ceiling: your skills multiplied by your available hours. Subcontracting is how you break through that ceiling — bringing in designers, copywriters, developers, and media buyers to deliver work you've sold but shouldn't (or can't) execute yourself.

But subcontracting introduces a problem most solo consultants aren't prepared for: you can be busy, billing well, and still losing money on a client. The gap between what you charge and what you keep gets harder to see as more people touch the work.

When to Subcontract (and Who)

Subcontract when the work falls outside your core expertise or when your time is worth more on strategy than execution.

Common subcontractor roles for marketing consultants:

Graphic designers: Brand assets, ad creative, social graphics, presentation decks. Typical rates: $50-$125/hour or $500-$2,000 per project.
Copywriters: Blog content, email sequences, landing page copy, ad copy. Typical rates: $75-$200/hour or $0.15-$0.50/word.
Web developers: Landing pages, site updates, tracking implementation. Typical rates: $100-$200/hour.
Media buyers: Specialized paid search or paid social management. Typical rates: $75-$150/hour or 10-15% of managed spend.
Video editors: Social content, testimonial videos, ad creative. Typical rates: $50-$100/hour.

The test: if you're spending 10 hours on design work you could subcontract for $1,000, and your strategy rate is $200/hour, you just cost yourself $1,000 in opportunity cost.

Markup vs. Pass-Through: Choosing Your Model

Pass-through (cost + management fee): You bill the subcontractor's cost at exactly what they charge you, then add a separate line item for project management, creative direction, or oversight.

Example: Designer charges you $1,500. You pass through $1,500 to the client plus a $500 management fee. Client sees both line items. Total: $2,000.

Markup: You mark up the subcontractor's cost by 15-30% and present a single line item to the client.

Example: Designer charges you $1,500. You bill the client $1,950 (30% markup). Client sees one line item for "design services." Your margin: $450.

Blended into retainer: You don't itemize subcontractor costs at all. Your $8,000/month retainer includes strategy, oversight, and all subcontracted execution. The client pays one number.

Each model has tradeoffs:

| Model | Transparency | Margin visibility | Client trust | Your upside | |-------|-------------|-------------------|--------------|-------------| | Pass-through | High | High | High | Lower | | Markup | Medium | Medium | Medium | Medium | | Blended | Low | Hardest to track | Depends | Highest potential |

For most independent marketing consultants, blended into retainer is the strongest position — but only if you're actually tracking your costs internally. Otherwise, you're flying blind.

The Margin Math You Need to Do

Here's where most consultants get sloppy. You need to know three numbers for every client, every month:

Gross revenue: What the client pays you
Direct costs: What you pay subcontractors + any hard costs (software, ad spend management tools)
Your effective rate: (Gross revenue - Direct costs) / Your hours spent

Example:

Client retainer: $8,000/month
Copywriter: $1,200/month
Designer: $800/month
Your hours: 25 hours/month
Your effective rate: ($8,000 - $2,000) / 25 = $240/hour

That looks great. Now here's what happens when scope creeps:

Client retainer: $8,000/month
Copywriter: $1,800/month (extra blog posts)
Designer: $1,200/month (extra revision rounds)
Developer: $600/month (landing page tweaks)
Your hours: 35 hours/month (more coordination, more client calls)
Your effective rate: ($8,000 - $3,600) / 35 = $126/hour

Same client. Same retainer. Half the effective rate. This is how profitable clients become unprofitable ones — gradually, then suddenly.

Tracking Subcontractor Costs Against Client Revenue

The minimum viable tracking system:

Per client, per month, record:

Total billed to client
Each subcontractor payment tied to that client
Your hours on that client
Any hard costs (tool subscriptions allocated to that client, ad platform fees)

Calculate monthly:

Gross margin: Revenue - All direct costs
Gross margin percentage: Should be 50-70% for a healthy consulting practice
Your effective hourly rate: Gross margin / Your hours

Review quarterly:

Trending up or down? A client whose margin has dropped from 65% to 45% over three months needs a conversation.
Which subcontractors are driving cost increases? Is it scope expansion or rate increases?
Are you spending more hours on coordination than you budgeted?

The Management Tax

Here's what nobody tells you about subcontracting: managing people is work, and it eats your margin.

For every subcontractor on a project, expect to spend:

1-2 hours/week on briefing, feedback, and revisions
30 minutes/week on coordination and scheduling
1 hour/week on quality review

So a client with three subcontractors isn't just costing you their fees — they're costing you 8-12 hours/week of management time. If you're not billing for that management time, it's coming straight out of your margin.

The fix: build management time into your pricing from the start. When scoping a retainer that involves subcontractors, add 20-30% to your hours estimate for coordination and oversight. If you estimated 15 hours of your own strategic work, budget 18-20 total.

When a Client Stops Being Profitable

Red flags:

Your effective rate drops below your floor rate. If your minimum is $150/hour and a client is working out to $110/hour after subcontractor costs, something needs to change.
Subcontractor costs exceed 50% of the retainer. At that point, you're essentially running a staffing agency with strategy on top. Either raise the retainer or reduce the scope.
You're spending more time managing than strategizing. If 70% of your hours on a client go to vendor coordination rather than the strategic work you were hired for, the engagement has drifted.
Scope has grown but the fee hasn't. The classic. Started at $6,000/month for strategy and content oversight. Now you're managing a designer, a developer, and a freelance social media manager — still at $6,000.

The Conversation to Have

When the numbers show a client isn't profitable, you have three options:

Raise the retainer. "Our engagement has grown significantly since we started. The current scope — strategy, content management, design oversight, and campaign management — is a $10,000/month engagement. I'd like to adjust our fee to reflect the actual scope."

Reduce the scope. "To keep us at the current fee, I'd recommend we focus on strategy and content, and have your team handle design and development directly."

Exit gracefully. Not every client is worth keeping. Give 60 days notice, document everything, and leave the relationship clean. A $6,000/month client that costs you $5,500 to service is worse than no client.

None of these conversations are comfortable. All of them are easier than quietly resenting a client for six months while your margins erode.
