How to Calculate Profit Margins on White Label Development Projects
Your agency has a client who wants a new website.
You've discussed the requirements, reviewed the designs and found a development partner who can handle the technical work.
The client is ready for a quotation.
Now you need to decide what to charge.
You know the development partner's price, but that isn't your agency's total cost.
You'll also spend time managing the client, reviewing the website, coordinating revisions and preparing the final handover.
If you price the project using only the developer's quotation, you may earn much less than expected.
This is one of the most important parts of running a profitable web design or digital agency.
Your selling price needs to account for the complete cost of delivering the project, not just the outsourced development work.
In this guide, we'll explain how to calculate profit margins on white label development projects, identify costs agencies often overlook and build quotations that make commercial sense.
We'll also provide practical formulas, worked examples and a reusable project pricing template.
What Is Profit Margin in White Label Development?
Profit margin measures how much of your agency's project revenue remains after accounting for the relevant costs.
For an outsourced website project, those costs may include:
- External development fees
- Internal design work
- Project management
- Quality assurance
- Content preparation
- Third-party project expenses
- Other directly attributable delivery costs
There are different ways to measure profitability.
Two particularly useful measures are project gross margin and net profit margin.
Project Gross Margin
Project gross margin measures the percentage of project revenue remaining after deducting direct project delivery costs.
For example:
Your agency charges £4,000 for a website.
The direct costs of delivering the project total £2,600.
Your project gross profit is:
Your project gross margin is:
This means 35% of the project's revenue remains after the direct delivery costs included in the calculation.
It doesn't necessarily mean your agency has earned £1,400 in net profit.
You may still need to cover general business overheads, financing costs and taxes.
Net Profit Margin
Net profit margin considers the broader expenses associated with running the business.
These may include:
- Office costs
- General software subscriptions
- Administration
- Business development
- Accounting
- Other operating expenses
- Applicable taxes
Net profit is generally assessed at the business level, although agencies may also allocate overheads to individual projects for management reporting.
For project pricing decisions, direct project margin is a useful starting point.
Profit Margin vs Markup: What's the Difference?
Profit margin and markup are often confused.
They aren't the same.
Markup is calculated as a percentage of cost.
Margin is calculated as a percentage of selling price.
Suppose a project costs your agency £2,000 to deliver and you charge the client £3,000.
Your profit before other expenses is £1,000.
Markup Calculation
Markup = Profit ÷ Cost × 100
£1,000 ÷ £2,000 × 100 = 50% markup
Margin Calculation
Margin = Profit ÷ Revenue × 100
£1,000 ÷ £3,000 × 100 = 33.3% margin
A 50% markup does not produce a 50% profit margin.
This distinction matters when setting project prices.
How to Calculate the Selling Price for a Target Margin
If you know your expected project cost and desired gross margin, you can calculate the required selling price.
The formula is:
The target margin must be expressed as a decimal.
For example, a 40% target margin becomes 0.40.
Suppose your expected direct project costs are £3,000.
You want a 40% gross margin.
Selling price:
£3,000 ÷ (1 − 0.40)
£3,000 ÷ 0.60 = £5,000
At that price:
- Client revenue: £5,000
- Direct project costs: £3,000
- Project gross profit: £2,000
- Gross margin: 40%
This is a pricing calculation, not a recommendation that every agency should target a 40% margin.
Your appropriate margin depends on your business costs, risk, market, positioning and financial goals. Review our White Label Development Pricing model for baseline calculations.
1. Start With the White Label Development Cost
The first cost to identify is the development partner's quotation. For an in-depth breakdown of pricing components, consult our White Label Development Cost Guide.
This may cover:
- WordPress development
- Shopify development
- WooCommerce implementation
- Frontend development
- Backend development
- Custom functionality
- API integrations
- Testing
- Launch support
However, the quotation may not include every activity your agency expects.
For example, a WordPress development quote might include the implementation of approved designs but exclude:
- Website copywriting
- Content uploads
- Paid plugin licences
- Third-party subscriptions
- Additional functionality
- Ongoing maintenance
Review the inclusions and exclusions before using the quote in your pricing calculation.
A development price is only useful when you understand what it covers.
2. Include Your Agency's Internal Delivery Costs
Outsourcing development doesn't eliminate internal work.
Your agency may still handle:
- Discovery calls
- Requirements gathering
- Website design
- Client communication
- Project planning
- Internal reviews
- Quality assurance
- Client feedback
- Launch coordination
These activities consume staff time.
Even if the agency owner completes them personally, that time has an economic cost.
Example Internal Cost Calculation
Suppose your team expects to spend:
| Activity | Estimated hours | Internal cost per hour | Total |
|---|---|---|---|
| Project management | 12 | £25 | £300 |
| Design review | 8 | £30 | £240 |
| Quality assurance | 6 | £25 | £150 |
| Client communication | 5 | £25 | £125 |
| Total | 31 | - | £815 |
These are hypothetical internal cost figures, not market rates.
Your agency should use its own employment, contractor or internal costing data.
Avoid Confusing Cost With Billing Rate
If your agency charges clients £80 per hour for design work, that doesn't necessarily mean your internal cost is £80 per hour.
For profitability calculations, use an appropriate cost basis.
For quotations, consider the value and price of the service separately.
3. Account for Third-Party Expenses
Website projects sometimes require paid tools and services.
Examples include:
- Premium themes
- Paid plugins
- Shopify apps
- Stock images
- Specialist integrations
- External testing services
- Other project-specific licences
Some expenses are paid directly by the client.
Others may be included in your agency's project price.
Make sure you know which applies.
For example, if the client pays directly for its Shopify subscription, don't automatically count that subscription as an agency expense.
But if your agency purchases a paid integration as part of the project, include the relevant cost.
Recurring subscriptions should also be identified so the client understands ongoing responsibilities.
4. Allow for Project Risk and Uncertainty
Not every project runs exactly as planned.
Common sources of additional work include:
- Unclear requirements
- Incomplete content
- Unexpected platform limitations
- Third-party integration problems
- Additional testing
- Client approval delays
- Technical dependencies
- New functionality requests
Your agency can account for foreseeable uncertainty when preparing the quotation.
One approach is to include an internal contingency allowance.
For example, you might estimate additional delivery costs for a project with incomplete requirements.
However, contingency should not replace clear scope management.
If the client requests a major new feature, that may require a formal change request rather than using up the entire contingency.
Contingency Is Not Automatically Profit
If the allowance is spent, it becomes a project cost.
If it isn't spent, it may contribute to the project's final margin.
Track the actual costs rather than treating contingency as guaranteed earnings.
5. Calculate the Full Cost of a White Label Website Project
Let's look at a hypothetical agency project.
A client needs a redesigned WordPress website.
The agency handles design, client communication and project management.
An external development partner completes the agreed WordPress implementation.
Example Project Cost Breakdown
| Cost item | Amount |
|---|---|
| White label WordPress development | £1,800 |
| Internal design work | £600 |
| Project management | £350 |
| Quality assurance | £200 |
| Third-party project expenses | £150 |
| Contingency allowance | £300 |
| Estimated project cost | £3,400 |
The £300 contingency is included as a planned allowance, not an expense already incurred.
Suppose the agency wants to price the project for a 35% gross margin on this estimated cost.
Selling price:
£3,400 ÷ (1 − 0.35)
= £3,400 ÷ 0.65
= £5,230.77
The agency might use a rounded quotation, depending on its commercial strategy.
At a selling price of £5,250:
| Measure | Amount |
|---|---|
| Client price | £5,250 |
| Estimated project cost | £3,400 |
| Estimated project gross profit | £1,850 |
| Estimated gross margin | 35.24% |
These figures are illustrative.
They aren't suggested market prices for WordPress development.
6. Calculate Margins for Shopify Projects
Shopify projects may have different cost considerations.
For example, a store development project could involve:
- Theme implementation
- Product templates
- Collection templates
- App configuration
- Payment and shipping setup
- Integrations
- Ecommerce testing
- Launch coordination
Some tasks may be completed by the development partner through White Label Shopify Development.
Others may remain with the agency or client.
Example Shopify Project
| Item | Amount |
|---|---|
| Client price | £7,000 |
| Outsourced development | £3,200 |
| Internal project delivery | £1,000 |
| Other direct expenses | £400 |
| Total direct cost | £4,600 |
| Project gross profit | £2,400 |
Gross margin:
Again, this is a hypothetical example.
The important point is to calculate the margin using the complete direct delivery cost, not only the Shopify developer's fee.
7. Understand How Revisions Affect Profitability
Revisions are a normal part of website development.
But repeated changes can reduce project margins if they require additional work.
Suppose your agency expects a project to cost £3,000 and sells it for £5,000.
The planned gross margin is:
Now suppose unplanned work adds £700 in direct costs.
The final cost becomes £3,700.
The final gross margin is:
The project still generates a positive gross profit, but its margin has declined substantially.
How Agencies Can Manage Revision Costs
- Use approved designs
- Prepare clear development briefs
- Define included revisions
- Separate defects from new requirements
- Consolidate client feedback
- Confirm additional work before implementation
- Track actual time and expenses
A reliable revision process protects both project quality and profitability.
8. Don't Forget Project Management Costs
Agency owners sometimes calculate profitability using only supplier invoices.
This can make a project appear more profitable than it really is.
For example:
- Your agency charges £4,000.
- The development partner charges £2,000.
- At first glance, you have £2,000 remaining.
But suppose your team spends another £900 on project management, design review and quality assurance.
Your direct project profit is now £1,100.
Gross margin:
That's very different from the apparent 50% margin calculated using only the development invoice.
9. Consider Payment Terms and Cash Flow
A project can be profitable on paper and still create cash flow problems.
For example, your development partner may require payment before work begins.
Your client may pay in milestones or after completion.
If the payment schedules don't align, your agency may need to finance delivery.
Before starting, review:
- Client deposit requirements
- Development partner payment milestones
- Approval conditions
- Final payment terms
- Third-party expenses
- Potential delays
A practical payment structure should reflect project risk and your agency's cash position.
Example Milestone Structure
For illustration, an agency might arrange:
- Initial payment before work begins
- Payment after an agreed development milestone
- Final payment at an agreed acceptance stage
The specific percentages and timing should be negotiated and documented.
10. Choose Between Fixed-Price and Time-Based Outsourcing
The outsourcing model can affect how your agency prices its client projects. For a detailed comparison of models, see our guide on Project-Based vs Dedicated Developers.
Fixed-Price Development
This can be useful when the scope is clear.
Your agency receives a quotation for defined deliverables.
However, additional requirements may create extra costs.
Time-Based Development
This can be useful when requirements evolve.
Your agency pays for agreed time or capacity.
However, the final cost may be less predictable unless there are suitable controls.
Dedicated Developer Arrangements
Dedicated developer arrangements and Dedicated Development Support may suit agencies with consistent development work.
The agency should evaluate how much of the agreed capacity it expects to use.
The best option depends on the project pipeline and management process.
11. Compare Estimated and Actual Profit Margins
Your original quotation is a forecast.
After the project finishes, compare it with what actually happened.
| Measure | Estimated | Actual |
|---|---|---|
| Client revenue | £5,000 | £5,000 |
| Development cost | £2,000 | £2,100 |
| Internal delivery cost | £800 | £1,050 |
| Other direct expenses | £200 | £250 |
| Total direct cost | £3,000 | £3,400 |
| Gross profit | £2,000 | £1,600 |
| Gross margin | 40% | 32% |
The project was still profitable on a direct-cost basis.
However, its final margin was eight percentage points lower than planned.
Reviewing these differences can help improve future quotations.
12. Track Profitability by Project Type
Different services may have different cost structures.
Your agency might deliver:
- WordPress websites
- Shopify stores
- WooCommerce development
- Landing pages
- Website redesigns
- Custom software
- API integrations
Track costs and margins separately where practical.
For example, you may discover that small website projects require more client management than expected.
Or you may find that certain types of integrations regularly need additional technical investigation.
Use this information to improve project scoping and pricing.
Avoid assuming that the same markup or margin is appropriate for every service.
13. When Should an Agency Increase Its Project Price?
A higher quotation may be justified when the project involves:
- Complex functionality
- Significant design work
- Tight delivery requirements
- Multiple integrations
- Extensive content migration
- Additional testing
- Complex stakeholder approvals
- Higher delivery risk
The price should reflect the scope, value, commercial context and resources required.
However, increasing prices doesn't automatically improve profitability if delivery costs also increase.
Track both revenue and costs.
14. How White Label Development Can Support Agency Profitability
White label development can allow agencies to sell technical services without building every capability internally.
For example, a branding agency may manage website strategy and design while outsourcing WordPress development.
An SEO agency may handle search strategy while outsourcing technical implementation.
An ecommerce agency may outsource Shopify customisation when its internal team lacks capacity.
Potential advantages include:
- Access to additional technical skills
- Flexibility for project-based work
- Reduced need to recruit for every specialist requirement
- Ability to manage multiple client projects
- More predictable quotations when requirements are clear
However, outsourcing isn't automatically more profitable.
Your agency still needs to manage supplier costs, project scope, quality and client expectations.
The commercial value depends on how well the arrangement fits your workload and pricing.
White Label Development Profit Margin Calculator
Use this simple template before quoting a client.
Step 1: Enter Expected Project Revenue
Client selling price: £________
Step 2: Estimate Direct Project Costs
| Cost category | Your estimate |
|---|---|
| Outsourced development | £________ |
| Internal design | £________ |
| Project management | £________ |
| Quality assurance | £________ |
| Content work | £________ |
| Third-party expenses | £________ |
| Other direct costs | £________ |
| Contingency allowance | £________ |
| Total estimated cost | £________ |
Step 3: Calculate Estimated Gross Profit
Estimated gross profit = Client price − Total estimated cost
Step 4: Calculate Estimated Gross Margin
Estimated gross margin = Estimated gross profit ÷ Client price × 100
Step 5: Calculate Price From a Target Margin
Required selling price = Total estimated cost ÷ (1 − Target margin)
For example, if the estimated cost is £2,500 and the target margin is 30%:
£2,500 ÷ 0.70 = £3,571.43
This gives a mathematical starting point for your quotation.
Your final price should also consider client value, competition, risk and your agency's commercial position.
Five Questions to Ask Before Sending a Website Development Quote
1. Have we included every direct delivery cost?
Check development, design, management, testing and project-specific expenses.
2. Is the development scope clear?
Make sure the provider's quote covers the work your client expects.
3. What happens if the client requests additional functionality?
Agree on a change request process.
4. Does the payment schedule work for our agency?
Consider when you need to pay suppliers.
5. What margin will remain if the project takes longer than expected?
Test the quotation against reasonable cost increases.
These questions can help identify weak quotations before they're sent to clients.
Common Pricing Mistakes Agencies Make
Adding a Percentage Only to the Developer's Fee
This can ignore the agency's other delivery costs.
Confusing Markup With Margin
A 30% markup doesn't create a 30% margin.
Forgetting Internal Staff Time
Project management and quality assurance still cost money.
Including Unlimited Changes Without Planning for Them
Uncontrolled scope changes can reduce profitability.
Treating Contingency as Guaranteed Profit
Contingency may be needed to cover unexpected work.
Ignoring Cash Flow
Supplier and client payment schedules can create financial pressure.
Never Reviewing Actual Project Costs
Without reviewing completed projects, the agency may repeat the same pricing mistakes.
Frequently Asked Questions
What is a good profit margin for white label development?
There is no universal margin that suits every agency. The appropriate target depends on direct costs, overheads, risk, pricing strategy and business goals.
How do you calculate profit margin on outsourced web development?
Subtract direct project costs from client revenue, divide the result by client revenue and multiply by 100.
Is markup the same as profit margin?
No. Markup is based on cost, while margin is based on revenue.
Should project management be included in website pricing?
Yes. Project management consumes resources and should be considered when calculating delivery costs.
Can agencies make money outsourcing WordPress development?
Yes, if the client price exceeds the relevant costs. Actual profitability depends on the project and agency's cost structure.
Is outsourcing Shopify development profitable?
It can be. Agencies need to account for development, internal work, integrations, testing and other relevant costs.
Should agencies charge separately for revisions?
The agreement should define included revisions and how additional work is priced. Not every revision requires an extra charge.
Does hiring dedicated developers improve margins?
It may improve cost efficiency when capacity is consistently used, but unused capacity can increase effective costs.
Should agencies include a contingency in website quotations?
A reasonable contingency can help account for foreseeable uncertainty. The amount should reflect the project's risks rather than an arbitrary percentage.
How often should agencies review project profitability?
At minimum, compare estimated and actual costs when a project is completed. Longer projects may benefit from milestone reviews.
