Bottom line: Your agency's design-driven work deserves pixel-perfect execution. FatLab transforms design files from Figma, XD, PSD, Sketch, or any design platform into custom WordPress themes built from scratch. We work under your brand, guarantee our work, and make you look good to your clients.
The Agency Dilemma: Beautiful Designs Meet Development Reality
You've spent weeks perfecting your client's brand strategy. Your design team has created stunning mockups in Figma. Every color, every typeface, every interaction has been carefully considered. The client has approved the designs with enthusiasm.
Now comes the moment that separates successful agencies from struggling ones: turning those static designs into a live, functional WordPress website.
This is where many PR agencies, marketing firms, and design studios often encounter a challenge. Do you hire in-house WordPress developers and manage overhead? Do you cobble together freelancers and hope for consistency? Do you compromise your design vision with a commercial theme? Or do you find a white-label development partner who actually understands what design-driven agencies need?
For agencies exploring the full range of white-label WordPress partnership options, White Label WordPress Services: A Complete Guide for Agencies provides comprehensive insights into development, hosting, maintenance, and support services that can transform your agency's WordPress capabilities.
The answer matters because your reputation depends on it.
Why Commercial Themes Fail Design Agencies
Commercial WordPress themes create an impossible situation for agencies that take design seriously.
You've invested months developing a unique brand identity for your client. You've crafted a design system that perfectly expresses their values. You've presented mockups that got enthusiastic approval.
Then you discover that the "flexible" WordPress theme you purchased forces compromises at every turn:
- The layout doesn't quite match your design specifications
- Typography options are limited to the theme's preset choices
- The header functionality requires creative workarounds
- Custom sections need a page builder that adds bloat
- The mobile experience doesn't match your responsive designs
- Performance suffers under the weight of unused features
Worse, your client notices. They approved a specific design, and now they're looking at something that's "close enough." That's not what agencies build their reputations on.
Even premium page builders like Elementor or Divi force your designs into their constraints. You end up spending hours fighting with padding, margins, and built-in limitations—trying to recreate designs that should have been built exactly as specified from the start.
The Custom WordPress Theme Advantage for Agencies
Custom WordPress theme development takes a fundamentally different approach. Instead of forcing your designs into a commercial theme's limitations, custom themes are built specifically for each project, matching your approved designs pixel by pixel.
What custom theme development means for agencies:
Pixel-Perfect Accuracy
Every element matches your design files exactly. Typography, spacing, colors, layouts, interactions—everything translates directly from your approved designs to the live website. No compromises, no "close enough" solutions.
Performance Without Bloat
Custom themes contain only the code needed for your specific project. No unused features, no page builder overhead, no commercial theme bloat. This means faster load times, better Core Web Vitals, and superior SEO performance.
True Brand Expression
Your client's unique brand identity translates perfectly to their website. Custom themes capture the nuances of your design work—the subtle animations, the specific spacing, the carefully considered user experience that sets your work apart.
Maintainable and Secure
Custom themes built following WordPress best practices remain secure, compatible with future WordPress updates, and easy to maintain. No conflicts with commercial theme updates or deprecated page builder features.
Complete Control
Need a specific functionality? Custom layout structure? Unique content editing experience? Custom themes provide agencies with complete control over every aspect of the website, eliminating the constraints of commercial solutions.
From Any Design Platform to WordPress: Our Conversion Process
At FatLab, we work with design files from virtually any platform agencies use. Whether your team designs in Figma, Adobe XD, Sketch, Photoshop (PSD), or any other tool, we translate those designs into custom WordPress themes with pixel-perfect accuracy.
Figma to WordPress Theme Development
Figma has become the design tool of choice for many agencies, and we've perfected the Figma-to-WordPress conversion process. We extract all design specifications directly from your Figma files—typography, spacing, colors, components, interactions—and translate them into clean, custom WordPress code.
Unlike automated Figma-to-WordPress plugins that produce bloated, unreliable code, our developers hand-code every theme, following WordPress best practices. This ensures your designs are executed with precision while maintaining performance and security standards.
Adobe XD to WordPress Conversion
For agencies working in Adobe XD, we seamlessly convert your XD designs into fully functional WordPress themes. We understand XD's prototyping capabilities and ensure that your intended interactions and user experiences translate accurately to the final website.
PSD to WordPress Development
While Figma has gained popularity, many agencies continue to create detailed designs in Photoshop. Our PSD to WordPress conversion services maintain every detail of your layered PSD files, ensuring pixel-perfect accuracy in the final WordPress implementation.
Working with Any Design Files
Beyond the major platforms, we've successfully built WordPress themes from Sketch files, InVision prototypes, design PDFs, and even detailed wireframes combined with style guides. If you can design it, we can build it in WordPress.
White Label Partnership: Your Brand, Our Development
FatLab operates as a true white-label WordPress development partner for agencies. Your clients never know we exist—every interaction, every email, every deliverable comes from your agency.
How white label partnership works:
Invisible Execution
We work behind the scenes, handling all technical development while you maintain complete control of client relationships. Your client sees only your agency's branding and communication.
Your Choice of Involvement
Some agencies prefer us to work directly with their clients for technical discussions and gathering requirements. Others want us to be completely invisible, with all communication flowing through the agency. Either approach works—it's up to you.
Flexible Engagement Models
Engage us for individual projects, or establish an ongoing partnership where we become an extension of your team. Many agencies have worked with us on dozens of projects over the years, knowing they can consistently deliver exceptional custom WordPress development under their brand.
NDA-Protected Relationships
We sign NDAs to protect your client relationships and maintain the agency's reputation. Your proprietary information, design processes, and client details remain completely confidential.
Beyond Development: Consulting and Planning Support
While many agencies come to us with approved designs ready for development, we can also participate earlier in the project lifecycle.
Strategic Consultation
Do you need technical guidance during the planning phase? We advise on WordPress capabilities, recommend approaches for complex functionality, and help scope projects accurately before designs are finalized.
Technical Feasibility Review
Before your design team invests weeks in mockups, we can review concepts and confirm technical feasibility, identify potential challenges, and suggest WordPress-friendly approaches that align with your creative vision.
Content Structure Planning
We help agencies plan WordPress content structures that make sense for their clients—custom post types, taxonomies, and content relationships that support both the design and the client's long-term content management needs.
Performance Considerations
During planning and design, we provide guidance on performance optimization, helping agencies make design decisions that support fast-loading, high-performing websites without compromising visual quality.
The Custom Theme Development Process
Our streamlined process ensures that agencies can confidently promise timelines to their clients, knowing we'll deliver exceptional quality.
1. Project Kickoff and Planning
We start by thoroughly understanding your project requirements, design specifications, and client objectives. This includes reviewing all design files, discussing functionality requirements, and establishing clear deliverables and timelines to ensure a seamless project execution.
2. Development Environment Setup
We establish a staging environment where we build the custom theme. Agencies can log in at any time to review progress, and we provide regular updates throughout the development process.
3. Custom Theme Development
Our WordPress developers hand-code your custom theme following WordPress coding standards and best practices. This includes:
- Converting designs into clean, semantic HTML and CSS
- Building custom WordPress templates and template parts
- Developing custom post types and taxonomies as needed
- Creating intuitive content editing interfaces
- Implementing responsive designs that work flawlessly across devices
- Integrating required functionality and third-party services
- Optimizing for performance and Core Web Vitals
4. Quality Assurance and Testing
Before delivery, every custom theme undergoes rigorous testing:
- Cross-browser compatibility (Chrome, Firefox, Safari, Edge)
- Responsive design testing across multiple device sizes
- Content management testing to ensure intuitive editing
- Performance optimization and load time testing
- Security review and WordPress best practices verification
- Accessibility standards compliance (WCAG 2.1)
5. Training and Documentation
We provide comprehensive documentation and training so your client's team can confidently manage their WordPress website. This includes video tutorials, written documentation, and direct training sessions as needed.
6. Delivery and Launch Support
We deliver the completed custom theme to your agency for client review and approval. We handle any adjustments needed during the review process and provide technical support during the website launch.
Guaranteed Quality: No Revision Limits Within Scope
Unlike development firms that limit revisions or charge for changes, we guarantee our work within the defined project scope.
What this means for agencies:
Unlimited Revisions
If something doesn't match the approved designs, we make the necessary adjustments. If the client requests changes within the original scope, we implement them. We don't count revision rounds or nickel-and-dime you for adjustments.
Fixed Project Pricing
Once we agree on the project scope and price, that's what you pay. No surprise costs, no hourly overages, no "that'll be extra" conversations.
Quality Commitment
We continue working until both you and your client are completely satisfied with the final product. Our job is to make you look good to your clients, and we take that responsibility seriously.
Scope Protection
A clear scope definition at the project start protects both parties. Additions beyond the original scope are transparently discussed and priced, but our guarantee covers everything within scope.
Timeline: 2-6 Weeks from Design to Launch
Most custom WordPress theme projects are completed within 2-6 weeks, depending on complexity and scope.
Typical timelines by project type:
Simple Brochure Sites (2-3 weeks)
5-10 page websites with straightforward content structures and standard WordPress functionality.
Standard Business Sites (3-4 weeks)
10-20 page websites with custom post types, more complex layouts, and moderate custom functionality.
Complex Sites (4-6 weeks)
Large websites with extensive custom functionality, multiple custom post types, complex content relationships, third-party integrations, or membership features.
E-commerce Sites (4-6 weeks)
WooCommerce implementations with custom product templates, checkout customizations, or complex e-commerce functionality.
These timelines assume we have complete, approved designs at project start. Projects requiring our involvement in planning or design phases may have extended timelines, which we discuss during initial scoping.
Built from Scratch: No Commercial Themes, No Shortcuts
Every WordPress theme we create for agencies starts completely from scratch. We don't use commercial themes as a base. We don't start with theme frameworks. We don't rely on starter themes that come with built-in limitations.
Why starting from scratch matters:
Security and Compliance
Custom themes contain only the code needed for your specific project, reducing security vulnerabilities and making compliance audits straightforward.
Performance Optimization
Without the overhead of commercial theme features you'll never use, custom themes load faster and perform better, directly improving user experience and SEO.
Long-Term Maintainability
Clean, well-documented custom code is easier to maintain, update, and extend over the years. No dependency on commercial theme developers who might abandon products or change direction.
WordPress Best Practices
Custom themes built according to WordPress coding standards remain compatible with future WordPress updates and integrate seamlessly with plugins and functionality added later.
True Customization
Without the constraints of a commercial theme's architecture, we can implement exactly what your designs require—no workarounds, no limitations, no compromises.
Proven Partnership with Leading Agencies
Over the past decade, we've delivered hundreds of custom WordPress websites for agencies and design studios, including established firms like Gensler, Sage Growth, Olive AI, and Webb Mason.
Case Study: Long-Term Partnership with Gensler
Our partnership with Gensler, one of the world's leading architecture and design firms, exemplifies how white-label custom WordPress development supports agency success.
For projects such as Coyle & Company and New Hudson Facades, Gensler led the design and account management, while we handled all technical execution. We translated their sophisticated architectural designs into fast, scalable, and custom WordPress themes that continue to perform reliably years later.
This multi-project partnership demonstrates how agencies can confidently take on design-driven WordPress projects, knowing they have a reliable development partner who delivers pixel-perfect results under their brand.

Frequently Asked Questions About Custom WordPress Theme Development
Can you work with any design tool or file format?
Yes, FatLab can translate designs from any professional design tool into custom WordPress themes. We regularly work with Figma, Adobe XD, Photoshop (PSD), Sketch, InVision, Adobe Illustrator, and even detailed PDF specifications or annotated wireframes. Our developers are experienced in extracting design specifications from any format and implementing them pixel-perfectly in WordPress. If you can design it, we can build it as a custom WordPress theme.
How do you ensure designs are implemented pixel-perfectly?
Our developers use professional measurement and verification tools to ensure pixel-perfect accuracy between your design files and the final WordPress implementation. We check spacing, typography, colors, layout positioning, and responsive behavior against your original designs at every stage of development. Each element is measured and verified before we move to the next phase. We don't consider a section complete until it matches your designs exactly, and our unlimited revision guarantee, within scope, ensures that any discrepancies are corrected immediately.
What if designs change after development starts?
Minor design refinements and adjustments within the original project scope are included in our quality guarantee at no additional cost. Suppose you or your client requests more significant design changes that expand beyond the original scope. In that case, we will discuss these transparently with you and provide clear pricing for any additional work before proceeding. This protects both parties while ensuring you have flexibility to refine designs as needed.
Can you add custom functionality beyond what's in the original designs?
Absolutely. FatLab builds custom WordPress functionality, integrates third-party services, develops custom plugins, and implements any WordPress capabilities your project requires. Custom functionality—such as custom post types, advanced search features, member portals, API integrations, or unique interactive elements—should be discussed during initial project scoping to ensure they're properly included in timelines and pricing.
Do clients need technical knowledge to manage their WordPress site after launch?
No technical knowledge is required. We build intuitive content editing interfaces specifically designed for non-technical users, allowing your clients to confidently manage their WordPress websites without requiring coding skills or technical expertise. We provide comprehensive training, including video tutorials, written documentation, and live training sessions as needed. We also offer ongoing support packages for clients who want technical assistance available whenever needed.
What happens if something breaks after the website launches?
If issues arise from our custom development work, we fix them at no cost as part of our quality guarantee. We stand behind our work and provide warranty support on all custom code we write. If issues stem from other factors—such as third-party plugin conflicts, hosting environment problems, or modifications made by others—we can troubleshoot and resolve them as part of an ongoing support arrangement or quoted separately for one-time fixes.
Can FatLab handle WordPress websites at enterprise scale?
Yes, FatLab has extensive experience building and maintaining enterprise-level WordPress websites. We've delivered custom WordPress solutions for universities, professional associations, Fortune 500 companies, and organizations with complex requirements, high-traffic demands, and sophisticated functionality needs. Our portfolio includes WordPress multisite networks serving thousands of users, custom learning management systems for medical certification, and mission-critical websites that operate 24/7/365.
How do revisions and client feedback work in white label partnerships?
We provide staging environments where you and your clients can review work in progress at any time. You control how feedback flows—some agencies prefer that we communicate directly with their clients for technical discussions (with the agency involved). In contrast, others prefer all feedback to be filtered through the agency. Either approach works. We implement all requested changes within the defined project scope and don't limit the number of revision rounds. Our job is to deliver exactly what you and your client approved.
How long does custom WordPress theme development take?
Most custom WordPress theme projects are completed within 2-6 weeks from approved designs to launch-ready delivery. Simple brochure websites with 5-10 pages typically take 2-3 weeks to complete. Standard business sites with 10-20 pages and moderate custom functionality typically take 3-4 weeks. Complex websites with extensive custom functionality, multiple custom post types, third-party integrations, or e-commerce features typically take 4-6 weeks. The timeline depends on the project scope and complexity, which we define clearly during the initial project scoping.
What's included in your fixed project pricing?
Our fixed project pricing includes all development work within the defined scope, unlimited revisions and refinements within that scope, quality assurance testing across browsers and devices, responsive design implementation, basic SEO optimization, training and documentation, and launch support. Once we agree on project scope and price, that's what you pay—no hourly overages, no surprise costs, no charging for revisions. Additional functionality beyond the original scope is discussed and priced transparently before any work begins.
Do you sign NDAs to protect agency-client relationships?
Yes, FatLab signs non-disclosure agreements (NDAs) to protect your client relationships, proprietary information, and agency reputation. Your designs, client details, business processes, and all project information remain completely confidential. We understand that protecting agency-client relationships is paramount in white label partnerships, and we take those legal protections seriously.
Can you work with our existing WordPress hosting provider?
Yes, we can develop custom WordPress themes for deployment on any hosting environment. Whether your client uses WordPress-specific hosting, such as WP Engine or Kinsta, or shared hosting, VPS, or dedicated servers, we ensure that our custom themes work flawlessly in their environment. We can also advise on hosting requirements during project planning if you're unsure whether current hosting can support the planned website functionality.
