White-label SaaS lets you sell software under your brand without building it from scratch. Agencies, resellers, and entrepreneurs use white-label products to enter markets faster and scale without large engineering teams. The decision to build custom white-label software or buy an existing platform affects your costs, timeline, differentiation, and long-term control.
This guide covers what white-label SaaS is, the business model, benefits, build custom vs buy existing, cost comparison, revenue models (per-seat, revenue share), technology requirements, go-to-market strategy, and examples.
What Is White-Label SaaS?
White-label SaaS is software that you license and rebrand as your own. The underlying product is built by another company; you provide the branding, marketing, support, and customer relationship. Your customers see your logo, your domain, and your support — not the original vendor's.
| Component | Vendor Provides | You Provide | |-----------|-----------------|-------------| | Product | Core software, updates, infrastructure | — | | Branding | White-label capability | Your logo, colors, domain | | Support | Technical support to you | Customer-facing support | | Sales | — | Your sales process | | Billing | May offer reseller billing | Or you bill directly | | Customization | Config options, sometimes custom dev | Feature requests, integration needs |
White-Label vs Reseller vs Private Label
| Term | Definition | |------|------------| | White-label | Rebrand existing product; minimal customization | | Reseller | Sell under vendor brand or co-branded; less rebranding | | Private label | Deeper customization; may include custom development | | OEM | Embed or bundle; often deeper technical integration |
In practice, "white-label" and "private label" are often used interchangeably. The key: you own the customer relationship and branding; the vendor owns the product.
White-Label Business Model
| Role | Description | Example | |------|-------------|---------| | Vendor | Builds white-label product | Platform that agencies license | | Reseller/Partner | Licenses, rebrands, sells | Agency selling CRM to clients | | End customer | Uses the software | Agency's client |
Revenue flow: End customer pays reseller → Reseller pays vendor (license fee) → Reseller keeps margin.
| Model | How It Works | |-------|--------------| | Markup | Reseller pays $X per seat; charges customer $X + margin | | Revenue share | Vendor takes % of reseller's revenue | | Flat license | Reseller pays fixed monthly/annual fee | | Usage-based | Reseller pays per API call, transaction, etc. |
Benefits of White-Label SaaS
| Benefit | Description | |---------|-------------| | Faster time to market | No 12–24 month build; launch in weeks | | Lower upfront cost | License vs build from scratch | | Proven product | Vendor has solved core problems | | Focus on sales and support | Less engineering, more go-to-market | | Scalability | Vendor handles infrastructure and updates | | Access to features | Roadmap and updates from vendor | | Reduced risk | Validate demand before building |
| Drawback | Mitigation | |----------|------------| | Less differentiation | Add services, integrations, vertical focus | | Vendor dependency | Contract terms, SLAs, exit strategy | | Limited customization | Negotiate custom dev or build extensions | | Margin pressure | Volume pricing, value-added services | | Brand alignment | Choose vendor whose product fits your brand |
Build Custom vs Buy Existing
| Factor | Build Custom | Buy White-Label | |--------|--------------|-----------------| | Upfront cost | $100,000–$500,000+ | $0–$50,000 (setup, integration) | | Time to market | 6–18+ months | 1–3 months | | Customization | Full control | Config + optional custom dev | | Differentiation | Complete | Depends on add-ons | | Ongoing dev cost | Engineering team | License fees | | Support burden | You own it | Vendor supports product; you support customers | | Roadmap control | Full | Vendor-driven | | Exit flexibility | Sell or sunset | Re-platform or renew |
When to Build Custom White-Label
| Scenario | Why Build | |----------|-----------| | No suitable product exists | Unique vertical, specific workflows | | Need full control | Roadmap, data, compliance | | Large addressable market | ROI justifies build cost | | Strategic asset | Product is core to company value | | Compliance requirements | Vendor products don't meet them | | High margin potential | Willing to invest in differentiation |
When to Buy White-Label
| Scenario | Why Buy | |----------|---------| | Proven product category | CRM, email, project management, etc. | | Fast validation | Test market before heavy investment | | Limited technical resources | No engineering team | | Commodity functionality | Little differentiation in core features | | Capital constraints | Can't fund full build | | Vendor has strong roadmap | Their investment exceeds yours |

Cost Comparison
| Phase | Build Custom | Buy White-Label | |-------|--------------|-----------------| | Year 1 | $150,000–$400,000 | $20,000–$80,000 (license + setup) | | Year 2 | $80,000–$150,000 (maintenance) | $30,000–$100,000 (license + growth) | | Year 3 | $80,000–$150,000 | $40,000–$120,000 | | 3-year total | $310,000–$700,000 | $90,000–$300,000 |
Build costs vary by scope. White-label costs vary by pricing model (per-seat, % revenue) and volume. At low volume, white-label is usually cheaper; at high volume, custom build can yield better unit economics.
| Volume | Build Often Wins | White-Label Often Wins | |--------|------------------|------------------------| | < 100 customers | — | Yes | | 100–500 | Maybe (if high ACV) | Yes | | 500–2,000 | Depends on margin | Either | | 2,000+ | Yes (if margin supports it) | Maybe (license fees add up) |

Revenue Models for White-Label
| Model | Pros | Cons | |-------|------|-----| | Per-seat/month | Predictable; scales with usage | Caps margin if vendor fee is high | | Revenue share (%) | Aligns vendor with your success | Less predictable; can be costly at scale | | Flat subscription | Simple; good for small teams | May not scale with your growth | | Setup + transaction fee | Low barrier; pay as you earn | Can add up with volume | | Tiered pricing | Volume discounts | More complex to manage |
Example (per-seat): Vendor charges $20/seat; you charge $50/seat → $30 margin per seat. At 200 seats, $6,000/month margin.
Example (revenue share): Vendor takes 20%; you charge $50/seat → $40 to you, $10 to vendor per seat.
Technology Requirements
Whether you build or buy, you need:
| Requirement | Build | Buy | |--------------|------|-----| | Custom domain | You configure | Vendor provides CNAME/subdomain | | Logo and branding | You design | Vendor has theme/white-label settings | | SSO/SAML | You implement or use IdP | Vendor may offer | | API access | You build | Vendor may provide | | Integrations | You build or use vendor ecosystem | Check vendor marketplace | | Data residency | You choose infra | Vendor policy | | Compliance (SOC 2, GDPR) | You obtain | Vendor should have | | Support tools | You set up | Vendor may offer help desk integration |
Due diligence: Evaluate vendor security, compliance, uptime, support SLAs, and contract terms (pricing, lock-in, data ownership).
Go-to-Market Strategy
| Element | Action | |---------|--------| | Target segment | Vertical (e.g., agencies, healthcare) or horizontal | | Positioning | How you're different (support, integrations, vertical expertise) | | Pricing | Match market; ensure margin after vendor cost | | Channels | Direct sales, partnerships, inbound | | Onboarding | Smooth setup; minimize time to value | | Support | Define L1/L2; vendor handles L3 | | Success metrics | Adoption, retention, NPS |
Differentiation: White-label products can look similar. Differentiate with:
- Vertical expertise (e.g., agency-specific workflows)
- Integrations (connect to tools your customers use)
- Service wrapping (onboarding, training, consulting)
- Localization or compliance for your market

Vendor Evaluation Checklist
When evaluating white-label vendors, assess:
| Criterion | Questions to Ask | |-----------|------------------| | White-label depth | Custom domain? Logo? Colors? Login page? | | Pricing model | Per-seat, rev share, flat? Volume discounts? | | Contract terms | Minimum commitment? Exit clause? Price escalation? | | Data ownership | Your data vs vendor? Export on termination? | | Compliance | SOC 2? GDPR? Industry-specific (HIPAA, etc.)? | | Uptime | SLA? Credit for downtime? | | Support | Response time? Included or extra? | | Roadmap | Influence? Visibility? | | Integration | API? Webhooks? Zapier? | | Customization | Config only? Custom dev available? |
Shortlist 2–3 vendors and run a pilot or proof of concept before committing.
Common White-Label Pitfalls
| Pitfall | How to Avoid | |---------|--------------| | Vendor lock-in | Understand exit costs; data portability | | Hidden fees | Read fine print; usage-based caps | | Brand misalignment | Demo with your branding before signing | | Support gap | Clarify L1/L2/L3; escalation path | | Roadmap mismatch | Align on priority features | | Underestimating setup | Budget for integration, training, launch | | Margin erosion | Model at scale; negotiate volume pricing |
Building a White-Label Reseller Program
If you're the vendor building a white-label product, consider how you'll enable resellers:
| Component | Description | |-----------|-------------| | Partner onboarding | Self-serve signup or sales-assisted; clear documentation | | Branding tools | Theme editor, logo upload, custom domain setup | | Billing options | Reseller bills customer; or you bill reseller; or usage-based | | Support model | Reseller handles L1; you provide L2/L3 and escalation | | Partner portal | Dashboard for usage, billing, support tickets | | Co-marketing | Lead sharing, case studies, co-branded materials | | Revenue share or margin | Clear, predictable pricing that lets resellers profit |
A strong partner program can drive most of your growth; design it with reseller success in mind.
Summary
- White-label SaaS: License and rebrand a vendor's product; you own customer relationship.
- Benefits: Faster launch, lower upfront cost, proven product.
- Build vs buy: Build when no product fits or you need full control; buy when a good fit exists and speed matters.
- Costs: Build $150k–$400k Year 1; white-label $20k–$80k typically.
- Revenue models: Per-seat, revenue share, flat fee — choose based on margin and scalability.
- GTM: Differentiate with vertical focus, integrations, and service wrapping.
The right choice depends on your market, resources, and timeline. Validate demand with white-label first; build when scale and differentiation justify the investment.
