Before You Start (Prerequisites)

A few hours of preparation can save weeks of rework. Clarify your goals, choose the right tenancy model, and set your delivery rails.

• Define problem and audience
  • Who is the tenant? Company, franchise, or department?
  • What outcomes must v1 prove (measurable and time-bound)?
  • Which integrations are must-have vs nice-to-have?
• Decide tenancy model
  • Single-tenant: database per customer; strongest isolation; more ops overhead
  • Multi-tenant: shared app + tenant scoping; fast to ship; efficient to operate
  • Hybrid paths exist—start shared, move key accounts to isolated databases later
• Choose baseline stack
  • Laravel LTS, PHP 8.2+, MySQL or PostgreSQL, Redis for cache/queues
  • Object storage (S3-compatible), job queues, scheduler, and mail
  • Testing (Pest/PHPUnit), static analysis (Larastan), code style (Pint)
• Security posture
  • 2FA, RBAC, audit logs, secrets management, SSO readiness
  • Secure headers, rate limiting, IP allowlists for admin endpoints
• Delivery approach
  • Trunk-based development, PR reviews, automated tests, feature flags
  • CI/CD from day one; no manual deployments to production

How to Build SaaS Application Laravel: Step-by-Step Process

Here’s the exact sequence we use on real projects at Codepaper—whether it’s an MVP for a startup or an enterprise rollout.

1) Initialize your Laravel SaaS workspace

• Bootstrap the project
  • Create the repo; set up .editorconfig, linting, and Git hooks
  • Configure .env per environment; wire DB, cache, queue, mail
  • Establish app/Domain for bounded contexts (e.g., Billing, Tenancy)
• Core packages
  • Auth: Breeze/Fortify; API tokens: Sanctum
  • Queues: Redis + Horizon; Mail: first-party drivers
  • Validation and form requests; resource transformers
• Documentation and standards
  • Decision records in docs/
  • Larastan and Pint in CI for consistent code quality

2) Design tenancy and data boundaries

• Pick your model
  • Shared DB with tenant_id scoping for speed and simplicity
  • Schema-per-tenant or DB-per-tenant for strict isolation or premium accounts
• Routing and provisioning
  • Subdomain (acme.yourapp.com) or custom domain (acme.com)
  • Automate tenant creation, seeding, SSL, DNS, and domain verification
• Cache and queues
  • Namespace per tenant to prevent cross-tenant leakage
  • Tag logs and metrics with tenant_id for observability

3) Authentication, roles, and onboarding

• Auth flows
  • Email+password, OAuth SSO, or SAML depending on audience
  • 2FA, password policies, device/session management
• Role-based access control (RBAC)
  • Policies + gates; Admin, Manager, Member per tenant
  • Invite flows and user provisioning scoped to tenants
• First-run experience
  • Guided setup wizard; sample data; contextual tips per screen
  • Progressive profiling to capture key org details without friction

4) Subscriptions and billing

• Cashier integration
  • Plans, trials, metered usage, prorations, and invoices
  • Handle webhooks (invoice paid, past_due, subscription canceled)
• Entitlements
  • Feature flags per plan; rate limits and quotas by tier
  • Grace periods and downgrade safeguards to prevent data loss
• Compliance considerations
  • Tax rules differ by region; ensure correct tax IDs and receipts
  • Keep personal and payment data minimal and well-protected

5) Build core domain features

• Start narrow, win fast
  • Ship one workflow that proves undeniable value in days
  • Instrument it for usage, latency, and conversion
• Event-driven patterns
  • Dispatch domain events; queued listeners handle heavy work
  • Keep controllers skinny; push logic into services and actions
• Storage and search
  • Use object storage for media; scoped search indices per tenant
  • Background jobs generate thumbnails, exports, and reports

6) APIs, webhooks, and integrations

• REST + tokens
  • Sanctum for first-party SPAs and token-based access
  • Rate limits aligned with subscription plans
• Webhooks
  • Use signed payloads, exponential backoff with jitter, dead-letter queues
  • Provide a replay endpoint and clear delivery statuses
• 3rd-party connectors
  • Isolate integration code; circuit-breaker and retry patterns
  • Store minimal tokens; rotate secrets regularly

7) Security-by-default

• App-level protections
  • CSRF, XSS, and SQL injection defenses; validate and sanitize inputs
  • Encrypt sensitive fields; rotate keys; secure cookie settings
• Tenant isolation
  • Middleware enforces tenant context; deny on mismatch
  • Separate caches/queues per tenant; verify in tests
• Operational security
  • Least privilege IAM; MFA on consoles; tamper-evident audit logs
  • Automated dependency and container scanning in CI

8) Observability: logs, metrics, and tracing

• Structured logging
  • Include tenant_id, request_id, and user_id in each log
  • Standardize log levels; alert on error spikes
• Metrics that matter
  • Signups, activation, churn signals, job failures, latency per tenant
  • Release health: error rate, p95 latency, and rollback frequency
• Distributed tracing
  • Trace across web, workers, and external APIs for root-cause speed

9) CI/CD and environments

• Pipelines
  • Run unit/integration tests, linters, security scans, and DB migrations
  • Blue/green or canary releases with automated rollback hooks
• Environment strategy
  • Dev → Staging → Production with anonymized fixtures
  • Preview environments per feature branch for rapid product feedback

10) Deploy, launch, and iterate

• Production hardening
  • WAF, secure headers, rate limits, and backup verification
  • Queue concurrency tuned by workload and plan tiers
• Launch checklist
  • Domain setup, SSL, sender reputation (SPF/DKIM/DMARC), and status page
  • Runbooks for incidents; define clear SLOs and on-call rotations
• Continuous improvement
  • Instrument everything; prioritize changes by actual usage
  • Close the feedback loop with in-app surveys and NPS

Comparison: Tenancy Models and When to Use Them

Model	Pros	Cons	Use When
Shared DB (row-level)	Fastest to ship; efficient to run; simpler migrations	Requires careful scoping; potential noisy neighbor risk	Early-stage SaaS with many small tenants
Schema-per-tenant	Good isolation; per-tenant migrations possible	Operational overhead; more complex tooling	Mid-market tenants with customization needs
DB-per-tenant	Strong isolation and performance guarantees	Most complex to manage at scale	Enterprise or regulated customers

Troubleshooting (Real-World Fixes)

• Cross-tenant data exposure
  • Audit every query for tenant scope; enforce in base repositories
  • Namespace caches/queues; invalidate on tenant switch
• Webhook retries flooding your system
  • Use idempotency keys; exponential backoff with jitter; dead-letter queues
  • Replay endpoint with clear statuses
• Migrations failing per tenant
  • Version and order migrations; add health checks and auto-heal scripts
  • Test upgrade/downgrade paths in staging with realistic data
• Slow background jobs
  • Shard queues by job type; scale workers vertically/horizontally
  • Profile jobs and optimize N+1 queries
• Email deliverability pain
  • Warm IPs; configure SPF/DKIM/DMARC; monitor bounces/complaints
  • Use a dedicated subdomain for transactional mail

Advanced Tips (Optional)

• Feature flags
  • Roll out features by tenant, role, or cohort; kill switches for safety
• AI automation add-ons
  • Automate back-office steps (extractions, summarization) with review queues
  • Use guardrails and audits; log prompts/responses where appropriate
• Data analytics
  • Embedded dashboards per tenant; anonymize PII as needed
  • Track activation and retention cohorts to guide roadmap
• Zero-downtime releases
  • Blue/green or canary; migrations backward-compatible for one release
  • Feature toggles to decouple deploy from release

FAQ

• Is Laravel a good choice for SaaS?
  Yes. Laravel’s first-party packages, queues, caching, and ecosystem make it ideal for multi-tenant apps, subscriptions, and APIs. It’s productive for small teams and robust enough for enterprises.
• Should I start with single-tenant or multi-tenant?
  Most teams start multi-tenant for speed and operating efficiency. Move premium or regulated tenants to DB-per-tenant when isolation or custom SLAs require it.
• How do I secure tenant data?
  Enforce tenant context in middleware, scope all queries, separate caches/queues, and add audit logs. Encrypt sensitive fields and rotate secrets regularly.
• What about billing and taxes?
  Use Cashier for subscriptions and webhooks. Align plan entitlements with feature flags. Follow a tax advisor’s guidance for region-specific rules and record-keeping.
• When should I add mobile apps?
  Add mobile when users need on-the-go workflows. A shared API with role-aware endpoints keeps iOS/Android aligned with your web app.
