1. Big Picture¶

Launching Forma3D.Connect as a SaaS requires work across four domains — product, business operations, legal/compliance, and infrastructure — all of which must be ready before the first paying tenant goes live.

What you listed vs. what you're missing¶

2. Tenant Lifecycle¶

Every tenant passes through a defined lifecycle. Each state transition has business rules, technical actions, and communication requirements.

Lifecycle actions matrix¶

3. Onboarding¶

Onboarding is the highest-leverage moment in the customer journey. The goal is to reach the "aha moment" — seeing the first Shopify order flow through to a SimplyPrint print job — as fast as possible.

3.1 Self-service onboarding wizard¶

3.2 Onboarding checklist (persistent)¶

After the wizard, show a persistent checklist on the dashboard until all items are done:

3.3 Time-to-value target¶

4. Pricing & Packaging¶

4.1 Tier structure¶

Based on the market analysis recommendation with added detail on feature gating:

4.2 Billing periods¶

4.3 Free trial¶

4.4 Overage handling¶

4.5 Feature gating — server-side enforcement¶

Feature limits must be enforced server-side, not just hidden in the UI:

interface TenantLimits {
  maxOrdersPerMonth: number;
  maxPrinters: number;
  maxUsers: number;
  maxShopifyShops: number;
  hasApiAccess: boolean;
  hasAnalytics: boolean;
  hasActivityLogs: boolean;
  hasPushNotifications: boolean;
  hasCsvExport: boolean;
  supportSlaHours: number;
}

5. Billing — Stripe Integration¶

5.1 Stripe object model¶

5.2 Stripe webhook events to handle¶

5.3 Stripe integration architecture¶

5.4 Implementation approach¶

Use Stripe Checkout for initial subscription and Stripe Customer Portal for self-service management. This minimizes custom payment UI development and ensures PCI compliance.

6. Invoicing¶

6.1 Invoice requirements (EU-compliant)¶

Every invoice must include:

6.2 Belgian e-invoicing mandate (January 1, 2026)¶

Belgium mandates structured e-invoicing for B2B transactions from January 1, 2026. This means:

• B2B invoices must be issued in Peppol BIS 3.0 format
• Transmission via the Peppol network
• PDF invoices are no longer sufficient for Belgian B2B customers
• Stripe does not natively support Peppol; a Peppol Access Point integration is needed (e.g., Billit, Codabox, Digiteal)

6.3 Invoice access in dashboard¶

Tenants should be able to:

• View invoice history (fetched from Stripe API)
• Download individual invoices as PDF
• Access hosted invoice pages (Stripe-hosted)
• Update billing information (redirect to Stripe Customer Portal)

7. Tax Compliance — EU VAT¶

7.1 VAT rules for B2B SaaS¶

7.2 VAT implementation requirements¶

7.3 Stripe Tax¶

Stripe Tax automates VAT calculation and can be enabled per product/price. It handles:

• Automatic tax rate determination based on customer location
• Reverse charge detection for B2B EU cross-border
• Tax reporting exports for OSS filing
• Digital services classification

Recommendation: Use Stripe Tax from day one to avoid building a manual VAT rate table.

8. Dunning & Failed Payment Recovery¶

5–15% of recurring charges fail. Involuntary churn (failed payments) accounts for 20–40% of all subscription cancellations.

8.1 Recovery strategy¶

8.2 Stripe dunning configuration¶

9. Offboarding & Cancellation¶

9.1 Cancellation policy¶

Rationale for no prorated refunds on yearly plans:

• Yearly discount (17%) already represents a significant concession
• Predictable revenue enables better planning
• Industry standard for B2B SaaS (Shopify, HubSpot, Slack follow this model)
• Terms of Service must clearly state this policy
• Consider goodwill exceptions for enterprise customers (case-by-case)

9.2 Cancellation flow¶

9.3 Data after cancellation¶

10. GDPR & Data Protection¶

10.1 GDPR obligations for a multi-tenant SaaS¶

Forma3D.Connect acts as a Data Processor for tenant customer data (Shopify orders, addresses) and as a Data Controller for tenant account data (login, billing).

10.2 GDPR compliance checklist¶

10.3 Data retention schedule¶

11. EU Data Act — Data Portability¶

The EU Data Act (effective September 12, 2025) imposes obligations on SaaS providers that go beyond GDPR:

11.1 Key requirements¶

11.2 Data export scope¶

What must be exportable by a tenant:

12. Legal Framework¶

12.1 Required legal documents¶

12.2 Terms of Service — key clauses¶

12.3 Intellectual property protection¶

13. Security¶

13.1 Authentication hardening¶

13.2 Rate limiting¶

13.3 Security checklist¶

14. Multi-Lingual & Internationalization¶

14.1 Language support plan¶

14.2 What needs translation¶

14.3 Internationalization beyond translation¶

14.4 Implementation architecture¶

15. Email & Notifications¶

15.1 Email types¶

15.2 Onboarding drip sequence¶

Behavior-driven: Skip emails for steps already completed. If the tenant completes onboarding on day 1, switch to a "tips & tricks" sequence instead.

15.3 Email infrastructure¶

16. Analytics & Metrics¶

16.1 Business metrics to track¶

16.2 Product analytics¶

16.3 Internal dashboard¶

Build an internal (super-admin only) dashboard with:

• Total tenants by status (trial, active, past due, cancelled)
• MRR trend chart
• Churn waterfall
• Trial conversion funnel
• Top tenants by order volume
• System health overview

17. Customer Support & Success¶

17.1 Support channels¶

17.2 Knowledge base structure¶

17.3 Support metrics¶

18. Operational Readiness¶

18.1 Status page¶

A public status page is essential for SaaS credibility:

18.2 Uptime SLA¶

18.3 Monitoring stack¶

18.4 Backup & disaster recovery¶

19. Feature Flags & Gradual Rollout¶

19.1 Use cases¶

19.2 Implementation options¶

Recommendation: Start with database-backed feature flags per tenant (stored in the Tenant model). This integrates naturally with multi-tenancy and requires no external service. Migrate to a dedicated system (PostHog) when A/B testing becomes relevant.

20. Domain Architecture Overview¶

How all the SaaS concerns map to the existing Forma3D.Connect architecture:

21. Implementation Priority¶

Organized by what blocks the first paying customer vs. what can come later.

Phase 0 — Prerequisites (before any SaaS work)¶

Phase 1 — Minimum Viable SaaS (blocks first paying customer)¶

Phase 1 total estimate: 78–124 hours

Phase 2 — Launch Quality (needed for public launch)¶

Phase 2 total estimate: 56–92 hours

Phase 3 — Growth (post-launch improvements)¶

Phase 3 total estimate: 52–84 hours
