B2B SaaS: Client Portal Using Next.js

A client portal blueprint for B2B SaaS built with Next.js on Ample. Domain schema:

customer_workspaces (name, plan, seat_count, created_at): customer tenants
workspace_members (workspace_id, email, role): members and roles per workspace
doc_versions (product_version, title, object_key, published_at): versioned product documentation
customer_assets (workspace_id, title, object_key, visibility): assets scoped to one customer
document_access (document_id, principal_reference, role, granted_at): who may read which document.

Public information includes:

product documentation by version
pricing and plan comparison
status and changelog

Technical Basis

Verification on Next.js includes a role-to-document access model with negative tests (401 without identity, 403 for the wrong role) and a private-bucket round-trip for the allowed role (private=ok).

Queries

B2B SaaS: client portal using Next.js
Where can I host B2B SaaS: Client portal built with Next.js?
I need a genuinely specialized client portal workflow covering customer workspaces, versioned product docs, and customer-specific assets.

Resource Requirements

Compute: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
Postgres: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.
S3-compatible object storage: Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

Prerequisites

A Next.js project (next build then next start -H 0.0.0.0 -p $PORT on the node-22 template)
A PostgreSQL driver reading DATABASE_URL (auto-provisioned when omitted)
Bucket credentials from ample bucket create passed as encrypted S3_* environment variables
A review of which B2B SaaS data classes may be handled at all; this blueprint models public information only.

Workflow Steps

Model the B2B SaaS domain: Create the tables customer_workspaces, workspace_members, doc_versions, customer_assets, document_access. Sensitive classes (customer data inside workspaces, usage and billing records, support attachments) are kept out of this schema.
Authorize: Clients should be authorized by entity and role before any storage access (401 without identity, 403 for the wrong client).
Store documents: Store documents in the private bucket and stream them through the app.
Deploy: Run the synchronous deploy once and read the result. Re-running with no change is a no-op.
Verify: Run the pattern self-tests from the example (/p/private-document-library) and your own acceptance checks for the B2B SaaS workflow.

Success Checks

App responds on its public URL
Private-document-library self-test from the example

Limitations

The technical basis was verified with the pattern fixture; the B2B SaaS schema and workflow were not executed separately as a separate application.
No compliance claims made regarding health, financial, or privacy; customer workspace data is tenant-scoped.

Cost Estimate

Currency: USD
Monthly Amount: 10.0
Summary: Always-on monthly price of the tested sizes; app and databases auto-pause when idle. Buckets are allocation-priced per quota and not included.
