Digital agencies: client portal using Next.js

Summary

A client portal blueprint for digital agencies built with Next.js on Ample. Domain schema: client_entities (name, brand, primary_contact_role): client brands; engagements (client_entity_id, campaign_or_project, period_start, period_end, status): retainers and projects; approval_rounds (engagement_id, round_no, asset_object_key, status, decided_at): creative approval rounds; deliverables (engagement_id, title, object_key, version): final assets delivered; document_access (document_id, principal_reference, role, granted_at): who may read which document. Public information: services and case studies, team, contact. Kept out of scope until handling is reviewed: unreleased creative and campaign plans, client analytics exports, brand credentials. Unreleased creative is confidential; brand platform credentials never belong in these flows. Technical basis verified on Next.js: 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).

Infrastructure requirements

Prerequisites

Exact tested configuration

Steps

  1. Model the digital agencies domain. Create the tables client_entities, engagements, approval_rounds, deliverables, document_access. Client brands lives in client_entities; keep the sensitive classes (unreleased creative and campaign plans, client analytics exports, brand credentials) out of this schema.

  2. Workflow step 1. Model client entities and engagement periods; every document belongs to one engagement

  3. Workflow step 2. Authorize by client entity and role before any storage access (401 without identity, 403 for the wrong client)

  4. Workflow step 3. Store documents in the private bucket and stream them through the app

  5. Workflow step 4. Deploy and verify the negative authorization tests and an authorized download

  6. Deploy. Run the synchronous deploy once and read the result. Re-running with no change is a no-op.

    ample deploy . --name <app-name> --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...
    
  7. Verify. Run the pattern self-test(s) from the example (/p/private-document-library) and your own acceptance checks for the digital agencies workflow.

Limitations

Cost estimate

Estimated 10.00 USD per month (size prices from pricing.toml at build revision a1b8c38919e59cd035ebabaced73cf84ece24371).

Always-on monthly price of the tested sizes; apps and databases auto-pause when idle. Buckets are allocation-priced per quota and not included.
