Complete invoicing system built into NextCRM — create, issue, pay, duplicate, and cancel invoices with multi-currency support, tax rates, and PDF generation.

• Invoice types — Invoice, Credit Note, Proforma, and Receipt
• Line items — per-line quantity, unit price, discount %, and tax rate with automatic totals calculation
• Tax engine — configurable tax rates (VAT, GST, etc.) with per-line tax breakdown and VAT summary buckets
• Invoice series — auto-numbered sequences with configurable prefix/suffix (e.g. INV-2026-0001)
• Multi-currency — admin-managed currency list with locale-aware formatting via next-intl
• Status lifecycle — DRAFT → ISSUED → PAID / PARTIALLY_PAID / CANCELLED with permission guards (only drafts are editable)
• Payments — record partial/full payments, auto-computed balance due, payment history on detail page
• Duplicate & cancel — one-click invoice duplication; cancellation with audit trail
• Email delivery — send invoices to account email via Resend with React Email template
• PDF export — server-side PDF generation at /api/invoices/[id]/pdf
• Activity log — every status change and edit is recorded with actor and timestamp
• Admin settings — manage tax rates, invoice series, currencies, and default settings from /admin/invoices
• i18n — full English and Czech translations
• Server actions — create/update operations use Next.js server actions with Zod validation (no API route middleman)

All 5 CRM entity detail pages (Accounts, Contacts, Leads, Opportunities, Contracts) now have an Activities tab with a live paginated feed of interactions:

• Activity types — Notes, Calls, Emails, Meetings, Tasks
• Create / edit / delete — inline Sheet form on every CRM entity detail page
• Paginated feed — compound cursor pagination with createdAt + id for stable ordering
• Linked records — activities attach to multiple entities via crm_ActivityLinks (e.g. a call can reference both a Contact and an Opportunity)
• Real-time revalidation — server actions revalidate the correct path after every mutation

Every CRM entity (Accounts, Contacts, Leads, Opportunities, Contracts) now tracks its full change history:

• History tab — per-entity timeline of all field changes, shown on every detail page with AuditTimeline + AuditEntry components
• Soft delete — records are never hard-deleted; deletedAt column preserves data while hiding it from normal queries
• Admin audit log — /admin/audit-log shows a global filterable table of every change across all entities, with restore support for soft-deleted records
• Diff engine — diffObjects utility computes before/after diffs and stores structured JSON in the audit record

Background target enrichment (queued, bulk and MCP) now runs inside an E2B cloud sandbox — a full Linux environment with a real browser (Chrome). Contact enrichment and interactive target enrichment still use Firecrawl + OpenAI:

• Real-browser research — the agent navigates JS-heavy sites, LinkedIn public profiles, and paginated results that a simple API call cannot reach
• LLM tool-use loop — Claude Sonnet 4.6 drives the research with tools: browser_open, browser_snapshot, browser_click, browser_extract, web_search
• C-level contact discovery — given only a company name, the agent finds all discoverable C-level contacts and creates crm_Target_Contact records automatically
• Context-aware strategy — agent skips research it doesn't need (e.g. already has a website → skips domain discovery)
• Confidence scoring — fields below 0.6 confidence are discarded; only empty target fields are overwritten
• 5-minute timeout per target — partial results are applied even if the agent times out
• Fan-out — after company enrichment, each discovered contact is enriched independently via a separate Inngest job

Enrichment API keys (OpenAI, Firecrawl, Anthropic) are resolved through a 3-tier priority system, so enrichment works without those keys in .env. Other AI features (record embeddings, document enrichment) read OPENAI_API_KEY from the environment only, and E2B needs E2B_API_KEY in the environment:

ENV variable  →  Admin system-wide  →  User profile
(highest)                              (lowest)

• Admin panel (/admin/llm-keys) — set system-wide keys for OpenAI, Firecrawl, Anthropic, and Groq. Keys are encrypted at rest (AES-256-GCM).
• Profile settings (/profile?tab=llms) — users configure their own keys as a fallback.
• Graceful degradation — enrichment buttons show an informative dialog when no key is available at any tier.

Migration note: The old openAi_keys table is replaced by the new ApiKeys table. Run pnpm prisma migrate deploy to apply the migration.

NextCRM now ships with a built-in Model Context Protocol server, letting AI agents (Claude, Cursor, custom agents) read and write CRM data directly.

105 tools across 16 modules:

Authentication: Generate Bearer tokens (nxtc__...) from your profile page. Tokens are SHA-256 hashed — the raw value is shown only once and never stored.

Connect your MCP client (streamable HTTP — recommended):

{
  "mcpServers": {
    "nextcrm": {
      "type": "http",
      "url": "https://your-nextcrm.com/api/mcp/mcp",
      "headers": { "Authorization": "Bearer nxtc__your_token_here" }
    }
  }
}

The server supports both MCP transports defined by mcp-handler:

• Streamable HTTP at /api/mcp/mcp — single POST endpoint, current MCP spec default
• SSE (legacy) at /api/mcp/sse — GET stream paired with POSTs to /api/mcp/message (client auto-discovers the message endpoint)

Claude Code Skill: Download the SKILL.md from your Developer profile tab for a ready-to-use Claude Code skill with full tool documentation.

CRM records (Accounts, Contacts, Leads, Opportunities) are automatically embedded using OpenAI text-embedding-3-small via Inngest background jobs.

• Unified search — combines keyword (full-text) + semantic (pgvector cosine similarity) results in a single grouped UI
• Find Similar — every CRM detail page has a "Find Similar" button that surfaces semantically related records across the same module
• Backfill — Inngest function to embed all existing records on demand
• Auto-embed — new and updated records are embedded automatically

Powered by pgvector (PostgreSQL extension) with HNSW indexes for fast approximate nearest-neighbor search.

New Targets module for managing sales targets and target lists — full CRUD, detail view, list management, and MCP tools included.

Global search across all CRM entities from a single search bar — grouped results by entity type, loading skeleton, collapsible sections, and combined keyword + semantic scoring.

We use resend.com + react.email as primary email sender and email templates.

NextCRM supports Mailtrap as an alternative email provider to Resend, for both production sending and safe dev/staging testing through a single API.

Sending emails (production):

1. Sign up at mailtrap.io and create a Sending domain.
2. Copy your API token.
3. Add it to your .env.local: MAILTRAP_API_KEY=

Testing emails (dev/staging, optional):

Use a Mailtrap Sandbox inbox instead of a production domain during development, so test emails (OTP, invoices, notifications) never reach real inboxes.

We use Tremor charts as a tool for creating charts in NextCRM

The fastest way to run NextCRM is with Docker Compose. The provided docker-compose.yml bundles everything you need: the app, PostgreSQL (with pgvector), MinIO for file storage, and Inngest for background jobs. No manual setup of databases, buckets, or migrations — it all happens automatically on first start.

git clone https://github.com/pdovhomilja/nextcrm-app.git
cd nextcrm-app
cp .env.docker .env
nano .env                # set ADMIN_EMAIL to a real email you own
docker compose up -d

Windows: cp and nano are not available on Windows. Use Copy-Item (PowerShell) or copy (Command Prompt) to copy the file, and edit it with notepad:

Copy-Item .env.docker .env
notepad .env           # set ADMIN_EMAIL to a real email you own

Open http://localhost:3000 — the app is ready, the schema is migrated, and the seeded admin user matches the ADMIN_EMAIL you set.

The app is published on port 3000. MinIO's S3 port is published on 127.0.0.1:9000 because browsers upload and download files directly from MinIO; on a server, give MinIO its own domain and set MINIO_PUBLIC_URL to it. Postgres and Inngest stay on the internal Docker network. Uncomment the relevant ports: blocks in docker-compose.yml if you need direct access (e.g. for psql or the MinIO console).

You never edit Dockerfile or docker-compose.yml to add your secrets. Instead, create a .env file in the project root — Docker Compose reads it automatically and injects the values into the container.

cp .env.docker .env
nano .env       # set ADMIN_EMAIL, internal service passwords, and any optional API keys
docker compose up -d

Windows (PowerShell):

Copy-Item .env.docker .env
notepad .env    # set ADMIN_EMAIL, internal service passwords, and any optional API keys
docker compose up -d

On a server, also set the two public URLs:

APP_URL=https://crm.example.com          # what people open; used for auth and links
MINIO_PUBLIC_URL=https://files.example.com  # what browsers use to reach MinIO

Secrets. BETTER_AUTH_SECRET, EMAIL_ENCRYPTION_KEY, INNGEST_SIGNING_KEY and INNGEST_EVENT_KEY are generated on first start and stored in the app_data volume, so they survive restarts and upgrades. You can set them in .env instead; a value in the environment always wins. Never change them once set: a new BETTER_AUTH_SECRET logs everyone out, a new EMAIL_ENCRYPTION_KEY makes stored mailbox passwords and API keys unreadable.

The .env.docker file lists every supported variable with comments. Beyond the internal service passwords, you only need to add values for optional external integrations you want to enable. API keys left empty can also be entered in the admin panel; an environment value always wins over the admin panel:

# Example .env
OPENAI_API_KEY=sk-your-real-key       # enables AI features
GOOGLE_ID=...apps.googleusercontent.com  # enables Google OAuth
GOOGLE_SECRET=GOCSPX-...
RESEND_API_KEY=re_...                 # enables transactional email
EMAIL_FROM=noreply@yourdomain.com     # verified Resend sender for login codes
FIRECRAWL_API_KEY=fc-...              # enables contact enrichment

.env is in .gitignore, so your secrets never get committed.

Data persists across restarts in four named volumes:

• postgres_data — your database
• minio_data — uploaded files
• app_data — generated secrets (/app/data/secrets); back it up with the database
• inngest_data — background job state (queued runs, schedules)

docker compose down        # stops services, keeps data
docker compose down -v     # stops services AND wipes all data

git pull
docker compose up -d --build

The entrypoint runs prisma migrate deploy on every start, so new schema changes are applied automatically. The seed only runs on first install (when no users exist), so your data is safe across upgrades.

This setup works with self-hosting platforms:

• Coolify — point it at this repo, choose "Docker Compose" build pack with /docker-compose-coolify.yml, set your env vars in Coolify's UI (required ones are listed at the top of that file). Assign your domain to the app service (port 3000) and a second domain to minio (port 9000), then set APP_URL and MINIO_PUBLIC_URL to them.
• Portainer / Dockge — paste docker-compose.yml into a stack, add env vars in the UI

In all cases, env vars set through the platform UI override the defaults in docker-compose.yml the same way a .env file does locally.

After first start, the seeded admin account uses whatever you set in ADMIN_EMAIL. Since login is passwordless Email OTP, there are two paths:

With email provider configured (recommended)

Set RESEND_API_KEY and EMAIL_FROM in .env, then enter your ADMIN_EMAIL on the sign-in page and check your inbox for the OTP.

Without email provider (first-run testing)

Read the OTP directly from the database:

docker compose exec postgres psql -U nextcrm -d nextcrm \
  -c 'SELECT identifier, value, "expiresAt" FROM verification ORDER BY "createdAt" DESC LIMIT 1;'

(identifier ends with the email; value is the OTP code followed by : and the attempt count, e.g. 606331:0.)

Use that OTP on the sign-in page. After login, configure an email provider from the Admin panel so future logins work normally.
