Product description

Multi-tenant SaaS platform on PHP 8 + SQLite with subscriptions, invoices and API — source code that works right after unzip.

This is not a code sample — it is the frame to launch your service the same evening: team signup, 3 plans, 14-day trial, auto-numbered invoices, kanban projects, REST API with tokens and rate limiting, HMAC-signed webhooks, audit log.

WHAT'S INSIDE

Multi-tenancy: every account sees only its own data — isolation covered by tests
Subscriptions: Free / Pro 990 RUB / Team 2990 RUB (edit one config file)
Trial and grace period: after expiry the account stays read-only for GRACE_DAYS — no data loss
Invoices: integer kopecks instead of float — zero rounding errors, renewals stack on the paid period
Team: invites, roles, owner protection, plan limits
Projects and tasks: kanban board, assignees, statuses
REST API v1: /api/v1/me, /api/v1/projects (GET/POST), /api/v1/projects/{id}/tasks — Bearer tokens, 60 req/min, plan feature-gate
Webhooks: project.created, task.done, invoice.paid, member.joined — HMAC-SHA256 signature, 3 delivery attempts
Security: bcrypt, CSRF tokens, HttpOnly sessions, parameterised SQL, escaped output

WHY NO PAYMENT GATEWAY OUT OF THE BOX

YooKassa/CloudPayments integration is ~5 lines on the gateway webhook side, but every seller has a different provider. The single integration point is Plan::subscribe() — it creates the invoice and extends the period. Step-by-step guide with code in docs/BILLING.md. That is why nothing will turn out to be a stub once you wire the real provider.

QUALITY

php tests/selftest.php — 64 automated checks: schema, tenant isolation, plan limits, kopecks billing, renewals, team, CSRF, webhook HMAC, API chain
Every PHP file passes the linter; the whole app was exercised with live HTTP scenarios (signup → project → upgrade → API → signed webhook delivery)
Gallery screenshots are the real running UI on a live server, not mockups
