Open-source ERP + Qwik storefront · MIT
Your ERP and your storefront. One source of truth.
Fincas is a Django back office for quotes, orders, invoicing, a double-entry ledger, inventory and CRM, and a fast Qwik storefront that sells from the same data, live.
pip install fincas
Headless storefront, included
A Qwik storefront that runs on your ERP.
Most shops run an ERP and a storefront as two systems and spend their days keeping them in step. Fincas ships both, in one repository, and the store asks the ERP for everything.
One source of truth
The storefront has no catalog of its own. Products, variants, prices with quantity breaks, stock and SEO text come from the ERP on every request. No feed, no sync job, no second database.
Checkout lands in the back office
A guest checkout becomes a real sales order with an ERP order number, waiting in the order list for your staff.
Accounts on the same records
Signed-in customers see their profile and orders through the customer portal API, from the records your team works with.
Nothing secret in the browser
No API key ships to the client. Visitors get a short-lived, least-privilege token that can read the catalog and place a guest order, and nothing else.
Fast by design
Qwik resumes instead of hydrating, so pages ship almost no JavaScript up front, however big the catalog gets.
75 themes, switched live
Reskin the whole store at runtime, start from landing-page templates, and keep Playwright journeys with axe accessibility checks in CI.
Live demo
Click around. Break things. It resets every night.
Two public demos run the current release on sample data: the back office your team would use, and the storefront your customers would see.
Storefront
Browse the catalog, switch between 75 themes, open the landing-page templates and go through checkout.
Open shop.demo.fincas.devDemo data is made up and is restored every night, so anything you change disappears by morning. Outgoing email is switched off.
What's in it
Everything from the first quote to the closed period.
Sales
Quotes with revisions, sales orders with shipment groups and drop-ship lines, invoices, payments, coupons, price lists with tier breaks, tax rates.
Operations
Multi-warehouse stock, purchase orders and receiving, pick tickets, carrier rates and labels, PDF documents for every step.
Accounting
Chart of accounts, fiscal periods, and journal entries posted from documents by rules you configure. Trial balance checks included.
CRM
One record per person or organization, with merge, undo and erasure. Leads, pipelines, tasks, communications, and imports from another CRM.
Qwik storefront
A fast, themeable Qwik City shop that reads the ERP live, plus a REST API with an OpenAPI 3 schema if you would rather build your own.
Built to extend
Plugins add navigation, widgets, payment gateways, carriers and integrations. Signed webhooks, custom fields and renameable nouns, no fork needed.
Screenshots
A real back office, not a mockup.
Every image is a capture of the Fincas back office running with demo data.
A package, not a fork
Install it. Extend it. Keep upgrading.
Fincas ships as a Python package. Your deployment is a small Django project that imports its settings and URLs, so upgrades are a version bump, not a merge. Plugins add what your business needs without touching core files.
- Python 3.12, Django 6.0, PostgreSQL 17
- One company per instance
- A documented migration and deprecation policy
- Docker Compose, systemd or Fly.io
