Self-hosted accounting with invoicing, inventory, and reports

Alternative to QuickBooks Online

Bigcapital is a self-hosted, open-source accounting system for small and medium businesses that records sales and purchase invoices, tracks expenses and inventory, and produces financial reports from a double-entry ledger. It runs in Docker with a NestJS API and React interface, and pairs the AGPL-licensed self-hosted edition with a managed cloud option for teams that prefer not to run servers.[1][2]

Quick verdict

Small businesses and accountants that want self-hosted double-entry books with inventory and multi-currency journals benefit most from Bigcapital. Its concrete strength is invoice-to-payment workflow with expenses, bank reconciliation, and financial reporting against your own ledger, all under your control. The material constraint is operational and licensing overhead: self-hosting needs Docker server administration, the AGPL copyleft binds how you share modified versions, and current managed-cloud pricing could not be verified from official sources. If you want self-hosted accounting with inventory on your own infrastructure, choose Bigcapital; if you need turnkey SaaS billing with a published per-seat price, choose QuickBooks or a verified cloud plan.[1][2][3]

Key features

  • Double-entry ledger Every transaction posts to a real double-entry journal, so the books stay balanced and auditable rather than approximating accounting in spreadsheets.[1][2]

  • Sales invoicing and estimates Create invoices and estimates, send them to customers, and track what is owed and paid from the same record.[1][2]

  • Bills and expense tracking Record purchase invoices, bills, receipts, and payments, and categorize spending so costs stay organized.[1][2]

  • Inventory and warehouses Track stock quantities and movements across warehouses with valuation, which suits sellers of physical goods.[1][2]

  • Multi-currency journals Keep books across currencies with exchange-aware entries, useful for businesses that buy or sell across borders.[1][2]

  • Bank reconciliation Match imported bank activity against ledger entries so statements and books agree at period end.[1][2]

  • Online payments Collect customer payments through gateways including Stripe and PayPal, connected to the invoice record.[1][2]

  • Reports, roles, and API Generate profit-and-loss, balance-sheet, and cash reports; restrict staff and accountants with role-based access; and extend or integrate through the API.[1][2]

Who will love it

  • Self-hosting small businesses Teams that want their ledger on their own Docker infrastructure get a full accounting core without a per-seat subscription for the software itself.[1][2]

  • Goods sellers needing inventory Businesses tracking stock alongside sales and purchases get warehouses and valuation inside the same books.[1][2]

  • Accountants needing double-entry journals Multi-currency journals with bank reconciliation and financial reports suit accountants keeping formal books for clients.[1][2]

Who should avoid it

  • Teams without server administration Self-hosting means running Docker services and your own database, so teams with nobody to operate infrastructure should prefer the managed cloud or a SaaS product.[1][2]

  • Buyers needing verified cloud pricing Current official per-month cloud pricing could not be established from reachable official sources, so budget approval that requires a published price remains blocked.[1][2]

  • Embedders avoiding strong copyleft The AGPL-3.0 license requires sharing modified versions with network users, which rules out embedding it in proprietary offerings without legal review.[1][2]

Deployment and fit

Self-host or cloud Run Bigcapital on your own infrastructure with Docker, or choose the managed cloud edition when you prefer not to manage servers.[1][2]

Web interface and stack The app works from a web browser over a NestJS API and React interface backed by MySQL, which suits teams already comfortable operating that stack.[1][2]

Questions worth asking

What is the best Bigcapital alternative for non-technical users?

QuickBooks Online is the positional alternative named in Bigcapital's own catalogue relationships: a vendor-run cloud with no server administration. If even hosted bookkeeping feels heavy, a simpler invoicing-only tool may fit, though that choice was not separately researched.[1][2]

Is Bigcapital really no-code?

Day-to-day bookkeeping is visual and no-code in the web interface. Self-hosting is the exception: installing it on your own server needs Docker and server administration.[1][2]

How much does Bigcapital cost per month?

The self-hosted AGPL edition carries no software license fee beyond your own hosting costs. A managed cloud edition exists, but its current official per-month price could not be verified from reachable official sources, so recheck pricing before deciding.[1][2]

Can you self-host Bigcapital?

Yes. Bigcapital deploys on your own infrastructure with Docker alongside its API, web interface, and MySQL database, or you can use the managed cloud instead.[1][2][3]
