Deep Dive: Switching from Sage Accounting to Bigcapital
Trade-offs, installation & data architecture
What you trade away
Bigcapital lacks Sage's plug-and-play bank feeds, UK tax and MTD workflow, payroll add-ons, and accountant ecosystem, while making the user operate the server.
How to deploy Bigcapital
Official server setup script and Docker-based deployment
What it takes to run
It needs a Linux server, Docker, DNS and HTTPS, database and mail configuration, backups, and upgrades; the hosted product is not the indefinitely free path.
Where your data lives
Books, contacts, invoices, bills, inventory, and settings live in the deployment's MariaDB database, with generated files and attachments on configured server storage.
Why fork Bigcapital instead of vibe-coding a Sage Accounting clone?
Do not mistake the interface for the product. Sage Accounting's durable value is banking, compliance, trust, which a solo one-shot build cannot reproduce responsibly. The prompt therefore builds only the closest honest personal consolation tool.
