What is Spine?

Spine runs a small service or project business — a contractor, an interior design studio, a fabricator, an electrical or plumbing firm, a maintenance company — from one place, on your own server.

It follows the way the work actually flows:

Enquiry → Quote → Job → Invoice → Payment → Books

• Sales: contacts, a lead pipeline, meetings, a catalogue of what you sell, and quotes your customers read and accept online.
• Jobs: an accepted quote becomes a job with milestones, variations, a crew, costs and retention. Invoice it as the work is done.
• Billing: invoices, credit notes, payments, statements and automatic reminders, with tax on every line (including GST in India).
• Purchases: vendor bills, expenses with receipts and approvals, and vendor payments.
• Books: every document posts its own balanced entries, so your profit and loss, balance sheet, cash flow, aging and job profitability are always current. You never type a debit or a credit. Export to Tally when your accountant needs it.
• The field app: your crew see their jobs, mark milestones done, take site photos and send expenses from their phones, even without signal.
• Your team: Owners, office Staff (with rights set by Teams) and Field crew each see what they need, and nobody sees what they shouldn’t.

Your server, your data

Spine is free, open-source software (AGPL-3.0). You run it on your own machine or a server you rent, with Docker. Your data never leaves it: there’s no account with us, no telemetry, and nothing calls home except an optional daily check for a new version. Backups, restores and upgrades are each one command.
