Getting started
What Orin is
One place for clients, products, stock, orders and invoices.

Orin keeps the five things a small business runs on in one place, and keeps them in step with each other. Sell something and the stock moves. Confirm an order and the invoice is one click away. Nothing is entered twice.
The five modules
- Clients — everyone you sell to, with their orders and invoices on the one page.
- Products — your catalogue, with pricing, cost and the margin between them.
- Stock — levels derived from movements, so history and level can never disagree.
- Orders — a line-item editor with live totals, from draft to fulfilled.
- Invoices — line items, payments, and an overdue state that works itself out.
What Orin is not
Orin is not an accounting package and does not file your returns. It records what you sold, to whom, for how much, and what is still owed. Your accountant takes it from there.
