Sales and invoicing

For a business that sells services or goods on a quote and an invoice: clients, proposals your clients sign online, and invoices from an accepted letter.

What it does

A client book

Every client with its contacts, documents, letters, work and renewals in one place, and a catalogue of what you sell.

Proposals signed on a link

The client opens a link and signs by drawing. Nobody needs an account to sign.

The Owner signs before it goes out

A letter reaches a client, and an invoice is issued, only after the Owner has signed it.

Invoices from an accepted letter

An accepted letter becomes its invoices, with the tax worked out on each one.

Work and renewals

Work in progress for each client, and renewals raised before a service lapses.

Who owes what

Receivables by client with ageing, matched against the bank statement.

Business lines

Set up for how you sell

Pick the kind of business you run and the catalogue, the work steps and the wording start from it. All of it is yours to change.

What it is not for

sieraOS records what you sell and invoice, not what you hold.

  • Stock levels and purchase orders.
  • Sales at a counter or till, and a restaurant's walk-in orders.
  • Hotels and homestays, which are bookings.
  • Farming and fishing, which sell commodities.

Who signs

A person signs each step that matters. The model reads and proposes.

  • The client signs the letter by drawing on a link
  • The Owner signs a letter before it reaches a client
  • The Owner signs an invoice before it is issued
