Keystone manual.

Keystone runs CRM, company records, contracts, subscriptions, billing, accounting, expenses, banking and tax in one system.

Audience: Revenue, finance and business operations teams Focus: Customer, contract and financial records

Keystone keeps customer records, sold contracts, invoices and the general ledger in one system. A sale, the subscription it creates, the invoice it bills and the journal entry it posts all point at the same customer and company entity.

This manual starts with three overview pages and then moves into detailed guides for each module. API reference, platform setup and integration internals are not covered here.
