A few words carry precise meanings in BlossomERP, and the whole manual leans on them.
A document is one piece of business paperwork inside the system: a sales order, a goods receipt, a payment, a work order. Documents are numbered (SO-1042, GR-0117) and each one moves through a workflow: draft, then approved, then posted.
Posting is the moment a document stops being paperwork and becomes fact. A posted document writes its entries into the company's books — the general ledger, the accountant's record of every movement of money — and moves stock where stock is involved. Posted documents never change afterwards; mistakes are corrected with new documents, never by editing history. Chapter 1 explains the lifecycle in full: 1.5 The life of a document.
A record is anything you keep and look up: a customer, a supplier, a product, an employee. Records you open get a 360° view — everything about them on one page, arranged the same way everywhere.
An enquiry is a question you ask the data on screen ("what do we hold in the Lagos warehouse?"); a report is a shaped, printable answer ("stock aging, as at month-end"). Both are explained wherever they belong, module by module.
Finally, a switch is a company preference that turns a capability on or off, and a module is a whole area of the application that can be switched on or off as one. Chapter 0 is about both.
