What does Materiality mean in accounting?
Quick definition
Financial reportingThe relative importance, when measured against a standard of comparison, of any item included in or omitted from books of account or financial statements, or of any procedure or change in procedure that conceivably might affect such statements. This term guides how bookkeepers record, classify, and explain related transactions in routine financial reporting.

Examples
Expense the trim router, capitalize the saw
You run a cabinet shop. On March 12, a hardware store rings up a $47 trim router, and an equipment dealer bills $7,240 for a used sliding table saw. The router is not important enough next to March's statements to live on the balance sheet: enter it to Tools so March's P&L takes $47. The saw is important enough that expensing it would swing March profit and hide the machine, so you capitalize the $7,240 to Equipment. Materiality is that comparison against the statements, not the plywood you issue to jobs.
One missed December bill is still material
You run an irrigation company. On January 6 you find a $4,180 December 27 bill from an irrigation supplier for a commercial valve manifold installed at an HOA on December 29. December is already closed, and you leave it out because it is only one invoice. That omission is large enough, next to December job cost and accounts payable, to change the statements: December profit looks high and January will absorb a cost it did not earn. Materiality is not a count of invoices. Backdate a December bill (or post an adjusting entry) so the statements pick up the manifold.
Why it matters
Materiality is whether an amount, an omission, or a change in procedure is important enough, compared with the rest of the books, to change how the financial statements read. You will not apply it to every bank-feed line; it shows up at close, on a CPA review, and whenever you decide whether a small error or a low-cost purchase is worth fixing. Ignore it and you either reopen last month for noise that would not move profit, or you leave a large cutoff or classification miss because it was only one line. This is not about inventory materials; it is about relative importance against the statements you already have.
