🧠 Grammar / Strategy Focus

📐

Relative clauses add extra information about a noun. Use "who/that" for people, "which/that" for things, and "whose" for possession. In TOEIC Part 5/6, watch for whether the clause is essential (no commas) or non-essential (with commas — cannot use "that" in a non-essential clause).

Song Hong Manufacturing recently updated its ordering process to reduce delays for customers who place bulk orders. Under the new system, any order over 500 units automatically receives a 10% discount, and customers whose orders are confirmed before noon are guaranteed same-day processing. Invoices, which are now sent electronically instead of by mail, must be paid within 30 days to avoid a late fee. Customers who need an extension should contact the accounts department before the due date. Since introducing electronic invoicing last quarter, the company has reduced payment delays by 35% and cut its average invoice-to-payment time from 45 days to 29 days.
