"Talk business" is a commonly used phrase that refers to having a conversation about work-related matters. This phrase may be too direct or formal for some situations, which is why it's important to have a variety of synonyms on hand for more casual or informal settings. One alternative might be to suggest "discussing opportunities," which conveys a sense of exploration or collaboration. "Brainstorming solutions" is another option that focuses on problem-solving rather than negotiation. For a more direct and informal approach, "get down to brass tacks" puts the emphasis on cutting through small talk to focus on the important issues. Whatever the phrasing, the goal is always clear communication and successful outcomes.
