Contact and account records designed for B2B deal complexity: accounts as the company level, contacts as the individuals within them, and deals connected to both with visibility into every relationship. Contact records: name, title, email, phone, LinkedIn URL, department, contact owner, and custom fields relevant to your qualification (decision-making authority, budget ownership, engagement level). Account records: company name, website, industry, company size, HQ location, account owner, and the deal history showing total closed revenue from this account. Contact role tracking on each deal: economic buyer, champion, technical evaluator, legal reviewer, and custom roles defined per your sales methodology -- the stakeholder map that tells a rep who they need to influence before the deal closes. Account hierarchy for enterprise accounts with multiple subsidiaries or business units: parent account linked to child accounts, with deal value rollup to the parent for total account revenue visibility. Contact enrichment integration with Clearbit or Apollo.io: new contacts enriched automatically on creation with company data, LinkedIn profile, and company technology stack -- reducing the manual research time per new prospect. Duplicate detection at contact creation using email address and fuzzy name matching: flagging potential duplicates for review before a second record is created rather than requiring a weekly deduplication exercise. Contact merge: combine two duplicate records into one, preserving all activity history, deal associations, and email log from both records.
