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.
