Business Logic

Business logic is the layer of an application that encodes the actual rules, conditions, and calculations governing how the software should behave to correctly reflect real-world business requirements — as distinct from the UI layer (how things look) or the data layer (how things are stored). "A customer gets free shipping if their order exceeds $50, unless they're in a restricted delivery zone, in which case a flat $15 fee applies regardless of order size" is business logic. In traditional software development, business logic lives in backend code (functions, conditionals, service classes); in no-code platforms, it lives in visual workflow steps, formula fields, and conditional branches — but the underlying concept is identical, and getting it right is equally hard regardless of whether you're expressing it in Python or in a Bubble workflow editor. Why it matters: business logic is where most real-world software complexity actually lives — not in the UI (which templates and component libraries have largely commoditized) and not in basic CRUD data storage (which every database app handles natively), but in the accumulated edge cases, exceptions, and conditional rules that reflect how a specific business actually operates. This is precisely why no-code platforms invest heavily in expressive conditional logic and formula systems — a form builder or database app is only as useful as its ability to express real business rules, not just store flat data. How it works: no-code platforms typically express business logic through some combination of conditional workflow branches ("if X, then do A; else do B"), formula/calculation fields (spreadsheet-style expressions computed from other fields, e.g., `IF(Order_Total > 50, 0, 15)` as a shipping-fee formula), and multi-step workflows with sequential conditions. Worked example — encoding a tiered commission structure as business logic in Airtable + an automation: an Airtable formula field calculates `IF(Deal_Value > 100000, Deal_Value * 0.15, IF(Deal_Value > 25000, Deal_Value * 0.10, Deal_Value * 0.05))` — a nested conditional expressing "15% commission on deals over $100k, 10% on deals $25k–$100k, 5% below that." A downstream Make automation then watches for `Stage = Closed Won`, reads this calculated commission field, and creates a payout record in the finance system — the entire commission policy of the company, expressed and enforced without a single line of traditional code, but requiring exactly the same rigor in getting the edge cases right (what happens at exactly $100,000? what about deals in a different currency?) that a software engineer would apply writing the equivalent function.
