# The Cimplify Manual > The manual for operating a business on Cimplify. It starts with modelling: turning what a business sells into products, prices, schedules, and stock that behave correctly. Written first for AI agents setting businesses up, and for the people working alongside them. Notes for agents: - Every page has a Markdown twin at `/llms.mdx` — e.g. `/docs/retail` becomes `/llms/docs/retail.mdx`. Fetch /llms-full.txt for the entire manual in one request. - Core method: for each thing a business sells, ask "what moves?" — a thing (retail), a thing made from ingredients (food), or time (service). The answer sets the product type, which decides inventory, scheduling, and fulfilment. - The decision tree in "The mental model" classifies any item deterministically; the first matching rule wins. - Product types: Product (retail or food good), Service (a booking), Digital (access/rights), Bundle (fixed package), Composite (build-your-own). - Common errors to avoid: a capacity number where distinct physical units exist (use resource types); variants for products a shopper compares (use separate products); recurring products without a billing plan; structural facts hidden in notes/metadata. ## Pages - [Bookable resources](https://manual.cimplify.dev/llms/docs/bookable-resources.mdx): Rooms, tables, vehicles, courts, chairs, parking, spaces. How to model the physical thing a booking occupies — the three consumption modes, assignment timing, and when a capacity number is a trap. - [Bundles & build-your-own](https://manual.cimplify.dev/llms/docs/bundles-and-composites.mdx): Selling several things as one line: fixed packages the merchant assembles (bundles) vs. let-the-customer-choose (build-your-own / composites). When to use each and how each is priced. - [Mistakes to avoid](https://manual.cimplify.dev/llms/docs/edge-cases.mdx): The traps that quietly break a setup, the warning signs you've modelled a workaround instead of the truth, and a checklist to model anything cleanly. - [FAQ](https://manual.cimplify.dev/llms/docs/faq.mdx): Direct answers to the questions merchants and agents ask most when modelling a business on Cimplify. - [Food](https://manual.cimplify.dev/llms/docs/food.mdx): Things you make from ingredients: recipes, sizes that use more, waste, modifiers and build-your-own, allergens, and the kitchen workflow. Also covers light manufacturing. - [Getting started](https://manual.cimplify.dev/llms/docs/getting-started.mdx): A practical walkthrough from an empty account to your first product, menu item, or bookable service — with the order to do things in and the decisions you'll face. - [Glossary](https://manual.cimplify.dev/llms/docs/glossary.mdx): Every term used in this guide, in plain language, with a pointer to the chapter that covers it. - [Start here](https://manual.cimplify.dev/llms/docs.mdx): How to set up any business on Cimplify so the data fits what you actually do.

Learn to see them and you can model anything. - [Organizing your catalogue](https://manual.cimplify.dev/llms/docs/organizing-the-catalog.mdx): Categories, collections, tags, global taxonomy, and sales channels — how products get grouped, found, and routed to the right place once they're modelled. - [Pricing & extras](https://manual.cimplify.dev/llms/docs/pricing.mdx): How a price is built up, add-ons and custom fields that change it, tax-inclusive vs exclusive, deposits, discounts, and subscriptions and instalments. - [Retail](https://manual.cimplify.dev/llms/docs/retail.mdx): Things you sell and hand over: products, variants and axes, sizes and colours, stock, conditions, and the rules for when something is a variant and when it's a separate product. - [Services](https://manual.cimplify.dev/llms/docs/services.mdx): Time you sell over a calendar: appointments vs multi-day stays, duration, capacity, availability, staff, deposits, cancellation and reschedule policy, and multi-day check-in/out. - [Salons, clinics & appointments](https://manual.cimplify.dev/llms/docs/scenarios/appointments.mdx): Modelling businesses that sell a person's time: salons, spas, tattoo studios, clinics, photography, tutoring, consulting, pet grooming, driving schools.
