# What lives where

> Products, materials, suppliers, technicians, territories, checklist templates and agents: which system you type each into

export const Touches = ({systems}) => <p>
    <strong>Systems involved:</strong>{" "}
    {systems.split(",").map((s, i) => <span key={s}>
        {i > 0 ? " · " : ""}
        <a href={"/systems/" + s.trim()}>{s.trim().replace(/-/g, " ")}</a>

Everything the business runs on is typed into Zoho once. The engine copies it to our side within seconds, and for the things money touches it makes the QuickBooks record too. Nobody types setup data into QuickBooks or the app. Which system owns each record after that is on [Who is the source of truth](/systems/who-is-the-source-of-truth).

| Setup data                  | Typed in                      | What the engine makes from it                                                                                                                                                                       |
| --------------------------- | ----------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

| Supplier and its branches   | Zoho, **Vendors**             | A supplier on our side with its branches; each branch gets a Street View picture; see [Add a supplier and its branches](/handbook/catalog-and-staff/add-a-supplier)                                 |
| Technician                  | Zoho, **Technicians**         | A technician on our side, and an app login when the record has an email; see [Add a technician](/handbook/catalog-and-staff/add-a-technician)                                                       |

## Edits and deletes

An edit in Zoho reaches our side within seconds, and a product's price change reaches QuickBooks after it. Deleting a product, supplier, technician, territory or agent in Zoho switches it off on our side; nothing is removed, and a deleted product's QuickBooks item goes inactive. A checklist template deleted in Zoho is removed on our side with its questions.

## What does not cross

* A technician's home location stays in Zoho.
* A territory's map area lives only on our side.
