You use this category for the running care, maintenance and updating costs of a website or homepage that you use for your letting activity. What is meant in particular is the costs of keeping an existing website **technically functional, secure and up to date** without a completely new website or a substantially new web presence being created in the process. A letting-related website can serve, for example, to: * present available apartments or other let properties, * provide information to prospective tenants, * receive contact or viewing enquiries, * provide information for existing tenants, * or present your letting activity or property administration to the outside world. #### **What can be posted to this category?** Costs can be posted here in particular for: * the technical maintenance of an existing website, * regular security updates, * updates to the content management system used, * remedying technical errors, * repairing faulty functions, * adapting to new browser or technical requirements, * updating existing content, * replacing outdated texts or images, * maintaining property listings, * smaller layout adjustments, * optimising the mobile display, * regular data backups as far as these are part of the website maintenance, * or running maintenance contracts with a web agency. **Example: a running maintenance contract for your website** You run a website on which you present your available rental apartments. A web agency takes on: * security updates, * technical error fixing, * updating the system, * smaller changes to existing pages. For this you pay **€50 a month** Annual amount: **€50 × 12 = €600** This **€600** can in principle be posted to the **"**[**Maintenance for a website, homepage etc.**](/en/anleitung/einnahmen-und-ausgaben/buchhaltung-erweiterung/10147400-wartung-fuer-website-homepage-etc.md)**"** category. #### Creating a website for the first time This category is intended only for the running maintenance, care, technical updating or smaller adjustment of a website that already exists. **Creating** a new website **for the first time** is to be distinguished from that. Smaller creation costs of up to **€800 net** can be posted, as far as they serve directly to advertise the letting activity, to the **"**[**Advertising costs (sponsorship, advertising, business cards etc.)**](/en/anleitung/einnahmen-und-ausgaben/buchhaltung-erweiterung/10148400-werbekosten-sponsoring-werbung-visitenkarten-etc.md)**"** category. #### **Distinguish a software licence from website maintenance** Immodio has the category: **"**[**Software licences, software, SaaS, Immodio, software rental**](/en/anleitung/einnahmen-und-ausgaben/buchhaltung-erweiterung/10107700-softwarelizenzen-software-saas-immodio-softwaremiete.md)**".** It should be distinguished from website maintenance itself. **Example** Your web agency charges: * **€600** for technical **maintenance and updating**. These costs are posted to the category → "[Maintenance for a website, homepage etc.](/en/anleitung/einnahmen-und-ausgaben/buchhaltung-erweiterung/10147400-wartung-fuer-website-homepage-etc.md)" * In addition you pay **€120** a year for an independent **software or plugin licence**. Where this is actually a pure software licence, these costs are posted to the category → "[Software licences, software, SaaS, Immodio, software rental](/en/anleitung/einnahmen-und-ausgaben/buchhaltung-erweiterung/10107700-softwarelizenzen-software-saas-immodio-softwaremiete.md)". {% hint style="info" %} With an invoice containing maintenance, licences and further services together, the individual services have to be posted separately accordingly. {% endhint %} #### **Assignment in Immodio** With this category the assignment is to the **owner**. Select the owner whose letting activity the website actually serves. #### **Do not recover from the tenant** The maintenance of a landlord's website or homepage is part of the **advertising or administration of their letting activity**. These costs do **not** arise from the running intended use of the let building and are not operating costs of the tenant. The **"Recoverable in the operating cost statement"** switch therefore has to stay **disabled**. #### **Which documents should you keep?** Keep in particular: * the **invoice from the web agency or service provider**, * the maintenance or service contract, * proof of payment, * a description of the work carried out, * with mixed use, the calculation of the share relating to the letting activity, * separate invoices or items for software licences, hosting or other additional services,
