It tells you what a whole line, plant or building costs, and how much of that each piece of equipment takes. ## Why you need it Cost per [asset](https://attendo.me/en/glossary/asset) answers “how much does this pump cost me?” But many decisions are made one level up: replacing a line, renegotiating a building contract or investing in a plant. The roll-up carries costs up the tree. The cost of line 2 is the cost of its equipment, plus its groupings, plus anything charged to the line itself. ## What gets added - Labor hours on each job, at the cost of each labor category. - Spare parts and materials used. - Outside services and subcontractor work. All under the same date filter, so you compare like periods. ## An example A packaging line costs $52,000 a year to maintain. The roll-up shows that the filler takes $26,000, half of it. The conversation with management stops being “the line is expensive” and becomes “this machine costs half the line.” These are example figures. ## The usual mistake Charging the same cost at several levels. If a part is charged to the machine and also to the line, the roll-up counts it twice. Each cost goes to the lowest level where it can be identified, and the tree carries it up. ## In attendo In [attendo CMMS](https://attendo.me/en/cmms), any tag has its own costs tab, including group tags such as a line or a plant. It adds up everything below it at every level and shows each one’s share, with labor at the cost of each category and a date filter. - [attendo CMMS](https://attendo.me/en/cmms) ## Where it is used in attendo ### Modules - [Assets and inventory](https://attendo.me/en/modules/assets): Each asset with its own record, QR code, history and readings - [Tags and document management](https://attendo.me/en/modules/document-management): Tags, attachments and files tied to their customer, asset and case - [Reports and dashboards](https://attendo.me/en/modules/reports-and-dashboards): Reports and dashboards for every area, with today’s data ### Industries that use these modules - [IT services and MSPs](https://attendo.me/en/industries/it-services) - [Testing, inspection and laboratories](https://attendo.me/en/industries/testing-inspection) - [Hospitality, retail and multi-site](https://attendo.me/en/industries/multi-site-operations) - [Facility maintenance and services](https://attendo.me/en/industries/facility-maintenance) - [And any other business](https://attendo.me/en/industries) ## Related terms Maintenance ### Asset An asset is any piece of equipment, machine or installation whose maintenance you keep track of: its record, its location, its history and its costs.
