You transfer material from one warehouse to another, and anything below minimum shows in red and in its report. ### Automatic replenishment attendo compares minimum levels and the materials your plans and work orders need with stock and what is already on order. You see the 90-day shortfall per product, and it proposes the purchases. ### One order per supplier You choose a date range and attendo groups what is missing by supplier. You generate one order per supplier in a single step, and each one goes out by email with its PDF. ### Lots, expiry, serials and warranties You track lots with their expiry date and serial numbers with their warranty. Every part that goes out is charged to the asset where it was installed and to the technician who used it. ### Codes and references Each product stores its references: your ERP code, its SKU and several barcodes, without overwriting the internal one. The catalog and the inventory are loaded and counted from Excel. ### Suppliers and their portal Each supplier has its own record, and purchases are grouped by supplier. With the [supplier portal](https://attendo.me/en/modules/customer-portal), your suppliers and subcontractors work with their own login, with no license. ## Step by step This is how it is used day to day, on the same document as the rest of the modules. ### Step 1 · You plan the materials In each maintenance plan and each work order. ### Step 2 · You review the shortfall Planned needs and minimums against stock and what is already on order, 90 days out. ### Step 3 · You generate the orders One per supplier, in a single step, with its PDF by email. ### Step 4 · You confirm usage The technician confirms what was used, and only that deducts stock. ## It fits every area Industry solutions [attendo CMMS](https://attendo.me/en/cmms) [attendo Field Service](https://attendo.me/en/field-service) [attendo After-Sales](https://attendo.me/en/after-sales-service) ### Industries that use it - [Repair and after-sales service](https://attendo.me/en/industries/after-sales-repair): The part on order, always in view - [Manufacturing and industrial plants](https://attendo.me/en/industries/manufacturing): The spare part, located and on time - [Energy and renewables](https://attendo.me/en/industries/energy-renewables): Every visit, with its route and history - [Testing, inspection and laboratories](https://attendo.me/en/industries/testing-inspection): Every instrument, with its calibration - [And any other business](https://attendo.me/en/industries): attendo can be set up for any line of business.

It is not the most expensive part or the most used one: it is the one you cannot get quickly. Field work ### First-time fix rate FTFR The first-time fix rate is the percentage of jobs resolved without having to go back. Maintenance ### MTTR Mean time to repair MTTR (mean time to repair) is the average time it takes to bring equipment back into service after it fails. It measures responsiveness, not reliability.

That way stock reflects what was actually installed, not what was planned. ### Can I track the stock in each van? Yes. Each vehicle has its own warehouse, with its movements and restocking. ### How do orders reach the supplier? By email, with their PDF. The generator creates one order per supplier in a single step, and orders can also be canceled in bulk. ### Does it check stock in my ERP? Yes, with an MCP connector: from the work order you ask whether a part is in stock, and the answer is added to the record. ### Does it track lots and serial numbers? Yes. Each lot keeps its expiry date, and each serial number, its warranty. ## Try it with your processes We will show it to you with your own document types and the way you work.
