Repair Karte started at a guitar repair bench. Setups, fret work, electronics and wind instrument repairs, with estimates customers approve online and a history for every instrument by serial number.
An example of a instrument repair in Repair Karte (the customer and item are made up). The plan for each step is written under it; see pricing.
Pick the item type and the usual work in a tap, write the symptom, and print a claim tag (PDF on Letter or A4). The customer signs on screen.
