Electronic and Precision Equipment Repair and Maintenance

NAICS 811210 · Repair and Maintenance · SBA size standard: $34 million average annual receipts

Shops that repair and maintain electronic and precision equipment receive customer-owned gear, log serial numbers and symptoms, source parts, schedule bench work, perform repairs or calibrations using certified test equipment, document every step against manufacturer procedures, and return the items via shipment, pickup or on-site dispatch. Specialists turn intake forms into tagged work orders, convert approved diagnoses into parts orders and bench schedules, track inventory and calibration due dates, compile audit-ready records, and handle customer notifications. Repair procedures, test equipment accuracy and any required authorizations stay with the technicians.

Workflows

Equipment intake and diagnosis

Starts when: A customer submits a repair request by form, email, phone or drop-off

  2. Assign a unique work order number and attach physical tag to the equipment
  3. Perform initial visual and functional inspection
  4. Draft diagnosis summary and cost estimate
  5. Send the estimate for customer approval before any disassembly

Watch for: Serial numbers and customer equipment must never be swapped; High-value or sensitive items require signed chain-of-custody at intake

Parts procurement and inventory

Starts when: After diagnosis approval and weekly

  1. Identify required parts from manufacturer diagrams and service manuals
  2. Check in-house inventory levels
  3. Draft purchase orders for vendors and track incoming shipments against each work order
