Due to the lack of professional estimators in the majority of small businesses, the estimation procedure becomes even more difficult. This can result in issues such as/span>

  • Miscalculations or errors in the cost estimations of labor or part cost estimations.
  • Presentation that isn’t very professional.
  • Not knowing exactly what has to be done due to a lack of technical and operational understanding.
  • It takes time and effort to repeatedly look for prices and lead times.
