First - check if the company meets the size standards for SBA. You will need the correct NAICS code for the company. For some industries, the size standard is based on annual revenue while for others it is based on total number of employees.
https://www.sba.gov/content/small-business-size-standardsIf the company meets the size standards, then have your loan officer ask the company if the LOC helps them retain their workforce during the low points of their revenue cycle. In other words, if the company did not have the LOC to utilize for payroll and other operating expenses while awaiting payment on their receivables, would they have to cut full time jobs to part time, or rely in temporary workers rather than permanent workers?
If that answer is "Yes", have the lender document both the size standards and the job retention as part of the credit approval as the loan meets the definition of Economic Development according to the Q&A.
