Veterinary practices use working capital lines of credit to fund pharmaceutical and specialty diet inventory, bridge payroll between peak appointment cycles, and cover seasonal demand fluctuations -- with revolving lines of $25K--$500K available to practices with 620+ FICO, 12+ months operating history, and $15K+ average monthly deposits.
Veterinary practices carry a working capital burden that most professional service businesses do not: pharmaceutical inventory (vaccines, antiparasitics, pain management, antibiotics), controlled substances (Schedule II--IV anesthesia and analgesic medications), specialty prescription diets, and surgical supplies must all be stocked before appointment revenue arrives. A mixed small-animal/exotic practice may carry $30,000--$80,000 in pharmacy and inventory at any given time. A revolving working capital line provides the draw-down flexibility to manage inventory replenishment, payroll between high-volume appointment weeks, and the growing lag from pet insurance reimbursement -- without liquidating equipment or taking on term debt for a recurring cash-flow pattern.
Veterinary practice cash flow has two structural working capital pressures: (1) Inventory pre-funding -- pharmaceutical distributors (Covetrus, MWI Veterinary Supply, Henry Schein Animal Health) typically offer 30-day net payment terms; a practice with $40K/month in drug and supply purchases must fund that inventory before it converts to appointment revenue; (2) Seasonal appointment cycles -- small animal practices experience peak demand in spring/summer (flea/tick prevention, annual wellness exams, boarding health certificates) and lower volume in mid-winter; payroll does not flex with appointment volume, creating predictable cash-flow gaps in slower months. The Federal Reserve H.15 Statistical Release reports prime rate and benchmark rates used to price revolving lines of credit -- variable-rate lines are indexed to prime + spread. IRS Publication 535 covers business interest expense deductibility -- interest on working capital lines drawn for legitimate business purposes is deductible.
The SBA 7(a) program includes working capital as an eligible use -- a practice can bundle working capital into a broader SBA 7(a) term loan alongside equipment or real estate. For practices that primarily need a revolving working capital line, the SBA CAPLine program provides revolving credit facilities up to $5M under SBA guarantee -- the Seasonal CAPLine and Working Capital CAPLine are the most relevant variants for veterinary practices with predictable seasonal revenue patterns. SBA working capital is not the fastest product (30--90 days to fund), but produces the lowest rate on qualified revolving facilities.
Veterinary working capital underwriters evaluate: DEA controlled substance inventory -- a practice with significant controlled-substance revenue (ketamine, opioids, benzodiazepines) must have active DEA registration; lenders treat the DEA registration as a prerequisite for the pharmacy revenue stream to be credited in DSCR calculations; distributor credit utilization -- practices with maxed-out distributor credit lines (Covetrus, Henry Schein) signal working-capital stress that a revolving line of credit is designed to resolve; pet insurance reimbursement growth -- practices with significant Trupanion or Nationwide reimbursement volumes should document the 30--45 day reimbursement lag for lender DSCR normalization; and associate DVM attrition -- the departure of an associate DVM can drop monthly revenue 20--35% overnight; a working capital line sized at 2--3 months of operating expenses provides a payroll bridge during recruitment.
