Pet Business Bookkeeping: Tip Tracking and Supply Inventory Done Right

By Victor Schiano, Founder of GuidedLedger | 7 min read

Groomer tips and shop supplies are two of the most-mishandled items in pet businesses. Here's how to handle both without creating tax problems.

Pet businesses look simple from the outside — wash dogs, board cats, sell treats — but the bookkeeping has more sharp edges than most owners realize. The two most common ways to get in trouble: mishandling tips for groomers and bathers, and ignoring supply inventory until margins quietly collapse.

Tips Are Wages — Yes, Even Cash Tips

The IRS treats tips as taxable wages. If your groomers and bathers are W-2 employees, tips need to flow through payroll: reported by the employee, taxes withheld, and reported on their W-2. If you handle tips informally — cash in an envelope, Venmo direct to staff — you're creating a payroll tax liability without realizing it. The IRS has gotten very aggressive about this in service businesses.

Setting Up Compliant Tip Reporting

Three steps:

  1. Pick a tip method (cash, card-pooled, Venmo, app).
  2. Have employees report tips daily or per pay period — most POS systems support this.
  3. Run tips through payroll: include in gross wages, withhold appropriate taxes, report on W-2 and 941.

For 1099 contractors (true independent groomers renting a chair from you), tips paid directly by clients are their own income to track — but if tips flow through your business first, they're still subject to reporting.

Supply Inventory: The Silent Margin Killer

Shampoo, conditioner, brushes, blades, treats, leashes, food, retail product — pet businesses run heavy on supplies. Without inventory tracking, two things happen:

  • You over-order, tying up cash and creating expired stock.
  • Your gross margin number is wrong because purchase timing distorts COGS.

Practical Inventory for Pet Shops

You don't need enterprise-grade inventory software. You need:

  • A physical count of major supply categories at month-end.
  • An adjustment entry that books true COGS for the month (purchases + beginning inventory − ending inventory).
  • For retail product, perpetual inventory through your POS (Square, Gingr, Time To Pet, MoeGo).

Bonus: Per-Service Profitability

Once supplies and labor are tracked correctly, you can finally see whether grooming, boarding, daycare, and retail are each pulling weight. Most owners are surprised by what they find.
