Balancing Cash Flow and Relationship

Paying right at the due date (not early, not late) maximizes your own cash flow without damaging the relationship or risking late fees. Paying consistently early can sometimes be leveraged into better pricing or priority treatment. Only if it's a deliberate choice, not just carelessness about when payments could have been delayed.

A Simple Payment Process

  1. Verify the invoice against the PO and receiving record (3-way match)
  2. Schedule payment for the actual due date, not immediately on receipt
  3. Track payment against the specific invoice, not just a running total owed to that supplier

What Late Payments Actually Cost

Beyond late fees, consistently late payments are one of the fastest ways to lose priority treatment during a supply shortage. Suppliers naturally prioritize their most reliable payers when stock is tight.

This connects to Cash Flow Guide. Payables timing is one half of the cash flow equation, receivables timing is the other.

Checklist

Common Mistakes

Paying invoices as soon as they arrive without a 3-way match. This skips a basic check that catches billing errors before money leaves the business.
Treating all payment timing as first-come-first-served. Paying right at the due date, rather than early or late, is what actually protects cash flow.
Not tracking payments against specific invoices. A running total owed makes it hard to catch discrepancies when a dispute comes up.
Underestimating the cost of chronic late payment. Beyond fees, it can mean losing priority treatment exactly when a shortage makes that treatment valuable.

Verifying the invoice against the purchase order and the receiving record before scheduling payment, which catches billing errors before they're paid.
