Client-Ready Contract & Invoice Clauses
Structuring Professional Invoices and Passing Payment Fees
Invoicing is where contract pricing meets real cash collection. Incomplete invoice line items, ambiguous payment terms, and unexpected credit card processing fees are the most common causes of delayed client payments.
Every client invoice should feature clean itemization: specific dates of service, brief deliverable descriptions, logged hourly units, clear subtotal calculations, and explicit payment due dates (such as Net 14 or Net 30).
When accepting credit cards, digital payment gateways (like Stripe) deduct 2.9% + $0.30 per payment. For a $5,000 invoice, that represents a $145.30 processing deduction. Use our inverse fee calculation to ensure you net your exact target.
