Best Practices

Invoice Numbering

Use a consistent format:

• INV-YYYY-NNN (INV-2024-001)
• YYYY-MM-NNN (2024-01-001)
• CLIENT-NNN (ABC-001)

Payment Terms

Standard options:

• Net 15: Large enterprises (they take forever anyway)
• Net 30: Standard for most clients
• Due on receipt: Small projects, new clients
• 50/50: 50% deposit, 50% on completion
• Milestone: Payment at defined project stages

Cash Flow Tips

1. Invoice immediately — don't wait until month-end
2. Require deposits — 50% upfront for new clients
3. Offer early payment discounts — 2/10 Net 30 (2% off if paid in 10 days)
4. Charge late fees — and enforce them
5. Stop work on overdue accounts — protect yourself
6. Use online payments — easier for clients = faster payment

Red Flags

Watch for these warning signs:

• Client questions your rates after agreement
• "The check is in the mail" (repeatedly)
• Asks to pay after project completion (no deposit)
• Disappears when invoice is due
• Wants to change payment terms mid-project

Tools Integration

Accounting Software:

• QuickBooks, Xero, FreshBooks — sync invoices
• Automatic reconciliation
• Tax reporting

Payment Processors:

• Stripe — credit cards, ACH
• PayPal — widely accepted
• Wise — international transfers
• Bank transfer — lowest fees

Time Tracking:

• Harvest, Toggl, Clockify
• Auto-generate invoices from time entries

Common Mistakes

1. Not invoicing promptly — delays payment by weeks
2. Unclear payment terms — confusion leads to delays
3. No late fees — clients have no incentive to pay on time
4. Ignoring overdue invoices — they don't get better with age
5. No deposit for new clients — high risk of non-payment
6. Mixing personal and business — tax nightmare
7. Not tracking 1099s — IRS penalties
