Step-by-Step Invoice Management
Set Up Your Invoicing System
Choose invoice software that fits your needs. Look for features like online payments, automatic reminders, and VAT support. Set up your business details, logo, and payment terms once — they'll appear on every invoice.
- Use cloud-based software for access anywhere
- Set up payment gateway integration from day one
- Create invoice templates for different services
Create Clear, Professional Invoices
Every invoice should include: your business details, client details, invoice number, date, itemised services/products, amounts, VAT (if applicable), payment terms, and payment methods.
- Use sequential invoice numbers
- Be specific in line item descriptions
- Always include due date prominently
Send Invoices Promptly
Invoice as soon as work is completed or goods are delivered. The longer you wait, the longer you'll wait for payment. Same-day invoicing is ideal.
- Set a daily invoicing routine
- Use email delivery with payment links
- Confirm receipt for large invoices
Track Payment Status
Monitor which invoices are paid, pending, or overdue. Use your software's dashboard to see your complete financial picture at a glance.
- Check invoice status daily
- Flag overdue invoices immediately
- Know your total outstanding at all times
Follow Up on Overdue Invoices
Don't let overdue invoices slide. Send reminders at set intervals: on due date, 7 days overdue, 14 days overdue. Be professional but persistent.
- Automate reminders where possible
- Have escalation templates ready
- Document all follow-up attempts
Record Payments and Reconcile
When payments arrive, mark invoices as paid immediately. Reconcile with your bank account regularly to ensure accuracy.
- Use automatic payment matching if available
- Reconcile weekly at minimum
- Keep records for 5 years (SARS requirement)
