Professional Invoice Best Practices: Get Paid Faster
A well-crafted invoice does more than request payment—it reflects your professionalism and can significantly impact how quickly you get paid.
The Anatomy of a Perfect Invoice
Essential Elements
Every professional invoice should include:
-
Your Business Details
- Company name and logo
- Complete address
- ICE and IF numbers
- Contact information
- Bank details
-
Client Information
- Company name
- ICE (for B2B)
- Billing address
- Contact person
-
Invoice Specifics
- Unique invoice number
- Invoice date
- Due date
- Reference/PO number
-
Line Items
- Clear descriptions
- Quantities
- Unit prices
- VAT rates
- Line totals
-
Summary
- Subtotal (HT)
- VAT breakdown
- Total (TTC)
- Amount in words
Best Practice #1: Be Clear and Specific
Poor Example:
"Services rendered - 5,000 MAD"
Good Example:
"Website Development Services (March 2024)
- Homepage design and development: 2,000 MAD
- Product pages (5 pages): 1,500 MAD
- Contact form integration: 500 MAD
- Mobile responsiveness: 1,000 MAD"
Best Practice #2: Set Clear Payment Terms
Standard Payment Terms
| Term | Meaning | When to Use |
|---|---|---|
| Due on receipt | Immediate payment | Small amounts, new clients |
| Net 15 | Due in 15 days | Regular clients, services |
| Net 30 | Due in 30 days | Established relationships |
| Net 60 | Due in 60 days | Large contracts, enterprise |
Tips for Payment Terms
- State terms clearly at the top
- Mention late payment fees (if applicable)
- Offer early payment discounts (e.g., 2% if paid within 10 days)
Best Practice #3: Make Payment Easy
Include Multiple Payment Options
- Bank transfer details (RIB)
- Payment links (if available)
- Mobile payment options
- Check instructions
Clear Payment Instructions
Bank Transfer Details:
Bank: [Your Bank Name]
Account Holder: [Company Name]
RIB: [Your RIB Number]
Reference: Please include invoice number
Best Practice #4: Send Invoices Promptly
Timing Matters
- Send invoices immediately after service completion
- For ongoing projects, invoice at agreed milestones
- For retainers, send on the same date each month
Best Days to Send
Studies show invoices sent on Tuesday and Wednesday get paid faster than those sent on Friday or Monday.
Best Practice #5: Follow Up Systematically
Recommended Follow-up Schedule
| Days After Due Date | Action |
|---|---|
| 3 days before | Friendly reminder |
| Due date | Thank you if paid, reminder if not |
| 7 days overdue | First follow-up email |
| 14 days overdue | Phone call |
| 30 days overdue | Formal reminder letter |
| 45+ days overdue | Final notice |
Best Practice #6: Use Professional Formatting
Visual Hierarchy
- Logo prominently displayed
- Clear section headers
- Consistent fonts
- Adequate white space
- Highlight total amount
Color Usage
- Use your brand colors
- Make the "Amount Due" stand out
- Keep it professional (avoid too many colors)
Best Practice #7: Include Relevant Notes
What to Include
- Thank you message
- Payment terms reminder
- Return policy (for products)
- Warranty information
- Upcoming services mention
Example Note:
"Thank you for your business! We appreciate prompt payment within 30 days. Questions? Contact accounts@yourcompany.ma"
Best Practice #8: Automate Where Possible

What to Automate
