Essential Invoice Fields
Missing or unclear information is the #1 reason invoices get delayed. Make sure every invoice includes these essential fields.
| Field | What to Include | Why It Matters |
|---|---|---|
| Your Business Info | Name, address, phone, email, logo | Professional appearance, easy contact |
| Client Info | Company name, contact person, address | Ensures invoice reaches right person |
| Invoice Number | Unique sequential number (e.g., INV-2025-001) | Tracking, reference, legal compliance |
| Invoice Date | Date invoice was issued | Establishes payment timeline |
| Due Date | Clear payment deadline | Sets expectations, enables late fee enforcement |
| Line Items | Description, quantity, unit price, total | Transparency about what's being charged |
| Subtotal & Taxes | Subtotal, tax breakdown (GST/VAT), total due | Legal compliance, clarity |
| Payment Instructions | Bank details, accepted methods, online payment link | Reduces friction in getting paid |
Legal Requirements Vary
Different countries have specific invoice requirements (e.g., GST number in India, VAT number in EU). Check local regulations and include all legally required information.
2Clean Layout & Design
A well-designed invoice is easier to read, process, and approve. Good design reduces confusion and delays.
- **Use clear section headings** – Separate your info, client info, items, and totals visually
- **Choose readable fonts** – 11-12pt for body text, avoid decorative fonts
- **Include your logo** – Builds brand recognition and professionalism
- **Highlight the total due** – Make the amount owed prominently visible
- **Highlight the due date** – Equally prominent; no one should miss it
- **Use whitespace** – Don't cram everything together; let the document breathe
- **Align numbers right** – Currency and quantities are easier to scan when right-aligned
Good vs Bad Invoice Design
Pros
- Logo at top for brand recognition
- Clear sections with headings
- Total and due date highlighted
- Payment instructions clearly visible
- Ample whitespace for readability
Cons
- No logo or branding
- Cramped, hard-to-read text
- Total buried in the document
- Due date missing or unclear
- No payment instructions provided
Test your invoice by asking: Can someone find the total and due date in 3 seconds? If not, redesign.
3Writing Effective Line Items
Line items are where disputes start. Clear, detailed descriptions prevent confusion and objections.
Example: Good vs Vague Line Items
Scenario
Vague: "Consulting services - $5,000"
Solution
Better: "Strategy consulting (May 2025): 20 hours @ $250/hr - Brand positioning workshop (8 hrs), Competitor analysis (6 hrs), Marketing roadmap (6 hrs) - $5,000"
- 1**Be specific about deliverables** – "Website redesign" is vague; "5-page responsive website with contact form" is clear
- 2**Include dates or time periods** – "May 2025 services" or "Project Phase 2"
- 3**Show quantities and rates** – Even for fixed-price work, break it down
- 4**Match contract language** – Use the same terminology as your agreement
- 5**Group related items** – Keep the invoice organized and logical
4Payment Terms That Work
Your payment terms set expectations and protect your cash flow. Be explicit and consistent.
| Term | Meaning | When to Use |
|---|---|---|
| Due on Receipt | Pay immediately | Small amounts, one-time clients |
| Net 15 | Due in 15 days | Small businesses, quick turnaround work |
| Net 30 | Due in 30 days | Standard for most B2B work |
| Net 45/60 | Due in 45-60 days | Large enterprises (often non-negotiable) |
| 50% Upfront | Half before work starts | New clients, large projects |
| Milestone-based | Pay at project stages | Long projects, reduces risk |
Late Payment Fees
Consider adding late fee terms (e.g., "1.5% per month on overdue amounts"). State this clearly on every invoice. But check local laws—some jurisdictions limit what you can charge.
15%
of invoices are paid late
10-20%
faster payment with online options
3x
more likely to pay with clear due date
5Follow-Up & Getting Paid
Even perfect invoices sometimes need follow-up. Have a system in place.
Payment Follow-Up Timeline
1
Day 0: Send invoice promptly
Send immediately after work is complete or at the agreed billing date. Don't delay.
2
Day -3: Friendly reminder before due date
"Just a friendly reminder that invoice #123 is due in 3 days. Please let me know if you have any questions."
3
Day +1: Polite follow-up
"Invoice #123 was due yesterday. Please confirm payment is in process or let me know if there's an issue."
4
Day +7: Firmer reminder
"This is a second reminder. Invoice #123 is now 7 days overdue. Please arrange payment promptly to avoid late fees."
5
Day +14+: Escalation
Call the client. If no response, consider formal collection notice or pausing future work.
Keep follow-up emails professional and factual. Never get emotional. Document everything in case you need to escalate.

常见问题解答
发票上依法必须包含哪些信息？
各国要求不尽相同。一般而言，需要提供以下信息：公司名称和地址、客户名称和地址、唯一发票编号、日期、商品/服务描述、金额、税项详情（增值税/消费税）以及应付总额。具体要求请查阅当地法规。
我应该如何给我的发票编号？
使用统一的顺序格式，例如 INV-2025-001、INV-2025-002 等。格式可以包含年份、客户代码或项目代码。切勿重复或跳过数字——这对于税务和会计处理至关重要。
对于逾期未付的发票，我应该收取滞纳金吗？
滞纳金旨在鼓励及时付款，并补偿您因逾期付款而造成的现金流损失。通常的滞纳金率为每月 1-2%。请在每张发票和合同中明确说明滞纳金政策。请查阅当地法律法规，了解是否有任何限制。
我应该何时发送发票？
工作完成后或约定的结算日期应立即付款。对于持续性工作，应建立固定的结算周期（例如，每月1日）。付款延迟会导致收款延迟。
如果客户对我的发票有异议怎么办？
及时、专业地回应。仔细核对您的合同和相关文件。如果争议属实，请开具更正后的发票。如果争议不成立，请冷静解释并提供佐证材料。切勿情绪激动或采取对抗态度。
