Mistake 1: Delayed invoicing
Why it hurts: Every day you wait extends the time to cash and signals low urgency.
Fix fast:
- Invoice immediately at delivery or at predefined milestones.
- For ongoing work, switch to recurring invoices with auto‑send.
- Take deposits (e.g., 30–50%) to smooth cash flow.

Mistake 2: Incorrect or incomplete information
Why it hurts: Missing details trigger approvals to stall or get rejected.
Fix fast — must‑have fields:
- Your business + client legal names, addresses, and emails
- Invoice number, issue date, due date
- Itemized lines (description, qty/time, rate, tax)
- Currency (and whether rate is locked for international clients)
- PO/reference if the client requires one
- Totals (subtotal, tax, discounts, grand total)
- A clear “Pay Now” action

Mistake 3: Unclear payment terms
Why it hurts: Ambiguity creates excuses for delay.
Fix fast — make terms explicit:
- Due timing: Net‑0/7/15/30 (or “due upon receipt”)
- Accepted methods: card, bank transfer, wallet
- Late‑fee policy: flat fee or % per month + grace period
- Early‑pay discount: e.g., 2/10 Net‑30
- Dispute window: e.g., “Notify within 7 days”

Mistake 4: Inconsistent or unprofessional branding
Why it hurts: Sloppy layout lowers trust and invites scrutiny.
Fix fast:
- Use a single branded template (logo, colors, type).
- Keep line items clear and scannable; avoid jargon.
- Place amount due + due date prominently (top‑right works well).
- Add a polite thank‑you note and support contact.

Mistake 5: No follow‑up on overdue invoices
Why it hurts: “Silent” invoices slide to the bottom of inboxes.
Fix fast — reminder cadence that works:
- T‑3 days: friendly reminder
- On due date: quick‑pay link front and center
- +3, +7, +14 days: firmer copy referencing late‑fee policy
- Escalate: phone call → final notice → collections if needed
