Top 15 Business-to-Customer English Mistakes (and How to Fix Them)
You’ve probably made one of these Business English Mistakes today, maybe even without realizing it.
That “quick” email you sent to a client? The one that said, “Kindly revert back soon” or “Please do the needful”? Yeah… that’s one of them.
Welcome to the world where your English doesn’t just communicate, it represents your brand.
Because in global business, a single awkward phrase can make you sound either professional or painfully outdated.
So let’s fix that. These are the 15 most common Business English Mistakes, and how to fix them fast, without sounding like a grammar textbook or a chat-bot.
1. “Kindly Revert Back”
You meant: “Please reply soon.”
Why it’s wrong: Revert already means “reply.” Adding back is redundant.
✅ Fix: “Please reply at your earliest convenience.”
Tip: Polite doesn’t mean robotic. Try “Looking forward to your response” for a warmer tone.
2. “Please Do the Needful”
This one’s an international classic, and one of the most recognizable Business English mistakes in the world.
✅ Fix: “Please take the necessary steps.”
Modern business English values clarity over formality. Think clear, short, friendly.
3. “Myself Will Send the Report”
You’re not alone, many professionals mix this up trying to sound formal.
✅ Fix: “I will send the report.”
Myself is only for emphasis: “I’ll do it myself.”
4. “I Am Out of Station”
Unless you’re literally at a train station, skip this phrase.
✅ Fix: “I’m out of town” or “I’m traveling this week.”
This small correction instantly makes your communication sound more natural and global.
5. “We Are Doing the Needful”
This is another variation of outdated corporate English.
✅ Fix: “We’re taking care of it.” or “We’re handling that now.”
Modern companies prefer conversational tone over stiff formality.
6. “I’m Having Some Doubts”
In many languages, doubt means “question.” But in English, it means “lack of trust.”
✅ Fix: “I have some questions.”
This is one of the Business English mistakes that can completely change meaning, and tone.
7. “We Will Inform You Soon”
It sounds robotic, right?
✅ Fix: “We’ll let you know soon.” or “We’ll get back to you shortly.”
A touch of natural rhythm goes a long way in business writing.
8. “Each and Every Employee Must…”
Overly formal and repetitive.
✅ Fix: “Every employee must…”
Keep it clean, confident, and simple. Simplicity communicates authority.
9. “Please Find Attached the File”
You don’t need to “find” it, it’s right there.
✅ Fix: “I’ve attached the file for your review.”
Bonus: “Here’s the file you requested” sounds friendly and human.
10. “We Regret to Inform You…”
This phrase isn’t wrong, just emotionally outdated.
✅ Fix: “Unfortunately, we have to let you know…”
It’s more empathetic and conversational while staying professional.
11. “We Are Planning to Do a Meeting”
✅ Fix: “We’re planning a meeting.” or “We’re going to have a meeting.”
Using do here is one of those sneaky Business English mistakes that make your English sound translated.
12. “I Am Agree”
✅ Fix: “I agree.”
Super short. Super correct. Super powerful.
13. “We Discussed About the Project”
✅ Fix: “We discussed the project.”
The preposition about doesn’t belong here. You can either “discuss” something or “talk about” it, never both.
14. “Let’s Discuss About the Future Plan”
✅ Fix: “Let’s discuss the future plan.”
Yes, it’s similar to the last one, but it’s so common it deserves its own spot on the Business English mistakes list.
15. “I Look Forward to Hear from You”
✅ Fix: “I look forward to hearing from you.”
Gerunds (the -ing forms) matter in formal writing. This one’s small, but clients notice.

Here’s the thing: fixing Business English mistakes isn’t just about grammar.
It’s about tone, confidence, and clarity.
Let’s upgrade your communication style with 5 modern fixes:
1. Drop the Over-Formality
Old-school business English sounds cold and distant. Instead of:
❌ “I would like to request you to kindly confirm.”
✅ Try: “Could you please confirm?”
It’s shorter, friendlier, and more natural.
2. Use Action-Oriented Words
Replace stiff verbs with dynamic ones:
- “Do an analysis” → “Analyze”
- “Give your feedback” → “Share your feedback”
This makes your writing sound confident and modern.
3. Avoid “Per” Phrases
❌ “As per your request”
✅ “According to your request” or “As you requested”
You sound like a real person, not a 90s fax machine.
4. Use Positive Language
Instead of saying what can’t happen, emphasize what can.
❌ “We can’t ship it this week.”
✅ “We’ll ship it early next week.”
This subtle shift makes your brand sound reliable and proactive.
5. Let AI Help (But Don’t Let It Speak for You)
Yes, AI tools can catch Business English mistakes before you hit “Send.”
But always re-read your message aloud.
If it doesn’t sound like you, tweak it.
AI is your co-pilot, not your voice.
Why These Business English Mistakes Cost You More Than You Think
Every email, every chat, every LinkedIn post you write builds your personal brand.
When your English feels natural, people trust you faster.
When it feels stiff or “translated,” they hesitate — even subconsciously.
You might have the best product, idea, or proposal in the world.
But if your language creates distance, your reader disconnects.
Fixing Business English mistakes isn’t about perfection.
It’s about connection.
