How to Write a Receipt: Complete Guide for Small Business Owners

How to Write a Receipt: Complete Guide for Small Business Owners

Introduction

Most small business owners don't think twice about receipts. They're the little slips of paper you hand over after a transaction — or the digital confirmation that flashes on a screen after someone taps their card.

But receipts are far more than transaction confirmations. For freelancers, contractors, and small business owners, a properly written receipt is a legal document, a bookkeeping essential, and your first line of defense in any payment dispute.

This guide covers everything you need to know about writing professional receipts: the required fields, common mistakes, legal requirements, digital alternatives, and how to generate receipts in under 30 seconds with free tools.

By the end, you'll understand exactly what makes a receipt hold up under IRS scrutiny, satisfy your accountant, and protect your business.

What Is a Receipt and What Does It Do?

A receipt is a written acknowledgment that a payment has been received. It documents the transfer of money from a buyer to a seller in exchange for goods or services.

Unlike an invoice (which requests payment), a receipt confirms that payment has already been made. It serves several critical purposes:

• Proof of transaction: Establishes that a purchase occurred
• Legal protection: Documents payment in case of disputes
• Tax compliance: Required by the IRS for business expense deductions
• Bookkeeping: Forms the foundation of accurate financial records
• Customer service: Gives buyers confidence their payment was processed

If you accept payments — whether from clients, customers, or customers — you need to provide receipts. It's that simple.

Receipt vs. Invoice: What's the Difference?

This is the most common point of confusion for new business owners. Here's the direct comparison:

| | Receipt | Invoice |

|---|---|---|

| When issued | After payment is received | Before payment is due |

| Purpose | Proof of completed payment | Request for payment |

| Who issues it | Seller (to buyer) | Seller (to buyer) |

| What it shows | Amount paid, items purchased | Amount owed, payment due date |

| Legal significance | Confirms transaction complete | Establishes debt |

| Used by | Retailers, service providers, freelancers | Freelancers, B2B service providers |

Example: You hire a web developer to build your site. She sends you an invoice for $3,000. You pay it. She then sends you a receipt confirming the $3,000 was received.

You'd use an invoice if you're the one billing a client. You'd use a receipt if you need to prove payment was made (as either the buyer or seller).

Who Needs to Issue Receipts?

If you run any kind of business that accepts payment, you need to issue receipts. This includes:

• Freelancers and contractors receiving payment from clients
• Service-based businesses (photographers, designers, consultants, tutors)
• Retail businesses selling products
• Online businesses processing digital payments
• Any business required to collect sales tax

Even if a client says they don't need a receipt, you should always provide one. The receipt protects you as much as it protects them. The SBA's guide to starting a small business recommends keeping complete financial records — including receipts for all transactions — as a foundational habit from day one.

The 6 Mandatory Fields Every Receipt Must Have

A receipt isn't valid — or useful — without these core elements. Here's what to include every single time:

1. Your Business Information

Your receipt must clearly identify your business:

• Business name (or your full name if sole proprietor)
• Business address
• Phone number or email
• Tax ID / EIN (if applicable in your jurisdiction)

This establishes who received the payment.

2. Customer Information

Who made the payment:

• Customer's name
• Customer's address (for larger transactions)
• Customer's email (optional but helpful for digital receipts)

3. Payment Date

The exact date payment was received. This is critical for:

• Tax year attribution
• Bookkeeping accuracy
• Dispute resolution

Always use a full date format: March 26, 2026 or 2026-03-26.

4. Description of Goods or Services

What was purchased or provided:

• Itemized list of products or services
• Quantities where applicable
• Brief description sufficient to identify the transaction

Bad example: "Services"

Good example: "Logo design package — 3 initial concepts + 2 rounds of revisions"

5. Amount Received

The exact amount paid:

• Subtotal (before tax)
• Tax amount and rate
• Total amount received
• Payment method used (cash, card, check, bank transfer)

For international transactions, clearly state the currency.

6. Unique Receipt Number

A unique identifier for each receipt, which allows you to:

• Track all transactions
• Reference specific receipts in disputes
• Reconcile with bank statements

Format options:

• Sequential: RCP-001, RCP-002
• Date + sequential: 2026-03-26-001
• Transaction ID (for digital payments)

Optional But Recommended Fields

These aren't mandatory, but they make your receipts more professional and useful:

Payment Method

Knowing whether payment came via cash, credit card, PayPal, or bank transfer matters for your records. Note it on the receipt.

Reference Number (For Card/Online Payments)

If paying by card, include the last four digits of the card or the transaction ID from your payment processor. This links the receipt to the actual payment in your processor's records.

Terms and Conditions

For larger transactions, a brief statement of your refund or service policy can prevent disputes.

Your Signature

For formal or high-value transactions, a signature adds legitimacy. For everyday retail receipts, it's optional.

Digital Receipts vs. Paper Receipts

Paper Receipts

Pros:

• Immediate for in-person transactions
• No technology required
• Some clients still prefer paper

Cons:

• Can be lost, damaged, faded
• Hard to organize and search
• Environmentally wasteful
• Difficult to reconcile with bank statements

Digital Receipts

Pros:

• Instantly emailed or texted to customer
• Cannot be lost or damaged
• Easily searchable
• Automatically organized
• Eco-friendly
• Easier for tax preparation

Cons:

• Requires email or phone number from customer
• Some customers ignore digital receipts
• Need reliable internet connection

Best practice: Offer both. Hand over a paper copy for in-person transactions, and immediately send a digital copy via email. Eonebill does this automatically when you create a receipt.

Common Receipt Mistakes That Cost You

These errors show up in audits, cause disputes, and create bookkeeping nightmares:

Mistake 1: Missing the Date

This is shockingly common. Without a date, you can't prove when a transaction occurred. Always include the full date.

Mistake 2: No Description of Goods or Services

"Payment received" tells no one anything useful. Be specific. "Two hours of business consulting — March 2026" is clear. "Consulting" is not.

Mistake 3: Wrong Amount

Always verify the amount before printing. A receipt showing the wrong total undermines your credibility and creates accounting problems.

Mistake 4: No Receipt Number

Without sequential numbering, you can't track all receipts or prove you issued one if challenged. Always assign a unique number.

Mistake 5: Forgetting Tax Information

If you're collecting sales tax or VAT, the receipt must show the tax rate and amount separately. This is required for customers to claim input tax credits.

Mistake 6: Not Issuing a Receipt at All

This is the biggest mistake. Every payment you receive should produce a receipt — even if the customer says they don't need one. It protects you in disputes and is essential for your tax records.

Mistake 7: Poor Record Keeping

Issuing receipts is only half the battle. You need to store copies of every receipt you issue, organized by date, for at least 7 years (IRS requirement for business records).

How Long Must You Keep Receipts?

The IRS requires businesses to keep records for at least 3 years from the date the return is filed, or 7 years if income is underreported by more than 25% (IRS Publication 583 — Starting a Business and Keeping Records). For state tax purposes, requirements vary by state.

For practical purposes:

• Keep digital copies: Scan paper receipts immediately and store in cloud storage
• Use a bookkeeping system: Link receipts to transactions in QuickBooks, Wave, or Eonebill
• Organize by year: Create folders for each tax year and subfolders by month

Pro tip: Take a photo of every paper receipt immediately. Paper receipts fade over time — especially thermal paper. The IRS has accepted photos of receipts for years.

Receipts for Cash Payments: Special Considerations

Cash transactions deserve extra attention because they're harder to verify after the fact.

Beyond the standard fields, cash receipts should include:

• Payment method clearly marked as "Cash"
• The full amount in both numbers and words (for large amounts)
• A note on whether change was given
• Any cash-handling employee name

The IRS specifically scrutinizes cash businesses. Without proper documentation, you have no proof of income. A well-written cash receipt is your evidence that the money was received and reported.

Keeping Cash Safe

If you regularly accept cash:

• Issue a receipt immediately upon receiving payment
• Reconcile cash on hand daily against receipt records
• Use a point-of-sale system that tracks all transactions
• Never skip issuing a receipt because the amount is small

Receipts for Freelancers: What You Need to Know

As a freelancer, you issue receipts when you receive payment from clients. Here's what to keep in mind:

Always Issue a Receipt Upon Payment

When a client pays your invoice, immediately send a receipt. This:

• Confirms the payment was received
• Provides the client with their proof of payment
• Creates a paper trail for your records
• Closes the loop on the billing cycle

Link Receipts to Invoices

Every receipt should reference the corresponding invoice number. This creates a clear audit trail:

Receipt #RCP-2026-001
Payment received from: Acme Corp
For invoice: INV-2026-0042
Amount: $1,500.00
Payment method: Bank transfer
Date: March 26, 2026

For Partial Payments

If a client pays in installments, issue a separate receipt for each payment and note the remaining balance.

For Retainers

If a client pays a retainer fee, issue a receipt showing:

• Retainer amount paid
• The service period it covers
• Any refund policy if unused

How to Generate Receipts on Your Phone

Best Practices for Professional Receipts

Make Them Legible

Use clear fonts, adequate spacing, and professional formatting. A receipt that's hard to read looks unprofessional and is harder to use for bookkeeping.

Be Consistent

Use the same receipt format every time. Inconsistency signals sloppiness and makes reconciliation harder.

Keep Copies

Every receipt you issue should be stored in your records. Eonebill automatically saves all receipts to your account.

Use Professional Language

Even simple receipts should use professional language:

• "Payment received for" instead of "Got paid for"
• "Professional services rendered" instead of "Work done"
• Full dates and proper spelling

Include Contact Information

Give customers a way to reach you if they have questions about the receipt. Include your email and phone number.
