Getting invoice timing right is an integral part of a business’s cash flow management and customer experience. A well-timed invoice can mean the difference between a healthy cash flow and an unexpected financial tight spot, between an effortless customer experience and one that’s plagued by undue friction.

Invoice timing is connected to a variety of factors, such as the nature of your business, the terms of your contract, and your relationship with the client. It’s a balancing act between ensuring your company’s cash flow remains robust and maintaining good client relationships by not seeming overeager to collect payments. Knowing when to send an invoice plays a core role in striking this balance. Below are key considerations and strategies for timing your invoices effectively, based on what type of business you run and how you work with your customers.

What is an invoice?

An invoice is a document that a seller issues to a buyer outlining the goods or services provided, the quantities, the agreed prices for these items, and the total amount that the buyer owes. It serves as a bill or a claim for payment, enabling a seller to ask the buyer to fulfill their obligation. The invoice also includes the date of issue, a unique identifier or invoice number, and the contact information of both parties.

Beyond acting as a request for payment, an invoice serves as a record of sale for both parties and can be used for financial recordkeeping, tax purposes, and, potentially, as a legal document in the event of a payment dispute.

What are invoices used for?

Invoices serve several important functions in business transactions:

• Request for payment
  An invoice’s primary purpose is to request payment from a buyer for goods or services rendered and to detail the amount due.

• Record of sale
  Invoices serve as a record of the transaction between a seller and a buyer. They document what was sold, how much was sold, and at what price. This can be particularly helpful in tracking sales, analyzing business performance, and making informed business decisions.

• Legal protection
  If there’s a dispute over payment or the details of a transaction, an invoice acts as a legal record. It clarifies the terms agreed upon by the buyer and seller, providing protection to both parties.

• Financial management and accounting
  Invoices are important for maintaining accurate financial records. They help track revenue and are integral for budgeting, forecasting, and financial reporting.

• Tax preparation
  Invoices serve as evidence of income, making them essential for calculating taxes. They can also provide a record of tax collected from sales (like sales tax or VAT) within jurisdictions and tax regulations that allow it.

• Audit trail
  In case of financial audits, invoices serve as evidence of business transactions, ensuring compliance with tax laws and business regulations.

Customer invoices: When should you send them?

Understanding when to send an invoice is important to maintaining a healthy cash flow for your business. The timing depends largely on the nature of your business, the terms agreed upon with your customer, and the type of invoice you are using. Here are a few common scenarios:

1. Service-based businesses
For service-based businesses such as consulting firms, marketing agencies, and freelancers, invoicing often occurs after the services have been delivered. This is referred to as “invoicing in arrears.” For example, a freelance graphic designer may complete a project and then issue an invoice detailing the hours worked and the agreed-upon rate.

In some cases, service providers invoice periodically, such as monthly or quarterly, especially for ongoing services. A digital marketing agency, for instance, could send a monthly invoice to their clients for continuous SEO services.

2. Product-based businesses
Businesses that sell physical products often send an invoice at the point of sale. For instance, a retailer would issue an invoice immediately after a customer purchases items from their store.

In ecommerce, a business sends an invoice once the customer has confirmed the order, and the invoice often accompanies the shipped goods. For example, an online clothing retailer would send an invoice as soon as a customer’s order is processed, detailing the items purchased and the total cost.

3. Progress billing
For large-scale projects, such as construction or bespoke software development, businesses often use progress billing, where invoices are issued at various stages of the project. These stages could correlate to when certain milestones are met or when a specific percentage of the work is completed. For instance, a construction company might invoice after the completion of each project phase: foundation, framing, roofing, etc.

4. Recurring billing
For businesses providing subscription-based services, such as SaaS products or a magazine subscription, invoices are usually sent at regular intervals—monthly, quarterly, or annually—as per the subscription agreement.

5. Up-front payment
In certain cases, businesses may require payment in advance, especially when there’s a significant outlay for materials or when the customer’s credit is uncertain. In this case, the invoice is sent before the business delivers the product or performs the service. For instance, a custom furniture manufacturer might require a 50% payment up front to cover material costs, and they would send the customer an invoice detailing this advance payment.

6. Retainer model
In the retainer model, which is often used by law or public relations firms, clients pay a set amount regularly (usually monthly). The firm provides an invoice detailing how the retainer was used—for instance, how many hours worked, and on which projects—and any extra charges beyond the retainer.

In short, the timing for sending customer invoices depends greatly on your specific business model, the nature of the goods or services you provide, and the agreement with your clients. Regardless of when you send your invoices, remember to be clear on your payment terms, prompt with your invoicing, and consistent in your follow-up to ensure timely payments.

Best practices—and mistakes—when sending invoices

A well-managed invoicing process is essential for the financial health of any business. To optimize this process, let’s take a look at some best practices and common mistakes around invoicing procedures:

Best practices for invoicing

• Give clear and detailed information
  Always ensure that your invoices contain all necessary information, such as contact details of both parties, a unique invoice number, the date, a detailed list of products or services provided, the total amount due, and payment terms. The more specific and clear the information, the less room there is for confusion or dispute.

• Use professional invoice templates
  Using a professionally designed invoice template can enhance your business’s image, ensure you include all the necessary information, and help maintain consistency.

• Establish clear payment terms
  Be clear about your payment terms. Include due dates, acceptable payment methods, and details about any late fees or early payment discounts.

• Prompt invoicing
  Send out invoices promptly after the completion of a sale or service. Timely invoicing helps enable timely payments.

• Regular follow-ups
  Following up—politely—on unpaid invoices is key. Develop a system for reminders that escalates from gentle nudges to more formal notices as necessary.

• Embrace technology
  Consider using digital invoicing software. These tools can automate many aspects of the invoicing process, including sending out invoices, reminding customers about upcoming and past due payments, and keeping track of your cash flow.

Common mistakes to avoid

• Procrastination
  Delaying the invoicing process can lead to delayed payments, which can negatively affect your cash flow. Aim to send the invoice as soon as the product or service is delivered.

• Ignoring partial payments
  If a customer has made a partial payment, it’s essential to send an updated invoice showing the remaining balance. This ensures clarity about what the customer still owes.

• Inconsistent invoicing
  Inconsistencies in invoice design, information, or timing can create confusion. Ensure you use a standard template and have a regular invoicing schedule.

• Overlooking errors
  Double-check your invoices for mistakes in quantities, prices, or calculations before sending them. Errors can lead to disputes or delayed payments.

• No follow-up plan
  Businesses often focus on creating and sending invoices but forget to strategize about following up on payments. Establish a system for follow-ups and dealing with late payments.

Paying attention to these best practices and common pitfalls can help businesses create an effective and efficient invoicing process, which in turn contributes to a better, more reliable cash flow, fewer payment disputes, and less unnecessary time spent chasing payments.
