2. Create an invoice with a header

When you are going to write your first consultant invoice, you need to start writing your header first. You need to create a standard header that will be constant on every invoice you create shortly. You can include the following in your header of an invoice template:

  • Your small business Logo
  • Your every business contact information, including your name, address, phone number, and email
  • Include the word “Invoice” in your header so the client can easily identify what kind of document it is.

3. Add the client’s details

Just after the header, you have to utilize the space on your invoices to fill in the client’s information as per their contact details. You need to make sure that you have included the correct point of contact in every invoice you create.

If you are dealing with a large company, it is obvious that you should have the contact details of a person who is working in the billing department. Take your time to confirm the correct billing contact person who can help you receive payments quickly for the services you have provided.

4. Include the invoice date

Add the date that you are creating the invoice below the client’s contact details. This will help both the client and you to file the invoice for bookkeeping purposes.

Your customers can use a unique invoice number in case they have any questions regarding the invoice. A consistent invoice numbering system will also help you file your invoices and keep your records organized.

The easiest way to add a numbering invoice is to do it sequentially. For example, your first invoice number can be #001, so your second invoice number can be #002 and you can follow the sequence. Some consultants create a numbering system that also includes a type of project or the client’s name.

6. List your services

Create an itemized list of all the services you have provided to the client, including:

  • A detailed description of each service
  • The number of hours worked
  • Hourly rates of pay
  • A subtotal of the charges for each service

You can organize this information into a table, using a separate column for each piece of information.

7. Include your payment terms

It is mandatory to include the payment terms and conditions on every invoice you send to the client. It will be great if you discuss your payment terms and conditions with each client before signing a contract.

So, when you send them an invoice there are no surprises. Your payments terms should also have the payment methods you accept, which can be any of the following or all of them:

  • Checks
  • Cash
  • Credit cards
  • Business bank account transfer
  • Online payments
  • Mobile payments
  • Recurring payments

The payment terms and conditions of your invoice should also include your late payment policy. If you are going to charge late fees for overdue payments, you need to include all the details of the late fees you are going to charge as a small business owner.

8. The payment due date

Include the total amount due on the invoice, along with the applicable taxes keeping in mind tax deadlines for business tax returns. Just like the accounts receivable due date, make the total due section clearly visible, with larger, colorful, and bolder fonts.

Invoicing Tips and Tricks for Consulting Services

Accounting Tips and Tricks for Consulting Services

To run a successful small business, you need to discover some really good hacks that help you avoid mistakes and improve your business process and maintain a good cash flow. Here are some valuable small business invoicing tips and tricks for consulting service management to follow:

Adjust Your Terms

You are unrestricted to adjust your payment terms and conditions for your invoices. You need to choose your payment terms according to your convenience.

It is no longer a written policy that you have to wait for 30 days to get the payment or get pain on the 20th day of the month.

Nowadays, companies causally outline a 7-day payment term, this is perfectly reasonable to keep updated accounting information.

Always be specific to your customers about your terms in advance before creating an invoice or even before you sign a contract with them.

It is ideal to state your expectations such as due dates, late fees, business credit, extra business expenses, payment methods, and what happens if the payment deadlines don’t match.

You may also require advance payment or deposit income to start the work or the client might need to split the payments. It will be good if you adjust your payment terms in advance before giving any kind of commitments to manage extra business expenses and finances.

Follow-up Overdue Invoices

When it comes to getting paid for the work you have delivered, you need to let go of the awkward feeling about asking for money to manage cash flow.

In many cases, when companies take follow-ups they have discovered that the client has simply forgotten to pay, never received the payment due to a change of address, and/or misplaced the invoice due to poor financial management.

It clearly indicates that the clients’ intentions were not like what the companies were thinking. The customers feel awkward sometimes that they have forgotten to pay. One of the important invoicing tips for small businesses is that it will be easier if you gently talk to the client over the phone, just ask about their well-being first, and then ask about the reason for not paying on time.

If you don’t find it genuine then you can take the help of a debt collector at the last stage – but do not leave it easily.

Value-Added Services

First of all, you need to stop feeling guilty about charging for the time you are investing in a client.

You need to trust your value-added services and feel confident with your pricing whenever you are sending an invoice to the client. When you value your time and efforts only then the client will be able to understand your point of view.

Invoice As Soon As Possible

You do not have to wait till the end of the month to send your invoices; rather, you can just send them off as soon as you complete the project.

Make It to Get Paid

Moreover, it should also state the payment instruction, terms, and conditions. This helps and guides the customers to pay you promptly without any confusion.

Open a Business Bank Account

Keeping a separate bank account for business and personal expenses is immensely helpful during the tax season.
