Step 1: Create a new invoice

Create an invoice quickly from your homebase focus using the icon under "Add new." You can also make an invoice using the 3 dots that appear on hover next to your client's name in the left panel.

Find a list of invoices in accounting > invoices. You can create a new invoice from this tab using the button in the upper right corner.

Step 2: Connect your invoice with a client

All activities in Hectic™ centralize around the client (unlike other apps, which centralize around the task). This is because we know your freelance business revolves around your clients and that you need a seamless, client-centered app experience.

Select or create a new client to invoice.

Choose "Standard" for a regular invoice. Choose "Deposit" to request a deposit from a client. Deposits can be credited to future standard invoices. You can also choose to create a recurring invoice.

If you choose to create a new client at this stage, it will begin a client file. Only the client name is required to continue. We recommend completing as much of the form as you can since it will auto populate in other needed areas of the site, including your invoices.

Step 3: Add billable items

Invoices integrate directly with project management, time tracking, and expenses. You can also keep a product and services library that is easy to add to any invoice.

Add a new line item

When you click "Add new line item" you will see your product and service library. Set up products or services that you bill for often without necessarily associating them with a project. You determine the rate and units (or hourly rate). Click any product or service to add it to your invoice then enter the quantity and Hectic's invoice will do the calculation for you.

If you are adding a net new item, choose "Create new" to set it up. This item will be automatically saved for future use. Edit or delete items in your product and service library by using the edit pencil or trash can icons.

Add hours or billable project
If you have been using time tracker and project management, you can select "Add hours or billable project" and all of the un-billed stuff will show up for you to easily add to your invoice. Any un-billed retainers, time tracked (sorted by month and week), flat rate projects, or per item tasks that are completed* can be added at this point.

*Per item tasks can only be added to your invoice when they are in the column you designated as your completed column, or to the right of that column on your kanban board.

Add reimbursable expense

If you have an expense that you have marked as reimbursable and assigned it to this client, you will also see a line that says "Add reimbursable expense." Click it to quickly add your expenses to the invoice.

Apply deposit credit

If you collected a deposit from your client (which we highly recommend, especially if it is a new client), you will see a link to apply the deposit credit to an invoice before you send it. You can click this button to see the deposit collected, deposit available, and choose how much of the deposit to apply to this invoice.

Use the "Tax" checkbox for any line items that are taxable. Be sure to add the percentage tax amount just above the total due.

Q: When do I include tax?

A: In the US, almost never. Most states allow merchants to charge sales tax for goods but not services. However, some states allow sales tax for services, especially if these services accompany a good. For example, Delaware, Hawaii, New Mexico, and South Dakota tax most services. So be sure to consult with an expert on whether you can charge sales tax for your services, even if you live in these states.

Step 4: Add payment instructions and terms

At the bottom of your invoice, you can add notes to your client, payment instructions, attachments, and payment terms.

Payment instructions
Here are some ideas to include in your payment instructions.

  • Accepted payment types (Stripe, PayPal, ACH, check, direct deposit, credit card, cash, etc.)

  • Any additional fees with any of these payment methods

  • Where the client can go for questions or direct deposit information

Example payment instructions blurb:

Accepted forms of payment include check, direct deposit, and Stripe (additional fees may apply). Cash payments are accepted in person only. Please make checks payable to eFreelancer, LLC. For questions concerning this invoice, or to set up direct deposit, please contact Erica Harrison, (719) 637-8373 or

Payment terms

Payment terms represent the timeframe within which the client must pay your invoice. You want to structure your payment terms in a way that fosters a positive client relationship. Payment terms will populate automatically based on what you set up with this particular client.

Set your payment terms from your client overview screen when you click on edit and then the "Invoicing & payment settings" tab.

Late payment fee

Charging late fees is best practice in freelancing because it leads to a higher percentage of paid invoices and shows you take yourself and your work seriously.

In Hectic's invoicing system, late fees are calculated daily. If your client pays 1 day late, the fee is smaller than 2 days late, etc. It's calculated at the time they view the invoice. A late fee is not applied in one lump sum.

Typically, late fee charges for unpaid invoices fall between 1.5% and 3% interest per month after the payment due date. These percentages seem small, but they're mighty; they serve as written (and legal) incentives for clients to pay on time.

Make sure any late fee conditions you include within your payment terms are per usury state laws. Familiarize yourself with the maximum annual interest rate in your state and consult a professional if you have questions.


The standard invoicing payment timeframe is 30-days. But keep several things in mind when configuring this section:

  • Is it a milestone payment? We suggest 'On Receipt' because it's recommended you do not start work on the second milestone until the payment goes through.

  • Is it a new client? Give new clients a more standard experience (30 days). As your professional relationship progresses, it will become possible to have the conversation of whether this timeframe can be improved to meet the needs of both parties better.

  • Is it a retainer? If so, it makes sense to choose one of the longer time frames.

Pass credit card fees onto client?

Hectic™ gives you the ability to either pay the credit card fees yourself, pass them onto the client, or split them with the client.

Before passing them onto the client, keep in mind that these fees can usually be considered tax-deductible for you as a freelancer, but be sure to consult with a tax professional for verification.


For longer projects, determining the invoicing schedule by establishing payment milestones with the client before starting work to guarantee payments over the course of the project. Milestones also improve communication with clients and build that vital, healthy client relationship.

In Hectic™, a "milestone" translates into a "task." So, as you finish the task(i.e., milestone), you can bill for it via an invoice. This is why creating proposals before a project starts is so important; it allows you to establish payment milestones (i.e., tasks) before you start work.

Step 5: Email or download the invoice

When you click the blue "Share" button in the top right corner, you will see two ways to get the invoice to your customer:

  1. Hectic email: The app will send the invoice to your contact(s) with a personalized message from you.

  2. Download PDF: Save the invoice as a PDF and send it your own way.

Freelance Industry Best Practices: Invoicing

  • Require a deposit

  • Establish milestone payments for longer projects

  • Don’t agree to terms state you get pain only upon the full delivery of the work.

  • Get it all in writing with a contract

  • Establish your own standardized billing cycle that is frequent and predictable. This signals that you value your time and your work.

  • Bill early and often, despite the client's payment schedule.

  • Obtain the name and contact details of the person cutting the check. This way, if there are delays, you have someone to call.

  • Be vigilant. Don't hesitate to be persistent about seeking payment. This is another way to show that your time and work is valuable, and should be compensated accordingly.

It's also recommended to obtain the payment schedules and policies for each client before you do any work. Here are some questions you can ask your client:

  • How does their fiscal year run?

  • How long does it typically take to process invoices?

  • Which day(s) of the week do they cut checks?

  • How do they pay contract workers?

Regardless of your client's processes, it's important that you establish your own standardized billing cycle that is frequent and predictable. This signals to the client that you value your time and your work. You can then collaborate with the client to agree upon (in writing with signatures) the most productive methods of invoicing for your particular business relationship based on mutual needs and procedures.
