  • Accept online payments

    Get paid quickly by allowing your clients to pay your invoices online. Your clients can use any major credit or debit card with just the click of a button.

  • Scheduled auto-sending New!

    You've created an invoice, but you're not quite ready to send it yet? No problem. Harpoon allows you to select a future date and will automatically send the invoice for you at that time.

  • Customize your invoices New!

    Harpoon's invoices are clean and beautiful to begin with, and even more so when you add your own logo, branding color, accent image, font style, etc.

  • Quick invoice creation

    You shouldn't need to jump through multiple screens just to build an invoice. Invoice creation in Harpoon couldn't be easier. Just a few clicks and you're done.

    Set up custom payment terms for your invoices and have Harpoon automatically send late payment email reminders to your clients. It's one less thing you need to think about.

  • Percentage & fixed discounts New!

    Your invoices can include a percentage based discount that's applied to the entire invoice, or fixed amount line item discounts for tighter control of the amount when needed.

  • Custom due dates New!

    Payment terms for an invoice can be set using relative time frames (e.g. 30 days) or you can manually select a specific future date the invoice is due.

  • Get notified of a viewed invoice

    Ever wondered if a client has even viewed your invoice yet? With Harpoon, wonder no more. You'll know exactly when your clients open and view their invoices.

  • Recurring invoices

    Harpoon keeps track of a project's fixed fee budget and helps you invoice the accurate remaining amount of that budget, even if it's a repeating budget. Accidental over or under billing is a thing of the past.

  • Create custom hourly rates

    Do you charge differently for design work compared to administrative work? No sweat. Harpoon allows you to create custom hourly rates for each of your time-tracking task categories.

  • Custom rates per client

    Sometimes the same rate doesn't fit for all of your clients. With Harpoon you can not only customize your hourly rates on a per task basis, but also on a per client basis. We're flexible like that.

  • Custom rates per project New!

    In addition to custom hourly rates per task category and per client, with Harpoon you also have the flexibility of setting custom rates for each of a client's projects, just in case you need it.

  • Per invoice overrides New!

    You can override your global default settings like contact information, late payment reminders, online payments, etc. on a per invoice basis.

  • Create, send, & manage estimates

    Typically sent to your clients before you do the actual work, estimates are a simple way for your clients to approve the basic scope and costs of smaller projects.

  • Invoice in multiple languages

    Create invoices in your clients' native languages, including English, Spanish, French, German, Greek, Dutch, Italian, and more ¡Hurra!

  • Download as a PDF

    You can conveniently manage and send invoices to your clients directly within Harpoon. But for those times when you need an offline copy of an invoice a PDF download is always available.

  • Organize and filter

    Harpoon provides a handful of filtering tools that allow you to track the status of your invoices. Know which invoices have been sent, viewed, paid, or even partially paid; which are still drafts, and which are overdue.

    Besides viewing and paying your invoices online, you also have the option of including a PDF attachment of the invoice when sending it to your client.

    You have the ability to show or hide the Quantity and Unit Price columns on your invoice line items on a per invoice basis. Handy when billing for fixed fee amounts.

    You can create as many tax types as you need (including VAT, GST, PST, HST, etc.) and apply any combination of taxes on a per line item basis on your invoices.

  • Custom invoice titles New!

    "Invoice" or "Estimate" aren't exactly the titles you want displayed to your clients? No problem. You can customize your invoice or estimate titles to whatever you need them to be.

    View a timeline of all the important activities surrounding an invoice, along with the dates those activities took place, conveniently packaged in a single view for historical reference.
