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.
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.
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.
Does your business generate revenue from sources outside of invoice payments? With Harpoon's Other Income feature you can easily track unlimited sources of income so that your agency's overall revenue metrics are always accurate.
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.
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.
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.
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.
Schedule your invoices to be automatically created and (optionally) sent to your clients at set intervals. Collect payments online and keep your business running even while you sleep.
Have a one-off invoice or estimate you'd like to use for different clients and projects? A single click allows you to duplicate (and customize) any existing invoice or estimate.
Format your invoice and estimate line items and notes with the flexibility of a word processor. Bold, italics, line breaks, links, etc., all at your fingertips.
Automatically charge your client’s credit or debit card (or via ACH) for recurring invoices. Perfect for subscriptions, ongoing retainer fees, or any kind of repeating service or product fees you might offer your clients.
We proudly support customers based in countries from around the globe. From dollars to pounds, euros to krones, your Harpoon account will feel right at home wherever you do business.
Based on your active recurring invoices Harpoon provides an estimate of your average active monthly and yearly recurring revenue. Understand the true value of your retainers and other recurring services.
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.
Everyone appreciates a thank you, and so will your clients. As a professional touch Harpoon will automatically send a custom thank you confirmation to your clients on your behalf.
Tracking your time in Harpoon is a cinch, and it's just as easy to transfer those recorded hours to an invoice. Harpoon then keeps track of which hours still need to be billed.
When adding recorded hours to an invoice you'll have powerful date, task, team, and search filters at your fingertips to help find the exact time entries you're looking for.
Easily track and record project expenses in Harpoon, and then transfer those expenses to an invoice. You'll always know which expenses have been billed and which still need to be reimbursed.
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.
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.
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.
You can override your global default settings like contact information, late payment reminders, online payments, etc. on a per invoice basis.
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.
Create invoices in your clients' native languages, including English, Spanish, French, German, Greek, Dutch, Italian, and more ¡Hurra!
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.
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.
When adding recorded hours to an invoice you have the option of grouping entries by task category, by date, by team member, or as separate line items.
Add a personal note to an invoice to grab your client's attention with important information. Or add a subject line to an invoice to summarize what the invoice is all about.
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.
"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.
Manage overpayments or otherwise money "owed" back to your clients. Apply credit to new or existing invoices as Harpoon automatically tracks credit balances for your clients.
Give your clients easy access to view and manage their billing status and account history with online Account Summary Statements. Just one more way to help you get paid in full and on time.
Harpoon displays the total amount of revenue represented by your sent estimates and compares it to the revenue represented by estimates that were actually accepted by your clients.
Collect and view the details of your invoices over time in a single document. Break your reports down by client, projects, or status. Share and distribute your reports in common formats.
Get notified via email and Slack when a client has viewed an invoice or estimate, when a late payment reminder has been sent, when an estimate has been accepted, and when a payment has been received.
Harpoon calculates how many days (on average) it takes each of your clients to make a full payment on their invoices. This can come in handy when trying to predict cashflow timing.
Save time by using an existing invoice to create a new recurring invoice template. Select your date range, frequency, and delivery method and you're good to go. Automation for the win!
Each line item on your invoices and estimates can be assigned an item category (e.g. Hours, Deposit, Fee, etc.) and you have the freedom to customize these categories to best fit the services your business provides.
Insert dynamic date variables into your recurring invoice templates to automatically display the current month/year within your invoice line items, subjects, and notes fields.
