Our goal is to give you complete transparency into your fulfillment. That includes how much you're paying us, and what for. Your billing page is a real-time record of the work we're doing and how much we're charging you for it.

Accepted Payment Methods

Whiplash accepts Visa, MasterCard, American Express, and ACH. To set up ACH, contact support—otherwise, add a card by clicking the button in the "General" tab of your Preferences.

Credit Card vs ACH

The primary difference between these two methods is the way we handle payment processing fees.

Credit Card Customers

Whiplash is a prepaid service. You will pre-pay for about a week's worth activity based on the past 3 weeks' volume. That balance will be spent down as your orders ship. When your balance reaches zero, we'll charge your card for the next week's activity plus any negative balance.

You can have us set a custom refill amount for your account instead of a flexible per-week charge, which will be charged when your account balance reaches zero.

ACH Customers 

ACH is billed similar to credit card payments. However,  ACH charges are run once per week. You will be charged a refill amount for about a week's worth of activity in addition to any negative balance due at the time your ACH account is billed. If your account is still positive once we are running ACH charges the following week, you will be charged your refill amount less the remaining balance. ACH payments take seven days from the time they are run to clear into your Whiplash account. 

Please note: As a prepaid service, you must keep a billable account on file at all times. If at any time your ACH debit is declined by your bank, your account will be placed on a payment hold and a credit card must be added to your account to resume service. 

Invoicing & Statements

Whiplash is prepaid so we don't issue invoices, but we create reports at the end of each month which you can use for record keeping and a full accounting of a month's charges. These can be exported from your billing page.


Storage fees are applied on the first of the month to cover the previous month's activity. The amount is based on what you have in stock at the end of the month. So if you receive your product on the 15th and ship it all before the 1st, you beat the system!

If your actual storage charges are less than the minimum storage fee, a second fee is added to make up the difference. We list the two fees separately so you can see how much "free" storage you have left vs. the actual storage you're using.

Multiple Currencies

If you're using Whiplash in multiple currencies, you'll see a set of tabs that shows your balance in each currency. Each of these currency accounts will be kept topped-up for the upcoming week's activity.

At the end of each month, you'll get a statement for each currency you do business in.

Whiplash UK billing is in British Pounds, Sterling. Whiplash Canada billing is in Canadian Dollars.
