What Is FastSpring and Why Does Ahrefs Use It?

FastSpring is a premier digital e-commerce platform and Merchant of Record (MoR) based in Santa Barbara, California, and Amsterdam, Netherlands.

When software companies expand globally, complying with regional tax laws - such as European Union VAT, UK VAT, Indian GST, Canadian GST/HST, and US state sales taxes - becomes an accounting nightmare.

Instead of managing local tax registrations across 200+ countries, Ahrefs delegates financial checkout operations to FastSpring:

• Legal Entity: Legally, FastSpring is the reseller of the software license. This is why credit card descriptors read FS* ahrefs.com or FastSpring Ahrefs.
• Tax Compliance: FastSpring automatically calculates and remits required regional digital service taxes to your government.

How to Add or Update Your VAT / GST Tax Number

If you run a registered business in the European Union, United Kingdom, Australia, or India, you can reverse-charge VAT so you are not charged tax:

During Initial Checkout:

1. On the FastSpring checkout window, look for the field labeled "Enter Tax ID" or "VAT ID".
2. Enter your full corporate tax identification number including the 2-letter country prefix (e.g., DE123456789 for Germany or GB123456789 for the UK).
3. FastSpring validates the code against the live VIES tax database. The tax will instantly drop to $0.00.

On an Existing Subscription:

1. Open your Ahrefs Billing tab > Manage Subscription.
2. Inside the FastSpring portal, select Edit Billing Details.
3. Insert your corporate VAT/GST number and save. All subsequent monthly billing cycles will be issued tax-free.

Troubleshooting Ahrefs FastSpring Payment Declines

If FastSpring rejects your credit or debit card, the cause is usually one of the following:

1. 3D Secure / OTP Verification Timeout

• Issue: FastSpring uses European PSD2-compliant 3D Secure verification. If your banking app takes more than 2 minutes to send an SMS code or push notification, FastSpring aborts the checkout.
• Fix: Keep your banking mobile app open on your phone before clicking "Pay Now".

2. VPN or IP Address Geolocation Mismatch

• Issue: FastSpring’s automated risk engine flags transactions if your IP address is in one country (e.g., via a US VPN) while your card was issued in another (e.g., India or Pakistan).
• Fix: Disable all VPNs and proxies, clear browser cookies, and checkout from your real local internet connection.

3. Recurring International Transaction Limit

• Issue: Many business debit cards allow one-time international purchases but block automated recurring SaaS subscriptions.
• Fix: Call your card issuer or toggle "International Recurring Payments" to ON inside your corporate mobile banking dashboard.
