Aquadratic

Overview

Aquadratic is a merchant-of-record service for independent creators, developers, and other digital-product sellers. It is best suited to sellers who want checkout, delivery, tax handling, and payouts in one service. Its main trade-off is clear: no monthly charge for the commerce platform, but a 7% transaction fee plus possible processor fees.

Key features

For each product, sellers can offer a hosted checkout URL, an embeddable widget, or connect through a REST API. That range accommodates a straightforward sales flow as well as a custom integration. Aquadratic accepts card payments via Stripe and PayPal, along with cryptocurrency; it also names Stripe, PayPal, and NOWPayments for processing integrations, and provides webhooks and API keys.

After payment, the service can email digital products and license keys automatically. As merchant of record, Aquadratic says it calculates, collects, and files sales tax and VAT worldwide, and manages disputes and chargebacks. That puts substantial operational work under one roof, which is useful for sellers handling international sales; the 7% charge is the price to weigh against that convenience.

AquaDrop is the separate download-delivery offering. It binds access to seller-issued license keys and uses per-buyer signed URLs that expire quickly; instant revocation is also included on Starter. Pro adds download caps, while Scale adds version channels and full API access. Those controls are useful for sellers who need to restrict or manage file access, but the monthly plans make sense only if the delivery quotas and tools justify a recurring cost.

Aquadratic says payment credentials are handled primarily by processors and that it does not keep complete card numbers or other full sensitive payment credentials on its servers. Its privacy policy says it does not sell personal information for third-party marketing. The homepage displays 99.9% uptime, PCI compliance, and SSL encryption. Support for orders, delivery, refunds, and general questions is available by email, with a stated response time of 24–48 business hours.

Refunds are generally unavailable for digital-product sales, though Aquadratic may offer a refund, replacement, or credit in specified cases. Requests should be made within seven days unless law requires otherwise. Buyers and sellers who need a more flexible refund policy should account for that limit.

Pricing

The Aquadratic platform has no monthly fee or per-transaction minimum, but charges 7% per transaction; processor fees may apply. It suits sellers who want the commerce and merchant-of-record functions without a fixed subscription, though the percentage can become a significant cost as sales grow.

AquaDrop has its own plans, so delivery quotas and commerce transaction fees should be considered separately:

• Starter: free, billed $0 forever. It includes 100 deliveries per month, 1 GB storage, signed URLs, license key binding, and instant revocation. This is a useful no-cost way to secure a modest delivery volume, but its storage and monthly quota constrain larger catalogs or busier products.
• Pro: $19 a month, billed $19/month. It raises the limit to 10,000 deliveries per month and 25 GB storage, and adds webhooks, a custom domain, and download caps. It fits sellers with regular delivery demand who need more control and integration options.
• Scale: $49 a month, billed $49/month. It includes Pro features, 100,000 deliveries per month, 250 GB storage, version channels, and full API access. This is for high-volume delivery or sellers who need release-channel and API controls; smaller sellers are unlikely to need its larger quotas.

Platforms

Aquadratic supports web and API access. It also offers an embeddable checkout widget, which gives web sellers a way to place checkout within their own pages rather than relying only on a hosted URL.

Who it's for

Aquadratic is a strong fit for independent digital-product sellers who value automated delivery and want tax collection, filing, dispute handling, and payouts handled as part of the commerce service. It is less compelling for sellers whose priority is minimizing per-sale fees, or who need a more permissive refund approach. AquaDrop Starter is appropriate for small delivery volumes; Pro and Scale suit progressively higher quotas and more advanced delivery controls.

Pros and cons

• Pro: Hosted checkout, an embeddable widget, and REST API access accommodate both simple sales and custom commerce integrations.
• Pro: Automatic delivery, worldwide sales-tax and VAT handling, and dispute management reduce separate operational tasks for digital sellers.
• Pro: AquaDrop Starter provides signed URLs, license-key binding, and instant revocation without a monthly fee.
• Con: The 7% commerce transaction fee, with processor fees potentially added, can weigh heavily on sellers with substantial sales.
• Con: Starter's 100 monthly deliveries and 1 GB storage are restrictive for larger or fast-growing products; higher quotas require paid plans.
• Con: Digital-product sales are generally final, with refund requests normally expected within seven days.

Alternatives

For a broader comparison, see Merchant of Record Software.

Polar is worth comparing for sellers who want a free plan with a 5% + 50¢ transaction charge and support across Android, iOS, web, API, and extension platforms; Aquadratic instead charges 7% and offers AquaDrop delivery tiers.

Coda may suit someone looking for a free plan for personal documents, but its free shared docs are limited to 50 objects and 1,000 table rows.

Tebex is an option for game sellers who want a free Starter plan with unlimited packages, charged at 5% for most games or 15% for FiveM, and a paid Plus plan at £12.49 a month.

Fungies offers a free-forever plan charging 5% + 50¢ per sale, with no monthly, setup, or per-seat charge and unlimited products, plans, and assets; it may suit sellers prioritizing those catalog and seat terms over Aquadratic's delivery controls.

Lemon Squeezy has ecommerce features without monthly charges and applies transaction fees when sales are generated, making it another option for sellers seeking a no-subscription starting point.

Gumroad is another option for digital-product sales, with separate direct-sales and marketplace fee structures.

Whop may be worth considering for high-volume businesses seeking tailored rates and a dedicated account manager.

Breeze is another merchant-of-record software option.

Verdict

Choose Aquadratic if you sell digital products and want payment, delivery, worldwide tax handling, dispute management, and payouts combined, with AquaDrop available for gated downloads. The strongest reason to look elsewhere is cost: its 7% transaction charge can add up, and processor fees may apply; its generally final-sale refund policy is another meaningful constraint.
