Aquadratic

Aquadratic is merchant-of-record infrastructure for creators, developers, and other digital-product sellers. It is best for businesses that want checkout, delivery, tax administration, and dispute handling combined rather than built from separate services. The central trade-off is a free commerce plan with a 7% transaction charge, alongside optional AquaDrop plans for controlled, quota-based downloads.

Overview

Aquadratic handles payment collection, digital delivery, global tax compliance, fraud protection, and seller payouts. That scope makes it a practical fit for an independent seller that needs more than a payment button but does not want to operate its own tax and chargeback processes. The 7% transaction fee means the service becomes materially more expensive as sales grow, especially when processor fees are added.

AquaDrop is a separate delivery layer. Its license-key gating and expiring, buyer-specific links address a different concern: limiting how downloadable files are accessed after purchase. Sellers should decide whether they need that extra delivery product or only Aquadratic's core commerce workflow.

Key features

Every product can expose a hosted checkout URL, an embeddable widget, or a REST API. A hosted page suits a straightforward launch, while the widget and API are better for a branded product flow or a team connecting commerce to an existing application. Webhooks and API keys support further integration.

Payments include cards through Stripe and PayPal, plus cryptocurrency. Aquadratic names Stripe, PayPal, and NOWPayments as payment-processing integrations. The range is useful for sellers serving customers with different payment preferences, although the platform fee remains separate from any processor charges.

After payment, Aquadratic can email license keys and digital products automatically. In its merchant-of-record role, it says it calculates, collects, and files sales tax and VAT worldwide and manages disputes and chargebacks. That transfers substantial administrative responsibility away from a small seller, but the service fee is the price of that coverage.

AquaDrop ties downloads to seller-issued license keys and uses signed URLs for each buyer that expire quickly. Starter also provides instant revocation; higher plans add download caps and, on Scale, version channels and full API access. The approach is more suitable for licensed software and other files where access control matters than for an unprotected, one-off file handoff.

Payment data is handled primarily by processors, and Aquadratic says it does not store complete card numbers or other full sensitive payment credentials on its servers. Its stated privacy policy does not sell personal information to third parties for their own marketing. The homepage displays 99.9% uptime, PCI compliance, and SSL encryption. Support for orders, delivery, refunds, and general issues is offered by email, with a stated response time of 24–48 business hours.

Digital sales are generally final. Aquadratic may issue a refund, replacement, or credit in specified circumstances, and requests should be made within seven days unless applicable law requires otherwise. Sellers whose customers expect broad, no-questions-asked returns should account for that policy.

Pricing

Aquadratic platform

The core platform costs nothing, with no monthly fee or per-transaction minimum. Aquadratic bills 7% per transaction, and processor fees may apply. This is the natural starting point for independent creators who want the full commerce and merchant-of-record scope without a subscription, provided the percentage remains acceptable at their sales volume.

AquaDrop Starter

Starter costs nothing and is billed $0 forever. It allows 100 deliveries per month and 1 GB of storage, with signed URLs, license-key binding, and instant revocation. Those caps suit a small catalog or early launch; they can become restrictive for frequent downloads or larger files.

AquaDrop Pro

Pro costs $19 a month, billed $19/month. It raises capacity to 10,000 deliveries per month and 25 GB of storage, and adds webhooks, a custom domain, and download caps. Choose it when delivery volume and branded or automated workflows justify a fixed monthly bill.

AquaDrop Scale

Scale costs $49 a month, billed $49/month. It supports 100,000 deliveries per month and 250 GB of storage, adds version channels and full API access, and includes Pro features. This is aimed at high-volume catalogs or products needing release-channel control; it is unnecessary for a small seller within Starter's limits.

Platforms

Aquadratic runs on the web and through an API. The web route covers hosted commerce operations, while the API supports custom product and integration flows.

Who it's for

Independent creators, developers, and digital-product suppliers are the clearest audience. It is particularly well suited to sellers who value worldwide tax filing and chargeback management, need automatic license or file delivery, and prefer a no-monthly-fee core plan. It is less compelling for high-volume businesses that can secure materially lower transaction costs elsewhere, or for sellers whose delivery needs exceed AquaDrop's quotas without wanting a monthly subscription.

Pros and cons

Pros

Merchant-of-record coverage combines payment handling, worldwide sales-tax and VAT administration, disputes, and payouts.

Hosted checkout, an embeddable widget, and a REST API cover both simple launches and custom integrations.

Automatic email delivery of license keys and products reduces post-purchase handling.

AquaDrop provides license-key binding, expiring signed URLs, and revocation controls for gated downloads.

The core platform has no monthly fee or per-transaction minimum.

Cons

The core 7% transaction charge can outweigh a subscription-based alternative as sales volume rises, before processor fees.

Starter's 100 monthly deliveries and 1 GB storage limit its usefulness for active catalogs.

Refunds are generally final and requests normally must arrive within seven days.

Pro and Scale add recurring costs that may be hard to justify for occasional or low-volume downloads.

Alternatives

Merchant of Record Software is the broader category to compare when you want to survey other services with similar tax and payment responsibilities.

Coda is worth choosing instead if you need Android and iOS apps alongside web and API access, with a free plan whose personal documents have no size or object limits.

Polar fits sellers who prefer a 5% + 50¢ free-plan transaction charge or a $20/month Pro tier rather than Aquadratic's 7% rate.

Tebex is the alternative to consider for game-oriented selling, with a free Starter plan and package-based pricing.

Fungies suits sellers seeking a free-forever plan with unlimited products, plans, and assets and a 5% + 50¢ per-sale charge.

Breeze is another merchant-of-record option with API, iOS, and web support.

Freemius is a fit when transaction pricing of 3.8% + 50¢ plus gateway fees, with no setup or monthly fees, is preferable.

Gumroad is an alternative for profile or direct-link sales priced at 10% + $0.50 per transaction.

Whop is the option to investigate when you need a tailored, high-volume commercial arrangement.

Verdict

Choose Aquadratic if you are an independent digital seller who wants merchant-of-record tax and dispute handling, flexible checkout integration, and automatic delivery without a monthly core-platform fee. Look elsewhere when a 7% transaction cost is too high at your volume, when you need broader mobile-platform coverage, or when your download traffic makes AquaDrop's paid quotas poor economics.
