@dannytaurus Thanks for putting this comparison together. I'm Aaron, the developer behind SoundSync. Your post highlighted some genuine gaps in our public documentation, so I've updated the site to make these details much easier to find and compare.
I've also attached a detailed 10-page reference covering the SoundSync entries in your comparison, newer features, and links to the relevant public pages:

Pricing and what's included
SoundSync charges one 10% fee on SoundSync-managed sales, with ordinary payment processing included. There is no additional marketplace fee and no fixed per-sale SoundSync charge. For example, a $49 sale has a $4.90 SoundSync fee, leaving $44.10 for the developer before any agreed affiliate/collaborator shares. Tax is handled separately from product earnings.
The $10 monthly minimum is a minimum, not another subscription charge on top: SoundSync fees already incurred that month, including sales fees and usage charges, count toward it. If those total $7, the shortfall is $3; if they total $10 or more, there is no minimum top-up. Paid products, bundles, and subscriptions must be $9.99 or higher after discounts, before tax.
Transactional emails are included. Marketing email includes 1,000 sends per month, then $1 per started block of 1,000 additional sends. Qualifying free claims and external serial redemptions include 10,000 per month, then $0.005 per additional redemption. These allowances reset monthly without rollover. Normal licensing validation calls are not billed as external redemptions, and a free BOGO gift included in a paid checkout does not incur an external-redemption charge.

Payments, Merchant of Record, and the business behind it
PayPal is supported for one-time checkout, alongside Stripe payment options. Recurring subscriptions currently use Stripe. Products and checkout currently use USD only; this is not a claim of local-currency pricing. Any provider currency conversion is separate, and developers bear applicable conversion costs when receiving funds in another currency.
SoundSync Solutions is the Merchant of Record for SoundSync-managed checkout, including developer storefront and marketplace sales processed through that checkout. SoundSync handles the applicable sales-tax/VAT responsibilities for those sales. The tax page lists current country coverage and explains the scope; developer income taxes remain the developer's responsibility. An external reseller collecting its own payment is different: SoundSync does not absorb that reseller's processing fees or become its Merchant of Record merely by fulfilling a serial or entitlement.
SoundSync Solutions is based in Michigan, USA. The business address is 2632 Crossing Circle #1010, Traverse City, Michigan 49684, and support is support@soundsyncsolutions.biz. The site now has substantive Terms and Privacy information, rather than just headings, plus retention and account-closure details.

Where funds are held, and when payouts happen
Funds collected through Stripe and PayPal are transferred manually to a dedicated business account used only for developer, affiliate, and collaborator payouts, not business expenses. Developer payouts are made through Stripe Connect. This is a dedicated payout account, not a claim of escrow or deposit insurance.
Payouts are scheduled twice monthly, on the 1st and 15th, after at least a 14-day hold. Eligible funds go into the next scheduled payout after that hold completes. There is no SoundSync payout minimum or routine reserve. The scheduled date means payment initiation, not a guaranteed bank-arrival date; unresolved disputes, account restrictions, or payout-destination issues can affect an individual balance.

Refunds and disputes
Customers request refunds from the product developer within 14 days of the initial purchase. Authorized developers can refund the full order or selected whole products; arbitrary cash amounts and fractional refunds of one product are not supported. For subscriptions, the standard refund policy covers the initial payment, not renewals, with mandatory consumer rights still applying.
The customer receives the refunded product's paid amount and associated tax. SoundSync retains its original share, and the developer is responsible for actual additional refund charges and confirmed chargeback/dispute losses. This is separate from ordinary checkout processing already included in the 10% fee. Affiliate/collaborator shares reverse according to the original allocation. Access associated with the refunded purchase is withdrawn; unrelated purchases are not removed.

HISE, JUCE, licensing, and delivery
There are now two HISE integration paths: HISEScript, for easier integration without modifying HISE source, and native HISE C++, which requires patching/rebuilding HISE and offers stronger native enforcement. The JUCE package is also available, with activation, processor-owned licensing, and Store/My Products integration. Package-specific requirements matter: HISEScript documents configurable offline grace following a valid state, while the current JUCE release requires online renewal at startup and does not provide offline audio access.
The public API reference includes serial claims and claim status, activation, customer-login activation, validation, and deactivation, with authentication and request/response details. File delivery uses authorized customer downloads, and the customer library brings together owned products, downloads, serials, device access, and support.

Storefronts and branding
SoundSync supports hosted storefronts and a full embedded commerce experience, including catalog, product pages, cart, checkout, and customer access. Custom domains can use the main domain, not just a shop/store subdomain. Developers need domain control and DNS access; SoundSync provides guided setup and manages the hosted connection and SSL certificates once verified. Brand Manager covers logos, light/dark branding, colors, imagery, support details, and the supported brand settings reused across the storefront and other surfaces.

Affiliates, collaborators, teams, and resellers
There are dedicated native affiliate and collaborator programs, not just reseller attribution under another name. Affiliates use agreed product/rate terms and referral links; collaborators use product revenue-sharing agreements. Their earnings and payouts are tracked separately. Team Accounts are a separate permissions system, so a revenue-sharing agreement does not automatically grant dashboard access. Approved resellers also have serial, external-order, fulfillment, and API integration paths, including WooCommerce.

Email, growth, subscriptions, and marketplace discovery
Marketing includes campaigns, audience management, scheduling, reports, and growth flows such as cart recovery, onboarding, review requests, follow-ups, and winback. Promotions include scheduled deals and supported codes/offers. Subscription documentation distinguishes recurring access from models where paid invoices earn product ownership.
Marketplace discovery is included in the same commercial model. Launch into an ecosystem backed by nearly 50,000 established audio-software customers.

Two clear "no" answers for the comparison
We do not currently offer assisted Gumroad migration or pay-what-you-want pricing. Imports and external fulfillment should not be described as a Gumroad account-migration service.

SoundSync is still a newer platform, and I understand that documentation is only part of evaluating one. My aim here is to make the commercial details and integration requirements public and easy to check, rather than leave you guessing. Thanks again for calling out what was missing.
