02Pricing at real usage
Paddle has no free plan or monthly fee on its Pay-as-you-go plan. The pricing page lists 5% + $0.50 per Checkout transaction; businesses selling products under $10 can contact Paddle for bespoke pricing. Paddle offers custom pricing for high-volume or complex businesses, including transactions under $10, but does not publish a rate.
Checkbook also has no free plan. Its Business plan is listed at $2,000/month and includes payments, invoices, multi-party checks, CSV upload, API access, approvals, white-labeling, live support and a dedicated CSM. Enterprise pricing is custom. Checkbook also charges per transaction, but its rates are not published.
Paddle's cost grows with each Checkout transaction, while Checkbook's Business fee is fixed monthly before transaction charges. Compare expected payment volume, and ask Checkbook for per-rail rates and Paddle for a quote if you qualify for custom pricing.
03API, SDKs and integration
Checkbook offers a RESTful API to send and track payments, send batches and onboard customers. Teams can also use its online dashboard. Its white-label tools let marketplaces customize colors, emails, content and payment flows. Pre-built integrations include QuickBooks Online and Accounting Seed; the pricing page also lists QuickBooks and Sage Intacct.
Paddle combines payments, subscriptions, localized checkout, sales tax and compliance in its Merchant of Record platform. Its homepage also describes ProfitWell Metrics for subscription, retention and growth metrics, plus Retain for failed-payment recovery and cancellation reduction. It does not name a specific API in the homepage content.
Neither homepage specifies SDK languages or a CLI. Checkbook has a Developer sign-in, while Paddle links to a Help Center. Before implementation, verify current API documentation, SDK support, webhook behavior and integration coverage with each vendor; do not assume an SDK or command-line workflow is available.
04Open source, self-hosting and lock-in
Neither vendor identifies an open-source licence, self-hosting option or data-export path on its homepage. Both are presented as web platforms, so plan around vendor-managed services rather than assuming you can run either product in your own infrastructure.
Paddle takes on payment, tax, compliance and billing as Merchant of Record. That can reduce the systems your team operates, but it also puts checkout and subscription workflows inside a provider's platform. Checkbook provides disbursement rails, an API and dashboard, with integrations for accounting tools. Replacing either service would mean adapting the payment flows that depend on it; the effort depends on your implementation.
Before committing, ask both vendors what customer, transaction and subscription data you can export, in which formats, and how long access continues after cancellation. Confirm migration support and how to move recurring billing or payout workflows.
Questions people ask
What are checkbooks for?
A checkbook traditionally holds paper checks used to pay people or businesses. Checkbook is a business disbursement platform: it sends payments through options including ACH, real-time payments, printed or mailed checks, push to card and virtual cards.
Why am I getting charged by Paddle on my credit card?
Paddle says it handles payments for digital-product businesses and provides a support route called “Why has Paddle charged me?” Check your receipt and subscription details, then contact Paddle payment support if the charge is unclear. The charge name alone does not identify the specific purchase.
Do people still use checks in 2026?
Checkbook supports printable and mailed checks alongside ACH, real-time payments and card payouts. That shows checks remain an available payment option on its platform, but the company does not provide data about how commonly people or businesses use them.
Do people still balance checkbooks?
Balancing a checkbook means comparing recorded payments and deposits with a bank statement to spot errors or missing transactions. It is a personal bookkeeping practice, separate from Checkbook's business payment platform, which sends and tracks disbursements.
