Lemon Squeezy is popular with indie SaaS founders. ProofCap connects directly to their API and reads the full paid order history โ so you verify the numbers at the source, not from a PDF.
The problem
Why self-reported data isn't enough
LS acts as the merchant of record, meaning payouts to the seller are after their fees and refunds. The 'total revenue' shown in their dashboard is gross sales โ the actual payout to the seller is lower.
Many Lemon Squeezy businesses run AppSumo-style lifetime deal campaigns. These create a one-time revenue spike that inflates annual run-rate projections but produces zero recurring revenue going forward.
Like all self-export platforms, the seller chooses the date range and filters. A seller can export only their best months or exclude refunded transactions.
The fix
ProofCap connects to Lemon Squeezy's API using the seller's API key (read-only scope) and pulls the full paginated order history โ every paid order, every refund, every status.
We separate one-time payments from subscription revenue and flag if the revenue is dominated by a historical LTD campaign rather than recurring subscriptions.
We construct the month-by-month revenue chart from raw order data โ not from the dashboard's pre-computed metric, which may smooth or misrepresent the trend.
Session data from the seller's GA4 account is compared against the order volume and implied conversion rate โ flagging when the math doesn't add up.
ProofCap reads the full Lemon Squeezy order history via their REST API โ including refunded, disputed, and voided orders that a seller-prepared export would omit.
