Lemon Squeezy produces payout invoices with auto-generated unique numbers. These are unique only within Lemon Squeezy, not within a company, thus posing a risk of issuing an already-used company invoice number.
Consider last year’s invoice 500,000. Lemon Squeezy could inadvertently reissue this, illegally duplicating an invoice number.
To avoid this, platforms like Polar use prefixes, for example, ‘POLAR-36273’ instead of ‘36273’. Lemon Squeezy should adopt similar strategies, either adding an ‘LS-‘ prefix or enabling user-customizable prefixes. Without these precautions, there are possible legal complications from duplicate invoices.
