For QBO app developers
Your sandbox has 3 invoices.
Your users have 3,000.
Load realistic test data into a QuickBooks Online (QBO) sandbox so your app meets partial payments, credits and volume before your users' books do.
What your integration gets to see
From one run of --template saas --scenario rapid-growth --seed 42 for Sep 2025 – Aug 2026:
Receivables
Multi-line invoices with due dates from the template's payment terms, full and partial payments, unpaid invoices, credit memos, refund receipts, estimates and deposits.
Payables
Multi-line bills across industry expense categories, bill payments, vendor credits, purchase orders and direct expenses.
Payroll and adjustments
Semi-monthly payroll expenses (wages, taxes, optional benefits), depreciation and accrual journal entries, and bank transfers.
Realistic parties, safely tagged
Customers, vendors and employees get realistic names, addresses, emails and phone numbers, and every generated record carries the EZTD tag. Purge deletes the transactions it added, makes its customers, vendors, employees and items inactive (accounts stay), and never touches records you made by hand (details).
