- Task
- Show from which point manual punching of checks ceases to be possible: the checkout contains all common payment methods in Ukraine.
- Solution
- An OpenCart store with ten payment methods - card gateway, banking applications, installments from two banks, cashless with and without VAT, terminal, cash in advance - and four delivery methods.
- Result
- Measurement 07/31/2026: 10 payment methods and 4 delivery methods, catalog 6,486 pages of goods and 361 categories. First server response 671.2ms with 407.8KB markup. Critical Defect Found: Bare domain returns 301 on HTTP even though the certificate is valid. It is not visible from the site whether the payments are taxed here: the check lives in the cashier's office, and that is why we start with checking the calculations, and not with the code.
