What are the limitations of DEV3 Palletra I should know before buying?

Good to know

• Live payment gateways, SMS and push were not tested with real accounts. Card payments run on a simulated gateway by default, and push and SMS use simulated or log drivers. The rule that money lands only when the gateway confirms was tested against the simulated gateway. Run your own sandbox payments before taking real ones.
• The apps were not tested on physical devices. Both build as debug Android packages and run on the iOS simulator. The buyer app's real-server path (sign-in, invoice list, invoice detail, paying by invoice id, the invoice PDF) was exercised over HTTP against a seeded local backend. The rest of both apps was tested against a built-in mock and API responses captured from the backend, so plan your own end-to-end pass on a phone.
• No re-invoice flow after voiding an invoice. Voiding reverses the ledger and counters, and only works on an invoice with no payments applied. Creating a new invoice for the same shipment is not built.
• Early-payment discount and returns. A return after the discount was taken is credited only for what the buyer paid for those lines, with tax credited in full. If goods are returned before the invoice is paid, the discount is still worked out on the original invoice subtotal.
• Freight is not credited by a return. Return credit notes cover goods and tax only.
• One supplier, one base currency. Palletra is a single-seller platform. Each company has one currency, and dashboards convert EUR to USD with the exchange rates you maintain.
• Tax is table-driven. Rates are looked up by country, region and tax class, and tax-exempt documents are checked for approval and expiry. It is not a tax engine and was not checked against any real jurisdiction.
• No carrier integration. Carrier, tracking number and route points on a shipment are entered by staff or the demo data.
• Databases: MySQL 8 and SQLite were tested. MariaDB and PostgreSQL were not.
• Languages: English, with an Arabic translation and right-to-left layout. The Arabic file is not guaranteed to cover every string.
• Name: Palletra is a working name checked by a web search only, not a trademark clearance. Check it before you launch under it.
• No hosted demo. All companies, people and products in the screenshots are fictional.
