Frequently asked questions

For standard models the minimum order quantity starts at 50–100 units depending on the device. We also ship single-unit samples so you can test integration before committing.

Standard configurations ship in 15–25 working days after order confirmation. OEM orders with custom branding or firmware typically take 30–45 days.

EXW, FOB Guangzhou/Shenzhen and CIF to major European ports. For regular volume we can discuss DDP into EU warehouses.

Yes — the OpenAPI reference, SDKs (Java, Python, PHP, Node.js) and integration examples are available in English. Integration support is included during onboarding.

The Wi-Fi and 4G models speak HTTP REST and MQTT, holding a single outbound TLS connection, so nothing needs inbound ports opened at the customer site. USB-only models (GBL-SMU, GBL-SLU, GBL-P80AUC, GBL-B-P58U) have no network stack of their own — they behave as local USB devices for the host POS, and any cloud layer runs in your software on that host.

Core local functions keep working — printers keep a buffer and print on reconnect, and the GBL-IBDW Receipt Data Analytics Box consolidates receipt data offline until the link returns. Cloud-dependent features resume when the connection is back.

CE and RoHS as standard for the EU market; ISO 9001 for the quality system. Additional market-specific approvals (e.g. FCC for the US) can be planned into production — tell us early.

Yes. Sample units are shipped worldwide, usually within a week. The sample cost is credited against your first volume order.
