Operate, recover and reconcile connected EFTPOS safely.

Before production use

Confirm the merchant account, terminal, credentials and pairing belong to the correct business and site. Complete payment logon, a low-value controlled purchase and the provider's required settlement or reconciliation checks before opening trade.

Normal purchase flow

StamPOS records the sale and payment attempt, sends the amount through the configured Linkly connection and stores the returned outcome and references. The operator should wait for the final on-screen result and follow the terminal prompts.

Declined and cancelled transactions

A decline or cancellation does not complete the sale as paid. The operator may select another payment method or retry only after confirming the previous attempt has a final unsuccessful status.

Unknown or interrupted result

Do not immediately repeat a card payment when the result is uncertain. Use the StamPOS recovery workflow and Linkly transaction-status information to determine whether the original attempt was approved, declined or remains unresolved. Repeating an unresolved payment can create a duplicate charge.

Refunds

Refund access should be limited to authorised roles. Confirm the original sale, amount, reason and applicable provider requirements. Retain the refund result and references with the business records.

Receipts

StamPOS may print the POS sale receipt through the configured Windows printer while the payment terminal follows its own receipt configuration. Confirm the production receipt arrangement during deployment and do not assume every terminal or acquirer uses identical receipt settings.

Settlement and reconciliation

At the end of the trading period, compare StamPOS card totals with the Linkly/provider or acquirer totals. Investigate unknown, duplicate, reversed or missing outcomes before treating the period as closed.

Support evidence

For a payment issue, record the date and time, amount, StamPOS transaction reference, Linkly or provider reference, terminal identity, displayed outcome and whether recovery was attempted. Never send full card details, PINs, secrets or production credentials in support messages.

Accreditation scope

Accreditation confirms the assessed StamPOS integration against the applicable Linkly process. It does not replace merchant onboarding, acquirer approval, site testing, correct configuration or responsible operational procedures.
