Payment integration
The Square integration lets customers pay your Invoice Crowd invoices through Square checkout, or start a card-on-file Square subscription on a subscription invoice. Square payment notifications are set up automatically when you save your Square details, and refunds go back through Square.
From setup to paid
Connection, customer checkout and final settlement are separate stages. Read the status and limitations before showing the method on a live invoice.
Each business profile has its own account and live or test mode.
Application ID, write-only access token, location ID and Live/Sandbox mode. Square payment notifications are then set up automatically.
Square controls merchant countries, location availability, currencies, fees and account review.
The payment option only shows when it can be used for that invoice.
Square Payment Links checkout is active and the completed provider payment is revalidated before local settlement.
Customers can start a card-on-file Square subscription from a subscription invoice, and each period is recorded when Square confirms the payment. Older subscriptions keep their existing renewal handling.
An invoice is marked paid only when the provider confirms it.
Completed Square payment, exact merchant/location and mode, invoice allocation, amount, currency and stable payment identity.
Invoice Crowd sets up Square's payment notifications for you when you save your Square details or switch between Live and Sandbox. If setup fails, that account's edit panel shows the reason.

Amount, currency and allocation are derived from the current server-side invoice state.
If a confirmed Square payment can't be applied to its invoice, for example because the balance changed after checkout started, Invoice Crowd holds it in Payments Needing Review. You then apply it to the invoice, keep it as customer credit, or refund it.
Choose Refund on the invoice in Invoice Crowd and the money goes back to the customer through Square. The refund is booked only after Square confirms it. This covers online payments made on the invoice page.
Gateway fees, exchange costs and settlement timing come from the merchant agreement, not the Invoice Crowd subscription.
Configure another active provider when this gateway does not support the merchant, customer, currency or collection model.
