Payments for online stores
Move data between systems without retypingConnect your checkout to the payment provider and reconcile the result against the original order.
Is this for you?
You run a store and several systems.
The same data gets typed into two places.
The team knows what transferred and what needs review.
How you buy it
Sites & Online Stores
A custom site or store that brings in work and connects to what runs behind it.
- Field and identifier mapping
- Error handling and documentation
What decides the cost
A fixed price per package, in a written quote within 2 business days after a free 30-minute call.
- Which systems connect and what access their interfaces require
- Which records move, in which direction, and how often
- Which failures the team can retry and which need manual review
You own the code. The care plan is cancellable, no lock-in.
How it runs
What it looks like
What we verify before connecting
Start with a sample from your workflow. Verify who sends, who receives and how a failure is reported.
Connections and how they work
Cardcom
WooCommerce sends the order to Cardcom. The payment outcome and reference return to the order.
If the response times out, look up the original transaction before retrying.
Technical documentation CardcomVerifone
The store sends a payment request to Verifone and receives the transaction reference and status.
An uncertain payment stays pending until the gateway confirms it, before any document is issued.
Technical documentation VerifoneAnother payment provider
A documented API can support a custom connection from store checkout to the provider and back to order status.
Define how declines, cancellations and missing responses are handled before launch.

Questions we get every week
Still unsure? A person answers on WhatsApp, within one business day.
Can you save a payment method or charge it again?
A Cardcom token can support later charges on an enabled terminal. Refunds can also be integrated.
Can an invoice or receipt be issued automatically?
A confirmed transaction can go to your connected invoicing system under that system’s rules.
What do you need to assess another gateway?
API documentation, a test environment and the provider’s security requirements.
