Offering a payment method takes more than displaying a logo. You need an accepted provider account, a suitable connection and a verified order flow. Check the current name and availability with your provider; payment products can change. This guide covers the checks without promising fixed processing rates.
Does iDEAL suit your customers?
Investigate payment preferences in your target market and what your provider offers your account. iDEAL is relevant to Dutch customers, but buyers do not all use the same method. A provider’s catalogue listing does not prove availability through your particular platform connection and account.
From payment to order status
For one test payment, compare the order number, provider reference and final payment status. Record when the status changes in administration. If payment remains open or pending, investigate that reference first; do not create another payment or dispatch instruction based on the thank-you page alone.
Account, connection and activation
Create or use a business provider account and complete verification. Connect it using the supported platform route. Activate the method in the correct environment and distinguish live from test credentials. Restrict access rights and record who may change settings and respond to incidents.
Costs across your payment mix
Use the current contract: fixed components, percentages, international surcharges, currencies and any refund charges. MicroCart charges 0% own transaction fees; processing is not free. The subscription is €39.95 per store per month or €399.50 per year excluding VAT, including all MicroCart apps and B2B.
Choose additional methods
Compare the methods your customers actually need. Check availability by country and verify your integration. Do not add every provider option automatically. Compare payouts, customer support, disputes and refund handling as well as price.
Test checkout on a phone
On a phone, test both a successful payment and cancellation at the bank. Reopen the same basket afterwards. The customer should understand whether an order exists and how to retry safely. Check in administration that a repeated attempt does not produce two paid orders.
Distinguish status from payout
A paid order and funds arriving in your bank account are different events. Check the provider’s payout schedule, deductions and reports. Do not fulfil based on a customer screenshot. Decide how to investigate differences between orders, provider transactions and bank receipts.
Avoid common errors
Do not confuse a built-in connection with automatic account approval. Do not copy an old rate without a source and date. Do not assume status updates never fail: check delayed notifications. Prepare a process for duplicate payments and customers who paid but saw no confirmation.
Frequently asked questions
Do I need a payment account? Yes; follow provider and platform requirements for the account, verification and activation. Is the cheapest method always best? No; compare total costs and suitability. Does a fixed subscription exclude transaction fees? Only if the actual terms say so.
Before going live
Record one complete trial, including order status, provider reference, refund and reconciliation. Use provider test facilities first, then follow its live-verification instructions. Also read how to compare payment methods.
