Frequently Asked Questions
We hear these questions on almost every first call. Here are straight answers.
What are payment integration services?
Payment integration services connect a payment gateway or processor, such as Stripe, PayPal or Adyen, to your website, app or business software. They cover checkout, cards, wallets and local methods, subscriptions, refunds, payouts, security and syncing payments to your CRM and accounting, so customers can pay easily and the money is tracked correctly.
How much do payment integration services cost?
A single gateway integration usually costs $3,000 to $10,000 and takes 1 to 3 weeks. Subscriptions, marketplaces, several gateways or local methods cost $10,000 to $40,000 over 4 to 10 weeks. A dedicated payments team starts from about $3,500 a month. Gateway transaction fees are separate and paid to your provider. See our pricing section for what each option includes.
What is a payment gateway?
A payment gateway is the secure service that collects a customer's card or wallet details at checkout, sends them for approval to the bank and card network, and returns an approved or declined result, usually within seconds. Stripe, PayPal, Adyen, Square and Authorize.Net are common payment gateways.
What is the difference between a payment gateway and a payment processor?
A payment gateway captures and protects payment details at checkout. A payment processor moves the money between the customer's bank, the card networks and your merchant account. Most modern providers, such as Stripe, Adyen and PayPal, offer both together, so most businesses only need one provider.
What are integrated payments?
Integrated payments are built directly into the software your business already uses, such as your website, booking system, CRM or SaaS product. Customers pay without leaving your platform, and every payment links automatically to the right order, invoice and customer record, which saves manual work and reduces errors.
How do I integrate a payment gateway into my website?
Create an account with a gateway such as Stripe or PayPal, choose hosted, embedded or custom checkout, connect it through the gateway's API or plugin, set up webhooks for payment events, test every case in sandbox mode, then switch to live keys. We handle the whole process and test it before launch.
How long does payment gateway integration take?
A standard Stripe or PayPal integration takes about 1 to 3 weeks, including testing. Subscriptions, marketplaces or multiple gateways take 4 to 10 weeks. Account approval by the gateway can add a few days, especially for high-risk industries or new businesses, so we start that step early.
Which payment gateway is best for a small business?
For most small businesses selling online, Stripe, PayPal or Square are the best starting points: quick setup, no monthly minimums and support for cards and wallets. Square suits businesses that also sell in person. The best choice depends on where your customers are and how they like to pay.
Can you help us accept international payments?
Yes. We set up multi-currency pricing and add the local payment methods buyers trust, such as iDEAL in the Netherlands, UPI in India, Pix in Brazil, Mada and Tabby in the Gulf, and JazzCash in Pakistan. Where needed we add a second gateway with better coverage or lower fees in a region.
Is your payment integration PCI compliant?
We build integrations that follow PCI DSS by using tokenized, hosted payment fields, so raw card numbers never touch your servers. That keeps most businesses on the simplest self-assessment questionnaire, SAQ A. We also add 3D Secure 2, encryption, signed webhooks and restricted API keys.
Can customers pay with Apple Pay, Google Pay or BNPL?
Yes. We add Apple Pay, Google Pay and PayPal for one-tap checkout, and buy-now-pay-later options like Klarna, Afterpay, Affirm, Tabby and Tamara. Wallets and BNPL usually live alongside cards in the same checkout, so customers simply pick the option they prefer.
Can you set up subscriptions and recurring billing?
Yes. We integrate Stripe Billing, Chargebee or Recurly for plans, free trials, upgrades, usage-based pricing, invoices and taxes. We also set up automatic card updates, smart retries and dunning emails, so failed renewals are recovered instead of silently cancelling customers.
How do refunds, chargebacks and failed payments work?
Refunds and disputes are handled through the gateway, and we connect them to your admin panel so your team can refund, add dispute evidence and see status in one place. Failed payments trigger webhooks, retries and customer emails automatically, and everything is logged for your accounting.
Can you integrate local gateways like JazzCash, EasyPaisa, Tabby or Telr?
Yes. We integrate Pakistani gateways such as JazzCash and EasyPaisa, and Gulf gateways such as Telr, PayTabs, Tabby and Tamara, alongside global providers like Stripe. Each local gateway has its own approval process and API, and we manage the technical side from sandbox to live.
Will I own the payment integration and accounts?
Yes. The gateway accounts are opened in your company's name, the code is yours from the first commit, and API keys are stored in your own secure vault. We sign an NDA before you share anything private, and you can bring the integration in-house any time.
