We develop custom payment software that unites virtual POS, digital wallet, reconciliation and invoicing flows in a single secure system, built on iyzico, PayTR and bank POS infrastructures.
Payments and fintech integration is the work of making a business's collection, payment and money-movement processes orderly, traceable and secure at the software layer. In practice that means connecting a virtual POS to your website or dealer panel, applying instalment and commission rules correctly, matching the bank statement against sales records (reconciliation), and making every collection invoiceable. Adding a single payment button is easy; the real difficulty is handling real-life scenarios such as failed transactions, refunds, partial collections and month-end reporting in a recorded, traceable way.
Ready-made plug-ins and standard modules cover most small scenarios; but their limits show quickly once multi-channel sales, different commission structures per dealer, foreign-currency and export collections, or exact reconciliation with an ERP are required. Custom development lets you build the payment flow around your business's own rules, and switch between iyzico, PayTR or a direct bank POS without provider lock-in. We build an architecture that works with tokenisation and provider-hosted screens, without holding card data in your systems, to reduce your PCI DSS burden.
At Pan Innovation House we develop the payments side API-first and iteratively: first a secure, testable collection flow, then reconciliation, invoicing and reporting. The source code we write and your data are handed over to you as defined in the contract; third-party and open-source components remain subject to their own licences. Every critical flow goes through a review step before it goes live, and the maintenance scope after go-live is defined in the contract. Because this is a high-sensitivity area, we pin down time and cost after the scope is defined, not with made-up figures.
For carpet, machinery, textile and food companies collecting through the corporate website, the dealer panel and marketplaces alike, we build flows that gather every payment channel into a single reconciliation and reporting screen. For overseas collections you can also calculate currency and commission rules precisely.
For businesses selling to dealers on credit terms and working with account balances and credit limits, we develop a payment layer that automatically matches card, bank transfer and virtual POS collections against the customer account. Each dealer's commission and instalment rule can be defined separately.
For platforms, associations and service businesses taking regular payments, we build recurring collection with stored cards (tokenisation), retries on failed charges and automatic notifications; card data is stored with the provider, not with you.
For SMEs that want sales, collection and invoice data talking to Logo, SAP or their own ERP, we develop integrations that automate bank statement-to-sales reconciliation and the e-invoice/e-archive processes run through a private integrator.
We build card collection with iyzico, PayTR and bank virtual POS infrastructures: 3D Secure verification, instalment and commission rules, BIN-based instalments and provider-hosted payment screen integrations. We aim for a switchable architecture with no single-provider lock-in.
We manage balance top-ups, spending, refunds and transfers per user or dealer with a traceable ledger logic. Every movement can be traced back; balances stay consistent with the accounting record.
We develop automatic reconciliation that matches the bank statement, the provider report and your own sales records. Missing, surplus and unmatched items are flagged, which makes end-of-day and month-end close faster and more controlled.
We build flows that make every successful collection invoiceable and run GİB-compliant e-invoice and e-archive processes through an integrator. The link between collection and invoice is kept, and reporting stays consistent.
We put the hard part of real life under software control: retrying failed transactions, partial refunds, double-charge protection (idempotency), timeouts and webhook result verification. Consistency in money movement is our priority.
We build an architecture that works with tokenisation and provider-hosted screens without storing card data in your systems; sensitive data is masked in logs, with authorisation and an audit trail throughout. The aim is to reduce your PCI DSS scope and your risk.
We develop a management panel showing collections, revenue, commissions, refunds and reconciliation status on one screen, with automatic alerts for failed payments or inconsistencies and exportable reports.
We map which channels you collect through, in which currencies and under which rules. Provider selection (iyzico, PayTR, bank POS), the instalment-commission structure and refund and reconciliation needs are pinned down; time and cost are set against this scope.
We design an architecture that stores no card data, using tokenisation and provider-hosted screens. Authorisation, audit trail, idempotency and webhook verification enter the design from the start; PCI awareness lands in the code, not on paper.
We test payment, 3D Secure, refund, partial collection and failed-transaction scenarios end to end in the providers' sandbox and test environments. Every critical flow goes through a review step before it goes live.
Once the collection flow is solid, we add bank statement matching, e-invoice/e-archive and the management panel. We set up the data flow with your ERP or accounting system (Logo, SAP or custom) and automate the end-of-day close.
We start with a controlled go-live, real transaction monitoring and alerting mechanisms. Afterwards, under the maintenance scope defined in the contract, we manage provider updates, new rules and reporting needs. The source code we write and your data are handed over to you as defined in the contract; third-party and open-source components remain subject to their own licences.
We do not quote a fixed figure, because cost and duration vary with the number of channels, the provider selection, reconciliation and invoicing needs and the ERP connection. In a discovery call we pin down the scope and present a realistic, written proposal. We do not give made-up prices or timelines.
No. We build the architecture so card data is never stored in your systems; we work with tokenisation and provider-hosted payment screens. That approach reduces your PCI DSS scope and your risk. Sensitive data is masked in logs, and transactions are recorded with an audit trail.
We develop integrations with iyzico, PayTR and the banks' virtual POS infrastructures. We aim to build the architecture without locking into a single provider, so adding or switching providers later does not require a fundamental rewrite.
Yes. The source code we write and your data are handed over to you as defined in the contract; third-party and open-source components remain subject to their own licences. We leave a documented codebase, free of provider lock-in, that your own team or another team can maintain.
Yes. Because we work API-first, we can connect the payment layer to your existing website, dealer panel or ERP/accounting system (Logo, SAP or custom systems). Bank statement reconciliation and the e-invoice/e-archive flows run through your private integrator can also be included in that integration.
Yes. In an area as critical as payments, post-launch support is essential. Under the maintenance scope defined in the contract we manage transaction monitoring, provider updates, new business rules and your reporting needs.
We listen to what you need and tell you whether custom development or an off-the-shelf product fits better. The first 30-minute call is free; the scope of an on-site discovery, and its fee if any, is agreed in writing during that call.
We build a system that shows you the true cost at quotation stage: raw material, scrap, labour, energy, tooling, packaging, freight, customs and payment-term costs gathered per product; currency and payment-term scenarios; a price band set against your target margin; and the win rate of past quotations.
Details →For e-exporters selling direct to consumers in Europe, we build a system that tracks country-level obligations in one place: thresholds, the filing calendar, invoice formats, producer responsibility registrations, and the different liability regimes of marketplaces versus your own site.
Details →We audit your website, e-commerce store and customer portal against accessibility criteria, rank the findings by priority and apply the fixes. The goal is not a badge; it is an interface that is genuinely usable.
Details →Custom business intelligence and reporting solutions that bring the data scattered across spreadsheets and systems into a single decision screen. Clean data through ETL, real-time KPI dashboards, and reports segmented by role.
Details →We develop custom automation solutions that remove repetitive manual work, copy-paste reporting and waiting on approvals — and connect your systems to each other.
Details →We are not talking about an off-the-shelf chatbot, but an AI layer that works on your own data and produces measurable gains. We weave chatbots, customer assistants, document understanding (RAG), internal search and report generation into your organisation's processes — and the source code we write is handed over to you.
