We build that layer — the part clients never see and cannot afford to have fail. Systems are designed for peak-season load, instrumented so problems surface before users notice them, and documented so your own team can operate and extend them.
The fintech toolkit. Built for business outcomes.
bill_line is a fintech software company developing infrastructure technology for payment providers, fintech companies, banks, and enterprises.
Technology that powers payment operations
Behind every checkout there is machinery that has to hold: transaction processing, provider integrations, reconciliation, monitoring, alerting.
-
Customised Checkout
Create branded checkout experiences optimised for conversion. We build the payment page as part of your product — your design, your flow, your language — with card, wallet and local method forms, and ready layouts so the team can test what actually converts.
-
Routing & Cascading
Intelligent transaction routing across acquiring and PSP integrations. We implement rule engines, provider failover and retry logic, so declined or degraded traffic is re-attempted automatically instead of ending at the first refusal.
-
Recurring payments
Automate subscription billing and recurring payment workflows. We develop scheduling, tokenisation, dunning and retry mechanics — daily, weekly, monthly or on whatever cycle your product needs — with full control over plans and billing states.
Accept payments in different currencies
bill_line ensures an efficient multicurrency with favourable conversion rates. Our partners' focus in EUR and USD, but we are able to connect local currencies in 50 countries
