Frequently asked questions Everything you need to know about our Finance & Banking software development service. ### What compliance standards do you build to for financial software? We build to the compliance standards required by the project — not a generic checklist. For payment systems: PCI-DSS (all relevant SAQ levels depending on card data scope). For EU financial products: PSD2 open banking API requirements, GDPR data handling, and MiFID II reporting where applicable. For US financial platforms: SOC 2 considerations, AML transaction monitoring, and relevant CFPB regulations. We treat compliance as an architecture constraint from day one — not a sign-off step at the end. ### Can you modernize our existing banking or financial platform? ### How do you approach security for financial applications? ### Do you have experience with open banking and API-first financial products? ### Can you work with both early-stage fintech startups and established financial institutions? ![](data:image/svg+xml,%3csvg%20width='44'%20height='46'%20viewBox='0%200%2044%2046'%20fill='none'%20xmlns='http://www.w3.org/2000/svg'%3e%3cpath%20d='M19.6667%203.33333H12.2C8.27966%203.33333%206.31948%203.33333%204.8221%204.09629C3.50496%204.7674%202.4341%205.83827%201.76298%207.1554C1.00003%208.65278%201.00003%2010.613%201.00003%2014.5333V26.6667C1.00003%2028.8366%201.00003%2029.9216%201.23855%2030.8117C1.88582%2033.2274%203.77265%2035.1142%206.1883%2035.7615C7.07846%2036%208.16343%2036%2010.3334%2036V41.4495C10.3334%2042.6928%2010.3334%2043.3145%2010.5882%2043.6338C10.8099%2043.9114%2011.146%2044.073%2011.5013%2044.0726C11.9098%2044.0722%2012.3953%2043.6838%2013.3661%2042.9071L18.9322%2038.4543C20.0692%2037.5446%2020.6378%2037.0898%2021.2708%2036.7664C21.8325%2036.4794%2022.4304%2036.2697%2023.0482%2036.1429C23.7446%2036%2024.4727%2036%2025.9288%2036H29.4667C33.3871%2036%2035.3472%2036%2036.8446%2035.237C38.1618%2034.5659%2039.2326%2033.4951%2039.9037%2032.1779C40.6667%2030.6806%2040.6667%2028.7204%2040.6667%2024.8V24.3333M40.9498%203.05025C43.6834%205.78392%2043.6834%2010.2161%2040.9498%2012.9497C38.2161%2015.6834%2033.784%2015.6834%2031.0503%2012.9497C28.3166%2010.2161%2028.3166%205.78392%2031.0503%203.05025C33.784%200.316582%2038.2161%200.316582%2040.9498%203.05025Z'%20stroke='%231A3760'%20stroke-width='2'%20stroke-linecap='round'%20stroke-linejoin='round'/%3e%3c/svg%3e) ## How can we help?
