Buying and running software in the United Kingdom
UK buyers tend to ask about data handling earlier in the conversation than buyers elsewhere, and the answers need to be specific rather than reassuring. Under UK GDPR that means naming where data is stored, how long it is kept, who can reach it and what happens on a deletion request — decisions that shape the schema and the logging, so they are settled during scoping rather than written up afterwards.
Payments split by business model. Card checkout is Stripe territory. Recurring billing frequently is not: Direct Debit through Bacs, usually via GoCardless, remains the expected way to collect a regular fee from a UK customer, and it behaves differently from a card. Mandates take days to set up, payments fail days after submission rather than instantly, and the product has to represent an in-flight payment honestly instead of assuming success.
VAT adds requirements beyond a rate. Making Tax Digital means returns are filed from software, so invoice records need to be complete and exportable in a form an accountant or bookkeeping tool accepts. Zero-rated and exempt categories are specified per business rather than assumed.
Hosting is commonly pinned to UK or EU regions, and sub-processors are listed because customers ask for that list.
Software Modernization in United Kingdom
Modernisation enquiries from the UK often involve an application that still works but is now hard to change or host — an ageing PHP stack, an unsupported framework version, a server nobody wants to touch. Work starts by pinning current behaviour down in tests, because the business rules usually exist only in the code. Migration is staged so the old and new systems can run side by side during cutover.
