NetSuite Migration in London
Moving London organisations onto NetSuite, where several structural choices harden the moment real data arrives. Accounting periods, subsidiary structure and item types are difficult or impossible to change once transactions post against them — so a migration is largely a sequence of decisions made before anybody can see the consequences.
Why this comes up
The problem
Items were set up as the wrong type during the import, and correcting them now means recreating them and their history.
What you get
What we deliver
- Structural decisions made deliberately, with their permanence made explicit
- Opening balances agreed with finance rather than derived from an extract
- Records loaded in dependency order with relationships verified afterwards
- External identifiers retained so the old system can still be reconciled against
- Historic transactions assessed against what will genuinely be used
- A full-scale rehearsal into a sandbox before the live cutover

Working in London
London
London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates.

NetSuite Migration in London — common questions
- Which decisions are effectively permanent?
- Subsidiary structure, accounting period setup and item type are the ones most often regretted. They are ordinary-looking choices during configuration and become embedded in every transaction, at which point changing them means recreating records and their history.
- How much history should we bring?
- Balances and the transactional detail people genuinely reference — commonly one or two years. Full history is expensive to migrate and validate, and the occasional lookup is usually served better by keeping the old system readable for a period.
- Why keep external identifiers?
- Because you will need to reconcile. Holding the legacy reference on each record lets finance tie a NetSuite transaction back to the source system during the first year-end, which is when every discrepancy gets examined properly for the first time.
- Is a sandbox rehearsal necessary?
- Yes, at full volume. Imports fail on validation rules, on relationships and on data quality nobody sampled, and a rehearsal converts the cutover from a discovery exercise into a repeat of something that has already worked once.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
