BigQuery Migration in Northampton
Migrating Northampton organisations onto BigQuery, where the assumption that costs most is that standard SQL simply ports. Dialects differ in date handling, type coercion, window behaviour and a hundred smaller details — and the queries that fail outright are less trouble than the ones that run and return a slightly different answer.
Why this comes up
The problem
The queries were translated, they all execute, and one report's totals differ from the old system by two per cent.
What you get
What we deliver
- Dialect differences catalogued against the constructs your queries actually use
- Results compared row by row rather than checked for successful execution
- Data model revisited, since a columnar store rewards different structures
- Nested and repeated fields used where they suit the data better than joins
- Partitioning and clustering designed during migration rather than retrofitted
- Parallel running until reconciliation across a full reporting cycle is clean

Working in Northampton
East Midlands
Northampton sits at the centre of the UK's distribution network, and warehousing and logistics operators here tend to need stock, routing and fulfilment systems that talk to whatever the client's customers already use.
Warehousing and distribution work leads here: stock accuracy, routing, proof of delivery, and portals that let customers see their own inventory without phoning in.

BigQuery Migration in Northampton — common questions
- Which SQL differences cause the most trouble?
- Date and timestamp handling, implicit type conversion and null behaviour in aggregates. These rarely produce errors — they produce results that are quietly different, which is why comparing output matters more than confirming that everything ran.
- Should the data model change?
- Frequently, yes. Structures designed for a row-based system with expensive joins may be better expressed with nested fields here, and carrying the old model across means the platform's strengths go unused while its cost model applies regardless.
- How thoroughly should results be compared?
- To the row where volume permits, and to aggregate totals with distribution checks where it does not. A summary comparison passes when a small subset differs, and a small subset differing is exactly the failure that surfaces months later in a board pack.
- How long should both systems run?
- Through at least one complete reporting cycle with reconciliation at each stage. That period is what converts confidence from an assertion into evidence, and it gives the teams who depend on the numbers time to raise discrepancies while there is still something to compare against.
- Do you work with businesses across Northamptonshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East Midlands, including Northampton and the surrounding Northamptonshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Northampton businesses do you usually work with?
- Warehousing and distribution work leads here: stock accuracy, routing, proof of delivery, and portals that let customers see their own inventory without phoning in. Beyond that we work across Logistics & Distribution, Footwear & Leather, Motorsport, Financial Services and Retail.
- Do you cover the areas around Northampton?
- Yes — we work throughout East Midlands, including Milton Keynes, Leicester, Coventry, Cambridge. Northampton is an urban area of roughly 245,000+, and we take on work across the wider Northamptonshire region rather than the city boundary alone.
