01 / WHAT WE DO

Good data starts
with the right groundwork.

A one-off file fix or a more involved migration.
One defined problem. A clear deliverable.

01

Clean &
standardise.

Fix inconsistent formats, identify duplicates and flag missing information. Keep the meaning. Remove the mess.

03

Validate &
reconcile.

Compare source and target data. Check record counts, key fields and agreed rules — with exceptions clearly documented.

Migration checksQuality reports

Need a recurring check? We can scope a repeatable workflow — without replacing your existing systems.

02 / THE HANDOVER

Not just a cleaner file.
A result you can check.

You should know what changed, what was checked and what still needs a decision. That’s why the handover matters as much as the transformation.

Data handling agreed upfrontTools, access and retention are part of the scope.

Unknowns stay visibleNo silent guessing of missing business information.

05 / A FEW ANSWERS

Before we
get started.

Clear expectations make
better projects.

Can you help with just one spreadsheet?

Yes. A single Excel or CSV file can be a complete project. Describe the problem and the result you need; the scope and price are agreed before work starts.

What kind of data can you work with?

Excel and CSV files, product and customer records, import templates, and exports from business databases. For database-specific work, we first agree on the source, permissions and checks. A sample helps establish feasibility before any commitment.

Will you need access to our live systems?

Not for every project. Many file-cleaning and comparison tasks can be scoped using authorised exports. Production access, when genuinely needed, is a separate decision — never an assumed requirement.

How do you handle confidential data and AI?

We agree on permitted tools, access and retention before receiving production data. AI-assisted tools may support appropriate tasks, but client data is not to be submitted to external AI services without explicit agreement. Start with anonymised examples, not sensitive files.

How are pricing and turnaround determined?

By the structure of your files, the required transformations and the validation effort — not just the row count. You receive a scoped quote and an agreed delivery plan. Ongoing checks or changes beyond the scope are quoted separately.

Will the output be guaranteed to import?

We validate against the target template and rules you provide. A successful test in the target system is a separate acceptance step when access is available. Unresolved data issues are reported rather than hidden or guessed.
