Garbage in, garbage forever
Importing messy data into a clean new system just moves the mess somewhere more expensive.
CRM & integrations
Move to the new system without leaving the good data behind.
We map, clean and move your records between systems with test runs and a rollback plan, so the switch is a non-event for your team and your customers.

This is for you if
- You are replacing your CRM, shop, or an old in-house system.
- Years of data are duplicated, inconsistent or half-empty.
- You are nervous that a switch will lose customer history.
What it costs you now
What the problem really costs.
Fields do not match
Old and new systems describe a customer differently, so naive imports lose meaning.
There is no way back
A one-shot import with no rollback turns a mistake into a crisis.
How it works
How we build it, step by step.
Four stages, each with something you can see and approve before we move on.
-
Audit what you have
Volumes, quality, duplicates and the fields that actually matter, with an honest estimate of the clean-up.
-
Design the mapping
Every field from the old system mapped to the new, with rules for the awkward cases.
-
Test migrations until they are boring
Repeated trial runs into a test system, checked against the source, until the numbers match.
-
Cut over with a rollback plan
A planned switch-over window, verification checks and a tested way back if anything is wrong.
What you walk away with
Everything is yours.
Source files, documentation, accounts and keys transfer to you. Ongoing support is a choice, never a dependency.
- Data audit and clean-up report
- Field mapping specification
- Test migrations with reconciliation
- Production cut-over
- Rollback plan
- Archive of the source data
Best fit
Works especially well for.
Straight answers
Data migration and clean-up: your questions, answered.
Will we lose any history?
Not if it is mapped properly. We reconcile record counts and sample records between old and new, and keep a full archive of the source data.
Can you migrate from a system that is being shut down?
Yes, often urgently. We start by securing a complete export so the timeline pressure does not put the data at risk.
How do you handle duplicates?
We use matching rules you approve, merge the obvious ones automatically, and list the uncertain ones for a person to decide.
Do we have to stop working during the cut-over?
Usually for a short, planned window — often an evening or weekend. We agree it in advance and keep it as brief as possible.
