Your systems, connected

Moving systems? We move the data so nothing breaks.

We connect to your system, extract and structure your data, and hand you a working result. You give us a login — not your team’s time.

◆ You provide access. We do the rest.

How do I migrate business data from an old system to a new one without losing it?

You migrate business data from an old system to a new one without losing it by extracting the old system in full before touching the new one, reconciling record counts and totals between the two, and keeping the old system readable until the reconciliation passes. Most migration losses are not dramatic failures; they are fields quietly dropped in mapping and noticed months later, when the source is already gone.

A migration is three jobs that get confused with each other: getting the data out, deciding what it means in the new system, and proving nothing was lost. The third is the one that is usually skipped. We extract to a structured intermediate you can inspect, map against it in the open, and reconcile counts and financial totals on both sides before anyone commits to a cutover date.

Meet the Gateway

Getting your data out of system is step one. The real win is one server that manages all your automations — the Gateway. It sits between system and everything else, decides which system receives which data, and keeps an audited record of every transfer. Not a tangle of fragile point-to-point links. One place you control.

Every system connects to the Gateway — not to each other. Data flows both ways, on a single audited path, and only where your rules allow.

Routes every transferOne path in and out — not a dozen fragile links between pairs of systems.
Controls who gets whatRules decide which system sees which data. Nothing moves that you didn’t allow.
Audits everythingA record of every transfer — what moved, where, and when. Provable, not assumed.

Connect one system today, or connect them all — the Gateway grows with you. Nothing is locked in, and everything runs on access you grant and can revoke.

How it works

Step 1

You grant read-only access

A single login. We hold it in an encrypted vault and remove it when we’re done.

Step 2

We extract and build

We pull your data — items, pricing, orders, attachments — structure it, and build what you need.

Step 3

You get a working system

A catalogue, a feed, a hub — yours to own, on your own cloud account. No dependency on us.

“Give a stranger a login to my business?” — fair. Here’s how we handle it.

  • ✓Read-only access. We extract; we don’t change anything in your system.
  • ✓Credentials in an encrypted vault, never in an email or a spreadsheet.
  • ✓Access removed at the end. We take our access out of your account when the work is done.
  • ✓A signed agreement before anything is touched. You see a plan and a price first.
  • ✓Your data stays yours, in your own cloud account, exportable at any time.
☁ Cloud-hosted Containerized — runs on Google Cloud or AWS, in your own account, not ours.

Questions we get asked

Can you migrate from a system that is no longer supported?
Usually yes. If the data is reachable through an API, a database read or even a scheduled export, it can be extracted. Legacy systems are the common case, not the exception.
How do we know nothing was lost?
Record counts and control totals are reconciled between source and destination before cutover, and the intermediate extract stays available afterwards so any later question can be answered from it.
Do we have to stop trading during the migration?
No. The extraction is read-only and runs against the live system without interrupting it. Only the cutover itself needs a planned window.
What happens to the old system afterwards?
Keep it readable until reconciliation passes and the first full period closes cleanly in the new system. Decommissioning early is how losses become permanent.
