Client Onboarding & Data Migration Platform
One process from closed-won to go-live.

- 10,000+onboardings and migrations delivered
- 2,500+locations migrated in one project
- 50+engineering projects on source systems

What onboarding and data migration look like when they run as one process. The same platform your customers work in.

Where Onboarding Breaks
& How We Fix It
Slow onboarding holds your growth back: process chaos, data that arrives in the wrong shape, clients who stop responding. All three share one root cause: nobody owns the path from signature to go-live.
Three Solutions.
One Seamless Experience.
One engine underneath all three — that is why they work as one process, not as three projects.

Each one cuts over when their own data checks out, not on a fixed wave date
Audit trail per acquisition
What moved, when, and approved by whom, on file at cutover

Who runs it: you, us, or both
The same platform, three ways to deliver it. The service scales with how stubborn your data is, not with every deal you close.
Self-Driving
A platform licence and a one-off setup. Your team runs the onboardings.
Fits when the sources are standard and the capacity is yours.
Engineer-Supported
Our migration engineers take on the sources that fight back.
Fits legacy databases and logic nobody documented.
Co-Piloted
Platform plus service until the whole customer base has moved.
Fits acquired customer bases and a deadline somebody else set.
The question your customer's auditor will ask
When the auditor asks about data validation: what is the basis? Where is the result? Where is it frozen? Where can I compare it?
Where is the validation documented?
Every run is logged with timestamp, operator and result: which records were checked, and against which target value.
Where is the state frozen?
A snapshot per test import, with an immutable reference. You can say which state was frozen, and when.
Who migrated what, and when?
An audit trail across every transformation step, time-stamped and immutable on S3 Object Lock for ten years.

Micromerce works with the tools your team already uses – and keeps everything in sync.
All our solutions can be integrated into various existing systems on the market. In this way we can adapt our solution to all your needs.
From the first call to your team running it.
In this meeting, we aim to understand your current situation and challenges.
Duration: 30 min
After gaining an initial understanding of your challenges, we will conduct a structured analysis session together, completing a Customer Onboarding Canvas. A few days later, we will present the results along with a detailed proposal and offer.
Duration: Two 1-hour sessions
Depending on complexity, configuring the Onboarding Back Office and Portal takes 1–5 days. For setups without external integrations, it requires just a few clicks.
Duration: 1-5 days
Once the platform is set up, onboarding managers and migration developers (if handling transformations in-house) can begin using it, supported by thorough training sessions.
Duration: 2 hours onboarding manager, 1 day migration devs

FAQs
We offer three delivery shapes. Self-Driving: your team runs the platform after an initial setup. Engineer-Supported: our migration engineers take on complex sources. Co-Piloted: we run the queue together with your team, customer by customer. In every shape the goal is the same — your team ends up able to run it.
Micromerce solutions provide streamlined tools and intuitive features, enabling your team to get started immediately. However, we recommend a 2-hour training for onboarding managers and a one-day session for migration developers.
Partly. The platform itself runs in the cloud, but the migration runner can live in your own AWS account (Bring Your Own Cloud) — so your data never leaves your environment.
The Micromerce migration solution is available anytime and anywhere at https://application.micromerce.com.
The Micromerce solutions can be easily integrated into your existing system landscape. We are constantly expanding our integrations and are experts in developing flows across system boundaries.
