Client Onboarding & Data Migration Platform
One process from closed-won to go-live.
Data migration included.
Most platforms stop where the data starts. Ours moves it, validates it in your system, and keeps the proof, for one new customer or an entire acquired base.
- 10,000+onboardings and migrations delivered
- 2,500+locations migrated in one project
- 50+engineering projects on complex sources
- 20+data sources connected out of the box


Where onboarding breaks
& how we fix it
Onboarding stalls in the same four places, and nobody owns the path from signature to go-live:
- It depends on one person. When they are out, nothing moves.
- Nobody knows where it is stuck or who is on it.
- Every export arrives in a different shape.
- Nobody can say whether everything arrived.
Three ways in.
One process.
One engine underneath all three, so they run as one process instead of three projects.

Migrate Existing Clients
With our M&A Migration Suite
One engine, several sources
Acquired source systems run through the same engine

Audit trail per acquisition
What moved, when, and approved by whom, on file at cutover
See it in two minutes
What onboarding and data migration look like when they run as one process. The same platform your customers work in.

Did everything arrive, and is it right?
When the auditor asks about data validation: what is the basis? Where is the result? Where is it frozen? Where can I compare it?
Did every record arrive?
Records are counted per data type and location, source against target. Each location gets a go or a no-go, with the deviation named.
Do the numbers still add up?
Counts and sums are compared between source and target in every test run, so a difference shows up before anyone cuts over.
Can you prove it later?
Every run is logged with time, operator and result. Each test import is a frozen snapshot, immutable on S3 Object Lock for ten years.
Real impact from the first onboarding
The numbers below come from onboardings we run ourselves, not from a model.
Up to 50%
reduction in onboarding time
3X
the onboardings per FTE
75%
fewer manual steps for onboarders
The European market leader in gym software faced similar challenges and was able to achieve the following results by working with Micromerce:
Micromerce helped us accelerate our customer onboarding by up to 50% and significantly improve data migration quality. Their exceptional collaboration and dedication to always going the extra mile have enabled us to achieve our goals efficiently and effectively.

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.
20+ data sources
without custom code
Databases, files and APIs out of the box: MS SQL, Oracle, PostgreSQL, Excel, CSV, S3.
The tools your team already works in connect the same way.
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 platform and the client 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.
