Micromerce timeline: onboardings and feature releases on one timeline

For you if an acquisition has to move onto your platform.

Looking for onboarding new customers or getting data out of a legacy system?

Where acquisitions lose momentum

Two systems, one customer base. Every month of running both costs twice.

The acquired data is worse than the deal assumed. Now it is your problem.

The migration runs on hand-built jobs. One person knows how, and they are busy.

Customers notice transitions. The ones you just bought notice them most.

Post-merger

Where the value of an acquisition is actually realized

Between signing and realized value sits the line item nobody priced: moving thousands of customer datasets out of the acquired platform without losing the customers themselves.

Where the value of an acquisition is actually realizedTwo curves over time: planned value rises steadily after close, while actual value dips during integration and only recovers afterwards. The area between them is the value lost in the customer migration.Planned valueActual valueValue at riskValuerealizedTimePre-closeDeal closeIntegration
Value loss typically occurs during customer migration and platform consolidation.

FAQs

It depends on the size of the acquired customer base and data complexity. A pilot cohort usually migrates within 4–6 weeks. Migrating an acquired customer base of thousands typically takes 3–6 months — customer by customer through one queue, not a big-bang cutover.

That’s common. Most teams hit a wall when manual scripts can’t scale beyond the first 50–100 customers. Micromerce picks up where scripts break down — with repeatable templates, automated validation, and batch processing.

Yes. We specialize in multi-entity customers, nested hierarchies, and industry-specific formats like ERP structures. Our AI mapping layer learns from every migration, so complex schemas get easier over time.

No. Micromerce integrates into your existing stack. If you already use tools for project management or customer communication, they stay. We handle the data migration layer those tools weren’t built for.

Every customer gets a branded portal where they can track progress, upload data, and complete tasks. Your team stays in control — without answering “What’s the status?” emails.

Mostly B2B SaaS companies that acquired a competitor and need to sunset the legacy platform. We’ve run 10,000+ onboardings and migrations across industries — from fintech to HR tech to logistics.
