Keep what works. Replace what doesn’t. Connect the rest.
Most businesses don’t need a big-bang rewrite. We find what actually needs to go, replace it in stages with a way back at every step, and connect your ERP, accounting and warehouse so data is entered once.
Problems we fix
Sound familiar?
The system nobody dares touch
Replaced piece by piece behind the scenes, so people keep working while it changes.
Spreadsheets doing a system’s job
Turned into a proper tool, with permissions, history and checks.
The same data typed twice
Systems connected so orders, stock, invoices and customers flow between them.
Reports nobody trusts
One source for each number, and reports built on it.
How we modernise
Change the system without stopping the business.
Map what you have
Every system, who uses it, what depends on it, and where the data disagrees.
Decide: keep, replace or connect
A written recommendation for each system, with the reasons — before anyone sells you a rebuild.
Replace in stages
The new system takes over one piece at a time, running alongside the old one until it proves itself.
Always a way back
Every step can be reversed, and data is moved with checks that prove nothing was lost.
Integration
Integrations that survive real life.
We connect ERPs, accounting packages, warehouse and e-commerce systems through their APIs or, where there is none, through a connector built for the job. Our integrations retry safely, record what they did and alert someone when they fail.
In our own product, yarn.ai, we are building connectors for Microsoft Dynamics 365 Business Central and Tally.

What comes next
Ready for AI agents once the data flows.
Connected, trustworthy systems are what AI agents need to be useful. Once the plumbing is in place, an agent can read across it and prepare work — matches, replies, reports — for your team to approve.

Questions
Questions about modernising
Do we have to replace our ERP?
Rarely. If it does its core job, we keep it and build around it — connecting it to your other systems and adding the tools it lacks.
How do you move data without losing any?
In rehearsed steps, with checks that compare counts and totals between the old and new systems, and a way back if anything doesn’t match.
Can you work with Business Central or Tally?
Yes. We are building connectors for both in our own product, and we work with any system that has an API or a database we can reach.
What happens to the old system?
It keeps running until the new one has taken over each part and proved itself. Then it is retired on a date you agree, with its data archived.
