For ERP platforms

Migrate an ERP without breaking the ledger

Vern imports items, bills of material, stock positions and open transactions from a legacy ERP — reconciled and validated before it becomes your customer’s opening balance.

Why Vern

Balances that reconcile, and a cutover your customer can sign off on.

What breaks in a manual ERP move — and what Vern does about it.

Everything references everything

Items reference suppliers, BOMs reference items, transactions reference all three. Import them in the wrong order and every foreign key fails at once.

Units and precision drift

Cases versus eaches, four decimal places versus two, a cost field that turns out to include freight. Small differences compound across a stock ledger.

Open transactions are the hard part

Part-received purchase orders and part-shipped sales orders have to arrive mid-flight, in a state your product can actually continue from.

The cutover window is short

The ledger has to reconcile between the last day on the old system and the first day on yours, and there is no second attempt.

How it works here

What Vern does differently on this data

Relationships inferred, then confirmed

The agent works out how items, suppliers and transactions reference each other across the export — and imports them in dependency order rather than file order.

Your mapping rules, not ours

Split names, normalise formats, recalculate derived fields, merge records — described in plain English and saved as a recipe you can read and re-run.

Unit and precision normalisation

Units of measure and decimal precision are converted explicitly, and any conversion that would lose precision is raised as a question rather than rounded away.

Self-healing imports

After a run, the agent inspects every cell that failed validation, fixes what it can in the recipe, and re-runs. What it can’t fix is reported with an exact count, never silently dropped.

Reconciliation before go-live

Source fill-rates and totals are compared against the imported result, so a field that arrived empty is caught before your customer finds it.

A full audit trail

Every clarification, mapping choice and automated fix is logged with a before and after, attributed to a person or the agent, all the way back to the original upload.

What moves

What comes across, and what Vern adds on the way

Items, BOMs & routings: Imported in dependency order so nothing lands orphaned.
Suppliers & customers: Deduplicated and matched across the files they appear in.
Stock on hand & valuations: Units and precision normalised, with the totals reconciled.
Open purchase & sales orders: Part-fulfilled orders arrive in a state you can continue from.

Extractors

41 connectors for this space, and the agent writes the rest

Connect a source once and every customer you onboard off it reuses the same connection and everything Vern already learned about it.
