Busy to ERPNext
migration, reconciled.

It varies with data volume, module scope and customisation, and we would rather scope it than quote a week count we cannot stand behind. An accounting-only switch with clean masters moves quickly; a multi-branch setup with inventory, custom print formats and integrations takes longer. Reconciliation and data cleanup consistently consume more time than the technical import.

Keep Busy accessible as a read-only archive, but do not post live transactions in both. Dual posting is how books diverge and how a migration turns into a reconciliation project. Pick a single cut-over date, reconcile opening balances in ERPNext, and from that date record everything in ERPNext only.

Three things, reliably: duplicate ledgers that were never rationalised, GST heads mapped to the wrong parent so returns come out wrong, and an opening balance that refuses to tie out. All three are cheap to prevent in the mapping stage and expensive to unpick after go-live, which is why the reconciliation gate sits before the cut-over date, not after it.

Yes. Your GSTINs, HSN/SAC codes on items and tax templates are configured in ERPNext before go-live, and e-invoicing and e-way bills run through the free India Compliance app. Returns for periods filed from Busy stay where they were filed; ERPNext produces returns from the first live transaction after cut-over.

No, and nothing about a migration deletes it. Exporting data from Busy leaves Busy exactly as it was, and you keep it as a read-only archive. What moves into ERPNext is masters, open items and opening balances — not years of closed transactions. Closed periods stay closed where they were filed, and ERPNext produces fresh reports and GST returns from your first live transaction after cut-over.

ERPNext is open source, so there is no licence fee and no per-user charge — your spend is implementation, hosting and optional support, and it does not grow when you add people. We publish the cost drivers rather than a single number, because scope, entity count and customisation genuinely move it.

Yes. ERPNext is deployed on infrastructure you control — source, data and runtime stay with you. You can take the whole instance elsewhere, or run it yourself, without asking us. That is the point of the stack, and it is the thing a licence never gives you.

We fix a cut-over date once a test load on staging ties out to your Busy trial balance. On that date Busy stops taking new entries, the final open items and balances are loaded and checked, and every transaction from then on is posted in ERPNext only. The rollback criteria and who signs off are agreed in writing beforehand.

Key users are trained before cut-over, and we can sit alongside your team for the first period-end close in ERPNext. After that you can keep us on a support plan or run it with your own team.
