ERPNext Migration in Ireland
Switching ledgers is where most ERP projects either earn trust or lose it. We move customers, suppliers, items, open invoices, stock and balances from Sage, QuickBooks, Xero, Excel or an older ERP into ERPNext, reconcile every control total with your accountant and time the cut-over around your VAT calendar, so the first VAT3 from ERPNext is one you can trust.

What moves, what stays and why
Not everything in an old system should come across. Copying every historic transaction into ERPNext is slow, prone to error and rarely useful. Our usual approach brings over active masters, open documents and balances at a cut-over date, plus summarised monthly balances for comparison reporting, while the old system stays available read-only for history, audits and any questions from Revenue.
The source matters too. Xero and QuickBooks Online export cleanly through their reports and APIs. Sage desktop data needs careful extraction, often with duplicate customers and old stock codes to tidy. Spreadsheets need the most work, because every sheet has its own logic. We profile the data first, agree a cleansing list with your team and only then start loading anything.
From first record to the finished report
One open-source system, so each step feeds the next without re-keying.
How we handle ERPNext data migration
Data profiling first
Before mapping anything we analyse your exports for duplicates, missing VAT numbers, inactive items, odd units of measure and negative stock, then give you a short cleansing list ranked by impact.
Field mapping workbook
A shared workbook maps every source field to its ERPNext target, including customer groups, item groups, tax templates, payment terms and price lists, so your team can see and approve each decision.
Repeatable trial loads
Imports are scripted so they can run again from scratch. We perform several trial loads on staging, each followed by checks, until the numbers match without any manual fixes in between.
Accountant reconciliation sign-off
Debtor and creditor ageing, stock quantity and value, bank balances and the trial balance are compared line by line with the source, and your accountant signs a reconciliation pack before cut-over.
Spreadsheet consolidation into masters
Businesses running on Excel get price lists, stock sheets and customer lists merged into single clean masters, with one named owner responsible for each data set once ERPNext is live.
Read-only archive plan
We agree how the old system stays reachable after cut-over, whether a retained licence, an export to a searchable archive or a reporting copy, so history is there when someone asks for it.
ERPNext and the Frappe apps we implement
One open-source platform, one database, no per-user licence fees.
Irish points to protect during migration
| Topic | The Irish rule | What we set up |
|---|---|---|
| Filed VAT periods | VAT3 returns already filed on ROS cover past periods, and those figures should not be recalculated by a new system after the event. | We set the cut-over at the start of a VAT period, load prior figures as summary balances only and lock those periods in ERPNext so nobody posts into them by accident. |
| Open invoices and VAT | Each open sales and purchase invoice was issued at a specific Irish rate of 23%, 13.5%, 9%, 4.8% or 0%, and that VAT is already in a return. | Open items load as opening invoices for their gross amounts against a temporary opening account, so VAT is not counted twice, with the original VAT detail kept in a reference field. |
| Payroll history | Under PAYE Modernisation, every past pay run has already been reported to Revenue in real time from your existing Irish payroll software. | Payroll history stays in BrightPay, Sage Payroll or whichever Irish package you use. We move only employee masters, leave balances and cost centre mapping into Frappe HR. |
| Personal data | GDPR and the Data Protection Act 2018 expect personal data to be kept only for as long as it is needed, with the Data Protection Commission as regulator. | Migration is a chance to drop dormant contacts and stale leads. We agree what to leave behind, move files over encrypted connections and delete working copies after sign-off. |
We configure the system and check it against your accountant’s figures; we are not tax advisers, and your accountant files the returns. Last reviewed 24 October 2026.
Our migration method
Source assessment
We inspect the current system, its version, export options and data volumes, and agree with you a cut-over date that lands at the start of a VAT period.
Mapping and cleansing
Your team fixes duplicates and gaps at source, guided by our cleansing list, while we complete the mapping workbook and write and test the import scripts.
Trial loads
Each trial load into staging is followed by checks of counts and totals. Differences are traced to a cause and fixed in the scripts, not patched by hand.
Reconciliation pack
Ageing reports, stock valuation, bank balances and the trial balance are matched with the source and documented in a pack your accountant reviews and signs.
Cut-over weekend
Trading in the old system stops, final balances are extracted and loaded, checks are repeated and users start in ERPNext on the first working day of the period.
