Accounting System Migration

Support moving from spreadsheets or legacy systems to modern accounting platforms.

Overview

How we help with Accounting System Migration

Migrations go wrong in predictable ways: opening balances that do not agree, VAT history that will not reconcile, and a period where nobody trusts either system. Planning prevents all three.

We plan the migration around a clean cut-off date, agree opening balances back to your last set of accounts, transfer open sales and purchase items with their full detail, and carry across the transaction history you need for comparison and VAT purposes.

After go-live we run a parallel check on the first period so any difference is found while it is still small and traceable.

FAQs

Accounting System Migration — common questions

Can we keep our historic data?

Yes — transaction history can normally be brought across, though how far back is worth doing depends on your VAT and reporting requirements. We agree the scope before starting.

When is the best time to migrate?

The start of a financial year is cleanest, and the start of a VAT quarter is the next best option. Mid-period migrations are possible but need more reconciliation work.

How is your fee worked out?

Fixed fee, agreed before we start. Pricing depends on the size and complexity of your business, so get in touch for a free, no-obligation quote.

Can you help if we're switching from another accountant?

Yes. We handle professional clearance with your previous accountant and update the agent authorisations with HMRC and Companies House, so you don't have to manage the handover.
