Migrating Accounting Data Out of a Legacy Precast ERP: Chart of Accounts, Open AP/AR, and History

When a precast plant runs its books inside its ERP — as producers on Titan 3000 do — changing systems means moving the accounting too. That's the part controllers worry about most, and rightly so. Here's how to move financial data out of a legacy precast ERP without breaking the close.

Decide: Move the Books, or Keep Them Separate?

The first decision isn't technical. Some plants want production and accounting in one system again. Others — especially plants owned by a group with a corporate ledger — prefer to run the plant in a precast ERP and post to an existing QuickBooks, Sage, NetSuite, SAP, or Oracle instance. Either works; the migration scope is very different, so settle it first.

Clean Up the Chart of Accounts First

Legacy charts of accounts grow by accretion: duplicate accounts, retired departments, one-off accounts nobody remembers opening. A migration is the one moment you can fix that cheaply. Map the old accounts onto a clean, standardized chart, and keep the mapping table — auditors and your own team will want to trace old balances to new accounts later.

Carry Over What's Open

The critical data at cutover is whatever is still in flight:

• Open AR — every unpaid invoice with customer, amount, due date, and any retention.
• Open AP — unpaid vendor bills, so nothing is paid twice or missed.
• Open purchase orders — committed material spend on active jobs.
• Opening balances — a trial balance as of the cutover date, reconciled to the old system.

Reconcile each of these to the legacy system at cutover. If open AR in the new system doesn't tie to the old aging report to the penny, stop and fix the mapping before anyone sends an invoice.

How Much History Should You Move?

Not all of it needs to be live in the new system. A common pattern: migrate the current fiscal year in detail for comparisons, carry prior years as summarized balances, and keep a read-only archive of the legacy database for anything older. Job and customer history is often worth bringing over in detail, because it drives estimating and reorders.

Time the Cutover to a Close

Cut over at a month-end — ideally a quarter-end — after the old system's books are closed for the period. Run the new system in parallel for at least one close cycle beforehand so the accounting team has already produced a full set of statements in it before it becomes the system of record.

Don't Forget Payroll and Job Costing

Payroll setup and labor distribution feed job costing. Map earnings codes and departments along with the GL so labor lands on the right jobs from day one. In CastLogic, payroll can run through our HR module or through integrations with platforms like Paylocity and Rippling.

Frequently Asked Questions

Can accounting data be migrated out of Titan 3000?

Yes. Because Titan 3000 is a full ERP, a migration can include the chart of accounts, opening balances, open AP and AR, and purchase orders. The legacy chart is typically mapped to a clean, standardized general ledger in the new system.

Should I migrate all historical accounting transactions?

Usually not. A common approach is to migrate the current fiscal year in detail, carry prior years as summarized balances, and keep a read-only archive of the legacy system for older records.

When is the best time to cut over accounting to a new ERP?

At a month-end or quarter-end, after the legacy books are closed for the period, and after running the new system in parallel for at least one full close cycle.

Can I keep my current accounting software and still replace my precast ERP?

Yes. Many producers run a precast ERP like CastLogic as the operational system and integrate with QuickBooks, Sage, NetSuite, SAP, or Oracle through open APIs instead of moving the books.
