WHY NOW

1 version

Sage now supports only the current Sage 50 release

Sage 50 moved to subscription-only licensing, and support for version 2024 ended on March 4, 2026. Retired versions lose tax updates, bank feeds and payment add-ons. If you're renewing anyway, moving the company files to NetSuite gives you one multi-subsidiary system instead of another annual upgrade.

What to plan for on Prophet 21
The Sage 50 details that make or break a migration
These come from real NS90 Sage 50 projects. Each is already built into our standard Sage 50 mapping, so you don’t discover it at UAT.

Access is the critical path

Sage 50 often runs on a hosted server or a single office PC. We arrange VM access, the ODBC driver and permission to run read-only scripts at kickoff, because that's what decides the timeline.

One file per company and year

Sage 50 has no multi-company structure, so groups end up with a file per entity and sometimes per fiscal year. We scope by file count and merge them into NetSuite subsidiaries in one pass.

One journal table, many transaction types

Invoices, receipts, bills and journals all live in the same journal tables. We separate them by module and journal type, then confirm the counts with you before loading.

Open-item filters you sign off

Open invoices and bills are defined by amount less amount paid, and the filter differs by transaction type. We test each filter against your aging reports before anything loads.

Customers and vendors share a list

A Sage 50 name can be both a customer and a vendor. We decide up front which records become customers, vendors or both, and set their subsidiary relationships.

Data that lives outside Sage

Items, projects or purchase orders often sit in other tools. We confirm in discovery what Sage 50 actually holds, so we don't build mappings for data that isn't there.

Amounts reconciled before go-live

Every loaded document is reconciled to source totals, so a scale or decimal issue is caught before cutover, not after.

Departments hidden in account numbers

Masked account IDs often carry departments. We split them into NetSuite accounts plus department or location.

Entity per subsidiary, plus exceptions

Vendors and customers used by more than one company get secondary subsidiaries, so payments never fail on a subsidiary mismatch.
