Cofactu vs Sage 50 — no SQL Server, no partner, no 45-day notice.
Sage 50 is robust but carries the operational friction of a 40-year-old desktop product: local SQL Server, a cert per user per machine, 45-day phone-only cancellation, and renewal as expensive as a new purchase. Comparison with real quotes from the Sage Community Hub (May 2026).
What Sage 50 users say in 2026
Quotes and recurring patterns from Trustpilot, Capterra, and the App Store. We don't edit or cherry-pick the harshest ones — these are the most repeated complaints in verified reviews, with a link to the source.
"We've been on Sage50 for 2 years… it constantly throws errors, but the most painful part is they give you no solution, they don't answer the phone, they don't reply to emails."
Sage Community Hub · TOTAL DISAPPOINTMENT
"The migration didn't bring over all the expense and revenue subaccounts… it put a generic 600 for all expenses and a 700 for all revenue."
Sage Community Hub · FacturaPlus migration
"Sage is slow and laggy. It forces way more mouse clicks, enters, and countless screens, which slows the work down a lot."
Sage Community Hub · SAGE IS SLOW
"You can cancel the Sage 50 subscription at any time, but you need to communicate the cancellation with 45 days notice before your annual renewal date."

| Sage 50 → Cofactu importer preserving subaccounts Sage Community Hub: "it put a generic 600 for expenses and 700 for revenue" | Dry-run with a preview of mismatches before commit | Plus → Sage migration loses subaccounts (600/700) |

Assisted migration from Sage 50
The pain of migrating TO Sage is well documented (lost subaccounts, unbalanced totals). Migrating FROM Sage with us is the opposite:
- Sage 50 CSV/XML importer — clients, suppliers, products, PGC journal entries, historical invoices. Preserves subaccounts as-is.
- Dry-run with preview — runs the import in a sandbox, shows you mismatches before commit. No surprises.
- Free post-migration audit — we compare totals by fiscal year between your Sage export and Cofactu, and report any discrepancies.
- 30 days free + no lock-in — if you'd rather stay on Sage afterward, take your data as a ZIP and we part ways. Zero exit cost.
