Map a native export if you can get one. Clients first, then work, then time. Confirm counts. Do not re-key a ficary workbook.
Nominative guide, not a partnership. No API keys, no endpoint list, no importer internals. Those stay behind login for clients. Tax prep stays last. ficary has not earned SOC 2, ISO 27001, or a HIPAA attestation.
The move
Export clients, projects, and time if the firm can produce a file.
Map clients first, then work, then time on Practice → Import.
Opening WIP keeps the date it was incurred.
Reconnect email. Do not import mail.
Stay on Deltek Maconomy when
Choose Maconomy when the firm is a professional-services ERP shop and that is already the operating system.
Move when
Choose ficary when a CPA firm needs as-of WIP and books, not a Deltek implementation.
