Stay on BILL when their win still matches the job. Look at ficary when you want practice management and books on one platform. Nominative comparison — not a partnership and not a client story.
Stay on BILL when
Choose BILL when you must pay vendors on their network this month and you will keep the ledger elsewhere.
A vendor network, ACH and check pay, approval workflows, and an accountant program that resells client entities. If paying strangers this week is the job, they already sell that.
Look at ficary when
Choose ficary when uncoded bills, a missing W-9, or as-of payables have to live on the same books as the rest of the month.
The books. A paid bill that leaves August open is still a pile. As-of AP, leftovers, and a fee cap live here — not in a sync back to QuickBooks.
