How to think about this comparison
Ignition (formerly Practice Ignition) is a proposal and billing automation platform popular with accounting firms, bookkeepers, and professional services businesses. It handles engagement letters, recurring billing, automatic payment collection at proposal acceptance, and some follow-up reminders. Its primary value is upstream of collections — getting payment details captured at the proposal stage so invoices don't require chasing at all. Syntharra operates further downstream: on the invoices that slipped through, where payment wasn't auto-collected, or where a payment failed and follow-up is needed. The two tools address adjacent but distinct problems: Ignition removes the collection problem before it starts; Syntharra resolves it after it has already occurred.
When Ignition is the better choice
Ignition is the right tool for accounting firms that want to eliminate the collections problem before it starts. Syntharra is the right tool for businesses with existing overdue balances that need voice-call escalation to resolve.

Questions shops ask when picking between us and Ignition
Is Ignition a replacement for Syntharra?
No — they solve different problems. Ignition is designed to capture payment at the start of an engagement so invoices don't go unpaid in the first place. Syntharra handles the invoices that are already overdue. For accounting firms with both a preventive system (Ignition) and an occasional tail of unpaid invoices, both tools can run together.
My accounting firm uses Ignition — do I also need Syntharra?
Only if you have a meaningful tail of overdue invoices that Ignition's system hasn't resolved. Many Ignition users see near-zero overdue balances because payment is collected upfront. If your firm has exceptions — clients who dispute, payment methods that fail, or one-off work that wasn't in an engagement — Syntharra handles those.
Does Ignition have voice AI for collections?
No. Ignition's follow-up features focus on automated billing reminders and failed payment retries. Outbound AI voice calling is not part of the Ignition product as of 2026.
