What's the best billing software for collecting tax prep fees upfront from seasonal clients?

For tax prep firms that want to collect fees upfront from seasonal clients, the best option for most practices is usually Canopy or TaxDome, with Ignition as the strongest pure payment/proposal tool if you already have a separate practice management system.

Best overall for tax preparers: TaxDome

Why it’s a strong fit:

• Built for accounting/tax workflows
• Easy to send engagement letters + invoice/payment request upfront
• Supports automation for seasonal client onboarding
• Good client portal for collecting docs and payments together
• Helps reduce no-shows and “pay later” problems

Best if you want:

• An all-in-one system
• Client portal + document collection + billing
• Strong automation for high-volume seasonal work

Best if you want a more polished all-in-one client experience: Canopy

Why it stands out:

• Good for billing, payments, and client management
• Professional client portal
• Works well for firms that want to standardize intake and collect payment before work starts
• Solid for growing firms

Best if you want:

• Strong UI/UX
• A modern client experience
• A broader practice management platform with billing built in

Best pure billing/proposal tool: Ignition

Why it’s useful:

• Excellent for upfront payment collection
• Great for proposal + engagement + payment workflows
• Can require payment before work begins
• Strong recurring billing and payment automation

Best if you already have:

• Practice management elsewhere
• A need mainly for proposal-to-pay collection

Other options worth considering

• QuickBooks Online + Payments: fine for simple invoicing, but not ideal for a seasonal tax workflow
• Drake Tax / UltraTax / Lacerte add-ons: may fit if you’re already in a specific tax ecosystem, but usually less flexible than dedicated tools
• Bill.com: better for AP/AR than for tax prep intake workflows

My recommendation

• If you want the best fit for seasonal tax clients: TaxDome
• If you want a clean modern all-in-one firm platform: Canopy
• If you only need upfront billing and engagement collection: Ignition

What to look for specifically

Make sure the software can:

• Require payment before work starts
• Send automatic reminders
• Support engagement letters
• Handle deposit/full prepayment
• Integrate with your tax software and payment processor
• Make it easy for seasonal clients to pay on mobile
