Ignition at ignitionapp.com is proposal and billing software for accounting firms, bookkeepers, and other professional services. It is not a car product. You send a branded proposal, with up to three package options, plus an engagement letter. The client signs and enters payment details. Ignition then creates invoices in QuickBooks Online or Xero on the schedule in the proposal, and Ignition Payments can mark those invoices paid.

TaxDome and Canopy also send proposals and take payment, inside a system that runs the firm's jobs and portal. Ignition is the agreement and the recurring bill, not that operating system. Double (formerly Keeper) closes the client file. Ignition does not categorize transactions or replace the ledger. The books stay in QuickBooks Online or Xero, which is where the invoice and the payment land.

Firms stick with it when they are tired of rebuilding a Word letter and then chasing the first payment. The card or bank details are on file before the work starts, so a monthly fee can run from the signed proposal. A scope change can be billed from the same client instead of a new contract from scratch.

Build a branded proposal from templates and a service library, with up to three options and add-ons. Engagement terms go out with it. The client signs online. Solo and Core include one signature per proposal. The US pricing table shows up to 2 on Pro and up to 10 on Pro+.

Send the proposal and the engagement letter together

The client enters a card or bank account on the proposal. Ignition can bill one-off, recurring, hourly, weekly, quarterly, or annual schedules. During the 14-day trial you can collect up to $10,000 with zero payment fees. After that, US standard cards are 2.5% + $0.30, premium cards are 3.6% + $0.30, and ACH is 1% + $0.30 with a $5 cap, plus 0.3% on the amount above $3,000.

Collect payment details before work starts

When the client accepts, Ignition creates the invoice in QuickBooks Online from the proposal lines and can match a new client or update the name. It can also import recurring QuickBooks invoices and turn them into draft proposals. The Xero integration page describes the same pattern: invoices from the proposal, and payments marked paid.

Create the invoice in QuickBooks Online or Xero

US annual prices on the pricing page: Solo is $39 for 20 active clients and 1 user (under $150k revenue), then +$7 per extra client. Core is $99 for 50 clients and 3 users, then +$5. Pro is $229 for 350 clients and 15 users, then +$3. Pro+ is $399 for 600 clients and 20 users, then +$2.

Stay inside the client and user caps

The pricing table lists single renewals on Core and bulk renewals on Pro and Pro+. Online forms are included on Pro and Pro+ and an add-on below that. The deals pipeline is included on Pro+ and an add-on on lower plans. The product page also lists billing for out-of-scope work. Add-on dollar amounts were mixed across currencies, so they are not repeated here.

Renew, reprice, and bill work outside scope

Proposals, engagement letters, and recurring invoices for firms. US Solo is $39/mo billed annually. Not a vehicle product.
