Trade-offs

  • Pricing makes it unrealistic for small businesses per Capterra reviewers - entry $39 climbs to $229 quickly.
  • Only Stripe payment integration - no DocuSign integration, no payment alternatives.
  • Payment deposits take 5 to 7 business days to reach bank - factor into cash flow planning when switching from manual billing.
  • Only one stage of process - need separate practice management for projects/tasks.
  • No pre-authorized debit in Canada per Capterra reviewer - affects Canadian market.
  • Cost increases significantly for each feature - non-competitive after add-ons.
  • Does not support payments in South Africa (in roadmap).
  • Refund processing times reported as slow.
  • Default un-editable wording on client-facing documents confuses some clients (refers to Proposal even when used as Letter of Engagement after another platform).
  • For all-in-one practice management (projects + tasks + clients + billing), Karbon or Canopy broader.
  • For solo practitioners with under $150K annual revenue on tight budget, Solo plan may still feel expensive at $39/mo.
  • For instant payment processing requirements, 5-7 day deposit delay disqualifying.
  • For non-accounting professional services, generalist proposal tools (Proposify, PandaDoc) more flexible.
  • For project management features alongside proposals, Asana or Monday integration required.
  • For agencies wanting deep CRM integration, dedicated CRM (Pipedrive) better separate.
  • For freelancers or solo consultants, simpler tools like Bonsai or HoneyBook cheaper.
  • Pro plan jump from Core $39-49/mo to Pro $229/mo significant for mid-tier firms.
  • Some accountants use external pricing software to build bespoke prices before importing into Ignition.
