Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Affirm

  • Longer instalment plans carry real interest, up to roughly 36 percent APR depending on the retailer, item and applicant, which is a genuine borrowing cost that the buy now pay later framing can obscure for shoppers who do not read the terms shown before accepting.
  • Even with no late fees, Affirm reports many loans to credit bureaus, so a missed or late payment on a longer plan can affect a credit score in a way the marketing around interest-free short plans does not prepare shoppers for.
  • Approval and APR both vary by individual loan, so the same shopper can be offered interest-free terms on one purchase and a high APR on another, making the cost unpredictable until checkout.
  • Merchants pay a transaction fee to offer Affirm at checkout, a cost typically built into retail pricing, so shoppers who pay by other means still indirectly subsidise the option even if they never use it.
  • The Affirm Card blurs the line between buy now pay later and a general-purpose credit card, and using it for everyday spending on interest-bearing terms can compound borrowing cost in a way a single point-of-sale purchase would not.

Invoice2go

  • Starter plan caps invoices at just 30 per year, forcing an upgrade for most active businesses.
  • Card processing fees are higher than some dedicated payment processors.
  • Accounting integrations are limited to QuickBooks and Xero, excluding other platforms.
  • Premium plan requires roughly $100k+/year revenue to be cost-effective, per its own positioning.
