The short version

  • Each has a real cost: Spendbase charging a share of savings gives the vendor an interest in defining savings generously, and the customer cannot verify a counterfactual price it never saw.; TaxJar both published plans include only 200 orders per month, so higher volume costs more
  • They diverge on capability: Spendbase covers Subscription visibility, TaxJar covers Tax calculation.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Spendbase

  • Charging a share of savings gives the vendor an interest in defining savings generously, and the customer cannot verify a counterfactual price it never saw.
  • The savings share is reported at around 25 percent but is not published on the pricing page, so the actual commercial terms only appear in a contract.
  • Spendbase is both a banking provider and your software negotiator, so a company using both concentrates operating cash and vendor relationships in one small, young company.
  • Banking is delivered through partners rather than held directly, meaning deposit protection and service continuity depend on those partners rather than on Spendbase.
  • It is scoped for startups and small companies, so organisations needing approval workflows, purchase orders or ERP integration will find it thin against a real procurement platform.

TaxJar

  • Both published plans include only 200 orders per month, so higher volume costs more
  • The Starter plan at $39 per month allows only 3 data import integrations
  • AutoFile state filings are metered: Starter includes 2 credits a year and each extra filing costs $50, Professional includes 4 and each extra costs $55
  • Real time tax calculation API access requires the Professional plan at $99 per month
  • Phone support, a Customer Success Manager and a dedicated onboarding specialist require the Professional plan
  • The developer sandbox requires the Professional plan
  • The 10% saving requires annual billing
