When to pick Upflow

  • You have $5M+ ARR, a dedicated AR team, and need enterprise reporting, multi-entity consolidation, and CFO-level dashboards with DSO tracking.
  • You're already running NetSuite or have complex multi-currency billing with automated reconciliation — and you want to layer collections on top of a mature financial stack.

When to pick DueKeep

  • You're a solo operator, freelancer, or small shop with 5–50 clients, you send under 100 invoices a month, and you don't have (or want) an AR team.
  • You want to enter an invoice in 30 seconds, preview every reminder, and have an AI that knows when to switch from friendly to firm — without you being in the loop.
  • You're running on instinct and spreadsheets and just need something that works without a 3-hour onboarding call.
