Billtrust vs Esker (2026): which should you pick?

Pick Billtrust if

• Fits if you're a B2B supplier chasing customer invoices and payments
• Works for finance teams that want credit, collections and cash application in one place

Look elsewhere if

• Skip it if you need to pay vendors or track employee expenses, as it only covers receivables
• Skip it if you want a price before talking to someone: none is published
• Watch out: the pricing page returns not found, and buyers are sent to talk to an expert
• Watch out: the pages we read didn't name ERP integrations

Pick Esker if

• Fits if you want invoices, purchasing and collections handled in one suite
• Works for finance teams that already run an ERP and want to add to it

Look elsewhere if

• Skip it if you need employee expense reports; they show up only as a mobile approval item
• Not for you if you have no ERP, because it sits beside one rather than replacing it
• Pricey if you want to compare costs first, as no price is published
• Watch out: the site mentions mobile approvals but names no iOS or Android app

Billtrust

• No prices are published on the site; the pricing page returns not found and the site directs buyers to talk to an expert.
• It covers accounts receivable, so it does not handle employee expenses, cards or paying vendors.
• The site lists English, Dutch and German versions, and the pages we read did not name ERP integrations.

Esker

• No prices are published; the site directs visitors to request a demo or contact sales.
• It is built around invoices, purchasing and collections; employee expense reporting appears only as a mobile approval item.
• It sits beside an ERP rather than replacing one, so a company needs its own accounting system.
• The site mentions mobile functions for approvals, but does not name iOS or Android apps.
