SumUp USA
Pros
- + Setup took under fifteen minutes from unbox to first contactless payment in my testing, with no underwriting wait on the standard account
- + Flat, published pricing: 2.6% + 10¢ in person, 3.5% + 15¢ online/keyed, $0 monthly cost on the standard product — settlement matched the schedule in my test transactions
- + Hardware is owned outright (readers from $99), not rented, and some devices include free unlimited cellular connectivity
- + Broader ecosystem than the reader suggests: POS subscriptions from $99/mo, a SumUp Mastercard debit card for spending takings, and a developer transactions API
Cons
- - Flat-rate pricing is a convenience tax at scale — interchange-plus providers undercut it once volume is meaningful
- - Keyed transactions cost 3.5% + 15¢, a full point above in-person, so phone orders quietly raise your effective rate
- - Real retail features (advanced inventory, staff controls, loyalty, multi-location) sit in POS subscriptions at $99+/month
- - Payout scheduling and fund-hold discretion are standard aggregator risks — SumUp's terms allow payout timing control, so don't park cash flow you can't afford frozen
AssemblyAI
Pros
- + Transparent, published rate card: $0.15/hr for Universal-2 and $0.21/hr for Universal-3.5 Pro at time of writing (assemblyai.com/pricing.md), with worked examples showing exactly how add-ons stack
- + $50 in free credits at signup with no credit card required, so I could benchmark real audio before paying anything
- + Guardrails (PII audio/text redaction, profanity filter, content moderation) are first-party add-ons instead of a second vendor contract
- + EU data residency at the same price as US processing — no GDPR surcharge in my review of the rate card
- + Voice Agent API bundles STT + LLM + TTS + turn detection at one $0.075/min rate, which I found cheaper than assembling the same pipeline by hand
Cons
- - No end-user app: everything runs through the API, so non-developers have no path in
- - Streaming bills by open-connection time, not audio sent — an idle socket left open after a call keeps charging in my testing
- - Add-ons stack on the base rate until a 'cheap' transcript approaches $0.40–$0.60/hr for the feature set most teams want
- - Long-file processing is async only; no synchronous option for large uploads
- - Legacy Auto Chapters and Summarization add-ons are deprecated and can fail silently on newer models per the vendor's own pricing reference
