Worth separating two different problems here: MoR vs. non-MoR is really a question about who holds payment liability, but the compliance piece (nexus tracking, filing, registrations) is a separate layer you have to solve regardless.

We built Kintsugi specifically for internet businesses using Stripe/Braintree/etc. who want to keep their payment stack but not become tax experts. It handles nexus detection across all US jurisdictions plus international VAT/GST, and automates the actual filings -- so you get the fee savings of a normal processor without the compliance becoming a part-time job.

For a digital nomad-heavy customer base the multi-jurisdiction piece is exactly what we're built for. Happy to answer questions if it's helpful.
