Each has a real cost: Rutter a unified schema exposes only the fields common across platforms, so the platform-specific detail underwriting models want usually requires passthrough calls and per-platform code, which is the work the unified API was bought to avoid.; Zimpler pricing is not published and is set by industry and risk profile, so smaller merchants cannot benchmark a quote and often discover they are paying well above a general-purpose provider.
They diverge on capability: Rutter covers Accounting and ERP, Zimpler covers Bank payments.

Where each one falls short

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

Rutter

A unified schema exposes only the fields common across platforms, so the platform-specific detail underwriting models want usually requires passthrough calls and per-platform code, which is the work the unified API was bought to avoid.
Write operations into accounting systems are where these products break, because each system validates differently, and a rejected journal entry surfaces as a support ticket against you rather than against the ERP.
No pricing is published beyond a sandbox trial, so cost cannot be compared against alternatives without a sales process, and pricing tends to scale with connected accounts.
QuickBooks Desktop and other on-premises systems require a local connector or hosted agent, which introduces installation steps your customers must complete and support burden you inherit.
Sync freshness varies by platform and by customer authorisation state, so a product promising near real-time figures will find some connections update far less often than the marketing implies.

Zimpler

Pricing is not published and is set by industry and risk profile, so smaller merchants cannot benchmark a quote and often discover they are paying well above a general-purpose provider.
As a payment facilitator carrying merchant risk, it declines or offboards merchants on risk grounds, which makes it a dependency you cannot assume will persist.
Its strength is concentrated in the Nordics, and coverage in southern and eastern Europe is thinner than pan-European account-to-account specialists.
Revenue concentration in iGaming ties the provider to a sector under constant regulatory change, so licence changes in one market affect the supplier as well as the merchant.
Bank transfers have no chargeback protection, so disputes are handled commercially and consumers used to card protections may resist the payment method.

Answered from the vendors’ own pages

Rutter: Does Rutter support QuickBooks Desktop?

Yes, which distinguishes it from unified APIs that only cover cloud accounting, and matters because many small businesses still run it.

Zimpler: Which markets does Zimpler cover?

Sweden and the Nordics primarily, plus the wider EU and Brazil. It is strongest where national electronic identity schemes exist.

Rutter: Can Rutter write data back?

Yes. Invoices, bills and journal entries can be pushed into supported accounting systems, not only read.

Zimpler: Does it handle identity verification?

Yes. In the Nordics it captures BankID identity alongside the payment, which removes a separate verification step.

Rutter: Is there a free tier?

There is a thirty day sandbox trial with test data. Production access requires a paid plan with quoted pricing.

Zimpler: Is pricing published?

No. It is quoted per merchant based on sector, risk and volume, and merchants must pass underwriting first.

Rutter: What if the unified model lacks a field I need?

Rutter supports passthrough requests to the underlying platform API, though using them reintroduces platform-specific code.
