Non-PRO (1): TechLawDC
When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

Então, o que é a comissão de permanência?
A comissão de permanência é uma taxa cobrada pelo período de inadimplência do contrato. Ou seja, só pode ser aplicada no momento em que o devedor atrasa o pagamento do empréstimo ou financiamento. Então, de acordo com a regra do Banco Central e, também, pelas recentes decisões da Justiça, o credor pode, sim, cobrar dos devedores a comissão de permanência.

Outro exemplo:
A comissão de permanência, taxa cobrada pelas instituições financeiras quando há atraso no cumprimento dos pagamentos de responsabilidade do devedor, pode ser exigida legalmente durante a fase de inadimplência do contrato.

standing charge
I'm unsure it's synonymous with comissão de permanência.
Standing charge is also wide enough to cover a multitude of scenarios - from Portugal to Brazil, including the hotel overnight 'freshen-up' stay, as oddly described in the second web ref.
