I was disheartened nearly instantly with HMRC's attitude:
"If there’s any disagreement between you and us that can’t be resolved, we reserve the right to temporarily or permanently remove your access to our APIs"
That's their idea of collaboration!
I think I will leave it to the professional software firms. However, what will their prices be- £10 per month per client?
Dd our extra costs between £30 - £50 per month per client?
Will our clients be happy to pay the increased fees of £480-£720 per year if they are only on fees of £2,500 per annum for something that is only compliance? There is no carrot here and I hope HMRC publish a big stick fine so that I can keep clients compliant.
I will get back to burying my head in the sand until the end of February 2019.
