Reading a quotation...
-
The quotation mentions rebuilding an Excel sheet to some web application. "This process must be as simple and correct as possible." Not "as correct as possible", just correct. If it's any less correct than "correct" it's not correct :laugh: I wonder, if they mention correctness explicitly at this point, does that mean all other points are assumed to be incorrect by default? :~

Correctness is a feature, after all ;)

I've actually had a customer who wanted VAT on invoices calculated per product, which was completely irrelevant, instead of over the complete invoice. The problem is, you're going to round VAT to two decimals, because no one ever pays €0.001. So by adding up all the VATs for each product we got rounding errors (and those rounding errors added up!). If you calculated the VAT over the entire invoice (like EVERYBODY in that business does) it wouldn't add up. But for some reason they really wanted to have the VAT per product. We went as far as to round to 16 decimal places, but we still ended up with rounding errors :laugh: Ultimately, we actually went for "as correct as possible with x decimal places." In this case "correct" was of course VAT over the entire invoice because that was the only legal kind of VAT :laugh:

Those little bits can add up :) Here if a product is marked as 4.99 you'll pay 4.95 at the till / cashier, due to us no longer having 2c coins. AFAIK the rounding is only done on the total, but if you wanted to save a few cents you could pay for each product individually.

At least in the UK, it's perfectly fine to do it either way: 17.5 Calculation of VAT on invoices - rounding of amounts[^] Calculating per line makes it easier to deal with invoices where different products attract different VAT rates. And if you calculate and round per line, you sometimes end up paying slightly less VAT. :)

So in practice you could get that new car invoice to be itemised by the atom and because HMRC allows you to round down there would be no VAT to pay :-D

What about "and correct if possible"? ;p Or "and correct if you pay extra for our special 'correctness module'" :cool:

I have a small feeling HMRC may see it slightly differently ... :~

Excel does a lot of magic; read theoldnewthing if you want details that you never need. Fun fact; Excel has better VB than the other MS products.

Over here, in a store (for example, supermarket), VAT is included in the product price. So 500 gr. (pre-packaged) grapes costs €2.19 incl. VAT. If you buy two packs, you pay €4.38. If you pay cash everything is rounded to 5 cents, so €4.38 would become €4.40, but €4.37 would be €4.35. I can't remember the last time I paid cash at a store :D This particular company sold meat (wholesale), so a customer would order five ribs, but they would pay per kg. The customer gets an estimated price, based on what my customer sent them, then that customer would weigh everything again, and that weight was invoiced. Naturally, you don't know the VAT until the actual invoice. And since the VAT isn't included in the individual prices, like in a supermarket, you really can't do anything other than calculate VAT over the entire invoice :D It's how I invoice too, and pretty much every business in the Netherlands.

Our local newspaper reported that "approximately five candidates" had failed this public exam. (The same local newspaper also once told about this guy who had one a huge prize in an English lottery: Until this, he had been selling fish and ships at a London street.)

I wonder if by correct they mean no hacks. In some cases hacks are acceptable if undesirable. The real world (deadlines and budget) often intervenes to undercut design, leading to kludges, and also maintenance can lead to kludgy code over time. Maybe by correct they mean with as little of this as possible. If I'm reading it charitably this is how I would interpret it.
