Every organisation suffers from inept software design. Huge, huge write offs and adjustments occur in any bank or accounting system.
Horizon was bespoke to the UK Post Office - no other company has a need for it. (OK, it's built on generic standard software packages and tools, but really their problem comes from the overall Horizon system design and implementation).
As you point out, these guys lost money on rounding and adjustments, and that triggered alarm bells. What you can be equally sure of is that others MADE money on rounding and adjustments, and - perhaps strangely - they didn't complain about it. It's unlikely that the Post office HQ "made the money" that the sub-postmasters lost.
The 700 cases were about relatively tiny sums of money - a few million, in the context of a whole business that turned over around £10,000,000,000 during that decade. "A billion here, a billion there, soon you're talking significant sums of money" compared to a handful of million.
The Accountants and Lawyers at the Post Office should have sorted this out more than a decade ago. That much is clear. But watch out when you write that cheque for £150 million to pay off everyone involved: the main beneficiaries will be a lot of lawyers and accountants, on both sides, who'll be buying holiday homes in Southern Spain on the profits that they're now making from the payoff.
These were not rounding errors. The documentary showed the lawyer found error documents where the Horizon had lost communication (and therefore inputs). These were sometimes spotted and sometimes manually adjusted, but some Horizon tills seem to have been worse than others and calculations missed. The Sikh lady's prosecution failed because her Horizon till went off for repair and was not available as evidence. - judge at the time said well it must be faulty then therefore PO cannot prove it was working correctly (but that was a one off). Plus, the Post Office swore blind that no one except post masters had access to their accounts when in fact Fujitsu IT nerds did (and were tampering with the numbers). This is pretty different to normal rounding errors or skimming.
Pure speculation: It could be conceivable that some post masters were used to skimming tens of pounds here and there and when the PO came knocking with a £10k bill they paid up in a panic...
