My guess is they have already received the cash mentioned. Remember, the US balance (financial) date is 31 December. So they do not want to pay for this year’s contracts before this year. Some do not want to sign contracts before the current year.
The 3DP contracts are complex and often need integration into the customer’s existing systems which also takes time before their is ‘sign-off’ by the customer that the Pointerra product has been delivered and can now be paid.
This is how major and complex contracts work.
This also works for Pointerra, because once the Pointerra systems are integrated into the customer’s systems, the contract become’s very ‘sticky’.
