Nothing on this site can be bought by clicking. There is no catalogue, no checkout, no subscription and no self-serve plan — the forms here start a conversation and nothing more. A payment only ever follows a proposal or statement of work that both parties have signed.
Every invoice references that signed document and is itemised against it, so a line on an invoice can be traced to a line in something you agreed. Rates appear in the proposal, broken down by role and seniority, alongside the assumptions the estimate depends on. This is why the site publishes no rate card: a number detached from the shape of the work is not comparable between suppliers, and the engagement and pricing page sets out that reasoning in full.
We accept bank transfer, and card or other online payment where we have made that route available to you. In every case the amount, the currency and the applicable tax are the ones stated on the invoice.
We will never ask you to pay through a channel that does not appear on an invoice we have issued — not by message, not to an account given verbally, and not to an address that differs from the one on your contract. If you receive a payment request purporting to be from MENTARA and anything about it is inconsistent with this, treat it as fraudulent and tell us before acting on it.
