Frequently Asked Questions

Can I customise the expiry?

Yes — default is 30 days, but you can set any date per estimate. Auto-expires on the date if not actioned.

Do estimates carry VAT?

Yes — exactly like invoices. When converted, the VAT carries through.

Can a client accept by clicking a link?

Email accept-link is on the immediate roadmap. Today you mark accepted manually.

What happens to an estimate after conversion?

It's marked converted and stays in the audit trail with a link to the resulting invoice.

Multi-currency?

Yes — same 12+ currencies as invoices.
