How we worked it out
- PrimeSign: Essentials is A$60 × 12 = A$720 a year with 150 envelopes a month included. Professional is A$110 × 12 = A$1,320 with 400 a month. At 300 a month, Essentials plus 150 extras at 40c would be A$1,440, so Professional is used. Every user and every signer is included.
- Annature: 100 a month is 1,200 envelopes a year × A$1.75 = A$2,100. 300 a month is 3,600 × A$1.75 = A$6,300.
- Annature asks firms sending more than 100 envelopes a year to ask for a quote. Volume prices are not published.
- Annature fees exclude GST, per its subscriber agreement. It bills monthly with no lock-in.
- PrimeSign SMS codes (Planned): 10c per text on Starter and Essentials, included on Professional. One text per envelope would add A$120 a year at 100 a month on Essentials, and nothing on Professional.
- Annature SMS: 12c per text. One text per envelope adds A$144 a year at 100 a month, or A$432 at 300. Branded SMS links are A$15 a month extra.
