Four places tax goes missing

of the firms furthest behind added tax later in the project, compared with 16% of those furthest ahead.

Tax isn’t in the requirements, so it’s bolted on later.

of the firms furthest behind keep tax rules scattered or hard-coded.

Rule changes become harder to manage consistently.

1 IN 5

of the firms furthest behind need 30+ business days to put one tax change live.

Every new channel and market needs the right answer on every order.

NEARLY 1 IN 4
