ContaPlus is an accounting software solution for small businesses offered by Sage in Spain. It includes tax features and handling data for other legal requirements.
History
First offered in the early 1980s by Grupo SP, it gained incredible popularity in 1990 by using news stands as point of sale and was offered at very low prices at a time where professional accounting was very expensive. ContaPlus also took advantage of the Spanish accounting reform of 1990. Nowadays, ContaPlus is the "accounting standard" in Spain with more than one million customers. Grupo SP was purchased by Sage in 2003.
