Turnover grew to £29.7m in the year to 31 May, while profits increased by 24.8% to £1.46m, giving it a profit margin of 4.9%.
The business, which distributes toiletries and some food lines to wholesalers, independent c-stores and pharmacists, was boosted by a new contract to exclusively supply all 51 branches of variety retailer The Range with toiletries and cleaning products.
Last month it also began distribution for P&G.
"We run a lean business through an intelligent technology-driven stock management system and by keeping our fixed overheads low," said director Stephen Shortt, who runs the business with twin brother Richard.
"Our promotions are market-beating and we keep our prices very competitive. Above all we pride ourselves on a flexible, personal service. All customers have a dedicated account manager."
Shortt said the company had set its sights on a £36m turnover for its current financial year. It intended to achieve this by continuing to stock to its current business model, and by winning new customer distribution contracts, together with expanding its sales force, investing in IT, and bringing on new key manufacturer suppliers.
Intamarque launched a new website last month allowing customers to place orders online.
