The All The Little Shops (ATLS) web tool provides its independent retailer members with a dedicated web page on which they can showcase their deals, services and up to 20 top products which can also be bought and paid for online before collection from the store.
It also enables retailers to offer customers bespoke downloadable incentive vouchers, and to run monthly e-newsletters without the need for a costly e-commerce website of their own.
ATLS managing director Peter Riches said the tool, which costs retailers £20 a month to use, was helping retailers to trade on a more level playing field with the multiples.
ATLS aims to work closely with councils and town centre managers to produce more community and town centre websites which showcase local retailers.
Last month the town of Colwyn Bay in North Wales became the fifth location to sign up to the scheme.
