CouponMate vs VAT Calculators

Browser extension that automagically searches for coupons

Coupon Identification & Collection Methodology:
In terms of backend end technology, we act as a meta crawler for codes using a variety of methodologies, from standard natural language processing to optical character recognition.

Every minute of the day, we’re actively crawling retailer’s sites, parsing their emails, SMS blasts, and social feeds while simultaneously monitoring other media outlets to source the latest and greatest codes.

Overall Site Support:
We detect code response, as in success or failure of a coupon specific to each site, on any type of site: static HTML, ajax-based or even mixed mode sites.

Overall, we monitor roughly 200,000 domains and variants for coupon codes currently. Roughly 80,000 of those have codes at the moment. Even if a site isn't supported for automatically applying a code, you're able to view coupons any time.

Automation / Coupon Validation:
We algorithmically validate coupons for sites enabled for full automation (aka Find Best Coupon functionality) daily. The moment we see a code applied that comes back “invalid”, “expired”, or a similar explicit failure — we remove it from our database. This allows for a sort of collective intelligence for all users to benefit from.

Add or remove value added tax

The new VAT calculator was established to calculate the Value Added Tax on invoices or receipts, while also providing guides on VAT rates, the Flat Rate Scheme and help-pages. Any business or individual can also access our handy calculator where the VAT rate can be changed. It can then be easily added to a net amount or subtracted from the gross amount.
