Getting Started
Setting up WatCoreLite for your country
Not in India? Here's exactly what to change so tax, currency, and every invoice feel local to your business — GST or VAT, GSTIN or TRN, Rupees or Dirhams.
WatCoreLite started as a tool for Indian small businesses, and every default still reflects that — GST, GSTIN, HSN/SAC, Rupees. None of it is hardcoded, though. Every one of those is a label you can change in Settings, not a rule baked into the software, so a business anywhere else can make it feel like it was built for their country instead.
Tax name and tax ID
Under Settings → Tax: Tax label is what prints next to the percentage ("GST (18%)" by default — change it to "VAT", "Sales Tax", anything). Tax ID label is what your own registration number is called on the invoice ("GSTIN" by default — change it to "VAT Number", "TRN", "EIN"). The tax ID itself is free text either way — no format is checked or enforced, so it fits whatever your country's number actually looks like. The same relabeled field is available per customer too, for a B2B sale where they need their own tax ID on your invoice.
Product classification codes
"HSN/SAC" is India's GST classification system. The Product code label setting, right next to Tax ID label, renames it to "HS Code" or whatever your country calls it — and the column only ever shows up on invoices at all if you turn on "Show [code] codes on invoices" separately, so it's never forced on a business that doesn't need it.
Currency, all the way down
Under Settings → Invoicing, the Currency symbol picker already covers India, the US, the Eurozone, the UK, the UAE, Saudi Arabia, Qatar, Kuwait, Oman, Bahrain, Australia, and Canada — plus a Custom option for typing in anything else. That symbol is what shows next to every number. Separately, Currency name and Sub-unit name control the "Amount in words" line spelled out at the bottom of every invoice — "Rupees ... Paise" by default, but just as easily "Dirhams ... Fils", "Dollars ... Cents", or anything else.
One more thing changes with it: Number grouping. India groups large numbers as Thousand, Lakh, Crore — most of the world groups them as Thousand, Million, Billion instead. Switch this one setting and every spelled-out amount follows whichever convention actually reads naturally where you do business.

Your logo and your brand color too
Under Settings → Branding: upload your logo — a square image works best, since it's shown small and a tall or wide one gets cropped oddly — and pick an accent color that replaces the default lines and emphasis on every printed invoice and quotation with your own brand color. Two small settings, but they're usually what makes an invoice feel like it actually came from your business.
