Your first invoice

Who is it for?

01 · Day one

Set up your business

  • Sign up with your business name and pick your trade - 16 are built in, from fruit & vegetables to furniture.
  • Pick your country, then add your tax number (TRN, VAT number or GSTIN), address, bank details and signature once; they print on every invoice.
  • Choose whether your prices include VAT. You can still flip it on any single invoice.

02 · Catalog

Add what you sell

  • Group products into categories and subcategories - Vegetables › Leafy greens, Bedroom › Mattresses.
  • Choose how each item is sold: pieces, kg, grams, litres, metres, boxes, cartons, hours or nights.
  • Set a reorder level and Kayyro flags anything running low on the dashboard.

03 · Customers

Customers & credit

  • Save each customer's country, tax number, phone and email so invoices and reminders fill themselves in - customers abroad are reverse charged or zero-rated for you.
  • Record part payments; every customer gets a running ledger and balance.
  • The Outstanding page sorts debts by age so you chase the oldest money first.

04 · Get paid

Email, WhatsApp & reminders

  • Email any invoice with the PDF attached, or select many and send them all at once.
  • Payment reminders go to every customer who owes you - one click, with their balance filled in.
  • Prefer chat? Share the PDF link on WhatsApp straight from the invoice.

05 · Every morning

Your dashboard

  • Today's sales against last week, a monthly goal ring and your billing streak keep momentum visible.
  • See money waiting to be collected, best sellers, top customers and stock that needs attention.
  • A VAT set-aside estimate for the quarter so filing day is never a surprise.

06 · Compliance

VAT & GST returns

  • Your return in your country's layout: UAE VAT 201 by emirate, Saudi VAT return, UK 9-box, India GSTR-3B with IGST / CGST / SGST, or output and input VAT for the rest.
  • Export the workbook to Excel for your accountant, along with sales and purchase registers.
  • Credit notes and zero-rated or exempt supplies are handled in their own boxes.

07 · Stock

Inventory that moves itself

  • Every invoice deducts stock and every purchase adds it - including decimals for weights and lengths.
  • Stock in, stock out and counted adjustments are kept in a full audit trail.
  • Multiple warehouses on the Business plan.
