Guides

Invoice, quotation or receipt — which document for which moment, and the shortcuts that are perfectly fine for small jobs in Sri Lanka.
Send an invoice on WhatsApp the professional way: the 4-step flow, what your client sees, and habits that make you look established.
Which details to include, due dates that get you paid, and killing the “account number please?” round-trip.
One invoice per order, in the same chat: the 60-second workflow for Sri Lanka's Instagram, WhatsApp and DM sellers — free tools included.
Why a 12% flat quote costs the same as 20.3% reducing, the worked example and the 3 questions to ask before you sign.
Scope, revisions, deposits, payment terms, with a realistic sample invoice you can open pre-filled in the tool.
The 4 cost buckets every product needs, the margin vs markup trap, and a worked coconut-cake example — with a free multi-product costing calculator.
Every guide carries English, Sinhala and Tamil tabs — written natively, never machine-translated.
