Business Settings is where your company’s identity lives in JingjaiOps. Everything here flows onto every PDF, email, and portal page.

​

​
Logo guidelines

  • Light logo — your logo on a light background (used on the standard PDF header and in the portal’s light mode)
  • Dark logo — your logo on a dark background (used in the portal’s dark mode)
Upload both for the best result. If you only upload one, JingjaiOps uses it in both modes (with a slight risk that it doesn’t look great in the off-mode).

​
Tax information

FieldNotes
Tax IDYour 13-digit Thai Tax ID. Required to issue Tax Invoices
VAT RegistrationTick if VAT-registered. Default 7%
Branch”Head Office” or a branch number
VAT Number (if different from Tax ID)Some businesses register VAT separately
If you tick VAT Registration, every quote, invoice, and Tax Invoice automatically calculates 7% VAT.

​
Currency and VAT rate

FieldNotes
CurrencyDefault THB. You can switch to USD, EUR, etc. for international quotes
VAT RateDefault 7%. The current Thai VAT rate. Editable for special cases
RoundRound VAT to nearest 1 / 0.01. Default 0.01
JingjaiOps supports multi-currency on a per-quote basis, but the business’s default currency drives reports. Keep the default at THB unless almost all your business is foreign.

​
Document prefixes

The prefixes for every document type are configurable:
DocumentDefault PrefixEditable
QuoteQT-Yes
JobJOB-Yes
InvoiceINV-Yes
Tax InvoiceTI-Yes
Regular ReceiptRC-Yes
Pre-payment ReceiptPREREC-Yes
DepositDEP-Yes
Deposit ReceiptDEPR-Yes
Deposit Return ReceiptDEPRR-Yes
Credit NoteCN-Yes
If you change a prefix, the change applies to future documents only. Past documents keep the prefix they were issued under.
Changing prefixes mid-year can confuse accounting reconciliation. We recommend deciding on prefixes before issuing your first document and not changing them after.
