Guides

Compliance guides, written as reference

These are written to be useful rather than to sell — the product appears at the end of each one and nowhere else. Where a rule has a threshold that has moved more than once, the guide says what the rule is rather than quoting a number that will be wrong next year.

GST invoice rules

A tax invoice is the document your customer claims input credit on.

E-invoicing explained

E-invoicing does not mean generating an invoice electronically — almost everyone already did that.

E-way bill rules

The e-way bill is about movement, not about sale.

Filing GSTR-1

GSTR-1 is a statement of what you sold, and almost every problem with it starts on the invoice rather than in the return.

Filing GSTR-3B

GSTR-3B is a summary return where you pay.

GSTR-2B reconciliation

Your input tax credit is now largely whatever your suppliers reported, which means a supplier who has not filed has spent your money.

HSN codes

An HSN code is a classification, not a label, and the classification decides the rate.

Reverse charge

Reverse charge turns the normal arrangement around: the recipient pays the tax to the government instead of paying it to the supplier.

TDS & TCS on sales

These are income tax provisions that land in the middle of your sales ledger, and they are routinely confused because they look symmetrical.

UAE VAT explained

UAE VAT is a single rate applied to a small number of categories, which makes it simpler than most VAT systems and hides its one real trap: zero-rated and exempt are not the same thing, and the difference decides whether you can recover your input tax.

TRN registration

A Tax Registration Number is how the FTA identifies a taxable person, and it is the single field on an invoice most likely to cost somebody money — because a customer cannot claim input credit against a tax invoice carrying a wrong or absent TRN.

UAE corporate tax

Corporate tax changed what bookkeeping is for in the UAE.

Double-entry basics

Double entry is not an accounting convention invented to make life difficult.

Stock valuation

The value of your closing stock is the value of your profit, because everything you did not sell is not a cost.

Let the software remember the rules

tBiz checks what would be rejected before you file, rather than after.
