What to settle before you issue your first invoice

Five decisions that are cheap to make before the first invoice and expensive to change afterwards — numbering, VAT registration, payment terms, the legal entity on the document, and what happens when a client does not pay.
An invoice looks like a formality. It is actually the first place your company makes several decisions that are difficult to unwind, and most are made by accident — by whatever the accounting software defaulted to on the day someone was in a hurry.
Here are the ones worth ten minutes before you send the first one.
1. Numbering, and why gaps matter
Invoice numbers must be sequential and gap-free. That is not a stylistic preference: a missing number in a sequence is the first thing a reviewer asks about, and the honest answer is usually 'we deleted a draft', which is not a satisfying one.
Decide three things now. Whether the sequence resets each financial year. Whether credit notes continue the invoice series or run their own. And the format itself. Changing any of them after the first real invoice means a restatement rather than a settings change.
If you run more than one line of business, give each its own series. Being able to tell consulting revenue from subscription revenue without parsing descriptions is worth the small amount of setup it costs.
2. Do not show a tax number you do not have
In the UAE, VAT registration is mandatory once taxable turnover passes AED 375,000 in a rolling twelve months, and voluntary from AED 187,500. Below that you are not registered, which means two things that people get backwards.
You must not charge VAT. And you must not show a TRN on the document — including an empty TRN field, which implies one exists. Charging tax you are not registered to collect is a penalty, and it is one of the most common early-stage mistakes because the invoice template came with the field already on it.
The practical move is to make it impossible rather than remembering: configure the system so the standard-rate tax template does not exist until a real TRN is recorded.
3. Payment terms are a decision, not a default
Thirty days is conventional for consulting and ruinous for a small company delivering a four-week engagement. Different lines of business genuinely need different terms, and there is no reason they should share one.
Write them on the quotation, not just the invoice. Terms a client first sees after the work is done are terms they will argue about.
4. The name on the document
Use the registered legal name exactly as it appears on the trade licence, including the legal form. 'YK Global' is the trading name; 'YK Global FZC LLC' is the entity that can sue and be sued, and it is what belongs in the signature block of anything with legal weight.
Put the licence number and registered address on it too. A buyer who can verify you are a real registered entity is a buyer who stops wondering.
5. Decide now what happens when someone does not pay
Not the dramatic version — the ordinary one. How many days before a reminder. Who sends it. What it says. At what point a person makes the decision instead of an automated schedule.
The specific thing worth building in is a stop: an invoice a client has formally queried must drop out of the automated chasing immediately. Chasing a disputed invoice is how a collections process destroys a relationship the sales process spent months building.
None of this is about accounting software
All five are commercial decisions that happen to be expressed in a system. Make them deliberately and the system is a record of your choices. Leave them to defaults and the software has quietly made them for you — and you find out which ones it got wrong at the worst possible moment, usually during an audit or a dispute.
