The mandatory fields, and where businesses come up short

The Ministry of Finance published a mandatory fields specification alongside the guidelines, and that document is the practical heart of the whole thing. Everything else is transport; this is what your business has to produce.

What matters

What this means in practice

If you take four things away from this page, make them these.

1Party identification is the biggest gap

Correct legal names, tax registration numbers and addresses for both parties. This is where most businesses discover their customer data is incomplete.

2Line-level tax treatment, not invoice-level

Standard-rated, zero-rated, exempt and reverse-charge treatment is expressed per line. Systems that store one VAT rate per invoice have a problem.

3Dates, references and identifiers must be consistent

Invoice date, supply date, invoice number, and references to related documents all need to be present and correctly formatted.

4Totals must reconcile exactly

Line totals, tax amounts and invoice totals have to add up under validation. Rounding conventions that were tolerated in a PDF will not be tolerated here.

Practical steps

A short readiness list

Seven things that turn a vague worry into a manageable task list.

GoldenKey e-Invoice · in development

We are building our own e-invoicing app — and the ERP and CRM around it

We are not reselling somebody else's product. Zaini Developers is our own development team, and the e-invoicing engine sits inside the same platform that already runs CRM, accounting, POS and HR for UAE clients. That means when your business needs a field, a document layout or a report that a shrink-wrapped product does not have, we add it instead of putting it on a roadmap.

Branch & multi-companyRun several licences or branches from one login with separate numbering and reporting.
Roles & permissionsAccounts, sales and management each see only what they should.
CRM built inLeads, quotations, follow-ups and the invoice that eventually comes out of them, in one thread.
Accounting sideChart of accounts, double-entry ledger, receivables ageing and payment allocation.
Reports that answer questionsOutstanding by customer, VAT summary by period, revenue by branch or salesperson.
API for your existing stackIf you already run an ERP or a shop system, we integrate rather than replace.
Import your historyExisting customers and open invoices moved across from Excel, Tally, Zoho or QuickBooks.
Works on mobileIssue and check invoices from a phone — useful for site, showroom and delivery teams.
Hosted or on your own serverRun it on our hosting or inside your own environment if your policy requires it.

GoldenKey is a business setup and compliance consultancy. We are not a Ministry of Finance Accredited Service Provider, and we do not claim to be one. Our software is built to work alongside the ASP you appoint. Scope, timelines and pricing are agreed in writing before any work starts.

Questions we get asked

Frequently asked

Short, practical answers. If yours is not here, ask us directly — we answer even if you never become a client.

Where do I find the mandatory fields list?

The Ministry of Finance published a mandatory fields specification alongside the Electronic Invoicing Guidelines. Your provider will also give you their implementation of it.

What is the most common missing field?

The customer's tax registration details, closely followed by a legal name that does not match the licence.

Can I check my current invoices against it?

Yes, and you should. Send us a sample invoice and we will tell you which mandatory fields you are currently missing.
