Consultancies, agencies, IT firms and maintenance contractors bill time, milestones and retainers rather than stock. E-invoicing forces that billing into structured data, so engagement and timesheet records must be clean first.
Under Ministerial Decisions No. 243 and 244 of 2025, UAE service companies must issue B2B invoices as structured PINT AE e-invoices through an Accredited Service Provider. Consultancies, agencies, IT firms and maintenance contractors therefore need billing generated from the ERP: recurring retainer schedules, approved milestones, approved timesheets and AMC instalments, rather than invoices edited by hand in Word or PDF. Check the latest FTA guidance.
UAE e-invoicing for service companies looks simple until you list how you actually bill. A management consultancy invoices monthly retainers, milestone fees and rebilled travel. An IT company bills annual support contracts in advance and implementation hours in arrears. A facilities firm raises annual maintenance contract (AMC) instalments plus call-out jobs. Under Ministerial Decisions No. 243 and 244 of 2025, every one of these B2B invoices must be issued as a structured PINT AE e-invoice through an Accredited Service Provider (ASP).
The difficulty for service firms is that the invoice is often written by hand. A partner edits the narrative, a project manager adjusts hours, someone adds a disbursement line, and the final document is a Word or PDF file. Structured e-invoicing does not allow that kind of last-minute editing outside the system. The billing data has to come from the engagement, the timesheets and the expense claims in your ERP, and corrections have to be made with e-credit notes.
Your phase depends on revenue. Under current decisions, businesses with revenue of AED 50 million or more appoint an ASP by 30 October 2026 and go live from 1 January 2027; smaller firms appoint by 31 March 2027 and go live from 1 July 2027. Most service companies fall into the second group, which is covered further on our e-invoicing for SMEs page. Check the latest Ministry of Finance and FTA guidance, as dates have changed before. This page is general information, not tax advice.
The rules are the same for all sectors, but these are where service billing habits cause problems. Confirm each with your tax advisor.
Retainers and annual support fees are often invoiced before the service is delivered. Under VAT the tax point generally follows the earlier of invoice issue or payment, so the e-invoice date and the period it covers must be clear.
Travel, government fees and third-party costs passed on to clients may be treated as part of your supply or as disbursements, with different VAT results. Each line type needs its own tax code on the e-invoice.
Services to overseas clients may qualify for zero rating if conditions are met, and services bought from abroad usually fall under reverse charge. Check current guidance on how invoices to foreign clients are handled in the e-invoicing system.
Ministerial Decision No. 243 excludes certain financial services that are VAT exempt or zero-rated under Article 42 of the VAT Executive Regulation. Firms offering a mix of financial and advisory services should confirm which invoices are in scope.
Keep e-invoices with the supporting engagement letter, timesheets and approvals for at least 5 years under Cabinet Decision 74 of 2023, so fees can be supported in an FTA review.

This is the billing cycle we set up so the e-invoice is built from approved data and the ASP exchange runs without manual steps.
One shared database: every step updates stock, finance and reports in real time.
Each billing model needs a slightly different configuration. Platform-specific options are covered on our Zoho UAE e-invoicing and other platform pages.
| Billing model | Typical issue today | ERP setup for e-invoicing |
|---|---|---|
| Monthly retainer | Invoices copied from last month and edited by hand | Recurring invoice schedule linked to the contract |
| Milestone fees | Milestone sign-off held in email, invoice delayed | Milestones in the project with approval triggering the invoice |
| Time and material | Unapproved hours billed, then credited | Approved timesheets feeding billable lines with rates |
| Annual maintenance contract (AMC) | Instalments tracked in a spreadsheet | Contract with instalment schedule and renewal alerts |
| Call-out or ad hoc jobs | Job sheets on paper reach accounts late | Service request or field job closed in the app then invoiced |
| Rebilled expenses | Mixed with fees under one VAT code | Separate expense items with correct tax codes |
| Fee dispute or write-down | Original PDF edited and resent | E-credit note against the original e-invoice |
| Overseas client | Unclear VAT treatment | Customer tax profile and treatment confirmed by your advisor |

Smaller firms with one entity can move faster; groups with several practices and currencies need longer. Durations are typical ranges.

Still have a question? Our consultants are happy to help.
Ask an ExpertYes, but inside the ERP before the invoice is approved and sent. Once the e-invoice has gone through the ASP, changes are made with an e-credit note and a new invoice, not by editing the document.
Your obligation to issue e-invoices follows your own phase. Government entities themselves come into the system from 1 October 2027 under current decisions, so check with each government client how they want to receive invoices in the meantime.
Invoices can be issued in foreign currency, but VAT amounts must also be shown in AED under existing VAT rules. Make sure your ERP holds the exchange rate used and shows the AED VAT amount. Confirm the details with your advisor.
Smaller suppliers come in under the later phase, so you will receive a mix of e-invoices and conventional invoices for a while. Your AP process should handle both. Firms in facilities and maintenance can find more on field service management software.
If billing comes from timesheets, projects and contracts, an integrated system makes e-invoicing far simpler because the data is already structured. Our UAE e-invoicing software page compares the options.
Start with a short e-invoicing readiness assessment that reviews your billing models and invoice samples. It usually shows that timesheet approval and expense coding need attention before the ASP connection.
