Ireland VAT Invoices: A Checklist for Service Businesses and Suppliers

Revenue's VAT invoice particulars and timing

Revenue lists issue date and unique sequential number, seller and customer details, supplier VAT number, nature and quantity of goods or extent of services, supply date, VAT-exclusive unit prices, discounts, rate breakdown and VAT total. Conditional particulars can include the customer's VAT number and reverse-charge wording. Consult the official list for your case rather than assuming every EU transaction has identical requirements.

Revenue states that VAT invoices must generally issue within 15 days after the end of the month of supply. Check its separate treatment of advance payments and cross-border supplies before applying that timing to a particular transaction.

EUR example: bill an accepted service milestone

Fictional example: a Galway designer agrees EUR 800 for research and EUR 1,200 for a finished brand pack. The net commercial amount is EUR 2,000 before applicable VAT. The quote defines deliverables and revisions; the client approves research before final design begins. If billing is staged, identify the stage and period rather than using an unexplained 'design service' line.

• Keep accepted quotation and service terms together.
• Ask for the client's billing name and PO where required by its purchasing process.
• Retain milestone acceptance and the supply period.
• Apply confirmed tax treatment and mandatory particulars.
• Reconcile money received against the correct invoice; issue a receipt for actual funds, not promised payment.

Goods suppliers should retain receiving records showing quantities actually supplied. For onboarding, a company profile introduces experience and capacity but does not replace registration evidence. A service agreement should define change approvals, responsibilities and acceptance; obtain professional review where appropriate.

What the invoice maker cannot decide

EUR selection and a VAT identifier help prepare commercial inputs. DocMak does not decide Irish registration, reverse charge, intra-community treatment or Revenue reporting. Its single-rate calculation and GCC presets may not cover your transaction. Check discounts and rounding against accounting records and use an appropriate system when additional tax breakdowns or statutory particulars are needed.

Prepare the document, then check before sharing

1. Replace sample seller, customer, bank and tax details with verified information.
2. Choose the agreed currency before entering amounts and check every displayed currency label.
3. Confirm registration and supply treatment before setting tax; do not keep the GCC sample rate by default.
4. Review invoice number, supply and issue dates, buyer references, quantities, discounts, rounding and payment due date.
5. Preview and review the downloaded document. Use the appropriate invoicing system for mandatory fields or tax treatments the editor cannot express.

DocMak prepares commercial documents, not officially approved local tax invoices. Its invoice editor currently has GCC country presets, a single editable tax rate and VAT-labelled totals. Currency and GST/VAT identifiers alone do not establish compliance. Use an appropriate system wherever additional particulars, structured invoicing or reporting are required. Currency selection does not convert amounts. Creation, downloads and free-account reuse remain subject to existing plan limits.
