Use a Spain-focused purchase order when you need to document a supplier order before the invoice arrives. The purchase order should identify the buyer, supplier, delivery details, items or services, agreed prices, currency, expected IVA treatment, payment terms, and approval contact. It is an internal buying document first, but it should prepare both sides for the invoice that follows.
Spain's full invoice rules sit mainly under Royal Decree 1619/2012, so the purchase order should collect the details the supplier will need later. A Spanish full invoice must identify supplier and customer names, addresses, and NIFs where required, then show description, taxable base, unit price, discounts, IVA rate, and IVA amount. Missing buyer details create invoice corrections after the goods or services are already delivered.
A purchase order is the buyer's request or authorization to buy. A Spanish invoice is the supplier's tax document for the completed supply or advance payment. The PO can include expected tax treatment, but the supplier's invoice carries the official sequential invoice number, issue date, taxable base, IVA rate, and separately stated IVA amount.
Spain uses IVA, with a 21% general rate, 10% reduced rate, and 4% super-reduced rate. The purchase order should not guess the rate when the item category is unclear. Ask the supplier to confirm the applicable IVA treatment before approval, especially for mixed orders with goods and services, exempt supplies, reverse charge wording, or special regime wording.
Start with the PO number, issue date, buyer name, buyer address, supplier legal name, supplier address, supplier NIF, buyer NIF where relevant, delivery address, contact person, payment terms, currency, and acceptance instructions. Add line items with a clear description, quantity, unit price before tax, discount, expected IVA rate, and any note that affects invoicing.
Use euros for IVA clarity even if the commercial amount uses another currency. Spanish invoices may express amounts in any currency, but any VAT charged must be expressed in euros. A practical PO line reads: "Design services, 12 hours, €75 per hour before IVA, expected IVA 21%, delivery by March 20, 2026." That line gives accounting enough detail to match the invoice later.
A free purchase order template is enough for a simple supplier order, a one-time project, or a buyer who only needs a clean PDF or spreadsheet record. It works best when prices, delivery terms, and approval are already settled. Keep the signed PO, supplier confirmation, delivery evidence, and final invoice together for audit and payment review.
A managed workflow becomes useful when supplier work connects to client billing, project costs, or recurring service delivery. Everhour Billing & Invoicing converts tracked billable time and expenses into invoices, calculates invoice amounts from rates while excluding non-billable tasks, and supports client settings, taxes, discounts, payment terms, and invoice customization. That workflow keeps the purchase record separate from the client invoice while preserving the billing trail.

A Spain purchase order is not a valid invoice. It records the buyer's approval to purchase goods or services, while the supplier's invoice documents the taxable supply. A Spanish full invoice needs a sequential invoice number, issue date, supplier and customer identification, taxable-base details, IVA rate, and separately stated IVA amount.
Collect the supplier's full business name, address, and NIF, then include the buyer's full business name, address, and NIF when the transaction requires it. Spanish full invoices must include the supplier's NIF, and the customer's NIF is required for domestic taxable operations and specified cross-border or reverse-charge cases.
Include the expected IVA treatment when the supplier has confirmed it, but do not treat the PO as the tax invoice. Spain's IVA rates are 21% general, 10% reduced, and 4% super-reduced. The final invoice must separately show the VAT rate and VAT amount charged, with any VAT charged expressed in euros.
A purchase order can use the commercial currency and language both parties accept. For the later Spanish invoice, amounts may be expressed in any currency, but any VAT charged must be expressed in euros. Invoices may be issued in any language, though the tax administration can require translation into Spanish or another official language in Spain for audit purposes.
For commercial transactions between businesses or with public administrations, the default payment period is 30 calendar days after receipt of goods or services if the contract does not set a date. Agreed payment terms cannot exceed 60 calendar days, so a Spanish business PO should avoid longer payment schedules.
Everhour Billing & Invoicing lets teams select uninvoiced billable time and expenses, preview the breakdown, and generate an invoice from rates, time, and billable expenses while excluding non-billable work. Invoice data can be grouped by project, task, person, date, or another available breakdown.
