For craftsmen and small sole traders · invoicing for craftsmen

Invoicing for craftsmen — small trades, B2C, seasonal work

Small craftsmen, micro sole traders and self-employed make up the largest group of Slovak entrepreneurs by count, yet with the simplest invoicing agenda. Typically a sale to a private individual (B2C), an occasional B2B job for a company, seasonal turnover swings (especially in construction, gardening, auto service) and most often non-VAT-payer — turnover stays below the €50,000 12-month threshold. Despite the simplicity, there are concrete invoicing mistakes the Slovak tax office catches at audit and penalises. This guide shows how to invoice a small craftsman business correctly and when to consider voluntary VAT registration.

Industry pain points

What you wrestle with daily.

Four concrete problems almost everyone in this industry hits. You'll find a fix for each below — or the full set in the 1FAKTURA cloud product.

01

Ad-hoc invoices for B2C individuals

A carpenter / plumber / hairdresser issues 5–15 invoices a month, mostly to individuals. Manual calculations, manual numbering, risk of duplicate numbers — which the tax office happily flags during an audit.

02

Seasonal turnover swings

A gardener earns 80 % of the annual turnover from March to September. From an accounting standpoint that is fine, but cash flow is uneven and the seasonal records pile up.

03

Travel and material expenses

A plumber drives to repair a bathroom — invoices labour + material + travel. Common mistake: lumping everything into one line without a breakdown, which complicates both bookkeeping and liability insurance.

04

VAT threshold turnover

A craftsman approaches €50,000 turnover over 12 months. If they cross it, they must register as a VAT payer within 20 days. Without turnover tracking it is easy to miss → penalties and VAT back-payment.

VAT specifics

Which VAT regime applies.

Reference: § 4 of Slovak VAT Act (registration) + § 27 (rates)

Full statute: slov-lex.sk.

Small craftsmen are typically non-VAT-payers — with turnover below €50,000 over the last 12 calendar months, they are not required to register. The invoice is at 0 % VAT (effectively no VAT columns), with the note „I am not a VAT payer“ (or „Invoice without VAT under § 4 of the Slovak VAT Act“). With voluntary registration, they invoice at 23 % VAT as normal payers — advantageous with a high B2B share (clients can deduct VAT, so the net price is their real cost) and with VAT-charged input costs (you can claim VAT back). For construction craftsmen who are VAT payers, § 69(12)(a) applies — mandatory reverse charge between VAT payers. Sales to private individuals (B2C) are always at 23 % VAT if you are a VAT payer. If you exceed the €50,000 threshold, you must file a registration application within 20 days — you become a VAT payer from the first day of the following month. After registration, you must retroactively account for VAT from the day you should have been registered — a frequent source of trouble when discovered late.

Sample invoice

Invoice for a kitchen renovation for a private individual (non-VAT-payer)

No VAT columns — note „I am not a VAT payer“.

ItemQtyPriceVATTotal
Removal of old kitchen units1 h€18.000 %€18.00
Installation of new kitchen units (40 hours)1 h€22.000 %€22.00

Travel (3 days × 35 km × €0.30)1 pcs€31.500 %€31.50

This is an indicative example. The actual line items and totals depend on the specific engagement and supply type.

1FAKTURA for craftsmen solves four everyday problems. First: ad-hoc invoicing without registration — issue an invoice in 1 minute from the phone after the job, the client gets it by e-mail. Second: automatic numbering + the same supplier details on every invoice — no manual copying from last month. Third: a „no-VAT invoice“ template automatically drops VAT columns and adds „I am not a VAT payer“ — the generator keeps you in the right regime. Fourth: turnover tracking — if you approach the €50,000 threshold the generator warns you (in the full 1FAKTURA, not the free generator). UBL 2.1 XML for 2027 — Slovak Act 385/2025 Coll. does not impose the obligation on non-VAT-payers, but the format is available if you register later or if a B2B client prefers it.

Recommended plan

Which 1FAKTURA plan to pick.

A small craftsman with 5–20 invoices a month fits Plan Start (€0 forever) — usable lifelong while staying a non-VAT-payer with a relatively low turnover. Larger craftsmen with 20–50 invoices a month should consider Plan Lite — adding VAT threshold tracking and Pohoda / Money S3 exports. Craftsmen working B2B in construction with trickier reverse-charge calls will benefit from our free reverse-charge checker before every larger job.

Should I register as a VAT payer voluntarily?
+
It depends on the client mix. If you mostly invoice other VAT payers (B2B), it is advantageous — they can deduct VAT, so the net price is their real cost. If you mostly invoice individuals (B2C), it is disadvantageous — for them the price is 23 % higher with no deduction option. For retail / craftsmanship for individuals, registration is usually skipped.
Materials and travel — invoice them separately or in one line?
+
Separately, always. The tax office assesses each line on its own — if you bundle materials + labour + travel in one line, they may object and demand a breakdown. Practical approach: labour in hours, materials in pcs / kg / sets, travel in pcs (number of trips × agreed price per trip).
I lost attendance seasonally — can I catch up turnover in one month?
+
Yes, the tax office looks at annual turnover, not monthly swings. Gardeners, ski instructors, seasonal craftsmen typically earn 60–80 % of turnover in 4 months. But after 12 months (calendar year or rolling 12 months) the turnover is assessed — keep watch so you do not slip past the €50,000 threshold.
Customer identity — must I verify it before invoicing?
+
For B2C no. For B2B (the client claims to be a company with a VAT ID), verify the company ID + VAT ID via the Slovak Financial Administration register (free, financnasprava.sk). For a foreign B2B client from the EU, verify the VAT ID via VIES. Without verification the tax office may reject the exemption / reverse charge at audit and assess Slovak VAT.
What numbering should a small craftsman use?
+
Unique and continuous — typically the format YYYY-NNN (e.g. 2026-001, 2026-002, …). Reset to 001 at the start of each calendar year is acceptable. No duplicates (two invoices with the same number) or skipped numbers without explanation. The generator handles numbering automatically.
