Hiring a digital marketing agency in Poland: what UK and German companies should check

Hiring a digital marketing agency in Poland works much like hiring one at home, with four practical differences: a one-hour time gap with the UK (and none with Germany), a contract usually written in English, invoices in EUR or GBP, and VAT handled through the reverse charge instead of being added to the invoice. Settle those four in the first call and the rest is the same as any agency relationship: clear goals, access to your data and a regular review.

This guide is for marketing managers and owners in the UK and Germany, including anyone who searched for “Online-Marketing Polen” and prefers to read in English. It covers how the work runs day to day, what belongs in the contract, how invoicing and VAT work, the questions to ask before you sign and the warning signs that should end the conversation.

We are LineUp, an agency based in Wrocław, and we work with clients in Poland, Germany, France, the UK and Turkey. What follows is how cross-border work actually runs, including the parts that tend to trip people up. If your main question is price, we have covered that separately in how much SEO costs in Poland vs the UK vs the Czech Republic.

How the working day lines up across CET and UK time

Poland runs on Central European Time (UTC+1) in winter and Central European Summer Time (UTC+2) in summer. The UK and Poland change their clocks on the same weekends, so the gap is always one hour: 10:00 in London is 11:00 in Wrocław. Germany and France share Poland’s time zone, so for clients there the gap is zero.

For a UK client almost the whole working day overlaps. A Polish team working 9:00 to 17:00 is available from 8:00 to 16:00 UK time, so book late-afternoon calls before 16:00 your time and expect non-urgent messages sent after that to be picked up the next morning.

How requests flow matters more than the clock. Agree on these at the start:

• One shared channel for day-to-day questions, whether that is Slack, Teams or email, so requests don’t scatter across several inboxes.
• A response window for normal requests, for example the same working day, and a separate route for real emergencies such as a broken checkout or a suspended ad account.
• Who signs off on your side. Most delays in cross-border work come from waiting for approval, not from the time difference.

Contracts: what to get in writing before work starts

Most Polish agencies that work with foreign clients will offer a contract in English. Read it as you would a UK or German agency contract, paying particular attention to the points below. They are the ones that cause disputes when a relationship ends.

Ownership of accounts, data and content

Your Google Ads account, Google Analytics 4 property, Search Console, Google Business Profile, Meta Business Manager and LinkedIn Campaign Manager should all be registered to your company, with the agency added as a user. The same applies to landing pages, copy and creative you have paid for. If an agency wants to run your ads from its own account, ask what happens to the account history if you leave. Usually it stays with them, and you start from zero.

Term, notice and scope

Check the minimum term, the notice period and exactly what the monthly fee covers. A line that says “SEO” or “PPC management” with no list of deliverables makes it hard to judge whether you are getting what you pay for. Attach a short scope document to the contract listing the monthly deliverables and what counts as extra work.

Data protection

If the agency will handle personal data for you, such as CRM exports for ad audiences or form submissions, you need a data processing agreement under GDPR. Poland is in the EU, so German and French clients sit inside the same framework as their agency. UK clients should ask whoever handles data protection internally to confirm the transfer terms. If the contract exists in two languages, it should also state which version is binding.

Invoicing in EUR or GBP, and how reverse-charge VAT works

Polish agencies can invoice in złoty, euros or pounds, so agree the currency in the contract. If you are invoiced in your own currency, the exchange-rate risk sits with the agency. If you are invoiced in złoty, it sits with you, and your bank’s conversion fees come on top. For German and French clients, a euro invoice paid by SEPA transfer is the simplest arrangement.

VAT is where foreign clients most often get confused, because a Polish agency invoicing a business abroad usually adds no Polish VAT at all.

German, French and other EU business clients

Services sold between businesses in different EU countries normally fall under the reverse charge. The European Commission’s Your Europe guidance on cross-border VAT explains that when you buy services for business purposes from another EU country, you declare and pay the VAT yourself at your own country’s rate, and can usually deduct it in the same return. The Polish invoice shows no VAT, both companies’ VAT numbers and a reverse-charge note. The agency will check your VAT number in the EU’s VIES database before invoicing, so have it ready.

UK business clients

Since Brexit the UK applies its own rules, but the effect is similar. HMRC’s VAT Notice 741A explains that when a UK business receives most business-to-business services from a supplier based outside the UK, the place of supply is the UK and the customer accounts for the VAT under the reverse charge. If you can reclaim that VAT in full, it has no net cost. The notice also flags a point for smaller firms: if you are not VAT registered, services you receive from overseas suppliers count towards the UK registration threshold.

Language, reporting and who you will actually talk to

Ask early who will be on your calls and who writes your reports. In a good setup you speak to the people doing the work, not only to an account manager relaying messages, and the working language is agreed rather than assumed.

The harder question is copy for your market. If the agency is writing German ads, landing pages or blog posts, ask who writes them and who checks them. A native speaker should write or at least review anything a customer will read. The same goes for UK English, where spelling and tone differ from US English and buyers notice.

A reporting rhythm that works across borders

• A live dashboard, usually in Looker Studio, that you can open any time without asking.
• A written monthly report tied to business numbers such as enquiries, sales and cost per lead, not only rankings and clicks.
• A fortnightly or monthly call, and a quarterly review where you look at strategy rather than tasks.

What to ask in the first call

The first call tells you more than any proposal document. These questions are worth asking any agency, and they matter more when you can’t easily drop into its office:

1. Who will work on my account each week, and will I speak to them directly?
2. Which clients do you have in my country or sector, and could I speak to one of them?
3. Who writes and reviews copy in my language?
4. What do you need from us in the first 30 days, in terms of access, approvals and information?
5. How will you track conversions, and what exactly will the monthly report show?
6. What happens to our accounts, data and content if we stop working together?
7. What is the notice period, and what work falls outside the monthly fee?
8. What would you advise us not to spend money on?

The last question is a good filter. An agency that can name things you should skip has probably looked properly at your business. You can see the range of work a full-service team covers on our services page, but a good first call should narrow that list down, not expand it.

Red flags when hiring an agency abroad

Most of these apply anywhere, but distance makes them harder to spot.

• Guaranteed rankings. Google’s own guide on whether you need an SEO states that no one can guarantee a number one ranking. A contract that promises one is a sales line, not a commitment.
• Ad accounts in the agency’s name. If you cannot see the account, you cannot check what was spent or keep the history.
• Requests for your passwords. Every major platform lets you add an agency as a user with its own login. Sharing your password is a security risk and a sign of sloppy process.
• Reports with no business numbers. Impressions and rankings on their own do not tell you whether the work is paying for itself.
• No named people. If you only ever meet a salesperson, you don’t know who will do the work.
• A contract only in Polish. Reputable agencies working abroad will provide an English version and state which language is binding.

If you want to see how a Polish team reports results, read a published case study rather than a sales deck. Ours include a local SEO project for a Wrocław language school, with the method and numbers set out in full.
