What you need as a freelancer

Exactly enough. Nothing more.

Most bookkeeping tools make you pay for buttons you'll never touch. This does the things that actually matter. Well. Don't use something? Switch it off with one toggle. Built for freelancers (zzp'ers) in the Netherlands.

01

Hours

Log your hours per client and project. By week, by day, done. The hours counter shows how you're doing on the 1,225-hour criterion (urencriterium).

02

Mileage

A trip log the way the Dutch tax office asks for it: date, from and to, purpose and your odometer reading.

03

Rates

Your own hourly rate and mileage allowance per client. The app does the maths.

04

Clients

All your clients and projects in one place. Archive what's finished.

05

Quotes

Need a quote first? Create it, print it, and once your client agrees, turn it into an invoice in one click.

06

Invoices

One click turns your open hours and mileage into an invoice, with an hours specification attached.

07

Products

Selling goods or charging for materials? Save them once, with or without VAT, and add them to an invoice in one click.

08

VAT return

Your VAT (BTW) prepared per quarter, box by box. English labels, Dutch rules. Reverse charge in construction, the KOR or VAT-exempt? Set it once and your invoices are right.

09

Income tax

Your profit and an income-tax estimate, including the Dutch self-employed deduction and SME profit exemption.

10

Assets

Laptop, phone or company car? The app depreciates them across the years.

11

Expenses and bank

Record your expenses and attach the photo of the receipt or the PDF. Or import your bank statement (CSV, CAMT.053 or MT940): the app creates whatever is missing, with a suggested category and VAT rate.

Who it's for

Sound like you?

DIY Administration is made for freelancers with a sole proprietorship (eenmanszaak). A BV? It's not built for that.

Freelancer

Hours per client and project. Your quote becomes an invoice in one click, in English too.

Tradesperson

Save your materials once and add them to your invoice. Subcontracting in construction? Tick VAT reverse-charged. Snap your receipts with your phone.

Healthcare

Exempt from VAT? Choose it once. Your invoices go out without VAT and your costs count including VAT, because you can't reclaim it. Track your mileage and hours as usual.

Next to a job

Using the KOR? Your invoices go out without VAT, with the statement that goes with it. Not reaching 1,225 hours? Untick it, the rest keeps adding up.

Interim

Long assignment, one client? Every month your invoice from your hours in one click, with the hours specification attached.

Up to date in three steps

Your admin adds up. No course required.

1

Enter what you did

Hours, mileage and costs. A few minutes a week, that's all.

2

Invoice in one click

The app builds your invoice and specification from what's open. Save as PDF, email it, done.

3

VAT and tax ready to go

Your VAT each quarter, and your profit and tax for the year. All you do is submit.

Why this exists

I was so done with the hassle.

If you're self-employed, you know the drill. Every quarter, those evenings with receipts, bank statements and a spreadsheet that never quite adds up. Then the meeting with the accountant. That bill. And the hours you put in yourself, which nobody pays you for.

I'd had enough. So I built what I wanted myself.

No more spreadsheets. No more meetings with a bookkeeper. You simply attach a photo of the receipt or the PDF of the invoice to the entry. You import your bank statement, and the app creates whatever is missing, with a suggested category and VAT rate. You check it. After that, your quarterly VAT and your profit are ready and waiting.

The sums? The app does them. I'm back to what I'm good at: my own work.

I'd like that for you too. And if there's a feature you miss? Well, then we'll build it in!

Why honest

No fine print. No surprises.

Your data stays yours

Everything stays with you, in your own browser. No data hunger. The app makes a backup every day. Working in Chrome or Edge? Link a folder in iCloud or OneDrive, and everything is stored there too.

On your phone too

Log your hours or snap a receipt, wherever you are. Good to know: your phone and your laptop don't share your data automatically. Work on one device, or move your data with a backup.

Stopping? Everything stays yours

Even after your trial, your data stays put, and you download it whenever you like.

No features you don't get

Built for freelancers, not for accountants. Don't need something? One toggle and it's out of sight.

One honest price

No tiers, no "from", no charge per invoice. You know what you pay.

Honest is honest: the app prepares your VAT return and gives an income-tax estimate. You file the official return yourself with the Dutch tax office (Belastingdienst). We make sure everything is ready, you hit submit.

Frequently asked

Just one more thing.

What is DIY Administration?

Online bookkeeping software for freelancers in the Netherlands. You keep track of your hours, mileage, invoices, expenses and VAT in your own browser. It costs € 50 a year or € 5 a month, excluding VAT, and you try it free for 7 days first. In Dutch it's called DHZ Boekhouding.

Do I need to understand bookkeeping?

No. That's the whole point. You enter what you did (hours, mileage, costs) and the app handles the rest. No debit, no credit, no jargon.

How does the free trial work?

You use DIY Administration free for 7 days, with every feature. No payment details needed. After that you choose: € 50 in one go, or € 5 a month. Prices exclude VAT.

What's the difference between € 50 and € 5 a month?

Both give you 12 months of access. Pay once and it's € 50. Pay monthly and it's 12 × € 5, € 60 in total. All prices exclude VAT. You pick what suits you.

Does the app read my receipts automatically?

No. You attach the photo of your receipt or the PDF of the invoice to the entry, so you can always find it. You enter the amount and VAT yourself. Want to type less? Import your bank statement. The app creates the expenses that are still missing, with a suggested category and VAT rate. You check it.

Which bank statements can I import?

CSV, CAMT.053 and MT940. All major Dutch banks let you download these, usually under Downloaden or Exporteren (Download or Export).

Does the app file my VAT and tax return?

The app gets everything ready: your VAT per quarter and your profit-and-tax overview for the year. You file the official return yourself with the Dutch tax office. That takes a few minutes, because it's all prepared.

Is it made for internationals in the Netherlands?

Yes. Switch the app to English with one button, and your invoices go out in English too. It's built around the Dutch rules you deal with as a freelancer here: VAT (BTW), income tax and the self-employed deductions.

I use the KOR. Is it still useful?

Yes. Choose the small business scheme (KOR) in Settings. Your invoices then go out without VAT, stating that you use the KOR. Your costs count including VAT for your profit, because you can't reclaim that VAT. The VAT menu disappears, the rest keeps working.

I'm exempt from VAT, for example in healthcare. Does it work?

Yes. Choose it once in Settings. Your invoices go out without VAT, stating that the exemption applies. Your costs count including VAT for your profit. Check with the Dutch tax office whether the exemption applies to your work.

I'm a subcontractor in construction. Can I reverse-charge VAT?

Yes. Tick VAT reverse-charged on your invoice and fill in your client's VAT number. The invoice then shows no VAT, but does show 'VAT reverse-charged' and your client's VAT number. In your VAT return the amount goes in box 1e.

Does it work for my BV?

No. DIY Administration is made for the sole proprietorship (eenmanszaak). It works with the self-employed deduction, the SME profit exemption and income tax. A BV has different rules.

I also have a salaried job. Does it work?

Yes. Not reaching 1,225 hours, or working more hours in your job? Untick the hours criterion. Note: the tax estimate assumes your profit is your only income. With your salary on top, you usually pay more on your profit. So set a bit more aside.

Does it help with the hours criterion?

Yes. The hours counter shows how many hours you've logged this year. For the self-employed deduction (zelfstandigenaftrek) you need at least 1,225 hours a year, and more time in your business than in any job.

Where is my data stored?

With you, in your own browser. The app makes a backup every day, and one button makes one yourself. On another computer, you load that backup there. Preferably work in Chrome or Edge: Safari clears data from sites you haven't opened for a week.

What happens if I stop?

Your data stays yours. It stays in your browser and you download it whenever you like. Keep your backup safe: you have to keep your records for 7 years.

Will it work on my computer and my phone?

If you have a browser, it works. Mac, Windows, Chromebook and your phone. Note: your phone and your computer don't share your data automatically. Work on one device, or move your data with a backup.

Who makes DIY Administration?

I do, Patricia Heemskerk. A freelancer myself, I built the app because I was done with spreadsheets and accountant bills. DIY Administration is a product of Kus van Invloed.
