Tax advice and accounting for agencies, service providers and SaaS

Retainers, prepaid budgets and revenue share no longer end up in Excel lists
Payroll, onboarding and offboarding take too much operational time
Your BWA arrives too late or does not show which clients, teams and services are profitable

200+ clients. 100% e-commerce focus on Amazon, Shopify, D2C and multichannel.

Why do agencies and SaaS companies get held back by their accounting?

Growth rarely fails because of sales. It fails because nothing internal keeps up any more, least of all the numbers.

Recurring revenue does not fit standard bookkeeping.

Retainers, prepaid budgets and revenue share need clean logic, otherwise your reporting becomes guesswork. A prepayment for next year is not yet this year's revenue. We accrue that cleanly every month.

Excel becomes your secret finance system.

As soon as prepayments and accruals move into sheets, your team loses time and you lose control. A table that gets updated quarterly is not accounting. With us it runs monthly in the system.

Clients abroad? We clarify who owes the VAT, including reverse charge.

Freelancers in Portugal, devs in India, payments via Wise or Payoneer? No problem. We book reverse charge correctly and file your services to EU clients on time.

Payroll is not negotiable.

If salaries or questions get stuck, trust in the team suffers and you lose focus. That is why payroll is part of the engagement: filings to the tax office and health insurers, mini-jobs, bonuses and benefits all run digitally through DATEV.

The tool stack grows, the processes do not.

Invoicing software, receipt tools, cards, subscriptions: without clean interfaces, every month turns into a manual rescue operation. We connect Lexware, sevdesk, Stripe, PayPal, GetMyInvoices, Pleo and Moss directly.

A BWA you cannot decide on is a waste of time.

You need figures you can steer hiring, runway and profitability with, not figures for the file.

Excellent bookkeeping 🙏🏼 I’ve worked with several tax advisors in the past. After generating several million euros in revenue and filing countless VAT returns, tax is finally starting to be enjoyable. Definitely the right place to go for anyone who has just made their first million and needs support with e-commerce, Pan-European FBA and Amazon. Excellent!

Common questions for agencies and SaaS

Here you will find answers to the most common questions about working together, switching and our services.

Book an introductory call
Free & no obligation
15 minutes
No preparation required

How are retainers and prepaid budgets accrued?

A prepayment is not yet revenue. It is spread over the term, while the VAT is already due on payment. That is why your BWA differs from your account balance, and that is exactly what we map cleanly.

When does reverse charge apply for clients abroad?

For services to businesses in other EU countries you invoice without VAT, and the client accounts for the tax. Conversely, you owe the tax on tools and freelancers from abroad. We book and file both for you.

How are SaaS subscriptions to consumers taxed?

In the customer's country. If you sell regularly to consumers in the EU, this runs centrally through OSS instead of registrations in every country. We build OSS into your monthly routine.

How quickly can I switch?

Typically within 4 weeks. Your effort: under 30 minutes. We handle the communication with your previous tax advisor.

How does payroll work for working students and freelancers?

We run working students digitally through DATEV, including all filings. With freelancers we check with you whether the arrangement clearly counts as self-employment, so no back payments come up later.

Which systems do you connect?

DATEV plus your invoicing and payment systems: Lexware, sevdesk, easybill, Stripe, PayPal, GetMyInvoices, Pleo, Moss. All through interfaces instead of exports, so receipts stay in their original form and remain analyzable at any time.

Technical Background: Agencies and SaaS

The tax basics for services and international teams.

Accrual accounting, Section 252 (1) no. 5 HGB and Section 250 (2) HGB

Expenses and income must be allocated to the fiscal year regardless of when payment occurs. A prepayment for the next year is not yet income but a deferred income item.

VAT on prepayments, Section 13 (1) no. 1 letter a sentence 4 UStG

For VAT purposes, the tax arises upon the prepayment. Commercial and VAT law run separately here, which is why the management report differs from the account balance.

Place of supply, Section 3a (2) and (5) UStG

For services to businesses in other EU countries, the place of supply is where the recipient is located. Electronically supplied services to consumers are taxed at the customer's residence, above 10,000 euros EU-wide via OSS.

Reverse charge, Section 13b UStG, Section 22 (2) no. 8 UStG and Section 18a UStG

For services received from abroad, the recipient owes the tax and must record it separately. Intra-Community services must be included in the recapitulative statement by the 25th day.

Small business exemption, Section 19 UStG

Since 2025, the thresholds are 25,000 euros in prior-year revenue and 100,000 euros in the current year. If the 100,000 euros is exceeded, the exemption ends immediately from the sale that crosses the threshold.

Recording and retention, Section 146 (1) AO and Section 147 (2) and (3) AO

Entries must be recorded individually, completely, correctly, in a timely manner, and in an orderly fashion. Documents remain in original format and machine-readable; books ten years, accounting documents eight, other records six.
