Bookkeeping for agencies, IT firms, and service providers

Agencies, IT firms, and other service providers sell their time and expertise. We keep your books so that you can see what’s left over on each project, find every purchased service reflected in a client invoice, and never lose track of outstanding invoices.

Your industry

What sets your industry apart

For service providers, success depends on projects and hours worked. Revenue builds up over several weeks, is billed in installments, and is only settled at the end. To ensure that the monthly report is accurate, we allocate invoices and costs to projects or clients as you wish.

Agencies make purchases on behalf of their clients: advertising budgets with Google, Meta, or LinkedIn, as well as printing, production, and photography. These costs are passed on with or without a markup. Whether an advertising budget counts as your own revenue or as a pass-through item depends on your contracts, and the tax advisor assesses this. We make sure every purchase is matched by a client invoice and no budget goes unbilled. Invoices from major advertising platforms usually come from other EU countries without German VAT; we record them as directed by the tax advisor.

Agencies and IT firms work extensively with freelancers and subcontractors. Their invoices must be complete, and depending on how the work is arranged, there may be a question of whether someone is truly self-employed. Tax advisors or attorneys assess this; we make sure that contracts and invoices match and point out anything unusual. Anyone who regularly purchases design, copywriting, or photography services from self-employed individuals may also be required to pay the artists’ social security contribution. Your tax advisor will determine whether this applies to you; we compile the relevant invoices for the annual filing.

IT and software companies have their own specific patterns: recurring revenue from subscriptions and maintenance contracts, annual licenses paid in advance, payments via Stripe or other services, and cloud costs from providers abroad. We reconcile subscription revenue with payments processed by payment services and report prepayments separately so you can see which months they cover; your tax advisor handles the accruals in the financial statements. Your tax advisor determines whether in-house software should be recognized as an asset in the financial statements; upon request, we track costs and hours separately for each development project to provide the basis for this decision.

Travel expenses, entertainment, hardware, and software subscriptions often account for a large portion of service providers’ costs. These must be recorded in full and with the correct receipts so that the tax advisor does not have to adjust them downward later. For entertainment expenses, the occasion and attendees must be listed on the receipt; for travel, the purpose must be specified; and for software from providers abroad, VAT often has to be treated separately. We follow up on any missing information right away when posting.

For service providers, cash flow is often tighter than revenue figures might suggest. Salaries and freelancers are paid monthly, clients pay with payment terms of 30 days or more, and large projects tie up upfront costs for weeks. We track open items, show you every month who hasn’t paid yet, and, upon request, create a simple cash flow forecast. This way, you can see in advance when funds will be tight and can agree on progress payments or follow up with clients.

Receipts

Which receipts we need

  • Outgoing invoices from your invoicing software
  • Invoices from advertising platforms by campaign or client
  • Invoices from freelancers and subcontractors
  • Payout reports from Stripe or other payment services
  • Invoices from cloud providers, software subscriptions, and licenses
  • Travel expense reports and entertainment receipts

We import outgoing invoices from your invoicing software or as PDFs. Please forward incoming invoices via email or upload them to the client portal; invoices from advertising platforms and cloud providers can usually be forwarded directly to us.

Start

How we get started

To get started, we’ll clarify which program you use to create invoices, whether you’d like to view projects and clients separately, which freelancers work for you regularly, and for which clients you buy budgets. We reconcile the open invoices with the opening balances that your tax advisor posts from the last financial statements so that the list of open items is accurate from the very first month, and we agree on how bank statements and receipts get into the client portal each month. After that, you forward or upload incoming invoices, and the report showing open items is available in the client portal every month. If you’d like, we can review the figures together once a quarter.

With your tax advisor

We post the entries; the tax advisor decides the tax treatment

We set up the chart of accounts, record ongoing business transactions, run payroll, and prepare wage tax returns. Every month, we reconcile the accounts and pass the figures on to your tax advisor.

You hire the tax advisor directly, with your own contract and billing arrangement. If you don’t have one yet, we can put you in touch with our partner tax advisor, with whom we work closely.

Decisions on tax treatment are the tax advisor’s responsibility. We post entries so that they’re ready for the tax advisor to work with immediately.

How we work with tax advisors

The tax advisor handles the following on your behalf

  • Assessment of freelance work and bogus self-employment in consultation with an attorney
  • Advertising budgets as revenue or pass-through items
  • VAT on services to customers and from providers abroad
  • Artists’ social security contribution
  • Advance VAT returns, annual financial statements, and recognition of in-house developed software
  • Tax returns
