We run bookkeeping digitally, simply and individually – and bring expertise exactly where it counts.
Our services
We start with bookkeeping — the heart of every clean finance operation. The modules you actually need plug in around it. Only as much as necessary, expandable at any time.
Our Partners
Who it's for
Focused on companies with around 5–50 employees, across industries. You see clean numbers as a value driver — not as a tedious obligation.
DOES THIS SOUND LIKE YOU?
STATUS QUO
Bookkeeping is still half manual. Receipts and routine eat up time, there's no real-time overview — and automation potential stays untapped.
HOW Z83 APPROACHES IT
What you get
No empty promises. For every point, we show why it holds up.
A fiduciary who only posts entries
Highly qualified team members — not back-office processing. A dedicated contact with short response times.
Standard software that doesn't fit
In-house developers build and adapt systems per client — no off-the-shelf standard package.
Manual routine that eats time
AI handles recurring receipt work. Our experts step in where real judgment is required.
Numbers that arrive too late
Digital, continuous receipt flow instead of delayed posting — you see the current status at any time.
Missing internal resources
Fiduciary, tech and development under one roof. You don't build internally or coordinate interfaces.
How the switch works
Up and running in around 4 weeks — without your day-to-day grinding to a halt. You hand over access, we handle the rest in the background.
THE SWITCH · STEP BY STEP
01
We explore together whether it's a fit. No obligation.
02
You know what to expect — before you decide.
03
You give us access. That's all you need to do.
04
We implement and prepare everything — depending on your receipt flow, you only upload receipts and approve payments in e-banking.
05
You're relieved. We run, you steer.
06 · ONGOING
We coordinate your accounting processes, bring in expertise and support where needed. The work is tailored individually.

Case Studies
The experts behind it
Accounting software defines processes. Fiduciary work brings expertise. Z83 is both.
«Fiduciaries who develop software – and developers who understand accounting. At most fiduciaries, digitalisation stops at the software they bought. For us, that's where it begins.»
Frequently asked questions
It depends on your receipt volume and scope – that's why we don't put a fixed price sticker on it, but give an honest estimate. In 2 minutes the calculator gives you a first ballpark; in the initial call you get the exact number. Usually the expensive part isn't switching – it's not acting.
Intentionally light for you: in about 4 weeks you're switched over without your day-to-day standing still. You hand over access – we handle setup, migration and coordination in the background.
Only as briefly as needed. We plan the transition so parallel running stays minimal and the cutover has a clear date – so you don't live in two worlds for long.
We migrate in a structured way, check critical processes like payroll and master data, and closely support go-live. You have a clear contact person – and we step in before a detail becomes a problem.
From ongoing bookkeeping and digital receipt flow to payroll, tax, reporting and CFO services – modular, based on what you actually need.
Yes, if you want to work digitally. Our focus is service companies with roughly 5–50 employees – across industries, with processes that scale with you.
