The cost of manual review

Every quarter, the same two hours per client.

Your team opens each client's accounting administration and works through the same manual checks: scanning transactions, verifying VAT codes, looking for missed deductions, assessing asset eligibility, cross-referencing prior periods. It is careful, necessary work — but it does not scale.

Transaction categorisation review ~45 min
Deduction eligibility check ~20 min
VAT code verification ~15 min
Asset assessment (KIA / MIA / EIA) ~15 min
Prior-period cross-reference ~10 min
Notes and issue flagging ~10 min
Total per client / quarter ~2 hours
Annual cost for a 40-client portfolio 320 hrs
The shift in workflow

Review suggestions, not transactions.

TaxWise connects to your accounting software, runs every check against Dutch tax legislation, and presents a shortlist of findings — each scored by confidence and tied to the relevant article.

Roadmap

Built around the practice. With the practice.

TaxWise is in active development. We are intentionally building with a small group of Dutch accounting firms — because the difference between a generic tool and one that fits your workflow comes from working with the people who use it every day.

Common questions

Answered before you ask.

Do we need to switch accounting software?

No. TaxWise connects to your existing accounting software via API and works alongside your current setup. The integrated accounting module coming after launch is optional.

How is this different from features in our accounting software?

Accounting software is built for bookkeeping. TaxWise is built specifically for the tax optimisation review — the work that happens after the books are closed and before the filing.

How accurate is it? What if a suggestion is wrong?

Every suggestion has a confidence score (green / amber / red) and a reference to the relevant belastingwet article. Your team validates each finding — TaxWise never auto-files anything.

What happens with our client data?

All data is processed within EU infrastructure. We are GDPR-compliant and provide a Data Processing Agreement before any pilot begins. No client data is used to train models for other firms.

How long does setup take?

For design partners, we handle the integration ourselves. Onboarding takes one session of approximately 60 minutes.

What happens after the design partner phase?

Design partners shape the product during development and receive priority access afterwards, including the integrated accounting module at no additional cost — for as long as you remain a customer.
