Your Firm Loses Hours
Every Week
to Repetitive Admin
CodeHunter Lab builds custom automation systems for accounting firms in the Netherlands — automating invoice processing, client onboarding, deadline reminders, and financial report generation. No generic software. No vendor dependency.
Although we are located in the Netherlands, our main method of communication is English. However, we also offer and create systems in Dutch, as we have a specialist who reviews content in that language.
The Real Cost of Running an Accounting Firm in 2026
Manual invoice processing consumes billable hours
Your team enters invoices manually, checks VAT codes, and exports to Exact Online or Twinfield. Every manual step is time your accountants could spend on advisory work that actually generates margin.
Tax deadlines managed with spreadsheets and memory
Missed deadlines mean penalties for clients — and damaged trust for your firm. Without automated deadline tracking and client reminders, you are one busy month away from a costly mistake.
Client onboarding is slow and inconsistent
A new client takes 2–3 weeks to get onboarded because forms, KYC checks, and document requests are handled manually and inconsistently.
Reports take days instead of minutes
Monthly management reports require extracting data from multiple systems, reformatting in Excel, and manually emailing. Automation delivers real-time dashboards.
Your tools don't talk to each other
Exact Online, your CRM, email, and client portal are disconnected. Every transfer between systems is a manual step and a potential data error.
Pending document follow-up falls through the cracks
You wait weeks for clients to send bank statements or receipts. Without automated reminders, your team ends up chasing them manually — a poor use of specialised time.
What We Build for Accounting Firms
We are not a software vendor. We build and integrate the systems your firm already has — or needs — so they work together automatically.
Invoice Processing Automation
We connect your document intake (email, portal, scanner) to Exact Online or Twinfield via API. Invoices are automatically categorised, VAT codes applied, and posted — your accountants review exceptions, not every line.
→ 80% reduction in manual entry time.
Deadline Reminder System
We build a deadline engine that tracks BTW, Vpb, and IB filing dates for every client. Automated reminders go to clients (requesting documents) and your team (internal alerts) — with weeks to spare.
→ Zero missed deadlines. Clients prepared on time.
Client Onboarding Automation
Client signs agreement → automated KYC document request → completion tracking → welcome email with portal access → account set up in your systems. Your team only handles exceptions.
→ Onboarding from 3 weeks to 3 days.
Real-Time Reporting Dashboards
We connect Exact Online, Twinfield, or Moneybird to a live dashboard showing P&L, cash flow, outstanding debtors, and VAT position for each client. Automatically updated. Accessible anytime.
→ Management reports in seconds, not days.
Document Request & Follow-Up Automation
When a client document is pending, an automated sequence triggers: email reminder on day 1, WhatsApp on day 5, escalation on day 10. Your team only gets notified if follow-up fails.
→ Document delivery time reduced by 60%.
CRM & Client Communication Hub
We connect your client database to a CRM that tracks every interaction, upcoming renewal, and upsell opportunity. Annual account reviews, service upgrade offers, and satisfaction checks go out automatically.
→ Higher client retention and increased average revenue per client.
What This Looks Like in Practice
Monthly Close Automation
01Last day of the month → the system checks all clients for missing documents → automated follow-up sequences launch → Exact Online entries are pre-filled from incoming invoices → your team reviews a clean exceptions report.
BTW Deadline Sequence
026 weeks before the deadline → client receives document checklist → 3 weeks before → second reminder if documents are pending → 1 week before → internal alert to the assigned accountant → everything tracked automatically.
New Client Onboarding Flow
03Client signs engagement letter → automated email sends KYC form and document list → documents verified → account created in Exact Online → welcome pack delivered → onboarding marked complete in CRM.
Annual Account Review Trigger
0412 months after onboarding → the system generates an account summary → sent to the assigned accountant for review → personalised review invitation sent to the client → meeting booked via calendar link → upsell opportunities identified.
