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 reporting. No generic software. No vendor lock-in.
Although we are located in the Netherlands, our main method of communication is English, as our tech team speaks English. However, we also offer and create websites in Dutch, since we have a specialist who proofreads Dutch content.
The Real Cost of Running an Accounting Firm in 2026
Manual invoice processing eats billable hours
Your team manually enters invoices, checks VAT codes, and exports to Exact Online or Twinfield. Each manual step is time your accountants could spend on advisory work that actually generates margin.
Tax deadlines managed by 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 onboard because forms, KYC checks, and document requests are handled manually and inconsistently across your team.
Reporting takes days instead of minutes
Monthly management reports require pulling data from multiple systems, reformatting in Excel, and emailing manually. Automation delivers real-time dashboards instead.
Your tools don't talk to each other
Exact Online, your CRM, email, and client portal are disconnected. Every handoff between systems is a manual step and a potential data error.
Follow-up on outstanding documents falls through the cracks
You wait weeks for clients to send bank statements or receipts. Without automated reminders, your team ends up chasing manually — a poor use of specialist time.
What We Build for Accounting Firms
We are not a software vendor. We build and integrate the systems your firm already owns — or needs — so they work together automatically.
Invoice Processing Automation
We connect your document intake (email, client portal, scan) to Exact Online or Twinfield via API. Invoices are automatically categorized, VAT codes applied, and entries posted — your accountants review exceptions, not every line.
→ 80% reduction in manual invoice entry time.
Deadline & Compliance Reminder System
We build a deadline engine that tracks every client's BTW, Vpb, and IB filing dates. Automated reminders go to clients (requesting documents) and to your team (internal alerts) — weeks in advance, not days.
→ Zero missed deadlines. Clients prepared on time.
Client Onboarding Automation
New client agreement signed → automated KYC document request sent → completion tracked → welcome email with portal access → account set up in your systems. Your team only touches exceptions.
→ Onboarding time 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 every client. Updated automatically. Accessible anytime.
→ Management reports in seconds, not days.
Document Request & Chase Automation
When a client document is overdue (bank statement, receipt batch, contract), an automated sequence is triggered: reminder email on day 1, WhatsApp on day 5, escalation on day 10. Your team is notified only if the chase fails.
→ Document turnaround time cut 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 check-ins go out automatically.
→ Higher client retention and increased average revenue per client.
What This Looks Like in Practice
Month-End Close Automation
01Last day of month → system checks all clients for missing documents → automated chase sequences start → Exact Online entries are pre-populated from incoming invoices → your team reviews a clean exception report rather than chasing and entering data manually.
BTW Deadline Sequence
026 weeks before BTW deadline → client receives document request checklist → 3 weeks before → second reminder if documents outstanding → 1 week before → internal alert to assigned accountant → all tracked automatically, no manual follow-up required.
New Client Onboarding Flow
03Client signs engagement letter → automated email sends KYC form and document checklist → completed documents verified → Exact Online account created → welcome pack delivered → onboarding marked complete in CRM. Fully automated from signature to active client.
Annual Account Review Trigger
0412 months after onboarding → system generates account summary → sends to assigned accountant for review → personalised review invitation sent to client → meeting booked via calendar link → upsell opportunities flagged based on client profile.
