Receipts by email, follow-ups by phone, deadlines in your head — tax advisors still manage too much manually. How a custom client portal transforms the daily routine.
The Email Problem at Tax Firms
It's March. Tax filing season. And your inbox is exploding.
"Attached are the receipts for 2025." — An email with 47 unsorted photos attached. Three of them are selfies that were sent by accident.
"Where do I find the certificate?" — The third follow-up this week.
Klingt nach deinem Problem?
"Could you call again briefly?" — "Briefly" means 20 minutes.
Sound familiar? You're not alone. 78% of tax advisors name receipt collection as the most time-consuming non-technical process in their firm (BStBK survey 2025).
What's Tedious and What Could Be Simple
Receipt Upload
Today: Client sends a scan/photo by email. The firm sorts, renames, and files it. Per client: 30 minutes a year. With 300 clients: 150 hours.
With a portal: Client photographs a receipt, uploads it, AI categorizes automatically. Time: 2 minutes per client. Savings: 140+ hours per year.
Deadlines & Follow-Ups
Today: Excel spreadsheet with deadlines. Phone call when documents are missing. Email ping-pong for follow-up questions.
With a portal: Automatic deadline reminders to clients. Follow-up questions as chat within the portal. All information in one place.
Document Delivery
Today: Tax assessment by mail or email. Client can't find it later. "Could you send that again?"
With a portal: All documents centrally accessible. Tax assessments, advance payment notices, calculations. Anytime, from anywhere.
Why DATEV Unternehmen Online Isn't Enough
DATEV users know DATEV Unternehmen Online. It's... functional. But:
- UX from the 90s: Clients who aren't tech-savvy struggle with the interface
- Rigid: Your firm's processes have to adapt to DATEV
- Expensive: DATEV licenses quickly add up to €1,000+/month
- No branding: It's a DATEV portal, not your firm's portal
For clients under 40 who use Revolut and Notion, DATEV feels like time travel. Not in a good way.
What a Modern Client Portal Looks Like
Simple as a Banking App
Client opens the app, sees a dashboard: What's still missing? What's in progress? What's done? One glance, everything clear.
Mobile Receipt Upload
Take a photo, upload, done. AI recognizes the receipt type. No more emails with 47 attachments.
Chat Instead of Phone Calls
"Is the Media Markt receipt business-related?" — A quick question in chat. The client responds when it suits them. No scheduling issues.
Deadline Management with Push Notifications
"Please submit by March 15" — automatic reminder. You don't have to chase people, the system does it.
Your Branding, Your Portal
Your logo, your colors, your name. Clients see youryour firm, not a third-party vendor.
The Firm Effect
Firms that deploy a good client portal report:
- 60% less email volume
- 40% faster receipt collection
- Significantly higher client satisfaction (fewer follow-ups, more transparency)
- More attractive to new, younger clients who expect digital processes
And Here's Where It Gets Interesting
Having a custom client portal built by an agency? €30,000–80,000. Unrealistic for a solo practice.
SaaS solutions like Taxdoo, GetMyInvoices, or Kanzlei.land? Okay, but limited customization and yet another platform dependency.
What nopex Does Differently
nopex builds your client portal — tailored to your firm. Not another SaaS tool with fixed features, but a solution that maps exactly to your workflows.
You describe how you work: How do receipts come in? What follow-up questions do you regularly ask? What do your clients need? nopex understands this and builds a portal that feels like a 5-person development team spent months on it.
The difference: It takes weeks instead of months, costs a fraction — and it's yoursyours. Your firm, your branding, your processes.
Because tax advisors should be advising clients. Not sorting emails.
