Papierkram

B2C/SMB SaaS, invoicing & accounting for freelancers

Papierkram had thousands of free signups every month from Google Ads. Their invoicing and bookkeeping tool for freelancers was attracting users, but less than 4% upgraded to a paid plan.

Use case

B2C/SMB direct payment

The situation

Thousands of signups. Almost nobody paying.

The account optimized for signups, not purchases. Google found people who create free accounts to send one invoice, not people who need a recurring tool and will pay €8-24/month. Less than 4% upgraded to a paid plan.

What we found

4 structural problems in the account

Primary conversion was 'free signup' instead of 'paid plan activation.'

Broad match pulling 'free invoice template' and 'free accounting software' searches with zero purchase intent.

No remarketing for trial users who didn't convert within 14 days.

All traffic sent to homepage instead of pricing page with feature comparison.

What we did

From signups to paying customers

Week 1

Conversion tracking overhaul

New conversion actions: trial start, paid activation, plan upgrade with values assigned to each.

Week 2

Campaign restructure

Built campaigns around commercial keywords ('invoicing software for freelancers', 'accounting tool small business pricing'). Free-intent keywords killed.

Week 3

Remarketing & landing pages

Remarketing launched targeting trial users at day 3, 7, 12. Dedicated landing pages with pricing and plan comparison.

Week 4+

Value-based optimization

tROAS bidding based on plan value. Continuous landing page A/B testing.
