Invoicing and Tax Prep Reduced from Days to Hours

Overview

As marketplaces grow, invoicing complexity often increases faster than revenue. New partners, new geographies, and new transaction types quickly turn billing into a time-consuming, high-risk process that drains small teams.

For yhangry, a fast-growing B2B2C marketplace operating across the UK and the US, invoicing had become one of the most operationally painful parts of the business. Menza transformed this process from a multi-day ordeal into a task that could be completed in a single morning.

Customer Context

yhangry operates a B2B2C marketplace connecting private chefs with customers, often through partners such as vacation rental platforms.

This model creates complex invoicing requirements, including:

• Gross merchandise value tracking
• Sales tax calculations
• VAT calculations in the UK
• Clear breakdowns by partner and channel

All of this had to be handled by a lean team of just three people responsible for running the entire B2B2C function.

The Problem: Invoicing Became a Growth Bottleneck

As transaction volume increased, invoicing prep became increasingly painful.

Before Menza:

• Invoicing prep took two full days each cycle
• Team members had to manually pull data from multiple systems
• Calculations required careful cross checking
• Cognitive load was high, and mistakes were easy to make

Beyond the time cost, the process was mentally draining. In a fast-growing company, spending days every month just preparing invoices was not sustainable. It pulled focus away from strategy, partners, and growth.

Hiring more people to solve this was not an option.

How Menza Helped: Pre-Calculated, Ready-to-Use Numbers

Menza changed the workflow entirely.

Instead of manually assembling invoicing data, the team used Menza to calculate and surface:

• GMV by partner and period
• Sales tax amounts
• VAT amounts for UK transactions

These numbers were available upfront, already structured and ready to use before the invoicing process even began.

As one team member described it:

Something that used to take days now takes just the morning of invoicing. — Rosie Willis, GTM & Product

Menza removed the need to stitch together spreadsheets, double-check formulas, or mentally track edge cases.

Outcome: Faster Cycles, Less Stress, Same Team

The impact was immediate and compounding:

• Invoicing prep was reduced from two days to a single morning
• Error risk dropped significantly
• The team stayed lean despite increasing transaction volume
• Stress around invoicing cycles disappeared

Most importantly, the team regained time and mental space to focus on higher-value work rather than administrative overhead.

Why This Matters

Invoicing and tax prep are rarely seen as strategic functions, but when they break, they slow everything else down. For lean teams, these processes can quietly cap growth or lead to burnout.

Menza lets lean teams operate at enterprise scale.

Menza allowed yhangry to operate with the discipline and reliability of a much larger organization, without adding headcount or complexity.
