Compact invoice template for Wholesale / Draft orders

Hello,

my client is on the Basic plan and would like to be able to process wholesale orders.

I have 2 questions:

  1. which wholesale app would you recommend

  2. is there a way to customize invoice template to display a table similar to this spreadsheet, with variants running across, instead or having each variant on its own line? Otherwise, if there is an order for 100 items, 10 products x 10 variants, then the invoice ends up being super long and confusing.

Thank you!

Marianna
