Product variant app with price add-ons

[Beercis]

Hello!

Newcomer here.

We are custom sportswear brand offering personalised design sports gear for teams. I am using Shopify to create custom stores for teams. Stores are created as specific collections and I have been able to find workarounds for most of my needs so far.

However I have run into issues when it comes to offering specific sizing adjustments for some of our products.

For example: running jackets

• come in two different fitting options (slim fit and regular fit). No extra costs are added. 
• plus we offer sizing adjustments for sleeves (+5cm and -5cm). For sizing adjustments we apply 7 EUR upcharge. 
• sometimes we offer to add custom names for jackets

So far I have been solving this via app called "Avis Product Options". It does the thing and we are able to offer fitting and sizing options from dropdown list. It also offers custom name options with upcharge.

Since we offer custom team designs, we don't stock items and all orders are produced "on demand" once the team shop is closed and all orders are collected for production. This is the part where we run into issues. The only way we can see if customer has selected fitting option or sizing adjustment is by opening each order and extracting data manually (I have attached screenshots for reference). It doesn't show on invoice or packing slip either. 

As far as I understand app is creating additional product to add upcharge for sizing adjustments and custom names. Not sure how fitting options work in this case, but result is that we can't generate reports where we could see which items have been ordered with custom names, sizing and fitting adjustments. Shopify built in reports feature doesn't allow to create reports for specific collections which is essential in our case (as team shops are build as unique collections ). I know there are app that would allow us to generate reports based on collections, but it doesn't solve fitting and sizing adjustments issue. It's possible to see how many times particular sizing adjustment has been ordered, but it's not tied to specific order and product. 

To summarise:

1. Are there any product variant apps that would be better fit for our needs? App that would add information about adjustments directly to product information and not as separate product. 
2. Which app would be most suitable for creating reports by collections AND would offer to extract information allowing us to see which product has been ordered with adjustments?

I hope this makes sense. Let me know if I can explain it any better. 

BR, 

Ed
