We run an EU-based Shopify store selling physical products mainly to U.S./Canada customers, and we’re getting close to U.S. economic nexus thresholds.

I understand Shopify can help track/calculate tax, but I don’t want to manually deal with 50 states, registrations, filings, zero returns, remittance, notices, etc.

For other EU/non-U.S. founders who scaled into North America:

• Which sales tax service actually handled everything properly?
• Any hidden issues with foreign entities, U.S. bank accounts, Shopify Tax, or Streamlined Sales Tax?
• Did you set up a U.S. entity for payments/exit reasons, or just keep operating through your home-country company?

Looking for real experience from people who have already gone through this.

I'm might at some point be obligated to start paying sales tax in multiple states.

​

Have anyone built their business up to that level? Our margins are tight and I'm not thrilled about this.

​

1. How much adding sales tax to the price at the checkout affects conversions? As mentioned, I don't think I can just keep current prices and pay the 8% from that myself.

​

2. How complicated is the reporting and filing? Do I need company for that or do it myself from Shopify? If outsource, any recommendations on the company which would be affordable and efficient?

What's the best and safest (read: officially accepted) way to automatically publish and optionally edit/manage the ads?

I have my semi-auto ad pipeline, but I'm hesitant to connect via graph API due to my own and others experiences with account bans which might (or might not) be related to automating accounts.

I can make the ads in any format (ie. spreadsheets, txt files or use API directly), but would need more efficient way to mass publish ads.

How are big agencies doing this when publishing 1000+ ads weekly?

I run an ecommerce brand which I think has real potential.

It’s already selling (100k+ this year), no real competition, reviews are genuinely strong, customers seem very happy, and repeat purchases / LTV looks good. The problem is that I’m not a professional media buyer and I don’t have enough capital to really push this to the next level.

So I’m wondering if there are legit companies who partner with brands like this?

Could be either:

someone who only provides capital for ads/growth

or a real growth partner who also operates the ads/funnel and takes profit share, revenue share, equity, or some similar deal (preferred since my paid ad experience is limited)

I’m not really looking for a normal agency where I pay a big retainer and still carry all the risk myself.

Has anyone here done something like this, or know companies/people who are actually legit in this space? Also interested in any red flags or deal structures I should avoid.

Also, not outing my business here so please do not ask.

I've been trying to find some more permanent account structure which I could keep and have system for expanding, but there just don't seem to have any real consensus and/or there's issues with all advices I've got - and typically those advice most likely comes from people who never have actually managed profitable brands with decent spending and they are just parroting the consensus without real understanding.

I've simplified to this structure now:

- A+ Campaign, 1 adset, about 8 ads there, single ad (with 10 statics) getting 98% of the spending (750/d)

- Retargeting (50/d)

##

I've done ton of different testing on how to test and scale new creatives or expand current winner, but none have really sticked - and quite often it seems to actually decrease the overall account performance (not really sure why, but it decreases the current winner even I don't touch the main campaign).

I've tested in ABO, inside the main A+ in different ad sets, I've made new A+ for testing, I've duplicated the old one, I've created TOF/MIF/BOF funnel - but as said, none I've found truly working and something I could keep as a system. I've conducted deep research with top AI models to find out the answer, I've prompted different ways, researched the actual algos as well as discussions - but still out of luck to find actually working setup.

Question 1

Now I have 9 new ads ready (each having 3-5 creative variants) around the current winner - some are just variants of the same angle, some are targeting slightly different angles/needs, but still same base audience, just slightly different segment and purpose.

How do I introduce, test and scale these new ads? And not just this time, but in the future too - I'd like to find a system which can be repeated and not just something I randomly test and hope it sticks.

Big issue with most setups is these two:

1. If I find new winner(s) from those 9 ads - if I add any to the current adset with the spend hog, these new winners won't get any spend anyway. Does this matter? Does meta know how to shift from the old spender to new when it starts to die? Will these get spending if I just push the budget up? Should I switch the old ad off at some point?

2. If I create new A+ or duplicate the old one for these new winners, this affect the performance of old A+ too (at least this is my experience) - not sure because both are competing with each other or what is the reason. Also, this doesn't seem like lasting structure, but something that would create just big mess once new winners keep building new campaigns.

##

Question 2

I also have new product versions coming. It's different style, but mostly same product and audience, partly also different segments.

How do I test and scale these since these are different from the current winner? Do big spenders scale different product versions (for example poster with dog vs poster with funny text about dogs) inside the same campaign/adset or would these go to different campaigns? What's the reasoning here? Issue with ton of campaigns for different products is that it seems to decrease the overall performance of the account (at least with my limited experience), but also adding new product versions to single A+/adset have the issue of not getting any spend.

##

This is basically the open questions what I've never found real answers since I started with paid ads and even I've researched and learned a LOT in the past 6+ months, these questions never get truly answered anywhere - and almost daily people keep asking the same questions here too.

I know this is a lot, but truly hope that someone with actual, real experience could take some time to address how they are handling their big accounts properly.
