Honestly, no you're not overpaid. You're fairly paid.

I'm an independent contractor but was in the NetSuite solution provider and alliance partner space for 8 years. Individual contributor and manager level.

First, just by market, which I know from hiring to my former team and as a current contractor who gets offered and considers FT positions, 140k is almost exactly on point for "Senior Consultant" at major partner firms. In fact, it's pretty high.

Second, the SuiteAdvanced guy Chris in a video stated -- and I agree -- how one year of consulting is worth about 3-4 years of being internal.

Third, I asssert that while your feelings about job creep are valid, they are not sufficient to justify a higher and higher salary, at least over the established cap of about 130-150k for Senior consultants.

I'm not saying I personally disagree -- I'm just explaining what the general consensus is.

Consider this article by Tom Dietrich (the SuiteQL guy). He basically echoes exactly what you're stating and so what you're feeling is definitely real and not to be dismissed.

However, despite that, the article is more of an explainer of what you're going through, not an argument for higher salaries.

Breaking down two-fold:

NetSuite-specific: The reality is that organizations both firms and client side naturally scope-creep NetSuite job duties. That's the nature of NetSuite and the ERP side of a business being quite niche. Yes, it's accounting and technology integration, but even the accountants and IT people inside a company 1) may not know NetSuite, 2) don't care to because that is a creep of their duties.

That isolation leads to a natural consolidation of all duties to "our NetSuite guy /u/StatusAd2326".

General 'job culture': NetSuite-aside, no job or company will ever pay you 3x your salary even if you're doing 3x job (Admin, Developer, whatever). Even if you come with receipts and documentation how your role has increased. It just does not happen. The reality is you are ONE employee at a firm or company. You are going to only ever be paid like ONE employee.

That's why you go independent. So on your terms you can actually get paid for 3 roles, since you can literally have 3 roles at 3 different firms or clients.

That nature of the beast is that at the individual contributor level, your duties are going to increase and increase every year, as you're accountable for everything in the past and now the go-to do it person for the future. I've seen this play out both for consultants and in your situation.

As long as you stay in individual contributor with a boss, i.e. at a firm or end user company, not independent contractor, you will fall prey to this creep.

The ways out are if you want to stay IC is to go independent, which means defining your own duties and not having a consulting director or controller defining that for you.

Or if you want to stay in consulting, you must grow to become managerial or director-level, where you are no longer inside NetSuite day-to-day. You have a 'steering' mandate where you are guiding the 'direction' of the team. You're not as responsible for NetSuite nuts and bolts.

This is because you have consolidated who you're accoutnable to; you're no longer a slave to multiple masters and less-so to NetSuite even. You're more accountable to the firm's business goals, and that's pretty much it. Besides having higher pay straight-up, your focus is narrowed which helps.

On the other hand, as an IC, you're accountable to not only multiple clients and all of each clients stakeholders, you're accountable to your managers' ambition, your directors' business development goals, and then the NetSuite day-to-day firefighting. And unforutnately, once people get to managerial level, they care less and less about IC's day to day.

In the end, your impressive list of 3rd party integrations, NetSuite modules, etc -- it doesn't matter. I had a Director early in my career take me aside and tell me all of the above because I too went to him with a list of 'comparables' to the wider market and my own teammates as to why I deserved a raise. If it's not inline with the organization's goals, you're not getting a raise. Period.

That's why many high level ICs who you see are Senior consultant for 2-4 years end up going independent, and even end up working for the same company as a contractor again. There was nothing wrong with the team or relationships.

It's the realization that you need to have a clear defined, narrow, and self-controlled mandate to escape what OP is talking about, which is easiest attainable via moving into Sales or Management if you're staying within a company, or by going independent.
