- Journal entries, reconciliations and the monthly close
- Invoices, reports and approvals that run themselves
- Built inside the tools you already pay for
- Hours and error rate measured before and after
Formation, EIN, ITIN through an IRS-authorized Certifying Acceptance Agent, the company and personal returns, and the bookkeeping underneath them.

- Dashboards built around decisions, not every metric
- Refreshed on their own, not rebuilt on Mondays

Your gateway to the U.S. market.
Setting up in the United States from abroad is mostly a sequencing problem: the entity, the EIN, the ITIN, the bank account and the filings each depend on the one before. We manage the whole chain so nothing stalls halfway.
Where do you want to start?
Each one has its own guide and its own questionnaire, so you can price your case before you speak to anybody. Most people arrive for one and end up needing two.
Form the company
LLC or Corporation, which state, how to open a bank account with or without travelling, and the EIN.

Tell us where you are and we will point you to the one you need, or to the two.
Tell us your caseFive steps, in this order, or it stalls.
Most of the trouble we are called in to fix comes from doing these out of order — an entity with no EIN, or a bank application with no ITIN behind it.
Entity
LLC formation in the state that fits your situation, with the operating agreement and registered agent in place.
EIN
Your federal tax ID, obtained for the company — including where the owners are non-residents without an SSN.
ITIN
Your individual taxpayer number, certified by us directly as an IRS-authorized Certifying Acceptance Agent.
Banking
Preparing the documentation and company profile U.S. institutions will ask you for.
Filing
Bookkeeping through the year, then the federal and state returns the entity is obliged to file.
Your passport never leaves your hands.
The standard route to an ITIN means mailing your original passport to the IRS and waiting for it to come back. For anyone who travels, that is not a small thing.
Big Skill Solutions is a Certifying Acceptance Agent authorised by the IRS. We verify your identity documents ourselves and certify the application, so the originals stay with you.
- ✓Owners, spouses and dependentsITIN applications for non-resident owners and for the family members who need one.
- ✓Form W-7 prepared and submittedTogether with the supporting tax return where one is required.
- ✓Certification handled in-houseNo mailing originals, no waiting on their return before you can travel.
- ✓RenewalsAn ITIN that has gone unused can expire. We handle renewal before it affects a filing.
Accounting and U.S. tax filing.
Registering the company is the easy part. Staying compliant is the part that catches people out.
If any of these is you, this is the service.
- Selling to U.S. customers who want a U.S. supplier
- Needing a U.S. entity to access payment processors
- Without an SSN, and unsure what that changes
- An LLC formed but no EIN or ITIN behind it
- Filings missed, or unsure which ones apply
- Bookkeeping that has drifted from reality
Tell us where you are in the sequence.
Starting from zero, or stuck halfway — either way the first conversation is free and we will tell you exactly what is missing.
