Special situations
Switching from Crunch
Founders running a UK-registered company on Crunch who add a US entity need a second, separate set of books, not a UK file stretched to fit. Finbryn sets up the US entity on QuickBooks Online or Xero under US GAAP, tracks intercompany balances against the UK side, and flags Form 5472 exposure early for foreign-owned structures.

Crunch is a UK-focused bookkeeping and accountancy platform built for sole traders and small limited companies: fixed monthly fees, a UK chart of accounts, Self Assessment and Corporation Tax filing baked into the plan, ACCA and CTA-qualified staff reviewing the numbers. It does one thing well, UK compliance for a UK entity, and it was never built to carry a second entity incorporated in Delaware, Wyoming or anywhere else in the US.
That gap shows up the moment a UK founder incorporates a US subsidiary, or a US company gets funded by UK shareholders. The two entities need separate books on separate standards: US GAAP and IRS conventions on one side, UK GAAP/FRS 102 and HMRC conventions on the other. Forcing one chart of accounts across both usually means the US side ends up as an afterthought bolted onto a UK-shaped file, with US-specific categories, sales tax, and 1099 tracking missing entirely.
Finbryn's role here is narrow and specific: stand up the US entity's own QuickBooks Online or Xero file, independent of whatever Crunch maintains in the UK, and get the intercompany relationship between the two entities right from day one. That usually means a loan or capital contribution from the UK parent to the US subsidiary, or management charges flowing one direction or the other, both of which need to be booked, tracked, and reconciled on both sides so neither entity's balance sheet quietly overstates what the group actually owns.
Where the US entity is majority or partly owned by a non-US person or entity, foreign ownership brings Form 5472 into the picture. This isn't optional paperwork: a US corporation or disregarded single-member LLC that is 25% or more foreign-owned, or that has a reportable transaction with a foreign related party, has to file Form 5472 attached to a pro forma Form 1120, and the penalty for getting it wrong starts at $25,000 per related party with no statutory ceiling on top of that. We flag this in the first week of onboarding, not after the first year-end.
Once the file is set up and any UK-US intercompany balance is agreed with both sides, Finbryn runs monthly bookkeeping for the US entity on its own schedule. Crunch keeps doing what it does in the UK. The only thread connecting the two files is the intercompany balance itself, reconciled each period so a lender, investor, or the credentialed signer preparing either return is working from numbers that actually tie out.
What is included
The engagement starts with a new QuickBooks Online or Xero file for the US entity, set up under US GAAP conventions rather than adapted from a UK chart of accounts. We review the UK-side Crunch records only far enough to identify any balance the two entities owe each other: a founder loan from the UK parent, a management fee, a cost-sharing arrangement, or capital contributed at formation. That balance gets its own intercompany account on both sides, so it can be reconciled every period instead of drifting apart. From there, ongoing monthly bookkeeping for the US entity runs independently: bank and card reconciliation, categorization against a US-appropriate chart of accounts, and monthly P&L and balance sheet reporting. Nothing about the UK entity's Crunch subscription or reporting changes; this work sits entirely on the US side of the structure.
How the process works
We start with a short intake covering the US entity's formation documents, EIN, bank accounts, and the nature of the relationship to the UK parent or shareholders, funding, services, shared costs, or some combination. In parallel we pull whatever export or summary Crunch can provide for the UK side, not to migrate it, but to confirm the intercompany figures agree with what the UK books show. Once the US file is built and the opening intercompany balance is agreed in writing with you, monthly bookkeeping begins on Finbryn's standard schedule. Where Form 5472 applies, we build the underlying transaction log for that filing into the monthly close from month one, rather than trying to reconstruct a year of intercompany activity the following March.
Common problems we fix
The most common issue is a US entity with no distinct chart of accounts at all, transactions parked in a generic 'intercompany' or 'suspense' bucket because nobody set up US-specific categories at formation. The second is an intercompany balance that was tracked casually, a spreadsheet, an email thread, a verbal understanding, with no consistent figure on either side. The third is missed Form 5472 exposure: founders who know Form 1120 is due but don't realize a foreign-owned entity with reportable transactions needs Form 5472 attached, and that failing to file it carries its own $25,000 penalty separate from any late-filing penalty on the 1120 itself. We catch all three during the initial setup review, before they compound into a bigger cleanup.
Software and integrations
The US entity's books run in QuickBooks Online or Xero, whichever fits your existing US banking and payment stack better, we do not require one over the other. We connect US bank and card feeds directly rather than relying on manual statement imports where the bank supports it. For entities also running payroll on the US side, we work alongside Gusto, ADP, Rippling, or Deel rather than duplicating payroll data entry inside the accounting file. Crunch itself stays untouched on the UK side; we do not integrate with or pull live data from it, since the two entities' books are deliberately kept separate rather than consolidated into one system.
Who this is for
This service fits a UK-registered company, sole trader or limited company on Crunch, that has incorporated or is incorporating a US entity: a Delaware C-corp to raise US venture funding, a US LLC to hold US operations or a US bank account, or a US subsidiary to employ American staff or contract with American customers. It also fits the reverse structure: a US company with UK-resident founders or investors who need the US side handled to US standards while UK compliance stays with Crunch. It does not fit a business trying to replace Crunch entirely for its UK entity; that is a UK bookkeeping engagement, not this one.
Controls and review
Every month's close for the US entity, including the intercompany reconciliation, is reviewed by a senior reviewer before it reaches you. You keep direct access to the QuickBooks Online or Xero file at every stage; nothing about the US books lives somewhere you cannot see it yourself. Where Form 5472 or the underlying Form 1120 needs a signature, that return is prepared by our team and filed by a credentialed signer, an enrolled agent or CPA partner, never by Finbryn directly. The engagement letter sets out exactly which entity, which accounts, and which filings are in scope before work begins.
What it costs
Pricing for this engagement follows Finbryn's published US rate card rather than a bespoke quote invented for a UK-to-US structure. Setting up the new US file and the initial intercompany reconciliation is typically scoped as a one-time project fee, sized to the complexity of the intercompany relationship and how many periods need to be reconstructed. Ongoing monthly bookkeeping for the US entity then runs at the standard monthly tier that matches its transaction volume. Form 5472 and pro forma Form 1120 preparation support is a separate add-on, priced on the current rate card, and confirmed in writing before the first filing deadline arrives.

Common problems we fix
The problem
How we fix it
- US transactions get dumped into a generic suspense or intercompany bucket with no real chart of accountsWe build a US-specific chart of accounts at setup so transactions land in categories a US preparer can actually use.
- The UK-US intercompany balance exists only as a spreadsheet or a verbal understandingWe agree and book a formal opening balance in writing, then reconcile it every month going forward.
- A foreign-owned US entity misses Form 5472 entirely because the founder only tracked the Form 1120 deadlineWe screen for the 25%-foreign-owned threshold and reportable transactions during onboarding, before the first filing deadline.
- Management charges between the UK and US entities are recorded inconsistently on each sideWe standardize the intercompany account structure so both entities show the same figure for the same charge.
- The US bank account has months of unreconciled activity because no one owned US bookkeeping before incorporation settledWe scope a short catch-up from the account-opening date before ongoing monthly bookkeeping starts.

Switching from Crunch
Glossary
- Intercompany balance

- Pro forma Form 1120
- A simplified version of the corporate tax return that a foreign-owned disregarded LLC attaches to its Form 5472 filing, since it otherwise files no income tax return of its own.
- Reportable transaction
- Under Form 5472 rules, any transaction with monetary consideration between the reporting entity and a foreign related party during the tax year.
- US GAAP
- Generally Accepted Accounting Principles used for US financial reporting, distinct from the UK's FRS 102 framework that Crunch's UK clients report under.
Questions
Frequently asked questions: Switching from Crunch
We still use Crunch for our UK company. Can Finbryn just handle the new US entity?
Yes. We set up and run the US entity's books as a completely separate file. The only connection to what Crunch maintains in the UK is the intercompany balance between the two entities, which we track and reconcile on the US side each month.
Do the UK and US books need to use the same accounting standard?
No, and they shouldn't. The UK entity stays on whatever standard Crunch applies there. The US entity runs on US GAAP and IRS conventions. We reconcile the intercompany balance connecting them rather than forcing one chart of accounts across both.
Does a new US entity owned from the UK automatically need to file Form 5472?
Only if a foreign person or entity holds at least 25% of the voting power or value, or the entity had a reportable transaction with a foreign related party. Most UK-parent structures meet that threshold, so we check it during onboarding rather than assuming either way.
What happens if we already missed a Form 5472 deadline before finding Finbryn?
We flag it immediately and help you prepare the missing filing for your credentialed signer to submit along with a reasonable-cause statement where one applies. The penalty exposure is real, so the priority is getting the filing in, not waiting for a better time.
Can you match the reporting format Crunch already produces for the UK entity?
We don't replicate Crunch's UK-specific report layout, since the US entity's reporting follows US GAAP conventions instead. What we do match is your reporting cadence, so both entities' numbers land on your desk around the same time each month if that matters to you.
Who actually reviews the intercompany numbers before we see them?
A senior reviewer reviews every period's close, including the intercompany reconciliation, before it reaches you. You keep direct access to the QuickBooks Online or Xero file throughout.
Do you file the Form 5472 or the Form 1120 yourselves?
No. We prepare the return and the supporting transaction records; filing itself goes through a credentialed signer, an enrolled agent or CPA partner, consistent with how every tax filing works across Finbryn's services.
What if the US entity's books are already a mess by the time we call you?
We scope a short catch-up covering the account-opening date to today before starting ongoing monthly bookkeeping, so the intercompany balance and the US chart of accounts both start from a reconciled base rather than compounding an existing gap.
We still use Crunch for our UK company. Can you just handle the US side?
Yes. We set up and run the US books separately and track any balances the two entities owe each other.
Do the UK and US books need to match?
They stay on their own standards, US GAAP here and UK reporting there, with intercompany balances reconciled between the two.
What is included in switching from Crunch?
Switching from Crunch covers a new QuickBooks Online or Xero file set up for the US entity and uK-side records reviewed for any intercompany balances that need to carry over. The exact scope is agreed and set out in writing before work starts, so you know precisely what is and is not covered before the first deliverable arrives.
How is switching from Crunch priced?
Pricing for switching from Crunch depends on your transaction volume, the software you use, and how much cleanup is needed before ongoing work starts. Current ranges are published on the pricing page, and your exact fee is confirmed in writing before anything begins.
