White-label capacity for US accounting firms.
Bookkeeping, AP/AR and month-end close for your US clients, prepared inside your own systems under your file-naming conventions. Your CPA reviews and files — we never contact your client.
A US client that crosses an economic nexus threshold doesn't file once — each state sets its own rate, its own portal and its own cadence, commonly triggered around $100,000 in sales or 200 transactions in that state alone. Whoever preps the books has to keep every state straight before it reaches your review.
QuickBooks Online
QuickBooks Online dominates US SMB accounting, and multi-state sales tax usually means bolting on Avalara or TaxJar rather than relying on native tax tables.
The deadlines we track against your ledger.

Last reviewed against the source . These are the standard dates. Extensions through a registered agent, a non-calendar year end, and volume-based filing frequencies all shift them — confirm your own dates with IRS. This is general information, not tax advice.
Firms use us for the preparation layer: workpapers, schedules, reconciliations, and the runs behind the 1120, 1120-S and 1065 packages a partner has to sign before the deadline. We work inside your systems under your naming conventions and hand back review-ready files — never a client-facing role.
What stays with your registered agent
Your CPA signs and files under their own PTIN and EFIN. We prepare to filing-ready state; we never hold ourselves out as a preparer of record and never file under our own name.
The same file discipline, already proven directly.
Salt has no white-label clients in United Statesyet. What's below is the direct-delivery work the process is built on — the same reconciliation and handoff standard a white-label file goes through.
US restaurant, catering and outdoor events LLC
A migration checked line by line, not trusted to the tool
A US LLC moved from Xero to QuickBooks without disrupting operations — because every opening balance was verified rather than assumed.
Small corporations and LLCs across the US and UK
Books built to be handed straight to someone else's CPA
Several small businesses needed reliable QuickBooks bookkeeping organised well enough to pass cleanly to their own accountant for annual filing and audit.
