Comparison facts checked 3 November 2026
A Sodium HQ alternative for practices that only need to own the filing risk.
Sodium HQ is built as a broader practice-management platform. FilingKeeper is intentionally smaller in scope: it gives a UK accounting or bookkeeping practice one place to see statutory deadline risk, clear document blockers, chase clients and keep proof after filing.
This is an honest fit comparison, not a claim that one product suits every practice. Sodium HQ facts below link to its own published pages and are dated so they can be checked again before a decision.
The trade-off: full-suite migration versus a focused workflow.
A full practice-management switch can mean deciding what happens to proposals, engagement letters, CRM records, billing, time and work in progress at the same time as you are trying to make filing work safer. That can be the right investment for a practice that needs all of those workflows. It is more change than a practice needs when the immediate problem is a fragile spreadsheet, unchased records and no calm view of statutory dates.
FilingKeeper does not ask you to replace the software you use to keep books or submit returns. Add clients, record their year-end and obligations, and see the dates the statutes set. The practice still reviews and files; FilingKeeper makes the risk and the evidence visible.
Designed around UK statutory deadlines.
The core FilingKeeper workflow starts with the deadlines a UK practice has to keep straight: Companies House accounts and confirmation statements; VAT, Corporation Tax and CT600; Self Assessment; MTD for Income Tax; and PAYE. The product calculates them from the client's own dates and registrations, rather than treating a deadline as a generic task date.
That narrowness is deliberate. It keeps the daily question simple: what is blocked, overdue or due next, who needs to act, and is the proof attached once the practice has filed? It is a better fit when compliance coordination is the job you want to improve without buying a whole operating system for the firm.
One key difference: risk and proof stay with the filing.
FilingKeeper's Risk Center ranks open filings by what needs attention: blocked work, overdue work, work due this week and what is next. A team can record why something is blocked, request the missing document through a loginless upload link, and keep the receipt or confirmation beside the filing after the practice submits it.
That is different from promising a broad practice-management migration in a few clicks. A practice can try the focused deadline workflow with a small set of live clients and keep its existing books, filing software and broader internal processes in place.
What Sodium HQ appears to do well.
Sodium HQ is worth considering when the practice wants a single wider platform. Its public materials cover document requests and HMRC agent authorisations, and its pricing is structured around client count. Its published pricing also showed a free option at the smallest client count and up to 25 users on paid plans when checked.
The wider scope can be valuable for a practice actively looking to consolidate processes. Before choosing either product, test the workflows that matter to your firm and confirm current plan terms directly with Sodium HQ. We do not claim a feature-for-feature result where its public documentation does not let us verify one.

Moving your data: start with the work you need to see.
Trying FilingKeeper should not mean rebuilding a full practice system. Start with a handful of clients, their accounting reference dates, statutory registrations and any current filing status. That produces a live filing schedule you can check against your existing records before rolling out more widely.
CSV import and a fuller switching guide are planned separately. Until those routes exist, this page makes no claim that FilingKeeper imports data from Sodium HQ automatically. The important question is whether the team can see the real deadline picture and its blockers without losing the systems it already relies on.
Questions about choosing a Sodium HQ alternative.
Not for every practice. Sodium HQ is a wider practice-management product. FilingKeeper is deliberately narrower: it tracks statutory deadlines, shows filing risk, chases missing documents and keeps filing proof. It suits a practice that does not want to move CRM, engagement, billing or time-and-WIP processes.
The published price points in the table are not like-for-like products. On the checked figures, FilingKeeper Business is £149 per month with unlimited clients, while Sodium HQ Standard reaches £149 at 500 clients. Check Sodium HQ's own pricing calculator before making a buying decision because its plans and VAT treatment can change.
Sodium HQ's published pricing showed a free option for up to five clients when this comparison was checked. See the linked Sodium HQ pricing page for the current eligibility and plan terms.
Yes. A practice can create a document request with a loginless upload link and optional scheduled chasers. The client does not receive a statutory-filing reminder; the request is for the missing document that is blocking work.
No. FilingKeeper does not claim to provide HMRC 64-8 authorisations or AML workflow. Those are examples of wider practice-management needs to assess separately.
No. Start by adding a few clients and their year-ends, registrations and applicable obligations. FilingKeeper works alongside the accounting and filing software you already use; it does not file to HMRC or Companies House for you.
