If you’re still reconciling client bank statements by hand, or paying for a premium data-capture tool you don’t fully need, you’re leaving hours on the table every single week. Open banking has quietly become the cheapest lever an accounting practice has for cutting admin time, but only if you pick the right tool for your firm’s size and client mix.
This guide breaks down the genuinely low-cost (and several genuinely free) open banking options available to accountants and bookkeepers right now, what they actually cost once you strip away the marketing pages, and which one fits your practice.
What “open banking” actually means for your practice
Open banking is the regulatory framework (PSD2 in the EU, the UK’s Open Banking standard, and equivalent regimes elsewhere) that forces banks to let customers securely share their transaction data with third parties, with consent, through a standardised API. For accountants, this shows up in three practical ways:
- Bank feeds — transactions flow automatically into your accounting software instead of being manually imported from CSV or OFX files.
- Data enrichment — the feed can carry richer transaction references than a card feed, which cuts down on “what was this payment for?” queries to clients.
- Payment initiation — clients (or you, collecting fees) can move money directly from a bank account rather than through a card network, avoiding card fees entirely.
None of this requires an enterprise data contract. The tools below range from completely free to a few pounds or dollars per client per month.

1. Start with what’s already free inside your accounting software
Before paying for anything, check what your existing platform already gives you — because for most firms, this is the entire answer.
Xero. Open banking feeds through Xero’s partnership with Tink are free of charge on every current UK plan, including the entry-level Ignite tier. You do need to re-authenticate the connection roughly every 90 days, which is a regulatory requirement of open banking generally, not a Xero quirk — build a quarterly reminder into your practice workflow so client feeds don’t silently drop. A small number of banks charge Xero a fee for a direct (non-open-banking) feed, and Xero passes that £1+VAT/month cost on per account — worth flagging to clients so they’re not surprised by it.
QuickBooks Online. Open banking connections are free with any QBO subscription. Coverage depends on which UK banks have completed integration, so check the supported-bank list before promising a client a live feed — a handful of accounts (certain offshore or Channel Islands accounts, some card products) still require manual CSV upload.
Hubdoc. If you’re on Xero, Hubdoc is bundled in at no extra cost across every plan tier and will fetch bank and supplier statements automatically, extracting header-level data. It’s the free equivalent of Dext for firms that don’t need line-item extraction — genuinely worth using before you pay for anything else.
The takeaway: if your client roster mostly needs “get the transactions in and reconciled,” you may not need a dedicated open banking product at all. The built-in feed is free and does the job.
2. The genuinely free full-platform option: FreeAgent via NatWest, RBS, Ulster Bank or Mettle
This is the single best-value option hiding in plain sight for practices with sole trader and micro-company clients. FreeAgent normally costs £19–33/month depending on entity type, but it’s given away completely free — full feature set, no time limit — to any business banking with NatWest, Royal Bank of Scotland, Ulster Bank, or Mettle (NatWest’s digital business bank). The client only needs to make one transaction a month through that account to keep it active.
For a practice, this means:
- You can point new sole trader clients toward a Mettle account (free to open) specifically to get FreeAgent at zero cost.
- FreeAgent’s practice dashboard is itself free, letting you manage every client’s ledger from one screen and apply for discounted licences on clients who don’t qualify for the free route.
- Bank feeds are built in and included, with no per-feed fee.
The catch: it’s UK-only, tied to HMRC conventions, and not built for clients with stock, multi-currency needs, or complex group structures. For those, this route doesn’t apply.
3. Document and statement capture: Hubdoc vs Dext
If your clients hand you shoeboxes of receipts alongside their bank data, you’ll want a capture tool layered on top of the bank feed.
Hubdoc (free, Xero only) pulls in statements and receipts and extracts header-level data — supplier, date, total. It’s the right call for lower-volume clients where speed of setup matters more than granular line-item detail, and it costs nothing beyond your existing Xero subscription.
Dext Prepare (paid, works with Xero, QuickBooks, and Sage) goes further — extracting line items, applying supplier-specific rules, and processing bank statement PDFs where a live feed isn’t available. Practice pricing runs from roughly $17.70 per client per month with a 10-client minimum, scaling up for advanced automation and multi-entity handling. That per-client-per-month structure means Dext only earns its keep once a client generates enough document volume that automation actually saves you time — for a client submitting five receipts a month, it’s not worth it; for one submitting hundreds, it usually is.
A sensible rule of thumb: default new clients to Hubdoc, and only move a client to Dext once their document volume makes the subscription pay for itself in reclaimed hours.
4. Recommending bank accounts with bookkeeping built in
For sole trader and micro-business clients who resist any bookkeeping discipline at all, an account that does the categorisation itself — using the same open banking rails — can solve more problems than a separate software subscription ever will.
- Tide bundles a business account with invoicing and bookkeeping tools; a VAT-registered sole trader on the full bundle lands around £33/month all-in, but the base account tier is far cheaper if the client doesn’t need the add-ons.
- Countingup has no permanent free tier (just a three-month trial), after which the fee is set automatically by average monthly deposits — £3/month under £750, rising to £18/month above £7,500 — plus 30p per transfer in and out. It’s simple and predictable at low deposit volumes, but the transfer fees add up fast for an active trading account.
- Coconut takes a different approach: it doesn’t replace the bank account, it reads an existing one via open banking and layers bookkeeping and MTD filing on top, at £99.99–159.99 a year depending on plan. It’s built specifically around accountant-led workflows, which makes it a stronger fit than the bank-bundled apps if you want to stay in the loop on a client’s numbers rather than have them self-serve inside a banking app.
None of these replace your practice management software — they’re a way to get a disengaged client’s raw data clean and current without a fight, so pick based on how hands-on the client wants to be, not on price alone.
5. Cutting payment costs with pay-by-bank
Open banking isn’t only about receiving data — it also lets you move money without a card network in the middle. GoCardless Instant Bank Pay and similar pay-by-bank tools let clients pay one-off invoices (including your own fee notes) directly from their bank account, settling faster and without the roughly 1.5–3% card processing fee. For a practice invoicing clients monthly, or collecting one-off fees for tax returns and ad hoc advisory work, switching from card payment links to pay-by-bank is one of the few genuinely free wins available — you pay a transaction fee, but it’s typically a fraction of card interchange, and there’s no card-present hardware or PCI compliance burden to worry about.
If you use FreeAgent, this arrives already integrated through its existing GoCardless partnership; Xero and QuickBooks both support GoCardless as a connected payment method too.
6. Advanced option: building your own tools on raw open banking APIs
Larger practices building a proprietary client dashboard, an automated reconciliation tool, or a bespoke credit-control system will eventually outgrow off-the-shelf software and need direct API access. A few notes if you’re evaluating this route:
- The old free tier is gone. GoCardless Bank Account Data (formerly Nordigen), long the go-to free option for developers, has closed new signups and is being wound down — if a guide or forum post still points you there, it’s out of date.
- Enable Banking is currently the closest self-serve, low-cost European replacement, offering free “restricted production” access for accounts you link yourself, with paid tiers for real client volume.
- TrueLayer, Tink, and Yapily all offer developer-friendly APIs with usable sandboxes and startup-friendly pricing, though none publish flat public price lists — expect to talk to sales once you’re past a handful of live connections.
- Plaid is the strongest option if any of your clients are US-based, with broad North American bank coverage, though it’s less dominant in UK/EU open banking specifically.
This route only makes sense if you have (or can hire) development capacity. For the vast majority of practices, the off-the-shelf tools above will get you 90% of the benefit for a fraction of the effort.
How to choose: a decision framework
- Solo bookkeeper or small practice, mostly sole traders? Start with FreeAgent via Mettle/NatWest for eligible clients, and Hubdoc for everyone else already on Xero. You may spend nothing beyond your existing Xero or QuickBooks subscription.
- Growing practice with clients across account types? Keep bank feeds native to Xero/QuickBooks (free), add Dext once a client’s document volume justifies the per-client fee, and use GoCardless pay-by-bank for fee collection.
- Practice with disengaged sole trader clients who won’t do their own bookkeeping? Recommend Coconut or Tide as the client-facing layer, so the data arrives clean without you chasing them.
- Firm building proprietary tooling? Budget for Enable Banking or TrueLayer/Tink at the sandbox stage, and get a real quote before committing — don’t assume free-tier pricing you’ve seen referenced elsewhere still applies.
Common mistakes to avoid
- Assuming a bank feed, once connected, stays connected. Open banking consent typically expires around every 90 days. Build reconnection into a recurring practice checklist, not something you discover when a client’s feed goes stale mid-quarter.
- Paying for Dext-level automation on low-volume clients. The per-client-per-month model means you’re paying whether or not the client generates enough documents to make it worthwhile. Segment clients by volume before assigning a paid tool.
- Ignoring pass-through bank fees. A handful of UK banks charge providers like Xero for direct feeds, and that cost is passed to the subscriber. It’s a small amount, but it’s worth disclosing to clients rather than letting it show up as a surprise line item.
- Chasing a “free API” that’s no longer free. The open banking developer landscape has consolidated fast; several previously-free options (most notably the old Nordigen/GoCardless Bank Account Data free tier) have closed to new users. Always verify current terms on the provider’s own pricing page before building anything around them.
FAQs
Q1. What is the cheapest open banking solution for accountants?
For most practices, the cheapest option is one you already have: bank feeds inside Xero and QuickBooks Online are included free with any subscription tier, with no separate open banking charge. For sole trader clients, FreeAgent is free indefinitely if they bank with NatWest, RBS, Ulster Bank, or Mettle, making it the cheapest full-platform route available in the UK.
Q2. Is open banking free for accountants to use?
The underlying open banking connection is free in almost every mainstream accounting platform — Xero, QuickBooks Online, and FreeAgent all include bank feeds at no extra charge. Costs only appear if you add a paid document-capture layer like Dext, choose a bank-bundled bookkeeping app like Tide or Countingup, or build custom tools on a commercial API such as TrueLayer or Enable Banking.
Q3. What’s the difference between Hubdoc and Dext for accountants?
Hubdoc is free with every Xero subscription and captures header-level data (supplier, date, total) from bank statements and receipts. Dext Prepare is a paid, per-client subscription that extracts full line-item detail and applies supplier-specific rules, making it worth the cost only once a client’s document volume is high enough that the automation saves more time than the subscription costs.
The Final Thoughts
For most practices, the lowest-cost open banking stack isn’t a new tool at all, it’s the bank feed already included in Xero or QuickBooks, paired with Hubdoc for document capture and FreeAgent’s free NatWest/Mettle route for eligible sole trader clients. Layer in Dext only where document volume justifies it, and switch fee collection to pay-by-bank to cut card costs. Reach for a raw API provider only once you have a specific, repeatable workflow that off-the-shelf software genuinely can’t handle.
