Zoho CRM and Zoho Books Integration for UK Businesses: What It Actually Delivers

Two Systems, One Customer Record
Copying a quote out of your CRM to raise an invoice is the kind of small, repeated task that produces real errors: a mistyped line item, a wrong VAT rate, an invoice for the wrong amount. The Zoho CRM and Zoho Books integration exists to remove that step, and it largely succeeds.
Before the mechanics, though, one thing needs correcting, because it is the most time-sensitive fact in this subject and almost every guide still has it wrong.
MTD for Income Tax Is Live, Not Coming
Making Tax Digital for Income Tax has applied since 6 April 2026 to sole traders and landlords with qualifying income above £50,000. It is not forthcoming, not incoming, and not something to plan for.
The thresholds, in full:
- £50,000 qualifying income — since 6 April 2026
- £30,000 — from April 2027
- £20,000 — from April 2028
Note that the test is qualifying income, which is gross turnover rather than profit, and it is assessed on an earlier tax year — so a business under £50,000 of profit can still be in scope.
If you are in scope, your quarterly update deadlines are 7 August, 7 November, 7 February and 7 May, with a Final Declaration by 31 January. The second of those falls in early November, which makes this a this-fortnight problem rather than a next-year one for anyone who has not yet registered.
Where Zoho Books Actually Stands
Guides written before April tend to say Zoho is “working towards” compatibility. It is not. Zoho Books is HMRC-recognised for Making Tax Digital for Income Tax, and it supports digital record keeping, quarterly updates and the final tax return.
Better than that, and genuinely unusual: Zoho’s UK pricing page offers MTD for Income Tax on the free plan, describing sole traders and landlords as able to stay compliant all year on it, including sending quarterly updates and submitting the final return. MTD for VAT filing is on the free plan too.
The Catch Worth Knowing
Zoho’s own announcement says the MTD for Income Tax feature is available on request rather than switched on by default — you contact Zoho’s UK support to enable it.
That announcement also frames participation as voluntary and references registering for HMRC’s testing phase, which reads as pre-April-2026 wording that has not been refreshed. The mandate itself commenced on 6 April 2026, so if you are in scope, confirm the current submission route with Zoho support directly rather than relying on the published page. Do that before a deadline rather than during one.
How the Integration Works
Both products sit inside Zoho’s own ecosystem, so this is a native integration rather than something stitched together with Zapier or Make. That generally means it is more granular and less likely to break when either product updates.
Quotes to Invoices
The most tangible win. In Zoho CRM you create a quote against a deal; when the prospect accepts, it converts into a Zoho Books invoice without rekeying line items or re-checking VAT rates.
This matters more than it sounds. Rekeying between systems is among the commonest sources of invoicing error in small businesses, and the gap between “deal won” and “invoice sent” is cash flow.
Payment Status Back in the CRM
Once an invoice exists in Books, its status syncs back to the CRM record. Anyone looking at a customer can see whether an invoice is outstanding, overdue or paid without a Books login.
For a one-person business that is simply one view instead of two. For a small team it prevents a salesperson pitching a new deal to someone three months in arrears.
Contact Data in Both Directions
Contact records sync both ways, so a number updated in the CRM reaches the accounts system and a customer created during invoicing appears in the pipeline. It removes the slow divergence that otherwise builds between two address books.
Worth spending time on the field mapping at setup, particularly around product catalogues and VAT codes, rather than discovering a mismatch on a live invoice.
Zoho CRM and Zoho Books Integration: What Plans You Need
On the CRM Side
The Zoho Books integration requires Standard, £12 per user per month on annual billing, or £16 monthly. It is not on Zoho CRM’s free tier, which is a three-user plan otherwise worth having.
Standard is a reasonable place to land anyway, because it is also where multiple sales pipelines start — a point covered in our Zoho CRM pricing guide, where the same capability is commonly misreported as an Enterprise feature at £35.
On the Books Side
Zoho Books has six UK tiers, not the four usually listed, priced per organisation rather than per user:
| Plan | Annual (per month) | Monthly |
|---|---|---|
| Free | £0 | £0 |
| Standard | £10 | £12 |
| Professional | £20 | £24 |
| Premium | £25 | £30 |
| Elite | £85 | £99 |
| Ultimate | £165 | £199 |
All exclude local taxes. Because Books is priced per organisation, adding users to your CRM does not multiply your accounting bill.
What the Free Books Plan Actually Includes
Usually waved away as needing verification, so here are the real limits from Zoho’s UK pricing page:
- 1 user plus 1 accountant
- 1,000 invoices a year
- 1,000 expenses a year
- 3 projects
- 50 receipt autoscans a month
- 5 scheduled reports
- No add-ons except CT600 and Final Accounts
- MTD for VAT filing and MTD for Income Tax, including quarterly updates and the final return
You will also read that the free plan carries a turnover limit of around £35,000. Zoho’s UK pricing page states no turnover limit. If that constraint applies to you it is not published where you buy, so ask before you rely on either version.
For a sole trader invoicing modestly, a free accounts package that files both MTD regimes is a genuinely strong position. The binding limit is the single user.
VAT Handling
For VAT-registered businesses, Books lets you set VAT rates, assign them to products and services, and generate returns, and it is HMRC-recognised for MTD for VAT — which already applies to all VAT-registered businesses regardless of turnover.
When quotes convert to invoices, VAT codes carry across from your product catalogue provided they were set up correctly in Books first. Configure that before you go live, especially with mixed rates across product lines, and test two or three transactions before trusting it.
Registration thresholds and the mechanics of when you must register are covered in our VAT guide.
Is Zoho One Worth Considering?
If you can see yourself wanting CRM, accounts, project management, helpdesk and email marketing, Zoho One bundles most of Zoho’s catalogue for a flat per-user fee under an all-employees model, where everyone on payroll is licensed.
One honesty note, because this figure circulates widely: Zoho One’s pricing page publishes no per-user price. The only figure shown is US$90 for the flexible-user model, with no billing period stated, no GBP and no currency selector. So the roughly £30 per user often quoted — including in earlier versions of this article — is not something we could confirm at source.
The method still works, and the inputs on the CRM and accounts side are solid. For five users:
- Zoho CRM Standard: £12 × 5 = £60/month
- Zoho Books Standard: £10/month, per organisation
- Total for the pair: £70/month
Get Zoho One’s current UK all-employees quote, multiply by headcount, and compare against that plus whatever else you would actually buy. If you are only ever going to use CRM and Books, subscribing to the two directly is very likely cheaper. If Projects, Desk and Campaigns are coming within a year or two, One starts to make sense — but price it on a quote, not on a published comparison.
Who This Works Best For
Not everyone needs this. A sole trader doing straightforward invoicing for a handful of clients with no pipeline to manage does not need a CRM at all — Zoho Books on its own, quite possibly the free plan, covers it.
Where the integration earns its keep:
- Small B2B businesses with a sales process, sending proposals or quotes before invoicing. The quote-to-invoice path is the whole argument.
- Teams spanning sales and accounts, where both sides need visibility without extra logins.
- Businesses that want to grow without replatforming, starting with CRM and Books and keeping Zoho One as an option.
- VAT-registered businesses, and now anyone inside MTD for Income Tax, where having the accounts package that files sitting next to the CRM removes a reconciliation step.
FAQ
Is MTD for Income Tax still coming?
No. It has applied since 6 April 2026 to sole traders and landlords with qualifying income above £50,000, with £30,000 following in April 2027 and £20,000 in April 2028. Quarterly deadlines are 7 August, 7 November, 7 February and 7 May.
Is Zoho Books compatible with MTD for Income Tax?
Yes. Zoho Books is HMRC-recognised for it and supports digital records, quarterly updates and the final return. Note the feature is enabled on request through Zoho’s UK support rather than being on by default, so arrange it ahead of a deadline.
Can I use the integration on free plans?
Not on Zoho CRM’s free tier — the Books integration needs Standard at £12 per user. Zoho Books’ free plan does include MTD for VAT and MTD for Income Tax, so the free side is the accounts one.
Does the integration need manual setup?
Yes, once. You connect the apps through Zoho Books’ integration settings and configure field mappings, then sync runs automatically. Not a five-minute job and not especially technical, but budget time for the product catalogue and VAT code mapping.
Will VAT carry over correctly from quotes to invoices?
Yes, provided VAT codes are set up in Books first. Test a couple of transactions before going live.
How much is Zoho Books?
Six UK tiers per organisation: Free, Standard £10, Professional £20, Premium £25, Elite £85 and Ultimate £165 per month on annual billing. Per organisation, not per user, so CRM seats do not inflate it.
Does Zoho Books’ free plan have a turnover limit?
Zoho’s UK pricing page does not state one, though a figure around £35,000 is widely quoted. The published limits are one user plus an accountant, 1,000 invoices and 1,000 expenses a year. Ask Zoho directly if turnover is the deciding factor for you.
The Bottom Line
The integration delivers roughly what it promises: quote to invoice without rekeying, payment status visible in the CRM, and one contact record instead of two drifting apart. It is worth having if you run both a sales process and a bookkeeping function, and it needs Zoho CRM Standard at £12 plus any Zoho Books plan.
The thing to act on, though, is not the integration. MTD for Income Tax has been live since April 2026, the next quarterly deadline is 7 November, and if your qualifying income is above £50,000 you are already in scope. Zoho Books is HMRC-recognised for it and will do the job from the free plan — but the feature is switched on by request, so contact Zoho’s UK support now rather than in the first week of November.
