Relentify vs Zoho Books: Full-Featured Accounting Without the Complexity
Zoho Books is the accounting arm of Zoho's massive software ecosystem. With over 50 products spanning CRM, project management, HR, and more, Zoho positions itself as the everything-suite for businesses. The appeal is obvious: integrate everything you own into one account, and your data flows seamlessly. But "everything" also means complexity. And complexity means you're either learning to navigate 50 different products' conventions in one interface, or paying for features in Books that only make sense when paired with another Zoho product.
Relentify takes the opposite approach: build full-featured accounting software that's genuinely complete on its own. No separate analytics tier. No feature locked behind another product purchase. No "you need Zoho CRM for that." For small businesses tired of paying for breadth when they really just need depth, the question of Relentify vs Zoho Books becomes straightforward.
The Ecosystem Trap
Zoho's strength is also its weakness. If you're already running Zoho CRM, Zoho Projects, and Zoho People, then Zoho Books integrates beautifully — data flows without manual intervention. Fair point. Compare Relentify's CRM offering here if you're evaluating Zoho's full suite.
The trap: Zoho Books is optimised as part of an ecosystem rather than as a standalone product. Some features feel designed to push you toward other Zoho products rather than solving problems within Books itself. Reporting integrations work best with Zoho Analytics (a separate product with its own pricing). Multi-entity consolidation? You need Zoho Analytics. Advanced forecasting? Zoho Analytics. At some point, you're not comparing accounting software — you're comparing the entire Zoho stack.
Relentify is designed to be complete on its own. Reporting, expense management, project tracking, and multi-entity management are all built in. No add-ons. No "professional plan required to unlock this." One interface. One login. One subscription.
This matters more than it sounds. A small business owner doing accounting on a Sunday night doesn't want to switch between three different UIs to understand cash flow, approve expenses, and reconcile the bank. That's not integrated — that's just owning multiple products.
Pricing: Same Price, Different Value
At face value, Zoho Books Professional (£29/month) and Relentify Growth (also £29/month) look equivalent. Dig one level deeper, and the value proposition shifts dramatically.
| Feature | Relentify Growth | Zoho Books Professional |
|---|---|---|
| Monthly price | £29/month | £29/month |
| Users included | Unlimited | 5 |
| Additional users | Free | £3-5/user/month |
| Invoices | Unlimited | Unlimited |
| Purchase orders | Yes | Yes |
| Expense claims + approvals | Yes | Yes |
| Project tracking | Yes | Yes |
| Multi-entity management | Yes | No |
| Multi-currency | Yes | Yes |
| Cash flow forecasting | Yes | Limited |
| Consolidated reporting | Yes | No |
For a team of 15 people, Zoho Books adds £30-50 per month in per-seat charges. That's an extra £360-600 annually. Relentify includes all 15 users at no additional cost.
For multi-entity businesses — say you run two consulting firms or three rental properties — Zoho Books requires separate accounts. Relentify handles it on one subscription with instant entity switching and consolidated reporting included.

What's Actually Included
Invoicing. Both platforms handle it competently. Zoho Books supports custom templates, recurring invoices, and payment reminders. Relentify adds quote-to-invoice conversion, credit note management integrated into the workflow, and partial payment recording directly from the invoice screen. Net result: fewer clicks, faster workflow.
Expense management. Zoho Books requires Professional tier for approval workflows. Relentify includes expense claims, approval workflows, mileage tracking, and automated categorisation on every paid plan. You shouldn't need to upgrade just to manage team expenses.
Automation and workflows. Zoho Books includes workflow automation rules that can trigger actions based on events — sending reminders, updating fields, notifying users. Useful, though configuring automations requires some technical comfort. Relentify includes automation features like automatic payment reminders, recurring invoice generation, and expense categorisation rules. These are configured through simpler interfaces that don't require workflow-builder knowledge.
Reporting. This is where the ecosystem limitation bites hardest. Zoho Books includes P&L, balance sheet, cash flow, and tax reports. Want cash flow forecasting? Separate product. Want financial health scoring or consolidated reports across entities? Zoho Analytics. Relentify includes all of this in the platform — cash flow forecasting, financial health dashboards, KPI tracking, and custom reports without a separate subscription.
Multi-entity management. Zoho Books doesn't support it. Each entity needs its own account. Relentify handles multiple entities on one subscription with intercompany transaction management and consolidated reporting.
Project tracking. Both included. Relentify's version integrates directly with invoicing — you can bill clients straight from tracked project time. Zoho Books' time tracking stays separate from the invoicing workflow.
Purchase orders. Both platforms have them. Zoho Books on Professional; Relentify on every paid plan. Relentify adds approval workflows and escalation rules, which matter when you're managing team spending.
Bank reconciliation and MTD compliance. Both have automatic feeds and transaction matching. HMRC's Making Tax Digital (MTD) requirements apply to most UK businesses with VAT turnover above £85,000. Both platforms support MTD submission to HMRC. Relentify adds a learning rule engine that improves match suggestions based on your categorisation patterns over time.
VAT compliance. Both platforms support standard VAT schemes and MTD submission. Relentify adds support for the flat rate scheme, reverse charge VAT, and period locking. HMRC's VAT guidance explains registration, thresholds, and compliance for UK businesses.
Ecosystem vs. Simplicity: Who Wins?
If you're already using Zoho CRM, Zoho Projects, and Zoho People, and you've got team resources to manage the ecosystem, Zoho Books slots in neatly. You get data flow between products and a unified account.
But realistic scenario: most small business owners aren't running the full Zoho ecosystem. They've got accounting software, CRM, maybe helpdesk, all from different vendors. In that case, Zoho Books becomes just another disconnected tool — except it's optimised for a scenario you're not in.
If you want a platform that's complete without being massive — one that includes accounting, CRM, helpdesk, invoicing, e-signatures, and task management from the same vendor — Relentify is worth evaluating. You're not buying ecosystem breadth; you're buying integrated depth in the tools small businesses actually need.

User Experience
Zoho Books' interface is clean and functional, though it carries design conventions shared across the Zoho ecosystem. This is both a strength (consistency across products if you use many) and a weakness (navigating 50 different products' conventions in one app is disorienting).
Relentify's interface is designed for accounting specifically. Common tasks are accessible without opening three menus. The design is consistent because you're not jumping between six different product teams' interpretations of "dashboard." Navigation feels like it was built for accountants, not retrofitted from a giant platform.
This sounds small until you're doing weekly bank reconciliation and spend five minutes remembering where the button moved after an update.
Support
Zoho Books offers email support and phone support on higher tiers. The support team covers the entire Zoho product range rather than specialising in Books specifically.
Relentify provides live chat support on every plan with AI-assisted initial responses for common questions and human agents for complex issues. If you're stuck at 4 p.m. on Thursday, you can chat with someone immediately rather than waiting for an email response.
Frequently Asked Questions
Does Relentify support multi-currency accounting? Yes. Relentify handles transactions in any currency, automatic conversion on bank feeds, and reporting in your base currency.
Can I use Relentify if I'm registered for VAT? Absolutely. Relentify supports standard VAT schemes, flat rate scheme, reverse charge VAT, and MTD submission directly to HMRC.
How many users can I add to Relentify? Unlimited users at no additional cost on all paid plans. Zoho Books charges £3-5 per additional user beyond five.
Does Relentify handle project tracking? Yes. All paid plans include project tracking with time and expense allocation, profitability reporting, and direct invoicing from tracked time.
Can I manage multiple businesses in Relentify? Yes. Relentify supports multiple entities on a single subscription with instant switching, consolidated reporting, and intercompany transaction management. Zoho Books requires separate accounts per entity.
Is there a free plan? Relentify offers a free Sole Trader tier for single-user freelancers. Paid plans start at £6.30/month and include unlimited users.
What if I'm currently using Xero or Wave? We have a dedicated migration guide for Xero users. For Wave, here's how we compare — Wave is free but lacks team expense management and workflow automation.

We include accounting, CRM, helpdesk, invoicing, e-signatures, bookings, and more on a single subscription without per-seat charges.
The Bottom Line
Zoho Books is a capable accounting product — if you're already a Zoho customer with CRM, Projects, and People all in place, the ecosystem integration has real value.
For everyone else: Zoho Books is a solid single product hampered by the fact that it's designed as part of an ecosystem rather than to stand alone.
Relentify is built to be complete on its own. Unlimited users. Full reporting without add-ons. Multi-entity management. Project tracking. Approval workflows. All included. All at lower total cost of ownership for most small businesses.
The best accounting software is one you actually use because it doesn't get in your way. If that's a unified platform with depth rather than breadth, try Relentify free for 14 days.
