Finance Systems Implementation · UK SMEs

Your finance function has a problem your accounting software alone cannot fix

We find it, design the solution, and implement it — properly, inside your existing Xero or QuickBooks environment, with the right tools around it.

Fraudulent payments after PO matching was implemented

Most UK SMEs are running Xero or QuickBooks — and using about 40% of what those tools and the ecosystem around them can do. The remaining 60% is the difference between a finance function that holds the business back and one that supports it properly. Fintelwise closes that gap.

Five finance problems we fix every day

Each of these is a specific, solvable problem — not a vague inefficiency. If your business has one of them, we know exactly what to do.

⏱️

Your finance team is doing work Xero should be doing

Manual data entry, spreadsheet commissions, invoices raised line by line. The team is busy but not productive. OCR, automation, and proper tool setup removes the manual layer entirely.

🔓

Anyone can commit spend without a formal approval

Bills approved over email, no PO system, same person requests and approves their own spend. One email away from fraud. We build approval workflows that enforce your policies automatically.

📊

You are making decisions without real financial data

No management accounts, no KPI dashboard, no cash flow forecast. Year-end figures arrive 9 months late. We connect Xero to reporting tools that produce management accounts automatically every month.

🔄

You are still on Sage and the migration feels risky

Legacy software cannot connect to modern tools. The migration feels risky because a poorly timed one is. A well-timed migration — done correctly at year end — carries virtually no disruption.

💷

You are profitable on paper but consistently tight on cash

Delayed invoicing, no online payment option, no automated reminders, debtors over 30 days. Cash flow problems at growing service businesses are almost always systems problems — not client problems. We build the invoice-to-cash workflow that fixes it.

From broken to working in three steps

We do not sell software licences. We implement the right combination of tools for your specific situation — and make sure it works properly before we hand it over.

1

Free 30-minute scoping call

We ask structured questions about your finance function, identify the specific problem, and give you an honest view of what a solution would look like and roughly what it would cost. No pitch. No proposal. Just a diagnosis.

2

Paid Discovery Session — written Finance Systems Audit

A structured session where we map your current processes, identify every gap, design the solution, and produce a written Finance Systems Audit document. This document is yours permanently — whether you proceed with us or not.

The document promise: It is detailed enough that any implementer in the world can work from it accurately. You will never again commission a finance system without knowing in advance exactly what you are getting. All Discovery fees are credited in full against the implementation cost if you proceed with us.

Fixed-price implementation — inside your existing environment

We build and configure everything inside your Xero or QuickBooks environment. Fixed price, defined scope, clear timeline. We train your team, hand over a system that runs properly, and step back. No ongoing dependency on us to keep it working.


What we implement — and why

We recommend the right tool for each situation — not the most expensive, not the most complex, and not the one we are most familiar with. Xero or QuickBooks is always the foundation. Everything else plugs in on top.

Fintelwise is not a reseller of any of these tools. We implement them. The licence relationship is directly between you and the software provider — we have no financial incentive to recommend one tool over another.

Real implementations. Real results.

Every case study on this page is a live implementation — not a hypothetical. Client details are anonymised but the problems, solutions, and outcomes are real.

Xero · ApprovalMax · Stripe

Payment cycle cut from 4–5 weeks to approximately one week

A firm was invoicing manually with no online payment option and a chaotic approval process. We built an ApprovalMax workflow with mandatory sign-off, added Stripe payment links to every invoice, and set up automated debtor reminders.

Finance Operations · ApprovalMax

Email-based invoice fraud eliminated with PO matching

Scammers were sending fraudulent emails impersonating the business owner to trigger payments. We implemented a Purchase Order system in ApprovalMax — every bill must match an approved PO before payment can be made.

Government Subcontracting · Xero · Power Query

5 days of weekly manual invoicing reduced to minutes

A finance team of two spent their entire working week manually entering thousands of invoice lines from timesheets. We built a Power Query automation that transforms their workforce export directly into Xero's invoice import format.

Multi-entity · Xero · Fathom

Automated group consolidated accounts across UK and US entities

A group with multiple UK and US companies had inconsistent charts of accounts and no consolidated view. We standardised everything, connected all entities to Fathom, and configured intercompany eliminations.

Built for UK SMEs — 10 to 50 people

We work with businesses that are too big for informal finance processes but not large enough for a full in-house finance transformation team. The sweet spot is a business that knows something is wrong and wants it fixed properly.

The Discovery Session

Start with a written diagnosis

Before any implementation begins, we produce a Finance Systems Audit — a written document that defines exactly what is broken, what needs to change, and what it will cost. You own it permanently. Whether you proceed with us or not.

Tier 1

Quick Fix

£350

45-min session + written summary. One specific problem, one clear solution.

Tier 3

Full Finance Review

£1,100

Two sessions + 10–15 page Finance Transformation document. Full overhauls and migrations.

All Discovery fees are credited in full against your implementation cost if you proceed with us. If you do not — the document is still yours. Any implementer in the world can work from it accurately.


What makes this different

There are plenty of accountants and bookkeepers. There are plenty of software resellers. Fintelwise is neither.

🔍

We diagnose before we prescribe

Every engagement starts with a structured Discovery Session. We never recommend a tool without first understanding the specific problem it needs to solve. A written document comes before any implementation.

🛠️

We implement — we do not advise and disappear

The Finance Systems Audit is a starting point, not a deliverable. The goal is a working system inside your business, configured properly, with your team trained to run it independently.

🎯

We recommend what is right, not what is most profitable

Fintelwise has no financial relationship with any software vendor. We do not earn commission on licences. We recommend the right tool for your situation — even if that tool is simpler and cheaper than the alternatives.
