Accounting Software Setup, Migration & Systems Design

Most software problems are setup problems. We select, configure and migrate systems so the reporting works from day one, then document it so your team can run it.

Who this is for

Businesses moving off desktop or legacy software, or onto Xero, QuickBooks or Sage for the first time. Trades and project businesses whose field-service system does not talk to the ledger, manufacturers who cannot read cost by division, and any team that inherited a setup nobody documented.

01Choosing and moving 3 areas

Software Selection & Scoping

Independent assessment of Xero, QuickBooks, Sage or specialist platforms against how you actually operate.

Software selection and scoping begins with a morning in your business, not a feature comparison. We map how an order becomes an invoice, how a supplier bill gets approved, who touches the bank and what the owner needs to see each month, then test Xero, QuickBooks Online and Sage against that list. The scoping note you receive records the recommendation, the reasons, the apps needed alongside it and the migration plan, priced as a fixed fee before any licence is bought.

Migration & Data Conversion

Moving from desktop or legacy systems with opening balances, history and VAT position intact.

A migration is planned around a cut-over date, usually a VAT quarter end or year end, so there is one clean line between the old system and the new. Before that date we reconcile the trial balance, debtors, creditors and bank in the old system, agree what history comes across and how, and confirm the VAT position including any partially reconciled returns. After cut-over, the opening balances are proved back to the last filed accounts. Migration and data conversion is signed off only when both systems agree.

Chart of Accounts Design

Nominal structure, department and tracking codes built for the reporting you want to see.

Chart of accounts design works backwards from the reports you want to read. We agree the profit and loss layout first, then build the nominal codes to feed it, with a clean split between cost of sales and overheads and enough granularity to be useful without becoming unmanageable. Departments, sites, projects or product lines are handled with tracking dimensions rather than duplicated codes. The finished chart maps to the statutory accounts format, so year end is a rollover rather than a rebuild.

02The platforms 4 areas

Xero Setup & Optimisation

Full configuration, bank rules, tracking categories, repeating templates and app connections.

Most Xero files we inherit were set up in an afternoon and never revisited. Xero setup and optimisation covers the organisation settings, financial year and VAT scheme, the chart, bank feeds with rules that code the routine items, tracking categories for departments or projects, repeating invoices and bills, and the reporting layouts saved for month end. Where a file already exists, we tidy the contacts, archive unused codes and clear the suspense account. You end up with a system your team can close each month without workarounds.

QuickBooks Online Setup & Optimisation

Configuration for trades, CIS and project-based businesses.

QuickBooks Online setup and optimisation is built around the way trades and project businesses invoice: deposits, staged applications, retentions and CIS deductions on both sides. We configure the CIS module so deduction statements and monthly returns come straight from the ledger, set up projects or classes so job margin is visible without a spreadsheet, and connect the bank with rules for the recurring items. Estimates, progress invoicing and supplier bills are set up to match your workflow, and the reports your contracts manager needs are saved and shared.

Sage 50 Support & Reporting

Departmental reporting, nominal restructuring and reconciliation of Sage against bespoke systems.

Plenty of established businesses run Sage 50 well and have no reason to move. Sage 50 support and reporting keeps it that way: departmental analysis set up so each site or division reports its own margin, the nominal ledger restructured without losing history, and the month-end routine documented. Where a job costing, stock or industry system posts into Sage, we reconcile the two at each period end and trace any difference to its source. Year-end files are prepared so the statutory accounts pick up cleanly from the ledger.

Payroll Software Setup

BrightPay and equivalent: scheme setup, migration, employee data and pension integration.

Payroll software setup starts with the PAYE reference, Accounts Office reference and the employer settings that determine every submission afterwards. Employees are loaded from P45s or year-to-date figures when moving mid-year, so RTI submissions carry on without duplicate records. The auto-enrolment pension is connected in BrightPay so assessments and contribution files go to the provider automatically, and payslips, reports and the employer portal are configured for whoever runs the payroll. We run the first payroll alongside your team and check the FPS and EPS before they leave.

03The wider stack 2 areas

App Stack & Integrations

Dext, Hubdoc, A2X, Float, Credit Hound, Simpro, Fieldwire, expense and payment tools.

Each app is chosen for a specific job and connected so data flows one way, with the ledger as the record. Dext or Hubdoc captures bills and receipts at source, A2X turns marketplace settlements into summarised sales and fee entries that reconcile to the payout, and Float reads the ledger for cashflow forecasting. We set the mapping, tax codes and approval rules in each, then test a month before switching the manual process off. App stack and integrations are documented so your team can see what talks to what.

Bespoke & ERP System Reviews

Where an in-house or industry system feeds the ledger, we reconcile the two and fix the gaps.

Industry systems for job costing, stock or property are rarely built with the general ledger in mind, and the interface between the two is where the numbers drift. A bespoke and ERP system review traces a sample of transactions from source to ledger and back, checks the posting rules, VAT treatment and timing, and reconciles sales, purchases and stock between the systems at a period end. You receive a list of the gaps, the fix for each and the reconciliation you should run monthly so the drift stops.

04Making it stick 2 areas

Process Documentation & SOPs

Written procedures so the routine survives staff turnover.

Process documentation and SOPs turn the way the finance function actually runs into short written procedures: how a sales invoice is raised, how a supplier bill is approved and paid, what the bank reconciliation should look like on a Friday, and the month-end checklist with owners and deadlines. Each procedure is written with screenshots from your own system and tested by someone who did not write it. When a bookkeeper leaves or goes on holiday, the next person picks up the folder and the routine carries on.

Team Training & Handover

Practical sessions for your bookkeeper, office manager or finance assistant.

Training is done on your live system with your real transactions, in sessions short enough to be remembered. We cover the daily routine first: bank coding, invoicing, bills and expenses, then the weekly and monthly tasks, then what to do when something does not reconcile. Each session ends with the trainee doing the task unaided while we watch. Team training and handover closes with a written sign-off of what has been covered, a list of what remains with us, and a named person to call when something unfamiliar appears.

Questions

Frequently asked

What is the best accounting software for a small UK business?

There is no single best option. Xero suits most service and product businesses, QuickBooks Online is strong for trades, CIS and project costing, and Sage 50 still fits businesses with heavy stock or departmental reporting. The right choice depends on how you invoice, take payment, manage stock and want to report. We are not tied to any vendor, so we score the options against how you actually operate and recommend one. Read more.

How long does it take to migrate to Xero?

A straightforward move from another cloud product can be completed within a few weeks, while moving from desktop or legacy software with years of history takes longer because opening balances, the VAT position and unreconciled items must be brought across cleanly. The safest point to switch is a VAT quarter end or year end. We plan the cut-over date, convert the data, reconcile the opening position and run both systems briefly in parallel. Read more.

What is a chart of accounts and why does it matter?

The chart of accounts is the list of nominal codes every transaction is posted to, and it determines what your reports can show you. A default chart gives you a profit and loss and a balance sheet but nothing by department, site, project or product line. We design the nominal structure and tracking categories around the reporting you want, then configure the software so coding is consistent from the first invoice. Read more.

Can you connect Dext, Hubdoc or A2X to my accounts?

Yes. Receipt capture tools such as Dext and Hubdoc, marketplace connectors such as A2X and cashflow tools such as Float all integrate with Xero and QuickBooks, but each needs its mappings, tax rates and publishing rules set properly or it creates duplicates and miscoded entries. We select the apps that earn their subscription, configure the integrations, test them against real transactions and document how each one is meant to be used. Read more.

What happens if my team cannot use the new software?

Most failed implementations fail at handover rather than at setup, because nobody wrote the routine down or trained the people who run it. We do not consider a system live until your bookkeeper, office manager or finance assistant can operate it without us. We run practical training on your own data, leave written procedures for each routine task and stay available for questions through the first few month ends. Read more.
